Learning style preferences: Vocational students and teachers

This study investigates, using the Learning Style Questionnaire, the learning style preferences of a group of vocational tertiary students and their teachers. It seeks to identify learning style differences, if any, between students in various stages of their course, between sexes and between “high” and “low” achieving students and their teachers. Furthermore, it examines the similarities and differences between the preferred learning style of the chosen sample of students and other tertiary vocational students. The major findings for the students, relevant to the above variables, and the teachers are discussed. As well, with respect to teachers and students, the implications of attempting to match teaching and learning styles are examined.     

Interobserver Agreement in the Assessment of Parental Behavior and Parent-Adolescent Conflict: African American Mothers, Daughters, and Independent Observers

Agreement between 57 African American mothers and their early adolescent daughters on measures of maternal support, maternal restrictive control, and parent-adolescent conflict were examined. To assess the relative validity of these reports, the study then evaluated them against the ratings of independent observers. Additionally, mother and daughter reports were combined to examine validity coefficients based on aggregate scores of each construct. All analyses were based on 2 sets of objective criterion ratings, ratings provided by coders of similar ethnic background (African American) and coders who were ethnically dissimilar (non-African American) to the families they rated. Overall, adolescents provided ratings that were more valid than those of their mothers when evaluated against both sets of independent ratings. Adolescent ratings of maternal control and parent-adolescent conflict converged at significantly higher levels than the ratings provided by their mothers. Maternal and adolescent reports of maternal support converged with objective criteria at statistically comparable levels. Validity coefficients for adolescent reports were also higher than those based on aggregate mother-daughter scores. Secondary analyses further revealed that African American coders rated mothers as less controlling and rated the dyadic interactions as less conflictual, and that their ratings were more consistent with the perceptions of the African American mothers and adolescents than were those provided by non-African American coders.     

Innovations in university finance: A growing necessity,and intelligent too!

In increasing numbers, public and particularly private colleges and universities are facing financing crunches associated with declining enrollments, cuts in federal aid programs, reduced grant pools, etc. These financing challenges are evident not only in terms of capital investment needs but also short-term operating demands. However, universities and colleges do have vehicles available to them to deal with both short-term and long-term needs—in the debt markets. Variable rate demand bonds and tax-exempt variable rate demand bonds are currently being marketed for just such purposes. In addition, the future appears bright for a currently unavailable instrument—real rate bonds which could further reduce the financing expenses for schools. The characteristics, advantages, and disadvantages of each are discussed along with some examples of their superiority to alternative financing.     

Credits, curriculum, and control in higher education: Cross-national perspectives

Through an examination of the higher education systems in threecountries (Indonesia, Nicaragua, and Vietnam), the authors explore howthe use of academic credits for monitoring student progress has been andcontinues to be linked to policies and institutions associated withcapitalist, market-driven economic systems. The recent histories ofthese countries and their current social and political contexts areanalyzed in relation to three interrelated themes that have emerged fromthe analysis of the three cases. These themes are: (1) Linkages topolitical and economic systems: higher education as vocationaltraining, (2) Standardization, efficiency, andtechnocracy, and (3) Who controls the curriculum? Inconclusion, the authors suggest that the academic credit system,embedded within a network of other educational practices, hastransformed the university into an institution focused on relativelynarrow, utilitarian aims rather than a more universal pursuit ofknowledge.     

Perceptions of two television cartoons: Powerpuff girls and Johnny Bravo

“Powerpuff Girls” (PPG) and “Johnny Bravo” (JB) are two recent additions to cartoon programming on the Cartoon Network. In Study 1 over three‐fourths of 187 elementary school children indicated that they had watched JB and PPG. These children perceived PPG to be significantly more aggressive than JB. In Study 2 two trained, independent raters scored JB, compared to PPG, as more likely to make appearance‐enhancing actions and more likely to use come‐ons while the PPG were more aggressive and more likely to giggle/laugh. Johnny was more likely to be the recipient of aggressive behaviors, rather than be aggressive himself.

Effectiveness of Podcasts Delivered on Mobile Devices as a Support for Student Learning During General Chemistry Laboratories

Chemistry instructors in teaching laboratories provide expert modeling of techniques and cognitive processes and provide assistance to enrolled students that may be described as scaffolding interaction. Such student support is particularly essential in laboratories taught with an inquiry-based curriculum. In a teaching laboratory with a high instructor-to-student ratio, mobile devices can provide a platform for expert modeling and scaffolding during the laboratory sessions. This research study provides data collected on the effectiveness of podcasts delivered as needed in a first-semester general chemistry laboratory setting. Podcasts with audio and visual tracks covering essential laboratory techniques and central concepts that aid in experimental design or data processing were prepared and made available for students to access on an as-needed basis on iPhones^® or iPod touches^®. Research focused in three areas: the extent of podcast usage, the numbers and types of interactions between instructors and student laboratory teams, and student performance on graded assignments. Data analysis indicates that on average the podcast treatment laboratory teams accessed a podcast 2.86 times during the laboratory period during each week that podcasts were available. Comparison of interaction data for the lecture treatment laboratory teams and podcast treatment laboratory teams reveals that scaffolding interactions with instructors were statistically significantly fewer for teams that had podcast access rather than a pre-laboratory lecture. The implication of the results is that student laboratory teams were able to gather laboratory information more effectively when it was presented in an on-demand podcast format than in a pre-laboratory lecture format. Finally, statistical analysis of data on student performance on graded assignments indicates no significant differences between outcome measures for the treatment groups when compared as cohorts. The only statistically significant difference is between students who demonstrated a high level of class participation in the concurrent general chemistry lecture course; for this sub-group the students in the podcast treatment group earned a course average that was statistically significantly higher than those in the lecture treatment group.     

Video Games as Technical Communication Ecology

With an ecological approach to the genres that circulate within communities of practice, this article traces the overlap between technical communication and online gaming communities in terms of their rhetorical uses of technical communication genres. Through shared practices, technologies, and epistemologies, online gaming environments call upon gamers to become technical communicators and provide opportunities for technical communicators to apply their expertise within the gaming industry.     

Designing information communities: Ethical issues in the information age

Abstract

The worldwide use of computers, telecommunications, and other information technologies is giving rise to the formation of new communities called “information communities.” In the United States, for example, more people are employed as information givers, takers, or orchestrators in these communities than in any other occupation class. With so many social resources going into the conduct of these communities, it is essential that they are designed to be ethical. This requires that we identify the parties involved in each community, that we be empathetic and sympathetic to their needs and that we follow Kant's dictum by always treating them as “ends in themselves.”     

How U.S. cities compete through information technology: Securing an urban advantage

Abstract

The information age is bringing about a change in the world division of labor. Many of the great trading cities that arose during the Industrial Revolution as shipping, railroad, and financial centers are now facing new challenges, challenges brought about by global telecommunications. Information technology and the changing nature of business and government offer new opportunities and threats to these and other cities as they strive to acquire or retain treasured economic activity. Telecommunications and computation capacity are among the tools cities can use as they vie with one another for this commerce.

This study describes how U. S. cities are affected by these trends and summarizes some of the key technological and policy issues involved. Several case studies are reported, which show the various strategies used by large cities such as New York and Boston, progressive Midwest cities such as Omaha, and small cities such as Heathrow, Florida. Some preliminary principles of success are adduced.
