In this paper, the parallel branch instruction is proposed which executes a branch instruction and the frequently used instruction simultaneously to improve the performance of Thumb-2 instruction set architecture. In the proposed approach, new 32-bit parallel branch instructions are introduced which combine 16-bit branch instruction with each of the frequently used 16-bit LOAD, ADD, MOV, STORE, and SUB instructions, respectively. To provide the encoding space of the new instructions, the register field in less frequently executed instructions is reduced, and the new instructions are encoded by using the saved bits. Experiments show that the proposed approach improves performance by an average of 8.0% when compared to the conventional approach.

This study aims to describe, explain, and understand the process of coteaching instruction in which two pre-service science teachers plan, perform, and reflect the instruction in a university lecture. Pre-service science teachers exchanged their perspectives on teaching, selected the learning model and the science content to teach, and prepared the teaching material together. They performed the coteaching using the lecture room effectively and exchanging the role of leading the instruction. The professor and other pre-service science teachers participated to the coteaching instruction directly or indirectly with the role of students or lesson critics, and shared the evaluation and reflection on the instruction. We discussed the meaning and implication of the coteaching instruction on the secondary education field, the science teacher education, and the science education.

This study tried to find the effect to cognitive structure upon the momentum effect. The previous studies showed that the momentum effect is influenced by students' cognitive levels and the abstractness of test items. The cognitive structure is examined by cognitive level and cognitive style. Cognitive levels and cognitive styles are determined by GALT and GEFT respectively. The research method used in this study is time series design. The period is 50 days. The period is divided into "pre-test", "intervention-test", "post-test". Pre-test period is 5 days and in this period class instruction does not exist Intervention-test period is 30 days and in this period class instruction exist Post-test period is 15 days and in this period class instruction does not exist. Field independent students showed longer momentum effect than field dependent students. Formal level students showed less ratio of decrease on post-test than nonformal level students. Momentum effects is not artifact but the essential characteristics of science study.

The purpose of this study is to explore the process of forming practical knowledge about library-based instruction of low-experienced teacher librarians. The study conducted interviews with six teacher librarians with less than three years of teaching experience. The analysis of the data collected focused on the teachers' self-knowledge and instructional knowledge, which are in the areas of practical knowledge. The results of the analysis of the study are as follows. First, the self-knowledge of teacher librarians was a teacher with leadership, who led students and teachers to reading education and information literacy instruction. Second, the self-knowledge of teacher librarians was most concretely formed in the process of pre-service teacher training, and the reflection on the teacher's image was taking place in the school field. Third, the knowledge of the instructional knowledge for library-based instruction was focused on library collaborative instruction, and various teaching methods were being learned and applied in school field. Fourth, there was a difference in the instructional knowledge of library-based instruction among teacher librarians. Through this study, it is suggested that the teacher training course and educational practicum activities should be changed by reflecting the contents of the actual school field, and the analysis of library-based instruction should be continued.

This study aims at identifying what effect ARCS model based instruction and cognitive style have on learning motivation and achievement in computer education. In order to accomplish this goal. 70 high school students were randomly allocated into the experiment group and the control group. And each group was divided into field-independent group and field-dependent group. The results were as follows. First, post test of learning motivation among four groups showed that mean differences were statistical significant. Especially 'ARCS model based instruction-field independent group got higher score than 'traditional instruction field dependent' group. Second, post test of learning achievement showed no significant mean difference among four group. The result of the pre and post test difference analysis showed that the change scores of means were significantly different.

The smart education recognized new educational paradigm is going to be introduced in earnest in the field from 2015. We develop the instructional design model for smart education to be able to provide a guide to design the instruction which has a speciality compared to current instruction. Furthermore, we did an expert assessment to recognize the validation and applicability of developed instructional design model and then apply this model to the field. As a result, we drew a positive conclusion for this instructional design model, which provides a base of systemic instructional design in smart education environment and focuses on expanding the ability of students living on 21st century. We expect that this study will be useful for teachers in the field who perform the smart education.

In present, an education paradigm of new info-age is consisting by using the Internet in education field, and as that practical use of internet in education is in increasing trend and various education method is showed. Also, as using the web by teacher and student, teacher can achieve efficiently instruction and student management and students can handle various kinds item about studies efficiently. But much of the existent systems were drived on instruction management, systems of student management are very few. Therefore, in this paper, we designed and implemented system that can efficiently manage instruction and student in web. Implemented system was designed by dividing teacher module and student module and various function for instruction management and student management were included in teacher module and in student module include various functions with related to as class, report and result record.

The purpose of this study was to develop a classification scheme for laboratory instruction, which could occupy a central and distinctive role in science education. For this study, literature on laboratory instruction types were analyzed. Utilizing several of these theoretical frameworks, a Classification Scheme for Laboratory Instruction (CSLI), which clearly represents various features of laboratory instruction, was created. The developed CSLI consisted of two descriptors: one is the procedure for laboratory instruction, and the other is a way of approach. The procedure is either designed by the students or provided for them from an external source. A dichotomy also exists for the approach taken toward the activity: deductive or inductive. Validity was established for the CSLI. In addition, laboratory instruction according to CSLI was divided into four types: verification, discovery, exploratory, and investigation. Although this study demonstrated only limited features of laboratory instruction due to the absence of a field test, it serves as a model for more comprehensive studies.

Land consolidation ratio for rice paddy fields reached to 64.7% as of 2008 in Korea, and this also accelerated automation of field machinery. Especially, research on autonomous tractors has been continuously conducted. Tillage is one of the labor-, energy-, and time-consuming field operations. Most important requirements for autonomous tractors would be travelling path planning and electronic system to control the tractor to follow the path. The instruction of computer was required to conduct the tillage operation in field with unmanned traveling tractor. This instruction was coincidently used in the control of the traveling path and the motion of tractor. The objectives of the study were 1) to characterize and model tillage operating sequence, turning pattern, and 2) to develop tillage path formation programs for autonomous tractor and evaluate the performance.

The field instruction is essential to professional social work education. It is important to identify what factors make students' performance improve. 207 social work students who completed the field practicum in their undergraduate course were studied to determine factors associated with performance. The mean score of supervision was 2.6 and of practice performance was 56.7. Especially the score of theory integrated supervision was lowest among 5 supervision factors. Intervention skills and case-management skills were lower than 3 other performance factors. The significant correlation found to exist between supervision and performance. The higher the students' perception of supervision, the higher the students rating of their performance. Contributing most to students' performance was students' perceptions of the extent of supervision, especially theory integrated supervision and agency-based supervision, the extent of discussion about learning contracts, the amount of supervision. And the personal factors like students' gender and supervisors' career duration as a supervisor were found to be another predictors. That is, female students could improve their performance more than male students and more experienced supervisors could not improve students' performance. The findings highlight the importance of supervision and learning contract. Structuring field learning experiences would be needed. The supportive and educative consults for the supervisors, especially for the experienced supervisors, and ongoing efforts to evaluate the field instruction were suggested.
