贫困和弱势群体的教育一直是发达国家和发展中国家教育系统面临的一个长期挑战。本文利用两项随机对照试验的数据,涉及中国青海省贫困农村少数民族学校的两组三年级学生,探讨了计算机辅助学习(CAL)对学生学业和非学业成绩的影响,以及CAL计划和现有课堂资源之间的相互作用如何影响计划的有效性。结果表明,CAL可以对学生的学术和非学术成果产生显着的有益影响。然而,当该计划的范围扩大到包括第二个科目(在这种情况下,数学-这是在普通话科目的基础上增加的,这是该计划第一阶段的重点)时,一些学校不得不使用正常的上课时间进行CAL课程。因此,第二阶段方案与第一阶段相比没有产生任何(统计上的)重大改进。
ABSTRACT The education of poor and disadvantaged populations has been a long-standing challenge for education systems in both developed and developing countries. Drawing on data from two randomised controlled trials involving two cohorts of grade 3 students in poor rural minority schools in China’s Qinghai province, this paper explores the effects of computer-assisted learning (CAL) on student academic and non-academic outcomes for underserved student populations, and how interactions between the CAL programme and existing classroom resources affect the programme effectiveness. Results show that CAL could have significant beneficial effects on both student academic and non-academic outcomes. However, when the scope of the programme expanded to include a second subject (in this case, math – which was added on top of the Mandarin subject matter that was the focus of the first phase of the programme), some schools had to use regular school hours for CAL sessions. As a result, the phase II programme did not generate any (statistically) significant improvement over the first phase.
