Reasons explaining the difficulties of understanding the concepts in the study of general chemistry in Burundi universities
This study was conducted to investigate reasons encountered in understanding concept in the study of general chemistry by undergraduate students in Burundi. Burundian University students were compared on (i) Teacher not leaving time for questions, (ii) no opportunity for group studies, (iii) syllabus wideness, and the using of a projector’ as a reason for concept difficulty in the study of general chemistry. A Difficult Concepts in General Chemistry Questionnaire (DCGCQ) was administered to 817 undergraduate students to collect quantitative data for the study while a Difficult Concepts in General Chemistry Interview Guide (DCGCIG) was the qualitative instrument used to elicit responses from the 8 randomly selected participants from 2 public universities and 2 private universities. Among 23 concepts investigated, the results showed that pH and octet rule are perceived as the most difficult concepts in the study of chemistry. On the basis of chi-square test, a significant difference was noticed for concepts such as Octet rule, Electronegativity, Quantum number, Chemical equilibration,
