The effect of a laboratory-based, in-context, constructivist teaching approach on preservice teachers' science knowledge and teaching efficacy.

The effect of a laboratory-based, in-context, constructivist teaching approach on preservice teachers' science knowledge and teaching efficacy.

Description: This study began with a concern about elementary teachers, as a whole, avoiding the teaching of science in the elementary classroom. The three main factors noted as reasons for this avoidance were: (1) minimum science requirements to reach certification, leading to a lack of preparedness; (2) lack of exposure to science in elementary school; and (3) general dislike for and understanding of science leading to a low self-efficacy in science teaching. The goal of the Environmental Science Lab for Elementary Educators (ESLEE) was to conduct an intervention. The intervention was lab-based and utilized in-context, constructivist approaches to positively influence participants' abilities to retain science content knowledge and to affect their belief in themselves as teachers. This intervention was created to respond to all three of the main avoidance factors noted above. The research utilized a quasi-experimental, pretest-posttest control group design. Two pretests and two posttests (science teaching efficacy and content knowledge) were given to all 1,100 environmental science lab students at the participating institution over two long semesters. Three experimental/control groups were formed from this population. The Experimental Group was comprised of 46 students who participated in the ESLEE Intervention. Control Group 1 was comprised of 232 self-described preservice educators ...
