tandfonline.com – The drama of chemistry – supporting student explorations of electronegativity and chemical bonding through creative drama in upper secondary school

tandfonline.com har udgivet en rapport under søgningen “Teacher Education Mathematics”: ABSTRACT ABSTRACT Getting students to understand the particulate nature of matter is a major challenge for chemistry education. In upper secondary school students commonly struggle to distinguish between intra- and intermolecular bonding and analyse chemical bonding in terms of electronegativity. In this study, we explore how creative drama may be used in chemistry education to facilitate students’ explorations of electronegativity and chemical bonding in Swedish upper secondary chemistry education. The study was conducted as a design-based intervention in three cycles in two schools. The interventions (which lasted for 30–60 minutes) were single-lesson-interventions consisting of drama activities and discussions in whole-class and student groups. A qualitative content analysis produced themes that captured the ways in which the students explored electronegativity and… Continue Reading

tandfonline.com – Coteaching with senior students – a way to refine teachers’ PCK for teaching chemical bonding in upper secondary school

tandfonline.com har udgivet en rapport under søgningen “Teacher Education Mathematics”: ABSTRACT ABSTRACT During the last decade there has been on-going discussions about students’ declining interest and low achievement in science. One of the reasons suggested for this decline is that teachers and students have different frames of reference, whereby teachers sometimes communicate science in the classroom in a way that is not accessible to the students. There is a lack of research investigating the effects of coteaching with senior students in science in upper secondary schools. To improve teaching and to narrow the gap between teachers’ and students’ different frames of references, this study investigates how an experienced chemistry teacher gains and refines her pedagogical content knowledge (PCK) by cooperating with two grade 12 students (age 18) as coteachers. The… Continue Reading
