  • This study examined the knowledge and practices of scientific inquiry displayed by three student teachers and two beginning teachers at secondary levels. Observations using the instrument of OTOP designed by the research team of OCEPT (Oregon Collaborative for Excellent in the Preparation of Teachers) generalized similar teaching strategies of scientific inquiry between student and beginning teachers, such as using group work for students' first hand experience, using concrete materials for experimentation or visual tools for demonstration, using questions for factual knowledge mainly without opportunities to understand how scientific knowledge is constructed. Those scientific inquiry activities were very confirmative ones to follow the steps without opportunities of understanding nature of science or nature of scientific inquiry. However, all participants in this study hold knowledge of scientific inquiry envisioned by the National Science Education Standards [NSES] (NRC, 1996), where students identify their hypothesis, use critical and logical thinking, and consider alternative explanations through argumentation as well as experimentation. An inconsistent relationship between participating teachers knowledge and practices about scientific inquiry resulted from their lack of pedagogy skills of implementing it in the classroom. Providing opportunities for these teachers to reflect on their beliefs and practices about scientific inquiry was recommended for the future study. Furthermore, increasing college faculty interest in new teaching approaches for upgrading the content knowledge of student teachers and beginning teachers was recommended as a solution, since those teachers showed evidence of influence by college faculties at universities in their pedagogy skills.

  • Purpose: The study has been undertaken on several factors that may influence on the orthodontic treatment satisfaction with the subject of male and female university students who have experience in receiving the orthodontic treatment by visiting orthodontic clinic. Methods: This study has implemented questionnaire survey for 350 male and female university students who have experience in receiving the orthodontic treatment by visiting orthodontic clinic due to the mall occlusion, From the 350 questionnaires collected, a total of 291 copies (83.1%) excluding the questionnaires that have inconclusive response or erroneous response is used as the research analysis data Results: The orthodontic treatment satisfaction is significantly higher for students in large cities and mid- to small sized cities than students in rural area, and it was higher for students with mid-economic class that students of upper class and lower class. It is shown for a student that began the orthodontic treatment from the elementary school, a student that had 5 times or more of brushing teeth for each day had significantly higher level of satisfaction that students that are not. In addition, a student that knows well of the oral hygiene management method, a student that had the fluoride application treatment during the orthodontic treatment period and a student that used the toothbrush for orthodontic service had significantly higher level of satisfaction that students that are not. Conclusion: Factors influencing on the orthodontic treatment satisfaction are very diverse and it is considered that it requires effort to improve the quality of medical service and sufficient understanding on several factors to improve the orthodontic treatment satisfaction for patients as well as the encouragement for orthodontic treatment patients of the relevant people in orthodontic clinics that provide the orthodontic clinic service.

  • The aim of this study is to show that using a Web-Based Instruction system is a better method to help counteract deficient teaching, learning conditions and facilities thus improving the students' interest, understanding, participation and skill development in Physical Education. The key findings of this study are as follows; The first advantage of using this system is that the theory of Softball is explained with the use of pictures rather than text, thus improving the students' understanding. The second is the method in which practical skills are explained and demonstrated. Action image sequences are used as opposed to the old method of using stationary pictures. This means that the learners can clearly see and understand why and, more importantly, how to use these skills. The third advantage is the technique used to teach the application of these skills. Using active rather than passive learning and thus engaging the student encourages improved participation and learning. The fourth advantage comes in evaluation: both subjective and objective questions are asked in theoretical evaluation, and the teachers can evaluate the students' understanding and skill development by filming their actual Softball games. The final advantage is the use of Self-Directed Learning to aid learners' development of understanding of the lesson content as interactions between teachers and learners are constructe

  • Virtual university can easily study the lecture only press the couple of mouse click or keyboard button anywhere and anytime, if you have a computer. Many people believe that virtual university, can save time and improve learning. To check how many students learn which selected some of virtual university courses, instructor must knows how to the understanding students and find out their difficult problems. Without checking this condition, it will be a very difficult and boring virtual university course. In this paper, we introduce the intelligent learning system. It has a full duplex direction that teachs understanding students and not understanding student. The computer simulation results confirms that full duplex virtual learning system has been proven to be much more efficient than one way direction which unfortunately does not consider to understanding problems.

  • The purpose of this study is to explore the characteristics and the level of fourth grade elementary students' system thinking when they learn the unit of "Journey of Water" in terms of four key elements of system thinking such as understanding of the structure of a system, non-linearity and cyclic features, inter-relations and feedback between system properties, and temporal and invisible aspects of a system. Data included students' worksheets and their responses to a set of Likert-scaled and written assessment items on water cycle. The results showed that the level of students' system thinking did not have any hierarchy in relation to the key elements of water cycle system. In addition, the aspects of individual student's system thinking on its sub-elements were different from each other. Also, there were core ideas of system thinking which were intensively considered according to a given context to understand a complex systemic subject. When students learn water cycle, understanding of non-linearity and inter-relations were weaker compared with other key elements of system thinking. Therefore, if these two factors are taught in advance, it can promote understanding of whole system of water cycle.

  • Among many remedial approaches against the increasing unfavorableness toward school science, one of the prevalent findings studied by affective experts is that students' achievement in science and their attitude toward it has a relatively weak relationship. In contrast, cognitive experts assert that the conceptual change involves more than cognitive aspects, and may be influenced by affective factors such as beliefs, motivation, learning attitudes, and sociocultural contexts. The latter regards continuous conceptual change as leading to better student understanding of science with variables of students' attitude toward science. As an initial step toward illuminating the affective-cognitive learning aspects of science, the purpose of this study is to develop an instrument for analyzing the relationship between students' conceptual understanding and affective factors. Cognitive questionnaires from the database of distribution in students' misconceptions of physics (DMP project), and affective questionnaires from the Relevance of Science Education (ROSE project) are integrated into our instrument. The respondents are high school students in Okayama prefecture, Japan. Through the pilot test, the authors integrated attitude toward science (AS) and interest inventory (II) from ROSE into cognitive understanding (CD) from DMP. Statistical methodologies such as factor analysis and item total correlation theoretically discerned the effective sixty-three items from the two original item pools. Having discussed two validity issues, the authors suggest ongoing research associated with our affective-cognitive research perspective.

  • The purpose of this study was to investigate culinary arts and hospitality students' food safety practice behaviors, intentions, attitudes, and barriers to food safety compliance. This descriptive study used the self-report questionnaire. The convenience sample was composed of 266 college students majoring in culinary arts and hospitality. The students indicated that they never or rarely use a thermometer to determine if meats have been adequately cooked. Examples of positive food handling behaviors were hand washing, sanitation of fruits and vegetables, discarding of food past its expiration date, counter top sanitation, and proper food storage. Students strongly agreed it is their responsibility to practice food safety and to educate their employees about food safety. The primary barrier to proper food safety as ranked by student respondents is the misunderstanding about food labeling. Previous food safety education and internship experience appeared to improve the student respondents' perceived attitudes toward following the principles of food safety practices (p < 0.05), although behaviors and intentions to use the correct food safety practices were not affected. The findings of this study suggest that programs should consider integrating information and experiential learning opportunities in their courses that would be enhance student understanding about food safety. The outcomes of this study can be applied to develop food safety education materials and programs for culinary arts and hospitality students.

  • The 2009 revised curriculum has been revised to increase the time allocated to creative discretion. Accordingly, in many schools, discretionary activities have been replaced by reading and essay writing. However, these activities do not differ from existing classes and student's interest in those activities is minimal. This study has applied two kind of the AR program, which is designed and implemented using Smartphone in the classroom, to increase student's interest. A browser-based AR, created by Junaio and QCAR-authored Smartphone-based AR fairy tale book, are easy to use in class by the students themselves. We applies to Fourth grade student in reading education this AR programs. As a result of test, the students in actual reading classes responded that their interest in the lesson and their understanding of fairy tales has increased.

  • This study presents how two eighth grade students generated their own algorithms in the context of fraction measurement division situations by modifications of unit-segmenting schemes. Teaching experiment was adopted as a research methodology and part of data from a year-long teaching experiment were used for this report. The present study indicates that the two participating students' construction of reciprocal relationship between the referent whole [one] and the divisor by using their unit- segmenting schemes and its strategic use finally led the students to establish an algorithm for fraction measurement division problems, which was on par with the traditional invert-and-multi- ply algorithm for fraction division. The results of the study imply that teachers' instruction based on understanding student-generated algorithms needs to be accounted as one of the crucial characteristics of good mathematics teaching.
