Interest in using classroom experiments to teach economics is increasing whereas empirical evidence on how experiments affect learning is limited and mixed. The author used a pretest-posttest control-group design to test whether classroom experiments and grade incentives that reward performance in experiments affect learning of introductory…

The reporting, analysis, and management of adverse events (AEs) provide an ongoing assessment of risk in the context of a clinical trial and enhance the protection of human research participants and the informed consent process. Effective and efficient review of AEs has been a long-standing challenge for Institutional Review Boards (IRBs) and…

In this article, the authors discuss the technologies of normalization and self in relation to ethics and the problematization of extrinsic research ethics. They argue that institutional review boards (IRBs) and other similar institutional mechanisms promote extrinsic forms of ethics that are exemplified through institutionalized structures such…

Recent demonstrations of "reconsolidation" suggest that memories can be modified when they are reactivated. Reconsolidation has been observed in human procedural memory and in implicit memory in infants. This study asks whether episodic memory undergoes reconsolidation. College students learned a list of objects on Day 1. On Day 2, they received a…

In the so-called electric Aharonov-Bohm effect, a quantum interference pattern shift is produced when electrons move in an electric field free region but, at the same time, in the presence of a time-dependent electric potential. Analogous fringe shifts are observed in interference experiments where electrons, travelling through an electrostatic…

The article is a historical recollection of how, for a short while, the Muslim community came to be involved in a teacher training programme and reflects on the underlying issues that had to be addressed. It also considers the impact on the host institution and implications for Muslim students, together with the lessons that should have been…

Some simple modeling with Riemann sums can be used to develop Beer's Law, which describes the relationship between the absorbance of light and the concentration of the solution which the light is penetrating. A further application of the usefulness of Beer's Law in creating calibration curves is also presented. (Contains 3 figures.)

From the streets of clouds to the submarine sand ripples or the striations on the coats of some animals, nature offers many examples of spontaneous patterned structures originating from various instabilities. These patterns can in turn destabilize and show a rich, complex dynamics and possibly end up in disordered behaviours. For over 20 years,…

To enhance bioengineering in the chemical engineering curriculum, a Unit Operations experiment simulating the hemodialysis of creatinine was implemented. The blood toxin creatinine was used for developing a more realistic dialysis experiment. A dialysis model is presented that allows students to assess the validity of model assumptions. This work…

The ice cream laboratory experiment is designed to illustrate and promote discussion of several engineering and science topics including material and energy balances, heat transfer, freezing, mass transfer, mixing, viscosity, and freezing point depression in a sophomore level engineering class. A pre-lab assignment requires the students to develop…

This study examines how feedback interest after career assessment can be influenced by changing individuals' beliefs about the importance and modifiability of the various performance dimensions. In an experiment, 82 master students completed a computerized assessment tool developed for assessing managerial potential. Results showed that…

Advanced Placement (AP) Chemistry and the National AP Chemistry Examination are both critical to secondary level institutions nationwide. The use of a national embossing stamp to attest to successful completion of an AP Chemistry course and exam to ensure college credit is a novel idea worth consideration. Moreover, the concept could be expanded…

Experiential learning is the process of creating knowledge through the transformation of experience and has been adopted in an increasing number of areas. This paper investigates the possibility of technological support for experiential learning. A learning activity flow (or script) and a mobile technology system were designed to facilitate…

Using meta-analysis, randomized experiments in education that either clearly did or clearly did not experience student attrition were examined for the baseline comparability of groups. Results from 35 studies suggested that after attrition, the observed measures of baseline comparability of groups did not differ more than would be expected given…

Human adults generally find fast tempos more arousing than slow tempos, with tempo frequently manipulated in music to alter tension and emotion. We used a previously published method [McDermott, J., & Hauser, M. (2004). Are consonant intervals music to their ears? Spontaneous acoustic preferences in a nonhuman primate. Cognition, 94(2), B11-B21]…
