Baldwin, Nicole – ProQuest LLC, 2022
Laboratory activities are a prevalent and essential part of chemistry learning because of their potential to help students develop problem solving abilities, visualize chemistry concepts learned in lecture, and gain practical skills. However, learning in the laboratory environment is not without its challenges. For example, cookbook-style…

Hongyang Zhang – ProQuest LLC, 2022
This study uses two different approaches to examining student outcomes and understanding in the context of aspects of acid-base chemistry. It introduces the use of evidence centered assessment design as a design framework of a multi-dimensional acid-base titration laboratory and as an analysis tool of student performances in a lab setting and in…

Olivia M. Reynolds – ProQuest LLC, 2022
Active learning is widely recognized as superior to traditional passive, lecture-based techniques for fostering learning in STEM courses. Interactive, hands-on learning where students interact with their peers and physical systems is an effective type of active learning. As the need for scientists and engineers continues to grow, understanding and…

Kerstiens, Geri Anne – ProQuest LLC, 2019
Recently, there have been many calls for an increase in instruction on the nature of science (NOS) in schools (i.e. NRC, 1996; NGSS Lead States, 2013). These calls recognize the importance of this topic at all levels of science education, but there is little guidance in terms of how to address it effectively in curricula. Similarly, there have…
