Data mining technique was used to track student's performance during years studding in college and determine the impact of GPA_SEC on the GPA student rates according to the current academic advising method used on student's status. The study utilized a sample of 5436 individuals were drawn from two colleges in Majmaah University, KSA during 2013-2018 period. The results showed that the student's completion status in terms of graduation, dropout, Stumbling or dismissed was classified according to the average grades of admission from secondary school GPA_SEC. The results show the effect of the current academic advising that most of students gain less grades comparing with GPA_SEC in addition that the higher GPA_SEC was the higher graduation, dropout and dismissed decreased when GPA_SEC was high.. Therefore, the study recommends tracking students academically to evaluate their results of each semester to find out the causes of the deficiencies and addressing them within the departments.

Proof serves a critical role in mathematical practices as well as in fostering student's mathematical understanding. However, the research literature accumulates results that there are not many opportunities available for students to engage with proving-related activities and that students' understanding about proof is not promising. This unpromising state of instruction of proof calls for a novel approach to address the aforementioned issues. This study investigated an instruction of proof to explore a pedagogy to teach how to prove. The teacher utilized the way of problem posing to make proving a routine part of everyday lesson and changed the classroom culture to support student proving. The study identified the teacher's support for student proving, the key pedagogical changes that embraced proving as part of everyday lesson, and what changes the teacher made to cultivate the classroom culture to be better suited for establishing a supportive community for student proving. The results indicate that problem posing has a potential to embrace proof into everyday lesson.

This study proposed an SCA advice system. It is an ontology-based recommender that provides advice on appropriate computer curricula based on the behavior of high school students. The three computer curricula at Chiang Mai Rajabhat University include computer science (CS), information technology (IT), and web programming and security (WEB). This study aims to design the ontology framework for an SCA advice system. The system considers three core ontologies: student, computer-curriculum, and advice. After analyzing student behaviors, the behavior types of CS, IT, and WEB were determined to be SB-2, SB-1, and SB-5, respectively. All subjects in these three curricula were analyzed and grouped into seven groups. Their curricula were synthesized in terms of basic skills, basic knowledge, and characteristics. Finally, advice results can be obtained by consolidating the curriculum nature of the CS, IT, and WEB curricula.

본 연구의 목적은 고등학생들이 특수 상대론에 대한 이해 수준을 심층면담을 통해 알아보는 것이다. 심층 면담 대상은 8명으로 특수 상대론 기초개념 성취도 체크리스트와 광속불변의 법칙, 상대성의 원리, 동시성의 상대성, 차고 역설, 로켓 역설 등 6가지 상황 단계로 구성하여 심층 면담을 실시하고 분석하였다. 학생들은 특수 상대론과 관련된 단순한 현상의 기억, 개념의 암기 수준에서는 비교적 높은 성취도를 보였으나, 특수 상대론을 설명하는 본질적 원리 이해 수준에서는 낮은 성취를 나타냈다. 심층 면담에서 일부 학생들은 사건의 순서를 관찰자의 직관에 의존하였고, 좌표계를 수학적인 관점에서만 이해하고 실제 상황에서 판단하는 데에는 어려움을 나타냈다. 그리고 관성좌표계를 이해하지 못한 학생들은 상대론적 역설을 자신의 직관으로 설명하였고 학습자 혼돈이 발생하였다. 마지막으로 고등학생들이 형식적 조작기에 속하는 연령이지만 개인적 차이에 의해 시공간의 현상을 이차원 평면에 그리는 활동을 어려워하는 학생들도 있었다.

The purpose of this study is to investigate the interrelationships on integrated science process skills and Piagetian cognitive modes for high school students according to the different cognitive reasoning levels. About 509 high school students were randomly selected for the samples of this study. They were identified as concrete, transitional and formal operational stage with the scores of GALT(Group Assessment of Logical Thinking) developed by Roadrangka, Yeaney and Padilla(1982), and TIPS II(Test of Integrated Process Skills) developed by Burns, Wise and Okey(1983). The result of this study were showed that about 11.8% of the samples were in the concrete operational stage and about 24.4% of the samples were in the transitional stage, while about 63.8% of them were in the formal operational stage. It was also found that the achivement scores of the science process skills increase in accordance with the cognitive reasoning levels. The value of the correlation coefficient between science process skills and cognitive reasoning abilities was 0.49, which was significant at the 0.05 level. This finding seems to support previous research that the student's cognitive reasoning abilities appeared to have influenced student's scores of the science process skills No differences to the logical reasoning ability between male and female students according to each cognitive level were found except formal operational stage.

Quinine quantitative analysis, photo-bleaching, fluorescence quenching, and urine analysis have been performed by means of a UV-LED fluorometer, which can be easily built and used in a high-school laboratory. The quinine detection range is estimated to be 0.05-80 ppm, enough for many classroom luminescence experiments. The quinine content in commercial tonic water is determined from the calibration curve, and UV photo-bleaching of this anti-malarial drug is demonstrated with clear wavelength dependence. Halide quenching of quinine fluorescence is also observed and the increase in quenching efficiency in the order of $Cl^-$, $Br^-$, and $I^-$ is evident. Urine analyses for the student volunteers have been carried out and the results clearly reveal excretion of the ingested quinine. The student participants are exuberant throughout the course of this study and sense the practices resourceful.

연구는 진로탐색 교육이 취업불안, 진로성숙도 그리고 진로의사결정에 미치는 영향을 분석하고자 실시하였다. 광주광역시에 소재한 B실업계고등학교에 재학 중인 비즈쿨 창업교육을 받는 학생 65명을 선정한 후 각각 실험집단 30명과 통제집단 35명으로 구분하였다. 매주 1회 총 9회기의 진로탐색 프로그램을 실시하였으며, 본 연구에서 나타난 주요 결과를 요약하여 제시하면 다음과 같다. 진로탐색 교육에 참여한 실험집단은 참여하지 않은 통제집단보다 취업불안이 감소되었고, 진로성숙도와 진로의사결정이 향상되었다.

Most of the students in middle and high schools today wear school uniforms. The school uniform is the most important and intimate clothes in adolescences and makes students feel a sense of group identity and belonging, and lessen the difference of economical capabilities. However levels of satisfaction is low because school uniforms do not express their individualities and do not keep up with the fashion. In this paper, we studied the partial liberalization of schools uniforms to raise the levels of satisfaction. The subjects were 378 male and female students from middle schools and high school in Ulsan, and a questionnaire was sent out. The survey was conducted in February 2007, and frequency analysis, ${\chi}^2$-analysis, and t-test were used for the analysis of the data. The results are as follows: The students recognized the partial liberalization of the dress code as loosening of the regulation As the result of analysis on attitudes toward the partial liberalization of the dress code, most of the students support the introduction of the plan. They chose a shirt as the most appropriate item and length as the best extent in liberalization. Among the elements of school uniform required to be unified, they selected a jacket and design as the item and extent, respectively. Through this study, we came to know the demands of students for school uniform and confirmed the possibility of the partial liberalization of the dress code as an improvement of consumer-oriented school uniform. In the future, it seems that their desires would be accepted and reflected in the design and school uniforms would be manufactured from the view point of consumer.

The purpose of this study was to investigate the effectiveness of EarthComm implementation in the U.S. high schools in terms of demographic background including school size, urban/rural area, and teachers' teaching experiences. In addition, this study examined impact of students' higher-order thinking skills by using the visions of National Science Education Standards. Two modular of the EarthComm curriculum were used for this purpose with thirty one teachers and around thousand students involved across four states. Findings were that EarthComm did not significantly impact student achievement differentially in schools of varying sizes and school location, i.e., urban and rural areas. The years of teaching experiences did not impact student achievement scores for Module I but did significantly impact for Module II. It is noted that the two results seemingly conflict with each other similar to other research findings (Ferguson, 1998; Yager et al., 1988). Student higher-order thinking skills, on the other hand, were significantly improved as a result of studying with EarthComm. Implications were discussed at the end of the paper.
