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.

Previous studies on the effectiveness of virtual laboratories for learning have shown inconsistent results over the past decade. The purpose of this research was to explore the effects of a virtual laboratory and meta-cognitive scaffolding on students' data modeling competences. A quasi-experimental design was used. Three classes of eighth graders from southern Taiwan participated in this research and were assigned to the Experimental Group Ⅰ (EG Ⅰ), the Experimental Group Ⅱ (EG Ⅱ), and the Control Group (CG). EG Ⅰ (n=25) received the virtual laboratory and meta-cognitive scaffolding in the teaching and learning. EG Ⅱ (n=28) received the virtual laboratory only in the teaching and learning. The CG (n=27) received the lecture with the cookbook laboratory. The teaching unit was Heat and Specific Heat, and the teaching time for the three groups was six lessons (of 45 minutes each). The Data Modeling Competences Test (DMCT) designed by the research team was used as the data collection instrument. The results showed that the virtual laboratory and meta-cognitive scaffolding had effects on students' data modeling competences. This research shows the importance of the meta-cognitive scaffolding strategy for virtual laboratories when conducting data modeling teaching.

Important Means

Online learning has gained substantial traction since the popularization of Massive Open Online Courses (MOOCs) over the last decade. After the dawn of the Covid-19 pandemic, online learning has become an indispensable mode of modern-day education. All educational institutions around the world are now compelled to switch to online classes as a physically safer and more flexible option for teaching and learning during the pandemic. Although many studies have examined the effectiveness of this online T&L mode, almost no attention has been paid to the use of virtual laboratories, which are an important means of teaching practical skills and complicated theories for science and engineering subjects. Like other online methods that have their particular advantages and disadvantages, the utility of virtual laboratories is detracted by the fact that they lack some of the qualities present in the actual experiments seen in traditional learning classrooms. In particular, virtual labs are not as effective as authentic lab experiments in developing soft skills that are typically acquired from students’ teamwork activities, in addition to lacking the ability to assess the various levels of knowledge acquisition, content mastery and student attention in class. Hence, the aim of this paper is to address these issues about the utility and drawbacks of virtual labs in achieving the long-term goals and learning outcomes of STEM education. In addressing these issues, the paper highlights the varying technologies, such as gaming and virtual reality, used by different educational institutions as substitutes for physical engineering laboratories. The final section of the paper discusses some of the ethical issues related to online learning for science and engineering subjects.

Questioning Strategies

The aims of the study were to investigate English teachers’ questioning strategies at one Madrasah in Palembang, South Sumatera. The qualitative research method with a case study approach was employed to look at the ways of the English teachers’ questioning strategies in the processes of teaching and learning and the reasons that made them use certain questioning strategies. The participants in this study were English teachers. We used observation and interviews as our data collection techniques. The observation was used to look at the teacher’s questioning types used in the daily practices of teaching in the EFL classroom while the interview was used to understand the reasons that made them use those types of questioning strategies. Our findings showed three types of teacher’s questioning strategies used by teachers in their teaching and learning processes including convergent, divergent, and procedural questions. Teachers mostly used convergent questions (yes/no and short answers). We also found five reasons why teachers preferred to those types of questioning strategies including recalling students’ understanding, attracting students’ attention, increasing students’ thinking in higher order level, and engaging students in learning activities. Implications and recommendations are also discussed.
