Online homework systems have been shown to help student achievement in chemistry courses. This study sought to compare the levels of knowledge retention in students over the course of a semester, using two different types of homework systems--the adaptive-responsive system and the traditional-responsive system. Two sections of a first semester…

The goal of this study was to investigate the timing of online homework completion and its effects on student performance. Data was collected from two large, first-semester general chemistry sections at a southwestern university. Specifically, this study aims to explore the link between when students complete their homework relative to the date…

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…

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)

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…

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…

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…

Explores the efficacy of promoting a beginning chemistry teacher's curriculum development and teaching practices through the use of computers. Observes and analyzes the teacher's instructional practices both before and after the web site treatment which includes pictorial analogies, historical cases of science, and discrepant events. Reports…

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…

Describes a course for non-chemistry majors that uses a distance-education format. Utilizes lectures on videotape, electronic communication, thematic research assignments, and take-home lab projects. (DDR)

Illustrates the development of multimedia courseware such as CHEMMAT. Discusses the features of the courseware including adaptability, use of the teacher module, use of graphics and video clips, and the ease of customizing the content in various languages. (DDR)
