The use of unsafe water as a source for drinking, cooking, and bathing can lead to serious health complications. Point of Use (POU) water treatment technologies can play an important role in making safe and clean drinking water available to communities. One low-cost, low-technology POU system is the biosand filter (BSF). BSFs offer an effective…

Students often enter chemistry laboratory courses with a well-documented disconnect between their experiences outside the classroom and the procedures, concepts, and techniques that occur in our courses. Strong base, weak acid titration experiments are present in general chemistry laboratories but also relate to foods our students are familiar…

Genetics is known to be one of the most challenging subjects in biology education because of its abstract concepts and processes. Therefore, hands-on experiments in authentic learning environments are supposed to increase comprehensibility and provide otherwise unavailable experiences to students. We applied a hands-on module in an out-of-school…

This project involves students in a course-based undergraduate research experience (CURE) as part of the traditional introductory biology laboratory course. Recently, research has shown that student engagement in authentic research has significant positive impacts on students, such as development of science literacy and reasoning skills. Being…

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…

We investigated the impact of inquiry-based learning on the situational interest (SI) of senior high school students in a molecular biology class. In part I of our study we designed an inquiry-based learning class as an experimental workshop in an out-of-school student lab and compared it with the participants' regular biology class. The workshop…
