The scientific competencies advocated by the Programme for International Student Assessment (PISA) focus on the abilities needed in students' adult lives. This study investigated how such scientific competencies could be improved by using online argumentation. One hundred and thirty-eight 8th grade high school students took part in the study, with 69 in the experimental group and 69 in the control group. A quasi-experimental design was adopted and qualitative and quantitative analyses were used. An online argumentation system served as an aid for argumentation instruction and activities among experimental group students during the experiment. The results showed that using online argumentation could improve the students' scores for the PISA scientific competencies. The experimental group students outperformed their counterparts in terms of overall mean scores for the scientific competencies. On the one hand, the individual competencies of ‘using scientific evidence’ and ‘identifying scientific issues’ of the experimental group were higher than those of the control group. On the other hand, the experimental group students did not outperform their counterparts in terms of competency in ‘explaining phenomena scientifically’. Using an online environment to complement argumentation instruction and organizing argumentation activities focused on related topics may be a potential direction to consider for improving students’ PISA scientific competencies. 相似文献

There is a growing interest in addressing moral aspects in the research and education of socio‐scientific issues. This paper investigates students' interpretations of climate change from a moral perspective. The students were 14 years old, studying at Green Schools in the Beijing area, China. The study was based on semi‐structured group interviews and the data were analysed from an intentional perspective, which means that both cognitive and situational aspects were taken into consideration in the analysis. Previous research has revealed a close relation between morality and socio‐scientific issues and also advocated the need for addressing ethical aspects in science education. However, empirical studies exploring the question of what students' moral reasoning might look like at the individual level have not yet generated enough attention. In this study this is the core focus of interest. The findings show that the students conceptualise the solutions to mitigating climate change in relation to two different stances. That is, they contextualise the problems and solutions by addressing the individual, where the individual is either ‘myself’ or ‘someone else’. The different notions of the individual become crucial as the students' views and considerations for the environment, as well as society, change according to the different contexts. From a moral point of view, the students seem quite unaware of their varying consideration for others, the environment and society. The paper ends with a discussion of implications for practice and research. 相似文献

Multiple Aims in the Development of a Major Reform of the National Curriculum for Science in England
In the context of a major reform of the school science curriculum for 14–16‐year‐olds in England, we examine the aims ascribed to the reform, the stakeholders involved, and the roles of differing values and authority in its development. This reform includes an emphasis on socioscientific issues and the nature of science; curriculum trends of international relevance. Our analysis identifies largely ‘instrumental’ aims, with little emphasis on ‘intrinsic’ aims and associated values. We identify five broad categories of stakeholders focusing on different aims with, for example, a social, individual, political, or economic emphasis. We suggest that curriculum development projects reflecting largely social and individual aims were appropriated by other stakeholders to serve political and economic aims. We argue that a curriculum reform body representing all stakeholder interests is needed to ensure that multiple aims are considered throughout the curriculum reform process. Within such a body, the differentiated character of the science teaching community would need to be represented. 相似文献

This research looked into the effect of how cognitive development toward imagery is formed through visual perception by means of a quantitative questionnaire. The main variable was the difference between the learning backgrounds of the interviewees. A two-way ANOVA mixed design was the statistical method used for the analysis of the 2 × 4 (2 by 4) study design. The analysis on the main effect was conducted, and a significant difference was also shown in the result. First, the two variables of student learning background and imagery cognitive development interact with one another. Second, there is a significant difference in students’ learning backgrounds. The cognitive level between the two was visibly apparent. Last, the four aspects that made up the visual perception all showed significant difference. Therefore, cognitive development will be affected by lifestyle, personal preferences, interests, and biological conditions which will have different levels of influence on visual perception. 相似文献

Many students enroll in video production courses in high school as part of a vocational, career, or technical program. While there has been an explosion of scholarly work in digital literacy in informal settings, less is known about how digital and media literacy competencies are developed through school-based video production courses. This study explores the relationship between civic engagement and the various multimedia instructional practices used in a high school video production course with a single-school convenience sample and an ethnically diverse population of students. Findings reveal that the best predictors of the intent to participate in civic engagement are having positive attitudes about news, current events, reporting, and journalism. Media literacy attitudes and a range of in-classroom learning experiences with video production are also associated with civic engagement. 相似文献

This study examined whether gaining access to a new digital device enhanced the digital media literacy of young adults and what factors determine such change. Thirty-five young adults were given a mobile tablet device and observed for one year. Participants engaged in an online community, responding regularly to online surveys and discussion forums. Digital media literacy, using multidimensional scales, was measured at the beginning and end of the study. Usage was measured every month to track changes over time. When measured with multiple dimensional scales, the participants’ digital media literacy levels increased over time. Those who used the tablet device for information access and social activities increased their digital media literacy in some dimensions. However, an increase in digital media literacy was not directly related to the time spent on the tablet. 相似文献

In recent years, a discourse is emerging in education that emphasises the study of the impact of in-service teacher education on student outcomes (more often than not student outcomes are seen in the form of test scores of academic achievement). Implicit in this discourse is the view that the impact of in-service teacher education is directly observable on students' outcomes, suggesting that the variables in a school or classroom are connected in some kind of a causal link. However, it is problematic to view variables in a social setting such as a school or a classroom as being in causal relationships because social settings are complex so that it is not possible to control the variables or the outcomes. Hence, one cannot convincingly study the outcomes without also studying the process and its complexity. In this article, I describe an action research study undertaken to study the impact in the classroom, of new teaching strategies introduced as part of an in-service teacher education programme in Karachi, Pakistan. By describing this study I mean to suggest that action research is an appropriate methodology to study the impact of in-service teacher education. 相似文献
