The aim of the National Assessment of Educational Achievement (NAEA) is to produce specific and reliable resources required for the diagnosis and quality control of teaching and learning by measuring the level of students achievement based on the national curriculum. In 2002, we introduced ‘modified Angoff Method’ to obtain more systematic and rational results about the achievement levels. The result indicated the differences of achievement level according to the differences of sexes. Female students achieved higher scores than male students in Grade 6. Male students achieved higher scores than female students in Grade 9 and 10. Furthermore it disclosed a problematic phenomenon that students in small towns and rural areas showed significantly lower scores in all six sub-areas of Mathematics compared with students in metropolitan and cities. The results from the NAEA listed above could be used as the authentic data for improving national curriculum and teaching and learning methods, the establishment of educational policies, and many other areas.

This study was carried out to develop a physics education program for foreign students of university in Korea to improve their ability to major in the field and to prevent them from becoming dropout. The subjects of the study are five Chinese students attending a natural science and engineering college. Prior to the development of the physics education program, the researchers developed basic physics textbooks for the foreign students and questionaries for diagnosis and summative evaluation, and utilized them to apply a total of seven classes. After the application of the classes, the results of the student's diagnosis and summative evaluation, the teacher's diaries, the observer's diaries, and the transcripts were analyzed by triangulation method. In addition, Nvivo12 was used for the analysis of the teacher's and observer's diaries to help with qualitative analysis. The results of the study are as follows: First, the oder and contents of physics education program for students of the natural science and engineering college were presented in detail, and basic physics textbooks and tools for diagnosis and summative assessment were developed. Second, as a result of the analysis of the diagnosis and summative assessment results of the program, the students' basic physics achievement improved by an average of 40 points due to the application of the developed program. Third, as a result of the application of the program using Nvivo12, meaningful node and actual cases were extracted. There were 10 types of nodes created such as understanding of the students, teaching method, rate of the participation, level differences, language problems, relevance to majors, curriculum and methods of education in the country of origin, cooperative learning, and interest inducement.

Background: Oral cancer presents with high mortality rates, and the likelihood of survival is remarkably superior when detected early. Health care providers, particularly dentists, play a critical role in early detection of oral cancers and should be knowledgeable and skillful in oral cancer diagnosis. Purpose: The aim of the present study was to assess the current knowledge of future Yemeni dentists and their opinions on oral cancer. Materials and Methods: A pretested self-administered questionnaire was distributed to fourth and fifth year dental students. Questions relating to knowledge of oral cancer, risk factors, and opinions on oral cancer prevention and practices were posed. Results: The response rate was 80%. The vast majority of students identified smoking and smokeless tobacco as the major risk factors for oral cancer. Most of the students (92.6%) knew that squamous cell carcinoma is the most common form of oral cancer, and 85.3% were aware that tongue and floor of the mouth are the most likely sites. While the majority showed willingness to advise their patients on risk factors, only 40% felt adequately trained to provide such advice. More than 85% of students admitted that they need further information regarding oral cancer. As expected, students of the final year appeared slightly more knowledgeable regarding risk factors and clinical features of the disease. Conclusions: The findings of the present study suggest that here is a need to reinforce the undergraduate dental curriculum with regards to oral cancer education, particularly in its prevention and early detection.

The purpose of this study was to describe the latent characteristics of psychological health of child outpatients and their parents visiting Korean traditional clinic with physical complaints and was to propose an alternative curriculum to meet their needs based on their psychological and physical aspects. Methods: Subjects studied consisted of 100 outpatients (59 boys, 41 girls, mean age 55 months, age range 18 to 83 months) and their parents. Behavior characteristics for children were measured by Korean version of Child Behavior Checklist for Ages 1.5-5 (CBCL1.5-5) while parenting stress, depression, and anxiety for parent were measured by Korean-Parenting Stress Index-Short Form (K-PSI-SF), Center for Epidemiologic Studies Depression Scale (CES-D) and State-Trait Anxiety Inventory (STAI), respectively. The data of subjects were compared to those of standardized groups and then were compared according to child's gender within sample. Results: Child participants were reported to have significantly higher scores of all CBCL 1.5-5 subscales than the standardized group. When compared, no differences of K-PSI-SF, CES-D, and STAI was found between parents of participants and the standardized groups. However, parents of child participants with at-risk psychological problems showed significantly higher scores of all parenting stress subscales than those of all child participants. In addition, the mothers of boy participants demonstrated significantly higher anxiety, depression and parenting stress than those of girl participants irrespective of psychological severity. Conclusions: We discussed the implication of these results in clinical situation and make recommendations for curriculum of psychiatry and pediatrics with the aim of improving proper diagnosis, consulting and treatment.
