Primary literature is our main mode of communication in the sciences. As such, it is important for our undergraduates in the discipline to learn how to read primary literature. Incorporating primary literature into undergraduate science courses is often difficult because students are unprepared to comprehend primary articles. Learning to read and…

Practical skills and competencies are critical to student engagement and effective learning in laboratory courses. This article describes the design of a yearlong, stand-alone laboratory course--the Biotechniques Laboratory--a common core course in the second year of all our degree programs in the biological sciences. It is an enabling,…

Two experiments using the science topics of Magnetism and Light were conducted with younger learners (Year 5) who had no prior knowledge of the topics, and older learners (Year 6) who had studied the topics previously. Half of the learners were presented the information in auditory form only while the other half were presented the auditory…

The speed of sound is a physical property that can be measured easily in the lab. However, finding an inexpensive and intuitive way for students to determine this speed has been more involved. The introduction of affordable consumer-grade high-speed cameras (such as the Exilim EX-FC100) makes conceptually simple experiments feasible. Since the…

The purpose of this study was to establish what impact experimental work has on the understanding of scientific concepts, what pupils remember about the experiments they carried out and how they are able to formulate and understand the experiment plan. A sample of 386 pupils aged 13+ participated in the research, of which 162 in the experimental…

Drawing from theory and research on perceived stigma (Pryor, Reeder, Yeadon, & Hesson-McInnis, 2004), attentional processes (Rinck & Becker, 2006), working memory (Baddeley & Hitch, 1974), and regulatory resources (Muraven & Baumeister, 2000), the authors examined discrimination against facially stigmatized applicants and the processes involved.…

This study examined the impact of collaborative filtering (the so-called recommender) on college students' use of an online forum for English learning. The forum was created with an open-source software, Drupal, and its extended recommender module. This study was guided by three main questions: 1) Is there any difference in online behaviors…

The construction of the European Higher Education Area has been an adaptation challenge for Spanish universities. New methodologies require a more active role on the students' part and come into conflict with the previous educational model characterised by a high student/professor ratio, a lecture-based teaching methodology and a summative…

A lithography lab course has been developed that is applicable to students from the middle-school level up to college students. It can also be inserted into electronics technology or similar courses in two- and four-year colleges, or used to demonstrate applications of polymers in chemistry classes. Some of these techniques would enable research…

We present a novel first-year chemistry laboratory experiment that connects solubility, equilibrium, and chemical periodicity concepts. It employs a unique format that asks students to replicate experiments described in different sample lab reports, each lacking some essential information, rather than follow a scripted procedure. This structure is…

We describe an experiment for the undergraduate organic laboratory curriculum in which 2-bromoacetophenone is converted to 2-fluoroacetophenone using a solid-phase nucleophilic fluorine source. The experiment introduces students to the utility of solid-phase reagents in organic synthesis, to NMR-active nuclei other than [to the first power]H…

A microscale experiment is presented in which cyclohexene is dihydroxylated under three sets of conditions: epoxidation-hydrolysis, permanganate oxidation, and the Woodward dihydroxylation. The products of the reactions are determined by the use of thin-layer chromatography. Teams of students are presented with proposed mechanisms for each…

In this article a potentiometric method for reducing sugar quantification is described. Copper(II) ion reacts with the reducing sugar (glucose, fructose, and others), and the excess is quantified using a copper wire indicator electrode. In order to accelerate the kinetics of the reaction, working conditions such as pH and temperature must be…

An undergraduate biochemistry laboratory experiment that will teach the technique of fluorescence resonance energy transfer (FRET) while analyzing protein-induced DNA bending is described. The experiment uses the protein TATA binding protein (TBP), which is a general transcription factor that recognizes and binds specific DNA sequences known as…

For curriculum content-related reasons, inquiry activities can be difficult in classrooms unless the activities are approached in a manner that makes variations among student group findings understandable in the context of the study. Studies of individual animals and plant reactions to stimuli, such as insect exploratory behavior, allow the…
