Evaluating the Long Term Effects of Teacher Enhancement

小行星9714189 本研究以一个科学教师提升计画为例，透过多重方法的纵向研究，填补长期提升评估的差距。 这项评估将研究教师增强对现有学生群体的长期影响，以及教师增强对新学生群体的后续影响。 具体而言，该项目将通过比较教师参加和不参加提高项目的学生群体来研究教师提高项目的持续性。 建议进行两项调查：1）跟踪9年级学生到12年级的队列，比较科学成绩; 2）比较9年级学生后续队列的学习环境和科学成绩。 这两项调查将使我们能够确定教师增强项目持续到未来的程度。 拟议的评估将在参加教师提高项目的五所高中进行。 我们将收集各种各样的数据，包括教师的课堂观察，每年两次，与教师和学生的访谈，与校长的访谈，学生的书面问卷调查，并动手和学生的NRC科学标准的成绩书面评估。 本次评估的结果将被用来检查在何种程度上NSF资助的教师增强可以影响教师的表现，并随后影响在科学成果。

9714189 Lawrenz This project proposes to fill the gap in long-term enhancement evaluation by conducting a multiple method, longitudinal study of a science teacher enhancement project. This evaluation will examine both the long term effects of teacher enhancement on an existing cohort of students, and the subsequent effects of teacher enhancement on new cohorts of students. Specifically, the project will examine the persistence of a teacher enhancement project by comparing groups of students whose teachers did and did not participate in the enhancement project. Two investigations are proposed: 1) follow cohorts of 9th grade students into 12th grade to compare science achievement; 2) compare the learning environment and science achievement of subsequent cohorts of 9th grade students. These two investigations will allow us to determine the extent to which the teacher enhancement project persisted into the future. The proposed evaluation will be conducted at five high schools that participated in the teacher enhancement project. We will collect a comprehensive variety of data including classroom observations of teachers twice a year, interviews with teachers and students, interviews with principals, student written questionnaires, and both hands-on and written assessments of students' achievement of the NRC science standards. The results of this evaluation will be used to examine the extent to which NSF funded teacher enhancement can affect teacher performance and subsequently affect outcomes in science.
