A study compared the teaching behaviors of University of Tel Aviv (Israel) physics and chemistry faculty over two consecutive years, at mid- and end-semester. Findings indicate a high degree of stability in behaviors over time, with no clear-cut improvement during a semester except for faculty undertaking special instructional improvement…

Students explore the workings of the lever, wheel and axle, and the inclined plane as they build simple toys--a bulldozer and a road grader. The project takes four weeks. Diagrams and procedures are included. (PR)

Presents the application of decision-theoretic technique to a computer-based tutoring system for elementary mechanics. Uses sound probabilistic reasoning and a student model to identify learners' misconceptions. Focuses on the integration of Bayesian belief networks, item response theory, decision analysis, and database management systems in…

Describes the objective behind this special issue: to identify a science content area (physics for eighth to eleventh graders), work with science teachers to produce a set of content materials, and present a common content outline to a group of instructional designers. The first article describes the derivation of the content outline. The next…

Discusses the benefits of using multimedia Computer Assisted Learning (CAL) as an alternative teaching method. CAL packages may provide more flexibility in course design, encourage student-centered learning, and help students of differing abilities and academic backgrounds. Also examines problems associated with the use of multimedia CAL such as…

Details an ocean-based lesson and provides background information on the designation of 1998 as the "Year of the Ocean" by the United Nations. Contains activities on the poster insert that can help raise student awareness of coastal-zone hazards. (DDR)

Describes the setup of a system that allows vibrations in two dimensions to demonstrate polarization states of light and particle spin. (WRM)

Recent literature in science education suggests that, to transform girls' participation, learning, and identities within school science, we must think about ways to engage girls in different kinds of educational activities that promote broader meanings of science and scientist. This study was designed to examine more deeply this call for a changed…

This study used case studies from three science teachers to compare three groups of students studying Grade 8 physics using Robolab instead of traditional lab materials. The three teachers represented an English as a second language class, a regular class with many English language learner students, and a Mathematics, Engineering, Science…

Each month, "Curriculum Review" offers teachers mutual support, the sharing of ideas, and words of encouragement to help them face challenges in the classroom. The March 2004 issue of "Curriculum Review" contains the following articles: (1) "We Hear from Readers"; (2) "What They're Saying"; (3) "Technology Update"; (4) "4 Ways to Give Students a…

The relationship between the form and structure of plants and their gravitational environment is one of the most important teaching subjects of biological education. However, the teaching materials for the gravity effect have so long been concerned only with gravitropism, i.e. the short-time response of adjusting the orientation of seedling roots…

We examined the beliefs about science teaching and learning held by elementary preservice teachers in a science methods course, comparing students who had experienced an inquiry-based physics course with those who had not. Students who had taken the physics course prior to the methods semester were better equipped to recognize and learn from…

In this paper I examine the phenomenon of university teachers as researchers in their own classrooms. I use examples of three research teams in which we studied: (1) student response to a science and society course; (2) teacher and student perceptions of inquiry in a physics course; and (3) teaching and learning about the nature of science in an…

The issue of unfairness arises in high-stakes public examinations when students choose questions from alternatives that are offered and marks on the alternatives turn out to be discrepant. This paper addresses and defines unfairness and discrepancy in the context of alternative questions in Physics Tertiary Entrance Examinations (TEE) in Western…

In this era of dramatically increased astronomy education research efforts, there is a growing need for standardized evaluation protocols and a strategy to assess both student comprehension of fundamental concepts and the success of innovative instructional interventions. Of the many topics that could be taught in an introductory astronomy course,…
