Abstract

The ability to solve problems by Stoichiometric method is an inseparable process of chemistry and the correct understanding of this topic is of great importance. In the present study, the challenges of Learning stoichiometry among a number of female students of the 11th year, experimental field, were investigated in Tehran. In this research, 55 students were evaluated using questionnaires. Sampling was done randomly. The data and information obtained from the questionnaires were analyzed by descriptive-analytical method. The obtained results showed that a large number of students tend to use alternative methods instead of Stoichiometric solution method. According to the analysis, many students do not have a correct understanding of stoichiometry and consider it a complicated method. In fact, they believe that stoichiometry does not have a specific formula or organized path and therefore cannot be preserved. Perhaps the root of this way of thinking should be seen in the teacher's presentation of different solutions in every stoichiometry problem and the student's lack of correct understanding of the basic concepts of chemistry. Therefore, it is suggested that chemistry teachers give students an opportunity to review the basic concepts before presenting the problem, and in solving the problem, instead of presenting the solution, ask the students to complete the solution path with their own knowledge. In this way, instead of memorizing steps by students, their cognitive skills are used, in addition, solving the problem of misconceptions about stoichiometry can be accurately identified and corrected by students themselves, and their Learning process is facilitated.
