Students' Ideas and Attitudes about Air Quality   总被引:1,自引:0,他引:1  
The results of a large scale (N=1001) cross-sectional (Years 6, 8 and 10) study of students' ideas about the composition of unpolluted air, the nature of air pollution, the biological consequences of air pollution, and about acid rain and the Greenhouse Effect are reported. A range of persistent alternative conceptions were identified, in some instances with increasing frequency across grades. Students' attitudes towards education, obligation, legislation or taxation as a way of reducing air pollution were determined; the first two were the most favoured. Increased attention to particular gas and air pollution concepts is recommended; other pedagogical implications are discussed.  相似文献

The purpose of this article is to highlight the important role that gender plays in organizing and affecting the quality of the classroom climate. We review research showing how students’ peer relationships tend to be segregated by gender and discuss the consequences of children spending much of their time almost exclusively with same-gender peers, which perpetuates and exaggerates gender segregation. We suggest that a more beneficial pattern is enhancing students’ exposure to other-gender peers—that is, promoting gender integration. We describe the theories that support the benefits of integrating across social groups. Next, we review methods and results of strategies we have used to promote integration. Finally, we draw attention to the issues about gender integration that require further consideration and argue for more research that can help guide the development of effective strategies that build more inclusive environments, practices, and policies for today’s children and youth.  相似文献

This article considers the ways in which three alternative education sites in Australia support socially just education for their students and how injustice is addressed within these schools. The article begins with recognition of the importance of Nancy Fraser’s work to understandings of social justice. It then goes on to argue that her framework is insufficient for understanding the particularly complex set of injustices that are faced by many highly marginalised young people who have rejected or been rejected by mainstream education systems. We argue here for the need to consider the importance of ‘affective’ and ‘contributive’ aspects of justice in schools. Using interview data from the alternative schools, we highlight issues of affective justice raised by students in relation to their educational journeys, as well as foregrounding teachers’ affective work in schools. We also consider curricular choices and pedagogical practices in respect of matters of contributive justice. Our contention is that the affective and contributive fields are central to the achievement of social justice for the young people attending these sites. Whilst mainstream schools are not the focus of this article, we suggest that the lessons here have salience for all forms of schooling.  相似文献

This article investigates how a structured post-course follow-up reflection activity affects the depth of reflection and facilitates the transfer of learning. The research is reflective, based on the findings from the Action Learning Management Practicum, a 3rd year paper at Massey University, New Zealand. The initial reflections at the end of the course generally went no deeper than students “noticing”, or “making sense” of the experiences. With the benefit of distance and time away from the course, the students' reflection was deep and insightful. The findings suggest that the post-course reflection activity enables participants to “make meaning” from their experiences with the benefit of time and distance from the initial post-course reflection, thus enhancing the transfer of learning. The article argues for an extension and adaptation to Kolb's “Experiential Learning Cycle” model in relation to the time of reflection based on the empirical evidence provided.  相似文献

In a mathematical examination on paper, partial credit is normally awarded for an answer that is not correct, but, nevertheless, contains some of the correct working. Assessment on computer normally marks an incorrect answer wrong and awards no marks. This can lead to discrepancies between marks awarded for the same examination given in the two different media. The current paper presents possible solutions to this problem and the results of experiments designed to test how successful these solutions are in practice. In light of the findings, developments to the assessment engine have been made and some questions redesigned for use in real automated examinations. The results were obtained as part of the Project for Assessments in Scotland using Information Technology (PASS‐IT): a major collaborative programme involving the leading educational agencies in Scotland (see http://www.pass‐it.org.uk for more details). PASS‐IT has demonstrated that the computer can help measure lower order student skill profiles provided the computer assessment package is sophisticated enough. Optional steps are required to mimic partial credit; randomisation of parameters is needed for practice and the avoidance of copying; the ability to capture and mark automatically mathematical expressions and short free text responses; and the delivery in a number of feedback modes are all vital ingredients of an automatic assessment system. PASS‐IT has shown how to ensure that education drives technology and not vice versa. Finally, collaboration has been paramount within PASS‐IT and should continue. No single group has all the keys to unlock the future of computer‐aided assessment. Scotland is well placed to move forward and e‐assess where its students e‐learn in a large range of subjects such as those delivered via the SCHOLAR Programme (see http://scholar.hw.ac.uk ). It should be done too by ensuring that teachers remain central to the learning cycle by supporting the demanding work they do through the supply of suitably filtered data on student performance. Special educational needs can also be addressed more effectively by the use of technology.  相似文献

This article reports on research funded by the Australian Research Council to investigate school responses to gender equity. It addresses the efforts of a disadvantaged school to tackle what they perceived to be gender inequalities, but in the process of constructing a top‐set and bottom‐set/stream class they are developing new forms of old inequalities and new forms of inequalities. This research indicates that despite popular assertions that girls' education has become the priority of schools and education systems, girls are being further disadvantaged through attempts to implement market strategies coupled with gender reform agendas grounded in liberal notions of equity and relying on unsophisticated notions of affirmative action. In addition, this study highlights the extent to which a media‐driven debate about boys' education has influenced the constitution of boys as the ‘new disadvantaged’ with the capacity to determine the nature of gender reform agendas and programmes in schools.  相似文献

It is widely postulated that school context characteristics and sex may influence students' motivational orientations. However, relatively little empirical evidence exists to support this postulate. Hence the present study sought to examine both the individual and interactive effects of school and sex differences on students' motivational goals. Participants were 602 middle school students. The effects of school and sex on three academic and five social goals were examined. Results suggest that school and (to a lesser extent) sex differences, as well as the interaction between the two, significantly influence students' motivational orientations. Results are discussed and interpreted within the framework of motivation psychology.  相似文献

Two experiments investigated the relationship between activity during shock and the magnitude of subsequent impairment of shock-elicited fighting in the rat. Different levels of intra-shock activity were engendered in two ways. In Experiment 1, differing temporal forms of inescapable shock were employed to produce markedly different levels of activity. In Experiment 2, a passive-escape procedure was used to explicitly reinforce nonmovement during shock relative to a yoked, inescapable shock control. Results indicated that relative to the performance of subjects not previously shocked, fighting impairment was produced only by those prior treatments that promoted reduced intrashock activity. Since one of the prior shock treatments involved inescapable shock but the other did not, these findings may be viewed as strong support for the notion that behavior during shock, rather than uncontrollability, is the critical determinant of the observed impairment effects. There was some suggestion in both studies that shock treatments that resulted in sustained or increased intrashock activity tended to produce augmentation of fighting. Both inhibitory and facilitative effects of prior shock exposure are discussed in terms of an interacting response theory of shock treatment effects.  相似文献

Science in English primary schools has been judged a success, yet few pupils make the progress in secondary schools that their performance at the end of primary school suggested. Projects where pupils start science work at the end of the primary school and complete it at the start of secondary school—known as bridging units—have been suggested as one solution. This article reports an evaluation of bridging work in science in the north‐east of England. Pupils' and teachers' views of bridging lessons were collected and data on pupils' performance before and after bridging lessons compared. Claims that pupils find this type of work repetitive and that their teachers would rather teach something else either side of transfer are challenged. Findings highlight areas that are still problematic, including the use made of transferred assessments and progression in pupils' abilities, to comment on relationships between variables and patterns in data. The future for bridging work is discussed.  相似文献
