This paper presents a research-based teaching-learning sequence (TLS) that focuses on the notion of interaction in teaching Newton’s third law (N3 law) which is, as earlier studies have shown, a challenging topic for students to learn. The TLS made systematic use of a visual representation tool—an interaction diagram (ID)—highlighting interactions between objects and addressing the learning demand related to N3 law. This approach had been successful in enhancing students’ understanding of N3 law in pilot studies conducted by teacher-researchers. However, it was unclear whether teachers, who have neither been involved with the research nor received intensive tutoring, could replicate the positive results in ordinary school settings. To address this question, we present an empirical study conducted in 10 Finnish upper secondary schools with students (n?=?261, aged 16) taking their mandatory physics course. The study design involved three groups: the heavy ID group (the TLS with seven to eight exercises on IDs), the light ID group (two to three exercises on IDs) and the no ID group (no exercises on IDs). The heavy and light ID groups answered eight ID questions, and all the students answered four questions on N3 law after teaching the force concept. The findings clearly suggest that systematic use of the IDs in teaching the force concept significantly fostered students’ understanding of N3 law even with teachers who have no intensive tutoring or research background. 相似文献

This article introduces an international and interdisciplinary summer school, ‘Living in the Landscape’ (LiLa) in 2018. LiLa's practices focused on creating dialogue among art education, anthropology and nature science and developing culturally sustainable methods for investigating cultural heritage in the Komi Republic of Russia. The article's research interest is how dialogue and cultural heritage appear in the artistic processes, artworks and final exhibition of the summer school. These are examined through art‐based action research in order to develop international, multidisciplinary and culturally sustainable art education. The four‐field model utilised in the research highlights the multidimensional role of dialogue in both individual and collaborative artistic endeavours. 相似文献

Previous research has identified numerous obstacles that counteract attempts to involve pupils in democratic processes in schools. Drawing from deliberative democratic theory and sociolinguistic research on dialogic teaching we discuss an intervention grounded on the ideas of deliberative communication and decision-making in an elementary classroom in Finland. We show that deliberative communication can provide pupils with opportunities for democratic participation. This process involves altering conventional classroom interactional patterns and the power processes they uphold. The possibilities of expanding deliberative communication from isolated democratic meetings to everyday schooling are considered. 相似文献

Despite the large volume of research and managerial literature on knowledge management, many practitioners seem to find it difficult to appreciate its added value for their managerial work. This paper aims to understand and elaborate the added value that knowledge management as a managerial approach can bring to the management of knowledge-intensive organizations. This study explores empirically the actual management practices of a knowledge-intensive organization and examines how knowledge-related phenomena are managed as embedded aspects of management. This paper makes a contribution to prior discussions concerning the relevance of knowledge management and the role of knowledge management as an embedded management practice. The findings of this study should be useful in explaining practitioners the nature, relevance and value of knowledge management. 相似文献

The prevalence and context of violence against children in their families was surveyed as part of a study on the sexual abuse of children. A random sample of 409 comprehensive school classes with approximately 9,000 15-year-olds was asked to anonymously fill out questionnaires. The majority filled out the questionnaires in the privacy of the school nurse's office, the rest in their classrooms. Of the selected classes, 88.8% participated in the survey, and the response rate of the students in those classes was 96%. Mild violence (slapping, pushing, etc.) was reported by 72% of the respondents, and severe violence (hitting with a fist, kicking, use of weapons) was reported by 8%. Violence was committed by the parents sometime before the children reached age 14. Incidents of violence during the year preceding the survey were reported by 19% and 5%, mild and severe, respectively. Mild violence was committed slightly more often by mothers than fathers. Severe violence was perpetrated more frequently by fathers. Girls reported mild abuse more often than boys. Severe violence was experienced equally often by both sexes. Children living with single mothers reported less-than-average mild violence, but more frequent severe violence. The highest incidence of severe violence was found among youth living in families with a stepfather. Unemployment in a family tended to increase both mild and severe violence. Violence was reported least often by children living in farming families or Swedish speaking families (which make up about 6% of Finnish population). Overall the frequency of violence toward children in Finland is significantly lower than in the U.S. Comparison to Sweden seems to show an identical level of child abuse, although different study methods make comparisons difficult. 相似文献

The aim of this study was to examine the effects of muscle-tendon length on joint moment and power during maximal sprint starts. Nine male sprinters performed maximal sprint starts from the blocks that were adjusted either to 40 degrees or 65 degrees to the horizontal. Ground reaction forces were recorded at 833 Hz using a force platform and kinematic data were recorded at 200 Hz with a film camera. Joint moments and powers were analysed using kinematic and kinetic data. Muscle - tendon lengths of the medial gastrocnemius, soleus, vastus medialis, rectus femoris and biceps femoris were calculated from the set position to the end of the first single leg contact. The results indicated that block velocity (the horizontal velocity of centre of mass at the end of the block phase) was greater (P < 0.01) in the 40 degrees than in the 65 degrees block angle condition (3.39 +/- 0.23 vs. 3.30 +/- 0.21 m . s(-1)). Similarly, the initial lengths of the gastrocnemius and soleus of the front leg in the block at the beginning of force production until half way through the block phase were longer (P < 0.001) in the 40 degrees than in the 65 degrees block angle condition. The initial length and the length in the middle of the block phase were also longer in the 40 degrees than in the 65 degrees block angle condition both for both the gastrocnemius (P < 0.01) and soleus (P < 0.01-0.05) of the rear leg. In contrast, the initial lengths of the rectus femoris and vastus medialis of the front leg were longer (P < 0.05) in the 65 degrees than in the 40 degrees block angle condition. All differences gradually disappeared during the later block phase. The peak ankle joint moment (P < 0.01) and power (P < 0.05) during the block phase were greater in the 40 degrees than in the 65 degrees block angle condition for the rear leg. The peak ankle joint moment during the block phase was greater (P < 0.05) in the 40 degrees block angle for the front leg, whereas the peak knee joint moment of the rear leg was greater (P < 0.01) in the 65 degrees block angle condition. The results suggest that the longer initial muscle-tendon lengths of the gastrocnemius and soleus in the block phase at the beginning of force production contribute to the greater peak ankle joint moment and power and consequently the greater block velocity during the sprint start. 相似文献

To promote students’ value-based agency, responsible science and sustainability, science education must address how students think about their personal and collective futures. However, research has shown that young people find it difficult to fully relate to the future and its possibilities, and few studies have focused on the potential of science education to foster futures thinking and agency. We report on a project that further explored this potential by developing future-oriented science courses drawing on the field of futures studies. Phenomenographic analysis was used on interview data to see what changes upper-secondary school students saw in their futures perceptions and agentic orientations after attending a course which adapted futures thinking skills in the context of quantum computing and technological approaches to global problems. The results show students perceiving the future and technological development as more positive but also more unpredictable, seeing their possibilities for agency as clearer and more promising (especially by identifying with their peers or aspired career paths), and feeling a deeper connection to the otherwise vague idea of futures. Students also felt they had learned to question deterministic thinking and to think more creatively about their own lives as well as technological and non-technological solutions to global problems. Both quantum physics and futures thinking opened new perspectives on uncertainty and probabilistic thinking. Our results provide further validation for a future-oriented approach to science education, and highlight essential synergies between futures thinking skills, agency, and authentic socio-scientific issues in developing science education for the current age.

ABSTRACTIn this paper, we explore the part mobile phone use plays in the capitalist assemblages present in school classrooms. Capitalism is approached through the continuous movement of de- and re-territorialisation. The empirical grounding is a wide study on mobile phone use conducted at an upper secondary school in Finland. The focus of this paper is one psychology lesson on puberty and the ways in which territories such as puberty are challenged in the school life of young people through their mobile phone use in class. Analysing a student’s Tumblr photo stream, we show how smartphones challenge the existing territorialities in a classroom. We locate three central deterritorialising movements: in relation to the physical space of the classroom; to the affective space of the classroom; and to the notion of body in puberty. We conclude that mobile phone use matters to students intimately and channels flows of capitalism at school. 相似文献
