Learning by teaching has been extensively studied in education and psychology research. However, there has been relatively less effort in this research avenue in CSCL research. computer supported teaming by teaching, as a genus of CSCL activities, is expected to draw more attention in the future. In this pilot study, we propose a model of computer supported teaming by teaching that involves peer tutors in preparing their instruction notes and teaching their peer tutees verbally. Collaborative teaming is incorporated in our pedagogical design. As an initial investigation and for future improvement of our design, we conducted two experimental trials in a graduate-level course. This paper discusses the design of this model and reports our findings from the experimental trials.

As the power of computational Grids increases, there is a corresponding need for better usability in PSE community. In this paper, we describe our experiences on design of project GridPSi, a Gridenabled PSE for physical simulation, GridPSi provides a rich suite of functions that facilitate the composition of computational scripts to automate physical simulations by design domain-specific templates for a verity of research fields. The generic functionality provided by it includes problem modeling, mesh file conversion, computational script generation, solution scheme specification and access to Grid resources. GridPSi offers a simple interface that is intuitive to users in the human-PSE interactions and ways of thinking. Furthermore, we developed higher-level graphical components named PDE wizards that build upon the core functions to guide users through problem modeling process with minimum effort, By using Unicore as Grid middleware, we are lowering the barriers to entry for users wishing to exploit Grid technologies. © 2005 IEEE.

Bioinformatics nowadays is a very attractive field. Many fascinating biological problems were still unsolved, even after a great amount of diverse genomic sequences have been sequenced for the coming of post genome era. Currently available programs are far from powerful enough to recognize the regulatory signals completely. Researches have looked for various types of patterns around the transcription start site (TSS) and tried to translate those as classification rules;however, they were not always good solutions. In this paper, we proposed a new hybrid learning system to recognize the regulatory elements (i.e., promoter) in deoxyribonucleic acid (DNA) sequences. The proposed hybrid system calculated the distributions of oligo-nucleotides statistics as positional weight matrices which contribute to discriminate promoters from non-promoters. This study can help to locate the expressive regions of DNA, to foretell and to realize the properties, structures, and functions of the proteins that are synthesized starting from the coding region of DNA. The benchmark datasets were evaluated using the leave-one-out method. The experimental results demonstrate that the proposed system has higher accuracy than others. © 2005 IEEE.

It has already been proven that peer tutoring is an effective way to engage students in learning. However, without technology support, it can be difficult to conduct peer tutoring program in a classroom. We propose a system called P3T that supports peer tutoring in one-to-one digital learning environment. P3T facilitates peer tutoring by scaffolding both tutors and tutees to prepare for the tutorial session and facilitating their elaborations during the face-to-face tutoring. An experiment was executed to test if the P3T system can help the activity go more smoothly than those without P3T system. This paper discusses the design of P 3T models and system, and reports what is found in our experiment. © 2005 Asia-Pacific Society for computers in Education.

The era of 1: 1 educational computing environment where each student has one mobile computing device is not far away. When such technology designed for individuals is applied to group learning, several student grouping problems could be encountered. In this paper, three issues are identified to illustrate the vision of the 1:2 educational computing environments. In a 1:2 classroom, besides the mobile devices, students also have their own computing desks, i.e. MatrixDesks, to solve the potential student grouping problems. By putting MatrixDesks together, a small group can form a shared working space with the combined desktops immediately and they can use their own digital pens as the input devices to work on and talk over it. Meanwhile, the students use their mobile devices to handle the related individual tasks. MatrixDesks is a coordination of applying the mobile computing and invisible computing to collaborative learning, which will lead to the accomplishment of 1:2 educational computing environments.

When an embedded system is designed, system performance and power consumption have to be taken carefully into consideration. In this paper, we focus on reducing the number of memory access times in embedded systems to improve performance and save power. We use the locality of running programs to reduce the number of memory accesses in order to save power and maximize the performance of an embedded system. We use shorter code words to encode the instructions that are frequently executed and then pack continuous code words into a pseudo instruction. Once the decompression engine fetches one pseudo instruction, it can extract multiple instructions. Therefore, the number of memory access times can be efficiently reduced because of space locality. However, the number of the most frequently executed instructions is different due to the program size of different applications;that is, the number of memory access times increases when there are less encoded instructions in a pseudo instruction. This situation results in a degradation of system performance and power consumption. To solve this problem, we also propose the use of multiple reference tables. Multiple reference tables will result in the most frequently executed instructions having shorter encoded code words, thereby improving the performance and power of an embedded system. From our simulation results, our method reduces the memory access frequency by about 60% when a reference table with 256 instructions is used. In addition, when two referen%ce tables that contain 256 instructions each are used, the memory access ratio is 10.69% less than the ratio resulting from one reference table with 512 instructions.

One-on-one educational computing refers to I student I computing device, which means every student in a group uses a digital learning device. In this paper, we present a model of student question generation called AGQ, which stands for "asking a good question," supported by one-on-one educational computing in the classroom settings. AGQ is designed for engaging students in a challenging learning activity that potentially involves higher-level cognitive processing operations. We shall describe the general design of AGQ, called Product Evolution, and that the current version is a variation of it.

Designing component-based application that meets performance requirements remains a challenging problem, and usually requires a prototype to be constructed to benchmark performance. Building a custom benchmark suite is however costly and tedious. This demonstration illustrates an approach for generating customized component-based benchmark applications using a Model Driven Architecture (MDA) approach. All the platform related plumbing and basic performance testing routines are encapsulated in MDA generation "cartridges"along with default implementations of testing logic. We will show how to use a tailored version of the UML 2.0 Testing Profile to model a customized load testing client. The performance configuration (such as transaction mix and spiking simulations) can also be modeled using the UML model. Executing the generated deployable code will collect the performance testing data automatically. The tool implementation is based on a widely used open source MDA framework AndroMDA. We extended it by providing a cartridge for a performance testing tailored version of the UML 2.0 Testing Profile. Essentially, we use OO-based meta-modeling in designing and implementing a lightweight performance testing domain specific language with supporting infrastructure on top of the existing UML testing standard. © 2005 ACM.
