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

Der Beitrag diskutiert aus der Perspektive historischer Sozialisationsforschung gegenw?rtige Bilder vom Kind. Er skizziert
die Grundzüge des romantischen Kindheitsmythos um 1800 und analysiert seine Kontinuit?ten in der P?dagogik um 1900 und an
der Wende zum 21. Jahrhundert. Er zeigt, dass sowohl dem aktuellen Bestseller von Elschenbroich „Das Weltwissen der Siebenj?hrigen“ (2001), als auch Positionen der zeitgen?ssischen Kindheitsforschung durchaus romantische
Elemente zugrunde liegen. Kritisch befragt werden in diesem Zusammenhang sowohl das Konzept der „Selbstsozialisation“, als
auch die Annahme vom Verschwinden der Differenz zwischen Kindern und Erwachsenen. Der Beitrag endet mit einem Fazit, in dem
Gründe für die Attraktivit?t des Kindheitsmythos aufgeführt sowie Forschungsfragen und -probleme er?rtert werden. 相似文献

In order to give an idea of the present situation of education in Mayan communities, the article starts with a survey of published anthropologocal and educational information on the content, values and methods of education in indigenous communities in Guatemala. The second part deals with the formation of a new collective identity in Guatemala, exploring the relationship between the recent debate on Mayan identity, and Mayan education. Finally, attention is given to the relationship between education in indigenous communities and official, formal education, which is itself being called into question. Mayan education in Guatemala is not only a historical tradition which has survived centuries of alien domination, but is also a forceful voice of criticism in the debate about general educational reform. 相似文献

Detection of neuro-muscular fatigue in strength training is difficult, due to missing criterion measures and the complexity of fatigue. Thus, a variety of methods are used to determine fatigue. The aim of this study was to use a principal component analysis (PCA) on a multifactorial data-set based on kinematic measurements to determine fatigue. Twenty participants (strength training experienced, 60% male) executed 3 sets of 3 exercises with 50 (12 repetitions), 75 (12 repetitions) and 100%-12 RM (RM). Data were collected with a 3D accelerometer and analysed by a newly developed algorithm to evaluate parameters for each repetition. A PCA with six variables was carried out on the results. A fatigue factor was computed based on the loadings on the first component. One-way ANOVA with Bonferroni post hoc analysis was calculated to test for differences between the intensity levels. All six input variables had high loadings on the first component. The ANOVA showed a significant difference between intensities (p < 0.001). Post-hoc analysis revealed a difference between 100% and the lower intensities (p < 0.05) and no difference between 50 and 75%-12RM. Based on these results, it is possible to distinguish between fatigued and non-fatigued sets of strength training. 相似文献

The adaptive use of strategies, that is selecting a strategy which allows an efficient solution for a given problem, can be considered as an important individual ability relevant in various domains. Based on models of subjects’ skills of adaptive use of strategies, two idealized instructional approaches are suggested to foster students in their strategy development. The explicit approach aims at reducing cognitive load by demonstrating and practicing strategies combined with an explicit identification of criteria for strategy efficiency by contrasting problem solutions. The implicit approach capitalizes on the generation effect and stimulates students to generate their own strategies and efficiency criteria based on the analysis of task characteristics and the comparison of problem solutions. In a 1-week experimental study (16 lessons) with 73 third-graders, we examined the effectiveness of these instructional approaches in the domain of multi-digit addition and subtraction. Results from post- and two follow-up tests after 3 and 8?months did not yield different effects of the two approaches on students’ skills in adaptive use of strategies. A comparison of strategies used by the students showed that the students of the explicit approach more frequently applied complex strategies whereas the students from the implicit approach showed a more sustainable use of self-generated strategies. Hence, for the adaptive use of those strategies students are able to generate, the implicit approach turned out to be more effective than the explicit approach. However, this generation effect does not hold for strategies which are too complex to be generated by students. 相似文献

Abstract Based on a conceptual framework, that describes the relationship between the effectiveness of up-scaling participation and implementing decentralisation, the objective of this paper is to analyse the effectiveness of decentralisation measures in the Agricultural Technology System (ATS) of Vietnam. It discusses whether the decentralisation efforts so far have enabled the rural population to express their options and take joint decisions in the sense of participation. The paper uses primary and secondary data, collected between November 2000 and June 2001. The paper first discusses the theoretical literature on up-scaling participation and decentralisation. Emphasis is given to highlight the links between the concepts of good governance in decentralisation and its effects on people's participation in the decision making process. Thereafter, the Vietnamese decentralisation measures are reviewed and it is assessed to which extent the agricultural sector and its relevant state agencies have benefited from these efforts. The experiences from the decentralisation activities is summarised. Whether decentralisation opened space for the rural people to express their opinions and to ensure that their preferences are incorporated in the ATS is specially considered. The paper closes with recommendations. 相似文献

Bilingual publishing has become a strategy employed by journals from the non‐Anglophone world to gain wider recognition. Beyond anecdotal evidence, however, there are no published accounts of the experiences of editors and authors of bilingual journals with the process of bilingual publication. It is also unclear how authors writing in bilingual journals judge the quality of the translations and whether they consider this sort of publishing as beneficial for their aims. Consequently, we carried out two surveys: one among editors of bilingual journals and one anonymous survey among authors and translators of articles published in Deutsches Ärzteblatt International, the bilingual journal of the German Medical Association. Eight of nine journals as well as 233 of 353 authors and 4 of 6 translators took part. Most journals reported that bilingual publication helped in becoming indexed in important databases (e.g. Medline), receiving or improving an Impact Factor, and in attracting authors. All journals plan to continue publishing bilingually. Authors were ‘satisfied’ (40.8%) or ‘very satisfied’ (57.8%) with translations. Almost all (96.7%) were in favour of bilingual publication of their work. They did not view an English translation as an obstacle to another related English language paper. Translators highlighted challenges relating to specialized terminology and to terms specific to the regional healthcare system. 相似文献

The article takes its starting point from the current debate on sexual violence in educational institutions. It follows an ethnographic perspective without observing sexual violence directly, arguing that doing so is ethically impossible. Instead it suggests deducing risks for sexual violence through the limits of pedagogical practices. Discussing two case studies (an all-day-school and a residential child care home) and relating their discursive concepts of caring and educating to their practices shows how these institutions address the topic of sexual violence. Reconstructing the practices that constitute a difference between exclusive, one-on-one caring situations and open, publicly accessible educational situations show how transgressions of the limits of corporality to intimacy become institutionalised. We conclude that an ethnography of transgression points to practice arrangements that pose a risk for sexual violence in educational institutions. 相似文献

Purpose: Meat processing companies have the potential to raise farm and sector productivity by directly working with farmers. This study assesses how commercial companies can undertake the roles of innovation intermediaries to increase productivity in New Zealand’s sheep and beef sector.
Design/methodology/approach: This study uses a case study approach from the red meat sector in New Zealand. The case study included the development of a trial agricultural extension system established by staff from meat processing companies acting as innovation intermediaries, providing opportunities for skill development and knowledge transfer for farmers. From the case study, a framework is developed which illustrates how company staff can undertake the role of an innovation intermediary.
Findings: (1) Meat processing company staff are able to successfully undertake the role of an innovation intermediary; (2) flexibility is necessary, as staff undertook each of the functions to different degrees depending on their existing skills and knowledge of agricultural extension and the time available within their current job; and (3) adaptability is important, as staff adapted the project to meet the needs of both farmers and their employer.
Practical implications: Balancing commercial and extension roles is challenging. The framework could assist companies to clarify how individual company staff could successfully undertake specific roles.
Theoretical implications: This paper discusses factors influencing which innovation intermediary roles and functions are optimally undertaken by staff within or outside a meat processing company.
Originality/value: Analysing the role of an innovation intermediary from the perspective of meat processing company staff balancing their extension and commercial role. 相似文献

This study aimed to analyse the effects of two factors (number of players and training regimes) on players’ physiological and technical demands in basketball ball-drills. Twenty-one young basketball players performed four different ball-drills (two levels for each factor). The number of players involved was 2vs2 and 4vs4, while ball-drill regimes were continuous and intermittent. Physiological demand was assessed using the percentage of maximal heart rate (%HRmax), Edwards’ training load and rating of perceived exertion (RPE). Furthermore, the following technical actions were collected: dribbles, steals, rebounds, turnovers, passes (total, correct, wrong and % of correct pass) and shots (total, scored, missed and % of made shot). A 2 × 2 (number of players × regime) two-way ANOVA with repeated measures was applied for physiological parameters and technical actions. The 2vs2 condition showed higher %HRmax (P < 0.001), Edwards’ training load (P < 0.001), RPE (P < 0.001), number of dribbles (P < 0.001), rebounds (P < 0.001), passes [total (P = 0.005) and correct (P = 0.005)] and shots [total (P < 0.001) scored (P < 0.001) and missed (P < 0.001)] than 4vs4. Moreover, the continuous regime revealed higher %HRmax (P < 0.001), Edwards’ training load (P < 0.001), RPE (P = 0.006) and dribbles (P < 0.001) than the intermittent regime. This study showed that both number of players and regime are useful variables able to modify basketball ball-drills workload. 相似文献
