Using TIMSS Data to Investigate Rural- Urban Differences of Taiwanese Eighth Graders’ Mathematics Achievement from 2003 to 2011
This study explored Taiwanese eighth graders’ mathematics achievement differences between town and urban areas and between rural and urban areas based on the data of TIMSS 2003 to 2011. Using recentered influence function regressions, the study has found that there were significant widening differences between the achievement of town students’ and that of urban students from 2007 to 2011 due to the improvement of urban students’ achievement. In 2011, the achievement of low ranking urban students with low home-education-resources have improved and the left tail of their distribution was shortened; the achievement of middle and high ranking urban students with high home-education-resources have improved and their distribution was stretched to the right. In 2011, comparing with urban students, town and rural students fall behind academically for 0.45 and 0.57 standard deviation on average, half of which was caused by the town-urban and rural-urban differences of home-education- resources. Using the intermediate international benchmark of TIMSS as the basic achievement line, in 2011, the lagging student ratios of urban, town, and rural were 5%, 13%, and 16%. For the students with insufficient home-education-resources, the town-urban and rural-urban differences in the lagging student ratio were worse. For urban, town, and rural area, the lagging students’ achievement gaps from the basic achievement line had no significant differences.
