A Theoretical Framework of Ecosystem of Learner Development for Designing a Practical Ubiquitous Learning Environment

Over the past decade, the application of results from brain science research to education research has been a controversial topic. A NIRS imaging system shows images of Hb parameters in the brain. Measurements using NIRS are safe, easy and the equipment is portable, allowing subjects to tolerate longer research periods. The purpose of this research is to examine the characteristics of Hb using NIRS at the moment of understanding. We measured Hb in the prefrontal cortex of children while they were solving mathematical problems (tangram puzzles). As a result of the experiment, we were able to classify the children into three groups based on their solution methods. Hb continually increased in a group which could not develop a problem solving strategy for the tangram puzzles. Hb declined steadily for a group which was able to develop a strategy for the tangram puzzles. Hb was steady for a certain group that had already developed a strategy before solving the problems. Our experiments showed that the brain data from NIRS enables the visualization of childrens mathematical solution processes.

Changes in Subjective Understanding of an Accident and Risk Awareness in First-Year Nursing Students Following Medical Accident Simulation-Based Experimental Learning

We discuss the possibility of Near Infrared Spectroscopy (NIRS) application to the educational research. NIRS system was used for prefrontal cortex measurement of children, when they were solving Mushi-kuizan problems. The Mushi-kuizan task is one of the mathematical puzzles. Subjects were four children in fifth grade. Hemoglobin parameters such as oxygenated hemoglobin and deoxygenated hemoglobin were calculated during Mushi-kuizan problems. The parameters were compared with the performance data of each subject. Changes Hb parameters described how children use their brain. NIRS evaluated the thinking process of mathematics task. It is very useful for mathematics teachers to catch the childrens thinking process dynamically because they can consider the way of teaching for each child. It was shown that NIRS may be able to apply to education.

Construction and Application of Foreign Language Teaching Aid System Based on Knowledge Visualization

The paper proposes a theoretical framework of knowledge spiral-based ecosystem of learner development for designing a practical ubiquitous learning environment, which is based on theories of social constructivism. Through describing the model, we argue that ubiquitous learning environment should be embedded in an educational information infrastructure and blending used with traditional learning technology in practice. In the paper we connect technical view, pedagogical view, sociological view and cross-cultural view and suggest implementation should be in the context of authentic world. We offer two cases of pilot studies as trials to describe how to design such a seamless learning space using this model.

A Documentation Platform for Supporting and Assessing Collaborative Knowledge Building in Learning Computer Programming

Novice nurses with little professional experience tend to feature frequently in reported medical accidents and near-miss incidents in Japanese healthcare facilities. According to our previous survey, approximately 40% to 70% of nursing students experience near-miss incidents during their clinical training. Many of these incidents in nursing settings occur while providing assistance for wheelchair transfer or bathing. Fostering observational skills to enable accurate risk area identification is a requirement from the stage of basic education for the provision of safe medical care to patients. In the present study, we devised and implemented experimental learning aimed at first-year nursing students that incorporated medical accident reenactments and simulations using simulated patients. The results showed significant post-learning increases in both subjective understanding and the frequency of risk area identification, suggesting that experimental learning improves nursing student comprehension and skill in responding to perceived risks.

Measurement of brain activation difference during different mathematical tasks by near infrared spectroscopy

In order to realize the relevance and visualization of knowledge, this paper presented a teaching aid system to visu-alize the knowledge points of foreign language, and described the verified system function through teaching practices. First, we constructed a teaching aid system with knowledge visualization function. i.e., the system visualized the relevance between knowl-edges and dynamically presented and compared between knowledge points by knowledge map. Second, we built a foreign language knowledge database that includes the needed grammars and vocabularies, and then created a technical knowledge map for knowledge relevance. Finally, we applied the system to teaching practice. Through the investigation of the understanding de-grees of knowledge points and the analysis of questionnaires, we found that the system effectively promoted the relevance and reconstruction of knowledge points, deepened the understanding and communication, so as that promoted the learning initiative of students.

Remote counseling using HyperMirror quasi space-sharing system

This paper presents a documentation approach for promoting students’ knowledge building in learning Computer Programming. The underlying premise is that the documentation process allows students to track their learning, develops transformative communication with teachers, and provides a persistent record of individual work and collective cognition artifacts. Our focus is on practical and collaborative considerations for learning computer programming, and we explore a theoretical instructional design framework that organizes learning activities in order to better engage students in the programming course. A learning platform to support this theoretical framework was developed to give students simultaneous access to a shared online documentation work environment. The students were able to program and do documentation work together in real time, and to invite others to view, check, and comment on their files. The documentation work leading up to the artifact creation showed the students’ improving understanding of programming, especially in their collaborative work. Thus, we show how collaborative documentation work is useful in improving deep constructivism and students’ engagement in knowledge building.

ME203 Remote Counseling using embrace system for stressful person of childcare

This study examines differences in concentration changes of hemoglobin in the brain while finding algebraic solutions versus geometrical solutions. We use Near Infrared Spectroscopy imaging system to measure the hemoglobin changes while subjects are solving algebraic task and geometrical task. NIRS imaging system can measure changes in the concentration of hemoglobin. This brain activity data shows a difference between the two different experimental tasks which helps us to identify the characteristics of thinking processes.
