The purpose of this study was to examine the effectiveness of computer-animated dissection techniques versus the effectiveness of traditional dissection techniques as related to student achievement. The sample used was 104 general biology students from a small, rural high school in Northeast Tennessee. Random selection was used to separate the…

This paper introduces the biology laboratory as a learning project. Biology laboratories provide unique learning opportunities to students as traditional achievement outcome measures, and play an important role in the development of process skills, manual skills, and attitudes. However, there is insufficient data on undergraduate students majoring…
