Today, a computational thinking course is being introduced in elementary, secondary and higher education curriculums. It is important to encourage a creative talent built on convergence of computational thinking and various major fields. However, proper analysis and evaluation of computational thinking assessment tools in higher education are currently not sufficient. In this study, we developed a rubric to evaluate computational thinking skills in university class from two perspectives: conceptual learning and practical programming training. Moreover, learning achievement and relevance between theory and practice were assessed. The proposed rubric is based on Computational Thinking Practices for assessing the higher education curriculum, and it is defined as a two-level structure which consists of four categories and eight items. The proposed rubric has been applied to a liberal art class in university, and the results were discussed to make future improvements.

The Web programming techniques like CGI and server-sided script languages such as ASP, PHP and JSP have been used for developing on-line Web-based learning systems on SQL. But, the systems developed by using those techniques are dependent on the platforms on which the target DBMS's are located. Therefore, they can be hardly reused and maintained. In addition, it is not easy for them to provide a learner with the feedback information on processing his/her query and to give a teacher an opportunity of monitoring and guiding learner's learning process. In this paper, we propose an SQL learning system on the Web by using Java Applet and JDBC, which is independent on the target DBMS's. Moreover, it gives feedback information on learner's queries so that a teacher can monitor the learning process and teach them efficiently.

This study is to identify the awareness and performance of hand washing according to the presence of clinical practice experience of paramedic students and provide basic data of education on hand washing that can be practically applied. 335 students in paramedicine department in P city and J city were the study subjects and we distributed URL to those who agreed to participate in the study to carry out untact survey using questionnaire. The study results were analyzed by using SPSS/WIN 23.0. The results showed that the average number of hand washing per day was 5~8 times (142 students, 42.4%) and average time for washing hands was 24.34 seconds. We could find statistically significant differences in 'hand washing to wrist' and 'it is necessary to completely dry after hand washing' in terms of difference on awareness of hand washing according to the clinical experiences (p<0.05). In terms of differences in hand washing performance according to clinical practice experience, statistically significant difference was found in 'before touching equipment for clinical practice' and 'before taking foods such as drinks during practice' (p<0.05). The correlation between awareness and performance of hand washing showed that if awareness of hand washing is high, its performance is increased, too (p=0.001). We try to provide basic data of education on hand washing that can improve awareness and performance on hand washing based on the results of this study.

In this study, we developed a simulation app that performs the Test-and-Set algorithm. The test-and-set algorithm is a highly difficult algorithm, so this simulation app was created for learners who have difficulty understanding it. Learners who want to understand the Test-and-Set algorithm gather to form a team, and use this simulation app to discuss and practice, and these teams can practice at the same time. The test-and-set, which is assumed to be a machine language, is not interrupted by using a queue, and it can be seen that the configured simulation app performs well in all three conditions of 'mutual exclusion', 'progress', and 'bounded waiting' that must be solved in the critical area problem.

This study was to investigate the perception of middle school students on the management of the curriculum $\ulcorner$Technology Home Economics$\lrcorner$ according to the 7th National Curriculum. The subjects were 494 third grade students from middle schools located in Seoul, in order to inquire into their perceptions through the questionnaire. The collected data was analyzed with the descriptive statistics, Pearson Chi-Square, t-test, and one-way ANOVA by SPSS Win ver. 12.0 program. The major findings were as follows: Firstly there were gender differences on the interests for the subject of $\ulcorner$Technology Home Economics$\lrcorner$. The girls who were interested in the subject were much more numerous than the boys, but only in the technology part of it, the boys were more interested than the girls. Secondly the students recognized that the experiment & practice for learning $\ulcorner$Technology Home Economics$\lrcorner$ was important. They, however, recognized that its operation in school was not enough to understand the contents. The higher a student viewed the importance of the experiment & practice on $\ulcorner$Technology Home Economics$\lrcorner$, the higher his perception of its usefulness in real life. Thirdly the highest ranking of its usefulness for the contents of the subject $\ulcorner$Technology Home Economics$\lrcorner$ was identified as 'the Computer and Information Processing' and 'the Nutrients and Diet in Adolescence'. These findings suggest that the importance of the experiment & practice was enhanced and the gender differences on the usefulness of the experiment & practice on the each units were considered in order to increase the degree of the students' interest and usefulness of the $\ulcorner$Technology Home Economics$\lrcorner$
