Sehingga dapat disimpulkan bahwa pembelajaran dengan aspek makroskopis, mikroskopis, simbolik dapat menanamkan konsep secara utuh. Analysis of macroscopic, microscopic and symbolic levels of students in understanding electrochemistry AbstractThis research aims to find out the students’ comprehension from the macroscopic, microscopic, and symbolic aspects of the concept. The phenomenon of chemistry learning that is found almost focused on the macroscopic level in the form of formulas and numbers, while the level that often missed in some observation is microscopic and symbolic levels; such as diagramming and chemical reaction processes. One of the characteristics of chemistry tends to be abstract and complex, as the process of electrolysis reaction in which the particle movement can’t be observed so that misconceptions often occur in understanding chemical concepts. This study uses quasi-experimental methods with quantitative approach conducted by 40 semester students in the first semester of Pharmacy at the University of Muhammadiyah Prof. DR. Hamka. The research sample was taken by purposive random sampling with a questionnaire. Based on the result, the students’ comprehension of the electrochemistry concept have 72,75% good category in macroscopic level, 66,25% good category in microscopic level, and 70% good category in symbolic. So, it can be concluded that learning with macroscopic, microscopic, and symbolic could fulfill the concept perfectly.

Every teacher has experiences to identify and find out students who have misconceptions in their classrooms. Misconceptions that occur can differ between male and female students. The purpose of this study was to analyze the effect of gender on misconceptions in the lesson of the material classification and its changes. The survey-aiming method was used in this study. A total of 62 students from one of the state junior high schools in the city of Surakarta consisting of 34 male students and 28 female students were involved as the subjects in this study. Identification of misconceptions was conducted using the Two-tier multiple-choice diagnostic instrument that was equipped with the Certainty of Response Index method. The formulation of this study problem was: “How are the differences of misconceptions between male and female students in learning the material classification and its changes?” This study showed that female students tended to have misconceptions on the competency achievement indicator vis-a-vis explaining the understanding of elements, compounds and mixtures, while male students tended to have misconceptions on the competency achievement indicator pertinent to distinguishing elements, compounds, and mixtures. In general, female students had better conceptual knowledge than male students. The two-tier multiple-choice instrument could be used as an alternative instrument to identify misconceptions among students. The results of this study are expected to be a reference for educators to identify and resolve students’ misconceptions.
