Since the late 1990s, there has been consensus among educational researchers that argumentation should play a central role in science education. Although there has been extensive relevant research, it is not clear enough how oral argumentation spontaneously occurs in science teaching. This is particularly important with regard to the empirical evidence suggesting the effect of discussion of contradictory views on scientific learning. In order to contribute to the research on argumentation in science teaching, we conducted a study that aims to sketch a panoramic view of the uses of oral argumentation in Chilean middle-school science teaching. A total of 153 videotaped science lessons were observed, involving students aged 10–11 and 12–13. Whole-class argumentative discourse was analysed as a function of thematic episodes and teachers' and students' utterances. Results suggest that argumentative discourse in which contradictory points of view are discussed is scarce but when it occurs it does so predominantly within discourse among students. On the contrary, argumentation aimed at justifying points of view is widely used, even more so when students are older. 相似文献

Few studies have empirically investigated the specific factors in mentoring relationships between undergraduate researchers (mentees) and their mentors in the biological and life sciences that account for mentees’ positive academic and career outcomes. Using archival evaluation data from more than 400 mentees gathered over a multi-year period (2005–2011) from several undergraduate biology research programs at a large, Midwestern research university, we validated existing evaluation measures of the mentored research experience and the mentor–mentee relationship. We used a subset of data from mentees (77% underrepresented racial/ethnic minorities) to test a hypothesized social cognitive career theory model of associations between mentees’ academic outcomes and perceptions of their research mentoring relationships. Results from path analysis indicate that perceived mentor effectiveness indirectly predicted post-baccalaureate outcomes via research self-efficacy beliefs. Findings are discussed with implications for developing new and refining existing tools to measure this impact, programmatic interventions to increase the success of culturally diverse research mentees and future directions for research. 相似文献

The present study examined the outcomes of a newly designed four‐lesson science module on opinion‐forming in the context of genomics in upper secondary education. The lesson plan aims to foster 16‐year‐old students’ opinion‐forming skills in the context of genomics and to test the effect of the use of fiction in the module. The basic hypothesis tested in this study is whether fiction stimulates students to develop opinions with regard to socio‐scientific issues. A quasi‐experimental pre‐test and post‐test design was used, involving two treatment groups and one control group. One of the experimental groups received a science module incorporating movie clips (i.e., the movie group). The other experimental group received the same science module, but only news report clips were used (i.e., the news report group). Prior to and after the module, 266 secondary school students completed a questionnaire to test their opinion‐forming skills. The results demonstrate that the science module had a significant positive effect on students’ opinion‐forming skills and that the movie group improved their skills more compared with the news report group. It may be concluded that the use of fiction—to be more specific, movie clips about genomics extracted from feature films—to introduce a socio‐scientific issue in the classroom stimulates students to develop their opinion‐forming skills. 相似文献

This article questions whether the teacher training standards, (Department for Education and Employment Circular 4/98) have made it more difficult for teacher educators to help student teachers to become critically reflective teachers. It is suggested that, following the introduction of the discourse of the three 'e's', efficiency, economy and effectiveness and the teacher training standards, teacher 'education' has been transformed into teacher 'training' within an ideology of technical rationality. Four classroom-based episodes are introduced to form the contexts through which the teacher education standards are interrogated. It is argued that these standards ignore important issues to do with equality in the classroom and the relationship between education and the state. Ideas are suggested for teaching sessions using the episodes to encourage the development of a critically reflective perspective amongst student teachers. 相似文献

This paper adopts a social constructionist position on assessment, specifically that it can never be free of the social conditions in which it is practiced. As such, we explore two aspects of classroom interactions which contribute to and shape the learning environments in which assessment takes place. By drawing on interviews carried out with 51 teachers and 307 Year 3 (7–8‐year‐old) pupils the paper demonstrates where and how beliefs and attitudes about gender influence what they perceived as ‘good’ or ‘appropriate’ working relationships. It also considers the ways in which teachers utilize perceptions of gender to plan the curriculum and manage their classrooms. Whilst the pupils believed their teachers treated them in a fair and just manner, three quarters of the teachers interviewed believed they did or should respond differently to pupils according to gender. We argue that the emphasis given to boys’ underachievement has contributed to this scenario. 相似文献

The direction that secondary school reform should take has become a contested question in the province of Ontario, Canada, during the 1990s. This case study of one secondary school examines some of the issues surrounding the transition years. Two policies, destreaming and integration, mandatedbythe OntarioMinistryof Education in 1993, and fully implemented by 1995, are examined by means of interview and survey. Administrators, teachers and students commented on the transition from elementary to secondary school. We discuss questions related to destreaming (especially how teachers contend with mixed-ability classes) and integration (with a particular focus on mathematics, science and technology). 相似文献
