Abstract—The purpose of this research is to develop the reflection using video based on Gibbs’s cycle in electronic portfolio to enhance the level of reflective thinking of teacher students. The model was developed based on the review of literature and the experts’ evaluation. Then, it was tested by 21teacher students, followed by the approval from the experts. Data analysis indicated that there was statistical difference between pre and post test scores at .05 level of significance. The results of this study showed that the model should consist of seven steps as detailed in the article. Index Terms—Electronic portfolio, reflective thinking, video reflection. I. INTRODUCTION Reflective thinking towards learning plays a part in helping the studentsachieve the goals and realize the purposes of thinkingto reach learning targetsand bring knowledge for integration. Reflective thinking process arises from training the students to have the skill in thinking reflectively and considering various things carefully by means of causes and effects. As a result, the individuals can review and reflect on their actions, causing theunderstanding and learning from experience. This leads to development, improvement, solving of various problems [1]. It helps train the students to develop a flair for analysis of their performance, planning, presentation of approach to development, correction and improvement up until planning for applications in practice. As to evaluation of reflection to examine the students’ results towards learning and working,it is possible to assess the classified levels of reflection capabilitytowards the work of students called "level of reflection." Such level of reflection isin the developmentally-orientated form. Besides, there isthe presentation of level in which the reflective thinking of learner is. Also, it is feasible to make progress through the stages of reflection process development further [2]. Regarding the use of video as a tool for presenting one’s own story or commenting on the work, this is also a way to develop the communication skills of students through videoprepared on one’s own. According to the explanation Manuscript received August 30, 2014; revised September 29, 2014. This work was supported by the T.H. 90 th Anniversary of Chulalongkorn University Fund (Ratchadaphiseksomphot Endowment Fund) for funding this research. The authors are with the Department of Educational Technology and Communications, Faculty of Education, Chulalongkorn University, Bangkok 10330, Thailand (e-mail: siesta_cop@hotmail.com). provided by Nawanit Songkharm [3], the educational management by giving students the opportunity to present themselves via video called "digital video" as a medium for reflection promotion in the manner of communicating knowledge and experience from learning through piece of work is helpful in the process of self-reflection. Besides, communicating one’s own story will allow the learner to reflect on experience, opinions through expression to help develop skills in various fields. The work of students, which is stored and presented, is intended for use in the authentic assessment of learners’ performance. Electronic portfolios are widely utilized as a tool for storing the work of digital media type. The purposes are to show the evidence of students’ progress and opinions of the students about their own learning. In this regard, the students store the work of all kinds according to classification set by the system. Concerning the work stored, the students must also feel that they themselves decide on which work to store. The opinions of learners will allow them to take responsibility for their own learning, which can be utilized in various fields and serve as a channel of developing students in terms of reflective thinking. Moreover, the students’ comments are concluded for use in adjusting educational management with the display of results in relation to effective learning. II. REVIEW OF LITERATURE From the outcomes of studying literature and related researches, the information on various issues is presented as follows: A. Reflective Model Reflective thinking is a process of checking and searching forthe object of one’s interest. It will arise out of stimulation from various experiences of the past and leads tothe change of perspectives and ideas to the new ones. Therefore, such reflective thinking process is considered as a context of learning through the process of intellect and attitudes towards actions. Each person can find this from one’s own existing experience, leading to the understanding and acceptance of new things. Also, it is considered that reflective thinking is a person's potentialfor learning, which results in the change of perspectives. It will happen in the manner of a process. One important thing is that reflective thinking must be done straightforwardly. This would resultin seeing the information or errors truly, accepting the changes and correction so as to lead to learning the approach appropriate forsuchgiven situation.
