In this paper, we apply data mining techniques and machine learning algorithms using R software, which is used to predict, here we applied a regression model to test some factor on the dataset for which we assumed that it effects student performance. Model was built on an existing dataset which contains many factors and the final grades. The factors tested are the attention to higher education, absences, study time, parent's education level, parent's jobs, and the number of failures in the past. The result shows that only study time and absences can affect the students' performance. Prediction of student academic performance helps instructors develop a good understanding of how well or how poorly the students in their classes will perform, so instructors can take proactive measures to improve student learning. This paper also focuses on how the prediction algorithm can be used to identify the most important attributes in a student's data.

Based on the Vygotskian perspective that a learner's thinking is constituted in his or her talk and the assumption that student talk in the classroom may occur in more than one way, this study examined discursive practices of students in Korean high school science classrooms. Data came from $11^{th}$ grade earth science classrooms where the Group Investigation (GI) method was implemented. Data source included verbatim transcripts developed from video recordings of class sessions in which students presented their science projects to the whole class and exchanged questions and answers during the presentations. The analysis of the videotape transcripts revealed five different modes of student talk, including 1) retrieving information, 2) reformulating information, 3) building on one's own experience, 4) elaborating current understanding, and 5) negotiating meanings with others. Considering that each of the five modes had different value for learning science, it was recommended that the teacher should engage students in more active modes of discourse and guide them into more sophisticated understanding of science.

Research in undergraduate mathematics education has been active very recently. The purpose of the paper is to investigate how college students make ion from some known informations about integer and rational numbers in algebra. Three college students were involved in the study. We analyze student's personal answers in order to find where their misunderstandings and difficulties come from based on the theoretical frameworks on mathematical understanding such as APOS-model and P-K-model. Finally we discuss about constructivist teaching ways for algebra and propose new paradigm for teaching undergraduate mathematics.

The purpose of this study is (1) to develop native foods in the future continuosly, and (2) to provide basic information allowing college student's to correctly understand traditional culture, by investigating those college students' preference and understanding of the native foods in Cheju-do. To accomplish these purposes, the survey was carried out by use of questionaires for 344 residing in Cheju-do from 20th to 29th May, 1989. The statistical analysis including frequency, percentage, mean and standard deviation was performed by use of SAS program, while the significant difference between groups was examined by $x^2-test$. The results of this study are summarized as follows : 1. It was showed that college man had higher understanding and preference of those native foods than college women. 2. The result relating to age indicated that the more the age, higher understanding and preference. 3. The result by residing areas showed that the college students in the rural area showed higher understanding and preference than students in the urban area. 4. Based on the educational background of those subjects' mothers, it was shown that those college students of mothers having lower educational background had higher understanding and preference of native foods. 5. Those college students having good understanding of native foods accounted for 63.4 percent, while students requiring the continued development of those native foods for 91.0 percent. As a consequence, it is apparent that most subjects tended to show the positive responses to those native foods.

The purposes of this study were to investigate the creative science problem solving (CSPS) process amongst scientifically-gifted students and average students through the qualitative think-aloud research method, and to compare the differences in their CSP, scientific knowledge, scientific process skills, creative thinking, and finally, the affective domain used in their CSPS. For the purposes of this study, two scientifically-gifted 6th grade students and one average student were selected. The results show that one gifted student with good creative thinking skills exhibited better performance in CSPS than the other gifted student, who had the highest level of scientific knowledge. In the case of the average student, in spite of her high level of factual knowledge, she had difficulty in proceeding in CSPS due to her shallow scientific knowledge along with her low level of understanding of the given problem. This study highlights the importance of considering the factors which influence successful CSPS and which can play an important role in the education of scientifically-gifted children. These factors were identified as scientific knowledge, understanding of the scientific process, creative thinking, the affective domain, and science problem solving skills.

The purpose of this study was to help teachers increase the level of student's school life satisfaction by comparing between the practical data of a group which have an accordant perception for class teacher's discipline style perceived by between teacher him/herself and student with another group which have a discordant perception for class teacher's discipline style perceived by between teacher him/herself and student. For this study, 1460 second grade special high school students in Pusan were selected. And 1273 students and 56 teachers' questionnaires were used for analysis, while 5 questionnaires went uncompleted. T-test and Multiple Regression Analysis were used for compiling statistics of collected data. The results of this study are as follows: First, perceptions about the teacher's discipline style perceived by between teacher him/herself and student were different. Second, the levels of student's school life satisfactions were different by two group. A group which has an accordant perception for class teacher's discipline style perceived by teacher him/herself and student shows the high level of school life satisfaction than B group which has an discordant perception. Last, class teacher's discipline style which affects the level of student's school life satisfaction was different by the two group. These results suggest that to increase the level of student's school life satisfaction, class teachers have to a mutual understanding first, and then approach their students with different discipline style by the level of their interactive relationship with their students.

In this study, we studied some examples using GSP(Geometer's SketchPad) in the process of problem solving that is explained by G. polya. After reconsidering examples, we tried to show that using GSP can help student's intuitive thinking, investigative activities, reflective thinking. Especially, in the three phase of problem solving(understanding the problem, devising a plan, looking back), mathematics teachers may using GSP in order to helping student's understanding. Besides, we tried to suggest the direction to use GSP more adequately in the teaching and Beaming mathematics. First of all, Mathematics teachers using GSP in their class must have ideas how to use it. And they have to be careful on the didactical transposition of mathematical knowledge in the computer-based learning. They also have to lead students move from activities with GSP materials to carrying out the problem solving plan and reflection activities.

This research was an attempt to find out an entrance experience into major subject of student nurse. The purpose of this study was to understand an lived learning experience of student nurse. Method of the study was applied a phenomenological approach used by Colaizzi's analytic technique. Participants were 33 sophomore student nurse from TC University. The investigator conducted participated observations and in-depth unstructured interviews which were audio taped under the permission of student nurse, formulating meanings, themes and theme clusters. Results of the study were revealed 6 categories, 14 theme clusters, and 31 themes. Six categories include 'feeling anxious about clinical application', 'making superficial class', 'evaluation for ability of memory', 'deficit of academic evaluation criteria', 'insufficiency of textbook' and 'deficit for uniqueness of nursing science'. This findings confirm the fact that the student nurse's entrance experience was complicated and diversely influenced by their learning experiences. In conclusion, this study will prove helpful not only in understanding student nurse's entrance experience about their specialities but also in developing curriculum for nursing education.

Mathematical Communication ability can be more developed through sharing thoughts with others. Therefore when we instruct students in math, it is very important for teachers to provide them with opportunity to communicate mathematically. So this study provided open-ended problems in small-group collaborative learning. And we analyzed students' mathematical communication focused on the student's level of understanding. Furthermore, to improve students' mathematical communication ability, this study tries to attract the factors that we should consider the exact date for inserting the open-ended problems into a course of math and the student's level of understanding for selecting suitable open-ended problems.

In recent years, there have been several studies on service quality in higher education, however, research on service quality and sustainable activities affecting student loyalty has been largely ignored in previous studies. This paper investigates the role of service quality in creating student loyalty, and how university sustainability practices and student satisfaction mediate the relationship between service quality and student loyalty. The paper draws attention to university sustainability practices and understanding its impact on student satisfaction and loyalty in Vietnamese public universities. A quantitative methodology is explored, and data was collected through an online structured questionnaire. Responses are gathered from 278 students of public universities in Ho Chi Minh City, Vietnam. Structural equation modeling is used to examine the associations between the constructs by using the PLS-SEM approach. The results show that service quality has a significant effect on university sustainability practices, student satisfaction, and student loyalty. In addition, university sustainability practices and student satisfaction also mediate the relationship between service quality and student loyalty. The author's findings may guide the key decision-makers in universities to incorporate service quality and universities' sustainability practices in their strategy and thereby improve student satisfaction and student loyalty.
