In inquiry-based science education, there have been gradual shifts in research interests: the nature of scientific method, the debates on the effects of inquiry learning, and, recently, inquiry teaching. However, many in-service programs for inquiry teaching have reported inconsistent results due to the static view of classroom inquiries and due to the partial perspective between individual and collaborative reflections. Thus, by means of a theoretical progress model of collaborative reflection, this qualitative research aims to investigate reflections of four participant teachers before and during a half-year in-service teacher program. The model captures the following four interactions for each individual teacher and among the teacher cohort: belief to practice, practice to belief, stimulation, and reinforcement. The audio–video data and their quantification allowed identification of the teachers’ consistent prior beliefs and practices as a multiplicity of inquiry teaching and their interwoven progress during the program. The findings are further discussed in terms of the implicit development and the richer repertoire. 相似文献

This mixed-methods study investigated the changes in Chinese students’ motivation to learn English from elementary to high school and explored the reasons for these changes at different school levels. A motivational questionnaire was designed and administered to 3,777 elementary, junior high, and high school students, and follow-up interviews were then conducted with nine students in order to investigate their perceptions of their motivations. Seven subcomponents of motivation were identified. The statistical results revealed that junior high school students had the highest learning motivation, followed by those in elementary school and those in high school. The interview data indicated that parents’ positive influence on students’ English learning motivation was greater for junior high school students compared to elementary and high school students. Furthermore, the pressure of the college entrance examination had a negative influence on high school students’ motivation to learn English. Based on the findings of this study, suggestions for further research are provided. 相似文献

The purpose of this study was to explore latent class based on growth rates in number sense ability by using latent growth class modeling (LGCM). LGCM is one of the noteworthy methods for identifying growth patterns of the progress monitoring within the response to intervention framework in that it enables us to analyze latent sub-groups based not on an arbitrary cut-point but on each group’s growth pattern. Progress monitoring data for number sense were administered in four times for age of 4(n = 58), 5(n = 95), and 6(n = 58) children, by the measure named basic academic skill assessment: number sense developed to assess students’ number sense and includes Number identification, Missing number, Quantity discrimination and estimation. To perform LGCM analysis, M plus 5.0 was used, and Bayesian information criteria and entropy values were used as criteria to determine the number of sub-groups. Results showed that there were 2, 4, and 4 sub-groups according to each age group based on the growth patterns. Each group’s growth patterns were classified differently based on their initial performance and growth level. Advantages and limitations of using LGCM method to analyze latent groups’ growth patterns for screening and identifying children at risk were discussed. 相似文献

Previous studies have provided mixed results for the effects of social constraints on career maturity. However, there has been growing interest in these effects from the time perspective. Few studies have examined the effects of social constraints on the time perspective which in turn influences career maturity. This study examines the mediating effect of the present-oriented perspective on the relation between social constraints and career maturity. The results based on a panel survey of middle and high school students in Korea indicate that the time perspective mediates the relation between socioeconomic status (SES) and career maturity regardless of the level of academic achievement. The results have important implications for intervention programs for low-SES children’s time perspective, which may mitigate the transmission of social constraints, thereby raising the bar for their academic and career goals: Such programs may be useful for enhancing low-SES children’s career readiness. 相似文献

With its remarkable growth, the cable TV industry has witnessed increasing business integration continuously. This study categorizes technology-based operators into 3 groups on the basis of business integration—vertically integrated, horizontally integrated, and isolated system operators-and estimates the efficiency of each group. In addition, metafrontier analysis is employed to compare the efficiencies of the groups. The results suggest that vertically and horizontally integrated system operators can improve technical efficiency by accomplishing economies of scope and scale, respectively. 相似文献

This article investigates whether acquiring telecommunications firms managed their earnings by means of discretionary accruals prior to the announcement of stock-for-stock takeovers in the U.S. telecommunications industry during the period of 1990 to 2006. The results show that acquiring telecommunications firms manage earnings upward prior to stock-for-stock takeovers. In addition, this article finds that there is a negative short-term wealth effect over the days surrounding stock-for-stock takeover announcements, and there is an inverse relation between earnings management and short-term wealth. 相似文献

Focusing on alcohol-involved social gatherings (i.e. drinking parties), the current study examined the reasons for and outcomes of joining drinking parties and evaluations of them. In studies 1 and 2, Korean workers (n=87) employed in the civil engineering industry and undergraduates (n=103) from various engineering majors provided desirable and undesirable reasons for and outcomes of joining drinking parties with their colleagues (coworkers for working adults and school friends for undergraduates). In studies 3 and 4, Korean workers (n=102) and undergraduates (n=89) evaluated each of the outcomes as either social, personal, or both. In study 5, Korean workers (n=108) and undergraduates (n=111) evaluated how good or bad each outcome type would be. Findings showed that among the five types of the drinking party participation outcomes, the conversation category and the work-/school-life category were the ones for which working adults and undergraduates had similar evaluations. For the group, the hierarchical relationship, and the drinking categories, however, working adults and undergraduates had different evaluations. These and other findings are presented in detail, and the implications thereof are discussed. 相似文献

Framing Analysis of a Conflict: How Newspapers in Five Asian Countries Covered the Iraq War 总被引:1,自引:0,他引:1
This five-country study examined the extent to which the news coverage of the Iraq war by newspapers from India, Sri Lanka, Indonesia, and the Philippines and by one news agency from Pakistan is framed according to the principles of war/peace journalism outlined by Johan Galtung. The findings, based on a content analysis of 442 stories from eight newspapers, suggest a slight peace journalism framing. Two important factors shaping the news framing of the conflict and support for the war and for the protagonists in the war (Americans/British vs. Iraqis) are religion and sourcing. Newspapers from the non-Muslim countries, except the Philippines, have a stronger war journalism framing, and are more supportive of the war and of the Americans/British than the newspapers from the Muslim countries, which are more supportive of the Iraqis. Stories produced by foreign wire services have a stronger war journalism framing, and show more support for the war and for the Americans/British than stories written by the newspapers’ own correspondents. 相似文献

This study analyzes how a female candidate was presented in the news media and on her campaign website, in order to compare the politics of gender representation in news coverage and campaign communication. Content analysis of news coverage of a Korean female candidate and the candidate's website shows that the female candidate was differently portrayed in the two media in presentations of personal trait frames, the linkage between issues and personal traits, and other gender-related characteristics, although the quantity of issue frames did not differ significantly. The findings suggest that although the news coverage still tends to reinforce gender stereotypes regarding a female candidate, the candidate used or articulated gender identities in her campaign website to oppose framing stereotypes in the traditional news media. 相似文献
