Students learn science best with activities that mirror the way scientists work. This article describes how geologists investigate groundwater flow systems in areas of karst topography--geologic formations shaped by dissolving bedrock--and provides a way for students to replicate this research. Students also use electric current to model water…

The topics of nature, for example semiochemicals, are motivating topics, which can be used to teach organic chemistry at high school level. The history, classifications, a few important applications of semiochemicals, and an semiochemical that can be synthesized in the laboratory are presented. The laboratory synthesis is carried out through the…

The purpose of the study was to analyze agricultural education teachers' attitudes toward selected school components as motivational factors to continue teaching and demotivational factors to discontinue teaching. Using a mail questionnaire, the researchers employed a census study of agricultural education teachers in West Virginia (N = 90).…

Enrollment increases at many institutions have forced science faculty to reevaluate assessment decisions in light of increasing demands on time. Some have advocated the replacement of free-response examinations with forced-choice examinations as a time-saving strategy. The existing research literature contains many studies comparing student…

This paper presents a game of industrialisation, based on a paper airplane, that mimics real world production ramp-up and blends classical engineering courses together. It is based on a low cost product so that it can be mass produced. The game targets graduate students and practitioners in engineering fields. For students, it offers an experiment…

The research on the cooling law began with an article by Newton published in 1701. Later, many studies were performed by other scientists confirming or confuting Newton's law. This paper presents a description and an interpretation of Newton's article, provides a short overview of the research conducted on the topic during the 18th century, and…

Research in general chemistry laboratory instruction has rarely focused on the impact of the learning environment on the graduate teaching assistants (GTAs). We decided to investigate the effect that facilitating a well established cooperative problem-based chemistry laboratory has on GTAs' epistemological and metacognitive development, and how…

This essay presents case studies of "course-based tutoring" (CBT) and one-to-one tutorials in two sections of developmental first-year composition (FYC) at a large West Coast research university. The author's study uses a combination of rhetorical and discourse analyses and ethnographic and case study multi-methods to investigate both…

A low-cost portable fluorimeter was constructed using a 360 nm LED for excitation and a silicon photodiode for detection. The instrument is simple to operate and has been used to investigate fluorescent whitening agents extracted from various brands of paper, to determine the linear range and limit of detection of quinine in various commercial…

Cross-disciplinary (CD) learning experiences benefit student understanding of concepts and curriculum by offering opportunities to explore topics from the perspectives of alternate fields of study. This report involves a qualitative evaluation of CD health sciences undergraduate laboratory experiences in which concepts and students from two…

This study compared the educational effects of computer simulations developed in a hyper-realistic virtual environment with the educational effects of either traditional schematic simulations or a traditional optics laboratory. The virtual environment was constructed on the basis of Java applets complemented with a photorealistic visual output.…

This experiment examined the effects of alcohol on women's sexual decision making during a laboratory social interaction with a potential dating partner. Participants completed an assessment of sex-related alcohol expectancies, were randomly assigned to consume alcohol, no alcohol, or a placebo, and then interacted with a male confederate.…

Research Findings: This paper reports on children's use of science materials in preschool classrooms during their free choice time. Baseline observations showed that children and teachers rarely spend time in the designated science area. An intervention was designed to "market" the science center by introducing children to 1 science…

Human rhinovirus (HRV) is one of the most common human respiratory pathogens and is responsible for the majority of upper respiratory illnesses. Recently, a phylogeny was constructed from all known American Type Culture Collection (ATCC) HRV sequences. From this study, three HRV classifications (HRVA, HRVB, and HRVC) were determined and techniques…

Alternatives and/or supplements to animal dissection are being explored by educators of human anatomy at different academic levels. Clay modeling is one such alternative that provides a kinesthetic, three-dimensional, constructive, and sensory approach to learning human anatomy. The present study compared two laboratory techniques, clay modeling…
