Following this, Taber (2001) proposed a teaching sequence alternative to those available in existing curriculum documents and textbooks. He proposed that teaching be started from metallic structure to ionic structure, then giant covalent structure and finally simple molecular structure. During teaching, teachers should be cautioned about the use of language, the undue emphasis on the role of atoms (atomic ontology), the explication of the nature of bonding (based on electrostatic forces rather than electron transfer or sharing), and a better integration of the relationship between bonding and structure. In relation to the literature about scientific modelling, bonding should be taught as an 'explanation' of properties of chemicals, rather than a mere 'description' of structure. This paper reports an empirical study of a class of Year 10 students' learning outcomes based on the proposed teaching sequence and emphases. Throughout the learning of the topic 'chemical bonding' which spanned two months, three students ranged from the highest to medium achieving students in the class were selected for interviews. Each student was interviewed on four separate occasions in the course of their learning of 'chemical bonding'. Their understanding of concepts in relation to chemical bonding was probed through their verbal and visual representations. The effectiveness of the teaching sequence was evaluated in the light the alternative conceptions reported in the literature, strategy and suggestions for further improvements were discussed.

The aim of this study was to investigate how an experienced chemistry teacher gains and refines her pedagogical content knowledge (PCK) by cooperating with two grade 12 students (age 18) as coteachers while teaching chemical bonding in a grade 10 Upper secondary class. The study has been conducted from a sociocultural perspective, especially Vygotsky’s zone of proximal development (ZPD) (Vygotsky, 1978). Other theoretical concepts and models that has framed this study are Shulman´s Pedagogical content knowledge (PCK) and Pedagogical reasoning and action model (Shulman, 1986, 1987). When analysing the data, Magnusson, Krajcik, and Borko´s (1999) model of PCK and the 2017 Refined consensus model of PCK (Carlson, Daehler, et al., in press) was used. Empirical data was collected by video- and audio recorded lessons, coreflection sessions, coplanning sessions and interviews. During 10 weeks, about 28 hours of video and audio recordings was collected. Selected parts of the material were transcribed and analysed in order to answer two questions: (1) How can chemistry teachers refine their PCK when coteaching together with senior students in an Upper secondary science class? (2) How do Upper secondary senior student coteachers´ conceptual knowledge of representations and chemical bonding shape a teacher’s foundation of personal PCK (pPCK) when teaching chemical bonding in an Upper secondary science class? The results relating to research question one indicates that the coteachers contributed with their own learning experiences to help the teacher understand how students perceive difficult concepts. The coteachers were mediating between the teacher and the students, thus bridging the gap between the teacher and the students’ frames of references. The experienced chemistry teacher improved her understanding of students´ thinking about themselves as learners of chemical bonding. Regarding the second research question, the findings showed that the creative process of reconstructing concepts of chemical bonding in the coplanning sessions meant that these were a useful tool for developing new teaching strategies and to further develop representations such as drama to illustrate chemical bonding. Together, the teacher and student coteachers, constructed a new representation that better illustrated polar covalent bonding. Taken together, these results provide important insights into how the chemistry teacher´s pPCK was refined and how the coteachers contributed to improve instructional strategies.

This book examines the effect of using molecular models on students' understanding of structure and chemical bonding in selected high schools in Kenya.The study is a published thesis submitted in partial fulfilment of the requirements for the award of the degree of Master of Science in Science education of Masinde Muliro University of Science nd technology, Kenya.In a nutshell, the study found that using molecular models in classroom instruction significantly promoted students' understanding of structure and bonding, an otherwise abstract topic in chemistry. The study recommended integration of novel information technology approaches- particularly computer-based ones- in classroom instruction. Further, science teachers are encouraged to carefully consider, select and use instructional approaches that cna be described as "non-traditional." It is hoped that readers will find this book thought-provoking and that it will prompt a review of approaches to teaching other abstract topics in chemistry.
