Research on online education has predominantly focused on issues related to student attraction, attrition, retention, and motivation, among others. Little attention has been paid to online instructors and yet, the quality of online education requires educators who understand the expectations of online instruction. Using an online survey, this study examined the expectations and challenges for online instructors and the suggestions for improving online instruction. Based on the data collected from seventeen faculty who teach online courses at four mid-western universities in the US, facilitation, instructor presence, and technical support stood out prominently among the expectations. The major challenges for online instructors were: large class sizes, academic dishonesty, lack of connection with students, too many emails, and lack of student self-discipline. The study recommends viable professional development for online instructors as a pre-requisite to teaching online courses.
Remote physics laboratory activities are common tools of use in physics in traditional, online, and distance education to enhance student learning. Although these offerings necessitated by technological advances, spur innovation and improvement in undergraduate physics education, their use as stand-alone substitutes for instructor-guided physical laboratory experiments remain the center of debate and research. This paper discusses the effectiveness of the current pedagogic issues in the delivery and learning of four different types of remote introductory undergraduate physics laboratory activities, the breakthroughs, and the areas that require further investigations. The instructional issues include experiment preparation and design, student engagement, guidance, and safety. This review noted the positive impacts of stand-alone remote physics lab activities on mostly undergraduate non-physics majors, partly due to the limited number of institutions currently conferring complete online/distance physics degrees worldwide. We recommend further studies on the effect on physics students who end up in experimental physics-related careers.
Student retention and completion rates are challenging issues in higher education. In the academic domain, pressure exists for every institution to come up with strategies that support student success from enrollment through graduation without compromising academic or accreditation standards. This paper presents the findings from a review of student retention models dating back to over eight decades to identify the key factors for retention. Specific recommendations for adaptive and sustainable retention agenda are made. Critical implications of this review directly impact institutional policy makers, researchers, faculty, and decision makers and provide a framework for the development and implementation of viable, adaptive retention initiatives and strategic plans.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
