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 investigated student's prior conceptions and evidence evaluation about Light and shadow. One hundred twenty six students were given Explanation-after-choice type Questions to investigate student' prior conceptions and Choicd type Question to identify student's idea about scientific method and characteristics od observation. Forty-four of the 126 students were interviewed to explore student's evidence evaluation. Eighty students (63.5%) thought that the shape of material affected the shape of shadow but the shape of light source did not Only 58.8 precents of all responses were evidence-based responses. Characteristics of evidence affected student's evidence evaluation : student made evidence-based responsed to the accord evidence more frequently than discord evidence. Among evidence-based response to the discord evidence. 35.5% of responses were the case that student felt cognitive conflict or explored other variables by recognizing discord between his/her own ideas and evidence or distort the evidence. Student's idea about characteristics of observation did not affect the evidence evaluation, but student's idea about scientific method affected the evidence evaluation.

This study describes a sixth-grade teacher's professional development journey through action research for improving students' responses in a mathematics class. In the action research, the influence a teacher's questioning tactics would have on students' ability to determine answer reasonability to mathematics problems was investigated. Drawing on qualitative analysis of the teacher's lessons, reflection journal and interviews as well as the classroom students' questionnaires and interviews, this study examines how action research can affect the teacher and the classroom students. The results suggest the popularization of action research among teachers by teacher training and development programs showing the positive changes in the teacher's performance leading to improved student responses.

Many students have misconceptions that upward direction force act on the object which is moving upward after being thrown vertically upward, and no force act on the object at the top of its flight because the object stop or don't' move at the top. To change these misconceptions, in this study, deductive reasoning tasks were used, and student's responses to the tasks were analyzed. In the first part of this study, student's prior conceptions about force and motion and student's deductive reasoning abilities were investigated. And the second part, student's explanations were classified to either the premise-based or idea-based explanation. In the case of the object which is moving upward, 62% of students who had misconception changed their misconceptions to physically correct concept, but, only 24% of students changed their misconceptions for the object at the top. For the first task, more students changed their misconceptions when they made responses based on premises than based on their own idea(p<.05), so, the first task can be helpful for conceptual change. 40% students changed their own misconception by reasoning deductively based on premises provided in the first task, but only 17% students changed by the second task. Student's reasoning abilities investigated in the first part of this study did not affect the conceptual change. Four students for the first task and one student for the second task did not change their misconception even though they made premise-based explanation and had high reasoning abilities.

From a social constructivists' perspective, knowledge is not transmitted by language but it is constructed by social interactions with others. That is, it is viewed in social constructivism that learning is a process in which knowledge is constructed by communicative interactions with more capable others. In this vein, a class might be analyzed and characterized in terms of interactional patterns of teacher-student and student-student in class. For this, a primary math class was selected and observed and it was analyzed by the Flanders category system to investigate the effects of the math teaching based on verbal interactions on the learning of math. The class was taught in a teacher-centered and direct way but in the class math knowledge was taught through univocal communications in the form of question-answer. The results of this study appeared to suggest that verbal interactional patterns should take place frequently in math teaching in the sequence of a teacher's questions$\to$students' extensive responses $\to$ positive feedback for the students' responses by the teacher $\to$ the acceptance of the students' responses $\to$ the teacher's explanation or students' questions. In other words, math might be taught more effectively through the verbal discourse patterns proposed in this study.

Recent development of teachable agent provides learners with active roles as knowledge constructors and focuses on the individualization. The aim of this adaptive agent is not only to maximize the learner's cognitive functions but also to enhance the interests and motivation to learn. In order to establish the relationships among user characteristics and response patterns and to extract the algorithm among variables, we measured the individual characteristics and analyzed logs of the teachable agent named KORI (KORea university Intelligent agent) through the student modeling. A correlation analysis was conducted to identify the relationships among individual characteristics, user responses, and learning outcomes. Among hundreds of possible relationships between numerous variables in three dimensions, nine key user responses were extracted, which were highly correlated with either individual characteristics and learning outcomes. The results suggest that certain type of learner responses or the combination of the responses would be useful indices to predict the learners' individual characteristics and ongoing learning outcome. This study proposed a new type of dynamic assessment for individual differences and ongoing cognitive/motivational learning outcomes through the computation of responses without measuring them directly. The construction of individualized student model based on the ongoing response pattern of the user that are highly correlated with the individual differences and learning outcome may be the useful methodology to understand the learner's dynamic change during learning.

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.

The purpose of this study was to analyze differences of the indoor environment and student's fatigue response according to ventilation in university lecture hall. The experiments consisted of measuring the indoor environmental parameters and a survey of student's responses. The experiments were in the lecture hall that the actual lecture was conducted in on the $25^{th}$ of May 2009 (not opening windows and door- A) and the $1^{st}$ of June 2009 (opening windows and door- B). The experimental variable was ventilation by opening the windows and door, and the controlled conditions were indoor temperature by air conditioner, volume of the microphone and VTR, lighting conditions and teaching method. The results are as follows: 1) The indoor temperature was maintained in controlling A, B but the $CO_2$ and relative humidity of A (average 3579ppm, 62.6%) was higher than B (average 1697ppm, 48.1%). 2) There were differences in the student's subjective responses and student's fatigue responses between A and B. 3) Therefore, it was found that ventilation by opening the windows and door was a valid way to improve the relative humidity and to reduce $CO_2$ in the lecture hall.
