The development and application of affective assessment in an upper‐level cell biology course     

Elizabeth Kitchen  Suzanne Reeve  John D. Bell  Richard R. Sudweeks  William S. Bradshaw 《科学教学研究杂志》2007,44(8):1057-1087

This study exemplifies how faculty members can develop instruments to assess affective responses of students to the specific features of the courses they teach. Means for assessing three types of affective responses are demonstrated: (a) student attitudes towards courses with differing instructional objectives and methodologies, (b) student self‐efficacy (confidence) in completing tasks common to practicing experts, and (c) interests in subject‐specific topics and associated intellectual skills. The iterative processes used in refining the instruments and performing the statistical analyses of their effectiveness are detailed. An analysis of data obtained using these instruments is also included. Positive attitudes towards courses emphasizing analytical thinking increased significantly over the course of a 14‐week semester, as did the measures of self‐efficacy. Despite the rigorous analytical nature of the course experience, the initial strong interest in cell biology topics and higher order thinking skills remained unchanged. There were no significant differences based on gender in any of the affective measures. We discuss the apparent dichotomy, revealed in these assessments, between students' idealistic, academic attitudes towards the course's effectiveness and their opinions of its effects on them personally. We conclude by reporting how insights garnered both from these formal assessments and from anecdotal communications have prompted experimental modifications in the design and conduct of the course. © 2007 Wiley Periodicals, Inc.

Pre-service teachers’ engagement in a cross-curricular television news project: impact on professional identity     

Pete Bradshaw  Sarah Younie 《Teacher Development》2016,20(5):599-613

This paper focuses on the impact of pre-service teachers’ engagement in the annual BBC News School Report project on their emerging professional identity and on the evidence they provide as part of the process of becoming qualified. The research reported on is drawn from three years of enquiry. Respondents included pre-service teachers themselves, their tutors as representatives of teacher education providers and their mentors as representatives of schools in which they were placed. The methodological approach was interpretative and phenomenological with qualitative and quantitative data being analysed for emergent themes. Two years of evaluations were followed by a third year in which a set of case studies were developed. The research showed that professional identity is enhanced through being in a leading role in respect of curriculum and working with other staff. Through engagement in such projects, this paper moots that pre-service teachers develop richer evidence of emerging professionalism as defined by standards of initial teacher training. Moreover, self-perception of role was modified to one in which they saw themselves, and were seen, as equals to qualified staff rather than subservient to or dependent on them. A new more equal power relationship developed as they took on responsibility for the project. Pre-service teachers’ move to become full members of the professional community for which they are training was accelerated.  相似文献   

Handedness and the Development of Direction and Sequencing in Children's Drawings of People     

S. M. Glenn  K. Bradshaw  M. Sharp 《教育心理学》1995,15(1):11-21

The effect of age and handedness on directionality and sequence in drawing was studied in 389 right‐ and left‐handed children aged from 2 to 11 years. Preschool right‐handers were more likely to draw right to left and to produce circles in a clockwise direction. In contrast, preschool left handers drew left to right with anti‐clockwise circle production. By the age of 9 to 11 years right‐handers had switched to predominantly left to right drawing with anti‐clockwise circle production and left‐handers to right to left, drawing and clockwise circle production. Irrespective of handedness, preschool children tended to begin at the bottom of the drawing and work towards the top, whereas the older groups tended to draw from the top to the bottom. It is suggested that these rules of directionality and sequencing may influence how children respond to writing instruction.  相似文献   

An accurate VO2max nonexercise regression model for 18-65-year-old adults     

Bradshaw DI  George JD  Hyde A  LaMonte MJ  Vehrs PR  Hager RL  Yanowitz FG 《Research quarterly for exercise and sport》2005,76(4):426-432

The purpose of this study was to develop a regression equation to predict maximal oxygen uptake (VO2max) based on nonexercise (N-EX) data. All participants (N = 100), ages 18-65 years, successfully completed a maximal graded exercise test (GXT) to assess VO2max (M = 39.96 mL x kg(-1) x min(-1), SD = 9.54). The N-EX data collected just before the maximal GXT included the participant's age; gender; body mass index (BMI); perceived functional ability (PFA) to walk, jog, or run given distances; and current physical activity (PA-R) level. Multiple linear regression generated the following N-EX prediction equation (R = .93, SEE = 3.45 mL x kg(-1) x min(-1), % SEE = 8.62): VO2max (mL x kg(-1) x min(-1)) = 48.0730 + (6.1779 x gender; women = 0, men = 1) - (0. 2463 x age) - (0.6186 x BMI) + (0.7115 x PFA) + (0.6709 x PA-R). Cross validation using PRESS (predicted residual sum of squares) statistics revealed minimal shrinkage (R(p) = .91 and SEE(p) = 3.63 mL x kg(-1) x min(-1)); thus, this model should yield acceptable accuracy when applied to an independent sample of adults (ages 18-65 years) with a similar cardiorespiratory fitness level. Based on standardized beta-weights, the PFA variable (0.41) was the most effective at predicting VO2max followed by age (-0.34), gender (0.33), BMI (-0.27), and PA-R (0.16). This study provides a N-EX regression model that yields relatively accurate results and is a convenient way to predict VO2max in adult men and women.  相似文献

The assessment of adolescent female athletes using standing and reactive long jumps     

Mark P. Moresi  Elizabeth J. Bradshaw  David Greene  Geraldine Naughton 《Sports biomechanics / International Society of Biomechanics in Sports》2013,12(2):73-84

The aim of this study was to evaluate the reliability of two long jump tasks and their ability to predict 10 m sprint performance in elite adolescent female athletes. Eight junior national-level female track and field athletes completed three standing (SLJ) and reactive long jumps (RLJ) on portable force plates, followed by three 10 m sprints. Intra-class correlation coefficients (ICC) and coefficients of variation (CV) were calculated to examine reliability. Linear regression results identified the best predictor of average and best 10 m sprint time from the jump kinematic and kinetic measures. The ICCs and CVs indicated good reliability for the majority of kinetic measures however, better reliability was reported for the SLJ. The SLJ was a good predictor of best and average 10 m sprint time, with average horizontal power the best predictor of performance (best; R ² = 0.751, p = 0.003, Standard Error of Estimate (SEE)% = 2.2 average; R ² = 0.708, p = 0.005, SEE% = 2.5).  相似文献   

Biomechanical approaches to identify and quantify injury mechanisms and risk factors in women's artistic gymnastics     

Elizabeth J. Bradshaw  Patria A. Hume 《Sports biomechanics / International Society of Biomechanics in Sports》2013,12(3):324-341

Targeted injury prevention strategies, based on biomechanical analyses, have the potential to help reduce the incidence and severity of gymnastics injuries. This review outlines the potential benefits of biomechanics research to contribute to injury prevention strategies for women's artistic gymnastics by identification of mechanisms of injury and quantification of the effects of injury risk factors. One hundred and twenty-three articles were retained for review after searching electronic databases using key words, including ‘gymnastic’, ‘biomech*’, and ‘inj*’, and delimiting by language and relevance to the paper aim. Impact load can be measured biomechanically by the use of instrumented equipment (e.g. beatboard), instrumentation on the gymnast (accelerometers), or by landings on force plates. We need further information on injury mechanisms and risk factors in gymnastics and practical methods of monitoring training loads. We have not yet shown, beyond a theoretical approach, how biomechanical analysis of gymnastics can help reduce injury risk through injury prevention interventions. Given the high magnitude of impact load, both acute and accumulative, coaches should monitor impact loads per training session, taking into consideration training quality and quantity such as the control of rotation and the height from which the landings are executed.  相似文献
