Pre-laboratory work has been shown to be an effective investment at undergraduate level in chemistry at the University of Bristol. A Dynamic Laboratory Manual (DLM) has been developed to allow undergraduate students to rehearse practicals using virtual experiments, video clips and a range of assessment support. The DLM has been shown to be highly…

This paper outlines several benchtop nanoscale patterning experiments that can be incorporated into undergraduate laboratories or advanced high school chemistry curricula. The experiments, supplemented by an online video lab manual, are based on soft lithographic techniques such as replica molding, micro-molding in capillaries, and micro-contact…

For distance-education students, the requirement for a laboratory course can present a significant hurdle to completing degree requirements. To better serve these nontraditional students, the authors developed a distance version of the laboratory course to provide a hands-on experience similar to that of on-campus students. In order to make the…

The purpose of this study was to understand one case of undergraduate inquiry-based instruction through the words and actions of students and instructors. The data sources included fieldnotes from 16 of 29 classes, two sets of student and instructor interviews (beginning and end of the semester), and a collection of artifacts, such as the…

Conventional physics laboratory courses generally include an emphasis on increasing students' ability to carry out data analysis according to scientific practice, in particular, those aspects that relate to measurement uncertainty. This study evaluates the efficacy of the conventional approach by analyzing the understanding of measurement of…

Many plant biologists claim that there is a tremendous bias towards the study of animals in science curricula, however, there is even less attention given to topics on fungi. On average, Biology laboratory manuals will have only one fungi exercise, and most of the time, it is mainly descriptive. As we developed this exercise we realized how much…

Although electronic instructional media are becoming increasingly prevalent in science classrooms, their worth remains unproven. Here, student perceptions and performance using CD-ROM delivery of lab materials are assessed. Numerous learning barriers that produced lower lab grades for students using a CD-ROM lab manual in comparison to a print…

Chromatography is a process by which mixtures can be separated or substances can be purified. Biological and chemical laboratories use many different types of chromatographic processes. For example, the pharmaceutical industry uses chromatographic techniques to purify drugs, medical labs use them to identify blood components such as cholesterol,…

Examines the treatment of errors and significant figures in physics manuals as part of an evaluation of these instructional materials. Comments on specific materials reviewed are provided. (JN)

Content, readability, safety aspects, appearance, technique, effectiveness of experiments, enrichment exercises, teacher aids, and special features of 12 physics laboratory manuals are reported and compared. (JN)

This column generally relates errors which have been discovered in textbooks. The error discussed in this issue is the prevalence of erroneous ideas in organic chemistry textbooks, related to the chemistry of sodium borohydride. (Author/SA)

Analyzes nine high school biology manuals to determine how well they promote the basic and integrated science process skills that are involved in scientific inquiry. Results indicate that the manuals seldom enable students to use their knowledge and experience to pose questions, solve problems, investigate natural phenomena, or construct answers…

Professors have long assigned to their students works of which they were the author. The practice ranges from assigning commercially published textbooks they have written to having students buy a volume they have written and published or course packs made up of their own materials they have photocopied. Not only individual professors, but also…

Presents the philosophy and mechanics of a professionally oriented astronomy laboratory for nonscience majors. Design of the laboratory, description of the exercises, and the results of using this approach at the University of Kansas are also described. (HM)

Compares a broad cross-section of high school biology laboratory manuals with respect to several standard features as well as the degree to which they engage students in scientific inquiry. Discusses comparisons with respect to topics contained in the manuals, types of activities, lab exercises, and features of activities. (JRH)
