“…We searched the EBSCOhost, Directory of Open Access Journals, Google Scholar, and Elsevier databases for key issues and design elements using the following keywords: STEM, science, technology, engineering, mathematics, online, e-learning, science education, distance education, online course activities, universal design for learning, UDL, student feedback, student satisfaction, and student engagement. While limited research was found on effective design elements specific for online STEM courses, ample research has been conducted on effective online course designs in general (Martin, Ahlgrim-Delzell, & Budhrani, 2017;Ralston-Berg, Buckenmeyer, Barczyk, & Hixon, 2015). This search revealed Bayraktar's (2001) meta-analysis which found that computer-assisted instruction increased student performance in science education as well as Schoenfeld-Tacher, McConnell, and Graham's (2001) study in which students in an online section of an upper level science course demonstrated a higher proportion of high-level interactions and outperformed their peers in the corresponding on-campus section.…”
