"Didn't understand or not fully understand" is the most common situation that students experience when they learn medical biochemistry and molecular biology (MBMB). Therefore, the primary task of teaching MBMB is to help students overcome the difficulties in "conceptual understanding." The core of the solution to these problems…

Vygotsky's Zone of Proximal Development (ZPD) provides an important understanding of learning, but its implications for teachers are often unclear or limited and could be further explored. We use conceptual analysis to sharpen the ZPD as a teaching tool, illustrated with examples from teaching critical thinking in zoology. Our conclusions are…

Knowledge of scientific models and their uses is a concept that has become a key benchmark in many of the science standards of the past 30 years, including the proposed Next Generation Science Standards. Knowledge of models is linked to other important nature of science concepts such as theory change which are also rising in prominence in newer…

The Lawson Classroom Test of Scientific Reasoning (LCTSR) was used to gauge the relative effectiveness of three different methods of pedagogy, "Reading, Presenting, and Questioning" (RPQ), "Experimenting and Discussion" (ED), and "Traditional Methods" (TM), on increasing students' level of scientific thinking. The…

The impulse to investigate the natural world is deeply rooted in our earliest childhood experiences. This notion has long guided researchers to uncover the cognitive mechanisms underlying the development of scientific reasoning in children. Until recently, however, research in cognitive development and education followed largely independent…

Considers how theories of learning can inform the practice of science teaching in formal settings and describes two broad strands of learning theory that have been drawn upon in science education, namely individual and sociocultural views. Shows how aspects of both views can usefully inform understanding of teaching and learning in science in…

This paper discusses the nature of cognitive research and its implications for learning and teaching science. In addition to needing adequate financial support, active involvement of scientists and educators, and education of teachers, two other factors should loom large in the development of new instructional materials in science and in the…

This article examines cognitive models of peer learning in school and the implications that these models have for the teaching of science in primary schools. The article is a product of the European Commission, Socrates Comenius 2.1 funded project "The Implementation of Scientific Thinking in (Pre) Primary Schools Settings (STIPPS)" project…

This commentary refers to a recent paper (1975) by Sayer and Ball in this journal concerning the relationships between formal operational thought and science achievement, and requests additional information on the representativeness of the sample and the performance of boys and girls on the Piagetian tasks. The requested information is provided.…

The development of the concept of matter was explored in children aged 3-13. Eighty four children were asked to classify four sets of objects and matter and to explain their classifications during interviews. Younger children tended to classify using a mixture of extensive properties (properties of objects) and intensive properties (properties of…

Reviews Piagetian concepts, the identification of student cognitive level of development, and chemistry instruction. (SL)

Discusses instructor considerations to be made concerning student cognitive development in preparing and teaching introductory chemistry. (SL)

Discusses the "neo-Piagetian" concepts of Juan Pascual-Leone which are present in Piaget's theory. The concepts presented are the repertoire of schemes, mental processing capacity, and field dependence-independence. (Author/SA)

Synthesizes current thought in neuropsychology, philosophy of cognition, and science education. Suggests that dualistic views and those based solely on biological structural-functional analyses may be insufficient to explain the active role of the learner. Presents 10 principles of neurocognition as a context for analysis of learner-centered…

Reports results of a study examining the Piagetian stages of Italian secondary school students in which student responses to three puzzles were analyzed. Compares results with studies done in the United States and the United Kingdom. (CS)
