Abstract In this study, we investigated the differential effect of regional economic prosperity on mean student cognitive achievement by analysing data from a “natural experiment” in Palestine. Its main regions, Gaza and the West Bank, inhabited by a population sharing history, culture and gene pool, were only recently separated, yet distinctively affected by geopolitical events. The “experimental group”, living in Gaza, suffered from an enduring politico-economic crisis treatment, while the “control group”, inhabitants of the West Bank, was exposed to a much shorter and milder crisis. As a manipulation check, we used economic data reported by Etkes and Zimring (2015), who uncovered a severe and lasting decrease in household welfare and labour productivity in Gaza. As dependent variables, we used achievement scores of TIMSS maths and science students, which displayed only negligible pro-West Bank, pre-crisis differences (maths: Cohen's d = −0.04; t = −0.56; science: d = 0.11; t = 1.48). This margin grew during the crisis (maths: d = 0.17; t = 2.65; science: d = 0.26; t = 4.25) and even more so in the post-crisis phase (maths: d = 0.38; t = 5.09; science: d = 0.46; t = 6.76). Our results corroborate correlational evidence for economic effects on cognitive achievement (cf. Hunt, 2012). Relying on a natural experiment, we were able to rule out genetic effects and highlight the impact of the environment on students' academic achievements. Limitations of the design and implications for further studies on regional differences in cognitive achievement are discussed.

经济危机对学生认知成就的不利影响——来自巴勒斯坦的自然实验

摘要 在这项研究中,我们通过分析来自巴勒斯坦“自然实验”的数据,研究了区域经济繁荣对学生平均认知成就的不同影响。其主要地区加沙和西岸居住着共享历史、文化和基因库的人口,最近才分开,但明显受到地缘政治事件的影响。居住在加沙的“实验组”遭受了持久的政治经济危机待遇,而西岸居民的“对照组”则遭受了更短、更温和的危机。作为操纵检查,我们使用了 Etkes 和 Zimring (2015) 报告的经济数据,他们发现加沙的家庭福利和劳动生产率严重而持久地下降。作为因变量,我们使用了 TIMSS 数学和科学学生的成绩分数,这些分数仅显示出可忽略不计的亲西岸和危机前的差异(数学:科恩的 d = -0.04;t = -0.56;科学:d = 0.11;t = 1.48)。这一利润率在危机期间有所增长(数学:d = 0.17;t = 2.65;科学:d = 0.26;t = 4.25),在危机后阶段更是如此(数学:d = 0.38;t = 5.09;科学: d = 0.46;t = 6.76)。我们的结果证实了经济对认知成就的影响的相关证据(参见 Hunt,2012)。依靠自然实验,我们能够排除遗传影响并突出环境对学生学业成绩的影响。讨论了设计的局限性和对认知成​​就区域差异进一步研究的影响。危机前的差异(数学:科恩的 d = -0.04;t = -0.56;科学:d = 0.11;t = 1.48)。这一利润率在危机期间有所增长(数学:d = 0.17;t = 2.65;科学:d = 0.26;t = 4.25),在危机后阶段更是如此(数学:d = 0.38;t = 5.09;科学: d = 0.46;t = 6.76)。我们的结果证实了经济对认知成就的影响的相关证据(参见 Hunt,2012)。依靠自然实验,我们能够排除遗传影响并突出环境对学生学业成绩的影响。讨论了设计的局限性和对认知成​​就区域差异进一步研究的影响。危机前的差异(数学:科恩的 d = -0.04;t = -0.56;科学:d = 0.11;t = 1.48)。这一利润率在危机期间有所增长(数学:d = 0.17;t = 2.65;科学:d = 0.26;t = 4.25),在危机后阶段更是如此(数学:d = 0.38;t = 5.09;科学: d = 0.46;t = 6.76)。我们的结果证实了经济对认知成就的影响的相关证据(参见 Hunt,2012)。依靠自然实验,我们能够排除遗传影响并突出环境对学生学业成绩的影响。讨论了设计的局限性和对认知成​​就区域差异进一步研究的影响。25),在危机后阶段更是如此(数学:d = 0.38;t = 5.09;科学:d = 0.46;t = 6.76)。我们的结果证实了经济对认知成就的影响的相关证据(参见 Hunt,2012)。依靠自然实验,我们能够排除遗传影响并突出环境对学生学业成绩的影响。讨论了设计的局限性和对认知成​​就区域差异进一步研究的影响。25),在危机后阶段更是如此(数学:d = 0.38;t = 5.09;科学:d = 0.46;t = 6.76)。我们的结果证实了经济对认知成就的影响的相关证据(参见 Hunt,2012)。依靠自然实验,我们能够排除遗传影响并突出环境对学生学业成绩的影响。讨论了设计的局限性和对认知成​​就区域差异进一步研究的影响。学术成果。讨论了设计的局限性和对认知成​​就区域差异进一步研究的影响。学术成果。讨论了设计的局限性和对认知成​​就区域差异进一步研究的影响。
