Learning Interventions

This research reports the assessment of pre-service teachers’ reception and attitudes towards virtual laboratory experiments in Life Sciences with the aim of advancing adaptability to digital learning. Using sequential mixed-methods in a quasi-experimental design, 68 pre-service teachers in the 3rd year of a Bachelor of Education (B.Ed) program were surveyed before and after virtual learning interventions. This phase was followed by qualitative data gathering using focus group interviews with all participants. Findings from quantitative data analysis revealed a positive significant difference in pre-service teachers’ attitudes towards virtual laboratory experiments post learning interventions. From qualitative data pre-service teachers found the progression from using only traditional to including virtual experiments was useful in enhancing their conceptual understandings of Life Sciences concepts, convenience, inquiry-based learning, self-directed and autonomous learning. However, pre-service teachers noted that using virtual laboratories did not significantly develop their science process skills and as a result could not replace the experiences in a traditional biology laboratory. The implications of these findings project virtual laboratories as a supporting tool for experimentation in Life Sciences especially within and post the COVID-19 pandemic where issues of social distancing pose a threat to collaborative and inquiry-based science learning. Recommendations from these findings are discussed herein. Keywords: inquiry-based learning, life sciences, pre-service teachers, virtual laboratory experiments

The cutting-edge technology of virtual reality has changed almost every aspect of life in e-commerce, engineering, medicine, and entertainment. This technology has also made its way to the field of education in the form of virtual laboratories. A lack of student engagement and interest towards STEM subjects is reported in the literature. Several studies have been conducted to evaluate virtual reality in education, but these studies are limited in terms of participants and subject coverage. This study aimed to assess the effectiveness of virtual laboratories to develop student’s practical learning skills for secondary school physics. For this purpose, a desktop-based virtual laboratory application was developed based on the guidelines extracted from the literature. A user study was adopted as the main research method, and it was conducted with 184 students of 4 different schools. In each school, students were divided into two groups: experimental (used the virtual laboratory application) and control (used a physical laboratory). The data were collected through an academic quiz conducted at the end of the study. The mean score of the experimental group was 7.16, compared with 5.87 for the control group. The results revealed that the students’ learning using the virtual laboratory application was better compared with the control group. Interestingly, there was no significant difference in the performance of boys and girls in both groups. The usability questionnaire was also completed by 92 students of the experimental group to assess the application interface. The mean score was 73.5 (above average) with an internal consistency of 0.76. The participants found the virtual laboratory application to be user-friendly, easy to use, and supportive in learning.

The teaching and learning process in the laboratory is different from theory classes. The students get better knowledge and understanding of the concept when they perform experiments in the laboratory. The hands-on practice will help the students to remember the concept. However, the lack of facilities and limitations in the laboratory infrastructure may affect the student learning process. In India, few technical institutions lack adequate laboratory facilities, and hence, the government of India has started a new initiative called the virtual laboratory to overcome this issue. The Government of India provided funding to the premier institutions in India to establish virtual laboratory facilities to help the institutions which do not have sophisticated laboratory facilities. The advancement in IT and internet facilities helps this initiative. In this chapter, basics of virtual laboratories, different types of virtual laboratories, impact of virtual laboratories in students learning process, opportunities, and limitations of the virtual laboratories were discussed.

Real World Problems

Since real-world problems are complex a system model is usually required in advance to be built for such a problem to be properly investigated. Virtual laboratories constitute a special category of simulations and are based on models of physical laboratories and the experimental processes carried out therein. Similar experiments can be adapted to suit various learners’ needs if they can be transformed to satisfy the expected learning outcomes for each audience. We compare such experimental procedures using the Activity Diagrams which correspond to these experiments, in order to detect differences between them. These differences are, then, used for the required transformation of the experimental steps. The algorithm implemented uses a uses a BFS-like traversal to detect the differences between Activity Diagrams. The evaluation of the distance between the Activity Diagrams is carried out by the user and the possible needed transformation is decided to meet the learning outcomes in the educational environment selected by the user, educator or learner.

The engineering students understand the engineering concepts effectively when they conduct the experiments in the laboratory. Hence, laboratory is as important as theory; however, the ill-equipped laboratory facilities affect the students’ learnability. The virtual laboratories may help the students overcome the problems faced by them in the conventional laboratory. In India, educational activities during the middle of the semester were affected due to lockdown related to COVID-19. However, the theory classes were conducted online, and educational institutions are finding it difficult to complete the laboratory experiments due to closure of colleges for the students due to COVID-19 pandemic. Hence, we have conducted a faculty development programme for the engineering college faculty members on mechanical engineering virtual laboratories. Similarly, we have trained the mechanical engineering students on fluid mechanics virtual laboratory. We have taken feedback from the participants of these virtual laboratory training programme and analysed it. From the analysis we have observed that more than 90 per cent of the participants were happy about the virtual laboratory and they expressed that their learning process improved with virtual laboratory experiments. Also, they felt that the virtual laboratories can be used till the COVID-19 pandemic issues are solved. Since the vaccine for COVID-19 is not available yet, the virtual laboratories will help the mechanical engineering students to conduct the laboratory experiments for the academic year 2020–2021.
