  • The purpose of this study was to contrive the specific teaching plans based on the frame of 2007 revised science curriculum for applying open-inquiry lesson in real education situation and to research the effects of open-inquiry lesson on the student's science-related attitude, science process skill, and to investigate instructing teachers' cognition about open-inquiry. For this study, two fifth grade classes were chosen, one class was the experimental group, who were taught by open-inquiry based lesson, and another was the comparative group, who were taught by traditional method based lesson. The findings of this study were as follows: After open-inquiry lesson, the experimental group students came to enjoy open-inquiry learning and had the positive thought about it. After open-inquiry lesson, the experimental group marked higher mean score than the comparative group in science-related attitude's field but didn't showed the meaningful difference. On the other hand, in science process skill's field, the experimental group showed the significant higher improvement than the comparative one, especially in the subordinate area of basic science process skill. Finally, teachers who instructed students open-inquiry lesson thought open-inquiry lesson is the self-directed problem solving learning which raise the student's science process skill and interest. And the teachers thought the obstacles to instruct open-inquiry lesson are the lack of the student's cognition about open-inquiry and the insufficient circumstance for open-inquiry lesson. Therefore the teachers argued that the prerequisite for settling open-inquiry lesson successfully is to develope open-inquiry lesson curricula and teaching materials.

  • Purpose - Recently on-the-job training (OJT) has become the most preferred training and development method with the emergence of the concept that workplace is the best place where learning take place. But many researchers argue that OJT is not helpful for the performance of organization because OJT is not systematic and mostly depend on quality of trainer. Since Jacobs & McGriffin introduced S-OJT (structured OJT), there has been plenty of researches. But most of the researches have focused mainly on employee's attitude and organizational performance caused by S-OJT and neglected a holistic approach of S-OJT as a system. S-OJT need to be analyzed comprehensively to understand training performance because S-OJT is operated as a system consist of input, process, and organizational context. Although S-OJT may create unintended consequences, there were few researches to explore them. Thus, the purpose of this study is to identify the critical success factors for S-OJT and to find unintended consequences of it. Research design, data and methodology - We conducted a case study on M business unit of A company which developed and has been implementing S-OJT program for years. We designed and prepared the process, collected and analyzed data for the study. We set the theoretical framework to analyze the case after reviewing theories and previous studies on S-OJT. We collected and analyzed internal reports and interview results of the employees of the M business unit. We tried to collect as many information as possible to secure the validity of the research results. Results - The critical success factors identified in the study are as follow. First, it is important to select and train proper trainers for S-OJT. Second, it is needed to develop structured training module. Third, organization have to use effective communication system like on-line community. Forth, trainer should have proper skills for training such as facilitating skill, coaching skill, and delivering skill etc. Fifth, proper learning place is needed. Sixth, organizational support is important especially, immediate supervisor support and concern is critical. Eleventh, it is needed to consider situational contexts. Among them, overload to the trainer will affect the effectiveness of S-OJT. In this study, we found an additional unintended consequence. "To teach is the best way to learn." Experience as a trainer give employee an opportunity to organize one's knowledge and skill and to attain facilitation skill, coaching skill, and relation skill. Thus, organization may use S-OJT to train the potential talent. Conclusions - Many organizations introduced S-OJT to train the newcomers because S-OJT drew attention as an important tool to develop employees. Following this trend, there has been increasing number of researches to find the results of S-OJT and identify the determinants of S-OJT success. However, most of the researches concentrated on finding effects of some factors neglecting holistic approach. This study tried to identify critical success factors affecting effectiveness of S-OJT by using case study and find additional unintended consequence. The results of the study will be useful for organizations which have a plan to adopt S-OJT.

  • The purpose of this study is to inquire the properties and relationship of attitudes toward science and process skills of preservice elementary teachers. Two instruments were used to collect the data, SAS(Science Attitude Scales) for checking up attitude toward science and TIPS II(Test of Integrated Process Skill II) for inspecting science process skills. Three main results were revealed. First, preservice elementary teachers' the attitude toward science and science process skills could not show the significant differences by gender. This result is differ from the results of preceding researches which had set up the students of elementary, middle and high school as objects. Second, the properties of preservice elementary teachers' the attitude toward science and science process skills according to the course in high school were also differ from those of preceding researches having students as objects. The preservice elementary teachers who got the literary courses in high school were more confident in science learning and perform that those who have the academic background of science courses in high school. In addition, although they showed better abilities in two sub-scales of science process skills, the preservice teachers with science course didn't show the better science process skills than those who had taken the literary course in total score of science process skill test. Third, there was a significant relationship between attitude toward science and science process skills of preservice elementary teachers but just one sub-scale was related with science process skills. According to these results, it can be said that the preceding results with students as objects can not be applied to and preservice elementary teachers should be guided by the methods which are considering their special properties.

  • The purpose of this study was to develop teaching modules related to Earth Science courses in order to enhance scientific inquiry skills of middle school students. A 'process skill-centered' module was developed to induce scientific process skills, while students explore specific scientific context. A module consists of several activities, and each activity focuses on a specific science process skill. Modules were designed such that the skills would improve depending on the completion of the module. To evaluate the effectiveness, field workshops for middle school science teachers were done twice. Science teachers, who were participants of the workshop, commented that the activities in each module were suited to enhance students' interest in science. They noted that scientific inquiry skills would be developed from each activity. Students responded that the activities in the modules were interesting, and it was a good experience to do them by themselves. Students were the focal point in class, not teachers. This enabled teachers to evaluated each student's achievement level, and provide a proper feedback. Hence, applying these modules in classes should enhance the students' scientific inquiry skills.

  • This study investigated the influences of metacognitive learning strategies upon 6th-graders' achievement, science process skill, use of cognitive strategies, use of metacognitive strategies, self-efficacy, intrinsic value, attitude toward science class, and scientific attitude. The metacognitive learning strategies were developed on the basis of previous results and modified in a pilot study. Before the instructions, a pretest of motivation was administered, and used as a blocking variable. The score of previous achievement test was used as covariates for achievement and science process skill. Tests of use of cognitive strategies, use of metacognitive strategies, self-efficacy, intrinsic value, attitude toward science class, and scientific attitude were also administered, and their scores were used as covariates. After the instructions, a researcher-made achievement test, the Middle Grades Integrated Science Process Skills Test, and post-tests of above variables were administrated. Two-way ANCOVA results revealed that the scores of the treatment group were significantly higher than those of the control group for all tests except for science process skill. No interactions between the treatment and the level of the previous motivation were found. Educational implications are discussed.
