Korpershoek, Hanke; Kuyper, Hans; van der Werf, Greetje – International Journal of Science and Mathematics Education, 2015
Word problems are math- or science-related problems presented in the context of a story or real-life scenario. Literature suggests that, to solve these problems, advanced reading skills are required, in addition to content-related skills in, for example, mathematics. In the present study, we investigated the relation between students' reading…

Padilla, Kira; Van Driel, Jan – Chemistry Education Research and Practice, 2011
The purpose of this paper is to capture the pedagogical content knowledge (PCK) of university professors about quantum chemistry. More specifically, we aimed to identify and analyze relationships between specific PCK components, using an adapted version of the model of PCK of Magnusson "et al.". A sample of university professors (n = 6)…

Why and How We Made a Problem Oriented AV Teaching Unit for Chemistry Students.
Peer reviewed Peer reviewed
Mulder, T. H. M.; Verdonk, A. H. – Journal of Educational Television, 1984
Describes an audiovisual teaching unit on the chemical laboratory technique of recrystallization which was developed along problem-solving lines and based on observation of student laboratory behavior. Discussion includes usual procedures for developing such units, how this unit solves problems typically associated with teaching, and its general…

Recurrent Difficulties: Solving Quantitative Problems.
Peer reviewed Peer reviewed
Kramers-Pals, H.; And Others – Journal of Chemical Education, 1982
Difficulties encountered by students when solving problems were examined using Program of Actions and Methods (PAM) for systematic problem solving in science. Difficulties encountered included those in analyzing the problem, planning the problem-solving process, executing routine operations, and those related to the ways teachers solve problems.…
