How competent do teachers feel instructing self-regulated learning strategies? Development and validation of the teacher self-efficacy scale to implement self-regulated learning     

《Teaching and Teacher Education》2018

This study describes the development of a self-report instrument: the Teacher Self-Efficacy Scale to implement Self-Regulated Learning (TSES-SRL). The TSES-SRL assesses teachers' perceived ability of implementing SRL as a specific instructional domain. The process of the item and scale development is presented. Exploratory factor analysis suggests a four-factor structure. Next, confirmatory factor analysis was performed and goodness of fit estimates were calculated, indicating an acceptable fit. Further, comparing the TSES-SRL to The Ohio State Teacher Efficacy Scale reveals the domain-specificity of the instrument. Overall, the TSES-SRL is considered a useful instrument to measure teachers' feelings of competence regarding SRL implementation.  相似文献   

Validating a shortened form of the ARC for special populations     

Mark Bond  Carrie-Lou Garberoglio  Sarah Schoffstall  Jackie Caemmerer  Stephanie Cawthon 《Educational Assessment》2018,23(1):69-84

Autonomy describes cognition or behavior that is self-directed, according to personal interests, and free from external influence. This construct is of importance to students who are deaf because it has been shown to be positively related to their post-school transition outcomes, and this population faces unique challenges in this area. To conduct research with this construct, it is necessary to use measures that are valid and reliable for the population of interest. Therefore, a set of exploratory and confirmatory factor analyses validated the unidimensionality of a shortened form of the ARC Self-Determination Scale’s autonomy dimension. A three-factor solution, including a social skills dimension, was measurement-invariant across many groups of students, including those with learning disabilities, emotional disturbances, speech and language impairments, and other health impairments. Although the shortened form of this scale was not unidimensional, as hypothesized, the generalizability of its measurement properties may prove useful. Discussion highlights the differences between these three dimensions and Wehmeyer's theory of self-determination.  相似文献   

“持有至到期投资”的确认与计量方法商榷     

毛波军 《孝感职业技术学院学报》2009,12(2):63-65,100

《2006企业会计准则第22号——硷融工具确认和计量》中规定“持有至到期投资”科目,应当采用实际利率法,按摊余成本计量。笔者认为这种会计核算方法设计过于繁琐,“持有至到期投资”采用直线法进行会计核算明显优于实际利率法,有利于会计核算工作。  相似文献

Muscle Soreness Following Resistance Exercise With and Without Eccentric Contractions     

William C. Byrnes  Priscilla M. Clarkson  Frank I. Katch 《Research quarterly for exercise and sport》2013,84(3):283-285

The present study reported on translating the Exercise Identity Scale (EIS: Anderson &; Cychosz, 1994) into Greek and examining its psychometric properties and cross-cultural validity based on U.S. individuals' EIS responses. Using four samples comprising 33, 103, and 647 Greek individuals, including exercisers and nonexercisers, and a similar sample comprising 800 U.S. individuals, the concurrent validity, factor structure, internal reliability, test-retest reliability, external validity, gender invariance, and cross-cultural validity of the EIS responses were examined using confirmatory factor analytical procedures. The results supported the concurrent validity, an adequate unidimensional factor structure for the translated EIS and the internal reliability and test-retest reliability over a 6-week interval. Further, cross-gender configural, partial metric, partial strong factorial, and partial strict factorial invariance and cross-cultural configural and partial metric invariance supported the cross-cultural equivalence of the EIS versions. Moreover, the external validity of the translated EIS responses was also supported. Overall, the findings supported the validity of the exercise identity construct outside North American boundaries and the EIS items' equivalence, providing initial evidence for its cross-cultural applicability.  相似文献

Laboratory versus field testing in cricket bowling: A review of current and past practice in modelling techniques     

Bruce Elliott  Jacqueline Alderson 《Sports biomechanics / International Society of Biomechanics in Sports》2013,12(1):99-108

In cricket bowling, the reconstruction of elbow angle data is of utmost importance to the bowling versus throwing argument. This paper reviews system and modelling errors inherent in three-dimensional reconstruction processes with respect to the elbow extension tolerance set by the International Cricket Council. An understanding of these factors will enable more informed decisions about the choice of in-field versus laboratory testing in the calculation of elbow extension during bowling in cricket. Although there is a paucity of objective data related to in-field and laboratory testing, biomechanists must be guided by the greater accuracy of opto-reflective than video-based systems and so testing, at least for the present, should be conducted in a laboratory setting.  相似文献
