Abstract

The problem of student’s misconceptions of stoichiometry is still happening even though there have been so many studies done for identify misconception experienced by students. It is because most of those research is only focused on revealing student’saomisconceptions. The purpose ofathisastudyais to identifyatheatendency ofomisconceptions experienced by studentsuanduexamineatheaappropriate learning strategies that can be applied to avoid those misconceptions. Comparative study is performed to determine misconceptions appeared in the identification process through various diagnostic instruments, namely two-tier test, three-tier test and certainty of response index. Thearesultiofothispstudy showsithatimost of misconceptions appeared because rstudents are too focused on the algorithmic aspects and put aside the conceptual aspects in solving stoichiometric problems. It is caused by the instruction process which emphasizes the success of using formulas to solve numeric problems so students ignore understanding of related concepts. The use of chemical representation visualization through student-generated sub-micro diagrams is considered capable of being a link between macroscopic and symbolic phenomena so as to enhance students’s understanding of concepts related to stoichiometry.

Abstract

The ability to solve problems is one of the ability to learn and innovate in the face of 21st century chemistry learning but the problem is that the ability to study chemistry is still low. Learning is still teacher-centered and there is a lack of student involvement, so one model is needed to improve it, the flipped classroom model. The purpose of this study was to determine the ability of problem solving through the flipped classroom model on the reaction rate material. The research method is descriptive quantitative in 34 students of MIPA 2 XI grade in one of the state high schools in Tangerang Regency. The instrument used was 16 essay test questions that were assessed using the problem solving scoring rubric according to Schoen and Oehmke on a scale of 1-10 then the scores were interpreted based on criteria according to Riduwan. The results of this study indicate that the ability to solve problems through the flipped classroom model has very good criteria with a percentage of 81.3. These results students are expected to compete and meet educational competence in the 21st century.
