Learning Biology Using Real Object, ICT, and Blended Learning to Improve Factual and Conceptual Knowledge

During the pandemic of COVID-19, online learning was introduced, and students' achievement decreased. This research aimed to find effect biology model by using real objects (RO), ICT, Blended Learning (BL) on students’ factual conceptual knowledge. The design a quasi-experiment with pretest posttest comparison group design. done in two senior high schools. Cluster random sampling used choose three groups RO, BL, involving teachers 139 students. instrument mainly tests test items were validated expert judgment an empirical test. Multivariate analysis applied difference models. results indicate that (1) RO gives highest knowledge, (2) ICT increases (3) BL improves both Therefore, it is concluded should use through improve
