Describes a multimedia course in engineering developed to serve course materials to students in a more realistic form so that they will better understand the relevance of the material. Defines multimedia, discusses the advantages of multimedia presentation of course material, and provides details of the tools used in this project. (DDR)

This study compared the achievement of biology, physics, and chemistry students in Higher Level (HL) International Baccalaureate (IB) programs with achievement of students in Subsidiary Level (SL) IB programs and regular Alberta (Canada) programs (n=708 students). Students in IB out-performed students in regular programs. Within IB, HL and SL…

Defines an exploratory lab as consisting of a series of hands-on, qualitative activities that are safe, simple, and inexpensive, use readily available supplies, and illustrate a concept being studied concurrently in the course. Summarizes the results of four years of testing the exploratory program. (DDR)

Describes a titrator system, constructed from a computer-interfaced pH-meter, that was designed to increase student involvement in the process. Combines automatic data collection with real-time graphical display and interactive controls to focus attention on the process rather than on bits of data. Improves understanding of concepts and…

Describes an activity that demonstrates among the following: diffusion; cohesion and adhesion; properties of surface tension which include wicking, hydrophilic, and hydrophobic molecular behaviors; and break up of fat clusters by liquid dishwashing detergent. (DDR)

Describes the development of a chemistry lecture course called CHEMnet that is available via the internet and optimizes multimedia learning environments. Investigates the use and efficiency of multimedia teaching and learning software with CHEMnet. Discusses the structure and features of CHEMnet along with numbers and characteristics of its use.…

Reports a mismatch between teacher and pupil knowledge of acid-base chemistry as a result of controversial episodes from three science lessons. Suggests that the teacher's knowledge is guided by textbook information while the pupil's knowledge is based on direct experimental experience. Proposes that classroom activities should support the…

Describes the weekend science workshop on enzymes and includes several projects that involve students directly, parts of which can be incorporated into a traditional chemistry, biology, or physical science course at the secondary level. Subjects include catalysts and catalytic converters in cars, enzymes as consumer products and in industrial…

Describes the use of supplemental instruction in an introductory chemistry course designed for freshman nursing students and explores its impact on student performance and response to the program. Results indicate a positive impact of supplemental instruction and its popularity with students. Contains 22 references. (JRH)

Presents an alternative approach to teaching laboratory chemistry that considers issues such as safety, waste disposal, and cost. Focuses on the micro-scale approach and discusses a number of positive benefits that can be gained from adopting this approach. (DDR)

Explores the effects of an integrated video media curriculum enhancement on students' achievement and attitudes in a high school chemistry course. Findings reveal significantly higher achievement scores for students who experienced the course enhanced with integrated video media. Students with high levels of logical thinking ability benefited most…

Investigates the effects of computer-assisted instruction (CAI) using molecular-level animation and worksheets upon student achievement, conceptual understanding, and learning motivation. Administers the Patterns of Adaptive Learning Survey (PALS) as a covariate in the study. (Contains 19 references.) (Author/YDS)

An approach which may be useful for teaching electrochemistry in freshman college chemistry courses is presented. Discussed are the potential problems with teaching this subject and solutions provided by this approach. (CW)

Experiments designed to help undergraduate students gain experience operating instruments and interpreting gas chromatography and mass spectrometry data are presented. Experimental reagents, procedures, analysis, and probable results are discussed. (CW)

Discussed are the procedures and results involved in this activity. Student results in undergraduate laboratories indicate high quality results and relative ease of the analysis. (CW)
