This paper presents the results of a two-year research project aimed at developing a teacher professional development (TPD) model in Indonesia. New government policies in this nation, its archipelagic nature, vast numbers of teachers and scarcity of support resources present a unique challenge to TPD. A needs assessment was conducted to identify teachers’ professional needs. Based on the results of this assessment, a dual-mode TPD that combines face-to-face sessions and online sessions was developed. Participation in face-to-face sessions was relatively high but the participation rate in online sessions was very low. Incentives, teachers’ autonomy as professional learners, ICT skills and infrastructure are important considerations when designing TPD in Indonesia. This study and an analysis of TPD policy allow us to suggest future directions for TPD in Indonesia. 相似文献

In this study of the meanings of education and learning in people's lives, educational generations in Finland were investigated. The analysis is based on Karl Mannheim's concept and theory of social generation. This approach resulted in the differentiation of four educational cohorts living in contemporary Finnish society, three of which provided distinct core life experiences and educational experiences for analysis. These are: the war generation with scant education (born before 1935); the generation of structural change with growing educational opportunities (born 1936–55) and the welfare generation with many educational choices (born after 1955). This article, reviews the characteristics of these generations, and analyses the dynamics of their educational courses and experiences. It is concluded that their core experiences of education can be summarized in two basic narratives: the narrative of national culture and that of economic structural change. Finally, it is argued that such generational change reflects the more general rationalization of Western culture and society. Based on this argumentation, the future of adult education based on the application of Weberian social theory and its conceptions of material and formal rationality are considered. 相似文献

The purpose of the present study is to investigate the factors which affect attitudes towards multiculturalism among Jewish and Arab graduate students who experience intercultural learning in an Israeli-Jewish academic college of education. In Israeli society, it is in higher education institutions where young people from different ethnic groups first encounter the ‘others’. This is due to the structure of the Israeli elementary and secondary education system, which is divided into Jewish and Arab segregated sub-systems. In contrast, the country’s higher education institutions are open to everyone. The research population was composed of first and second year graduate students, all of whom were practicing teachers or involved in other educational work. Participants completed questionnaires and a smaller sample was also interviewed. All of the students are practicing teachers or involved in other educational work. Everyone perceived the college’s socio-cultural climate as an open and multicultural one in both years of study. However, these positive feelings characterized Jewish students to a larger extent than Arab students, while the socio-cultural aspect as well as the quality of the academic experience had a positive impact on multicultural attitudes primarily among Arab students. Thus, a multicultural climate is not enough to effect a positive change in entrenched attitudes toward multiculturalism. Multicultural education policy should also be reinforced through a formal academic curriculum, so as to set an example for ongoing social change which will further encourage graduate students—majority and minority alike—to implement their multicultural positive experiences in their own schools in the future. 相似文献

This study explores the context-dependent nature of organizational cognition and dynamic capabilities during strategic change. The empirical analysis is based on a quantitative survey conducted in the Finnish Broadcasting Company, Yleisradio. The theoretical frame is based on the concepts of dominant logic and the sensing, seizing, and configuring capacities of dynamic capabilities. The analysis indicates that Yleisradio’s sub-units differ in terms of change attitudes, capabilities, and future orientations. Some units have a stronger commitment to the new dominant logic than others; some are capable of changing faster than others. 相似文献

AbstractResearchers have shown an increased interest in the way teachers use their knowledge about language (KAL) to enhance student understanding and learning. This qualitative case study investigated first- and second-grade teachers’ use of KAL in Arabic. We investigated the linguistic transitions from standard Arabic to spoken Arabic made by the teachers during mathematics lessons. The results suggested that Arab-speaking mathematics teachers were aware of the gap between home language (Spoken Arabic) and school language (Modern Standard Arabic) and used linguistic transition as a teaching strategy to develop academic thinking and behaviour among their students. The results suggested that Arab teachers built a non-formal bilingual education programme where the two languages were used to teach mathematics. Despite the requirement to use Modern Standard Arabic, participants bridged the gap between the languages, which suggests an inherent understanding that ‘language and identity are ultimately inseparable’. 相似文献

The triple jump is a demanding field event in which a jumper must tolerate extremely high impact forces while maintaining high horizontal speed. The present study was designed to clarify the mechanical loading characteristics and the role of neuromuscular function in the triple jump. Seven national triple jumpers (4 males, 3 females) volunteered to perform 3-6 jumps. The mean best performances were 14.32 - 0.45 m and 11.90 - 0.28 m for males and females, respectively. The three longest triple jumps for each jumper were selected for final analysis. The mean contact times were 0.139 s (hop), 0.157 s (step) and 0.177 s (jump). The largest ground reaction forces were observed in the step (15.2 times body weight), while the highest peak pressures were recorded under the heel and forefoot. The plantar pressure of the lateral side of the forefoot was highly related to the length of the triple jump ( P ? 0.05-0.01). In addition, electromyograms of both legs suggested that mechanical loading places high demands on the neuromuscular system, as characterized by the high rate of activation in the pre-activity phase followed by high eccentric activity. Thus, the high activities of the gastrocnemius, vastus lateralis and hip extensor muscles seem to play an important role in preventing unnecessary yielding of the jumper during the braking phase. 相似文献

Abstract The aim of this study was to assess fatigue during a simulated cross-country skiing sprint competition based on skating technique. Sixteen male skiers performed a 30-m maximal skiing speed test and four 850-m heats with roller skies on a tartan track, separated by 20 min recovery between heats. Physiological variables (heart rate, blood lactate concentration, oxygen consumption), skiing velocity, and electromyography (EMG) were recorded at the beginning of the heats and at the end of each 200-m lap during the heats. Maximal skiing velocity and EMG were measured in the speed test before the simulation. No differences were observed in skiing velocity, EMG or metabolic variables between the heats. The end (820–850 m) velocities and sum-iEMG of the triceps brachii and vastus lateralis in the four heats were significantly lower than the skiing velocity and sum-iEMG in the speed test. A significant correlation was observed between mean oxygen consumption and the change in skiing velocity over the four heats. Each single heat induced considerable neuromuscular fatigue, but recovery between the heats was long enough to prevent accumulation of fatigue. The results suggest that the skiers with a high aerobic power were less fatigued throughout the simulation. 相似文献

AbstractThe study examined the acute neuromuscular and metabolic responses and recovery (24 and 48 h) to combined strength and endurance sessions (SEs). Recreationally endurance trained men (n = 12) and women (n = 10) performed: endurance running followed immediately by a strength loading (combined endurance and strength session (ES)) and the reverse order (SE). Maximal strength (MVC), countermovement jump height (CMJ), and creatine kinase activity were measured pre-, mid-, post-loading and at 24 and 48 h of recovery. MVC and CMJ were decreased (P < 0.05) at post-ES and SE sessions in men. Only MVC decreased in ES and SE women (P < 0.05). During recovery, no order differences in MVC were observed between sessions in men, but MVC and CMJ remained decreased. During recovery in women, a delayed decrease in CMJ was observed in ES but not in SE (P < 0.01), while MVC returned to baseline at 24 h. Creatine kinase increased (P < 0.05) during both ES and SE and peaked in all groups at 24 h. The present combined ES and SE sessions induced greater neuromuscular fatigue at post in men than in women. The delayed fatigue response in ES women may be an order effect related to muscle damage. 相似文献
