Between 1880 and 1920 the way science was taught in American High Schools changed dramatically. The old "lecture/demonstration" method, where information was presented to essentially passive students, was replaced by the "laboratory" method, where students performed their own experiments in specially constructed student laboratories. National…

Many studies have stressed students' lack of understanding of experiments in laboratories. Some researchers suggest that if students design all or parts of entire experiment, as part of an inquiry-based approach, it would overcome certain difficulties. It requires that a procedure be written for experimental design. The aim of this paper is to…

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…

The aim of this paper is to consider some issues in the historical international development of science education making comparisons between the educational systems of Britain and the United States of America. The author's particular interest relates to the role of the textbook in science education, so this is area on which this study will…

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,…

This experiment was designed to help students improve the critical thinking skills that are required to analyze and discuss the results of an organic chemistry experiment in an effective manner. The initial objective indicated in the prelab handout for this puzzle experiment was the synthesis of methyl 4-bromobenzoate using the Fischer…

Inquiry-based laboratories are acknowledged as the preferred method of instruction for development of research skills. Much has been written about changes in student performance associated with inquiry, but less is known about how students view the inquiry-based format or whether they perceive a benefit from this type of instruction. The Student…
