This paper reports the implementation of the “Flipped Classroom” in the class about chemistry to solve the problems of conventional classes. The implementation was carried out by active learning based on the knowledge gained by watching video materials as preparation for a lecture. The effects and the results of these practices are evaluated through questionnaire survey among the 161 students who participated in the “Flipped Classroom”. The percentage of positive evaluations in terms of satisfaction towards the classes increased after the “Flipped Classroom” is introduced. These results showed that the “Flipped Classroom” explored in this study has certain benefits, such as helping the students to increase their motivation to learn, to be accustomed to the learning, and to increase their learning time outside the class.

In this paper, we analyzed the survey and results on basic knowledge and elementary concepts of chemistry in an institute of technology and clarified the actual condition of students’ misconception. The difference of the mastery situation of the basic knowledge may prevent the right mastery of the basic knowledge by the accumulation of scientifically wrong recognition. Such scientifically wrong recognition is called “Naive Concept” , and it may become a hindrance in learning the advanced special subject. Therefore, we investigated the status of possession of simple concepts and acquisition of basic knowledge on chemistry by first and third-year students in an institute of technology. As a result, the following conclusions were obtained:(i) In both the first and third-year students, many incorrect answers suggesting the possession of naive concepts are found in the low percentage of correct answers to the survey questions. (ii) The percentage of correct answers in the third-year students is almost the same as in the first-year students. Furthermore, the tendency of errors in the free response columns is also similar. This indicates that the naive concepts of third-year students have not been corrected despite having taken chemistry in the first and second-year students.
