Outcome-based education (OBE) is a current initiative in Hong Kong universities, with widespread backing by governments and standards bodies. However, study of students’ perceptions of OBE and validation of understanding these perceptions are lacking. This paper reports on the validation of an OBE-specific instrument and resulting preliminary findings. Instrument responses (= 89) were analysed using Rasch and exploratory/confirmatory factor analyses. Both approaches identified two dimensions (i.e. evaluation and comparison). Challenges and modifications to the instrument items and their relationships to constructs are discussed. Preliminary findings suggest students did not perceive significant differences between OBE and traditionally organised courses. Lack of explicit discussion of OBE with the students may have denied students the ability to make fully informed evaluations of OBE innovations. Implications for instrument validation and evaluation of initiatives in an OBE context are discussed as is the broader issue of transparency in teacher education curriculum design and implementation.  相似文献

The purpose of this article is to inform readers about the types of instruments available for assessing and improving mentoring in organizations. Extensive review of the psychological, business and medical literature was conducted to identify commercially published, practitioner‐oriented instruments. All of the instruments that were identified – including the Alleman mentoring activities questionnaire, Mentoring in the moment, Mentoring skills assessment, and Principles of adult mentoring scale – are evaluated herein. Each instrument’s target audience, raters, subscales, response options, psychometric properties, and relative strengths and weaknesses are described. Although these instruments are reported to be used extensively, evidence of their validity is not always available. This review presents information that, in combination with first‐hand inspection of the instruments, should enable practitioners to differentiate between instruments that may be a fit for their needs from those that are not. Furthermore, it may introduce academic readers to instruments that are not covered in the scholarly literature in spite of their common use for non‐research purposes.  相似文献

The purpose of this study was to examine the factorial validity and reliability of the Achieving the NASPE Standards Inventory (ANSI) that assesses pre-service physical education teachers' perceptions of achieving the National Association for Sport and Physical Education (NASPE) beginning teacher standards (2003). Four hundred fifty-two pre-service teachers from 15 Physical Education Teacher Education (PETE) programs voluntarily and anonymously completed the inventory. The hypothesized measurement models were analyzed by means of a confirmatory factor analysis. The Goodness-of-fit statistics indicated that the modified 3-factor model with 38 items represented a best fitting model with the data. The scores generated by the total and the 3 subscales of the 38-item ANSI demonstrated a high level of internal consistency.  相似文献

Abstract

In recent years, volunteering has received strong research attention from both scholars and practitioners. For the most part, involvement in volunteer activities has been identified as an important determinant of future volunteering. Through revalidating an existing instrument, the purpose of this study was to assess the dimensions of volunteer satisfaction at the 2012 London Olympic Games and its impact on future volunteer behaviour. The findings of this study shed light on the identification of volunteer satisfaction factors in the mega sporting event setting, particularly for a unique type of volunteer (i.e. media worker) assigned to a special set of tasks. Unlike Galindo-Kuhn and Guzley’s results that revealed participation efficacy and group integration to be strong predictors of volunteer satisfaction, organizational support was the primary predictor for media centre volunteers’ re-participation intention towards future volunteering programmes.  相似文献
