Effects of Web-based Support for the Construction of Competence Maps     

Angela Stoof  Rob L. Martens  Jeroen J. G. van Merriënboer 《Instructional Science》2006,34(3):189-211

Educationalists experience difficulties with the construction of competence maps that describe final attainment levels of educational programs. Web-based support was developed with three supportive aids: A construction kit, a phenomenarium, and an information bank. Each supportive aid was expected to improve perceived process and product quality as well as learning. In a full factorial experiment, 266 educational science students constructed a competence map, whether or not supported by different combinations of the three supportive aids. The availability of the construction kit and the phenomenarium had positive effects on perceived process quality and learning. Furthermore, if there was no phenomenarium with example materials, the absence of the construction kit greatly diminished experienced support (i.e., one aspect of process quality); if a phenomenarium was present, the availability of the construction kit had relatively little effect on perceived support. In general, this study indicates that well-designed Web-based support helps to construct competence maps. in final form: 2 February 2006  相似文献   

‘Question Moments’: A Rolling Programme of Question Opportunities in Classroom Science     

Helena Pedrosa-de-Jesus  Sara Leite  Mike Watts 《Research in Science Education》2016,46(3):329-341

This naturalistic study integrates specific ‘question moments’ into lesson plans to increase pupils’ classroom interactions. A range of tools explored students’ ideas by providing students with opportunities to ask and write questions. Their oral and written outcomes provide data on individual and group misunderstandings. Changes to the schedule of lessons were introduced to explore these questions and address disparities. Flexible lesson planning over 14 lessons across a 4-week period of high school chemistry accommodated students’ contributions and increased student participation, promoted inquiring and individualised teaching, with each teaching strategy feeding forward into the next.  相似文献

Evaluating the quality of e-learning at the degree level in the student experience of blended learning     

Paul Ginns  Rob A. Ellis 《British journal of educational technology : journal of the Council for Educational Technology》2009,40(4):652-663

This paper reports on the development of a scale for determining the quality of the student e-learning experience at the degree level when the student learning context is predominately a campus-based experience. Rapid developments in the use of information and communication technologies (ICT) in higher education require methods for evaluating the contribution of such tools to student learning, especially when they are complementing a face-to-face experience. We examine the psychometric functioning of a proposed e-learning scale in relation to a well-validated degree-level teaching evaluation instrument, the Student Course Experience Questionnaire. The e-learning scale has suitable reliability and validity in the present sample of undergraduate students for quality assurance activities around ICT.  相似文献

School funding formulae: designed to create a learning society?     

Iris BenDavid-Hadar  Stephoni Case  Rob Smith 《Compare》2018,48(4):553-570

The right to education depends upon a willingness to finance education fairly. Addressing the difference in educational achievement between learners of different backgrounds is a key aspect of fairness. Framed by contemporary neoliberal policies around marketisation and competitiveness, this paper examines fairness in the education finance policy (EFP) of three jurisdictions in England, Israel and Oklahoma. Using a comparative analysis of school funding formulae and an international survey on the perceptions of local policy actors, the de jure and the de facto EFPs are examined. Our findings reveal de jure policies attempting to address fairness through integrating different student background characteristics. However, variability is evident in the extent to which the de facto policies align with an aspiration for fairness. This is linked to the marketisation of education in each jurisdiction. We conclude that weightings of students’ background characteristics can only be one feature in policy interventions orientated towards bringing about social equity.  相似文献   

Comparison of kinematics in skilled and unskilled arms of the same recreational baseball players     

S. Gray  S. Watts  D. Debicki 《Journal of sports sciences》2013,31(11):1183-1194

Abstract

We examined mechanisms of coordination that enable skilled recreational baseball players to make fast overarm throws with their skilled arm and which are absent or rudimentary in their unskilled arm. Arm segment angular kinematics in three dimensions at 1000 Hz were recorded with the search-coil technique from the arms of eight individuals who on one occasion threw with their skilled right arm and on another with their unskilled left arm. Compared with their unskilled arm, the skilled arm had: a larger angular deceleration of the upper arm in space in the forward horizontal direction; a larger shoulder internal rotation velocity at ball release (unskilled arms had a negative velocity); a period of elbow extension deceleration before ball release; and an increase in wrist velocity with an increase in ball speed. It is suggested that some of these differences in arm kinematics occur because of differences between the skilled and unskilled arms in their ability to control interaction torques (the passive torque at one joint due to motion at adjacent joints). It is proposed that one reason unskilled individuals cannot throw fast is that, unlike their skilled counterparts, they have not developed the coordination mechanisms to effectively exploit interaction torques.  相似文献

Adjusting athletes' body mass index to better reflect adiposity in epidemiological research     

Alan M. Nevill  Edward M. Winter  Steve Ingham  Adam Watts  Georgios S. Metsios  Arthur D. Stewart 《Journal of sports sciences》2013,31(9):1009-1016

Abstract

The aim of the present study was to identify when body mass index (BMI) is unlikely to be a valid measure of adiposity in athletic populations and to propose a simple adjustment that will allow the BMI of athletes to reflect the adiposity normally associated with non-athletic populations. Using data from three previously published studies containing 236 athletes from seven sports and 293 age-matched controls, the association between adiposity (sum of 4 skinfold thicknesses, in millimetres) and BMI was explored using correlation, linear regression, and analysis of covariance (ANCOVA). As anticipated, there were strong positive correlations (r = 0.83 for both men and women) and slope parameters between adiposity and BMI in age-matched controls from Study 1 (all P < 0.001). The standard of sport participation reduced these associations. Of the correlations and linear-regression slope parameters between adiposity and BMI in the sports from Studies 2 and 3, although still positive in most groups, less than half of the correlations and slope parameters were statistically significant. When data from the three studies were combined, the ANCOVA identified that the BMI slope parameter of controls (5.81 mm · (kg · m^?2)^?1) was greater than the BMI slope parameter for sports (2.62 mm · (kg · m^?2)^?1) and middle-distance runners (0.94 mm · (kg · m^?2)^?1) (P < 0.001). Based on these contrasting associations, we calculated how the BMI of athletes can be adjusted to reflect the same adiposity associated with age-matched controls. This simple adjustment allows the BMI of athletes and non-athletes to be used with greater confidence when investigating the effect of BMI as a risk factor in epidemiological research.  相似文献
