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,
期刊介绍：
The purpose of this journal is to provide a medium of exchange for scientists engaged in applied sciences (physics, mathematical physics, natural, and technological sciences) where there exists a non-trivial interplay between mathematics, mathematical modelling of real systems and mathematical and computer methods oriented towards the qualitative and quantitative analysis of real physical systems.
The principal areas of interest of this journal are the following:
1.Mathematical modelling of systems in applied sciences;
2.Mathematical methods for the qualitative and quantitative analysis of models of mathematical physics and technological sciences;
3.Numerical and computer treatment of mathematical models or real systems.
Special attention will be paid to the analysis of nonlinearities and stochastic aspects.
Within the above limitation, scientists in all fields which employ mathematics are encouraged to submit research and review papers to the journal. Both theoretical and applied papers will be considered for publication. High quality, novelty of the content and potential for the applications to modern problems in applied sciences and technology will be the guidelines for the selection of papers to be published in the journal. This journal publishes only articles with original and innovative contents.
Book reviews, announcements and tutorial articles will be featured occasionally.
