Distributed Education and the Role of Online Learning in Training Professional Psychologists.

Distributed learning and its allied concept, distance education, have the potential to move graduate training beyond the physical classroom, providing "anytime" and "anyplace" educational opportunities to new groups of learners as well as to students in traditional campus-based programs. It is argued that the focus on online learning activities found in distributed learning institutions is most compatible with a model of pedagogy that emphasizes, among other things, asynchronous small group discussions, collaborative problem solving, reflective inquiry, competency-based outcomes, and the facilitator role of the instructor. The article concludes with suggestions for and challenges regarding the application of computer-based learning tools to the training of clinical psychologists.

Practical Summer Training in Civil and Construction Engineering for Cultivation of Professional Ability

The cultivation of professional ability for undergraduate civil and construction engineering students is very important to help them meet the challenges that await them in the fast changing world. This paper presents a thorough study of practical training in the field of civil and construction engineering. Based upon an extensive literature review of the practical training curriculum worldwide, questionnaires were provided to contractors, educators and students in Taiwan to assess problems in traditional summer practical training courses for civil and construction engineering in Taiwan. At the outset of the study, it was thought that the lack of available jobs for students might be related solely to the economy but the findings indicated that the reasons were more complex ranging from concerns about liability for students working in construction sites to traditional cultural concerns about whether apprentices should be paid. The Delphi method was used to study the problems that were identified, relating to planning, execution, evaluation, and development of the existing practical training programs. A refined and improved summer practical training curriculum is proposed for civil and construction engineering education in Taiwan based upon the findings. Although the survey related to practical training programs for engineering students was conducted in Taiwan, the results might vary in other countries. The procedures used, and results obtained may be valuable resources and have a potential use for other countries. What is certain is that practical training can play an important role in readying engineering students for the work place in any location and making the practical training as effective and as safe as possible should be a universal goal.     

Tradition and Innovation in Teaching Structural Design in Civil Engineering

This paper briefly reviews the history of structural engineering education: The dawn, development, and consolidation of traditional education systems, as well as their fall into decline in the contemporary technological world. Recent graduates in civil engineering do not have all of the skills and knowledge that the labor market is demanding and civil engineering is losing the social prestige and professional recognition that our profession deserves. It is necessary to improve traditional education systems to produce the best civil engineers. The writers present a detailed discussion of their experiences teaching structural design at the School of Civil Engineering of Ciudad Real, Spain, using project-based and cooperative learning methods, as well as implementing knowledge management and transference to the learning process. Results and costs of these methods, as well as the problems related to faculty selection, are set out. The paper concludes with a reflection on the major educational possibilities and historical opportunities presented through the introduction of these new methods and suggest that this is the best way to combine engineering education and practice.

Teaching Evaluations for Construction Engineering and Management: Opportunity to Move Us Forward

Engineering education is challenged to usher in new approaches to preparing its students for their professional careers. Many blue-ribbon committees call for systematic modifications in research universities to clear the path for cross-disciplinary learning communities. In this context, the paper investigates the effect of student ratings as a measure of teaching effectiveness. One survey found that engineering sophomores perceive active student-centered teaching methods as greatly ineffective, while a second survey highlighted that lecture-based teaching underpins student rating forms used at U.S. research universities. With the goal of aligning teaching objectives, learning outcomes, and the criteria for evaluating teaching, a student rating form is presented. The scales of the multidimensional construct are based on the most up-to-date understanding of effective pedagogy, the new American Accreditation Board for Engineering and Technology criteria, and a view of the future of our profession. The importance of this paper lies in its science-based proposal underlying a call for the establishment of a coalition to validate a constructive approach to further teaching performance in the field of construction engineering and management.     

Intelligent Adaptive Cyber-Physical Ecosystem for Aerospace Engineering Education, Training, and Accelerated Workforce Development

Transformative changes are on the horizon in aerospace engineering education and learning in general. These changes are attributable, in part, to the developments of a number of aerospace, learning and other leading-edge technologies and their synergistic combinations and convergence. The related technologies include ubiquitous, cloud, and petascale/exascale computing; ultrahigh-bandwidth networks; pervasive wireless communication; intelligent autonomous robotics; artificial general intelligence; powerful game engines and facilities; networked immersive virtual environments and virtual worlds; augmented and enhanced reality; and novel human-technology interfaces. This paper describes some of the frontiers of, and challenges in, future aerospace systems and the drivers for transformative changes in aerospace engineering education. The need to have a holistic perspective and a comprehensive approach for aerospace education, research, training, and accelerated workforce development is outlined. A starting point to accomplish this task is the development of an intelligent adaptive cyber-physical ecosystem for the aerospace workforce. The continuously expanding major components of the ecosystem include integrated knowledge discovery and exploitation facilities; novel agent-supported visual simulations (with cognitive learning and understanding abilities); immersive three-dimensional (3D) virtual world facilities; intelligent, multimodal and humanlike interfaces; and smart mobile wireless devices. The ecosystem will provide timely, engaging, personalized/collaborative, and tailored visual learning. It will stimulate creativity and innovation and prepare the learners to work in future global virtual collaborative enterprises and become leaders in a world of growing complexity.

MgO Saturation in Secondary Metallurgical Lime‐aluminate and Lime‐silicate Slags

This paper provides an informative basis on MgO saturation in secondary metallurgical slags by conducting thermo‐chemical calculations in the ternary base system Al₂O₃‐CaO‐SiO₂ at 1600 °C, 1650 °C and 1700 °C using FactSage^TM6.0. The results for lime‐aluminate and lime‐silicate slag are displayed in a straightforward and illustrative manner. In addition, approximate equations describe the temperature dependencies: a temperature rise of 50 °C increases the MgO saturation limit by about 1 wt. %.     

Numerical Simulation of Turbulent Flows,Heat and Mass Transfer in Metallurgical Induction Processes

Comprehensive knowledge of the turbulent flows, heat and mass transfer processes in the melt of induction applications is required to realize efficient metallurgical processes. Experimental and numerical studies of the melt flow in induction furnaces show that the flow pattern, which comprises several vortices of the mean flow, and the temperature distribution in the melt are significantly influenced by low‐frequency large‐scale flow oscillations. Two‐ and three‐dimensional hydrodynamic calculations of the melt flow, using two‐equation turbulence models based on Reynolds Averaged Navier‐Stokes approach, do not predict the large‐scale periodic flow instabilities obtained from the experimental data. That is why the Large Eddy Simulation (LES) numerical technique was approved to be an alternative for the various k‐? model modifications. The results of the transient 3D LES simulation of the turbulent melt flow revealed the large‐scale periodic flow instabilities and the temperature distribution in the melt, which both are in good agreement with the expectations based on the data from the experiments. The studies, presented in this paper, demonstrate the possibility of using the three‐dimensional transient LES approach for successful simulation of heat and mass transfer processes in metallurgical applications.     

Predicting the Academic Performance of Construction Engineering Students by Teaching and Learning Approaches: Case Study

There are various teaching approaches that instructors may adopt in their quest to teach effectively, and students can choose from a range of learning approaches to help them achieve good grades. This study investigates the effectiveness of personal learning approaches adopted by undergraduates and the teaching approaches employed by instructors in the context of construction engineering courses. The research questions are as follows. (1)?What are the students’ learning approaches that lead to better academic achievement? (2)?What are the instructors’ teaching approaches that give rise to better academic achievement? The study also aims to construct a model to predict a student’s likely academic performance in a construction engineering course. The research design is a self-administered survey. Using a structured questionnaire consisting of questions relating to learning strategies and teaching approaches, data were collected from undergraduates who majored in construction engineering. Statistical analyses undertaken include Pearson correlation and multiple linear regression modeling. Pearson correlation analysis shows that both the Growing Teaching approach and the students’ Achieving Motive learning approach are significantly correlated with academic performance. A robust grade prediction model was developed, whereby a student’s grade in a construction engineering course may be predicted using one teaching approach (Growing Teaching) and three learning approaches (Achieving Motive, Achieving Strategy, and Deep Motive). To help students obtain higher grades in a construction engineering course, instructors should adopt the Growing Teaching approach, and students should adopt the Achieving Motive learning approach. Because students who adopt the Deep Motive learning approach are penalized with lower grades, it is recommended that instructors modify their teaching methods and approaches so that students do not take shortcuts in their learning without deeper regard for higher-order learning outcomes.     

Using the Computer to Develop a Better Understanding in Teaching Structural Engineering Behavior to Undergraduates

A parallel approach to the traditional method of teaching of Structural Engineering, which is based on the use of the computer, is presented in this paper. In this approach the emphasis has been shifted to developing a better understanding of the behavior of structures for which the computer plays an important role. The authors believe that the introduction of suitable methodologies for the validation of computer results and the utilization of the power of computers to facilitate a better understanding should be essential in teaching engineering students. The reflective use of computers can facilitate achieving this goal. The paper gives examples of the authors’ achievements in encouraging the interactive use of the computer in developing a different way of understanding structural behavior in undergraduate teaching, through a problem based and student centered learning approach. The paper shows how a different approach, using computers to model real world problems, can allow students to widely explore the design space and very quickly acquire a better understanding, which has traditionally been the domain of the experienced engineer. In this paper, examples of the students’ work, which demonstrates this approach is presented. Although examples presented in this paper are based on students’ work, the approach and methodologies highlighted can be equally beneficial to both graduate and experienced engineers and to the construction industry as a whole.
