Abstract
The expectations within higher education to improve online STEM courses have continued to increase. The pressure to do so particularly pertains to the lower-level introductory courses that act as gatekeeping courses to various STEM-related majors. Rather than working alone to improve their courses, more instructors for these courses pair with the respective instructional designers at their institutions to refresh or revise, their online courses. This study examines the revisions of a two-part introduction-to-biology series of online courses with their respective online labs over the span of three years, and from a sampling of 905 students, compares the final scores from the courses and the labs between each iteration. Findings indicate that multiple iterations of a course have the potential to increase student outcomes and to decrease the student dropout rate over time. Additionally, purely online students can perform differently in response to course revisions in comparison to the online students who also enroll in non-online courses, implying that the needs of online-only students may differ from those who have a blended learning experience.
期刊介绍:
The objective of this journal is to publish original, fully peer-reviewed articles on a variety of topics and research methods in both science and mathematics education. The journal welcomes articles that address common issues in mathematics and science education and cross-curricular dimensions more widely. Specific attention will be paid to manuscripts written by authors whose native language is not English and the editors have made arrangements for support in re-writing where appropriate. Contemporary educators highlight the importance of viewing knowledge as context-oriented and not limited to one domain. This concurs with current curriculum reforms worldwide for interdisciplinary and integrated curricula. Modern educational practice also focuses on the use of new technology in assisting instruction which may be easily implemented into such an integrated curriculum. The journal welcomes studies that explore science and mathematics education from different cultural perspectives.
