PBL Framework for Enhancing Software Development Skills: An Empirical Study for Information Technology Students

According to the shortage of personnel and new entry employees lacking qualification in the ICT industry, the Information Technology School at Mae FahLuang University have designed and implemented the PBL framework to enhance the software development skills for students. The PBL framework integrates the three courses project to a one problem domain. By the end of the semester, we have assessed the result of applying the PBL framework. The developed framework is evaluated into two aspects including the ability to enhance learning efficiency for the courses content and the ability of professional skills for students. The professional skills in this paper consist of motivation, self-directed learning, collaborative learning, and communication respectively.     

Designing and managing virtual learning communities

There is a tendency to view education on the Internet as simply a more efficient way to access information and to communicate, but the Internet is much more than just another tool. The Internet has the potential to create communities where students participate in robust discourse and rituals of communication, establish their identities, and traverse community boundaries. We believe we need to design on-line courses with sound pedagogical frameworks and with a sense of promoting community values of diversity, connectedness, and civic responsibility. Therefore, the purpose of this paper is to describe a framework that we use to design virtual learning communities. We explain community activities to consider, describe how we used our framework for designing three classes, and pose issues that arose when using this framework. We hope our thoughts will direct discussion toward the creation of innovative learning communities

Using Computer-Mediated Peer Review in an Engineering Design Course

Writing, especially when accompanied by feedback and revision, is a powerful enhancer for learning, as the writing-to-learn literature attests. Yet, writing as a vehicle for learning seldom appears in engineering content courses. We relate our experiences with a pilot program in engineering design funded through the National Science Foundation. Specifically, we focus on using Calibrated Peer Review as a platform for formative and summative assessment of integrated writing assignments in targeted courses. Our results show that students improved their skills in elements of engineering design and in writing. Additionally, assessment of the learning outcomes from the targeted courses were used successfully to document Accreditation Board for Engineering and Technology's criterion EC3 (g), “ability to communicate effectively,” in our latest accreditation cycle.      

Audience awareness: leveraging problem-based learning to teach workplace communication practices

Research on the transition from school to work suggests that students entering the workplace struggle to adapt their writing and speaking to individual audiences. To address this problem, the article presents principles for using problem-based learning to design assignments that teach students to tailor communication to the needs of audiences. The approach focuses not on specific workplace documents but on the higher order workplace practice of effectively connecting documents and presentations to audience needs, and designing communication accordingly. A two-year study of capstone design courses suggests that the approach encourages students to explicitly consider audience needs when composing.     

Public policy and technical communication across the curriculum atthe Colorado School of Mines

Many engineering students are unprepared to address public policy issues because their education is fragmented: they tend to focus narrowly on technical solutions to closed-end problems in engineering and science courses, and they do not see how technical communication relates to either engineering or public policy. A multidisciplinary approach to professional communication which addresses this fragmentation is discussed. In the four-semester engineering practices introductory course sequence (EPICS) program, students learn professional communication skills by working in groups on `real world' projects for which industry and government professionals serve as clients. These open-ended problems involve numerous nontechnical constraints, including a variety of public policy issues. Communication skills and the important connections among competent technical analysis, effective communication, and effective policy formation are reinforced and extended in the policy analysis course and senior design sequence, where students are required to consider and articulate the public policy implications of complex technological projects

A project-based approach to teaching research writing to nonnative writers

It is commonly accepted that writing instruction should meet the specific needs of writers and that students in scientific and technical fields benefit more by learning to write to match the requirements of their specific fields. A variety of models for writing classes have been proposed to meet these needs, from genre-based approaches to courses targeting specific disciplines to general courses serving a heterogeneous group of students from many disciplines. Although persuasive arguments can be made for discipline-specific writing courses, many writing courses for nonnative writers at U.S. universities operate with two key constraints. First, monetary and curricular limitations mean that students from a variety of disciplines are placed in the same course. Second, these courses are staffed by instructors who, while well-prepared in addressing language needs of nonnative writers, may know very little about the content and conventions of engineering and science. This paper discusses a writing course which works within these constraints and has been developed for graduate students who are early in their program of study. In the course, groups of students carry out an original research project as a vehicle to learn professional writing conventions common to research papers in a variety of scientific and engineering fields. In addition, students analyze written conventions in published articles within their fields to raise awareness of how general conventions are worked out in their individual disciplines. General principles for the course are discussed, and samples of successful research topics are provided.

MEMIS: A Mobile-Supported English-Medium Instruction System

Education is one of the most important elements in our lives, as it provides a direct gain in knowledge. Thus, in order to provide better academic achievement, more and more instructors are adapting collaborative learning to their classes. However, two major problems lurk behind collaborative learning. First, it is difficult to apply collaborative learning because students tend to engage passively with traditional lectures. As a result, interactive technologies such as clickers have been applied to increase interactive learning and raise the rate of interaction. Nevertheless, these interactive technologies still have some limitations, such as limited mobility, high costs, setup issues, technical difficulties, and little support of higher-order thinking skills. Second, recently there has been an increasing number of EMI (English as Medium of Instruction) courses added to university course offerings in countries where English is not the first language. The goal of these courses is to support university internationalization and address the global status of English. However, it is even harder to achieve in-class interaction in large EMI lecture courses. In addition, some studies argue that EMI courses might affect the overall learning of course content because of students’ poor lecture comprehension and passive engagement in class.In order to address the limitations of interactive technologies, encourage more collaborative learning, facilitate greater in-class interaction in large lecture courses, and resolve students’ poor lecture comprehension in EMI courses, the author introduces MEMIS (Mobile-Supported English-Medium Instruction System), which includes both a T&S (Teachers & Students) mobile app and an EMI pedagogical method. The author first provides detailed implementation and all the features of the T&S mobile app, which improves students’ perceptions of classroom participation and in-class interaction. Then the author explains how she develops her EMI pedagogy such that it utilizes the features of the T&S mobile app to: 1) increase students’ overall learning in her EMI course, 2) develop students’ construction of knowledge and higher-order thinking, and 3) achieve all six cognitive processes from Bloom’s revised taxonomy. The author adapts a quasi-experimental design, statistically analyzes the effectiveness of both exam scores and final grades between a control group and an experimental group, and then asks students to evaluate their experiences and provide feedback about MEMIS. Based on both statistical results and students’ overall feedback, the author confirms that MEMIS is an effective approach that improves lecture comprehension, encourages more class engagement, promotes collaborative learning, and achieves better learning outcomes.     

From academic writing to job-related writing: achieving a smoothtransition

Do university writing experiences prepare students for future job-related writing tasks? If not, how can we create a smoother transition from the academy to the workplace? The author analyzes the differing discourse communities of academic writing and technical communication which may limit the transfer of skills from one arena to the next. The discussion considers the ways process, collaborative learning, writing across the curriculum, and language theories can form the foundation for constructive communication among disciplines. As the focus of academic writing moves from an emphasis on the individual to social context and wider audiences, it bridges the gap between disciplines and can ease the movement from the classroom to real-world settings     

Preparing technical communication students to play a role on the translation team

Technical communicators need to be prepared for the challenges of international communication. This tutorial focuses on the need for technical communication faculty to prepare students to be skilled intercultural communicators and to play a role on the translation team. The tutorial begins with a discussion of the importance of writing for translation in the international workplace and then presents specific assignments designed to instruct students in intercultural communication and give them experience writing for translation. In addition to introducing students to the cultural issues that impact the creation of documentation for international audiences, these assignments also serve to reinforce core skills recognized as vital to professional success in the field of technical communication. Taken together, these assignments can be used as the basis for a course in international technical communication. An appendix to the tutorial includes numerous resources available to faculty who want either to develop a course in international technical communication or to include some of the assignments in existing technical communication courses.

Hardware-accelerated design space exploration framework for communication systems

The efficient hardware implementation of signal processing algorithms requires a rigid characterization of the interdependencies between system parameters and hardware costs. Pure software simulation of bit-true implementations of algorithms with high computational complexity is prohibitive because of the excessive runtime. Therefore, we present a field-programmable gate array (FPGA) based hybrid hardware-in-the-loop design space exploration (DSE) framework combining high-level tools (e.g. MATLAB, C++) with a System-on-Chip (SoC) template mapped on FPGA-based emulation systems. This combination significantly accelerates the design process and characterization of highly optimized hardware modules. Furthermore, the approach helps to quantify the interdependencies between system parameters and hardware costs. The achievable emulation speedup using bit-true hardware modules is a key enabling the optimization of complex signal processing systems using Monte Carlo approaches which are infeasible for pure software simulation due to the large required stimuli sets. The framework supports a divide-and-conquer approach through a flexible partitioning of complex algorithms across the system resources on different layers of abstraction. This facilitates to efficiently split the design process among different teams. The presented framework comprises a generic state of the art SoC infrastructure template, a transparent communication layer including MATLAB and hardware interfaces, module wrappers and DSE facilities. The hardware template is synthesizable for a variety of FPGA-based platforms. Implementation and DSE results for two case studies from the different application fields of synthetic aperture radar image processing and interference alignment in communication systems are presented.
