This study investigated the organizational impact of computer technology on four secondary science teachers' teaching actions using the construct of community of practice. The organizational impact of computer technology refers to teachers' styles and creativity in constructing personally pertinent individual models of teaching when using computer…

In this paper we report on an activity sequence with a group of 29 pre-service physics teachers based on the reconstruction and analysis of a thought experiment that was crucial for Huygens' derivation of the formula for the centre of oscillation of a physical pendulum. The sequence starts with student teachers approaching the historical…

This qualitative case study describes (a) the ways 3D visualization, coupled with other science and literacy experiences, supported young children's first exploration of the Earth-Sun-Moon system and (b) the perspectives of classroom teachers and children on using 3D visualization. We created three interactive 3D software modules that simulate day…

The purpose of this study is to investigate student interactions with simulations, and teacher support of those interactions, within naturalistic high school physics classroom settings. This study focuses on data from two lesson sequences that were conducted in several physics classrooms. The lesson sequences were conducted in a whole class…

This volume presents a compilation and review of more than 400 research studies on science teaching and the preparation of science teachers that were reported in 1988, organized into 10 sections. The sections are: (1) "Professional Concerns"; (2) "Teacher Education"; (3)"Programs"; (4) "Curriculum"; (5)…
