Study of Conceptual Knowledge and Mode of Reasoning Relating to the Characteristics of Covalent Bonds in Future Algerian Physics Teachers

Pubblicato online: 27 May 2022
Pagine: -

Astratto

Abstract

In this study we tried to analyse how future teachers of Ecole Normale Supérieure (ENS) school who are at the end of education have integrated the specifications of covalent bonds in the different bond orders in terms of symmetry, stability, length, localisation (in the case of structures of ethane, ethylene and acetylene) or delocalisation of electrons (case of benzene). The analysis of responses to a written questionnaire shows that the majority of students have only integrated some knowledge, which may be termed as procedural, on the structural elements of molecules such as stability and the length of bonds. Although possessing some conceptual knowledge, students tend to use an alternative way of reasoning arising from the mental representation that single and multiple bonds are independent entities: the single bond is a “σ bond” while the double bond is considered only as a “π bond”.

Congruence and Discrepancy Between Observation and Teachers’ Self-Report of Inquiry-Based Instruction

Pubblicato online: 27 May 2022
Pagine: -

Astratto

Abstract

Opportunities for self-reflection and collaborative reflection support inquiry-based teaching. The presented study focuses on retrospective self-reports of 14 science teachers about teaching inquiry lessons in their regular science classes. Their self-reports were compared with observation reports of researchers. Data from semi-structured interviews were added. The results indicate that teachers overestimated their performance in the class in all observed areas of inquiry instruction. The most misinterpreted and overestimated area by teachers seems to be formulating research questions, analysing data and drawing conclusions, which are the most effective processes in student learning. Based on the results of the study, several implications are suggested in order to focus on the self-reflective skills of teachers.
