In this study, a learning-teaching model enhancing the students to ask questions was developed and the influence of its application to the lesson of 'Chemical Change and Elements' of the 8th grade was investigated. This learning-teaching model was constructed initially by completing the work-sheet to activate student's question-asking, then by writing down their questions or uncertainties in the class, and finally with the feedback of student's question to the individual and to the class. Treatment and control groups (2 classes each) were selected from a girls' middle school in Seoul. and taught for 12 class hours during 4 weeks for this study. Before instruction, the test of attitudes toward science lessons and the test of adoption of scientific attitudes were administered, and the science scores of the previous course were obtained for the covariate. After instruction, the conception test. the achievement test, the test of attitudes toward science lessons, and the test of adoption of scientific attitudes were administered. The TOSRA (Test of Science-Related Attitudes) was used both for the test of attitudes toward science lessons and for the test of adoption of scientific attitudes. The study revealed that the treatment group showed significant differences from the control group in the scores of the conception test (p<.01) and of the achievement test (p<.05). But in attitudes toward science lessons and adoption of scientific attitudes. there were not significant differences between the two groups, even though the scores of the treatment group were a little higher than those of the control group. Educational implications of the effect of science teaching on the questioning activity of students are also discussed.

This study was attempted to understand the phenomenon in depth by exploring the special experiences of occupational health nurses who guided occupational health nursing practice education. Participants were eight occupational health nurses who had experience teaching occupational health nursing practice for more than a semester. Data collected as focus groups were analyzed by phenomenological methods. As a result of the analysis, the experience of student practice education of occupational health nurses was derived into four categories: 'Nursing student practice education started from their own experiences', 'Proceeding nursing student practice despite difficulties', 'Feel rewarding' and 'Presenting alternatives'. An understanding the experience of nursing student practice education by occupational health nurses can be used as a reference to improve or develop occupational health nursing practice curriculum, such as establishing practice regulations suitable for the characteristics of occupational health nursing practice subjects.

As calls for more attention toward social minority group increases in our society recently, in the field of mathematics education more attention toward an issue about mathematics underachievers is being amplified. Thus, the present study is to examine the effects of teaching method considering students' cognitive characteristics on mathematical underachievers' problem solving and mathematical disposition. For this study, 10 fifth graders identified as mathematical underachievers based on the results of the national level diagnosis assessment and school based assessment were voluntarily selected from an elementary school in Seoul. The results of this study found out the fact that students participating in this program improved in terms of an ability both to solve problems in various ways and to explain an process of problem solving using spoken or written language and drawings. In addition, learning environment respecting students' own mathematical ideas seems to positively influence students' attitudes toward mathematics learning and mathematical dispositions. Furthermore, this study pointed out that mathematical underachievers tend to have difficulty in expressing their own mathematical thinking by reason of linguistic limitation. Finally, the findings of this study imply that for effective teaching of mathematics underachievers, these students' own informal experience and knowledge about mathematics as well as their characteristics regarding learning difficulties should be strongly considered.
