"Due to their abstract nature, the mole concept\r\nand solution concentration are difficult for students to\r\nunderstand and apply to stoichiometric calculations. This\r\nstudy was designed to investigate students’ perceptions and\r\ndifficulties in solving problems related to the mole concept\r\nand solution concentration. Thirty-eight students (18-19\r\nyears old) who were pursuing science related programmes\r\nfrom a private university college in Malaysia participated\r\nin the study. Students were asked to answer twenty-five\r\nopen-ended questions on the mole concept and solution\r\nconcentration. Analysis of students’ responses revealed\r\nthat they were not able to connect the mole concept with\r\nmass and number of particles. Students were also grappling\r\nto answer problems regarding concentration and dilution.\r\nThis study suggests that it is important to determine\r\nwhether students’ difficulties to master the concepts are\r\ndue to lack of knowledge or the presence of alternative\r\nframeworks so that so that pedagogical instruction can be\r\nmodified. This study was part of a larger research project\r\nwhere students’ responses on this open-ended test will be\r\nused to get a greater generalizability in order to construct\r\nthe alternatives to the four-tier multiple choice (4TMC)\r\ninstrument to identify students’ alternative frameworks on\r\nthese concepts.
