Investigations into how the status of prior learning on the textbook of science were conducted, and the effects of prior learning on students' attitudes towards science class were carried out. The investigations for the status of prior learning were performed with a number of students who experienced prior learning, (self-directed and unself-directed prior learning), a selfless intention as the starting motive for prior learning, the problem solving strategies used by students in prior learning, and the important factor that influenced prior learning. The effects of prior learning on student attitude towards science class were also examined with respect to four categories, including confidence, interest, learning intention, and value (effect). The effects of prior learning on the four categories were analyzed on the basis of the students' level of scientific achievement, the types of prior learning, the starting motive for prior learning, and the extent of the students' understanding of the content on prior learning. The analytical results for the effects of prior learning on students' attitudes towards science class showed that the mean values of confidence, learning intention, and value among the students in the self-directed prior learning group were higher than those of the students in the unself-directed prior learning group. These findings are the result of positive recognition, such as the possibility that the students experienced with self-directed prior learning can do, the induction of an inherent motive based on their level of achievement in science class, and the operant learning of strategies for solving problems in science class. Meanwhile, by the effects of having a teacher lead the science class and the consensus formed between friends, the mean level of interest was higher in the unself-directed prior learning than in the self-directed prior learning.

In this study, the verbal interactions occurred during the CASE(Cognitive Acceleration through Science Education) activities in the middle school science class has been analyzed regarding with students cognitive level. The subjects were 24 students of 6 groups in a middle school in Korea. Verbal interactions within group discussions during CASE activities were audio-taped, transcribed, and analyzed. Also, classroom observation and interview with students were carried out. The results showed that the student with higher cognitive level tended to be a group leader. They had strong influences on the group discussions in each step of problem solving. Also, the higher cognitive level students were more active in metacognitive discussion and more often used scientific terms. When their group met difficulties in each stage of problem solving, such as perception of problem and designing experiment, the higher cognitive level students suggested some ideas to help their peers and gave them an explanation of how they worked. Low cognitive level students had difficulties in perception and solving the problem as compared with high cognitive students. It was common during activities for the low cognitive level students to fail to identify variables and to distinguish between dependent variables and independent variables. They failed to hold a number of variables at once. However, the metacognitive questions from their peers or teacher were helpful for them to construct the concept of controlling variables. If there is no student who has a high level of thinking in a group, it was necessary to intervene for teacher. A well judged questions from teacher created the cognitive conflict which causes the students to reconstruct their strategy for problem solving and reinforce the control of variables reasoning pattern. From the above results, it is concluded that students' cognitive levels are much related to the verbal interaction patterns. This suggests that teacher should consider individual student's cognitive level in organizing groups and intervene to facilitate the environment for metacognitive interaction.

In order to analyze the educational effect of learning mentoring conducted for 4 weeks by the Korea Educational Broadcasting System(EBS) for elementary school students, the changes in self-directed learning skills and emotional stability were analyzed through pre-test and post-test for 27 students who participated in the EBS learning mentoring. As a result, it was found that students' self-directed learning ability and emotional stability were both improved. In addition, the students showed high satisfaction with the mentor who guided their learning and taught them. Therefore, in order to reduce the learning gap of underprivileged students in the distance learning situation, the EBS learning mentoring project should be continuously promoted, and the mentoring period and the number of students and teachers participating in mentoring should be significantly increased.

This study investigated verbal behaviors and interactions in the processes of making written test items using paired think aloud problem solving for pre-service secondary chemistry teachers. The processes of making written test items using paired think-aloud problem solving in four small groups consisting of two pre-service chemistry teachers were recorded and transcribed. The analysis of the results revealed that 'item making' for ten subcategories for solver's verbal behaviors were most frequently exhibited regardless of 'integration' among the components of pedagogical content knowledge (PCK). The solver's 'provide', 'modify', 'require agreement', 'ask', 'agree', and 'justify' were also frequently exhibited although fewer than 'item making'. Especially, the solver's 'ask' was more frequently used in 'non-integration', whereas 'justify' was more frequently used in 'integration'. In listener's verbal behaviors consisted of eight subcategories, 'point out', 'ask', and 'agree' were frequently exhibited regardless of 'integration'. Listener's 'ask' and 'agree' were exhibited more in 'non-integration', whereas 'point out' was exhibited more in 'integration'. Many verbal interactions were analyzed to be in 'symmetrical type' more than 'solver-dominant type' or 'listener-dominant type'. 'Symmetrical type' was also more frequently exhibited in 'integration', whereas 'solver-dominant type' was more frequently exhibited in 'non-integration'. There were little differences between 'integration' and 'non-integration' in 'listener-dominant type'. In 23 subcategories of 'symmetrical type', 'ask-provide' and 'point out-justify' were most frequently found. Especially, 'ask-provide' was more frequently found in 'non-integration', whereas 'point out-justify' was more frequently found in 'integration'. 'Point out-modify' was the most frequent in 4 subcategories of 'listener-dominant type', while 'item making-agree' in three subcategories of 'solver-dominant type' regardless of 'integration'. However, only a little of other subcategories of the three types were found.

The purpose of this study is to consider the implications of science experiment in class and to seek a direction for its improvement. For this purpose, Science textbooks, teachers' cognitions, and classroom activities have been analyzed to find out how many and what kind of levels of inquiry elements are included in those. In this study, 22 teachers have participated in the questionnaire to investigate their perception about experiment class, and the two instruction cases in two classes of 9th grade have also been analyzed. Results show that most of the textbooks have included questioning, evidence collecting, explanation of phenomena, and connection with existing scientific knowledge. But the elements of communication and justification have been few. Most levels of the inquiry are teacher-led. Although the teachers thought communication and justification are important, their classroom activities does not coalesce with their thoughts. The students mostly spend their time with connecting evidence, they hardly explain the phenomenon based on the proofs as the results of experiment, and the activities of connection with the existing scientific knowledge, and communication and justification.

Problem-based Learning (PBL) has been known as an effective strategy for dealing with various aspects of education such as the enhancement of students' motivation, interest in subjects, academic achievement, and cooperative abilities. However, PBL has not been widely implemented in secondary schools. The purpose of this study is to investigate secondary school teachers' perception of problem-based learning and their way of applying it. Data was collected through semi-structured interviews with nine secondary school teachers. Five of them had experience in implementing PBL, while four of them had interest in using PBL but had not yet had the experience. Different concepts were extracted and categorized. Nvivo 2.0 was used for analysis. The results were as follows: Changes in student attitude toward class, improvement on cooperation with others, self-regulated learning skills, and satisfaction from students' positive comments on PBL enabled teachers to become more enthusiastic and positive toward PBL. The stress of developing proper problems and the enormous amounts of time and efforts required in using PBL were shown as barriers for teachers in implementing PBL. However, some negative perspectives about PBL changed into positive after teachers experience PBL. By examining each teacher's way of implementing PBL, several teaching strategies suitable to their school systems were suggested.

This study carried a survey to investigate teacher's cognition on preference and actuality about science laboratory and class environment targeting 262 science teachers. The results of this study are as follow: First, the actuality cognition of science teachers on science laboratory and class environment was lower than preference (p<.05). Second, there were no differences between preference and actuality regardless of gender (p<.05). However, the cognition on all of subordinates of preference appeared higher in females than males (p<.05). Third, at all levels of schools, preference is higher than actuality for science laboratory and teaching environment (p<.05). In case of preference, all of the subordinates indicated the difference between elementary and high school teachers (p<.05). On the other hand, in actuality there was a difference between elementary and middle school teachers in 'science laboratory facilities condition' domain only (p<.05). Fourth, the preference was higher than actuality in all school locations (p<.05). And in case of preference, there was no difference in all subordinates regardless of school sites. Whereas the cognition of small-medium city teachers was lower than metropolitan in actuality on the three domains of 'science laboratory facilities condition,' 'teaching condition and service support,' and 'staff policy and practice' (p<.05). As a result, this study informs that upgrading is necessary to achieve inquiry activity in science class in overall teaching environment including science classroom and laboratory.
