This research examines science-simulation software available for grades 6-12 science courses. The study presented, funded by the National Science Foundation, had two objectives: a literature synthesis and a product review. The literature synthesis examines research findings on grade 6-12 student learning gains and losses using virtual laboratories…

Those who study secondary science teachers are often concerned with preservice or in-service teacher development. Science teacher educators have acknowledged that this focus is limited, as the induction years of beginning teachers are an important component of teacher development. This mixed methods study focuses on the induction years of…

To enhance the learning outcomes achieved by students, learners undertook a computer-simulated activity based on an acid-base titration prior to a university-level chemistry laboratory activity. Students were categorized with respect to their attitudes toward learning. During the laboratory exercise, questions that students asked their assistant…

This multiple case study examined the coauthorship process in research laboratories of different university departments. The study focused on two cases comprising five writing teams, one in biochemistry and microbiology and four in earth and ocean sciences. The role of the research supervisor, the role of the student (graduate and postgraduate),…

This study focuses on the ability of high-school chemistry students, who learn chemistry through the inquiry approach, to ask meaningful and scientifically sound questions. We investigated (a) the ability of students to ask questions related to their observations and findings in an inquiry-type experiment (a practical test) and (b) the ability of…

Activities in 31 Israeli high school biology and 4 college-level laboratories in first and second years of medical school were analyzed using the Classroom Observation Instruments. Percentages of time spent in pre-lab discussion (problem identification, instructions); lab-work (identifying investigation components, responding to students,…

The purpose of this study was to examine the effects of three instructional methods and conceptual systems orientation on achievement in a freshman general chemistry laboratory course. Traditional approach, learning cycle, and computer simulations are discussed. (KR)
