Instructional television and student attitudes toward teacher,course, and medium

Summary and conclusions Semantic Differential data were obtained from 234 ninth graders who had just completed an algebra course which included a televised lecture presenting a new approach to the subject matter, and from 269 pupils who had had algebra taught in the usual way.     

Impact evaluation of quality assurance in higher education: methodology and causal designs

In this paper, the theoretical perspectives and general methodological elements of impact evaluation of quality assurance in higher education institutions are discussed, which should be a cornerstone of quality development in higher education and contribute to improving the knowledge about the effectiveness (or ineffectiveness) of quality assurance. The suggested core methodology consists in comparative and longitudinal studies carried out simultaneously to the quality assurance interventions and relying on surveys and mixed methods. The methodology is applicable to any particular quality assurance procedure and any achievement area of higher education institutions. To round off the methodology presentation, an overview of causal designs, in particular causal social mechanisms, for impact analyses of quality assurance in higher education institutions and its challenges and limits is outlined and some characteristics of survey questionnaire construction are given.     

The Python Project: A Unique Model for Extending Research Opportunities to Undergraduate Students

Undergraduate science education curricula are traditionally composed of didactic instruction with a small number of laboratory courses that provide introductory training in research techniques. Research on learning methodologies suggests this model is relatively ineffective, whereas participation in independent research projects promotes enhanced knowledge acquisition and improves retention of students in science. However, availability of faculty mentors and limited departmental budgets prevent the majority of students from participating in research. A need therefore exists for this important component in undergraduate education in both small and large university settings. A course was designed to provide students with the opportunity to engage in a research project in a classroom setting. Importantly, the course collaborates with a sponsor''s laboratory, producing a symbiotic relationship between the classroom and the laboratory and an evolving course curriculum. Students conduct a novel gene expression study, with their collective data being relevant to the ongoing research project in the sponsor''s lab. The success of this course was assessed based on the quality of the data produced by the students, student perception data, student learning gains, and on whether the course promoted interest in and preparation for careers in science. In this paper, we describe the strategies and outcomes of this course, which represents a model for efficiently providing research opportunities to undergraduates.     

Self-presentation origins of choking: evidence from separate pressure manipulations

Whether self-presentation is involved in the choking process remains unknown. The purpose of the current study was to determine the role of self-presentation concerns on the frequency of choking within the context of a recently proposed self-presentation model. Experienced field hockey players (N = 45) were randomly assigned to one of five groups (i.e., performance-contingent monetary incentive, video camera placebo, video camera self-presentation, audience, or combined pressure), before taking penalty strokes in low- and high-pressure phases. Results indicated that groups exposed to self-presentation manipulations experienced choking, whereas those receiving motivational pressure treatments decreased anxiety and increased performance under pressure. Furthermore, cognitive state anxiety mediated the relationship between the self-presentation group and performance. These findings provide quantitative support for the proposed self-presentation model of choking, while also holding implications for anxiety manipulations in future sport psychology research.
