This study investigated the impact of alcohol mixed with artificially sweetened or carbohydrate containing beverages on breath alcohol concentration s (BrAC) under various levels of hydration status. Two groups of males participated in 3 experimental trials where alcohol was consumed under three different levels of hydration status. One group…

We describe a range of practical activities that allows students to investigate the properties and applications of magnets. The activities can be used in isolation or used together to build a rounded understanding of the subject area. The activities include simple demonstrations using common or inexpensive equipment, hands-on experiments for small…

We describe an activity-based approach for teaching aqueous solubility to introductory chemistry students that provides a more balanced presentation of the roles of energy and entropy in dissolution than is found in most general chemistry textbooks. In the first few activities, students observe that polar substances dissolve in water, whereas…

Experimental Psychology is a required course for psychology majors at Texas A&M University--Texarkana. This course is designed to familiarize students with the typical methods and techniques employed in psychological research. I believe that to fully understand research one must experience it, so I incorporated an in-class experiment designed…

One of the innovations in the Slovenian school system has been the introduction of elective subjects in the curricula of primary and secondary schools, thus there is a lack of teaching manuals for practical exercises and hands-on classroom experience. This situation is reflected in the Ethology classroom and for that purpose we prepared…

In this article, we examine the relationship between how students are positioned in social encounters and how this influences learning in a technology-supported science project. We pursue this topic by focusing on the participation trajectory of one particular learner. The analysis shows that the student cannot be interpreted as one type of…

This article will illustrate how a problem-based learning (PBL) course (Savery, 2006) can be used in a writing program as a vehicle for both creative and preprofessional learning. English 420: Writing, Publishing, and Editing is offered every fall, and its counterpart, English 423: Writing, Publishing, and Editing is offered each spring. The…

In e-learning systems, tutors have a significant impact on learners' life to increase their knowledge level and to make the learning process more effective. They are characterized by different features. Therefore, identifying tutoring styles is a critical step in understanding the preference of tutors on how to organize and help the learners. In…

Does correctly answering a test question about a multiterm fact enhance memory for the entire fact? We explored that issue in 4 experiments. Subjects first studied Advanced Placement History or Biology facts. Half of those facts were then restudied, whereas the remainder were tested using "5 W" (i.e., "who, what, when, where",…

Reward has been shown to change behavior as a result of incentive learning (by motivating the individual to increase their effort) and instrumental learning (by increasing the frequency of a particular behavior). However, Palminteri et al. (2011) demonstrated that reward can also improve the incidental learning of a motor skill even when…

It is currently unknown how many Institutional Review Boards (IRBs) exist at community colleges. This study investigates the percentage of public and Tribal community colleges that have active IRBs. It also examines the potential relationships between states that allow community colleges to confer baccalaureate degrees, or that have articulation…

The difficulty in covering chemical engineering concepts using traditional lectures and whiteboard teaching approaches means today's students' learning demands are unfulfilled, so alternate methods are needed. Desktop learning modules (DLMs) are designed to show industrial fluid flow and heat transfer concepts in a standard classroom so students…

The article is devoted to the currently pressing high-education problem of formation of readiness by future teachers for their professional and pedagogic cooperation work. It describes the research on development, implementation, and results of methods of forming future teachers' readiness of different levels. Based on the approach to readiness as…

An "explanatory drive" motivates children to explain ambiguity. Individuals with autism spectrum disorders are interested in how systems work, but it is unknown whether they have an explanatory drive. We presented children with and without autism spectrum disorder unsolvable problems in a physical and in a social context and evaluated…

The mainstream agricultural literacy movement has been mostly focused on school-based learning through formal curricula and standardized non-formal models (e.g., FFA, 4-H). The purpose of the current study is to qualitatively explore through a grounded theory approach, the development, sharing, and translation of diverse forms of agricultural…
