Improving design project experiences through improved assessment practices.

This paper is offered as an introduction to the ways in which improved foci on educational outcomes associated with engineering design project experiences may lead to: (a) improvements in the learning of engineering students and consequently, (b) improved knowledge, design and technology to benefit individuals in need. Strategies to improve learning outcomes of design experiences include clearly articulating what it is that we want students to know and achieve, having detailed means of assessing each of the learning outcomes we target, communicating about the assessment process with students from the start of their design experiences, and providing thorough evaluative feedback to students to foster learning while we still have access to them. This paper is based on ongoing work within the National Science Foundation (NSF) Senior Design Projects to Aid Persons with Disabilities program. Readers are invited to collaborate in further efforts in this area.

Practice and list effects on the synthetic sentence identification test in young and elderly listeners.

A high prevalence of central auditory processing disorders (CAPD) has been reported in the elderly based on scores for the Synthetic Sentence Identification Test (SSI). This study examined practice effects and list differences on the Auditec version of the SSI with an ipsilateral competing message in 30 young and 20 elderly participants. Results for the younger participants suggested that a minimum of one practice list should be used with the SSI, whereas results for the elderly participants suggested that a minimum of three practice lists should be used. The binomial model of A. R. Thornton and M. J. M. Raffin (1978) was suggested for use in determining the required number of lists needed to obtain reliable SSI performance. Significant list differences were found with the Auditec version of the SSI. It was recommended to use only Lists A, C, D, E, G, and I for consistent results across lists. Practice effects and list differences should be accounted for when using the SSI for the assessment of CAPD in elderly and young listeners.

Using a multidisciplinary team approach in biomedical engineering senior design.

Under Criterion 4, the Professional Component of the Accreditation Board for Engineering and Technology (ABET) Engineering Criteria 2000, a curriculum culminating in a major design experience is required. In addition, under Criterion 3, program graduates must demonstrate an ability to function on multidisciplinary teams. This paper describes some team related issues in senior design at University of Connecticut (UConn) with National Science Foundation (NSF) Senior Design Projects to Aid Persons with Disabilities and industry-sponsored projects. While these Criteria can both be satisfied in a senior design course sequence, it is not the most desirable method to achieve satisfactory results. Effective teamwork involves skills that may be learned in classes and training sessions. It is best achieved through team experiences in a series of courses, ideally beginning the freshman year.

Technological applications in the assessment of acquired neurogenic communication and swallowing disorders in adults.

The role of technology is expanding rapidly in many aspects of the diagnostic process with patients who have neurogenic communication and swallowing disorders. In this article we discuss a broad selection of technological tools that enhance a wide range of diagnostic tasks, such as taking case histories, administering and scoring tests, performing acoustic, physiologic, cognitive, and linguistic analyses, making normative comparisons, profiling diagnostic results, and making diagnostic decisions. Clinicians are encouraged to scrutinize the relative value of all diagnostic tools to maintaining the quality of service. An appendix includes information for contacting vendors and manufacturers of the products discussed.

Technological applications in the treatment of acquired neurogenic communication and swallowing disorders in adults.

Clinicians can use the computer as an effective clinical tool by incorporating what is known about neurogenic communications disorders, treatment, and technology. Computers can be used to administer activities designed by clinicians, vary stimulus characteristics, adjust response requirements, present cues, and select tasks, all in response to patient performance. Specialized devices can be used to measure small physiologic changes, help patients communicate with and control their environment, and allow clinicians to view closely what we could only imagine only a few years ago. Users of technology must focus not only on effectiveness and operational efficiency, but also ensure an optimal quality of treatment. This article reviews many of the ways technology is used in the treatment of people suffering from neurogenic communication and swallowing problems.

First year experience at the University of Connecticut with NSF design projects to aid persons with disabilities.

This paper provides an overview of the first year experience at University of Connecticut (UConn) with National Science Foundation (NSF) Senior Design Projects to Aid Persons with Disabilities. Devices and software to aid persons with disabilities often need custom modification, are prohibitively expensive, or even nonexistent. Much of the disabled community does not have access to custom modification of available devices, and other benefits of current technology. Moreover, when available, engineering and support salaries make the cost of any custom modifications beyond the reach of most disabled individuals. The NSF in 1988 started to provide a mechanism whereby student engineers at universities throughout the United States designed and constructed devices for persons with disabilities. This program combined the academic requirement of a design experience with enhanced educational opportunities for students, and improved the quality of life for disabled individuals. Students and university faculty provided, through their normal ABET accredited senior design class, engineering time to design and build the device or software, and the NSF provided funds, competitively awarded to universities, for supplies, equipment and fabrication costs for the design projects. Described in this report are first year experiences at UConn with this NSF program including lecture topics, site visits to clients and project selection, required reports and the WWW, course structure and organization.

Magnitude estimation scaling of annoyance in response to rock music: effects of sex and listeners' preference.

The present study parallels an earlier one Fucci, Petrosino, and Banks in 1994 concerned with sex and listeners' preference effects on magnitude estimation scaling of rock music. The difference between the two studies is that the subjects in 1994 were asked to scale "loudness" while the present subjects were asked to scale "annoyance." The prior results and those of the present study were different, i.e., the women's preference appeared influential in the magnitude estimation scaling of rock music previously but here the men's preference appeared influential. If subjects are instructed to judge the annoyance of an auditory signal, they may respond differently than if asked to judge its loudness. Judgments of annoyance appear to be more context dependent whereas loudness judgments may reflect a perceptual process more closely related to physical aspects of the signal.

Linguistic aspects of magnitude-estimation scaling of instrumental music, instrumental music with vocal accompaniment, and spoken lyrics.

An analysis of variance of magnitude estimates of loudness of three different types of complex auditory stimuli, instrumental music, instrumental music with vocal accompaniment, and spoken lyrics showed, for 100 young adults, no differences for the types of stimuli. The linguistic aspects of these complex auditory stimuli do not differentially influence loudness judgments.

A multinational comparison of aphasia management practices.

The effect of restructuring of healthcare on the quality, quantity, and nature of aphasia management is largely unknown. The current study is the first to examine access, diagnostic, treatment, and discharge patterns of patients with aphasia in Australia, Canada, the UK, the US private sector (US-Private), and the US Veterans Health Administration in the Department of Veterans Affairs (US-VA). The authors developed a 37-item survey to be completed by clinicians working with aphasic patients. The survey focused on eight areas: access to care, evaluation procedures, group treatment, number and duration of treatment sessions, limitations of the number of sessions, termination of treatment, follow-up practices, and resumption of treatment. 394 surveys were distributed and 175 were returned completed (44% return rate). Respondents represented a range of ages, work experiences, and work settings. There was considerable consistency among respondents from our five healthcare systems. Results suggest that patients may be routinely denied treatment in direct contradiction to the research literature. Just as we carefully monitor the progress of patients receiving our treatment, we are obliged to monitor the effects of managed care on our patients, fellow clinicians, and our profession.
