Economics of Distance and Online Learning: Theory,Practice, and Research William J. Bramble and Santosh Panda,Editors

Business school deans at institutions accredited by the Association to Advance Collegiate Schools of Business were surveyed on distance education programs offered at their respective schools. This study examined sixteen characteristics of the distance education programs: the number of offerings, the question of not offering distance education, future plans, degree level of programs, number of years offered, number of graduates, length of programs, public or private institutions, grant funding, faculty qualifications and student-faculty ratio, method of delivery, use of a librarian, geographic areas served, tuition rates, financial aid, and the successful aspects. The results of this study may be used to make decisions in planning new distance education programs and the enhancement of existing programs.     

On the Effectiveness of Pop-Up English Language Glossary Accommodations for EL Students in Large-Scale Assessments

This study examined the effectiveness and influence on validity of a computer-based pop-up English glossary accommodation for English learners (ELs) in grades 3 and 7. In a randomized controlled trial, we administered pop-up English glossaries with audio to students taking a statewide accountability English language arts (ELA) and mathematics assessments. As is typically found, EL students exhibited lower achievement scores than non-EL students in all portions of the test. The pop-up glossaries provided inconsistent benefit for EL students. There was some evidence that the pop-up English glossaries had a minimal inhibitory effect for 3rd-grade students on both the ELA and mathematics assessment. Furthermore, 7th-grade ELs also showed slightly inhibited performance when using the pop-up glossary on the mathematics assessment. However, 7th-grade EL students had a performance benefit when using the pop-up glossary on the ELA assessment. We discuss how increased cognitive load placed on younger students may play a role in diminishing performance when using pop-up glossaries. We explore potential explanations for the difference outcomes between mathematics and ELA in grade 7.     

Predictors of placement for children who initially remained in their homes after an investigation for abuse or neglect

Objective

To examine the frequency and predictors of out-of-home placement in a 30-month follow-up for a nationally representative sample of children investigated for a report of maltreatment who remained in their homes following the index child welfare report.

Methods

Data came from the National Survey of Child and Adolescent Well-being (NSCAW), a 3-year longitudinal study of 5,501 youth 0-14 years old referred to child welfare agencies for potential maltreatment between 10/1999 and 12/2000. These analyses focused on the children who had not been placed out-of-home at the baseline interview and examined child, family and case characteristics as predictors of subsequent out-of-home placement. Weighted logistic regression models were used to determine which baseline characteristics were related to out-of-home placement in the follow-up.

Results

For the total study sample, predictors of placement in the 30-month follow-up period included elevated Conflict Tactics Scale scores, prior history of child welfare involvement, high family risk scores and caseworkers’ assessment of likelihood of re-report without receipt of services. Higher family income was protective. For children without any prior child welfare history (incident cases), younger children, low family income and a high family risk score were strongly related to subsequent placement but receipt of services and case workers’ assessments were not.

Conclusions/practice implications

Family risk variables are strongly related to out-of-home placement in a 30-month follow-up, but receipt of child welfare services is not related to further placements. Considering family risk factors and income, 25% of the children who lived in poor families, with high family risk scores, were subsequently placed out-of-home, even among children in families who received child welfare services. Given that relevant evidence-based interventions are available for these families, more widespread tests of their use should be explored to understand whether their use could make a substantial difference in the lives of vulnerable children.     

Visual constructive and visual-motor skills in deaf native signers

Visual constructive and visual-motor skills in the deaf population were investigated by comparing performance of deaf native signers (n=20) to that of hearing nonsigners (n=20) on the Beery-Buktenica Developmental Test of Visual-Motor Integration, Rey-Osterrieth Complex Figure Test, Wechsler Memory Scale Visual Reproduction subtest, and Stanford-Binet Intelligence Scale Paper Folding and Cutting subtest. Deaf signers were found to perform similarly to hearing controls, suggesting that these tests are valid assessment instruments to use with deaf individuals.     

Peer contagion of aggression and health risk behavior among adolescent males: an experimental investigation of effects on public conduct and private attitudes

Peer contagion of adolescent males' aggressive/health risk behaviors was examined using a computerized "chat room" experimental paradigm. Forty-three 11th-grade White adolescents (16-17 years old) were led to believe that they were interacting with other students (i.e., "e-confederates"), who endorsed aggressive/health risk behaviors and whose ostensible peer status was experimentally manipulated. Adolescents displayed greater public conformity, more internalization of aggressive/health risk attitudes, and a higher frequency of actual exclusionary behavior when the e-confederates were high in peer status than low. Participants' level of social anxiety moderated peer contagion. Nonsocially anxious participants conformed only to high-status peers, whereas socially anxious participants were equally influenced by low- and high-status peers. The role of status-maintenance motivations in aggression and risk behavior, and implications for preventive intervention, are discussed.

A query-based approach in Web search instruction: An assessment of current practice

An instruction program that covers search tools on the Web should incorporate a user's information need as the basis for teaching these tools. This article lays the theoretical groundwork for such a query-based approach, deriving its argument from the literature published in the early days of databases in libraries. A review of recent literature as well as tutorials on the Web reveals that librarians do not routinely consider a user's query in their training in the use of Web-based search tools. Other training elements are more prevalent, in particular the nature of search tools, search strategies and the evaluation of results found in a search. When training recommends a context for searching the Web, the advice tends to be of a general nature. These results suggest that librarians may not routinely be teaching queries as a strategy for selecting and using search tools on the Web. Suggestions for further research are presented to explore these findings.     

The effects of frequency of encouragement on performance during maximal exercise testing

The aim of this study was to determine the effects of frequency of verbal encouragement during maximal exercise testing. Twenty-eight participants (12 males, 16 females) aged 20.9 +/- 1.5 years (mean +/- s) performed a maximal exercise test (VO2max) on a treadmill without any verbal encouragement. The participants were matched according to their pre-test VO2max and placed into either a control group or one of three experimental groups. They performed a second exercise test (post-test) 1 week later. During the second test, the control group received no verbal encouragement; the 20 s (20E), 60 s (60E) and 180 s (180E) encouragement groups received verbal encouragement every 20, 60 and 180 s, respectively, beginning with stage 3 of the exercise test. Relative VO2max, exercise time, blood lactate concentration, respiratory exchange ratio (RER) and ratings of perceived exertion (RPE) were not significantly different from the first test to the second test for the control group without verbal encouragement and the 180E group that received infrequent encouragement. Post-test values were significantly higher than pre-test values for the 20E and 60E groups. The post-test values of the 20E group were significantly higher than their pre-test values for relative VO2max (P < 0.001), exercise time (P < 0.0001), blood lactate concentration (P < 0.05), RER (P < 0.01) and RPE (P < 0.0001); this was also the case for the 60E group for relative VO2max (P < 0.01), blood lactate concentration (P < 0.05), RER (P < 0.05) and RPE (P < 0.05). The results suggest that frequent verbal encouragement (every 20 s and 60 s in the present study) leads to significantly greater maximum effort in a treadmill test than when no encouragement is given or when the encouragement is infrequent (i.e. every 180 s).
