Development of parallel cloze tests using cohesion

My thesis is simple: cohesion, the interdependence of textual elements, can be used to build reliable doze tests. Furthermore, reliable doze tests built using cohesion are parallel. This paper seeks to explore those hypotheses, and point out why the issues surrounding them are important. Developing good language tests is difficult. Tests must be both reliable and valid for their interpretations and uses. To be reliable, the potential sources of error in the test itself must be minimized. Reliability is affected by not only the examinee\u27s language ability, but also by test methods, attributes of the test taker not related to the language abilities we want to measure, and random factors. Ideally, only the language abilities that we want to measure are reflected by the test scores, but in practice, this is not the case. Unfamiliarity with a test method, or dislike of a test method, affects the examinee\u27s performance. A test on listening, for example, should not depend on a student\u27s ability to comprehend complex written instructions. Finally, random factors such as lighting, what a test taker had for breakfast, or the temperature in the testing environment can have an effect on scores. In order for a test to be reliable, these influences must be minimized

HEV to PHEV Conversion Compatibility

This paper includes some of the information gathered regarding the feasibility of converting a series-parallel configured electric vehicle to a plug-in hybrid electric vehicle versus using a series configured electric vehicle to a plug-in hybrid electric vehicle. It will explain the theory behind how a series configured hybrid electric vehicle (HEV) might be a better option due to the power rating of the electric motor. Using ADVISOR (Advanced Vehicle Simulator) it will explain test results and form conclusions regarding the efficiency of a series-parallel configured HEV vs. a series configured HEV as it relates to their feasibility of conversion to a plug-in hybrid electric vehicle (PHEV)

Paired Programming in a Clayton’s Capstone Project Course

In this paper the authors describe an Information Systems course where paired programming was trialled in the hope of improving both the assessment outcomes and the resourcing of an existing systems design course which incorporated a capstone project. The authors found that it did offer a significant improvement, but the improvements did not match the predicted outcomes, with a number of weaknesses to the model being highlighted. In particular, it was found that paired programming did not reduce teaching load when the group size was reduced
