This study investigated the effects of 5E instructional model on the teaching processes of novice teachers. First, we conducted a teaching design training project based on the 5E model for 40 novice teachers, and compared pre-texts of the teachers' teaching process from before the training with post-texts obtained immediately following the…

This study explored how students visualise the states and classifications of matter with the use of scientific models. Misconceptions of students in using scientific models were also identified to formulate a teaching framework. To elicit data in the study, a Visual Conception Questionnaire was administered to thirty-four (34), firstyear, general…

We present quantitative results for the doctoral thesis of the first-named author of this article. The objective was to recommend and test a teaching proposal for core knowledge of evolutionary biology in secondary education. The focus of the study is "Problem cores in teaching". The "Weaving evolutionary thinking" teaching…

This study examined the effectiveness of Argument-Driven Inquiry (ADI) as an instructional model in a general chemistry laboratory course. The study was conducted over the course of ten experimental sessions with 125 pre-service science teachers. The participants' level of reflective thinking about the ADI activities, changes in their science…

A case is described of the development of a lesson plan for 10th grade (age range 15-16) chemistry classes on the chemistry of shower gels. The lesson plan follows a socio-critical and problem-oriented approach to chemistry teaching. This means that, aside from learning about the basic chemistry of the components making up modern shower gels in…

As teachers' knowledge determines to a large extent how they respond to educational innovation, it is necessary for innovators to take this knowledge into account when implementing educational changes. This study aimed at identifying patterns in the content and the structure of science teachers' knowledge, at a point in time when they still had…

The purpose of this paper was to investigate students' views on models and modelling in science as well as the role that models play in learning, using a theoretical framework of models in learning. Students' views on models in science were investigated using a pencil-and-paper questionnaire given to 275 students from Grade 8 (13 years old) to…

The purpose of the study was to investigate secondary students' understanding of the descriptive and predictive nature of teaching models used in representing compounds in introductory organic chemistry. Of interest were the relationships between teaching models, scientific models, and students' mental models and expressed models. The results from…

International specialized literature focused on research in biology education is sadly scarce, especially regarding biochemical and molecular aspects. In this light, researchers from this Centre for Structural Molecular Biotechnology developed and evaluated a three-dimensional educational model named "Building Life Molecules DNA and RNA." The…

Describes a teaching model aimed at promoting conceptual change concerning heat and temperature. The model is used with teachers (n=2) and students (n=92) to explore its use as a professional development tool as well as a teaching strategy. Results indicate that the teaching model is effective in changing students' ideas and the approach resulted…

This study examined the effects of a Web site design project on students' motivation and achievement. Tenth-grade biology students worked together in teams on an ecology project that required them to locate relevant information on the Internet, decide which information should be included on their Web site, organize the information into Web pages,…
