Systematic Literature Review of the Use of Rich Media in STEM and Related Education

The use of video in pedagogy is well established in the modern classroom with researched understanding of its benefits. Prior literature reviews provide a foundation for the impacts within a wide scope of environments and subjects. These reviews primarily have looked at students and faculty attitudes, learning outcomes, and the impact on attendance. The impact has been spread over general subject matter with little focus on the often challenging topics of STEM education. Many topics in STEM education are highly procedural, such as mathematical proofs or writing code or conducting experiments. Understanding the costs and benefits of using video to capture these types of topics would be valuable in maximizing the benefits or avoiding concerns within STEM topics. This systematic literature review looks at the use of lecture capture and rich media within STEM and related education by looking at 30 articles from educational and STEM focused databases. Articles were selected which include findings on student and faculty attitudes, attendance, and learning outcomes as well as the impact of video and its best practices found through research. The findings within the STEM literature largely align with prior literature reviews in other subjects: video is popular among students and helps in their learning outcomes. Most research in this area focuses on video captured of the same lecture provided live in the classroom. This is shown to be effective, but some of the literature suggests further improvements to maximizing the value of both the technical merit of video as well as its pedagogical content. The goal is to determine the state of the use of video via lecture capture and prerecording in STEM education, its impact on students, and to gather recommendations and best practices from the literature

Does tagging improve the navigation of online recorded lectures by students?

Students more and more have access to online recordings of the lectures they attend at universities. The volume and length of these recorded lectures however make them difficult to navigate. Research shows that students primarily watch the recorded lectures while preparing for their exams. They do watch the full recorded lectures, but review only the parts that are relevant to them. While doing so, they often lack the required mechanisms to locate efficiently those parts of the recorded lecture that they want to view. In this paper, we describe an experiment where expert tagging is used as a means to facilitate the students’ search. In the experiment, 255 students had the option to use tags to navigate 18 recorded lectures. We used the data tracked by the lecture capture system to analyze the use of the tags by the students. We compared these data to studentswho did not use the tagging interface (TI). Results showthat the use of the TI increases in time. Students use the TI more actively over timewhile reducing the amount of video that they view. The experiment also shows that students who use the TI score higher grades when compared with students who use the regular interface.10000-01-0

Strategies to Improve Employee Ethical Conduct in Health Care Organizations

Organizational leaders face challenges related to implementing ethical standards, which influence performance, organization sustainability, and culture. The purpose of this single case study was to explore ethics strategies that health care business leaders used to improve employees\u27 ethical conduct. Data were collected through face-to-face, semistructured interviews with a purposive sample of 7 business leaders of a health care organization located in central Georgia and a review of organization documents. The conceptual framework was Brady\u27s Janus-headed model of ethical theory. Using a priori coding during the data analysis process provided 3 thematic categories: policy strategies for the improvement of employee ethical conduct, ethics strategies used to address employee unethical conduct, and strategies to overcome barriers of strategy implementation. Themes that emerged from the data were accountability and responsibility, leadership development, escalating behaviors, and adapting to change. The findings from this study might contribute to social change by providing information about ethical strategies leaders used to improve employee ethical conduct, which can be used to influence individuals\u27 livelihood, stakeholders\u27 comfort level, and the well-being of the community
