Researchers have reported that participation in agricultural education reinforces STEM concepts, often through project-based learning. The use of projects is common in agricultural education. However, the instructional importance of certain elements of these projects is not well understood. We conducted a quasi-experimental study to examine the…

This article is a qualitative study that explored bilingual/ESL science teachers' reflections about subject matter knowledge (SMK) and instructional practice in the elementary grades. Thirty-three teachers were part of a 5-year professional development program designed to enhance instructional quality and effectiveness to teach English learners.…

The overarching purpose of our study was to compare performances of treatment and control condition students who completed a literacy-infused, inquiry-based science intervention through sixth grade as measured by a big idea assessment tool which we refer to as the Big Ideas in Science Assessment (BISA). First, we determine the concurrent validity…

This study characterizes the impact of an inquiry-based learning (IBL) module versus a traditionally structured laboratory exercise. Laboratory sections were randomized into experimental and control groups. The experimental group was taught using IBL pedagogical techniques and included manipulation of large-scale data-sets, use of multiple…

Demonstrations can be very effective at enhancing student learning and represent a mechanism for embedding laboratory experiences within a classroom setting. A key component to an effective demonstration is active student engagement throughout the entire process, leading to a guided laboratory experience in a lecture setting. Students are involved…
