Reconceptualizing TPACK to Meet the Needs of Twenty-First-Century Education

As technology continues developing and being integrated into all facets of society, it has a direct impact on education. In response, TPACK (Mishra & Koehler, 2006) was developed as a framework to guide how teachers think about the relationship between their knowledge of pedagogy, content, and technology. However, since its first articulation, significant changes to the technology have occurred. Plus, upon careful review, TPACK’s basis in research, selection of terms, and focus on teacher knowledge limited its usefulness. In response, research that supports TPACK’s multiple dimensions was added, which resulted in TPACK being focused on students learning twenty-first-century skills.     

Mapping the landscapes of bullying

Past bullying research has consistently identified common locations (e.g. bathrooms, hallways, playgrounds) on school campuses where bullying occurs, but not specific locations. This limitation does not allow researchers to take into account the unique geography of individual schools and how it contributes to bullying. A random sample of 741 grade 4–6 students from nine different elementary schools identified where bullying occurs on a campus map and this information was analysed in Geographic Information Systems (GIS). While this study offers preliminary findings (e.g. diffusion of bullying, specific locations for bullying) that increase awareness about bullying, the emphasis in this paper is to present a new methodological tool in the analysis of bullying. The use of GIS mapping to analyse bullying offer researchers an advanced instrument to understand the experience of bullying within the physical context of a school. These preliminary findings focus future research.     

The Influence of Social Norms on College Student Alcohol and Marijuana Use

The Alcohol and Other Drug survey (adapted from D. Thombs, 1999) was administered to 235 undergraduates at a southeastern university to assess the influence that gender‐specific normative perceptions have on 2 substance abuse patterns. Multiple regression analyses confirmed that gender‐specific normative beliefs accounted for variance in alcohol use intensity and frequency of marijuana use beyond the variance accounted for by sociodemographic variables. Implications for college counselors are discussed.     

Taste quality and extinction of a conditioned taste aversion in rats

Rats (Rattus norvegicus) that received a taste cue (saccharin, saline, quinine, or sucrose) paired with a lithium chloride (LiCl) injection displayed a robust decrease in consumption of that taste, relative to controls that had the taste unpaired with LiCl. Consumption of the paired taste increased with each nonreinforced presentation (i.e., extinction). After asymptotic extinction, rats that had had a 0.1% saccharin cue paired with LiCl consumed less of the saccharin solution than did controls. A similar data pattern was observed with a 10% sucrose solution. These results are consistent with the view that some aspect of the excitatory CS-US association remains after extinction. On the other hand, rats that had a bitter (0.005% or 0.001% quinine) or salty (1% or 0.5% saline) solution paired with LiCl drank similar amounts of the fluid as controls after asymptotic extinction treatment. Together, these experiments suggest that a taste that is either sweet or preferred is required in order to demonstrate the chronic decrease in fluid consumption after extinction treatment. The data suggest that the conditioning experience prevents the later development of a preference for the sweet taste, rather than there being a retained aversion that suppresses fluid consumption.     

Supporting complex problems: an examination of Churchman's inquirers as a knowledge management foundation

This paper examines the current knowledge management (KM) research through the lens of Churchman's inquiring systems. These inquiring systems are ideal foundations from which to view KM and its associated research because knowledge creation and organizational learning are critical elements of KM. Churchman proposed that organizations should support knowledge creation and learning through emphasis on problem structure and appropriate inquiring strategies. This paper discusses the characteristics of Churchman's inquirers, the problem structure for which they are most appropriate, and presents examples of each. Then, examples of previous research that share characteristics of the most complex inquirers are discussed. Organizational benefits from the inquiring system approach and guidelines for future research are suggested.     

Preliminary development of a questionnaire to assess peer athlete mentoring functions: the Athlete Mentoring Questionnaire (AMQ)

Using a multiphase approach, the purpose of the present study was to develop a psychometrically sound questionnaire to measure protégés’ perceptions of peer athlete mentoring functions. Phase 1 consisted of three stages: (a) item development, (b) assessment of content validity via think-aloud interviews with peer mentored athletes, and (c) assessment of content validity via an expert rating panel. In phase 2, 377 Canadian National team and varsity athletes who were peer mentored completed an initial 42-item version of the Athlete Mentoring Questionnaire (AMQ) and its factor structure was examined using confirmatory factor analysis (CFA), exploratory structural equation modeling (ESEM), and hierarchical ESEM (ESEM-within-CFA). Measurement invariance testing was also performed in phase 2. The final version of the AMQ contains 34 items that measure six peer athlete mentoring functions. It is hoped that the development of the AMQ will spur research in the emerging area of peer athlete mentoring.     

Partial swing golf shots: scaled from full swing or independent technique?

Abstract

During practice and competition, golfers are required to use submaximal effort to hit the ball a given distance, i.e., perform a partial shot. While the full golf swing has undergone extensive research, little has addressed partial shots and the biomechanical modifications golfers employ. This study investigates the biomechanical changes between full and partial swings, and determines if the partial swing is a scaled version of the full swing. Using a repeated measures design, 13 male golfers completed a minimum of 10 swings in the full and partial swing conditions, whilst club, ball, kinematic, and kinetic parameters were recorded. Large and statistically significant reductions in body motion (centre of pressure ellipse: 33.0%, p = 0.004, d = 2.26), combined with moderate reductions in lateral shift (25.5%, p = 0.004, d = 0.33) and smaller reductions in trunk rotation (arm to vertical at top of backswing: 14.1%, p = 0.002, d = 2.58) indicate golfers favour larger reductions in proximal measures, combined with diminished reductions as variables moved distally. Furthermore, the partial swing was not found to be a scaled version of the full swing implying a new approach to coaching practices might be considered.
