In this paper I will look into achievement standards which show gender difference. This work is based on the average of percentage of correct answer about items taken in National Assessment of Educational Achievement (2010~2014) at each male and female student of middle school. Achievement standard becomes the basic unit when teachers make study plans as the smallest unit that composes the curriculum. Study plans are expressed concretely according to lesson time numbers, and then lesson time numbers are determined by achievement standards. Therefore, objective informations about gender difference appearing in achievement standards will play an important role in embodiment of programs to obliterate gender difference when teachers make study plans. Also This research is expected to play a role as an indicator in studying on gender difference in mathematics education.

It is crucial to understand the characteristics of learner questioning due to the effects it has on learning. This study focuses on the effects of middle school students questioning on their academic achievement in an online inquiry learning environment. A survey of 827 middle school students was conducted; the students took part in an online math and science program offered by a center for the gifted. Throughout the survey, learner questioning was analyzed, and its correlation with academic achievement was investigated. An analysis was based on questioning categories of a low- and high-level questions from previous studies. Through the survey, it was found that the number of learner questions asked in the online environment was small, but the number of low- and high-level questions were almost equal. Secondly, the higher the academic achievement level of the student, the higher the possibility they would ask either low- or high-level questions. Lastly the group of students in both low- and high-levels of questioning earned the highest average scores on formative evaluations and inquiry tasks. This indicates that regardless of the level of questions, the act of questioning itself is highly related to the academic achievement. However, in the case of advanced learning projects, the quality of questioning and high-level questioning affected the academic achievement of students. Based on these results, implications for the encouragement of learner questioning and support for asking high-level question are suggested.

This paper compares and analyzes mathematics teachers' understanding of students' mathematical comprehension after experiences with the Cognitively Guided Instruction (CGI) or the Development of Mathematical Ideas (DMI) teaching strategies. This report sheds light on current issues confronted by the educational system in the context of mathematics teaching and learning. In particular, the declining rate of mathematical literacy among adolescents is discussed. Moreover, examples of CGI and DMI teaching strategies are presented to focus on the impact of these teaching styles on student-centered instruction, teachers' belief, and students' mathematical achievement, conceptual understanding and word problem solving skills. Hence, with a gradual enhancement of reformed ways of teaching mathematics in schools and the reported increase in student achievement as a result of professional development with new teaching strategies, teacher professional development programs that emphasize teachers' understanding of students' mathematical comprehension is needed rather than the currently dominant traditional pedagogy of direct instruction with a focus on teaching problem solving strategies.

Computer based instruction in the elementary science curriculum will be played an important role through the fifth curriculum reform from the 1989 school year. This is essential for the science instruction because the strategies on the problem-solvings and inquiry approaches can be utilized for the science classroom. Computer education can be thought as the education about the computer and the education using the computer. Of them the education using the computer means the computer assisted instruction(CAI) what is called all the possible activities using the computer in the classroom. Student achievement as the result of CAI depends on the learning activities of students and the instructional techniques and strategies of teachers using the computer. However, computer based education to enhance the student achievement is pointed out the lacks of the standardized Korean alphabet code and the compatibility of qualified software. These problems will be relieved according to the coding for the Korean alphabet of SUPER PILOT program language.

This research has three purposes: The first purpose is to verify whether SGRs(Student-Generated Rubrics) are effective for learner achievement in higher education or not. The second one is to analyze the agreements between an instructor's evaluations and peer group assessments with SGRs in real classroom situation. The final purpose is to propose the possibility of students' more objective self-evaluation with the use of SGRs. It appears that rubrics are effective tools to improve learner achievement in adult education and to promote the agreement between the instructor's and peer's evaluations, even though learners do not develop SGRs. In addition, this research has demonstrated that most students are not very accurate self-assessors, and they often overestimate themselves. This study can be helpful for novice instructors, especially for those who try to assess their students more fairly, to develop the SGRs as an evaluation tool appropriate for their own situation, and to give more reliable feedback to students.

In this paper, availabilities of student-evaluations of team activities in the computer science basic classes were analysed. For the purpose, correlation analysis was conducted to investigate the relationships among peer-evaluation, self-evaluation, and academic achievement, and it was found that there was a statistically significant positive correlation among them. Moreover, the gap between peer-evaluation scores and self-evaluation scores was analyzed. When a one-sample t-test was performed, it was found that the gap was very significant. However, the size of the gap was not different between the two classes. That is, regardless of grade level, the students' self-evaluation scores tended to be on average higher than the evaluation scores received from peers. Finally, when analyzing the relationship between the gap in peer-evaluation and self-evaluation scores and academic achievement, there was no significant correlation between the gap in scores and academic achievement. In other words, there was no difference in the tendency of evaluation for students with high or low academic achievement. The results of the analysis shows the availability of student-evaluations of team activities in the evaluation of team-based instruction. The high correlation between self-evaluation and peer-evaluation indicates the objectivity of student-evaluation. Although it is clear that the self-evaluation score is higher on average than the score received from peers, it is more useful in terms of objectivity because it does not vary according to grade, subject, or academic achievement.

Objectives: This study aimed to investigate the effect of clinical clerkship-associated achievements, such as performance of procedures at the student clinic, observation, and attitude towards a clerkship, on the objective structured clinical examination (OSCE) scores of dental students graduating in restorative dentistry. Materials and Methods: The OSCEs consisted of two stations designed to assess students' clinical skills regarding cavity preparation for a class II gold inlay and a class IV composite restoration. The clerkship achievements, consisting of the number of student clinical procedures performed, observation-related OSCE, and scores of their attitudes towards a conservative dentistry clerkship, were assessed. Correlation and multiple regression analyses were conducted. Results: The correlation coefficient between the OSCE scores for cavity preparation for a class II gold restoration and clerkship attitude scores was 0.241 (p < 0.05). Regarding a class IV composite restoration, OSCE scores showed statistically significant correlations with the observation (r = 0.344, p < 0.01) and attitude (r = 0.303, p < 0.01) scores. In a multiple regression analysis, attitudes towards a clerkship (p = 0.033) was associated with the cavity preparation for a class II gold inlay OSCE scores, while the number of procedure observations (p = 0.002) was associated with the class IV composite restoration OSCE scores. Conclusions: The number of clinical procedures performed by students, which is an important requirement for graduation, showed no correlation with either of the OSCEs scores.

The preservice elementary teachers' achievement goal orientations(mastery/ability-approach/ability-avoidance/work-avoidance goal) for science teaching were measured. The student teachers(91 males and 127 females) tended to have the mastery or ability-approach goals rather than the ability-avoidance or work-avoidance goals for science teaching. The male students were more learning focused than were the females, while the female students reported stronger work-avoidance goal orientation than did the males. This study also examined how the preservice teachers' achievement goal orientations were related to their science teaching efficacy beliefs(personal science teaching efficacy belief/science teaching outcome expectancy). As expected, the results showed that there were significantly positive relationships between the mastery or ability-approach goals and science teaching efficacy beliefs, while the significantly negative relationships were found between the ability-avoidance or work-avoidance goal and personal science teaching efficacy belief. The educational implications and future directions were discussed.

The main purpose of this study was to investigate the desiarable selection of nursing. The subjects for this study were made up of 144 R.N. in active service at H. University hospital in Seoul. This study was “Choice of nursing seale”as a tool which was MMPI questionare developed by Beaver（1953）, and was consist of the choice of nursing scals made up to 66 items. The finding of this study related to their personality and their work achievement showed very significant differences： the results of this study are： 1. There was a significance of the difference between the responses of 64 student nurses and 64 College Women in Educations Curricular to Beaver score. (p <.001) 2. There was a significance in Beaver's score between high group(above 82) and low group(below 53) according to head nurses' work achievement score (p <.05) 3. This study had relationship between the personality and the work achievement of nurses. For the reason, I suggest that we had to apply to select the appropriate nurses in Health Field as Hospitals.

The purpose of this study is to determine the patterns of differences between genders in science achievement. Eleventh grade, 140 female and male students were sampled from a school in Seoul. According to the analysis results of pilot study, 20 items were finally selected for the main study. To sharpen our interpretations of the factors and provide some confirmation, we supplemented the statistical analysis with a more detailed cognitive study of the items using think-aloud protocols and interviews with student test takers. The analysis of this study took into account the different item formats, contexts, and presentation styles. The findings are as follows: First, there was no significant gender difference between multiple-choice and open-ended items. Second, male students achieved significantly better in the context of everyday life in multiple-choice items. Third, male students favored items presented as written texts. Fourth, in problem-solving process, female students tend to apply their science concepts, whereas male students tend to apply their everyday experiences. The results of this investigation indicate that gender difference in science achievement depends heavily on item characteristics.
