Existing research on online labs focuses heavily on computer‐supported inquiry learning environments, such as virtual laboratories and remote laboratories. There are limited studies on kitchen labs or home labs. Objectives: This study investigated the effectiveness of home labs using lab kits from two perspectives: students' perceptions and experiences of labs conducted in a home environment, as well as whether home labs help with students' knowledge acquisition. Methods: This study employed lab quizzes to assess students' performance and lab reports to evaluate students' ability to interpret the lab results accurately in the authentic home lab contexts. Surveys and semi‐structured interviews were used to collect students' perceptions and experience data regarding these hands‐on experiments at home. Results and Conclusions: We found that students' perceptions of home labs are similar to that of face‐to‐face labs, but they generally perceive home labs to be less complex. Students' performances on lab quizzes and lab reports indicate that the majority of them were able to apply the key scientific concepts to accurately interpret lab results in authentic home lab contexts. Students perceived that home labs provide flexibility and help in connecting learning to the real world. However, they also face challenges such as unexpected results and ambiguity during the process. Implications: Based on the key findings from this study and our reflections, four practice guidelines were provided for teaching hands‐on experiments online. Lay Description: What is already known about this topic: Science‐laboratory activities play a critical role in science education. The lack of best practices for teaching science laboratory activities online has become one of the most significant barriers to online education.Existing online labs research focuses heavily on computer‐supported inquiry learning environments, such as virtual laboratories and remote laboratories. There are limited studies on kitchen labs or home labs and some research has mainly an exploratory nature. What this paper adds: The value of authentic hands‐on learning experience is more than the acquisition of laboratory design skills, but also the acquisition of problem‐solving skills in real‐world.This study reported findings of the evaluation of hands‐on home laboratory activities in an online science course from both students' perception and their knowledge acquisition perspectives.This study also explored the benefits and challenges students faced in home labs. Implication for practice and/or policy: Practical guidance and implications for teaching and learning science online using laboratory activities were provided by sharing our experience and lessons learned through the whole process.We recommend that practitioners incorporate more scaffolding and peer collaboration opportunities as well as key concept reflection as teaching strategies to improve the effectiveness of home lab activities. pubtype: Academic Journal doctype: pictorial research tables/charts Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
