Constructed response (CR) assessments allow students to demonstrate understanding of complex topics and provide teachers with deeper insight into student thinking. Computer scoring models (CSMs) remove the barrier of increased time and effort, making CR more accessible. As CSMs are commonly created using responses from research-intensive colleges…

Extensive research has shown that one of the benefits of programming to learn about scientific phenomena is that it facilitates learning about mechanisms underlying the phenomenon. However, using programming activities in classrooms is associated with costs such as requiring additional time to learn to program or students needing prior experience…

There has been increased recognition in the past decades that model-based inquiry (MBI) is a promising approach for cultivating deep understandings by helping students unite phenomena and underlying mechanisms. Although multiple technology tools have been used to improve the effectiveness of MBI, there are not enough detailed examinations of how…

Model-based reasoning has been introduced as an authentic way of learning science, and many researchers have developed technological tools for learning with models. This paper describes how a model-based tool, "BioLogica"™, was used to facilitate genetics learning in secondary 3-level biology in Singapore. The research team co-designed…

Automated computerized scoring systems (ACSSs) are being increasingly used to analyze text in many educational settings. Nevertheless, the impact of misspelled words (MSW) on scoring accuracy remains to be investigated in many domains, particularly jargon-rich disciplines such as the life sciences. Empirical studies confirm that MSW are a…

This paper describes research on the use of knowledge models (ontologies) for building computer-aided educational software in the field of control engineering. Ontologies are able to represent in the computer a very rich conceptual model of a given domain. This model can be used later for a number of purposes in different software applications. In…

The use of computer simulations as educational tools may afford the means to develop understanding of evolution as a natural, emergent, and decentralized process. However, special consideration of developmental constraints on learning may be necessary when using these technologies. Specifically, the essentialist (biological forms possess an…

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…

Discusses in great detail aspects connected with the visual and mental processing of chemical images. Presents various types of conventions for translating three-dimensional objects into two-dimensional representations. (Author/CCM)

Describes the Virtual Solar System (VSS) course which is one of the first attempts to integrate three-dimensional (3-D) computer modeling as a central component of introductory undergraduate education. Assesses changes in student understanding of astronomy concepts as a result of participating in an experimental introductory astronomy course in…

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

Visualizes the future of learning and considers current and new paradigms concerning technology and learning. Recommends high interactive tutorial learning for very large numbers of students in distance learning situations. (Contains 17 references.) (Author/YDS)

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…

Describes an introductory undergraduate astronomy course in which the large-lecture format was moved to one in which students were immersed in a technologically-rich, inquiry-based, participatory learning environment. Finds that virtual reality can be used effectively in regular undergraduate university courses as a tool through which students can…

Describes a project that explores the combined use of Internet client-server technology and interactive computer modeling software for improving secondary science teaching. Classroom core practices are evaluated for traceable impacts of change in student learning. Contains 59 references. (DDR)
