This paper explores using the LearningApps.org online resource and information devices such as computers, interactive whiteboards, tablets, smartphones, and websites in teaching Biology in secondary school. An experimental methodology involving LearningApps.org exercises, smartphone apps, interactive whiteboards, and websites was developed and tested. The methodology aims to increase the effectiveness of biology education by leveraging educational technology. Experiments conducted in secondary schools demonstrated increased learning outcomes in plant morphology, anatomy, physiology and systematics topics. The use of multimedia and interactive exercises facilitated the learning process. Results highlight the benefits of integrating online learning tools with traditional classroom teaching. The methodology provides a model for modernising biology instruction through technology.
