Example choice

Last updated

Example choice is a teaching method that has been developed and explored at the University of Bergen. The main objective is to make mathematics and science teaching more interesting and relevant to the daily life of students. One study by Perkins, Gratny, Adams, Finkelstein, and Wieman found that interest in physics declined during a semester-long introductory calculus-based mechanics course. Whereas 19% of the students reported increased interest in physics, 45% reported that their interest in physics decreased. When interest increased, the leading reason was that students reported to see a connection between physics and the real world. Example choice aims to highlight the connection between formal principles and their relevance for everyday life in order to make school instruction a relevant experience for the child, as already John Dewey called for in his book "School and Society". For him, connecting instructional content to everyday life was the only legitimate way to make things interesting, as noted in his essay "Interest and Effort".

In traditional teaching, formal principles (laws, formula, problem solving procedures) in mathematics and science are often taught abstractly and then illustrated by an example. In example choice, by contrast, students are given multiple example tasks that all can be solved using the formal principle. The examples pertain to different topics, and each student is instructed to choose the most interesting example. This example is used to explain the formal principle.

For example, when teaching the joint probability of two independent events, teachers often explain the abstract procedure (p1 * p2) first and illustrate this procedure with an example (e.g., throwing a die twice). In example choice, by contrast, teachers first collect or construct examples from topics that are of potential interest to high school students, such as contracting hereditary diseases, contraception, or winning in a two-step lottery to meet one's favorite artist. After the students selected the example that interests them most, they are given a problem related to the chosen example that they have to try to solve. After the solution attempt, the principle behind the joint probability of two independent events will be explained, using the chosen example. Teachers may then use the other examples in order to deepen the understanding of joint probabilities, for example by using worked examples.

A study observed that example choice increased interest in learning an abstract principle, and participants in the study invested more time to learn. In other words, students are the producers of learning. [1]

Example choice is difficult to use in traditional teaching because teachers often do not know the interests of their students. Even if they know these interests, a teacher would need much time and effort to find examples. With new technologies, teachers and students can help build a database of examples that users can retrieve when the formal principle has to be learned.

Educational psychology Branch of psychology concerned with the scientific study of human learning

Educational psychology is the branch of psychology concerned with the scientific study of human learning. The study of learning processes, from both cognitive and behavioral perspectives, allows researchers to understand individual differences in intelligence, cognitive development, affect, motivation, self-regulation, and self-concept, as well as their role in learning. The field of educational psychology relies heavily on quantitative methods, including testing and measurement, to enhance educational activities related to instructional design, classroom management, and assessment, which serve to facilitate learning processes in various educational settings across the lifespan.

A teaching method comprises the principles and methods used by teachers to enable student learning. These strategies are determined partly on subject matter to be taught and partly by the nature of the learner. For a particular teaching method to be appropriate and efficient it has to be in relation with the characteristic of the learner and the type of learning it is supposed to bring about. Suggestions are there to design and selection of teaching methods must take into account not only the nature of the subject matter but also how students learn. In today's school the trend is that it encourages much creativity. It is a known fact that human advancement comes through reasoning. This reasoning and original thought enhances creativity.

Instructional scaffolding is the support given to a student by an instructor throughout the learning process. This support is specifically tailored to each student; this instructional approach allows students to experience student-centered learning, which tends to facilitate more efficient learning than teacher-centered learning. This learning process promotes a deeper level of learning than many other common teaching strategies.

Cognitivism (psychology) Theoretical framework for understanding the mind

In psychology, cognitivism is a theoretical framework for understanding the mind that gained credence in the 1950s. The movement was a response to behaviorism, which cognitivists said neglected to explain cognition. Cognitive psychology derived its name from the Latin cognoscere, referring to knowing and information, thus cognitive psychology is an information-processing psychology derived in part from earlier traditions of the investigation of thought and problem solving.

Mathematics education Mathematics teaching, learning and scholarly research

In contemporary education, mathematics education is the practice of teaching and learning mathematics, along with the associated scholarly research.

Experiential education Philosophy of education

Experiential education is a philosophy of education that describes the process that occurs between a teacher and student that infuses direct experience with the learning environment and content. The term is not interchangeable with experiential learning; however experiential learning is a sub-field and operates under the methodologies of experiential education. The Association for Experiential Education regards experiential education as "a philosophy that informs many methodologies in which educators purposefully engage with learners in direct experience and focused reflection in order to increase knowledge, develop skills, clarify values, and develop people's capacity to contribute to their communities". Experiential education is the term for the philosophy and educational progressivism is the movement which it informed.

Principles and Standards for School Mathematics (PSSM) are guidelines produced by the National Council of Teachers of Mathematics (NCTM) in 2000, setting forth recommendations for mathematics educators. They form a national vision for preschool through twelfth grade mathematics education in the US and Canada. It is the primary model for standards-based mathematics.

A lesson plan is a teacher's detailed description of the course of instruction or "learning trajectory" for a lesson. A daily lesson plan is developed by a teacher to guide class learning. Details will vary depending on the preference of the teacher, subject being covered, and the needs of the students. There may be requirements mandated by the school system regarding the plan. A lesson plan is the teacher's guide for running a particular lesson, and it includes the goal, how the goal will be reached and a way of measuring how well the goal was reached.

Classroom management

Classroom Management is a term teachers use to describe the process of ensuring that classroom lessons run smoothly without disruptive behavior from students compromising the delivery of instruction. The term also implies the prevention of disruptive behavior preemptively, as well as effectively responding to it after it happens.

Transfer of learning occurs when people apply information, strategies, and skills they have learned to a new situation or context. Transfer is not a discrete activity, but is rather an integral part of the learning process. Researchers attempt to identify when and how transfer occurs and to offer strategies to improve transfer.

Discovery learning Technique of inquiry-based learning and is considered a constructivist based approach to education

Discovery learning is a technique of inquiry-based learning and is considered a constructivist based approach to education. It is also referred to as problem-based learning, experiential learning and 21st century learning. It is supported by the work of learning theorists and psychologists Jean Piaget, Jerome Bruner, and Seymour Papert.

Inquiry-based learning is a form of active learning that starts by posing questions, problems or scenarios. It contrasts with traditional education, which generally relies on the teacher presenting facts and their own knowledge about the subject. Inquiry-based learning is often assisted by a facilitator rather than a lecturer. Inquirers will identify and research issues and questions to develop knowledge or solutions. Inquiry-based learning includes problem-based learning, and is generally used in small scale investigations and projects, as well as research. The inquiry-based instruction is principally very closely related to the development and practice of thinking and problem solving skills.

Statistics education is the practice of teaching and learning of statistics, along with the associated scholarly research.

In mathematics education, a representation is a way of encoding an idea or a relationship, and can be both internal and external. Thus multiple representations are ways to symbolize, to describe and to refer to the same mathematical entity. They are used to understand, to develop, and to communicate different mathematical features of the same object or operation, as well as connections between different properties. Multiple representations include graphs and diagrams, tables and grids, formulas, symbols, words, gestures, software code, videos, concrete models, physical and virtual manipulatives, pictures, and sounds. Representations are thinking tools for doing mathematics.

One of the most visible approaches to peer learning comes out of cognitive psychology, and is applied within a "mainstream" educational framework: "Peer learning is an educational practice in which students interact with other students to attain educational goals." Other authors including David Boud describe peer learning as a way of moving beyond independent to interdependent or mutual learning among peers. In this context, it can be compared to the practices that go by the name cooperative learning. However, other contemporary views on peer learning relax the constraints, and position "peer-to-peer learning" as a mode of "learning for everyone, by everyone, about almost anything." Whether it takes place in a formal or informal learning context, in small groups or online, peer learning manifests aspects of self-organization that are mostly absent from pedagogical models of teaching and learning.
