Effectiveness of a Computer-Based Program for Improving the Reading Performance of Deaf Students

The purpose of this study was to determine if the use of the reading component of Ticket to Read®, a computer-based educational program, developed to improve hearing students’ fluency could improve deaf students’ fluency in order to improve comprehension. Fluency, the ability to read text accurately and automatically, forms a bridge from decoding to comprehension. This research is significant because the median reading level of deaf students who graduate high school has remained around a fourth grade level equivalent for the past thirty years, and there is a paucity of research that examines evidence-based practices to improve the reading performance of deaf students. There were 27 subjects in this study from an urban day school for the deaf. A dependent t-test was conducted using the subjects’ scores on a pretreatment and posttreatment reading assessment after nine weeks of treatment. No significant difference from pretreatment to posttreatment assessment was found, t(26) = 1.813, p \u3e .05. In addition, an exploratory analysis using treatment and control groups was conducted using a quasi-experimental design based on mean gain scores from a pretreatment and posttreatment reading assessment. Twenty-seven pairs of subjects were matched on ethnicity, gender, and grade level to determine the main effect of treatment, the interaction effect of treatment and gender, and the interaction effect of treatment and grade level. No significant difference was found for the main effect of treatment, F(1,42) = 1.989, p \u3e.05. Statistical significance was not found for the interaction between treatment and gender, F(1,50) = 1.209, p \u3e.05. Statistical significance was not found for the interaction between treatment and grade level, F(2,48) = .208, p \u3e.05. The results of this study have implications in the field of deaf education and are congruent with the findings of similar studies involving Repeated Readings to influence comprehension. Although significant tests were non-significant regarding students’ improvement on the reading assessment after the intervention, the direction and magnitude of the mean differences effect sizes for students in the treatment group support the need for further research regarding the evaluation of computer-based educational programs that can be used as effective educational strategies to improve deaf students’ reading performance

The Plant Management Network: A New Online Source of Applied Plant Science Information

The Plant Management Network (PMN) is a new online, multi-disciplinary, plant science network of peer-reviewed journals and applied plant information serving as an important resource for Extension professionals and their audiences. PMN is designed to extend Extension research and information out to growers, advisors, and the Extension community. In addition to the journals, partner publications, and image gallery--presently searchable on the site--new features are being prototyped, including scripted PowerPoint presentations, online posters, and continuing education modules. Articles are published on PMN within 1-3 weeks of acceptance, without charge. Individuals and partner organizations support the PMN through annual subscriptions

Legume Re-Establishment in Pastures after the Application of Residual Herbicides

Integrated management of pastures and hayfields sometimes require the application of broadleaf herbicides to manage weeds. Weed infestations are usually caused by a variety of factors including but not limited to drought, poor grazing management, and feeding weed infested hay in pastures. Weeds can adversely affect livestock access to forage as well as reduce forage quantity and quality. Producers are often hesitant to apply herbicides to manage weeds because of the effect the herbicides will have on forage legumes present in the pasture

Using Modeling and Simulation to Examine the Benefits of a Network Tasking Order

The Global Information Grid (GIG) is the military’s computer and communications network which supports the myriad of military missions. Military missions are highly planned, passing through many hands in the strategy-to-task methodology to ensure completeness, accuracy, coordination, cohesion, and appropriateness. A benefit of this planning is the possibility to collect knowledge of future conditions that could be of use to network designers whose goals include optimizing and protecting the GIG. This advanced knowledge includes which networked military equipment will be involved, what their capabilities are, where they will be, when they will be there, and particulars on the required data flows. A Network Tasking Order process is proposed as a means of collecting this information, analyzing the information to generate network taskings, and disseminating those taskings. Tactical integration of assets in mobile networks is introduced as another planning variable in the battlefield; not unlike logistical considerations such as fuel, ammunition, water, and so on used currently in operation planning. Modeling and simulation is used to support the proposed benefits

Development of Methodologies to Reduce the DCAD of Hay Forages for Transition Dairy Cows

Ration formulation for dairy cows just prior to parturition must control the dietary cation-anion difference (DCAD) if hypocalcemia and milk fever are to be avoided. One key to reducing hypocalcemia is to avoid incorporation of high-K forages into the ration. The excessive K content of these forages can cause metabolic alkalosis in the cow and subsequently hypocalcemia and milk fever. Alfalfa and other cool-season grasses are often used in dairy rations. Reducing K content of forages can be achieved by restricting K fertilization so that soils do not support luxury consumption. Since K is the major cation contributing to highDCAD diets, an obvious solution is to limit K fertilization of the forage crop to avoid luxury consumption of K. However, some forages may have reduced yield and increased winter kill if K concentrations are less than 2.0%, particularly alfalfa. Thus, producing alfalfa with less than 2% K may not be profitable, especially in northern regions. In addition to decreasing forage K, the producer can also increase the Cl content of the forages, and the resulting DCAD will be more favorable for the late-gestation cows

Effects of Chemical Composition on Forage Intake of Heifers Fed Hays of Different Species

Alfalfa, smooth bromegrass, and big bluestem hays harvested at two maturities differing by four weeks were fed at mature-to-immature hay ratios of 1:0, 2:1, 1:2, and 0:1 to yearling heifers in an experiment with a three 4 x 4 Latin square design with 14 day periods. Concentrations of in vitro digestible dry matter and crude protein were greater and concentrations of neutral detergent fiber, acid detergent fiber, and indigestible neutral detergent fiber (determined by either a manual method with a 96 hour incubation or an automated method with a 48 hour incubation) were less in alfalfa hay than in the two grass hays and in smooth bromegrass hay than in big bluestem hay. Concentrations of in vitro digestible dry matter and crude protein decreased whereas those of neutral detergent fiber, acid detergent fiber and indigestible neutral detergent fiber increased with increasing forage maturity. Consumptions of dry matter, digestible dry matter, in vitro digestible dry matter, and crude protein were greater for heifers fed alfalfa hay diets than those fed the two grasses. Consumptions of total neutral detergent fiber and indigestible neutral detergent fiber, determined by the automated method with a 48 hour incubation, were greater by heifers fed diets containing big bluestem than those fed alfalfa or smooth bromegrass diets. Consumptions of acid detergent fiber and indigestible neutral detergent fiber, determined by a manual method with a 96 hour incubation, were greater for heifers fed alfalfa or big bluestem hay diets than those of heifers fed smooth bromegrass diets. Consumption of dry matter, in vivo or in vitro digestible dry matter, crude protein, neutral detergent fiber, acid detergent fiber and automated indigestible neutral detergent fiber decreased as the mature-to-immature hay ratio decreased. Diet digestibility was not affected by forage species, but increased as the mature-toimmature hay ratio decreased. Fecal excretion of dry matter and neutral detergent fiber did not differ between forage species or mature-to-immature hay ratios. Forage dry matter intake expressed as a percentage of body weight was significantly related to the concentrations of in vitro digestible dry matter (r2=.14), crude protein (r2=.17), neutral detergent fiber (r2=.20), and manual indigestible neutral detergent fiber (r2=.18) of the hays and the concentration of digestible dry matter of the diets (r2=.43)
