Using visual models is common in science and should become more common in classrooms. Our research group has developed and completed studies on the use of a visual modeling tool, the Concept Connector. This modeling tool consists of an online concept mapping Java applet that has automatic scoring functions we refer to as Robograder. The Concept…

This paper reports on the level of effectiveness of the various course elements (such as electronic homework, written homework, collaborative group problems and class participation) in calculus-based introductory Newtonian mechanics as taught to Massachusetts Institute of Technology (MIT) students. Effectiveness is measured by the regression…

Examines student success in a freshman chemistry course that involves students who are at risk of failure. (Contains 14 references.) (YDS)

Uses the World Wide Web to provide an active learning environment with rapid and accurate homework feedback which is also an effective tool to foster critical thinking skills. Allows students to submit a second chance homework following feedback to a previously wrongly answered question. (YDS)

This digest presents information for parents regarding science and math homework. The benefits of homework are discussed and guidelines for gauging the amount of time spent on homework are given. Suggestions for family policies and procedures for helping children complete homework assignments are also presented. (WRM)

Describes the development and implementation of a web-based software engine that selects from a database of questions for students to answer and provides immediate feedback for students and instructor. Discusses the results of using this technology in an organic chemistry section. (Contains 22 references.) (WRM)

This digest presents an overview of ways that parents can encourage their child's learning in science. National and state standards for science knowledge and skills are discussed. The importance of parental guidance and encouragement in all subjects--science in particular--is also discussed. Suggestions are made for setting a good example, helping…

Describes a study of three parts: (1) the application of a statistical technique for predicting performance; (2) a computer program for teaching basic problem-solving skills; and (3) evidence for the value of teaching with complex homework problems in an introductory physics course required for engineering majors. (Contains 42 references.)…

Emerging applications of microcomputers and hypermedia to assessment in science education are reviewed. Although the current use of technology consists mainly of computerized administration of multiple choice tests drawn from item banks, the potential advantages are much greater. Among these advantages are immediate feedback to students, formative…
