The Science Teachers Learning from Lesson Analysis (STeLLA) project is a videobased analysis‐of‐practice PD program aimed at improving teacher and student learning at the upper elementary level. The PD program developed and utilized two “lenses,” a Science Content Storyline Lens and a Student Thinking Lens, to help teachers analyze science teaching and learning and to improve teaching practices in this year‐long program. Participants included 48 teachers (n = 32 experimental, n = 16 control) and 1,490 students. The STeLLA program significantly improved teachers' science content knowledge and their ability to analyze science teaching. Notably, the STeLLA teachers further increased their classroom use of science teaching strategies associated with both lenses while their students increased their science content knowledge. Multi‐level HLM analyses linked higher average gains in student learning with teachers' science content knowledge, teachers' pedagogical content knowledge about student thinking, and teaching practices aimed at improving the coherence of the science content storyline. This paper highlights the importance of the science content storyline in the STeLLA program and discusses its potential significance in science teaching and professional development more broadly. © 2011 Wiley Periodicals, Inc., J Res Sci Teach 48: 117–148, 2011  相似文献   

The microfluidic system for studies of carcinoma and normal cells interactions after photodynamic therapy (PDT) procedures     

Jedrych E  Chudy M  Dybko A  Brzozka Z 《Biomicrofluidics》2011,5(4):41101-411016

This study reports on the use of a microsystem for evaluation of photodynamic therapy (PDT) procedures on the "mixed" (carcinoma-normal) cultures. Balb/3T3 (normal mouse embryo) and A549 (human lung carcinoma) cells were tested in separated and "mixed" cultures. Interactions and migration of cells cultured together were observed. The PDT procedures were examined in the hybrid (PDMS/glass) microsystem which contains cell culture microchambers integrated with network of microchannels. We investigated that the number of dead cells after PDT procedures is dependent on the kind of cell culture. Moreover, the influence of the carcinoma cells on the viability of normal cells in the "mixed" culture was observed.  相似文献   

The effect of patellar taping on EMG activity of vasti muscles during squatting in individuals with patellofemoral pain syndrome     

Mostamand J  Bader DL  Hudson Z 《Journal of sports sciences》2011,29(2):197-205

Although patellar taping has been shown to reduce pain in participants with patellofemoral pain syndrome, the mechanisms of pain reduction have not completely been established following its application. The purpose of this study was to evaluate EMG activity of vastus medialis and vastus lateralis following the application of patellar taping during a functional single leg squat. Both vastus medialis obliquus-vastus lateralis onset and vastus medialis obliquus/vastus lateralis amplitude of 18 participants with patellofemoral pain syndrome and 18 healthy participants as controls were measured using an EMG unit. This procedure was performed on the affected knee of participants with patellofemoral pain syndrome, before, during, and after patellar taping during unilateral squatting. The same procedure was also performed on the unaffected knees of both groups. The mean values of vastus medialis obliquus-vastus lateralis onset prior to taping (2.54 ms, s = 4.35) were decreased significantly following an immediate application of tape (-3.22 ms, s = 3.45) and after a prolonged period of taping (-6.00 ms, s = 3.40 s) (P < 0.05). There was also a significant difference between the mean values of vastus medialis obliquus-vastus lateralis onset among controls (-2.03 ms, s = 6.04) and participants with patellofemoral pain syndrome prior to taping (P < 0.05). However, there were no significant difference between the ranked values of vastus medialis obliquus/vastus lateralis amplitude of the affected and unaffected knees of participants with patellofemoral pain syndrome and controls during different conditions of taping (P > 0.05). Decreased values of vastus medialis obliquus-vastus lateralis onset may contribute to patellar realignment and explain the mechanism of pain reduction following patellar taping in participants with patellofemoral pain syndrome.  相似文献   

论艺术教育的意义与价值     

凯瑟琳·埃尔金  洪瑞祥 《清华大学教育研究》2022,43(1):1-11

社会上存在很多对艺术教育的迷思,比如,艺术与教育的关系是什么?艺术是否可教?艺术完全是灵感的产物吗?艺术是否值得被教?艺术教育的作用是什么?符号理论可以表明艺术教育的可行性及价值。我们不应该将艺术仅仅视为达成某一具体目的的手段,而应该将其既看作目的,又视为手段。艺术完全是灵感的产物这一假设是没有根据的,学生的感觉回应和情感反应可以被教育,艺术教育是可能的,也是有价值的。  相似文献

THE NATURE OF COUNSELLING     

Hans Z. Hoxter 《Higher Education in Europe》1994,19(3):7-9

The counsellor functions in a broad spectrum verging upon psychotherapy at one boundary and upon advice giving at the other and may also enrich the skills of others in the caring professions. In all cases, receptivity to the individual's thoughts and feelings is required. This capacity is enlarged by the counsellor's ability to extend his or her own self‐understanding and by willingness to learn from the client.  相似文献
