Investigates reasoning strategies students use in solving stoichiometric problems and explores the relation between these strategies and alternative conceptions, prior knowledge, and cognitive variables. Results show how stoichiometric relations produce conflicting situations for students leading to conceptual misunderstanding of certain concepts.…

Presents samples of game-display board activities designed for junior high science classes. Employs ideas from traditional seatwork and end-of-chapter exercises such as matching, multiple choice, word puzzles, and summary tables. Activities require a vertical magnetic white board and magnetic word and picture cards. Facilitates classroom…

Examines the perception and knowledge of 205 adults regarding issues related to science and technology. Results indicate that some adults are not well informed about science and technology, major differences exist among respondents on the basis of gender, and there exists a lack of knowledge about certain aspects of elementary science. (Author/JRH)

Explores the training of science teachers at the Northwest Normal University in Lanzhou, China, and its affiliated primary and secondary schools. Discusses strengths and problems of the programs. (Author/JRH)

Discusses problems that students of science face in terms of career options. Argues for the need for cross-training to increase respect between those who do and those who don't do science. (JRH)

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…

Highlights the need to reinvigorate chemistry education by means of the visual-spatial approach, an approach wholly in conformance with the way modern chemistry is thought about and practiced. Discusses the changing world, multiple intelligences, imagery, chemistry's pictorial language, and perceptions in chemistry. Presents suggestions on how to…

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…

Reviews all netcourses for teachers in mathematics and science, highlights the advantages of netcourses, and discusses the differences between conventional and network-based courses. Uses this analysis to predict the early emergence of netcourses for the professional development of teachers. (12 references) (JRH)

Discusses the use of computer-aided instruction (CAI) packages in promoting active student learning. Describes the development of a CAI package that highlights discussion of real engineering cases and students' ability to transfer knowledge to new engineering problems. Concludes that the students' problem-solving skills can be improved with the…

Attempts to identify variables for predicting academic success in electronics and find a model for predicting success in each of three main types of electronics programs. Results indicate that student's success in math and science in high school is a good predictor of their success and abstract learning preference is a valid discriminator between…

Presents a qualitative case study of the Technology Enhanced Secondary Science Instruction (TESSI) model. Reports that its implementation resulted in significant changes in the educational beliefs and the teaching and learning practices of those involved. Illustrates these changes through reflections by the teachers, students, administrators, and…

Describes a project whereby students collect morphological and anatomical measurements concerning the response of pine to elevated levels of ozone. Suggests that student measurements represent a reliable source of data for scientists. Presents examples of student datasets and comparisons with reflectance data. Discusses the importance of being…

Introduces general features of distance learning and examines essential aspects of instructional design for distance learning with special emphasis on instructional design methodologies and media selection. Discusses the ACTIONS Model (Access Costs Teaching Interaction Organization Novelty Speed). (56 references) (Author/JRH)

Raises a number of equity challenges for distance learning educators centering around who is taught, what is taught, and how the teaching is done. Suggests a series of recommendations that educators can implement to make distance learning a leader in increasing educational equity for all students. (42 references) (Author/JRH)
