Baptista, Monica; Martins, Iva; Conceiçao, Teresa; Reis, Pedro – Chemistry Education Research and Practice, 2019
The purpose of this study was to understand how the use of multiple representations (MR), during a sequence of lessons on the saponification reaction, can help students develop their cognitive structures. We examined (i) the effect of the teaching sequence with MR on the development of the students' cognitive structures and (ii) how, according to…

Scherer, Ronny; Tiemann, Rudiger – Computers & Education, 2012
The ability to solve complex scientific problems is regarded as one of the key competencies in science education. Until now, research on problem solving focused on the relationship between analytical and complex problem solving, but rarely took into account the structure of problem-solving processes and metacognitive aspects. This paper,…

Harrison, Allan G.; De Jong, Onno – Journal of Research in Science Teaching, 2005
This study describes the multiple analogical models used to introduce and teach Grade 12 chemical equilibrium. We examine the teacher's reasons for using models, explain each model's development during the lessons, and analyze the understandings students derived from the models. A case study approach was used and the data were drawn from the…
