Large curricular changes of the 1960s brought about by the ChemStudy and Chemical Bond Approach initiatives were generally successful, but they also created learning problems. These were well recognized by a series of surveys in 1971. Recent surveys

Problem Based Learning (PBL) and Concept Mapping (CM) have parallel purposes, both based on a constructivist view of learning. In a Faculty of Medicine, PBL and CM have been applied together as the main learning modes. This provided an opportunity to

Chemistry is regarded as a difficult subject for students. The difficulties may lie in human learning as well as in the intrinsic nature of the subject. Concepts form from our senses by noticing common factors and regularities and by establishing exa

Investigation of students' cognitive structure in elementary genetics through word association tests
Publikováno v:
Journal of Biological Education. 33:134-141
The word association test is one of the commonest and oldest educational tools for investigating the cognitive structure of learners. In this present study, a word association test was used to map the cognitive structure of areas of elementary geneti
