Improving the quality of students' knowledge by using NIS LAB virtual laboratory works in chemistry lessons

This study examines how laboratory activities using the digital resource NIS LAB in chemistry lessons affect student learning. Student performance was compared based on the results of summative assessment for the first and second quarters. Students of the 7th and 8th grades of the Nazarbayev Intellectual School of Chemical and Biological Studies in Petropavlovsk were selected for the study.

The results of the study indicate that students were involved in the learning process and used virtual laboratory experiments with interest. The findings of the study include recommendations on the possibility of using digital laboratory work in chemistry lessons, since the use of virtual experiments helps develop students’ motivation for the subject, saves time on completing the experiment, and also teaches students to strictly follow instructions while performing practical work. The work included the introduction of virtual practical work into the learning process, aimed at stimulating active learning.

The results show that using the NIS LAB resource improves the quality of laboratory work more than using traditional instructions and performing experiments. Positive differences were found in all assessments, with students in the experimental group showing better results. The findings support the assumption that the NIS LAB resource should be included in the educational process, since it encourages students to carefully read the proposed instructions, facilitates the analysis of the information received and improves the quality of learning, which is the main task of the teacher in the lesson.
