The Effectiveness and Efficiency of Google Classroom as an Alternative Online Learning Media to Overcome Physical Distancing in Lectures Due to the Covid-19 pandemic: Student Perspectives

In mid-March 2020, WHO declared Covid-19 a global pandemic that all countries must pay attention to prevent wider transmission. Therefore, the Indonesian government appealed to the public to exercise physical distance and appeal to work from home to prevent the spread of the virus. Google provides facilities that can be used as online learning with a virtual classroom concept that can be used for distance learning between lecturers and students. In this research, we will discuss the level of effectiveness and efficiency of an online learning application called Google Classroom. The data used to analyze the effectiveness and efficiency of online learning with Google Classroom came from a student perspective questionnaire using the Likert scale method for positive questions and specific questions for theoretical subjects with 120 respondents from the UNESA electrical engineering department. We also propose blended learning signs when this pandemic has ended. The results obtained are according to the cumulative calculations that have been described in the graphical modeling, namely the highest percentage of 88% of students stated their agreement with the efficiency of online learning on time availability. Meanwhile, the level of effectiveness of online learning on the ease of the GC user interface with a majority percentage of 85% agreed. But if online learning refers to learning targets, the percentage obtained from a student's perspective is 37%, which is still low. If the pandemic has ended, we also get data results on blended learning planning on the use of GC, the majority of 60% of students agree.
