Describes an organic chemistry experiment for teaching the basic concepts of chemical kinetics. Provides background information about first- and second-order reactions, experimental procedures of the Diels-Alder reaction between cyclopentadiene and dimethyl fumarate, and the experimental results. (YP)

Describes experimental procedures to produce magnetic fields with a thermocouple. Provides diagrams showing the apparatus, tables of experiment data, and background information on the theory. (YP)

Describes ways to make use of lab activities and time for effective learning and student motivation. Provides information on the classification of lab activities, class data for measuring student power output, and a sample pre-lab "think sheet" activity. States the importance of relating activities to topics studied. (RT)

Provided are two experiments which deal with the formation of callus and embryos from tissue culture of carrot roots. Outlined are the purpose, materials, procedure, and results for each. (RT)

Introduces an experiment involving the observation of Brownian motion for college students. Describes the apparatus, experimental procedures, data analysis and results, and error analysis. Lists experimental techniques used in the experiment. Provides a circuit diagram, typical data, and graphs. (YP)

Reported are observational limits of detectability for several single stimulus and multi-stimuli observation tasks in secondary level chemistry. Provided are tables of actual results obtained including type of observation, chemical system used, method of determining stimulus magnitude, and observational thresholds. (Author/YP)

Describes a classroom experiment in which students see how competitive markets underproduce in the presence of a positive externality. States that this experiment is used in a principles of economics course to introduce the idea of market failure. Explains that participants take the role of buyers of education, sellers of education, or interested…

Although reports of academic cheating are abundant, there are relatively few papers in the literature that focus on cheating in the context of science courses and even fewer that address dishonest practices, such as "cooking" or fudging data, within the classroom laboratory. This paper briefly reviews the existing literature on academic dishonesty…

Practical classes on protein expression and purification were given to undergraduate biology students enrolled in the elective course "Introduction to Genetic Engineering." The heterologous expression of the green fluorescent protein (GFP)* of "Aequorea victoria" is an interesting system for didactic purposes because it can be viewed easily during…

Analogous thinking has been commonly discussed as being an inherent and distinguishing characteristic of human cognition (e.g., Gentner, 2010; Goldstone, Day, & Son, 2010; Holyoak, in press; Rittle-Johnson & Star, in press). Gentner (2003) has argued that as part of the human cognitive toolbox, comparison accompanied by the relational language to…

Health and education are two important issues in developing economies. Field and natural experiments provided me with great opportunities for identifying the effects of health insurance and incentive on doctors' prescribing behaviors and the peer influences among students. The first chapter examines whether doctors write more expensive…

This paper proposes extensive applications of virtual collaborative space in order to enhance the efficiency and capability of Digital Campus. The usability of Digital Campus has been experimented in different learning environments and evaluated by questionnaire as that the presence technology and a sense of solidarity influence the participants'…

Purpose: The purpose of this paper is to investigate the usability (effectiveness, efficiency and user satisfaction) of e-feedback interfaces. The experiment compares a traditional visual approach with a multimodal approach in order to determine the impact of multimodal metaphors upon the user's understanding, reasoning and engagement with the…

This study looks at the relationship between age, technology experience, and design factors in determining young children's comprehension of novel digital interfaces. In Experiment 1, 35 preschoolers played three games that varied in complexity and familiarity. Parental questionnaires were used to assess children's previous technology experience.…
