Summary — This article aims to explain the effective use of Google Classroom for online lab submission. Practical knowledge is one of the key attributes of graduates and is acquired effectively through laboratory work. The purpose of this article is to focus on improving the quality of laboratory work through online submission of laboratory work by students and effective and transparent implementation of laboratory rubrics by the teacher of the laboratory course. A comparison study of two different classes, one with online lab submission and the other with a traditional approach based on grades and originality of submitted lab work, is also discussed, along with some other advantages.

Laboratory learning is an important part of the program and helps students gain practical knowledge. “Learning by doing” is the main idea behind a laboratory course. The laboratory course is an integral part of the educational learning process, particularly in technical education. The lab class helps them understand the concept better and also allows them to explore their idea individually. In a theoretical course, discussing a design problem is always an end. But implementation issues and flaws in the design can only be effectively addressed after its implementation in the laboratory. Therefore, the effectiveness of laboratory course is very evident and hence it is necessary to take appropriate measures to ensure that the objective behind conducting a laboratory course is achieved and the learning process should be such that the efforts and contribution of each individual student must be meaningfully visible. This in turn will result in an effective and more transparent evaluation. The traditional process of submitting one's laboratory work is through a laboratory journal or laboratory register, and the evaluation will mainly depend on the quality of the hard copy of the laboratory work submitted subsequently and on timely submission. Thus, the main flaw in this system was that laboratory work was submitted later and thus gave students the opportunity to copy those of their peers if the problem statement was the same or to seek help from a peer instead of taking efforts during real lab time. Thus, the students' actual understanding could not be concluded through the grades they received. Additionally, keeping track of the number of times a particular work had been resubmitted due to changes or corrections was difficult, if not impossible, in the approach mentioned above. remove the obstacles mentioned above and to improve the evaluation process, a technique in which students submit the laboratory work during the laboratory course in a Google classroom and the related work which includes calculations, justifications or post-laboratory questions a little later was adopted. The teacher's first task is to create an online workbook for students to submit their work. In this article, we used Google Classroom as a tool for students to submit their work. The Google Classroomhas features that allow the teacher to share resources with students, create common assignments, accept upload of individual files for the same assignment, and individual grading. Additionally, it also allows the teacher and student to post which class members can respond. Another benefit of this tool was that a peer teacher could also be added to the same class.A. Creation, submission and evaluation via Google ClassroomGoogle Classroom is one of the applications in which anyone with a Google account can open a Google classroom. After creating the Google Classroom, students can be invited to join the class via email or purchase by sharing the class code (as shown in Figure 1). The lab manual with general instructions and lab descriptions for each lab can be uploaded to Google Classroom for student reference. For the submission of each laboratory assignment, two assignments were created and designated as Part 1 and Part 2. Students were asked to submit Part 1 before the end of the laboratory, which was ensured by assigning a assignment deadline via one of the Google Class features. The first part included observations and results. Part 2 of the assignment had to be submitted within a given deadline and included related literature such as calculations, graphs, conclusions drawn or post-lab questions. The teacher could evaluate the lab work at any time because it was always available on the cloud. . The documents uploaded by the students also had a time stamp, which helped the instructor to effectively implement the submission rubric in a timely manner. The teacher could also ask the students to rework the assignment returning a lower grade and the student could also resubmit the same grade, with everything recorded via Google Classroom. Timely assessment from the teachers' side was also recorded, which helped to quantify the term continuous assessment used in the assessment of laboratory work. At the end of the course, the collected information about students' work and grades was available and could be extracted into a downloadable Excel sheet.B. Comparing Submission of Contracted Online Lab Work to the Traditional Approach Effective Individual Submission: Since the individual had to submit the first part of their lab at the end of the lab, the student had very little opportunity to copy the work of others. Additionally, in the case of software simulation labs, each individual student had to associate a unique variable with their unique roll number and in the case of hardware labs, handwritten observations and noted results had to be uploaded. Ease of assessment and implementation of rubrics: The laboratory course for which we implemented this approach had a weighting of 25.
