沉睡的天使

曾经的＂96黄金一代＂正在慢慢从舞台的中央移向大幕之侧,即使曾经无所不能的科比,本赛季也明显露出了疲态。小奥从来都不是这一代中的顶尖球员,现在伤病又无情地袭扰着他,不轰轰烈烈却绵绵长长。但小奥尼尔这位沉睡的天使,终有一天会回复青春。     

High-Ability Grouping: Benefits for Gifted Students’ Achievement Development Without Costs in Academic Self-Concept

Effects of full-time ability grouping on students’ academic self-concept (ASC) and mathematics achievement were investigated in the first 3 years of secondary school (four waves of measurement; students’ average age at first wave: 10.5 years). Students were primarily from middle and upper class families living in southern Germany. The study sample comprised 148 (60% male) students from 14 gifted classes and 148 (57% male) students from 25 regular classes (matched by propensity score matching). Data analyses involved multilevel and latent growth curve analyses. Findings revealed no evidence for contrast effects of class-average achievement or assimilation effects of class type on students’ ASC. ASC remained stable over time. Students in gifted classes showed higher achievement gains than students in regular classes.     

Motor schema theory after 27 years: reflections and implications for a new theory

The schema theory for discrete motor skill learning (Schmidt, 1975), originally published in 1975, has generated considerable interest and received strong challenges over its lifetime. In this paper, I focus on the findings generated since 1975 that bear on the theory and highlight those that produce difficulties for it and will be motivators for differing theoretical viewpoints in the future. At the same time, I examine other lines of evidence that seem to bolster the original lines of thinking. Finally, I provide some suggestions for a much needed new generation of motor learning theory, pointing out particular features from the schema theory that could be included and suggesting gaps and omissions that will need additional data and theorizing in future attempts.
