Laboratory experimentation in the context of school science is a widely advocated teaching strategy for the simplification of several abstract scientific concepts. Laboratory-based learning activities have proven to enhance learners’ conceptual and procedural understandings of micro chemical phenomena, thus boosting achievement in chemistry content tests. In the South African education landscape where there is inequitable distribution of resources for laboratory-based science learning, this study exploited how available virtual learning resources could also be used for learning chemistry concepts, and further compared student achievement in chemistry content test post intervention with both traditional and virtual laboratory learning resources. In this quasi- experimental study, we provided a group of third-year pre-service science teachers (n=50) with four chemistry concepts to learn using a hands-on traditional (control group) and a virtual laboratory (experimental group) intervention. The same pre and post chemistry content test was administered to control and experimental groups of pre-service teachers (herein also referred to as students), before and after learning interventions, with the aim of assessing students’ achievements post- learning in the two different laboratory environments. Tests scores were analysed and the results of a paired-sample t-test showed a statistically significant difference between pre- and post-test results for all groups of students. Using independent sample t-tests, we further compared post-test scores for the control and experimental groups which revealed the mean post-test score of the experimental group (M = 79.36, SD = 8.306), being significantly higher than that of the control group (M = 68.72, SD = 9.076) at t (48) = 4.32, p < .01. The findings from these tests indicated that, students obtained significantly higher achievement scores post- laboratory learning interventions and that virtual laboratory interventions yielded significantly higher achievement scores than traditional laboratory interventions. Based on these findings, the researchers concluded that, laboratory learning has a positive impact on achievement in chemistry and that virtual laboratories provide a worthy complement for traditional laboratories when learning abstract and difficult chemistry concepts. Implications of these findings and some recommendations for practice and research are also discussed herein.

Laboratory experiments are considered to be a crucial component of engineering and science curricula by all stakeholders in the education process. In traditional laboratories, students develop practical skills and become effective professionals. However, the major drawbacks of traditional laboratories are their high demand on resources, significant maintenance costs and the inability to delivery the laboratory content in distance education. Virtual laboratory experiments represent a valuable option for educational laboratories, due to their advantages over traditional hands-on as well as remote experiments, including the ease of reconfiguring the experimental system, the high flexibility in the input specifications, the possibility of conducting experiments using devices otherwise infeasible and the option of re-running experiments multiple times.&#x0D; In response to the need for developing laboratory resources that provide a practical experience to online engineering students, this paper describes a simulation-based virtual laboratory, which is used at Stevens Institute of Technology (SIT) in a junior-level course on mechanisms and machine dynamics as a compliment to experimental work in the traditional hands-on laboratory. This virtual laboratory system alleviates the space, time and cost constraints associated with traditional laboratories and serves as an efficient teaching aid. It conveys to the students practical issues associated with actual experiments and provides learning outcomes that are comparable to those of traditional physical laboratories. The students have the opportunity to explore a wide range of experimental configurations and parameters. In addition, the system includes a realistic rendering of the experimental setup and its components, thus providing the students with a strong feeling of immersion, as if they were performing an experiment in a traditional laboratory.

Facilitating the Creation of Virtual and Remote Laboratories for Science and Engineering Education

The emergence of problems such as the COVID-19 pandemic that currently occurred interfere the implementation of teaching and learning activities in schools. Especially for science learning, it is not only about the content but also the processes to improve student’s skills, such as science process skills. Current technological advances make it possible to conduct distance learning using media such as virtual lab. This study aims to review the comparison of the effectiveness between virtual lab and traditional lab, the use of virtual lab on student’s science process skills, and the use of virtual lab as a medium of distance learning. This study uses a systematic literature review method with 22 selected articles. The results indicate that the use of virtual lab media has the same or even better effectiveness than traditional labs. The use of virtual lab enable to enhance student’s science process skills, especially in predicting and measuring. This is because the virtual lab media able to provide opportunities and flexibilities for students to conduct experiments by the level of ability and pace of learning each student, anytime and anywhere. Thus, the virtual lab media is feasible to be used as an alternative substitute method for distance learning.

Science is a practical subject that requires experiments in labs to provide hands-onexperience. Virtual labs act as complementary to traditional Labs. In the 21st century, there is a high need for digital transformation. Virtual Labs act as an alternative method of innovative pedagogy. NEP 2020 recommends to use innovative pedagogy in the classroom and digital tools are promoted that will lead to sustainable use of resources and promote inclusive education. Traditional Labs are sometimes not well equipped, and virtual labs play an important role in fulfilling societal needs. Secondary school students are being taken as a sample of study to check out the effectiveness of virtual labs. It is found that the maximum number of students are unaware of the virtual labs and their effectiveness. The features of virtual labs and their implications in comparison to traditional labs are explored. Various platforms where learners can access the virtual labs are explored. Virtual laboratory are very helpful in the Science education which can increase self paced learning and it is something new for the learners so create a new , innovative and motivating factor as this is new and students participate actively in this as this is apart from their monotonous routine and provides experience of the theoretical concepts and lab equipments.

Ever since the COVID-19 pandemic, higher education witnessed a paradigm shift in the teaching-learning strategies everywhere from the original way where everything was largely conducted face-to-face. Teachers, educators, and students had to suddenly move to the virtual mode to continue their classes in schools, institutes, and universities. Recently, many published studies have revealed the utmost need to improve teaching strategies, particularly in an online lecture setting. However, the major impediment was observed in higher educational institutions (HEIs) where teachers had to conduct laboratory experiments in hard sciences, particularly in physics, chemistry and, biochemistry. Of these subjects taught in graduate classes, chemistry is a complex subject. A chemistry learner needs to acquire hands-on experience, especially when performing organic preparations and instrumental analyses. Chemistry teachers believed that nothing could ever replace a traditional laboratory setting, but now the situation has changed to a certain extent. It has always been argued that students do not learn by merely clicking on simulated glassware and instruments. In a typical organic chemistry laboratory, students prepare organic compounds, purify them, and determine various properties of the pure compounds. Students gain experience by trial-error while adding reagents in organic preparation, devising reaction mechanisms, observing the physical properties of purified compounds, and even separating complex mixtures. Virtual laboratories cannot replace all these with a mere simulator, but when one deals with corrosive chemicals and advanced instrumental methods, it seems a plausible solution to augment them with traditional laboratories. It was found that using advanced level of online screen experiments improved students understanding and also helped them score well in their laboratory assessments. Virtual simulations cannot replace traditional laboratories since many experiments require hands-on tool abilities, smelling, seeing colored complexes, and trial-error strategies. It was also observed that experiments that require costly instruments can be carried as a remote trigger, paving the way to augment virtual experiments in the future chemistry laboratory. The chapter discusses the pedagogical design for graduate students in a virtual chemistry laboratory and live demonstrations performed in the traditional laboratory. In this chapter chemistry experiments based on organic synthesis, stereochemistry and spectroscopy on a virtual screen have been studied. The different modalities of conducting virtual screen experiments, assessment strategies, and government initiatives are also highlighted. This chapter concludes with current and future trends of virtual chemistry laboratories with highlights on the barriers, opportunities, and key measures to resolve them.

BACKGROUND Experimentation is crucial in chemistry education as it links practical experience with theoretical concepts. However, practical chemistry courses typically rely on real laboratory experiments and often face challenges such as limited resources, equipment shortages, and logistical constraints in university settings. To address these challenges, computer-based laboratories have been introduced as a potential solution, offering electronic simulations that replicate real laboratory experiences. OBJECTIVE This study examines the effect of virtual laboratories on the academic achievement of undergraduate chemistry students and evaluates their potential as a viable alternative or complement to traditional laboratory-based instruction. METHODS A quasi-experimental design was implemented to examine the cause-and-effect relationship between instructional methods and student outcomes. The study involved 60 fourth-year BSc chemistry students from Dilla University, divided into 3 groups: a real laboratory group (n=20), which performed real laboratory experiments; a virtual group (n=20), which used virtual laboratory simulations; and a lecture group (n=20), which received lecture-based instruction. Quantitative data were collected through tests administered before and after the intervention to assess academic performance. The data analysis used descriptive and inferential statistics, such as means and SDs, 1-way ANOVA, the Tukey honestly significant difference test, and independent-sample &lt;i&gt;t&lt;/i&gt; tests (2-tailed), with a &lt;i&gt;P&lt;/i&gt; value of .05 set for determining statistical significance. RESULTS Before the intervention, the results indicated no significant differences in academic achievement among the 3 groups (&lt;i&gt;P&lt;/i&gt;=.99). However, after the intervention, notable differences were observed in student performance across the methods. The real laboratory group had the highest mean posttest score (mean 62.6, SD 10.7), followed by the virtual laboratory group (mean 55.5, SD 6.8) and the lecture-only group, which had the lowest mean score (mean 43.7, SD 11.5). ANOVA results confirmed significant differences between the groups (&lt;i&gt;F&lt;/i&gt;&lt;sub&gt;2,57&lt;/sub&gt;=18.429; &lt;i&gt;P&lt;/i&gt;&lt;.001). The Tukey post hoc test further revealed that the real laboratory group significantly outperformed the lecture-only group (mean difference 18.88; &lt;i&gt;P&lt;/i&gt;&lt;.001), while the virtual laboratory group also performed significantly better than the lecture-only group (mean difference 11.7; &lt;i&gt;P&lt;/i&gt;=.001). However, no statistically significant difference was found between the real laboratory and virtual laboratory groups (mean difference 7.12; &lt;i&gt;P&lt;/i&gt;=.07). In addition, gender did not significantly influence performance in the virtual laboratory group (&lt;i&gt;P&lt;/i&gt;=.21), with no substantial difference in posttest scores between male and female students. CONCLUSIONS These findings suggest that computer-based laboratories are a viable and effective alternative when real laboratories are unavailable, enhancing learning outcomes when compared with traditional lecture-based methods. Therefore, universities should consider integrating computer-based laboratories into their practical chemistry curricula to provide students with interactive and engaging learning experiences, especially when physical laboratories are inaccessible.

The study aimed to identify the extent to which the virtual laboratory is used in science teaching and its obstacles from the point of view of science teachers in the Southern Jordan region. The male and female teachers were randomly selected. The results of the study showed that the extent to which science teachers use the virtual laboratory came to a medium degree with arithmetic mean (2.83), and the obstacles faced by science teachers in using the virtual laboratory came to a large degree and arithmetic mean (3.91), and the results also showed that there were no statistically significant differences for the extent of the use of the laboratory The default according to the variables: (gender, educational qualification, and work experience). The study recommended the necessity of holding courses and workshops for teachers and students to develop their attitudes towards the virtual laboratory, training them on the methods of using it, and providing virtual laboratories to include all schools.

Initiated during the Covid-19 pandemic, this study examines the development and use of virtual laboratories at 'Universitas Terbuka' to facilitate science practicums. Initially a response to pandemic restrictions, these virtual labs proved to be invaluable due to the widespread geographic distribution of students across the Indonesian archipelago. As the world transitions to a new normal, with possibilities for on-site practical experiences resuming, this paper discusses how virtual labs can continue to ensure equitable access to practical science education. This aspect of equal opportunity in education, whether online or on-site, is termed 'scalable practicum' in this study. By using a combination of qualitative and quantitative research methods, the paper evaluates the effectiveness of these virtual labs in providing hands-on scientific experimentation experiences that are both accessible and flexible. The findings suggest that, even beyond pandemic constraints, virtual labs remain a feasible and efficient alternative to traditional in-person labs, significantly enhancing student engagement and learning outcomes. This paper emphasizes the adaptability of virtual labs to various learning contexts and their importance in the evolving landscape of science education. The study concludes by recommending further research with a broader demographic to thoroughly evaluate the long-term viability and impact of online scalable practicums in science learning.

The current research aims to identify the impact of an instructional package based on a virtual lab on the achievement of first-year intermediate school students in chemistry. To achieve the research objective, the following null hypothesis was formulated: "There is no statistically significant difference at the 0.05 level of significance between the mean scores of the experimental group students who study according to an instructional package based on a virtual lab and the mean scores of the control group students who study according to the traditional method in chemistry achievement." The quasi-experimental design with partial control (an experimental group and a control group) with unequal numbers and a post-test in achievement was chosen. The sample consisted of 66 students from Al-Qadisiyah Intermediate School for Boys, selected randomly. The experimental group consisted of 34 students who studied according to the instructional package based on a virtual lab, and the control group consisted of 32 students who studied according to the traditional method. The experimental and control groups were equalized in terms of variables: age (in months), general average grades for the sixth grade, prior knowledge, and parental education level. A total of 24 daily teaching plans were prepared for both the experimental and control groups. The teaching plans for the experimental group were organized according to an instructional package based on a virtual lab, while the teaching plans for the control group were organized according to the traditional method. The data were statistically processed using the SPSS package for two independent samples with unequal numbers. The results showed that the experimental group, which studied according to the instructional package based on a virtual lab, outperformed their peers in the control group, who studied using the traditional method in the achievement test. Therefore, the current study recommends using an instructional package based on a virtual lab in teaching chemistry and suggests conducting further studies on different stages and subjects to identify its impact on various variables.

With the world wide acceptance of virtual educational technologies, it has been shown that they play a vital role in the scientific arena. The purpose of this paper was to analyze the role of Biotechnology virtual laboratories in integrating student’s learning ability and introducing it as an effective instructional tool in biotechnology courses. A post-usage survey was conducted among the users and included questions about perceptions of virtual laboratories, its role in virtualization of sophisticated instruments. The survey suggested virtual labs usage enhanced autonomous and guided educational methods. Comparing groups on usage of virtual labs against a control (traditional lab), our studies suggest improved performance in students using virtual labs. Usage analysis and surveys indicated that biotechnology virtual labs are significant elements in adaptive learning process in blended classroom environment.

The interest on educational remote laboratories has increased, as have the technologies involved in their development and deployment. These laboratories enable students to use real equipment located in the university from the Internet. This way, students can extend their personal learning experience by testing with real equipment what they are studying at home, or performing hands-on-lab sessions at night, on weekends or whenever the traditional laboratories are physically closed. A unique feature of remote laboratories when compared to traditional laboratories is that the distance of the student is not an issue, so remote laboratories can be shared with other schools or universities. In this contribution, authors present and discuss a widely spread remote laboratory (VISIR, present in 6 european universities + 1 in India) shared among 3 institutions (2 universities + 1 high school). During the exhibition, demonstration of the laboratories being shared will be shown.

With recent advances in information technologies, a new mode of laboratory known as the “virtual laboratory” has begun to revolutionise engineering education. This development has generated discussion about the fundamental learning outcomes of laboratory training courses and, ultimately, an interest in the consequent changes to the student’s learning experiences.This exploratory case study describes the initial phase of a research agenda that is focused on investigating the effectiveness of virtual laboratories in the Department of Electrical and Electronic Engineering (EEE) in a research-intensive university. The long-term goals of the agenda are to add to the literature of how effective virtual EEE laboratories are (in terms of delivering specific learning outcomes, and also engaging and motivating students and teachers), and to discover whether they can ultimately become a substitute for traditional laboratory training by providing an equivalent and comparable learning experience for students.

The virtual simulation laboratory is a process of transforming the one-dimensional text on the original textbook, to the two-dimensional picture projected by PPT, into a lifelike three-dimensional image.
