Classroom discourse can affect various aspects of student learning in science. The present study examines interactions between classroom discourse, specifically teacher questioning, and related student cognitive engagement in middle school science. Observations were conducted throughout the school year in 10 middle school science classrooms using…

Physics teachers are most effective when their students are active learners who think and participate in every class. This extends beyond the classroom too: ideally, students would tackle challenging questions and exercises after every class--not just before the exam or the night before the weekly homework is due. Just-in-Time-Teaching was…

Designed-based research principles guided the study of 51 secondary-science teachers in the second year of a 3-year professional development project. The project entailed the creation of student-centered, inquiry-based, science, video games. A professional development model appropriate for infusing innovative technologies into standards-based…

This paper describes the use of handheld computers in the Science classrooms of four Tasmanian schools over a year. Analysis was informed by theories of innovation and assisted by ecological perspectives. Teachers demonstrated a range of attitudes to innovative pedagogies associated with the devices, and these corresponded to student achievements.…

From the diversity of views on the role of information and communications technology (ICT) in education, this article focuses on ICT as a tool for enhancing learning in the subject-defined context. Drawing from evidence gathered from teachers' evaluations of over 300 lessons taught using ICT, we examine the implementation strategies and teacher…

Purpose: The purpose of this paper is to critically examine an assessment task, undertaken by pre-service science teachers, that integrates the use of technology (in this case digital video-recorders and video-editing software) whilst scaffolding skill development. The embedding of technology into the assessment task is purposeful, aiming to…

This paper describes an inservice project designed by The Johns Hopkins University and the Baltimore City Public School System to help teachers acquire the skills necessary to effectively integrate computer technology into science instruction. From 1986 to 1988 the project was implemented in the large urban Baltimore school system with 100…
