Instead of solving ordinary differential equations (ODEs), the damped simple harmonic motion (SHM) is surveyed qualitatively from basic mechanics and quantitatively by the instrumentality of a graph of velocity against displacement. In this way, the condition b ? [square root]4mk for the occurrence of the non-oscillating critical damping and…

Although the literature on institutional diversity suggests that quality assurance practices could affect institutional diversity, there has been little empirical research on this relationship. This article seeks to shed some light on the possible connection between quality assurance practices and institutional diversity by examining the…

In this laboratory experiment, upper-division undergraduate chemistry and biochemistry majors investigate amide-bond-forming reactions from a green chemistry perspective. Using hydrocinnamic acid and benzylamine as reactants, students perform three types of amide-forming reactions: an acid chloride derivative route; a coupling reagent promoted…

In this classroom experiment, students see how low bank equity requirements can interact with deposit insurance to encourage excessive risk-taking. The experiment fills a niche Admati and Hellwig (2013) have noted: citizens in a democracy must understand why bank owners argue for low equity requirements and why society as a whole is better off…

Two experiments investigated whether 4- and 5-year-old children choose to learn from informants who use more complex syntax (passive voice) over informants using more simple syntax (active voice). In Experiment 1 (N = 30), children viewed one informant who consistently used the passive voice and another who used active voice. When learning novel…

The validation model of causal bridging inferences proposed by Singer and colleagues (e.g., Singer in "Can J Exp Psychol," 47(2):340-359, 1993) claims that before a causal bridging inference is accepted, it must be validated by existing knowledge. For example, to understand "Dorothy took the aspirins. Her pain went away," one…

In this article, we describe a basic practical laboratory designed for fifth-year undergraduate students of Microbiology as part of the Epidemiology course. This practice provides the students with the tools for molecular epidemiological analysis of pathogenic microorganisms using a rapid and simple PCR technique. The aim of this work was to assay…

Analyzing protein structure has become an integral aspect of understanding systems of biochemical import. The laboratory experiment endeavors to introduce protein folding to ascertain structures of proteins for which the structure is unavailable, as well as to critically evaluate the quality of the prediction obtained. The model system used is the…

This paper is linked to a study aiming to provide a theoretical rationale for the methodological foundations of the use of interactive learning technology in institutions of higher learning and undertakes to describe the process of practical implementation of this approach and analyze the outcomes. The authors examine the views expressed by…

Educational research has found that students have challenges understanding thermal science. Undergraduate physics students have difficulties differentiating basic thermal concepts, such as heat, temperature, and internal energy. Engineering students have been found to have difficulties grasping surface emissivity as a thermal material property.…

The paper focuses on student-teachers' geometric diagrams to mediate the emergence of different proofs for a geometric proposition. For Peirce, a diagram is an icon that explicitly and implicitly represents the deep structural relations among the parts of the object that it stands for. Geometric diagrams can be seen as epistemological tools to…

In this paper, we present a dataset consisting of data generated from 22 previously and currently running randomized controlled experiments inside the ASSISTments online learning platform. This dataset provides data mining opportunities for researchers to analyze ASSISTments data in a convenient format across multiple experiments at the same time.…

Research on learning in the undergraduate chemistry laboratory necessitates an understanding of students' perspectives of learning. Novak's Theory of Meaningful Learning states that the cognitive (thinking), affective (feeling), and psychomotor (doing) domains must be integrated for meaningful learning to occur. The psychomotor domain is the…

We describe the content and organization of a series of day-long field trips to a university for high school students that connect chemistry content to issues of sustainability. The seven laboratory activities are in the areas of environmental degradation, energy production, and green chemistry. The laboratory procedures have been modified from…

Pre-recorded video demonstrations of laboratory experiments are used to introduce students to various experiments in a lab course instead of an in-class tutorial. In addition to saving time for both the students and the instructor, this allows students to watch the videos in an "on-demand" setting at their convenience, which is helpful…
