When solving a scientific problem through experimentation, students may have the responsibility to design the experiment. When students work in a conventional condition, with paper and pencil, the designed procedures stay at a very general level. There is a need for additional scaffolds to help the students perform this complex task. We propose a…

From a theoretical viewpoint, educational interfaces that facilitate communicative actions involving representations central to a domain can maximize students' effort associated with constructing new schemas. In addition, interfaces that minimize working memory demands due to the interface per se, for example by mimicking existing non-digital work…

Many students experience difficulties in solving applied physics problems. Most programs that want students to improve problem-solving skills are concerned with the development of content knowledge. Physhint is an example of a student-controlled computer program that supports students in developing their strategic knowledge in combination with…

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…

Suggests that, based on a theory of situated learning, assessment must emphasize process as much as product. Several assessment examples are given, including a computer-based planning assistant for a mathematics and science video, suggestions for computer-based portfolio assessment, and speculations about embedded assessment of virtual situations.…

Reports on the application of technology in elementary and secondary education. The report is based on a review of the research literature and on written submissions and oral briefings from a number of academic and industrial researchers, practicing educators, software developers, and government agencies.

Presents an interactive, case-based online network (ICON) that provides a learning environment that integrates student thinking across different concentration tracks and allows students to get away from interpreting vast amounts of available information, move toward selecting useful information, recognize discriminating findings, and build a…

Explores the potential of the RAY learning environment in improving learning about optics. Results indicate that this environment, which includes a flexible ray-tracing simulation, had a significant effect on the spontaneous and correct use of the model by students in solving problems and a limited effect on conceptual understanding, but promoted…

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…

Gives descriptions of how performance assessment tasks are linked to science curriculum objectives, along with criteria for and examples of performance assessment tasks. Describes the role that computers and related technology can play in problem-based performance assessment. (LZ)
