Defference Between Inductive, Deductive and Abductive methods of Teaching

 

Meaning:

 

     The inductive method of teaching means that the teacher presents the rule through situations and sentences and does guided practice, then the learners do free practice. After that, the teacher deduces or elicits the rule form from the learners themselves by themselves.

 



    An inductive approach to teaching language starts with examples and asks learners to find rules. It can be compared with a deductive approach that starts by giving learners rules, then examples, then practice.

 

Example
Learners listen to a conversation that includes examples of the use of the third conditional. The teacher checks that the students understand the meaning of its use through checking learners' comprehension of the listening text, and only after this focuses on the form, using the examples from the text to elicit rules about the form, its use and its pronunciation.

 

In the classroom
Inductive approaches to presenting new language are commonly found in course books, and form part of a general strategy to engage learners in what they learn. Some learners may need introduction to inductive approaches since they may be more familiar, and feel more comfortable, with a deductive approach. The deductive method of teaching means that the teacher presents the rule, gives a model, then the learners do free practice and answer exercises.

                         
 Definitions:

 

Induction:

       From The Oxford English Dictionary (OED); to induce (in relation to science and logic) means “to derive by reasoning, to lead to something as a conclusion, or inference, to suggest or imply,” and induction “as the process of inferring a general law or principle from observation of particular instances.” 

 

Abduction:

    Another version is the “adducing (pulling together) of a number of separate facts, particulars, etc. especially for the purpose of proving a general statement.”

 

Deduction:

     The OED definition of to deduce is “to show or hold a thing to be derived from etc…” or “to draw as a conclusion from something known or assumed, to infer”;

    Deduction thus, is “inference by reasoning from generals to particulars,” or “the process of deducing from something known or assumed…”

 

Differences:

Induction and deduction are pervasive elements in critical thinking. They are also some what misunderstood terms. Arguments based on experience or observation are best expressed inductively, while arguments based on laws or rules are best expressed deductively. Most arguments are mainly inductive. In fact, inductive reasoning usually comes much more naturally to us than deductive reasoning.

    Inductive reasoning moves from specific details and observations to the lore general underlying principles or processes that explain them(e.g., newton’s law of Gravity). The premises of an inductive argument  are believed to support the conclusion, but don't ensure it. Thus, the conclusion of an induction is regarded as a hypothesis. In the inductive method, also called the scientific method, observation of nature is the authority.

     In contrast, deductive reasoning typically moves general treuths to specific conclusion. It opens with an expansive explanation and continues with predication for specific observations supporting it.Deductive reasoning is narrow in nature and is concerned with testing or confirming a hypothesis.

     Deductive reasoning leads to a confirmation(or not) of our original theories. It guarantees the correctness of a conclusion. Logic is the authority in the deductive method.

 

Comparison:

 

Deductive reasoning:

        Deductive reasoning works from the "general" to the "specific". This is also called a "top-down" approach. The deductive reasoning works as follows: think of a theory about topic and then narrow it down to specific hypothesis (hypothesis that we test or can test). Narrow down further if we would like to collect observations for hypothesis (note that we collect observations to accept or reject hypothesis and the reason we do that is to confirm or refute our original theory).

       In a conclusion, when we use deduction we reason from general principles to specific cases, as in applying a mathematical theorem to a particular problem or in citing a law or physics to predict the outcome of an experiment.

 

Inductive reasoning: 


       Inductive reasoning works the other way, it works from observation (or observations) works toward generalizations and theories. This is also called a “bottom-up  approach. Inductive reason starts from specific observations , look for patterns, regularities (or irregularities), formulate hypothesis that we could work with and finally ended up developing general theories or drawing conclusion.

      In a conclusion, when we use Induction we observe a number of specific instances and from them infer a general principle or law. Inductive reasoning is open-ended and exploratory especially at the beginning. On the other hand, deductive reasoning is narrow in nature and is concerned with testing or confirming hypothesis. 


Properties of Deduction

     In a valid deductive argument, all of the content of the conclusion is present, at least implicitly, in the premises. Deduction is non ampliative. If the premises are true, the conclusion must be true. Valid deduction is necessarily truth preserving.

     If new premises are added to a valid deductive argument (and none of its premises are changed or deleted) the argument remains valid. Deductive validity is an all-or-nothing matter; validity does not come in degrees. An argument is totally valid, or it is invalid. 

 

Properties of Induction:

       Induction is implicative. The conclusion of an inductive argument has content that goes beyond the content of its premises. A correct inductive argument may have true premises and a false conclusion. Induction is not necessarily truth preserving.

Cognative Theory Piaget Stages of Development

 

What Are the Piaget Stages of Development?



Piaget's stages of development are part of a theory about the phases of normal intellectual development, from infancy through adulthood. This includes thought, judgment, and knowledge. The stages were named after psychologist and developmental biologist Jean Piaget, who recorded the intellectual development and abilities of infants, children, and teens.

Piaget's four stages of intellectual (or cognitive) development are:

  • Sensorimotor. Birth through ages 18-24 months
  • Preoperational. Toddlerhood (18-24 months) through early childhood (age 7)
  • Concrete operational. Ages 7 to 11
  • Formal operational. Adolescence through adulthood

Piaget acknowledged that some children may pass through the stages at different ages than the averages noted above. He also said some children may show characteristics of more than one stage at a given time.

But he insisted that:

  • Cognitive development always follows this sequence.
  • Stages cannot be skipped.
  • Each stage is marked by new intellectual abilities and a more complex understanding of the world.

Piaget's 1936 theory broke new ground because he found that children's brains work in very different ways than adults'. Before his theory, many believed that children were not yet capable of thinking as well as grown-ups.

Some experts disagree with his idea of stages. Instead, they see development as continuous. Another criticism is that Piaget didn't consider how a child's culture and social environment affect their development.

Sensorimotor Stage

During the early stages, according to Piaget, infants are only aware of what is right in front of them. They focus on what they see, what they are doing, and physical interactions with their immediate environment.

Because they don't yet know how things react, they're constantly experimenting. They shake or throw things, put things in their mouth, and learn about the world through trial and error. The later stages include goal-oriented behavior that leads to a desired result.

Between ages 7 and 9 months, infants begin to realize that an object exists even though they can no longer see it. This important milestone -- known as object permanence -- is a sign that memory is developing.

After infants start crawling, standing, and walking, their increased physical mobility leads to more cognitive development. Near the end of the sensorimotor stage (18-24 months), infants reach another important milestone -- early language development, a sign that they are developing some symbolic abilities.

Preoperational Stage

During this stage (toddler through age 7), young children are able to think about things symbolically. Their language use becomes more mature. They also develop memory and imagination, which allows them to understand the difference between past and future, and engage in make-believe.

But their thinking is based on intuition and still not completely logical. They cannot yet grasp more complex concepts such as cause and effect, time, and comparison

Concrete Operational Stage

At this time, elementary-age and preadolescent children -- ages 7 to 11 -- show logical, concrete reasoning.

Children's thinking becomes less focused on themselves. They're increasingly aware of external events. They begin to realize that their own thoughts and feelings are unique and may not be shared by others or may not even be part of reality.

Formal Operational Stage

Adolescents who reach this fourth stage of intellectual development -- usually at age 11-plus -- are able to use symbols related to abstract concepts, such as algebra and science. They can think about things in systematic ways, come up with theories, and consider possibilities. They also can ponder abstract relationships and concepts such as justice.

Although Piaget believed in lifelong intellectual growth, he insisted that the formal operational stage is the final stage of cognitive development. He also said that continued intellectual development in adults depends on the buildup of knowledge.

Concepts of Piaget's Stages of Development

Along with the stages of development, Piaget's theory has several other main concepts.

Schemas are thought processes that are essentially building blocks of knowledge. A baby, for example, knows that it must make a sucking motion to eat. That's a schema.

Assimilation is how you use your existing schemas to interpret a new situation or object. For example, a child seeing a skunk for the first time might call it a cat.

Accommodation is what happens when you change a schema, or create a new one, to fit new information you learn. The child accommodates when they understand that not all furry, four-legged creatures are cats.

Equilibrium happens when you're able to use assimilation to fit in most of the new information you learn. So you're not constantly adding new schemas.

Using Piaget's Stages of Development

Piaget's theory has influenced education and parenting. Here are some practical ways teachers and parents can put his ideas to work:

  • Remember that kids often learn best by doing things, rather than hearing about them. Learning to solve problems isn't something that can be taught. It must be discovered.
  • The process of learning is as important (or more so) than the end result.
  • Don't try to teach a child something they aren’t ready to learn. According to Piaget's stages, kids must master one level before they move on to the next.
  • Kids learn as much from each other as from parents or teachers. Give them projects to do together, as well as individual tasks.

Teaching Methods

 

Teaching Methods

The term teaching method

refers to the general principles, pedagogy and management strategies used for classroom instruction.

Your choice of teaching method depends on what fits you — your educational philosophy, classroom demographic, subject area(s) and school mission statement.

Teaching theories can be organized into four categories based on two major parameters: a teacher-centered approach versus a student-centered approach, and high-tech material use versus low-tech material use.

Interested in developing your skills as a teacher? Explore online education short courses designed to give you an in depth understanding of various skills in teaching.

Teacher-Centered Approach to Learning

Taken to its most extreme interpretation, teachers are the main authority figure in a teacher-centered instruction model. Students are viewed as “empty vessels” External link  who passively receive knowledge from their teachers through lectures and direct instruction, with an end goal of positive results from testing and assessment. In this style, teaching and assessment are viewed as two separate entities; student learning is measured through objectively scored tests and assessments.

Learn more about the different teaching styles that use a teacher-centered approach.

Student-Centered Approach to Learning

While teachers are still an authority figure in a student-centered teaching model, teachers and students play an equally active role in the learning process.

The teacher’s primary role is to coach and facilitate student learning and overall comprehension of material, and to measure student learning through both formal and informal forms of assessment, like group projects, student portfolios, and class participation. In the student-centered classroom, teaching and assessment are connected because student learning is continuously measured during teacher instruction.

Learn more about the different teaching styles that use a student-centered approach.

High Tech Approach to Learning

Advancements in technology have propelled the education sector in the last few decades. As the name suggests, the high tech approach to learning utilizes different technology to aid students in their classroom learning. Many educators use computers and tablets in the classroom, and others may use the internet to assign homework. The internet is also beneficial in a classroom setting as it provides unlimited resources. Teachers may also use the internet in order to connect their students with people from around the world.


Low Tech Approach to Learning

While technology undoubtedly has changed education, many educators opt to use a more traditional, low tech approach to learning. Some learning styles require a physical presence and interaction between the educator and the student. Additionally, some research has shown that low-tech classrooms may boost learning. For example, students who take handwritten notes have better recall than students who take typed notes External link . Another downside of technology in the classroom may be that students exposed to spell check and autocorrect features at an earlier age may be weaker in spelling and writing skills External link . Ultimately, tailoring the learning experience to different types of learners is incredibly important, and sometimes students work better with a low-tech approach.

Here are some examples of low technology usage in different teaching methodologies:

  • Kinesthetic learners have a need for movement when learning. Teachers should allow students to move around, speak with hands and gestures.
  • Expeditionary learning involves “learning by doing” and participating in a hands-on experience. Students may participate in fieldwork, learning expeditions, projects or case studies to be able to apply knowledge learned in the classroom to the real world, rather than learning through the virtual world.
  • Many types of vocational or practical training cannot be learned virtually, whether it be a laboratory experiment or woodworking.

Through these different approaches to teaching, educators can gain a better understanding of how best to govern their classrooms, implement instruction, and connect with their students. Within each category of teacher and student centeredness and tech usage, there are specific teaching roles or “methods” of instructor behavior that feature their own unique mix of learning and assessment practices. Learn more about each one to find the best fit for your classroom.

Teacher-Centered Methods of Instruction

Direct Instruction (Low Tech)

Direct instruction is the general term that refers to the traditional teaching strategy that relies on explicit teaching through lectures and teacher-led demonstrations.

In this method of instruction, the teacher might play one or all of the following roles:

As the primary teaching strategy under the teacher-centered approach, direct instruction utilizes passive learning, or the idea that students can learn what they need to through listening and watching very precise instruction. Teachers and professors act as the sole supplier of knowledge, and under the direct instruction model, teachers often utilize systematic, scripted lesson plans. Direct instruction programs include exactly what the teacher should say, and activities that students should complete, for every minute of the lesson.

Because it does not include student preferences or give them opportunities for hands-on or alternative types of learning, direct instruction is extremely teacher-centered. it’s also fairly low-tech, often relying on the use of textbooks and workbooks instead of computers and 1:1 devices.

Flipped Classrooms (High Tech)

The idea of the flipped classroom began in 2007 when two teachers began using software that would let them record their live lectures External link . By the next school year, they were implementing pre-recorded lectures and sharing the idea of what became known as the flipped classroom.

Broadly, the flipped classroom label describes the teaching structure that has students watching pre-recorded lessons at home and completing in-class assignments, as opposed to hearing lectures in class and doing homework at home. Teachers who implement the flipped classroom model often film their own instructional videos, but many also use pre-made videos from online sources.

A key benefit of the flipped classroom model is that it allows for students to work at their own pace if that is how the teacher chooses to implement it. In some cases, teachers may assign the same videos to all students, while in others, teachers may choose to allow students to watch new videos as they master topics (taking on a more “differentiated” approach).

But despite this potential for more student-centeredness, flipped classroom models are still mostly based on a teacher’s idea of how learning should happen and what information students need, making it chiefly teacher-centered. From a technology perspective, the system hinges on pre-recorded lessons and online activities, meaning both students and teachers need a good internet connection and devices that can access it.

Kinesthetic Learning (Low Tech)

Sometimes known as tactile learning"or "hands-on learning", kinesthetic learning is based on the idea of multiple intelligences External link , requiring students to do, make, or create. In a kinesthetic learning environment, students perform physical activities rather than listen to lectures or watch demonstrations. Hands-on experiences, drawing, role-play, building, and the use of drama and sports are all examples of kinesthetic classroom activities.

Though a great way to keep students engaged and, at times, simply awake, very few classrooms employ kinesthetic learning activities exclusively. One reason is that, despite the popularity of learning style theories, there is a lack of researched-based evidence that shows that teaching to certain learning styles produces better academic results External link .

One upside is that kinesthetic learning is rarely based on technology, as the method values movement and creativity over technological skills. That means it’s cheap and fairly low-barrier to adopt, as well as a welcome break from students’ existing screen time. Kinesthetic learning can be more student-centered than teacher-centered when students are given the choice of how to use movement to learn new information or experience new skills, so it’s also adaptable to a teacher’s particular classroom preferences.

Student-Centered Methods of Instruction

Differentiated Instruction (Low Tech)

Differentiated instruction is the teaching practice of tailoring instruction to meet individual student needs. It initially grew popular with the 1975 Individuals with Disabilities Education Act External link  (IDEA), which ensured all children had equal access to public education. The Individualized Education Programs External link  (IEPs) that started under IDEA helped classroom teachers differentiate for students with special needs. Today, differentiated instruction is used to meet the needs of all types of learners.

Teachers can differentiate in a number of ways: how students access content, the types of activities students do to master a concept, what the end product of learning looks like, and how the classroom is set up. Some examples of differentiation include: having students read books at their own reading levels, offering different spelling lists to students, or meeting in small groups to reteach topics.

Though differentiation is focused on individual student needs, it is mostly planned and implemented by the teacher. And technology, though a potential aid, is not a hallmark of the differentiated teaching style, making it a fairly traditional, low-barrier method to adopt.

Inquiry-based Learning (High Tech)

Based on student investigation and hands-on projects, inquiry-based learning is a teaching method that casts a teacher as a supportive figure who provides guidance and support for students throughout their learning process, rather than a sole authority figure.

In this method of instruction, the teacher might play one or all of the following roles:

Teachers encourage students to ask questions and consider what they want to know about the world around them. Students then research their questions, find information and sources that explain key concepts and solve problems they may encounter along the way. Findings might be presented as self-made videos, websites, or formal presentations of research results.

Inquiry-based learning falls under the student-centered approach, in that students play an active and participatory role in their own learning. But teacher facilitation is also extremely key to the process. Usually, during the inquiry cycle, every student is working on a different question or topic. In this environment, teachers ask high-level questions and make research suggestions about the process rather than the content. At the end of the inquiry cycle, students reflect on the experience and what they learned. They also consider how it connects to other topics of interest, as an inquiry on one topic often results in more questions and then an inquiry into new fields External link .

Inquiry-based learning can make great use of technology through online research sites, social media, and the possibility for global connections with people outside of the community. But depending on the subject at hand, it doesn’t necessarily require it.

Expeditionary Learning (High Tech)

Expeditionary learning is based on the ideas of the educator who founded Outward Bound External link , and is a form of project-based learning in which students go on expeditions and engage in in-depth study of topics that impact their schools and communities.

The learning in this model includes multiple content areas so that students can see how problem-solving can happen in the real world--ideally, their own worlds. A student in a big city, for example, might study statistics about pollution, read information about its effects, and travel to sites in their city that have been impacted by the problem. When they have a good understanding of the circumstances, students and teachers work to find a solution they can actively implement.

Technology-wise, G Suite (Google Docs, Sheets, and Drive) and internet access can aid student research, presentation, and implementation of projects. But it's the hands-on work and getting out into the community that’s the cornerstone of this methodology.

Personalized Learning (High Tech)

Personalized learning External link  is such a new educational model that its definition is still evolving. At the heart of the model, teachers have students follow personalized learning plans that are specific to their interests and skills. Student self-direction and choice in the curriculum are hallmarks of personalized learning.

Assessment is also tailored to the individual: schools and classrooms that implement personalized learning use competency-based progression, so that students can move onto the next standards or topics when they’ve mastered what they’re currently working on. That way, students in personalized learning classrooms can progress to work beyond their grade level as they master topics, while students who need additional help have that time built into their daily schedules as well.

There’s also room for an emphasis on college and career readiness in personalized learning environments. Students who don’t require remediation or extension work can instead work with teachers to nurture social skills and other or 21st-century skills lessons and receive mentoring.

Personalized learning is extremely student centered, but teachers are required to teach lessons, look at frequent assessment data, and meet with students to make any necessary changes to their learning plans. They’ll also need to have a certain comfort level with technology: the differentiated and personalized instruction that students receive often come in the form of online lessons and programs, so teachers must be able to navigate virtual platforms with ease.

Game-based Learning (High Tech)

Game-based learning comes from the desire to engage students in more active learning in the classroom External link . Because they require students to be problem solvers and use soft skills that they will need as adults, games are a great way to encourage a “mastery” mindset, rather than a focus on grades.

In a game-based learning environment, students work on quests to accomplish a specific goal (learning objective) by choosing actions and experimenting along the way. As students make certain progress or achievements, they can earn badges and experience points, just like they would in their favorite video games.

Game-based learning requires a lot of time and planning on the teachers’ part. Fortunately, there is software that makes this process much easier, like 3DGameLab External link  and Classcraft External link . Teachers who use this software may be better at differentiating quests for students because of the data the programs provide.

Because teachers play a big role in planning and creating content under this model, game-based learning isn’t completely student-centered. But it is still very much focused on the student, who works at their own pace and makes independent choices in a gamified environment.

Differences between Testing, Assessment, and Evaluation

 

Differences between Testing, Assessment, and Evaluation





 

What Do We Mean by Testing, Assessment, and Evaluation?

When defined within an educational setting, assessment, evaluation, and testing are all used to measure how much of the assigned materials students are mastering, how well student are learning the materials, and how well student are meeting the stated goals and objectives. Although you may believe that assessments only provide instructors with information on which to base a score or grade, assessments also help you to assess your own learning.

Education professionals make distinctions between assessment, evaluation, and testing. However, for the purposes of this tutorial, all you really need to understand is that these are three different terms for referring to the process of figuring out how much you know about a given topic and that each term has a different meaning. To simplify things, we will use the term "assessment" throughout this tutorial to refer to this process of measuring what you know and have learned.

In case you are curious, here are some definitions:

  • test or quiz is used to examine someone's knowledge of something to determine what he or she knows or has learned. Testing measures the level of skill or knowledge that has been reached.
  • Evaluation is the process of making judgments based on criteria and evidence.
  • Assessment is the process of documenting knowledge, skills, attitudes and beliefs, usually in measurable terms. The goal of assessment is to make improvements, as opposed to simply being judged. In an educational context, assessment is the process of describing, collecting, recording, scoring, and interpreting information about learning.

Why is Assessment Important?

Hopefully by this point in your life you have discovered that learning can be fun! You have probably also realized that you are constantly learning, whether you are in a classroom, a car, or a kitchen.

Assessment helps you build confidence in your ability to learn.

Perhaps you have heard that the global work culture is changing. Unlike your grandfather, you will probably have a number of different jobs and careers during your lifetime. In order to be successful, you will need to have confidence in your ability to learn and you will need to become a lifelong learner. Assessment plays a key role in developing your confidence in your ability to learn, as well as in developing your lifelong learning skills.

Types of Assessments

 

Assessments can be delivered in a variety of ways. Don't assume one is easier than another, although the way you study might differ depending on the type of assessment. You need to prepare for all assessments, no matter what the delivery method is.

Conventional Exams

Typical exams are delivered in a proctored classroom setting with a specific period of time to complete a variety of questions and question types. This type of exam is usually "paper and pencil" but could also be delivered via an electronic device like a computer.

Open Book Exams (completed in class)

Open book exams may consist of many different question types. Because you are given the opportunity to consult print resources, expectations may be higher for answers to contain more detail and be more complex in their analysis of the question or statement. It is very important to pay special attention to directives in open book exams. If the exam is an open book math assessment, you will be expected to show detailed work as to how they reached their solution to the problem. If the exam is primarily or completely essay, you may be expected to use quotes, cite sources, and provide more details.

In an open book exam you will likely be evaluated more on understanding than on recall and memorization. Open book exams test your ability to find and use information for problem solving and to deliver well-structured and well-presented arguments and solutions. You may be expected to apply material to new situations, analyze elements and relationships, and demonstrate that you have synthesized the material through the structure of your answer and how well you have provided supporting evidence for your answer.

Terms & Directives

Directives ask you to answer or present information in a particular way. For a list of words and explanations, see Study Guides and Strategies, essay terms.

Tips for Preparing for Open Book Exams

  • Stay current on readings and class assignments.
  • Prepare brief, concise notes on ideas and concepts being tested.
  • Carefully select what you intend to bring with you to the exam.
  • Challenge yourself with how you would answer questions, and what options and resources you may need to consider.
  • Pre-write answers to questions you anticipate might be on the exam and include your own commentary on the information that will provide fuel for your arguments and demonstrate that you have thought through the materials.
  • Organize your reference materials:

- Make your reference materials as user-friendly as possible so that you don't lose time locating what you need.

- Familiarize yourself with the format, layout and structure of your textbooks and source materials.

- Organize textbooks and source materials with your class notes for speedy retrieval and index ideas and concepts with pointers and/or page numbers in the source material.

- Develop a system of tabs or sticky notes, color coding, concept maps, etc. to mark important summaries, headings, and sections.

- Write short, manageable summaries of content for each grouping.

- List data and formulas separately for easy access.

Tips for Taking Open Book Exams

  • Read the questions carefully to understand what is expected.
  • Quickly review the number of questions and note how much time each could take.
  • First answer the questions that you are confident about and/or that will not require much time to check the resources.
  • Leave more complex and difficult questions for later.
  • Aim for concise, accurate, and thoughtful answers that are based on evidence.
  • Use quotations

- to illustrate a point or act as a discussion point.

- to draw on the authority of the source.

- when you can not say it better in your own words.

  • Quotations can be short.
  • A reference to a quote may be as effective as the quote itself.

  • Guard against overquoting – extensive quoting may detract from your point or argument.
