Tests as Security Valves Backwash Effect on Course Syllabus

Tests as Security Valves: Backwash Effect on Course Syllabus The six stages of Brown’s curriculum design are specified as needs analysis, objectives, testing, materials design, instruction and evaluation (1995). Testing is before materials design and instruction because in this way, the program is not run by the materials and instruction, and objectives identified through needs analysis are in the foreground. Testing serves as “a security valve” for the program. This case study illustrates how tests function as a security valve in programs. As the researchers carried out a program evaluation study in ENG 311 Advanced Communication Skills course offered by the Department of Modern Languages in Middle East Technical University, Ankara, Turkey, they discovered the conflict between the course coordinator, test writers, course instructors and students in relation to the exam content. Validity and reliability concerns were constantly raised in the meetings.The study data was collected from a variety of sources including the course syllabus, test specifications, meeting minutes, classroom observations, student questionnaire and focus group interview. Analysing the data, the researchers prepared a validity and reliability frame. This frame revealed that the course syllabus was in need of revision.In this presentation, the participants will learn how problems in the test revealed the underlying problems in the syllabus design. The validity and reliability frame and suggestions the researchers made for the course coordinator and test writers will be shared.


Performance Analysis of a Micro-scale Model Helicopter Rotor in Hover Flight
Şahin, Mustafa; Kurtuluş, Dilek Funda (2015-09-12)
This experimental study contains the design, production, test and evaluation of the test processes of a Micro-Scale Rotor Test-Rig. For the study, NACA 0012 airfoil section is selected as a rotor blade without a twist and a taper ratio. The tests cover the thrust and the torque relation with different blade pitch angles and RPM values.
Joint shear strength prediction for reinforced concrete beam-to-column connections
Unal, Mehmet; Burak Bakır, Burcu (2012-02-10)
In this analytical study numerous prior experimental studies on reinforced concrete beam-to-column connections subjected to cyclic loading are investigated and a database of geometric properties, material strengths, configuration details and test results of subassemblies is established. Considering previous experimental research and employing statistical correlation method, parameters affecting joint shear capacity are determined. Afterwards, an equation to predict the joint shear strength is formed based o...
Development of test structures and methods for characterization of MEMS materials
Yıldırım, Ender; Arıkan, Mehmet Ali Sahir; Department of Mechanical Engineering (2005)
This study concerns with the testing methods for mechanical characterization at micron scale. The need for the study arises from the fact that the mechanical properties of materials at micron scale differ compared to their bulk counterparts, depending on the microfabrication method involved. Various test structures are designed according to the criteria specified in this thesis, and tested for this purpose in micron scale. Static and fatigue properties of the materials are aimed to be extracted through the ...
Environmental applications of hyperspectral anomaly and target detection algorithms
Soydan, Hilal; Karpuz, Celal; Department of Mining Engineering (2017)
The objective of this thesis study is to understand the capacity of hyperspectral anomaly detection and target detection algorithms for contamination mapping, with a focus on developing a new methodology for environmental problems related to coal mining operations. Considering the data availability, specific chemical structure and reflectance properties as well as being one of the common contaminants in mining operations, hydrocarbon induced problems are studied for water and soil medium separately. Having ...
A new contact & slip model for tracked vehicle transient dynamics on hard ground
Ozdemir, Mehmet Nuri; Kilic, Varlik; Ünlüsoy, Yavuz Samim (2017-10-01)
This study presents a new general transient contact and slip model for tracked vehicles on hard ground which is simple, accurate, and in agreement with the test results to a satisfactory level. Simulating zero track speed instances become possible with the new contact/shear model which is the major proposed improvement in addition to more accurate results for transient steering and tractive inputs. The model represents a general tracked vehicle having rear or front sprockets, with parameters for center of g...
