Compares the effects of using two- and three-dimensional model representations of molecular structures on student learning of organic chemical structures. Reports that students using both three-dimensional computer models and ball-and-stick models scored higher on the three-dimensional retention test of isomeric identification but lower on a…

Investigates the effect of Pen-Point and Powerbook computers on solving a multiple-step chemistry problem among white, Afro-American, and Hispanic students. Results suggest that the Pen-Point computer has a more positive effect on the problem- solving performance and attitude of students towards computers than the Powerbook computer. Contains 14…

Presents key points of an on-line conference discussion and integrates them with information from the literature. Key points included: computer as a tool for learning, study, research, and communication; hardware, software, computing concepts, and other teaching concerns; and the appropriate place for chemistry computer-usage instruction. (45…

Describes the ongoing curriculum development efforts of the Consortium for the Application of Space Data in Education (CASDE), an evolving consortium of educators, engineers, scientists, and other professionals dedicated to providing the educational community with vast amounts of NASA imagery, tools, and interdisciplinary learning activities via…

Explores evolutionary changes in students' (n=46) motion-related language mediated by computer-based Newtonian microworlds. Documents how ways of talking emerge and how the convergence of meaning arises from the affordances provided by the interpretive flexibility of the microworld, conversations with the teacher, and the microworld which assures…

Examines the relationship between computer use and students' science achievement based on the data from the Program for International Student Assessment (PISA). Results show that it is not computer use itself that has a positive or negative effect on the science achievement of students, but the way in which computers are used. (Author/SOE)

Examines the relative effectiveness of guided versus unguided computer-based instruction with regard to regular instruction in improving content knowledge and process skills among students with low and high chemistry achievement levels. The effectiveness of computer-based instruction increases when learning is supported by teacher-directed…

Introduces the two-week Summer Science and Math Experience program developed for high school minority students which provides the opportunity for access to a laptop computer for personal use during both the summer and the academic year. (Author/YDS)

Presents a model for using the Internet to teach high school students about plasma physics and fusion energy. (Author/CCM)

Attempts to validate the use of microcomputer-based laboratories for the teaching of physics on both theoretical and empirical grounds. Includes a laboratory that addresses the voltage-current characteristics of several components. (Author/MM)

Reports on the evaluation of an interactive media-based science-education project. Concludes that a number of factors must come together for project success, including an environment conducive to innovation and development and strong administrative interest. Contains 16 references. (DDR)

Enumerates concerns that educators have regarding the use of student data-collection tools such as the computer-based laboratory (CBL) and the microcomputer-based laboratory (MBL). Compares various types of data-collection technologies. (DDR)

Describes the development of a chemistry lecture course called CHEMnet that is available via the internet and optimizes multimedia learning environments. Investigates the use and efficiency of multimedia teaching and learning software with CHEMnet. Discusses the structure and features of CHEMnet along with numbers and characteristics of its use.…

Describes the design of a Common Molecules collection that provides interactive tools for 3-D visualization of molecules. The organizational design provides not only structural information, but also historical and/or key information on the properties of the molecules in the collection. Describes student use of the collection and the role of…

Describes the design of several CD-ROMs with different strategies and foci for teaching general chemistry with large databases of visual information. Presents a sample search with a CD-ROM. Discusses teacher resources including animations, visual databases for presentations, demonstration manuals, laboratory manuals, and encyclopedias as well as…
