A substantial number of upper-level science students and practicing physical science teachers demonstrate confusion about thermal equilibrium, heat transfer, heat capacity, and specific heat capacity. The traditional method of instruction, which involves learning the related definitions and equations, using equations to solve heat transfer…

In an attempt to address some student misconceptions in electrochemistry, this guided-inquiry laboratory was devised to give students an opportunity to use a manipulative that simulates the particulate-level activity within an electrochemical cell, in addition to using an actual electrochemical cell. Students are led through a review of expected…

We describe the organization of wet-lab special-study modules (SSMs) in the Central Research Laboratory of Dokuz Eylul Medical School, Izmir, Turkey with the aim of discussing the scientific, laboratory, and pedagogical aspects of this educational activity. A general introduction to the planning and functioning of these SSMs is given, along with…

Deaf students are attending mainstream postsecondary institutions in increasing numbers. This study attempts to fill a gap in the literature regarding deaf students' writing tutorials with hearing tutors and interpreters. It consists of observation of tutoring sessions, interviews, and collection and grounded theory analysis of relevant documents…

1898 marked a crucial point in the end of the nineteenth-century Spanish crisis. The military defeat ending the Spanish-American War was seen as proof that the country was in terminal decline. With the ideals of regeneration spreading throughout Spanish society, the State became more interested in supporting and sponsoring science and technology,…

This 8-hour experiment (spread over two 4-hour sessions) is designed to equip students with essential skills in polymer synthesis, particularly in synthesizing polymers of well-defined molecular weight. The experiment involves the synthesis and characterization of poly(vinyl neodecanoate) via living free radical polymerization, specifically the…

We have designed a new guided-inquiry laboratory for an advanced biochemistry course. This integrated laboratory focuses on the biomolecule tRNA[superscript Phe] and combines elements of bioorganic and bioinorganic chemistry with biochemistry. Throughout the semester students work together to study tRNA[superscript Phe] structure and ligand…

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…

Noncovalent interactions and physicochemical properties of amino acids are important topics in biochemistry courses. Here, we present a computational laboratory where the capacity of each of the 20 amino acids to maintain different noncovalent interactions are used to investigate the stabilizing forces in a set of proteins coming from organisms…

This paper presents an overview of how circuit models can be used for analysing wave propagation in stratified structures. Relatively complex structures can be analysed using models which are accessible to undergraduate students. Homogeneous slabs are modelled as transmission lines, and thin sheets between the slabs are modelled as lumped…

The synthesis of "N"-benzyl-2-azanorbornene via aqueous hetero Diels-Alder reaction of cyclopentadiene and benzyliminium chloride formed in situ from benzylamine hydrochloride and formaldehyde is described. Characterization of the product was achieved by IR and NMR spectroscopies. The spectral data acquired are thoroughly discussed. Numerous…

Creativity, invention, and innovation are values championed as central pillars of engineering education. However, university environments that foster open-ended design-build projects are uncommon. Fabrication and prototyping spaces at universities are typically "machine shops" where students relinquish actual fabrication activities to…

Nowadays, outreach labs are important informal learning environments in science education. After summarizing research to goals outreach labs focus on, we describe our evidence-based gene technology lab as a model of a research-driven outreach program. Evaluation-based optimizations of hands-on teaching based on cognitive load theory (additional…

Are you interested in using argument-driven inquiry for high school lab instruction but just are not sure how to do it? You are not alone. This book will provide you with both the information and instructional materials you need to start using this method right away. "Argument-Driven Inquiry in Biology" is a one-stop source of expertise,…
