Teaching the biological consequences of alcohol abuse through an online game: impacts among secondary students

A multimedia game was designed to serve as a dual-purpose intervention that aligned with National Science Content Standards, while also conveying knowledge about the consequences of alcohol consumption for a secondary school audience. A tertiary goal was to positively impact adolescents' attitudes toward science through career role-play experiences within the game. In a pretest/delayed posttest design, middle and high school students, both male and female, demonstrated significant gains on measures of content knowledge and attitudes toward science. The best predictors of these outcomes were the players' ratings of the game's usability and satisfaction with the game. The outcomes suggest that game interventions can successfully teach standards-based science content, target age-appropriate health messages, and impact students' attitudes toward science.     

Conceptualizing a narrative simulation to promote dialogic reflection: using a multiple outcome design to engage teacher mentors

Experienced teachers, tasked with mentoring, often find themselves inundated with large amounts of didactic information as they prepare for guiding new interns. In an effort to develop training that would both prepare new mentors and revitalize experienced mentors, a state Educational Professional Standards Board enlisted the help of instructional designers to develop an innovative online course. The focal point of the course design is a narrative simulation, embedded with standards-based information, that provides user-selected, multiple outcomes as decision points to support dialogic reflection. Theoretical and practical considerations for conceptualizing this multiple outcome strategy, quality review components and design specifications are discussed.     

The Impact of a Science/Technology/Society Teaching Approach on Student Learning in Five Domains

The purpose of the study was to examine the effectiveness of the Chautauqua Professional Development Program in terms of the mastery of basic science concepts, understanding major science processes, use of creativity skills, improvement of student attitudes toward science, and the ability to apply science concepts and processes in new situations. Participants included twelve teachers who agreed to participate in an experimental study where Science, Technology, and Society (STS) strategies were utilized with two class sections where in one class the teacher determined the course structure and the form of instruction that was typically used. Conversely, the experimental class was almost exclusively student-centered. A total of twenty-four sections of students were in STS sections (365 students) and a similar number in control sections (359 students).The data collected were analyzed using quantitative methods. The results were tabulated and contrasted for students enrolled in the two sections for all the teachers. The results indicate that students in the student-centered STS sections achieved significantly better than students in the teacher-directed STS sections in terms of understanding and use of process skills, use of creativity skills, development of more positive attitudes; and the ability to apply science concepts in new contexts. However, there were no significant differences noted with respect to mastery of basic science concepts. Apparently student-centered STS approaches result in students with conceptual understandings but it is no better than the situation where teachers guide and direct inquiry STS approaches which focus much more exclusively on specific concepts and their definitions.     

Defining the Difference: Comparing Integrated and Traditional Single-Subject Lessons

Early childhood curricula should be authentic and child-centered, however, many teachers still rely on direct instruction lessons. To better define how an integrated curriculum meets the needs of students, this study examined teacher talk and actions during instructional activities with first and second graders under two conditions: (1) subject-integrated social studies lessons of an integrated curriculum unit (experimental condition); and (2) single subject-focused mathematics lessons of a traditional separate subject curriculum (control condition). The mixed-methods study sought to define and compare characteristics of both curriculum approaches. Fourteen hours of observations were collected in each setting. In the integrated curriculum setting, the teacher was a facilitator of teamwork, offering choices, and giving praise; students made choices, decisions, and worked collaboratively. In the traditional setting, the teacher delivered direct instruction and controlled behavior; students followed directions, recalled knowledge, and worked individually. Less teacher energy was expended for behavior management in the integrated curriculum setting, indicating intrinsic motivation of students. Implementation of integrated curricula is recommended because of the student-centered focus that results in greater motivation, ownership, and teamwork, along with deeper knowledge connections. Because many factors hinder implementation, teachers need support when first teaching with this approach.     

Questioning minds on the lookout for potential workplace research and improvement markers: Practice‐based research

In the performance improvement field, performance technologists are in an ideal position to detect and investigate unexpected effects (UEs) in the workplace: those near‐invisible root variables that, once exposed, pose either potentially performance‐harming or performance‐enhancing challenges for their organization. Working with UE triggers and trends will round out performance technologists' capabilities through the adoption of what is known as practice‐based research.     

Collaboration modality, cognitive load, and science inquiry learning in virtual inquiry environments

Educational multi-user virtual environments (MUVEs) have been shown to be effective platforms for situated science inquiry curricula. While researchers find MUVEs to be supportive of collaborative scientific inquiry processes, the complex mix of multi-modal messages present in MUVEs can lead to cognitive overload, with learners unable to effectively process the rich information encountered in virtual space. In this study, we investigated the effect of communication modality on cognitive load and science inquiry learning in students completing a science inquiry curriculum in an educational MUVE. Seventy-eight undergraduate education majors from a large southwestern university participated in this control-treatment study. Significant positive results were found for reducing cognitive load for participants communicating through voice-based chat, although this reduction was not found to influence learning outcomes. We conclude that use of voice-based communication can successfully reduce cognitive load in MUVE-based inquiry curricula.     

Evaluation of a university course to promote physical activity: project GRAD

Project GRAD (Graduate Ready for Activity Daily) evaluates a university course to promote physical activity. In a randomized study, 338 university seniors participated in either an intervention or control course for academic credit, and posttest data were collected on 321. The control course was knowledge-oriented. The intervention course taught behavior change skills in weekly lectures and peer-led labs. Physical activity was assessed with 7-Day Physical Activity Recall interviews. The intervention had no significant effects on men. Among women, the intervention increased total physical activity during leisure, strengthening exercises, and flexibility exercise. This university course had the intended effects of promoting healthful patterns of physical activity among women, but no effects were observed on men, who were more active than women at baseline.     

Development of a grinding-specific performance test set-up

Abstract

The aim of this study was to develop a performance test set-up for America's Cup grinders. The test set-up had to mimic the on-boat grinding activity and be capable of collecting data for analysis and evaluation of grinding performance. This study included a literature-based analysis of grinding demands and a test protocol developed to accommodate the necessary physiological loads. This study resulted in a test protocol consisting of 10 intervals of 20 revolutions each interspersed with active resting periods of 50 s. The 20 revolutions are a combination of both forward and backward grinding and an exponentially rising resistance. A custom-made grinding ergometer was developed with computer-controlled resistance and capable of collecting data during the test. The data collected can be used to find measures of grinding performance such as peak power, time to complete and the decline in repeated grinding performance.
