Effective Teaching And Active Learning Of Engineering Courses With Workbook Strategy, Yasar Demirel
Effective Teaching And Active Learning Of Engineering Courses With Workbook Strategy, Yasar Demirel
YASAR DEMIREL
Often mismatches between learning and teaching styles arise because students are in majority visual and sensing learners, and most instructors are intuitive and reflective learners. Beside that, textbooks also have their own styles, and their contents, depth of coverage of materials, and organization may affect the teaching and learning environment. Instructor, as the primary selector of the textbook, has the responsibility in providing students with effective teaching strategy. Here, we present a new strategy called the ‘workbook strategy,” which integrates these four elements: (i) classroom analysis, (ii) use of workbook beside textbook, (iii) group work, and (iv) use of ‘blackboard’ …

Coupling refers to a flux occurring without its primary thermodynamic driving force; for example, mass flux without a concentration gradient called the thermal diffusion is a well-known coupled process. Coupling also refers to a flux occurring in a direction opposite to the direction imposed by its driving force; for example, a mass flux can occur from a low to a high concentration region and is called the active transport or uphill transport, such as potassium and sodium pumps coupled to chemical energy released by the hydrolysis of adenosine triphosphate (ATP) in biological systems.

Society expects that a modern college education will turn out students who are analytical, intellectually curious, culturally aware, employable, and capable of leadership. Some important skills needed for all degree programs are problem solving, communication (written and oral), team or group work, learning, and information processing and technology. Instructors feel rewarded and satisfied when they sense that they have made a difference in the life of a student.

Nonequilibrium Thermodynamics In Engineering And Science, Yasar Demirel, S.I. Sandler

The field of nonequilibrium thermodynamics has been a popular one outside the United States, especially in Europe, and scientists there from various disciplines have published extensively on the use of nonequilibrium thermodynamics in a large variety of biological, chemical, and mechanical engineering applications. In contrast, the number of publications from North America has been relatively modest. Here, we review the field of nonequilibrium thermodynamics to assess its utility and impact in engineering and science. We find that developments in the fields thermodynamic optimality of processes, dissipative structures, coupled transport and rate processes, and biological systems suggest that in some circumstances …

Mismatches between the learning and teaching styles are common because students are in majority visual and sensing learners, yet most instructors are intuitive and reflective learners. Beside that, textbooks also have their own styles, and their contents, depth of coverage of materials, and organization may affect the teaching and learning. For reducing the mismatches, and achieving effective teaching and active learning, we present ‘workbook strategy,” which integrates the following four elements: (i) classroom analysis, (ii) use of workbook beside textbook, (iii) group work, and (iv) use of ‘blackboard’ as information technology. The workbook strategy provides all the essential verbal and …

Exergy-Based Performance Analysis Of Packed-Bed Solar Air Heaters, Yasar Demirel, H.H. Ozturk
Exergy-Based Performance Analysis Of Packed-Bed Solar Air Heaters, Yasar Demirel, H.H. Ozturk

This paper presents an experimental investigation of the thermal performance of a solar air heater having its flow channel packed with Raschig rings. The packing improves the heat transfer from the plate to the air flow underneath. The dimensions of the heater are 0.9m wide and 1.9m long. The aluminium-based absorber plate was coated with ordinary black paint. The characteristic diameter of the Raschig rings, made of black polyvinyl chloride (PVC) tube, is 50mm and the depth of the packed-bed in flow channel is 60 mm. Energy and exergy analyses were applied for evaluating the efficiency of the packed-bed solar …
