The purpose of this study was to investigate the effect of mental practice about functional performance of affected limb to unilateral neglect and ADL(Activities of Daily Living) in person with stroke. A single subject experimental research with ABA design was employed in this study. The experiment formed 18 sessions in total: 5 sessions for baseline, 10 sessions for mental practice treatment, and 3 sessions for the second baseline. Mental practice was composed of performing 3 functional activities(dressing clothes, make-up with materials and arrangement, folding clothes). It took 5 minutes at once and 15 minutes in total daily. The unilateral neglect was measured by reading test, writing test, and Baking Tray Task. ADL was assessed by COPM. The results indicated that unilateral neglect test scores were all reduced, and the score of COPM was clinically significant. Mental practice for performing of functional activities was effective method to reduce unilateral neglect and improve ADL in person with stroke.

This study investigated the types and frequencies of student-student questioning (SSQ) in a small group activities, 5 in one group or 2 in one group, during school experiments. Five girls of seventh grade were observed during school experiments and interviewed afterward. Between students, information-type questions were asked more frequently than thought-type questions. Most of the information-type questions were procedural ones and most of the thought-type questions were comprehension ones. However, thought-type questions did not make further discussion in the activities. The rate of answers in the case of 2 in one group was higher than that of 5 in one group. Moreover, the similar tendency was found when we investigated the rate of helpful question-answers. In a pair, lower achiever usually asked questions, not answered as much as in 5 in one group, and higher achiever answered. The frequency of SSQ in a pair was relatively low when there was a big difference of science achievements between pair members. In conclusion, information-type questions were asked more frequently than thought-type questions during school experiments and the rate of helpful question-answers was higher when group members was fewer.

The purpose of this study is to investigate preservice earth science teachers' mental models through applications of Coriolis force experiment apparatus. After the root of preconception was examined by face to face interviews based on the questionnaire, five preservice earth science teachers were finally selected for this study. The mental models about concept of Coriolis force was classified into naive mental model, static unstable mental model, dynamic unstable mental model, and scientific mental model through the result of individual interviews and their drawings. According to the mental model analysis about Coriolis' force conception, students C and M showed naive mental model about concept of Coriolis force before experiment. After the experiment, student M's model changed to static unstable mental model. Student C's model improved to dynamic unstable mental model. In adiition, students D and O's model improved from static unstable mental model to dynamic unstable mental model. In the case of student B, the dynamic unstable mental model was maintained after the experiment, however, student B's preconception changed to scientific concept. It turned out that a change occurred from low mental model level to integrated mental model after the application of the developed Coriolis' force experiment apparatus. According to the results, national curriculum is similar to static unstable mental model and the result of developed Coriolis' force experiment apparatus is similar to dynamic unstable mental model. It is suggested that it become the theoretical foundation to develop more comfortable and advanced Coriolis force experiment apparatus by improving the experiment apparatus.

The purpose of this study was to develop the elementary school science instructional material for nurturing students' creativity and to analyze the effects of this material on the changes of students' creativity. This material was composed of student's worksheet and a teacher's guidebook, in which are relevant to the elements of creativity and creative activities that can be applied to elementary science curriculum of 5th and 6th grades. Student's worksheets include various creative activities: imagination, guided imagery, experimental activity, mind mapping as wrap-up, and 'let's think' as an extended activity, game, puzzle, making a cartoon, to be, role playing, and so on. These materials were applied to 5th grade science class, 156 students. They were divided into two groups: the treatment group to which developed material was applied and the control group which was a traditional lecture-centered class. After this material had been applied for 3 months, students of both groups took a test of creativity. Interviews and observation were also carried out with three level groups (higher, medium and lower level) which were divided within the treatment group based on their creativity score. The results of this study were as follows: The treatment group showed higher score on creativity than that of control group(p<0.01). In the result of interviews and observation, the students of the higher and the medium level accomplished their tasks by themselves better than those on lower level.All of them took an interest in visual activity. In a wrapping-up step, the higher level students made mind map more systematically and the medium students improved as time goes on, but low level students feel constrained. In totally, they used various expression methods and were interested in making drawings and cartoons creatively.
