ABSTRACT
Educational robotics has been adopted to create interactive and engaging learning environments to develop computational thinking (CT) in K-12 learners. This study systematically examined 22 peer-reviewed empirical research articles on the use of educational robotics to develop CT in young learners (pre-kindergarten to 6th grade) published between 2012 and 2021. The findings revealed that using robotics activities to develop CT has mostly been studied in the formal education settings with the duration of robotics curricular activities ranging from 80 minutes to 24 hours. The five CT skills studied most often include Sequencing, Conditionals, Loops, Debugging, and Algorithmic Thinking. The different versions of LEGO Mindstorms are the most frequently adopted robotic kits in the examined studies. The most frequently adopted learning and instructional strategies in the robotics activities include collaborative learning, project-based learning, and embodied learning. This paper identified and discussed developmentally appropriated CT skills, robotics kits, and pedagogical approaches suitable for supporting CT development in young learners. The findings can guide educators and instructional designers for future robotics activity design and development endeavors. This paper also identified gaps in the current research and recommended directions for advancing research in adopting robotics to develop CT in young learners.
ABSTRACT
While the use of virtual manipulatives (VM) is rising in classrooms, there is still limited research. regarding teacher experiences with and perceptions of virtual manipulatives. Most of the research regarding teacher perceptions of VM has focused only on short-term uses following professional development sessions and none has highlighted the experiences of teachers using them during emergency remote teaching during COVID-19. The purpose of this study was to explore teacher perceptions and. experiences with virtual manipulatives following emergency remote teaching during COVID-19. To achieve this, the researchers conducted an online survey to gather data on educator's (n = 103) experiences, perceptions, and usage of virtual manipulatives. The qualitative and quantitative data show that educators feel that VM are a valid and feasible support of mathematics instruction when physical manipulatives are not available. Results regarding usage of virtual manipulatives including frequency of use, standards taught, and types used are presented and discussed.

ABSTRACT
Discussion boards can provide a glimpse into the regular and substantive interaction required in online courses. Advances in technology and an increased interest in learning analytics now provides researchers with billions of data points about instructor and student interaction within a learning management system (LMS). This study used LMS data to explore the frequency of interaction between instructors and students in discussion boards in online courses at one institution. Overall, 415 courses were analyzed spanning two semesters. Results from the study found that the average number of posts by an instructor was 32.9. The average instructor interaction was 1.49 instructor posts per student. 23% of courses had no instructor posts. Student posts averaged 470 per course and the average posts per student was 19.9. Based on the discussion board activity, the most discussion interaction occurred during the first two weeks of the semester. Results also suggested that there is no relationship between student satisfaction and the number of total posts in a course. The paper concludes with implications for research and practice.
