ABSTRACT
This research studied the impact of integrating virtual laboratories in chemistry lessons among 22 pre-service teachers who were enrolled in a Bachelor of Education program, focusing on middle and high school science. These participants were systematically divided into an experimental group (EG) and a control group. Both groups engaged in the same organic chemistry lesson and subsequent lab session, the only difference being that EG received additional training via a virtual laboratory prior to the hands-on lab session. A survey, conducted both before and after the experiment, was utilized to measure participants’ attitudes towards the use of virtual laboratories. The quantitative data analysis revealed a significant positive shift in EG’s attitudes post-intervention, suggesting that virtual laboratory experiences enhance their learning and engagement. Specifically, participants exhibited improved understanding of the educational methodologies and heightened engagement during the physical lab work. However, no significant differences were observed between the two groups concerning the technical aspects of the experiments, implying that the virtual labs’ impact on perspectives about the technical components of a chemistry lab was consistent across both groups. These findings support the view of virtual laboratories as a viable supporting tool for science education, promoting technology integration into teaching practices to meet the demands of 21st century learning outcomes. This research concludes with recommendations for future studies to explore further the implications of virtual labs on various aspects of science education.

ABSTRACT
The aim of the study is to assess the extent to which WhatsApp Instant Messaging is used to teach chemistry and biology to the tenth-grade students. A mixed approach was used, whereby the authors drew on the content analysis model to analyze quantitative data. The sample consisted of 28 Palestinian tenth-grade students and their teachers, who used WhatsApp Instant Messaging for four months (the Spring semester of 2019). The collected data was divided into four categories: the nature of the message (instructional, organizational, or social); the form of the message (texts, pictures/graphs, voice recordings, videos, or link-sharing); the direction of communication flow (from a teacher to a student, from a student to a teacher, from a student to a student, or from a teacher to a teacher); and knowledge exchange. Our findings suggest that WhatsApp is used more for non-instructional purposes– particularly socialization– yet the portion of instruction-related messages was somehow enough to predict more effective future use of the application for teaching/learning purposes.

ABSTRACT
The purpose of the present study was to investigate the effectiveness of the Information and Communication Technology (ICT) based approach and the Laboratory Training Model of Teaching (LTM) chemistry. It strived to determine whether the ICT or the LTM would be more effective with respect to the male and female students’ overall as well as component-based achievement in chemistry and their retention of learning. The sample of the study consisted of 120 seventh standard students from two English-medium elementary schools in Mysore city, India. Four homogenous groups were formed randomly for the study and the effects of independent variables were tested under experimental conditions. The Test of Higher Mental Ability in Science (THMAS) was used to determine the homogeneity of the participants. After one month, the delayed posttest for achievement in chemistry was administered to determine the retention level of the students. The statistical techniques used to analyze the data were the independent sample t-test and two-way analysis of variance (ANOVA). The findings indicated that as far as the overall achievement in chemistry, component-based achievement, and retention of knowledge, comprehension, application, and skills are concerned, the ICT-based method of teaching chemistry was more effective than the LTM of teaching. The effects of gender varied according to comparisons.
