Evaluating the Operational Feasibility of Using Subsets of Items to Recommend Minimal Competency Cut Scores

Establishing cut scores using the Angoff method requires panelists to evaluate every item on a test and make a probability judgment. This can be time-consuming when there are large numbers of items on the test. Previous research using resampling studies suggest that it is possible to recommend stable Angoff-based cut score estimates using a content-stratified subset of ?45 items. Recommendations from earlier work were directly applied in this study in two operational standard-setting meetings. Angoff cut scores from two panels of raters were collected at each study, wherein one panel established the cut score based on the entire test, and another comparable panel first used a proportionally stratified subset of 45 items, and subsequently used the entire test in recommending the cut scores. The cut scores recommended for the subset of items were compared to the cut scores recommended based on the entire test for the same panel, and a comparable independent panel. Results from both studies suggest that cut scores recommended using a subset of items are comparable (i.e., within one standard error) to the cut score estimates from the full test.     

The influence of match location, quality of opposition, and match status on technical performance in professional association football

The aim of this study was to examine the effects of match location, quality of opposition, and match status on the technical aspects of performance within a single professional British football team. Forty matches from the 2002--2003 and 2003--2004 domestic league seasons were notated post-event using a computerized notational analysis system with 13 on-the-ball behaviours and corresponding outcomes (successful or unsuccessful) assessed. Log-linear modelling procedures indicated that the incidences of all on-the-ball technical behaviours, with the exception of "set-pieces", were influenced by at least one of the three situation variables, with both independent and interactive effects found. In contrast, logit modelling suggested that there was no general influence of the situation variables on the outcomes of the on-the-ball behaviours. The findings emphasize the need for notational analysts and coaches to consider the potential independent and interactive effects of match location, quality of opposition, and match status when assessing the technical components of football performance, particularly those relating to behaviour occurrence. Future research should consider the effects of additional situation variables purported to influence the mental, physical, technical, and tactical components of football performance.     

Conceptualizations of nature: An interpretive study of 16 ninth graders' everyday thinking

The research reported in this article sought to provide a broader understanding of high school science students as persons by describing the personal thoughts, or everyday thinking, about a question relevant to science: What is Nature? The purpose was to gain an understanding of students' fundamental beliefs about the world on the basis that developing scientific literacy can be successful only to the extent that science finds a niche in the cognitive and cultural milieu of students. The theoretical background for this research came from cultural anthropology and the methodology was interpretive, involving student interviews. The assertions of the study in summary form were: (a) The ninth‐grade students in the study tended to discuss Nature using several different perspectives (e.g., religious, aesthetic, scientific, conservationist). A rich breadth of perspectives typically characterized any one student's discussion of Nature. (b) After 9 years of schooling, however, the level of science integration within everyday thinking remained low for many of these ninth graders. In their discussions of Nature, most volunteered little school knowledge of science. They were aware of school science topics such as the ozone layer, rain forests, and the Big Bang theory. Such topics were voluntarily mentioned but usually without elaboration even when asked. (c) Science grade success was not correlated with the concepts these ninth graders typically chose to use in a discussion about the natural world. The students with the most grade success in science had not necessarily grasped fundamental concepts about Nature and science. (d) Regardless of school grade success, including school science grade success, most of the ninth graders attached considerable importance to personal experiences with Nature. Their environmental inclinations were strong. The article ends with a discussion of the implications. © 1999 John Wiley & Sons, Inc. J Res Sci Teach 36: 541–564, 1999     

Learn before lecture: A strategy that improves learning outcomes in a large introductory biology class

Actively engaging students in lecture has been shown to increase learning gains. To create time for active learning without displacing content we used two strategies for introducing material before class in a large introductory biology course. Four to five slides from 2007/8 were removed from each of three lectures in 2009 and the information introduced in preclass worksheets or narrated PowerPoint videos. In class, time created by shifting lecture material to learn before lecture (LBL) assignments was used to engage students in application of their new knowledge. Learning was evaluated by comparing student performance in 2009 versus 2007/8 on LBL-related question pairs, matched by level and format. The percentage of students who correctly answered five of six LBL-related exam questions was significantly higher (p < 0.001) in 2009 versus 2007/8. The mean increase in performance was 21% across the six LBL-related questions compared with <3% on all non-LBL exam questions. The worksheet and video LBL formats were equally effective based on a cross-over experimental design. These results demonstrate that LBLs combined with interactive exercises can be implemented incrementally and result in significant increases in learning gains in large introductory biology classes.     

The Effects of Profanity in Violent Video Games on Players' Hostile Expectations,Aggressive Thoughts and Feelings,and Other Responses

Although effects of violence in video games have been researched extensively, no empirical studies have examined effects of profanity, a form of verbal aggression, in video games. An experiment (N = 321) investigated effects of profanity used by protagonist and antagonist characters in a “first-person shooter” game on players' hostile expectations, accessibility of aggressive thoughts, aggressive feelings, and other responses. Profanity used by both protagonist and antagonist characters increased hostile expectations, a direct precursor to aggressive behaviors. Findings suggest that profanity in video games may affect aggressive outcomes, emphasizing the need for more research investigating effects of profanity in media.     

Universal patterns or the tale of two systems? Mathematics achievement and educational expectations in post-socialist Europe

Although communist ideology claimed to destroy former class stratification based on labour market capitalist relationships, de facto during socialism one social class hierarchy was substituted for another that was equally unequal. The economic transition during the 1990s increased stratification by wealth, which affected educational inequality. This study examines the relationships among parental education, gender, educational expectations and mathematics achievement of youths in five post-socialist Eastern European countries, comparing them with three Western countries. We employed the 8th-grade data from the Trends in International Mathematics and Science Study (TIMSS) 1995 and 2007. The findings point to the universal associations between parental education and student outcomes, whereas gender comparisons present interesting East-West differences. The theoretical and policy implications of these findings are discussed.     

Contextualizing Gay‐Straight Alliances: Student,Advisor, and Structural Factors Related to Positive Youth Development Among Members

Gay‐straight alliances (GSAs) may promote resilience. Yet, what GSA components predict well‐being? Among 146 youth and advisors in 13 GSAs (58% lesbian, gay, bisexual, or questioning; 64% White; 38% received free/reduced‐cost lunch), student (demographics, victimization, attendance frequency, leadership, support, control), advisor (years served, training, control), and contextual factors (overall support or advocacy, outside support for the GSA) that predicted purpose, mastery, and self‐esteem were tested. In multilevel models, GSA support predicted all outcomes. Racial/ethnic minority youth reported greater well‐being, yet lower support. Youth in GSAs whose advisors served longer and perceived more control and were in more supportive school contexts reported healthier outcomes. GSA advocacy also predicted purpose. Ethnographic notes elucidated complex associations and variability as to how GSAs operated.
