This paper describes a partnership between a university and an urban school district, formed with a goal of preparing mathematics teacher leaders to conduct professional development (PD) at their schools. The university and district partners worked together to achieve the district’s mission of providing every student with high-quality instruction and equitable learning opportunities in mathematics by building the district’s capacity to conduct school-based PD for mathematics teachers. Given the power of school-based subject-specific PD for improving instructional quality, we worked with Teacher Leaders from participating schools to prepare and support them to lead PD workshops at their schools. In this paper, we examine how Teacher Leaders learn and adapt key elements of a PD model over three school years through the lenses of Prediger et al.’s Three-Tetrahedron-Model (2019) and the university’s Learning to Lead model. Over 3 years, we see that Teacher Leaders use the key structures of the PD model; make adaptations in response to school goals, interests, and priorities; and gain confidence in their work with colleagues. By viewing the adaptations through the lens of pedagogies of practice as well as the relationships illustrated by the 3-T model, this work offers insights into the complexities of teacher leadership development.

Analogy motor learning by young children: a study of rope skipping     

Andy C. Y. Tse  Shirley S. M. Fong  Thomson W. L. Wong  Rich Masters 《European Journal of Sport Science》2017,17(2):152-159

Research in psychology suggests that provision of an instruction by analogy can enhance acquisition and understanding of knowledge. Limited research has been conducted to test this proposition in motor learning by children. The purpose of the present study was to examine the feasibility of analogy instructions in motor skill acquisition by children. Thirty-two children were randomly assigned to one of the two instruction protocols: analogy and explicit instruction protocols for a two-week rope skipping training. Each participant completed a pretest (Lesson 1), three practice sessions (Lesson 2–4), a posttest and a secondary task test (Lesson 5). Children in the analogy protocol displayed better rope skip performance than those in the explicit instruction protocol (p?<?.001). Moreover, a cognitive secondary task test indicated that children in the analogy protocol performed more effectively, whereas children in the explicit protocol displayed decrements in performance. Analogy learning may aid children to acquire complex motor skills, and have potential benefits related to reduced cognitive processing requirements.  相似文献

Cushioning and lateral stability functions of cloth sport shoes     

Fong DT  Hong Y  Li JX 《Sports biomechanics / International Society of Biomechanics in Sports》2007,6(3):407-417

In this study, we evaluated the protective functions of cloth sport shoes, including cushioning and lateral stability. Twelve male students participated in the study (mean +/- s: age 12.7 +/- 0.4 years, mass 40.7 +/- 5.9kg, height 1.50 +/- 0.04m). Cloth sport shoes, running shoes, basketball shoes, crosstraining shoes, and barefoot conditions were investigated in random sequence. Human pendulum and cutting movement tests were used to assess cushioning performance and lateral stability, respectively. For cushioning, the running shoes (2.06 body weight, BW) performed the best, while the cross-training shoes (2.30 BW) and the basketball shoes (2.37 BW) both performed better than the cloth sport shoes (2.55 BW) and going barefoot (2.63 BW). For the lateral stability test, range of inversion--eversion was found to be from 3.6 to 4.9 degrees, which was far less than that for adult participants (> 20 degrees). No significant differences were found between conditions. All conditions showed prolonged durations from foot-strike to maximum inversion (66-95 ms), which was less vigorous than that for adult participants (< 40 ms) and was unlikely to evoke intrinsic stability failure. In conclusion, the cloth sport shoe showed inferior cushioning capability but the same lateral stability as the other sports shoes for children.  相似文献

Managing change in an integrated school--a Hong Kong hybrid experience     

Pattie Luk Fong Yuk Yee 《International Journal of Inclusive Education》2013,17(1):89-103

Following the world trend of inclusion in education, many schools in Hong Kong have started including students with special needs in the regular classrooms. Given the unique educational context of Hong Kong as 'East meets West', and given that inclusion is essentially a concept from the West, this paper argues that Hong Kong's integration has its unique hybrid features. This paper reports the experience of one primary school in the process of change in areas of stages of integration, leadership and whole school approach, during a two-year implementation period. Change processes at the school, classroom and individual levels are discussed. A case study methodology is used so that unique characteristics of the school in its naturalistic settings can be captured. Data were obtained from observation, documentary analysis, individual and group interviews of different school stakeholders: the principals, parents, teachers, resource teachers, and guidance personnel. Implications of findings to schools in Hong Kong and other countries facing similar issue in parallel and mixed cultural settings are discussed.  相似文献   

New Model,New Strategies: Instructional design for building online wisdom communities     

Charlotte N. Gunawardena  Ludmila Ortegano‐Layne  Kayleigh Carabajal  Casey Frechette  Ken Lindemann  Barbara Jennings 《Distance Education》2006,27(2):217-232

We discuss the development of an instructional design model, WisCom (Wisdom Communities), based on socio‐constructivist and sociocultural learning philosophies and distance education principles for the development of online wisdom communities, and the application and evaluation of the model in an online graduate course in the USA. The WisCom model aims to facilitate transformational learning by fostering the development of a wisdom community, knowledge innovation, and mentoring and learner support in an online learning environment, based on a “Cycle of Inquiry” module design, and a “Spiral of Inquiry” program design. Extending beyond current instructional design practice, WisCom provides both a new model for teaching that builds upon the inherent capacity of networked communication to support the growth and intellectual development of communities of practice, and a new model of learning where learners engage in the process of scholarly inquiry that supports individual and collective learning. Evaluation and research data support the WisCom model's ability to design a learning community engaged in the collaborative construction of knowledge.  相似文献

Genetics in medical school curriculum： A look at the University of Rochester School of Medicine and Dentistry     

Robinson DM  Fong CT 《Journal of Zhejiang University. Science. B》2008,9(1):10-15

Genetics is assuming an increasingly important role in medicine. As a result, the teaching of genetics should also be increased proportionally to ensure that future physicians will be able to take advantage of the new genetic technology, and to understand the associated ethical, legal and social issues. At the University of Rochester School of Medicine and Dentistry, we have been able to incorporate genetic education into a four-year medical curriculum in a fully integrated fashion. This model may serve as a template for other medical curriculum still in development.  相似文献   

Sources of self-efficacy of community college students enrolled in developmental mathematics     

Linda Reichwein Zientek  Carlton J. Fong  Julie M. Phelps 《Journal of Further & Higher Education》2019,43(2):183-200

The need to improve student success in community colleges has resulted in a growing interest in developmental mathematics. Yet there remains a need to understand the motivations and beliefs of developmental mathematics students in order to cultivate their success. Self-efficacy has been identified to be a predictor of student success. Little is known about the antecedents or sources of self-efficacy of students enrolled in remedial courses at community colleges and how their self-efficacy can be bolstered through such courses. An instrument was developed to measure sources of mathematics self-efficacy and was originally tested with middle school students. Using a sample of 439 students, it was found that a scale which measures sources of self-efficacy is psychometrically acceptable for adults completing mathematics remediation. Our results indicated that the four theorised sources of self-efficacy explained a large percentage of the variance in mathematics skill self-efficacy for our sample. As hypothesised by others, mastery experiences was the best predictor of self-efficacy but all sources influenced mathematics skills self-efficacy.  相似文献
