A meta‐analysis of Tier 2 interventions implemented within School‐Wide Positive Behavioral Interventions and Supports

This meta‐analysis synthesized 26 published single‐case design (SCD) studies on Tier 2 behavior interventions implemented within the educational framework of school‐wide positive behavioral interventions and supports. We used Tau‐U indices to determine the overall magnitudes of effect of the Tier 2 behavior interventions and the potential variables that moderate improved student behavioral outcomes. The 26 studies that were analyzed included a total of 243 student participants. The studies were evaluated to determine whether and to what extent they met What Works Clearinghouse (WWC) SCD standards. Of these, 10 studies were confirmed as meeting WWC SCD standards with or without reservations. Notable findings were that outcomes for students in kindergarten and secondary grade levels were limited, and insufficient screening methods were used to identify and select students needing Tier 2 interventions. The results indicate that the literature reports Tier 2 interventions with effect sizes ranging from 0.26 to 0.98. Average effect size for social skills instruction was found to be large, whereas Check‐in/Check‐out, group contingency, and intervention packages had medium effect sizes. Moderator analyses indicated different effect sizes across intervention types, outcomes, and implementers. The results are discussed in relation to implications for practice, limitations, and future research.     

Public sea turtle watches serve as effective environmental education

To understand both immediate and longer-term effects of a short duration, interpretive wildlife tourism program, we studied responses from participants in a sea turtle watch program. This program comprised an interpretive presentation followed by an opportunity to view a nesting loggerhead sea turtle (Caretta caretta). We conducted 37 programs in 2013 and 2014, for 843 participants, of whom 70.5% were able to see a nesting turtle. We measured participant attitudes, knowledge, intention to act, and long-term behavior change. Initial participant responses indicated prior interest in nature and environmental topics, and a knowledge base focused on biological sea turtle information. After the interpretive presentation, participants chose to provide conservation-related information as opposed to natural history-related information. Intention to engage in conservation behaviors was high following the turtle watch experience, regardless of whether a turtle was seen. The conservation value of our turtle watch program is expressed through conservation-focused knowledge acquisition by participants and their high post-program intention to engage in behaviors benefiting sea turtles, both of which precede long-term behavior change in an interdisciplinary model of behavior change.     

The role of comparison in perceptual learning: effects of concurrent exposure to similar stimuli on the perceptual effectiveness of their unique features

In three experiments, rats were given concurrent exposure to a compound flavor (AX) and to one of the elements of the compound (X). The perceptual effectiveness of A was then assessed by a test involving generalization of a conditioned aversion. Comparison was made with a preexposure procedure in which the compound and the common element were presented on separate trials, either in alternation or in separate blocks of trials. The effectiveness of the unique cue was less after blocked preexposure than after either of the other procedures; concurrent preexposure did not produce a greater effect than did alternating preexposure. These results challenge the suggestion that concurrent preexposure engages a special comparison process that will facilitate this form of perceptual learning.     

Conservation of a contemporary lacquered screen: A collaborative,interdisciplinary, international project involving the artist,fabricators, and conservators from three different areas

This paper discusses issues surrounding the conservation of contemporary art within the private sector using a real example, a freestanding hinged and lacquered screen. The artwork developed severe damage whilst on display in a private collection when a section of the lacquer cracked and delaminated from the bottom of one of the panels, taking paint with it. This significantly compromised its pristine appearance, and preliminary observations suggested that restoration using traditional consolidation, retouching and varnishing techniques was highly unlikely to be successful. Initial contact with the artist led to negotiation with the original fabricator's studio. This highlighted the challenges involved in reinstating the badly damaged paint and resin using an approach that would still be acceptable within the code of ethics of the conservation profession, and the potential problems of sharing information with experts who are not conservators. Part painting, part sculpture and part furniture, the screen does not fall into the standard divisions of conservation practice. Its eventual treatment demanded collaboration between specialists in paintings, sculpture, lacquer work, and conservation science. The paper addresses three areas of importance to the conservation of contemporary art: the challenges of working as an interdisciplinary team to deal with complex (and sometimes conflicting) ethical approaches and material requirements; the difficulty in balancing the desire to preserve original materials with the need to produce a pristine result, and the importance of the artist's ratification of conservation to the market value of the work.     

International online collaboration as a boundary crossing activity for vocational educators

Vocational educators cross boundaries between practices in schools, colleges and workplaces, renegotiating their identities as professionals in a particular vocation and as educators. In order to support learners to enter the global workforce, they also require opportunities to cross boundaries through international practices. However, opportunities for international and intercultural learning are often limited, particularly for trainee vocational educators. This paper highlights an online collaborative process (COLIGE) designed to develop competencies for global education. The COLIGE process has been evaluated through the lens of boundary crossing. Participants were trainee vocational educators undergoing their professional teaching qualification in Scotland and Finland. Action research was undertaken during this three-year project to explore participants’ experiences and evaluate the learning mechanisms observed during the activities. Findings suggest activity though all four learning mechanisms (identification, coordination, reflection, transformation), although they were not universally experienced. Difficulties faced by learners are discussed and point to the potential for transformation of practice without sequential engagement with all learning mechanisms.

Presidential Spotlight: Reflection and Advocacy—Creating and Addressing Elements Central to Leadership and Higher Education

Drawing from my experiences as President of the Central States Communication Association, I examine how service allows for opportunities to create relationships, identity, and leadership in profound ways. I then consider how Communication scholars can unite to resolve ongoing economic issues that threaten both communication pedagogy and research. The academy as a whole faces serious economic challenges; this essay identifies some of these specific problems and potential action steps that academic associations can take in an advocacy role on this front. This is done in the hope that associations or even individuals begin (or continue) thinking about what they can do to help address the economic issues in higher education that so many face across the academy.     

Confusion and complex learning during interactions with computer learning environments

Folk wisdom holds that being confused is detrimental to learning. However, research on emotions and learning suggest a somewhat more complex relationship between confusion and learning outcomes. In fact, it has been proposed that impasses that trigger states of cognitive disequilibrium and confusion can create opportunities for deep learning of conceptually difficult content. This paper discusses four computer learning environments that either naturally or artificially induce confusion in learners in order to create learning opportunities. First, an Intelligent Tutoring System called AutoTutor that engenders confusion through challenging problems and vague hints is described. The remaining three environments were specifically designed to induce confusion through a number of different interventions. These interventions include device breakdowns, contradictory information, and false feedback. The success and limitations of confusion induction and the impact of confusion resolution on learning are discussed. Potential methods to help learners productively manage their confusion instead of being hopelessly confused are also discussed.     

Construct Validity Evidence for Single-Response Items to Estimate Physical Activity Levels in Large Sample Studies

Valid measurement of physical activity is important for studying the risks for morbidity and mortality. The purpose of this study was to examine evidence of construct validity of two similar single-response items assessing physical activity via self-report. Both items are based on the stages of change model. The sample was 687 participants (men = 504, women = 183) who completed an 8-response (PA8) or 5-response (PA5) single-response item about current level of physical activity. Responses were categorized as meeting or not meeting guidelines for sufficient physical activity to achieve a health benefit. Maximal cardiorespiratory fitness (CRF) and health markers were obtained during a clinical examination. Partial correlation, multivariate analysis of covariance, and logistic regression were used to identify the relations between self-reported physical activity, CRF, and health markers when controlling for gender and age. Single-response items were compared to a detailed measure of physical activity. Single-response items correlated significantly with CRF determined with a maximal exercise test on a treadmill (PA8 = .53; PA5 = .57). Differences in percentage of body fat and cholesterol were in the desired direction, with those self-reporting sufficient physical activity for a health benefit having the lower values. The single-response items demonstrated evidence of construct validity and may provide feasible, cost-effective, and efficient methods to assess physical activity in large-scale studies.     

The Impact of Previous Athleticism on Exercise Habits,Physical Fitness,and Coronary Heart Disease Risk Factors in Middle-Aged Men

Abstract

A longitudinal study was performed to determine differences in physiologic variables, health behaviors, risk factors, or clinical status between former athletes (FA) (N = 345) and nonathletes (NA) (N = 75). The subjects, 420 self-referred white males aged 25-60 years old, were examined for prior athleticism and health. Athleticism was determined through self-reported high school or college athletic history. Baseline physiologic and health behavior characteristics were not different between the two groups. Of those study participants (N = 203 FA, 48 NA) who were sedentary at baseline, 208 (N = 167 FA, 41 NA) voluntarily began an exercise program during the followup period (average followup = 56 months). These numbers correspond to exercise adoption rates of 82 and 85 % for FA and NA respectively, and were not statistically different (95% CI FA = 0.76, 0.88, NA = 0.73, 0.97). Repeated measures analysis of covariance was performed to determine if physiologic responses to adoption were different between FA and NA. No statistically significant difference was found between the two groups, time effects were similar in the two, and no significant interaction of time by group was observed. We conclude that prior athleticism has little apparent impact on health and health behaviors, thus suggesting that contemporaneous exercise has more impact on clinical variables.
