  • The purpose this research was to develop the practicum-affiliated coursework for pre-service chemistry teachers to enhance their instructional professionalism. The researchers developed the syllabus and the materials of the practicum-affiliated coursework and opened the class 'Practice of Chemistry Lesson' for the pre-service chemistry teachers who were expected to participate in the practicum. Semi-constructed individual interviews revealed that pre-service chemistry teachers thought the developed coursework, which linked science education theory and practice, helped them to develop educational connoisseurship about good science class and to be prepared practically to the practicum, and as the result, they could enhance their teaching ability. The result identified that the reconstruction of the practicum experience through the process of 5 steps of the curriculum could develop the instructional professionalism of pre-service chemistry teachers.

  • The purpose of this study was to analyze chemistry textbooks and teachers' guidebooks from the perspective of 'Ignorance', one of the important features of model. This is because the emphasis is on developing modeling capabilities for students in the 2015 Revised Curriculum. For this, Arrhenius model and Brønsted-Lowry model were selected as acid and base models in neutralization reaction which are important contents in chemistry curriculum. The analysis criteria of this study were extracted by analyzing previous studies and four general chemistry textbooks dealing with 'Ignorance' related to acid and base neutralization reaction. Based on the analysis criteria, we analyzed nine chemistry I textbooks and teacher's guides and six chemistry II textbooks and teacher's guides of the 2015 revised curriculum. In addition, we analyzed contents of four chemistry I textbooks and teacher's guides and three chemistry II textbooks and teacher's guides in the 2009 revised curriculum for comparison according to revised curriculums. We analyzed the contents related to the concept of 'neutralization reaction', 'neutrality', 'quantitative relation of neutralization reaction', 'degree of ionization', and 'ionization constant'. Based on the results of this study, we proposed a way to present 'Ignorance' of the models in teachers' guidebooks that chemistry teachers can understand 'Ignorance' of model and teach modeling capabilities for students.

  • The purpose of this study is to compare the contents of chemistry textbooks developed according to the 2015 revised curriculum with the contents of the 2009 revised curriculum to research the change in "the development and use of models". To do this, we analyzed 8 kinds of Chemistry I textbooks and 6 kinds of Chemistry II textbooks from the 2015 revised curriculum and compared them with 4 kinds of Chemistry I textbooks and 4 kinds of Chemistry II textbooks from the 2009 revised curriculum. The scope of the analysis was the explanations of the textbooks related to aqueous electrolysis experiments. In order to compare the contents regarding electrolytes when the same experiments are interpreted with different models, we analyzed contents of 4 kinds of middle school science textbooks from the 2015 revised curriculum and 9 kinds of middle school science textbooks from the 2009 revised curriculum. As a result of the analysis, the same experiment was explained by different models according to the grade level and unit, and all explanations were limited to a single model. Also, the tendency to limit the kinds of electrolytes for controlled experimental results is more pronounced in the 2015 revised curriculum than in the 2009 revised curriculum. From this results, we suggest that efforts are needed to reflect the "development and use of models" in chemistry textbooks developed according to the 2015 revised curriculum.

  • Characteristics of chemistry education during the enlightenment period in Korea are examined by analyzing chemistry textbooks used in the period. Specifically, the analysis is made from the aspects of science, students and teachers. As a result it is found that; first, scientific knowledge itself is emphasized, contrary to those described in the curriculum of chemistry used in the period, and it consists of introduction, non-metals, metals and organic chemistry in chemistry textbook, second, the level of chemistry is similar with that in present high schools, and its technical constitution might have been difficult for a student to study with an experiment, third, terminology lacks consistency and some textbooks include contents of other subject. It is therefore believed that the chemistry textbooks of the enlightenment period is scientifically incomplete and would not have been easy for the teachers to use them to teach the students. In addition, considering the students as a beginner of modern sciences, study level could have been too difficult for them to follow. In conclusion, it appears that chemistry education during the enlightenment period in Korea was not so successful.

  • This study introduces lessons learned from investigation and analysis of major domestic and overseas cases of marine chemical incidents involving hazardous and noxious substances (HNS) during maritime transportation by chemical tankers carrying petrochemical products in bulk. The study then suggests plans to improve domestic marine HNS training curricula based on these lessons. Lessons learned from six incident cases are classified into the following six categories: 1) incident-related information, 2) safety, 3) pollution, 4) response, 5) salvage and 6) others. Based on these six categories, it is suggested that the curriculum provided by the Marine Environment Research & Training Institute for marine pollution prevention managers aboard noxious liquid substance carriers should be changed from the existing two-day training of eight subjects (16 h) to a three-day training of sixteen subjects (24 h). In addition, it is proposed that the marine chemical incident response course of the Korea Coast Guard Academy should be changed from the existing five-day training of fifteen subjects (35 h) to a six-day training of thirty-two subjects (48 h). These results are expected to contribute to sharing experiences and lessons learned about response to marine chemical incidents and to be used as basic data for improving the education and training courses for response personnel in preparedness for marine HNS incidents.

  • The purpose of this study is to analyze the chemistry curriculum between Korea and New Zealand. Both countries state that they want to cultivate their key competencies through the curriculum, and Korea' key competencies are similar to New Zealand'. Also, we find a strong correlation between key competencies of Korea science and achievement aims of the nature of science in New Zealand. Specially, the achievement standards that cultivate the key competencies are presented separately in New Zealand curriculum and NCEA, and confirms the achievement level through internal evaluation. By comparison, the curriculum content for chemistry is a good fit because of the overlap in the content. The Chemistry I is in the 7th level of New Zealand curriculum and the Chemistry II is in the 7th and 8th levels of New Zealand. However, there are some differences in hydrocarbon, ideal gas equation, colligative property and understanding of spectroscopic data.

  • This study analyzed the questions posted on the chemistry Q&A board by students and teachers in a chemistry education homepage, in order to understand the difficulties in learning and teaching chemistry. The different tendencies were found in the contents and the motivations of questions by students and teachers. In Chemistry I, students raised many questions in the 'Water' unit, while teachers raised many ones in the 'Chemical compound in our life' unit. In Chemistry II, students asked many questions in the 'Gas, liquid, solid' unit, while teachers did in 'Chemical reaction and energy' unit. Students' motivations of questioning were 'Explanation of unclear concept', and 'Problem solving', while teachers' motivations were 'Searching information', and 'Question in experiment'. The Q&A board provided a field in exchanging informations needed in learning and teaching chemistry. Educational implications were discussed on the use of Q&A board in chemistry education.
