Abstract This three-year longitudinal study tracked the reading performance of 68 kindergarten students from low SES backgrounds. These students received instruction with a blended learning program ——Lexia® Core5® Reading—from the start of kindergarten through second grade. During each school year the students made significant gains on a standardized reading test. However, performance on the test declined significantly from the spring of one school year to the fall of the next, indicative of a substantial summer slide. Yet, further comparisons revealed that performance from the fall of one school year to the fall of the next showed significant improvement, pointing to the benefits of school-based instruction to help overcome the summer slide. More than 90% of low performers who started kindergarten scoring below average on the standardized test finished second grade scoring average or better. Benefits of Lexia Core5® Reading to support reading growth in elementary school students from low SES backgrounds are discussed.

三年纵向研究：Lexia®Core5®混合学习计划对低SES幼儿园儿童阅读增值的影响

摘要这项为期三年的纵向研究追踪了68名来自低SES背景的幼儿园学生的阅读表现。从幼儿园开始到二年级，这些学生都接受了混合学习程序Lexia®Core5®Reading的指导。在每个学年中，学生都通过标准化阅读测试取得了显著成绩。但是，从一个学年的春季到下个学年的秋季，该考试的成绩显着下降，这表明夏天的考试成绩相当不错。然而，进一步的比较表明，从一个学年的秋季到下一个学年的秋季的表现显示出显着的提高，指出了以学校为基础的教学有助于克服暑假的好处。超过90％的在幼儿园开始低于标准考试的平均成绩的低表现者完成了二年级或更高的平均成绩。讨论了LexiaCore5®Reading的优势，以支持来自低SES背景的小学生的阅读增长。
