Environmental degradation is a general problem but it is often more serious in developing nations where levels of awareness are lower than in industrialized countries. There is, therefore, a need particularly in developing countries to increase pro-environmental attitudes and behaviors. In this paper, we report the results of a quasi-experimental study designed to change environmental attitudes and environmental behaviors among 263 science pre-service teachers. The treatment consisted in the form of a green chemistry curriculum. We found statistically reliable changes in environmental attitudes, as measured by the New Ecological Paradigm, and in eight self-reported environmental behaviors. The Bayesian t-test suggests that the evidence for the changes to have been the result of the green chemistry curriculum is decisive. We conclude that the green chemistry curriculum constitutes a suitable context: (a) for supporting pre-service teachers in their development of pro-environmental attitudes and (b) for changing the levels of self-reported pro-environmental actions. 相似文献

The global environmental crisis intensifies particularly in developing nations. Environmental educators have begun to understand that changing the environmental impact requires not only changes in pro-environmental knowledge and attitudes but also in associated, self-determined motivation. This study was designed to test the hypothesis that a green chemistry curriculum changes Malaysian pre-service teachers?? environmental motivation. Two comparable groups of pre-service teachers participated in this study. The students in the experimental group (N?=?140) did green chemistry experiments whereas the control group (N?=?123) did equivalent experiments in a traditional manner. Posttest results indicate that there is significant difference between both the groups for intrinsic motivation, integration, identification, and introjections scales and no differences for external regulation and amotivation scales. The qualitative analysis of interview data suggests that the changes are predominantly due to the personal satisfaction that participants derived from engaging in pro-environmental behavior. 相似文献

A socioscientific issues integrated instruction was used in the study to resolve college students attitude towards sexually-themed science content. Some 200 college students participated in the study as experimental and control groups. The former consisting of 98 students from one college was taught the content using the socioscientific issues integrated instruction. The later with 102 students from another college was taught the same content using a traditionally teacher dominated lectures. Both groups were taught over a period of eight weeks. Qualitative and quantitative data were obtained before and after the intervention. The quantitative data were analysed using analysis of covariance. The results revealed that there was a significant difference between the experimental and the control groups (F (1, 247) = 426.97, p = .00, partial eta squared = 0.64) where the experimental group showed a significant change in attitude towards the content studied. The qualitative data obtained some experimental group students showed a change in attitude the second interview. It was concluded that the use of the approach has significantly made the college students feel comfortable and confident to learn and teach the content. 相似文献

This research investigates the effects of socioscientific instruction on pre-service teachers’ sense of efficacy in the teaching and learning of controversial family health issues. For this purpose, a total of 251 students from two teacher training colleges participated in the study and were randomly assigned as experimental and control groups. The experimental group was taught the contents of the controversial family health issues using socioscientific instruction approach and the control group was taught the same content using a more traditional approach. Quantitative data were obtained from both groups after responding to the ‘Teacher sense of Efficacy Scale’ as instrument used for data collection before and after the treatments. Analysis of covariance was used in data analysis of which the pre-treatment scores were used as covariates. Qualitative interviews were conducted with ten participants randomly selected from the experimental group before and after the treatment to deepen and elaborate the quantitative data. The quantitative and qualitative findings indicate that the integration of the socioscientific instruction have significantly affected the pre-service teachers’ sense of efficacy in favour of the experimental group that shows a more stronger sense of efficacy. It was concluded that the socioscientific instruction is significantly effective in changing the pre-service teachers’ weaker sense of efficacy to a stronger one in the controversial family health issues.

Every day, climate change due to greenhouse emissions, pollution and other environmental degradation appears to make the news. Rather than doing something about the environment, namely in the developing countries where populations frequently are less educated about the long-term impact of human actions, they tend to disregard these problems. There is therefore a need particularly in developing countries to increase the potential for understanding and acting in sustainable, environmentally friendly ways. In this paper, we report quantitative and qualitative results of shifts in environmental value orientations among 110 Malaysian pre-service chemistry teachers during their enrolment in a green chemistry course. We find that the pre-service teachers?? environmental value orientations become more ecocentric and less homocentric and egocentric. Ecocentrism and ecocentric values support the development of behaviours that will assist them and the students they teach in leading environmentally sustainable lifestyles. We conclude that our green chemistry course constitutes (a) a suitable context for supporting pre-service teachers in their development of ecocentric values and (b) an effort to educate the pre-service teachers in leading sustainable lifestyles. 相似文献

Existing studies report on secondary school students’ misconceptions related to climate change; they also report on the methods of teaching as reinforcing misconceptions. This quasi-experimental study was designed to test the null hypothesis that a curriculum based on constructivist principles does not lead to greater understanding and fewer misconceptions on acid rain, global warming, greenhouse effect, and ozone layer depletion than the traditional Malaysian curriculum. For this purpose, two classes from two different schools were randomly assigned to experimental (N?=?35) and control condition (N?=?38). Following the intervention, an ANCOVA with pre-test as the covariate showed statistically significant differences in understanding for all four topics; additional interviews with randomly selected students from experimental and control group further underscore the findings. Implications are discussed. 相似文献

Recent studies emphasize the importance of learning science while considering multiple perspectives on environment, society, economy, and technology, which allows learners to relate what they do in the classroom to the world beyond. In this study, 68 12-year-old primary students from 1 Malaysian school were followed while they engaged in a science curriculum centered around 8 environment-related socio-scientific issues during a unit on the interaction among living things. The analysis shows that the informal reasoning skills of the students improved significantly. Progressive implementation of SSI activities encouraged students to use evidence-based decision-making, improving reasoning modes, and advancing reasoning levels. 相似文献
