Decision support system for the composition of the examination problem

Abstract This paper considers an educational decision problem, which is to compose an examination problem by utilizing the information of test results and selecting one question from each field. The alternatives, that is, the combinations of questions, are enumerated so as to hit given targets of the appropriateness of questions, the correct answer rate, and the distribution of difficulty. This problem is formulated as a target problem which is defined newly in this paper. Some alternatives are found with the branch and bound method. The best or optimal combination is presented among the alternatives with the analytic hierarchy process. This procedure is constructed as decision support system.

Evaluation of the Change of Work Using Simple Electroencephalography

Abstract We have been developing systems using distance learning and blended learning. In our experience, no equipment has ever been able to measure human states easily. Inexpensive electroencephalograph sensors have become available lately, which enable us to measure electroencephalographic information, and thereby to monitor human states and to obtain information easily as digital data. This report describes that β/α is raised by brain activation. This study assessed an electroencephalogram taken during monotonous work using a simple electroencephalograph. Experiments revealed that the β and γ waves appearing as components in the frequency analysis by electroencephalography are closely related to the subjects work-related skill level.

Learning System Using Simple Electroencephalograph Feedback Effect During Memory Work

Abstract Simple electroencephalographs (EEG devices), which have recently been used commercially to an increasing extent, are portable and wearable to a degree that they do not restrict a wearers actions. This convenience of use allows the ordinary use of electroencephalography inexpensively and widely. This study examines the construction of a simple EEG system that can feed back obtained EEG information for instruction assistance in distance learning. This paper presents an investigation of the relation between two wavelengths: low-γ that reacted during memorization work in the experiment last year, and θ waves that indicate a reaction in a short-term memory domain designated as working memory. Then a support system using the properties thereof was constructed. An experimental comparative analysis of correlation was conducted using electroencephalographically obtained data of students’ memorizing work from actual electroencephalogram measurements. The results revealed synchronized behaviour of (θ + α)/10 and low γ . Furthermore, a prototype system using the properties of these two wavelengths was constructed. Change in memory by the existence of a support system has demonstrated the effectiveness of (θ +α)/(10 × low_γ) as an index for measuring the extent of memorization.

Distance learning support system for game programming with Java

In recent years, students have confronted the importance of developing intermediate level programming skills. Many students are weak not only in programming; they are also not good at cooperation and collaboration when designing a program. Therefore, we produced a distance-learning support system using Java. Generally, students can acquire knowledge that is constant in distance learning, but they find that it is difficult to finish a program independently. In distance learning, it is important to use mutual teaching and regular communication among students. When interesting programming of contents exists, games can make more effectively using Java software. This paper presents Java programming techniques that are necessary for game programming. Moreover this system supports upper level functions of game programming.

Change of Attitude in Class for Creating Slides to Present Product

The creation of product presentation slides using PowerPoint was implemented in order to ensure that students acquire the knowledge and information required to use computers. Students created slides presenting products in which they were interested, inserting animation and recording narration. This class combined evaluation and revision activities and implemented active learning and, along with enhancing computer skills, awareness relating to a variety of skills required for problem solving were enhanced in an attempt to cultivate independent thinking skills. In particular, the aim was not only to enhance PowerPoint skills but also to improve expressiveness, planning ability and ability to make proposals. This paper reports on the class to create product presentation slides, its contents and its learning effects.

Support System Developed for a Beginner's Design of Blended Learning Courses and Its Use

In recent years, as e-learning has become increa singly common, blended learning has become widespread. Using this teaching method, lectures and e-learning are combined in higher education ins titutions such as universities. E-learning will tend to be used more in the future. Therefore, blended learning is also highly likely to be widely used and to become more popular. To popularize it further, we dev eloped a support system to enable even a beginner to design blended learning courses. The system includes a function to design blended learning, a function to make distributed document and a function for browsing samples. The first function includes both a lesson-plan-making function and a lesson-development-making function. Using the former, a user can produce weekly plans. Using the latter, a user can produce individual lesson plans. This paper reports the support system for the design of blended learning courses. We had users reply a questionnaire and performed the evaluation.

Trial of a distance learning system using a brain wave sensor

We developed a self-study system using Perl language. To date, no device has been available to observe a human state effectively. However, brain wave sensors have become inexpensive recently, allowing observation of the human state. We analyzed the information effectively; a brain wave sensor for human feedback has become usable. This feedback system can measure a students state of concentration and a state of a motivation. Additionally, students show raised motivation because the system sends a students status. Sensing that motivation, effective methods can be recognized. This report presents our results.
