Factors That Influence The Difficulty Of Problem Solving Items, Dara Ramalingam, Ray Philpot Sep 2015

Factors That Influence The Difficulty Of Problem Solving Items, Dara Ramalingam, Ray Philpot

Ray Philpot

Computer-based assessment of problem solving allows problems of both static and interactive natures to be posed. Examples of static problems are scheduling and logic puzzles in which all relevant information is available to the solver at the outset. Problems of an interactive nature, on the other hand, require exploration of the situation to acquire additional knowledge needed to solve the problem. Examples include discovering how to use an unfamiliar mobile telephone or automatic vending machine. This study used data from the 2011 Field Trial of the PISA 2012 computer-based assessment of problem solving which comprised 34 static and 45 interactive …

Proposal Of A Methodology For Bridge Condition Assessment, Maria Rashidi, Peter Gibson Dec 2012

Proposal Of A Methodology For Bridge Condition Assessment, Maria Rashidi, Peter Gibson

Peter R Gibson

Due to the substantial role of bridges in transportation networks and in accordance with the limited funding for bridge management, remediation strategies have to be prioritised. A conservative bridge assessment will result in unnecessary actions, such as costly bridge strengthening or repairs. On the other hand, any bridge maintenance negligence and delayed actions may lead to heavy future costs or degraded assets. The accuracy of decisions developed by any manager or bridge engineer relies on the accuracy of the bridge condition assessment which emanates from visual inspection. Many bridge rating systems are based on a very subjective procedure and are …

Measuring Learning Through Cross Sectional Testing, Steve Lovett, Jennie Johnson

Management Faculty Publications and Presentations

The measurement of student learning is becoming increasingly important in U.S. higher education. One way to measure learning is through longitudinal testing, but this becomes especially difficult when applied to cumulative learning within programs in situations of low persistence. In particular, many Hispanic Serving Institutions (HSIs) find themselves in such situations. Cross sectional testing is a pragmatic alternative, so long as maturity and selection effects can be estimated. The purpose of this paper is to demonstrate the utility and mechanics of measuring learning through cross sectional testing.

Assessment As A Tool For Learning, Maureen Morris, Anne Porter, David Atherton Griffiths Nov 2012

Assessment As A Tool For Learning, Maureen Morris, Anne Porter, David Atherton Griffiths

Associate Professor Anne Porter

Assessment should provide a catalyst for student learning and for reflective teaching practices. Fundamental to the development of appropriate assessment must be a direct link between what is being taught and what is being learned. Both teacher and student must be able to identify this link. The teacher needs to ensure the relevance and validity of the task in terms of both the instructional process and subject objectives. Student learning results in the construction of new knowledge through a process that assembles personally identified content and skills. Subsequent assessment may be facilitated by classification of learning outcomes. The use of …

Voltage Unbalance Emission Assessment In Radial Power Systems, U Jayatunga, S Perera, P Ciufo Nov 2012

Voltage Unbalance Emission Assessment In Radial Power Systems, U Jayatunga, S Perera, P Ciufo

Associate Professor Sarath Perera

Voltage unbalance (VU) emission assessment is an integral part in the VU-management process where loads are allocated a portion of the unbalance absorption capacity of the power system. The International Electrotechnical Commission Report IEC/TR 61000-3-13:2008 prescribes a VU emission allocation methodology establishing the fact that the VU can arise at the point of common connection (PCC) due to upstream network unbalance and load unbalance. Although this is the case for emission allocation, approaches for post connection emission assessment do not exist except for cases where the load is the only contributor to the VU at the PCC. Such assessment methods …
