The laboratory is the main means of learning contextual physics. The results of observations in high schools of Padang Pariaman Regency, West Sumatra, showed that the implementation of laboratory activities in learning physics was still low. An analysis was conducted to highlight the implementation of these laboratory activities in high school physics learning in terms of teachers’ and principals’ perceptions. Aspects that can be disclosed are a) the implementation of laboratory activities in terms of; availability of infrastructure and perceptions of teachers and school principals on laboratory activities, and b) the relationship between teachers’ and principals’ perceptions of laboratory activities in physical education. Sampling was done using the Cluster Random Sampling technique. The data obtained were described using the percent technique. The results of data analysis and processing concluded that a) in terms of the availability of facilities and infrastructure for the implementation of laboratory activities, the average was in the very low category (17.86%), b) The perception of teachers and principals on laboratory activities in physical learning was on average the same for the lower criteria (43.00%) and 45.20%); and c) data on the relationship between the perceptions of teachers and principals on laboratory activities is in a very strong (0.816) and strong (0.788) relationship with their respective contributions of 66.60% and 62.10%. In general, this analysis concludes that a very low percentage The implementation of laboratory activities is largely influenced by the low perception of teachers and principals’ perceptions of the role of laboratory activities in learning physics.
