摘要

摘要本研究旨在通过借鉴教育有效性的动态模型,确定协同影响高绩效和低绩效学生科学成绩的关键情境因素。该数据集,即2015年国际学生评估计划(PISA),包括来自53个国家/经济体的79963名中学生的科学成绩(49924名6级高成绩者和30039名1a和1b级低成绩者),以及学生和校长对PISA问卷的回答。通过依次应用支持向量机(SVM)和SVM递归特征消除(SVM-RFE),本研究成功地(a)在学校、课堂、,以及协同区分高成就者和低成就者的学生水平,以及(b)通过认识到情境因素的多维性,为支持教育有效性动态模型的有效性提供了证据。

Examining the contextual factors of science effectiveness: a machine learning-based approach
ABSTRACT This research intended to identify key contextual factors that synergistically influence high- and low-performing students’ science outcomes by drawing upon a dynamic model of educational effectiveness. The dataset, the Programme for International Student Assessment (PISA) 2015, consisted of 79,963 science scores for secondary students (49,924 high performers at proficiency Level 6 and 30,039 low performers at proficiency Levels 1a and 1b) from 53 countries/economies along with students’ and school principals’ responses to the PISA questionnaires. By applying a support vector machine (SVM) and SVM-recursive feature elimination (SVM-RFE) sequentially, this study successfully (a) identified 30 key factors of the total 127 contextual factors at the school, classroom, and student levels that synergistically differentiate high and low achievers and (b) provided evidence to support the validity of the dynamic model of educational effectiveness by recognizing the multidimensionality of the contextual factors.

期刊介绍: School Effectiveness and School Improvement presents information on educational effectiveness, practice and policy-making across primary, secondary and higher education. The Editors believe that the educational progress of all students, regardless of family background and economic status, is the key indicator of effectiveness and improvement in schools. The journal strives to explore this idea with manuscripts that cover a range of subjects within the area of educational effectiveness at the classroom, school or system level, including, but not limited to: •Effective pedagogy •Classroom climate •School ethos and leadership •School improvement and reform programmes •Systemwide policy and reform
