Although rapid advances in technology has allowed for the growth of collaborative e-learning experiences unconstrained by time and space, technology has not been heavily infused in the activities of teaching and learning. This article examines the theory of constructivism as well as the design of e-learning activities using constructivist principles. The manner in which constructivist theory supports e-Learning is explored, and extrapolating from this pedagogical theory, some implications are provided to model effective practices of the characteristics and capacities of this powerful learning environment. 相似文献

The purpose of this investigation was to compare valgus/varus knee angles during various jumps and lower body strength between males and females relative to body mass. Seventeen recreationally active females (age: 21.94 ± 2.59 years; height: 1.67 ± 0.05 m; mass: 64.42 ± 8.39 kg; percent body fat: 26.89 ± 6.26%; squat one-repetition maximum: 66.18 ± 19.47 kg; squat to body mass ratio: 1.03 ± 0.28) and 13 recreationally active males (age: 21.69 ± 1.65 years; height: 1.77 ± 0.07 m; mass: 72.39 ± 9.23 kg; percent body fat: 13.15 ± 5.18%; squat one-repetition maximum: 115.77 ± 30.40 kg; squat to body mass ratio: 1.59 ± 0.31) performed a one-repetition maximum in the squat and three of each of the following jumps: countermovement jump, 30 cm drop jump, 45 cm drop jump, and 60 cm drop jump. Knee angles were analysed using videography and body composition was analysed by dual-energy X-ray absorptiometry to allow for squat to body mass ratio and squat to fat free mass ratio to be calculated. Significant differences (P ≤ 0.05) were found between male and female one-repetition maximum, male and female squat to body mass ratio, and male and female squat to fat free mass ratio. Significant differences were found between male and female varus/valgus knee positions during maximum flexion of the right and left leg in the countermovement jump, drop jump from 30 cm, drop jump from 45 cm, and drop jump from 60 cm. Correlations between varus/valgus knee angles and squat to body mass ratio for all jumps displayed moderate, non-significant relationships (countermovement jump: r = 0.445; drop jump from 30 cm: r = 0.448; drop jump from 45 cm: r = 0.449; drop jump from 60 cm: r = 0.439). In conclusion, males and females have significantly different lower body strength and varus/valgus knee position when landing from jumps. 相似文献

ABSTRACTIn preparing the future stewards of the physical education profession, the occupational socialization and professional development of physical education doctoral students is important to consider. To date, there has been scant scholarly inquiry into doctoral education in physical education. However, there is an abundance of research related to doctoral training in the higher education literature more generally. Drawing upon this larger body of work, this article expands occupational socialization theory to address the socialization of physical education doctoral students and faculty members. The case is made that effective doctoral training in physical education is essential to securing the future of the profession. Provided is an overview of the existing literature, presentation of an adaptation to occupational socialization theory that explains doctoral physical education socialization, and a discussion of key professional development issues that academic leaders and student support personnel should consider. Implications and recommendations for doctoral physical education leadership and academic programs are provided. 相似文献

Self-assessment is essential to scientific literacy as stated by the National Research Council Committee on Conceptual Framework for the New K-12 Science Education Standards and has since been incorporated into the Next Generation Science Standards. However, little empirical evidence documents which instructional tools are beneficial in improving students’ self-assessment in science learning. As such, we conducted a classroom-based quasi-experiment to test whether contrasting case-based instructional supports improved 390 introductory high school physics students’ accuracy in self-assessment and academic performance when solving physics problems. We compared the effects of providing students with content knowledge and contrasting cases (contrasting good and poor solution) on students’ physics problem solving and their ability to self-assess, with the effects of either presenting them with content knowledge and good solutions or teaching only content knowledge. We found contrasting examples improved the accuracy of students’ self-assessments, promoted content learning, and enhanced the development of self-assessment strategies. 相似文献

To investigate the effects of different loads on system and lower-body kinetics during jump squats, 12 resistance-trained men performed jumps under different loading conditions: 0%, 12%, 27%, 42%, 56%, 71%, and 85% of 1-repetition maximum (1-RM). System power output was calculated as the product of the vertical component of the ground reaction force and the vertical velocity of the bar during its ascent. Joint power output was calculated during bar ascent for the hip, knee, and ankle joints, and was also summed across the joints. System power output and joint power at knee and ankle joints were maximized at 0% 1-RM (p < 0.001) and followed the linear trends (p < 0.001) caused by power output decreasing as the load increased. Power output at the hip was maximized at 42% 1-RM (p = 0.016) and followed a quadratic trend (p = 0.030). Summed joint power could be predicted from system power (p < 0.05), while system power could predict power at the knee and ankle joints under some of the loading conditions. Power at the hip could not be predicted from system power. System power during loaded jumps reflects the power at the knee and ankle, while power at the hip does not correspond to system power. 相似文献

The authors conducted a survey of members of the American College Counseling Association to ascertain the experiences and opinions of college counselors on several pressing issues within the college counseling profession. Survey results from 133 respondents indicated that counseling centers may benefit from increasing the number of group counseling interventions by increasing the multicultural competence of services provided, by implementing crisis/disaster mental health initiatives, and by more effectively consulting with other professionals on campus. 相似文献

Three related studies replicated and extended previous work (J.A. Danielson et al. (2003), Educational Technology Research and Development, 51(3), 63–81) involving the Diagnostic Pathfinder (dP) (previously Problem List Generator [PLG]), a cognitive tool for learning
diagnostic problem solving. In studies 1 and 2, groups of 126 and 113 veterinary students, respectively, used the dP to complete
case-based homework; groups of 120 and 199, respectively, used an alternative method. Students in the dP groups scored significantly
higher (p = .000 and .003, respectively) on final exams than those in control groups. In the third study, 552 veterinary students responding
to a questionnaire indicated that the dP’s gating and data synthesis activities aided learning. The dP’s feedback and requirement
of completeness appear to aid learning most. 相似文献

ABSTRACT The purpose of the research reported in this paper was to investigate strategies to aid teachers in delivering the mathematical component of the English National Curriculum with the help of electronic databases and spreadsheets. It is widely realised within mathematics that information technology remains a relatively neglected part of the curriculum in some schools. The provision of short courses in using spreadsheets and databases as part of a traditional inservice package is often considered to be unsuccessful as a means of enabling teachers to deliver the material back in the classroom. It could be argued that for progress to be made, an expert must spend time working in situ in the school with the teacher(s). Clearly an expert cannot provide such support for every department that requires assistance, so there is a need to develop generally applicable strategies as a springboard for their own means. This paper reports on a case study designed to start the process of developing such strategies. 相似文献

Previous research has indicated that approach–avoidance motivation at the achievement goal level influences the quality of self-regulated learning. Additionally, research indicates that approach–avoidance motivation at the dispositional level is associated with cognitive self-regulated learning strategy use. The present investigation sought to extend this research by examining the relationship between approach–avoidance motivation at the dispositional level and metacognitive self-regulation, as well as the mediational potential of approach–avoidance achievement goals among a sample of undergraduate students (N = 145). Results indicated that need for achievement was significantly related to metacognitive self-regulation and mastery-approach goals partially mediated this relationship. Fear of failure was negatively associated with metacognitive self-regulation; however, performance-avoidance goals did not mediate this relationship. The significance of such individual differences in metacognitive self-regulation is discussed. 相似文献
