This study focuses on the flow of story and content or related context when using movies as learning materials in a class. A great advantage of using movies is that they have a consistent story and detailed content development. Most teachers, however, tend to concentrate on practical expressions totally unrelated to the story or context of the movie they are using. This way might be efficient in the short run but it is certain that the expressions are unlikely to be retained in long-term memory. This study examines how a story-centered class influences learning of practical expressions and how efficient this approach to learning is. Learning and teaching with focus only on the expressions in a movie shades the meaning of the use of the movie a little. In this study the movie, Cars 2, was used in a course of general education with 150 students enrolled. Various group activities were suggested to immerse students into the story and contents of Cars 2. It was found that a story-centered class is helpful for students to acquire practical expressions and that students' satisfaction level with the class was high.

문장제는 학습자에게 다양한 문제해결의 경험을 제공하고 수학적 지식을 맥락에 적용할 수 있도록 안내하여 학습자의 수학 학습을 더욱 의미 있게 이끌 수 있다. 본 연구는 초등 수학 교과서의 문장제를 실제적 맥락 관점에서 살펴봄으로써 교과서 집필 및 교수 학습 과정에 대한 시사점을 제공하고자 하였다. 이를 위하여 초등 수학 교과서 내 수와 연산 영역의 문장제를 살펴보았으며 구체적인 대안을 모색하기 위하여 미국과 핀란드의 초등 수학 교과서를 참고하였다. 분석 결과, 초등 수학 교과서의 문장제에 부자연스러운 맥락이나 소재를 설정하는 경우, 인위적인 수를 삽입하거나 문장제의 언어적 표현 및 삽화가 명료하지 않게 제시되는 경우 등이 나타났다. 이러한 경우 학습자가 문장제의 맥락을 실생활과 별개의 것으로 인식하거나 문장제에서 요구하는 내용을 이해하여 문제를 해결하기 어려울 수 있다. 추후 교과서 집필 시 학습자를 고려하여 소재를 설정하고 삽화, 도식 등을 적극적으로 활용하며 문장 및 삽화를 더 명료하게 구성하는 등 실제적 맥락을 고려하여 다양한 형태의 문장제를 구성할 필요가 있다.

This study explores how a teacher copes with anomalous situation in primary practical science lesson and what factors affect teacher's strategy to cope with anomalous situations. The method of auto-ethnography was used in order to capture the inner experience of the individual teacher. For this, one of the researchers participated in this study as the teacher participant. Two science lessons that the researcher taught as a teacher were observed by a co-author and video-recorded. However, only one lesson which the teacher experienced the anomalous situation was analyzed. After the lesson, self-interviews were conducted with the co-author. Also the researcher wrote four reflective journals about anomalous situations that she experienced. What has emerged in this study is that anomalous situations were experienced by the teacher while students were doing practical work and while students were presenting their results of practical work. As each anomalous situation was experienced in different contexts, the strategies that the teacher used were different and were affected not only by the personal epistemological belief but also by the socio-cultural context that the teacher was surrounded by. This study has implications to help teachers who have difficulties in coping with anomalous situations.

In this paper, we present a practical place and object recognition method for guiding visitors in building environments. Recognizing places or objects in real world can be a difficult problem due to motion blur and camera noise. In this work, we present a modeling method based on the bidirectional interaction between places and objects for simultaneous reinforcement for the robust recognition. The unification of visual context including scene context, object context, and temporal context is also. The proposed system has been tested to guide visitors in a large scale building environment (10 topological places, 80 3D objects).

In this paper we present a framework for a novel kind of context-aware preference query composition whereby queries for the Preference SQL system are created. We choose a commercial e-business platform for outdoor activities as a use case and develop a context model for this domain within our framework. The suggested model considers explicit user input, domain-specific knowledge, contextual knowledge and location-based sensor data in a comprehensive approach. Aside from the theoretical background of preferences, the optimization of preference queries and our novel generator based model we give special attention to the aspects of the implementation and the practical experiences. We provide a sketch of the implementation and summarize our user studies which have been done in a joint project with an industrial partner.

This study aims to investigate how the four college students interact with one another to discuss and construct meaning in a small reading group. Additionally, this study attempts to examine how the participants played their roles in the group. Data sources consisted of transcripts of the students' interactions, questionnaires and informal interviews, and the researchers' observation notes. The data revealed that the participants contributed fairly steadily to the interactions by checking with own grammatical knowledge, providing lexical information, understanding the micro level context, and presenting the macro level context. Several pedagogical implications are presented for the practical classroom. Findings of the study suggest effective ways to implement group activities in reading classes and a teacher's role for optimum group learning.

Despite the increasing adoption of gamification and its huge potential in tourism, research in gamification is still limited. As preliminary findings show that the effectiveness of gamification depends on the context of its application and the players' use of the gamified app, this paper fills in these gaps: by exploring and analysing the application of gamification in a specific e-commerce tourism context; and assessing the gamification's effectiveness by measuring the players' gamification usage and the latter's behavioural and psychological outcomes. The gamified TripAdvisor website and its Facebook enabled gamification app are used as the specific context of the study. Findings from a survey conducted on TripAdvisor users provide useful practical and theoretical implications to gamification designers and researchers alike on how game mechanics can be designed for enhancing the users' motivation, flow, task involvement and engagement with the 'play' tasks, and so, increasing the gamification's effectiveness.
