Assessing Technological Literacy of Middle School Students

Project Lead the Way (PLTW) is a rigorous and relevant pre-engineering curriculum implemented in middle schools and high schools throughout the United States. PLTW has a hands-on approach using activities and project-based learning. The College of Engineering at Wichita State University has partnered with three local school districts to implement the PLTW program to increase interest in Science, Technology, Engineering and Mathematics (STEM). This study begins to assess the impact of the PLTW program on student perceptions and attitudes toward engineering and technology as part of an ongoing three-year assessment. A pre- and post-assessment were administered to middle school students (N=1063 and N=800, respectively) at the beginning and end of the 2010-2011 academic school year. The assessment consisted of 67-questions addressing students’ attitudes toward engineering and technology. This assessment was a combination of subscales from the Pupils’ Attitude Toward Technology (PATT-USA) and the Middle School Attitudes to Engineering, Science & Mathematics survey. Dependent variables of interest included attitude differences between PLTW students and nonPLTW students, gender differences, and differences attributed to length of involvement in the PLTW program. Results indicated PLTW students have a greater interest in technology, however there were notable gender differences and differences attributed to length of involvement in the program. Males had a greater interest in technology and longer involvement (0-3 years) in the program resulting in more positive attitudes. Females tended to have more negative opinions about technology at both pre- and post-assessment

The social value of a QALY : raising the bar or barring the raise?

Background: Since the inception of the National Institute for Health and Clinical Excellence (NICE) in England, there have been questions about the empirical basis for the cost-per-QALY threshold used by NICE and whether QALYs gained by different beneficiaries of health care should be weighted equally. The Social Value of a QALY (SVQ) project, reported in this paper, was commissioned to address these two questions. The results of SVQ were released during a time of considerable debate about the NICE threshold, and authors with differing perspectives have drawn on the SVQ results to support their cases. As these discussions continue, and given the selective use of results by those involved, it is important, therefore, not only to present a summary overview of SVQ, but also for those who conducted the research to contribute to the debate as to its implications for NICE. Discussion: The issue of the threshold was addressed in two ways: first, by combining, via a set of models, the current UK Value of a Prevented Fatality (used in transport policy) with data on fatality age, life expectancy and age-related quality of life; and, second, via a survey designed to test the feasibility of combining respondents’ answers to willingness to pay and health state utility questions to arrive at values of a QALY. Modelling resulted in values of £10,000-£70,000 per QALY. Via survey research, most methods of aggregating the data resulted in values of a QALY of £18,000-£40,000, although others resulted in implausibly high values. An additional survey, addressing the issue of weighting QALYs, used two methods, one indicating that QALYs should not be weighted and the other that greater weight could be given to QALYs gained by some groups. Summary: Although we conducted only a feasibility study and a modelling exercise, neither present compelling evidence for moving the NICE threshold up or down. Some preliminary evidence would indicate it could be moved up for some types of QALY and down for others. While many members of the public appear to be open to the possibility of using somewhat different QALY weights for different groups of beneficiaries, we do not yet have any secure evidence base for introducing such a system

Examination of Dual vs. Single Monitor Use During Common Office Tasks

Previous studies have found that using multiple monitors increases productivity, but there are also documented drawbacks to increased monitor count and/or size. The purpose of this study was to determine whether increases in productivity hold true with newer technology, like wide flat-screens, in the multitasking context. Sixty participants were asked to complete several tasks commonly completed in an office environment. These tasks were performed on four different monitor configurations: a single and dual 17” monitor(s) and single and dual 22” monitor(s). Participants located information from several documents and compiled this information into a new document. Dependent variables measured included efficiency, effectiveness, and satisfaction. Results indicated a performance benefit for dual monitor usage, regardless of monitor size. Participants most preferred using dual 22 monitors and least preferred a single 17 monitor
