Throughout the years, scientific research has increasingly aimed to identify students' misconceptions and alternative views regarding fundamental concepts and principles of chemistry. Valuable international bibliographic information was created, including details on teaching density and gaining respondent acceptance. The study aimed to explore…

The introduction of the computer into the educational process is a fact. The educational use of new technologies creates a new, more appealing and enjoyable learning environment. The introduction of new technologies into school differentiates the role of the professor by giving him/her a guiding character in a process of experiential approach to…

Chemical bonding is a fundamental but complex topic, which has traditionally been associated with learning difficulties, misunderstandings, and misconceptions. This paper reviews some previous studies, concerning students' conceptual difficulties and reports the findings from a research study with Greek students, which set out to examine their…

One hundred and thirty Greek primary school teachers participated in a study, where the effectiveness of a specially designed intervention on chemical changes was tested. The study took place in the wider context of an in-service training course where the key feature was an innovative approach based on the concept of a substance and its…

In this study, students' understanding of chemical changes was investigated in relation to four individual differences, related to logical thinking, field dependence/independence, convergence and divergence thinking. The study took place in Greece with the participation of students (n = 374) from three grades (8th, 10th and 12th grades) of…

We present a programme for a novel introductory lower-secondary chemistry course (seventh or eighth grade) that aims at the application of theories of science education, and in particular of conceptual/meaningful learning and of teaching methodology that encourages active and inquiry forms of learning The approach is rigorous with careful use of…

Part 2 of the findings are presented of a quantitative study (n = 125) on basic quantum chemical concepts taught at twelfth grade (age 17-18 years) in Greece. A paper-and-pencil test of fourteen questions was used that were of two kinds: five questions that tested recall of knowledge or application of algorithmic procedures (type-A questions);…

In this study, a close-ended questionnaire examining all aspects of photosynthesis simultaneously has been developed and administered to 290 Greek pupils aged 13. It contains complementary or logically related items that permitted us to assess the understanding of each aspect by carrying out crossanalysis. The main findings are: that pupils are…
