The study evaluated the relationship among teaching, leadership, teacher certification, student and teacher number related factors, and index of economic, social and cultural status (ESCS), and science literacy from an international comparative perspective. 2015 dataset of the Programme for International Student Assessment for Turkey, Singapore, the United States, Korea, Italy, and Brazil was used. Two-level hierarchical linear models were established for analysis. Results revealed that school ESCS was the best predictor of science literacy across six countries and additionally teacher-related factors came to the forefront of science literacy performance. The study underlined policymakers should focus primarily on policies that increase equity in education. Furthermore, the effectiveness of investments made in factors related to leadership, teacher certification, the number of students and teachers, which contribute very little to science literacy performance, need to be more questioned. Inferences about the findings were discussed in detail, and recommendations for further research were made. 相似文献

This paper illustrates how theory of change coupled with contribution analysis assisted in delineating the role each aspect of a teacher professional development program contributed to the expected outcomes. Using a mixed methods evaluation based upon the theory of change, data was gathered on 12 teacher leaders over three years. Findings indicated that not only did the teachers continue to develop as leaders over the three year project but also that the interventions designed to provide professional development to the teachers did indeed contribute to the attainment of project outcomes. By combining stakeholders’ theory of change with contribution analysis, evaluators can develop an understanding of program intentions and design an evaluation that enhances the validity of findings. 相似文献

And service supply chain is a new study aspect in supply chain management of services science. This article begins with study on the definition and characters of service supply chain, compares this with traditional supply chain,establishes the structure of its form and puts it into our regional economics to examine its impacts. 相似文献

Entrenched socioeconomic inequalities in achievement have been observed in international assessments for decades, with previous research suggesting that these inequalities may be exacerbated by differentiation in the opportunities provided to various social groups. Much previous research in this field has been US-based or subject to measurement issues. This study investigated socioeconomic inequalities in outcomes and opportunities using four cycles of international assessment data across 78 countries. Further, the paper questions whether inequalities in opportunities are related to inequalities in outcomes. The findings indicate global social inequalities in mathematics and science outcomes, while inequality of opportunity was particularly concentrated in economically advanced countries. Little evidence of the perpetuation of socioeconomic inequality in achievement through differentiated educational provision was found. 相似文献
