The research was carried out in a regular chemistry class, in a five-week intervention with the Mole Unit. The blended learning consisted of students watching videos at home, school or both and then working with classroom activities that fostered active learning. The results indicated that blended learning, use of visual aids and homework reinforced the knowledge learned in class and prepared students for exams.enChemistryHigh school studentsBlended learningFlipped classroomsLearning disabilitiesProfessional PaperCopyright 2020 by Perla Alvarenga De Garcia
