There has been increased attention recently on models and modelling within the global science education field. Research has begun to skew towards a competence-based perspective of models and modelling, as teachers are experiencing challenges and do not have the required competence in modelling from either theoretical or practical perspectives.…

In teaching sciences, models are often used to introduce, elaborate or simplify real-world phenomena or concepts. It is, however, often the case that misconceptions arise from or are facilitated by these teaching models during their transition to mental models of the individual learners. For instance, models are often seen as direct replicas of…

The aim of this study was to examine the potential impact of the representational characteristics of models and students' educational levels on students' views of scientific models and modeling (VSMM). An online multimedia questionnaire was designed to address three major aspects of VSMM, namely the "nature of models," the "nature…

Inquiry- and context-based teaching strategies have been proven to stimulate and motivate students' interests in learning science. In this study, 12 teachers reflected on these strategies after using them in primary schools. The teachers participated in a continuous professional development (CPD) programme. During the programme, they were also…

Large enrolment science courses play a significant role in educating undergraduate students. The discourse in these classes usually involves an instructor lecturing with little or no student participation, despite calls from current science education reform documents to elicit and utilize students' ideas in teaching. In this study, we used the 5E…

Internationally there is concern that many science teachers do not address socioscientific issues (SSI) in their classrooms, particularly those that are controversial. However with increasingly complex, science-based dilemmas being presented to society, such as cloning, genetic screening, alternative fuels, reproductive technologies and…

Models are important both in the development of physics itself and in teaching physics. Historically, the consensus models of physics have come to embody particular ontological assumptions and epistemological commitments. Educators have generally assumed that the consensus models of physics, which have stood the test of time, will also work well…

We investigated the pedagogical content knowledge (PCK) of nine experienced chemistry teachers. The teachers took part in a teacher training course on students' difficulties and the use of models in teaching acid-base chemistry, electrochemistry, and redox reactions. Two years after the course, the teachers were interviewed about their PCK of (1)…

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 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…

In this paper, we present a case study of a beginning chemistry teacher who enrolled in a project aimed to contribute to the development of teachers' knowledge of models and modelling in science. The project consisted of a series of institutional meetings in combination with an action research project the teacher conducted in her own classes. By…

Describes the development of the practices and perspectives of one elementary school teacher as she engaged in teacher-as-researcher methodology in both urban and suburban settings. Documents how the teacher-as-researcher began to explore science inquiry in an elementary setting and how students, parents, and educators became co-learners,…

Reports on learning when engaged in a four-month experience of co-teaching a water unit in a seventh-grade classroom. Suggests that co-teaching allows for a mode of learning that is not captured by Schon's notions of reflection-in-practice and reflection-on-practice. Concludes that co-teaching, as co-learning, is praxis. Contains 26 references.…

Advocates co-teaching as an essential component of teacher education programs. Describes the co-teaching efforts of a university professor, doctoral student, and student-teacher as they taught science to African-American students placed in a low-track program of study in an urban high school. Presents theoretical frameworks associated with…
