Analysis of google classroom utilization as a tool to enhance blended learning in federal polytechnic Mubi Amidst Intense Security and COVID-19 Challenges Hyellamada Simon * , Ireti Hope Ajayi and Wadzani A. Gadzama Department of Computer Science, Federal Polytechnic Mubi, Adamawa State, Nigeria. World Journal of Advanced Research and Reviews, 2022, 14(02), 018–023 Publication history: Received on 25 March 2022; revised on 28 April 2022; accepted on 30 April 2022 Article DOI: https://doi.org/10.30574/wjarr.2022.14.2.0378 Abstract Teaching and learning have improved in the twenty-first century as numerous pedagogical technologies have been produced to support learning throughout the universe, where traditional classrooms have been turned into virtual classrooms to facilitate blended learning. The Nigerian education system has suffered a setback as a result of the COVID- 19 pandemic and the country's strong insecurity concerns, both of which have had a significant impact on the country's education system, making it harder for students and teachers to collaborate in learning. This paper aimed to analyze the utilization of Google Classroom as a tool for teaching and learning in the Federal polytechnic Mubi. The study used a total of 475 questionnaires to collect data from Lecturers of the institution, and a simple percentage was used to analyze the results. Our findings revealed that 55% of the respondents believed that Google Classroom made it easy to upload course materials to students, 65% also believed that Google Classroom made it easy to grade students’ assignments/quizzes, and 61% likewise attested that Google Classroom was of great significance in timely completion of course delivery and assessment. Therefore, this paper concluded that Google Classroom was utilized in the Federal Polytechnic Mubi amidst insecurity and COVID-19 challenges. The paper recommends the adoption of Google Classroom as a tool to enhance blended learning in Nigerian tertiary institutions.

Introduction In the 21 st century, teaching and learning have advanced from traditional classrooms to virtual classrooms due to advancements in technology and various innovations in pedagogy. This is possible due to the inventions of internet- enabled devices such as computers and mobile devices which offer new prospects for teaching and learning beyond the traditional classrooms in tertiary institutions. Thus, Seamless learning connects private and public learning areas, allowing students to learn through both individual and group efforts, as well as across time and situations (such as in school vs after-school, formal vs informal learning, physical world vs. virtual reality or cyberspace). Formal learning is often described as learning that occurs at a set time and follows a predetermined curriculum or plan. Informal learning, on the other hand, refers to learning that takes place outside of the classroom and is emergent [1]. Similarly, research by [2] revealed that asynchronous communication seemed to enable in-depth communication among learners with previous training in computers who were more satisfied with online courses than students who hardly used the computers.
