Abstract
The purpose of writing this paper article is to review students' perceptions in the use of PhET-based virtual labs and also to provide a description in comparison to perceptions of virtual lab use from some of the results of previous studies that are relevant to this study. There are five aspects in the perception that will be surveyed, including; (1) aspects of innovation, (2) aspects of benefits (3) aspects of motivation, (4) aspects of effectiveness, (5) aspects of presenting procedures for laboratory activities. The method used is quantitative and qualitative with a Likert scale questionnaire which must be filled in by 40 people and then interviewing the subjects, after the data is collected, percentage data analysis is carried out. The results of the data analyzed show that the aspects of innovation, effectiveness, benefits and presentation of the procedure get a positive view compared to the motivational aspects which are stated to be negative, so this study also shows that the use of virtual labs based on PhET is innovative and effective, but lacks motivation in its use because of essential activities. laboratory is not felt, in presenting the module is required to increase 4C Skills to support 21st century skills
Highlights
Laboratory activities are a framework of process that includes planning, discovering facts, collecting data, classifying, obtaining conclusions and interpretations, sometimes with the intention to immerse students into the process of scientific investigation (Putra et al, 2021)The introduction of Information and Communication Technology (ICT) among educational institutions and college students has opened a new window into the world of practicum-based learning
The students carry out laboratory activities based on the inquiry guided laboratory module that has been made and verified by previous media and material experts
When they have carried out virtual laboratory activities with PhET media, students are given a questionnaire and being interviewed
Summary
Laboratory activities are a framework of process that includes planning, discovering facts, collecting data, classifying, obtaining conclusions and interpretations, sometimes with the intention to immerse students into the process of scientific investigation (Putra et al, 2021)The introduction of Information and Communication Technology (ICT) among educational institutions and college students has opened a new window into the world of practicum-based learning. In addition to the traditional laboratory, students can carry out or be involved in a virtual laboratory activity which is supported by a computer instead of a smartphone. A teacher or lecturer is required to be able to use ICT tools to show students something without any access to the actual resources. A traditional laboratory (TL) research's objective can be defined as an active activity by using real objects and instruments to observe object and its process. If an instrument is used, an object that stands alone (independent) and cannot be utilized directly or the distance is very far, the virtual lab is the alternative. The use of virtual labs is to enable personal computers as an interactive experimental simulation (Špernjak & Šorgo, 2018)
