This work applies a cultural historical activity theory (CHAT) framework to understand how the outcome of a high school laboratory task may be positively influenced without making changes to the hands-on practical task itself. Informed by cognitivism, novel practical instruction videos that were based on the same video but had different audio…

This study investigated the effect of different assessment types on overall success in an online geoscience course covering energy's impact on the environment. Two groups took either the slower 1-credit or the faster 3-credit version of the course, which utilized the same content. Self-assessment questions developed using H5P, quizzes, summative…

Seeking to support graduate student writers, writing centers at research universities have developed highly successful dissertation camps over the past 15 years. Previous research from North American dissertation camps has demonstrated significant benefits from these camps, as dissertation writers developed new writing habits and increased their…

A teaching team composed of a faculty member (lecture) and a graduate teaching assistant (lab) endeavored to engage students enrolled in several sections of the same organic chemistry course through the use of social media. Students were encouraged to follow both instructors on Twitter and were asked to share aspects of the class using the social…

This case study demonstrates teaching and learning activities in the school laboratory, and employs talk moves for the direct assessment of practical task effectiveness. By adopting a sociocultural linguistic approach (SCLA), learning chemistry is understood to be a discursive process in which knowledge is constructed through social interaction…

A detailed characteristic of teaching and learning approaches used within the new concept of Learning by Being (LBB) is given. The evolution of educational paradigms from Learning by Doing (LBD) and Learning by Understanding (LBU) toward LBB is analyzed. The basic idea of LBB is students' ownership on cognitive goals, or the assumption of learning…

The purpose of this three-article dissertation was to expand knowledge and theory regarding digital tool use in biology laboratory courses, such as microbiology, which requires specific laboratory skill development through the perception of instructors and students. Article 1 establishes the broad digital literacy and fluency problem in education…

A synthesis of the "R,R"-tartrate salt of the popular anti-Parkinson's drug "R"-rasagiline (Azilect) was adapted to introduce the organic laboratory student to a medically relevant synthesis. It makes use of concepts found in the undergraduate organic chemistry curriculum, appropriately fits into three approximately 4 h lab…

A Wolff-Kishner reaction that does not require hydrazine has been developed. The reaction sequence has two steps: formation of a carbomethoxyhydrazone from methyl hydrazinocarboxylate and acetophenone, then decomposition of this intermediate by treatment with potassium hydroxide in triethylene glycol. Purification is by filtration through a plug…

Ocean acidification refers to the process by which seawater absorbs carbon dioxide from the atmosphere, producing aqueous carbonic acid. Acidic conditions increase the solubility of calcium carbonate, threatening corals and other calcareous organisms that depend on it for protective structures. The global nature of ocean acidification and the…

Heteronuclear multidimensional NMR techniques are commonly used to study protein structure, function, and dynamics, yet they are rarely taught at the undergraduate level. Here, we describe a senior undergraduate laboratory where students collect, process, and analyze heteronuclear multidimensional NMR experiments using an unstudied Ig domain (Ig2…

Introductory organic laboratory courses frequently begin with a set of activities built around developing basic experimental skills and techniques, often with guided-inquiry components. A sequence of skill-based activities is described to promote reflection, analysis of, and interpersonal communication around science. A multistage process was used…

FRET (Fo¨rster resonance energy transfer) involves the transfer of energy from an excited donor fluorophore to an acceptor molecule in a manner that is dependent on the distance between the two. A biochemistry laboratory experiment is described that teaches students how to use FRET to evaluate distance changes in biological molecules. Students…

A green organic-inorganic laboratory experiment has been developed in which students prepare a self-assembling iron cage in D[subscript 2]O at room temperature. The tetrahedral cage captures a small, neutral molecule such as cyclohexane or tetrahydrofuran. [Superscript 1]H NMR analysis distinguishes captured and free guests through diagnostic…

A laboratory exercise was devised that allows students to rapidly and fairly accurately determine the iodine value of oleic acid. This method utilizes the addition of elemental bromine to the unsaturated bonds in oleic acid, due to bromine's relatively fast reaction rate compared to that of the traditional Wijs solution method. This method also…
