Career ladder impact on student achievement and teacher characteristics.

摘要

Current research on Career Ladder Teacher Incentive Plans indicates a need to go beyond the usual description of legislation, career ladder plans, teacher evaluation procedures and "intent" of the policymakers. This study uses a multivariate analysis of variance (MANOVA) to examine the interaction among teacher participation on a career ladder project, student achievement and teacher characteristics. Student achievement test scores over a two year period were analyzed. One group of students had teachers who participated for two years on a career ladder and the other group had teachers who did not participate the two years. One hundred forty teachers and two thousand two hundred sixty-three students in grades 3, 4 and 5 were analyzed in order to identify differences in test scores due to teacher participation. Contrasts were drawn between teachers as participants and non-participants on the career ladder, years of experience and education and their influence on how students scored on a State Mandated Norm Referenced Test, the Iowa Test of Basic Skills. Comparisons of the two groups in the study lead to some fairly consistent results. Even though there were no variables that impacted the achievement scores from a statistically significant standpoint, when the factor of "time" was defined in terms of Ladder and non-Ladder participation, the two year group showed statistically different results from the one year group. The results of this study indicate that a Career Ladder Program in the course of one year or two years would not significantly impact student achievement. However, the element of time is an important factor when looking at the potential for career ladder impact on student achievement. This factor should be considered in any quest for immediate versus long term success patterns of such plans.
