  • School mathematics are composed of five major units of numbers& algebraic expressions, equations & inequalities, functions, figures, and statistics & probabilities. But if we look into the general activities of mathematics teachers in their class, they rather do not take into account students\` cognitive and affective traits or degree of difficulty which each of the unit has. For successful teaching of mathematics, teachers should take into consideration many affective items which influence the students\` scholastic achievement. Among them student\`s liking for the mathematics is commonly accepted as the most important factor for successful learning. In this study, with the five units of school mathematics, we investigated the students\` degree of likings for each unit. To fined out whether there are any differences in students\` likings for the mathematics, between regions and kind of schools, we classified the population according to the locations and kinds of schools. To do this, we divided the whole region into four parts such as Seoul, large city, medium city and town. Moreover, we partitioned the whole secondary school students into four groups of middle school students, vocational high school students, pro-science students of academic high schools, and pro-liberal arts students of academic high schools. From each partition, we sampled similar size of experimental groups which came up to total 1260 students. Analysing the answer sheets which the students responded about the questionnaire, we investigated the following questions using the ANOVA test. 1. Is there any differences in the trend of likings for each unit between the regional classifications? 2. Is there any differences in the trend of likings for each unit between the classifications of secondary schools? 3. What trends of changes are there in the degree of likings for each unit according to the rising of students\` grade?

  • The objective of this research is to search the solution for the difficulties of science and invention gifted middle school students with social and emotional problems that they are faced. The result of this research has shown that the gifted students were feeling difficulties of low self-esteem in their peer relationships, communication and cooperation skills. They were feeling less confident in their stress processing capacity and their multi-processing capacity. Some were also troubled with the intense expectations from their environment and theirselves which led them to feel confusion in their identities and their future. Therefore, instead of education focused on academic achievement and cognitive activity, present education for the gifted must focus on helping to solve the student's social and emotional problems and to strengthen social and emotional skills they need. To achieve this, the education for the gifted students should include a social-emotional learning program, and it should also run a continued and personalized consultation program for gifted students.

  • Currently marketing researchers are investigating the causal variables affecting to salesforces' performances. Some researchers found personal and organizational affecting variables as well as structural context of variables. But almost affecting variables examined in salesforce performance researches are personal characteristics. Such organizational variables like leadership, organization's market orientation would be worth to examine in salesforce performance researches. Thus this research is intended to analyze effects of personal and organizational characteristics on salesforces' performances. Data for this research were elicited from sales representatives of motor companies. Data collected were analyzed by regression analysis using SPSSWIN Ver.10.0. The following are major findings of this research. 1. Leadership whether transformational or transactional affected on salesforces' performances. But it was not accepted that transformational leadership would be superior than transactional leadership. 2. Market Orientation of organization affected on its salesforces' performances. 3. Personal characteristics such as need for achievement, compensation predispositon, self efficacy, learning goal orientation were affect on salesforces' performances. But it found that effects of intrinsic compensation predisposition on salesforces, performances were reverser (-). Based on the above findings, the following conclusion could be drawn: 1. Organizational variables like leadership and market orientation are key managerial variables in the sales organization, meaning that sales manager development and organization's market-driven culture are important. 2.

  • Objectives : Integrative medicine in Korea is the 21st century-style medical practice of two orthodox medical doctrines, traditional Korean medicine and western conventional medicine, as well as complementary and alternative medicine (CAM). CAM with scientific evidence should be incorporated in undergraduate curricula for the purpose of Korean integrative medicine. Methods : Items of detailed objectives, syllabi, textbooks, instructor's experiences, and effectiveness and reason for difficulty of the CAM curriculum for undergraduate students were analyzed and the preference of CAM therapies and others were also evaluated. Results and Discussion : The effectiveness of this CAM class curriculum was high (8.0$\pm$1.4) enough to be used in other Oriental medical colleges. Development of ability for self-study was rated as 7.0$\pm$1.7 and the helpfulness for clinical use was marked as 6.8$\pm$1.9. Students preferred placebo, Ayurveda, aromatherapy, yoga, functional food, bio-feedback and homeopathy. The difficulty degree was 7.2$\pm$1.6, and the amount of content was suggested as the major reason for it. We also found that this curriculum can be a model for self-oriented study and problem-based learning. Discussions were made for the improvement of the implemented CAM curriculum, which was shown to be very effective for the achievement of Korean integrative medicine. Conclusion : We have successfully installed a CAM curriculum for undergraduate students at the College of Oriental Medicine, and it can be used in others.

  • The Ministry of Education have had us practice the performance test as a substitute proposal, however, all the more for the idealistic purport, our education front does not have such a sufficient condition as to practice the performance test for many classes and miscellaneous duties and over-populated class, and that practice has been enforced so abruptly without any drastic preparation and has caused much confusion from the beginning of that enforcement. Thus, these problematic concerns are remained as the tasks of the teachers to be solved by themselves in the front of education, and herein I came to do this research. The followings are the conclusions that I got as the results of the research (1) Performance test style should be applied in consideration of the students' achievement level and the gap of the teachers' recognition; descriptive test, portfolio assignment and formative test styles were proper for the students lacking basic study ability. (2) Descriptive test should have its beginning with the question items to which students can write the problem solving procedure logically rather than those to evaluate the creation ability and thinking ability: and putting down specifically the assessment standard could prevent students' confusion and scheme the impartiality of the assessment. (3) Portfolio assignment evaluation should be given with as interesting and suitable amounts as possible so that the students can do by themselves. (4) Utilizing the performance test table enabled easy management of documentary evidence. And it is needless to say that the success of the performance test should have preceding conditions like the teachers' understanding and their positive participation. Therefore, I'd like to give suggestions herein like the followings; (1) The performance test should not always be made into grades, and there is a need to develop the test gradually in the condition that the education surroundings permit by checking time, frequency, ratio and contents of the test while practicing the multiple choice writing test. (2) As long as the performance test has the aims of improving the studying and learning activities, any performance test only for the sake of making numerals with the thought that assessment is the disposal of the grades should be avoided, and the change of the lecturing styles and development of various assessing types and studying materials should be endeavored to confirm with the aims.

  • This study analyzed the errors of 6th graders of elementary school in problem solving process of the measurement domain. By analyzing the errors that students make in solving difficult problems, this study tried to draw implications for teaching and learning that can help students reach their achievement standards. First, though the students were given enough time to deal with problems, the fact that about 30~60% of students, based upon the problems given, can't solve them show that they are struggling with a part of measurement domain. Second, it was confirmed that students' understanding of the unit of measurement, such as relationship between units, was low. Third, the students have a low understanding in terms of the fact that once the base is set in a triangle then the height can be set accordingly and from which multiple expressions, in obtaining the area of the triangle, can be driven.
