  Effects of classroom evaluation strategies on student achievement and attitudes

  摘要：

  This study investigated the effects of teacher evaluation and the combination of teacher evaluation and student self-evaluation on student performance and attitudes. Participants in the study were 189 Latvian high school students and their six teachers.The six teachers were assigned to one of three treatment conditions: (a) no evaluation, (b) teacher evaluation, and (c) self-evaluation plus teacher evaluation. All groups completed a 12-lesson instructional program on how to conduct experiments and produce research reports. Students in the teacher-evaluation group received teacher evaluation on their initial research reports. Students in the self-plus-teacher evaluation group self-evaluated their reports and received teacher evaluation on them. The no-evaluation group received no formal evaluation instructions.Students in the teacher-evaluation and the self-plus-teacher evaluation groups received significantly higher ratings on their final projects than those in the no-evaluation group. However, the no-evaluation group had more favorable attitudes toward the program than the other two groups, while the self-plus-teacher evaluation group was significantly more confident of their ability to independently conduct future research experiments.
