Despite its considerable publicity, the studies focused on the FC in primary education are deficient. The aim of this research is to determine efficiency and students{\textquoteright} involvement in the flipped Biology classroom in primary school, compared to the conventional classroom (CC) approach. Educational efficiency and students{\textquoteright} involvement are measured by combining the values of the students{\textquoteright} performance and mental effort on the test. Each task in the test was followed by the 5-point Likert scale for evaluation of invested mental effort. The total sample of this research included 112 students, aged from 12 to 13. The results show that the FC approach contributes to the reduction of the students{\textquoteright} mental effort and an increase in the students{\textquoteright} performance. On the basis of calculated efficiency and students{\textquoteright} involvement of applied teaching approaches, it was concluded that the FC represents a feasible and efficient approach to Biology primary education.}, keywords = {biology education, educational efficiency, flipped classroom, mental effort, primary school, students{\textquoteright} involvement}, issn = {1648-3898}, doi = {https://doi.org/10.33225/jbse/18.17.162}, url = {http://oaji.net/articles/2017/987-1519060434.pdf}, author = {Vera S. {\v Z}upanec and Branka N.
