This study focuses on student engagement in Chinese middle school mathematics classrooms. By the recording and quantitative analysis on video case, this study explored the main acts and time of student engagement. The data showed that among the student engagements: (1) Students' responses to teacher's question occurred most frequently; (2) Collective responses were much more than the individual responses; (3) Students' responses and classroom practice spent the longest time; (4) The most frequent student engagements occurred in the aspects of classroom practice; and (5) Students rarely asked a question to teachers. The study also suggested that teacher's effective guidance could improve the level of student engagement and the content of classroom practice is very important to the quality of student engagement.

This study qualitatively investigates the nature of the challenges that a student who is highly successful in mathematics faces in learning college-level elementary statistics. The study draws on the constructs of eagerness, flexibility and willingness to characterize the necessary disposition for critical thinking that is essential in learning statistics. The case study is based on data collected through a survey assessment and a follow-up interview with a mathematics major enrolled in an elementary college statistics course at the time of the study. The qualitative analysis relies on the student's verbal descriptions of the challenges he was experiencing in the course. The findings suggest that while his strong inclination towards inquisitive learning and strong understanding of mathematical concepts supported this student's mathematics learning, the same characteristics might have been causing him difficulties in learning college-level elementary statistics.

Purpose: Maintaining a lifelong health is very important. The purpose of this study is to know the perception of youth about health teacher's servant leadership, student's self-efficacy, and health promoting behavior, and the relationship among the variables. Methods: This study used surveys of health teacher's servant leadership, student's self-efficacy, and health promotion behaviors. The subjects were 1,286 elementary, middle and high school students. PASW Statistics 18.0 was used in the data analysis. Percentage, mean and standard deviation, t-test, and ANOVA test were used to compare the difference of the health teacher's servant leadership, student's self-efficacy, and health promotion behavior according to the background variables of the subject. Results: There was a statistically significant difference in the perception of youth about health teacher's servant leadership, student's self-efficacy, and health promotion behaviors according to school level, establishment type, and grade. There was also a statistically significant difference in the perception of youth about student's self-efficacy and health promotion behaviors between male and female student. In addition, student's self-efficacy serves as a positive mediator to the effects of health teacher's servant leadership on student's health promoting behavior. Conclusion: Based on these results, it needs to implement the human resources and policy support for the systematic health education of elementary, middle, and high schools, the development of the program for the teacher's servant leadership, and the health promotion of students in curriculum.

With the availability of real-time educational data collection and analysis techniques, the education paradigm is shifting from educator-centric to data-driven lectures. However, most offline and online education frameworks collect students' feedback from question-answering data that can summarize their understanding but requires instructor's attention when students need additional help during lectures. This paper proposes a content restructure recommendation framework based on collected student feedback. We list the types of student feedback and implement a web-based framework that collects both implicit and explicit feedback for content restructuring. With a case study of four-week lectures with 50 students, we analyze the pattern of student feedback and quantitatively validate the effect of the proposed content restructuring measured by the level of student engagement.

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.

The purpose of this study is to provide the necessarily basic data of the ideal growth of the students by investigating the effect of the student's stress due to the parent's achievement pressure. The sample of this study are In students consisting of 51 boys and 49 girls in the 3rd grade classes of "J" middle school located in Siheung city, Kyungki-do. The observed materials are used to investigate the parent's achievement pressure and the level of stress. Based on the observed data, the frequency, correlation, and t-test have been gained. The results are summarized as follows : 1. The perception of the parent's achievement pressure is shown more by the boy's achievement pressure($44.2{\pm}9.9$) than the girl's achievement pressure($39.939{\pm}11.089$), among the high level students. 2. The perception of the parent's achievement pressure is shown more the high($43.0{\pm}10.7$) and middle($42.9{\pm}11.8$) level students than the low($39.7{\pm}8.00$) level students. 3. The stress of male students was high in the Solving Problem stress factor with by the mean of $15.1{\pm}3.7$, and the stress of female students was high in the Self-Control stress factor with the mean of $13.3{\pm}3.9$. 4. The stress of high, middle, low level student was high in the Solution of Matter stress factor with the mean of $14.2{\pm}3.9$. 5. The results were the main cause of the stress than the parent's achievement pressure.

The purpose of this study is to identify the level of children's consciousness and behavior for the environmental conservation, so that provides some fundamental information for the overcome of environmental crisis and reinforces a consumer education for the childrens at home. The subjects were randomly selected form the 4th, 5th, and 6th grade of elementary school students, in April, 1996, Seoul, Korea. The 1342 data obtained were analyzed by Mean, t-test, ANOVA, duncan's Multiple Rang Test, Pearson correlation, and Regression. The major findings were as follows: 1) The average level of children's consciousness for the environmental conservation was relatively low, which was 1.79. There were significantly differences on the children's consciousness for the environmental conservation, according to student's grade level, housing type, parent's education, household income, and the level of consumer socialization. 2) The average level of children's behavior for the environmental conservation was low, which was 2.36. There significant differences on children's behavior of environmental conservation, according to student's sex, grade level, housing type, parent's education and occupation, household income, and consumer socialization. 3) There were significant relationships between children's consciousness and behavior for the environmental conservation. 4) The most influential variable for children's consciousness and behavior of the environmental conservation was consumer socialization. As we see above, this study concludes that consumer environmental education should be reinforced for the children in the home, so that they involved in the environmental activities and have an early experience.

We developed a test bank system which dynamically adjusts to students' achievement levels. In order to dynamically calculate the student's achievement level, our system uses the question-response theory which is usually adopted to CAT. The system proposes appropriate questions depending on the students' achievement levels so that they can do self-directed and individualized learning. The system consists of pre-test, main learning, and review stages. In the pre-test stage, the intellectual level of the student is examined to determine the starting point in the main stage. In the main learning stage, individualized learning is performed. Finally, a review session is added to re-examine the questions that the student gave wrong answers. The output from the learning process of the system is not the usual test scores but the level of the student's intellectual ability which is produced through the question-response theory. The intellectual ability level index objectively measures the degree of improvement of the student's learning ability.

The purpose of this study is to collect and analyze the student's pre-inquire and to obtain information on how to use the teaching-learning process. The specific research problem is to confirm the level of the student's pre-inquire, to identify the characteristics of each type, and to check what pre-inquire can be used in the teaching-learning process. The research was conducted on 149 children in the $3^{rd}$ and $4^{th}$ grade of elementary school, and collected a total of 2,034 inquires. As a result of analyzing three times, the students' pre-inquires accounted for 90% of Level 2 and Level 3, which are the inquires that give meaningful answers in the teaching-learning process. These results show that the pre-inquires presented before the students take up the new lesson are not low-level inquires and they can present meaningful inquires that can be used for teaching-learning. Next, as a result of analyzing the student's inquire by type, the factual question was the largest with 50%, followed by comprehension question, procedural question, application question, and prediction question. The factual and procedural questions showed that they could be used as learning activities during the teaching-learning process. Comprehension questions included in the wonderment question can be used as a learning question. And the application question is a question that can be applied to deepening activities, and the prediction question can be used in the inquiry and experiment process of learning activities.
