COVID-19 Inspired a STEM-Based Virtual Learning Model for Middle Schools—A Case Study of Qatar

Teaching presence predicts cognitive presence in blended learning during COVID-19: The chain mediating role of social presence and sense of community

With the continuous lockdown and staying home strategies of COVID-19, both instructors and learners have met with the presence challenges in language learning. To address the complex and dynamic relationships of different presences in blended learning during COVID-19, based on the Community of Inquiry framework, 215 Chinese English learners were obtained as samples for an empirical test. SPSS 23 and PROCESS for SPSS were utilized to examine the hypotheses. Results indicate that teaching presence (TP) has a significant direct positive impact on social presence (SP), sense of community (SoC), and cognitive presence (CP). SP has a significant positive impact on CP and partially mediates the relationship between TP and CP. SoC is also found to impact CP and partially mediates the relationship between TP and CP. The findings also validate the chain mediating role of SP and SoC between TP and CP. Pedagogical implications are discussed.

A Distinctive Method of Online Interactive Learning in STEM Education

A breakthrough that has occurred in recent years is the emergence of the COVID-19 pandemic. It has affected various sectors of society, including the educational sector. It has prevented students from performing group-oriented hands-on activities and has eventually transformed their active learning environment in schools into virtual passive lectures at home. Therefore, to solve this impedance, we exercised several online STEM programs (five online STEM programs with repetitive cycles) for school students, including 140 students (middle and high school), 16 undergraduate (UG) secondary mentors, and 8 primary STEM professionals. Thus, the study revealed the results of a distinctive interactive online STEM teaching model that has been designed to overcome the virtual classroom’s impediments. The employed teaching model demonstrates an interactive learning environment that ensures students’ engagement, retention, and participation, driving them to STEM innovations. Various digital tools, including PowerPoint presentations, videos, online simulations, interactive quizzes, and innovative games were used as teaching aids. Both the synchronous and asynchronous means in a student-centered approach, along with the feedback mechanism, were implemented. Finally, the employed method’s effectiveness was revealed by the maximum student retention and STEM innovation rates, along with the model’s potentiality towards its replicability and sustainability. Thus, the outlook of such initiatives could further be broadened by its sustainability and replicability aspect towards vulnerable student communities such as academically introverted and specially challenged students.
