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…

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,…

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…

This paper focuses on connecting natural sciences education with Cultural Historical Activity Theory (CHAT). In this sense, natural sciences education is considered as a lifelong learning procedure, not seen as an individual but as a collective activity. Moreover, learning becomes a human activity in which theory and praxis are strongly connected…

This research aims to explore the problems that teacher have experienced their opinion towards effectives and and functionality of teaching-learning process of Primary Science and Technology curriculum started to be implemented in 2004-2005 academic year in Turkey. The qualitative research design is used in this study. Research data are collected…

The introduction of outcomes-based education in South Africa placed many challenges on the transformation of science classrooms. The 2009 National Education Evaluation and Development Unit (NEEDU) Report concluded that South African rural and township schools are largely dysfunctional. This article examined some of the reasons for the…
