THE EFFECTS OF TARGETED ENGLISH LANGUAGE ARTS INSTRUCTION USING MULTIMEDIA APPLICATIONS ON GRADE THREE STUDENTS’ READING COMPREHENSION, ATTITUDE TOWARD COMPUTERS, AND ATTITUDE TOWARD SCHOOL

The purpose of this study was to investigate the specific effects of targeted English Language Arts (ELA) instruction using multimedia applications. Student reading comprehension, student attitude toward computers, and student attitude toward school were measured in this study. The study also examined the perceptions, of selected students, of the use of these applications. In this study, targeted ELA instruction was compared to similar instruction of ELA skills with the addition of multimedia software applications. In this study a sampling of grade 3 students in a medium-sized suburban school district received 10 weeks of targeted ELA instruction using traditional teaching methods. From this sample, approximately half of the students received instruction with ELA multimedia applications in lieu of a portion of the allotted ELA instruction time Two instruments were administered to all students as a pretest and as a posttest; the New York State English Language Arts Exam Part 1 (NYS ELA) and the Young Children’s Computer Inventory (YCCI). In addition, five students were selected for a semi-structured interview. The interviews explored the perceptions of the students who used the ELA multimedia applications in school and showed the greatest gain in reading comprehension scores at the conclusion of the treatment period. A pretest ANOVA was used to verify equivalency of groups for reach variable. Following this, a MANOVA revealed that students who participated in the treatment group and received ELA instruction using online multimedia applications scored significantly higher than students in the control group. Univariate ANOVA revealed that students in the treatment group scored higher on the attitude toward computers measure and the reading comprehension measure, and that there was no significant difference in scores on the attitude toward school measure between treatment and control groups. Analysis of the qualitative data revealed three themes that recurred throughout the five interviews. The themes were: having fun, learning content, and expressing emotions. Qualitative and quantitative data were triangulated, and implications for practitioners and researchers were discussed

Enjoyed or bored?:A study into achievement emotions and the association with barriers to learning in MOOCs

MOOCs are accessible online personal development opportunities in which learners can expand their knowledge on many topics. Yet, the experience of barriers to learning often hinders learners from achieving their personal learning goals. Therefore, it is important to have insight into determinants that may influence the experience of (certain) barriers. This study investigated whether the emotional determinants enjoyment and boredom, which are known to impact learner achievement and motivation, affect the experience of (specific) barriers while learning in MOOCs. The results show that boredom did affect the experience of barriers related to technical and online related skills, social context and time, support and motivation, yet it did not affect the experience of barriers related to the design of the MOOC. Enjoyment was not correlated to any of the barriers. Furthermore, the same analysis comparing men to women again revealed that boredom did not significantly affect the experience of barriers related to the design of the MOOC, yet did significantly affect the experience of the other barriers. No, significant differences were found between males and females. These findings may serve as input for supporting learners in achieving their individual learning goals

Prevalence of Pituitary Hormone Dysfunction, Metabolic Syndrome, and Impaired Quality of Life in Retired Professional Football Players: A Prospective Study

Hypopituitarism is common after moderate and severe traumatic brain injury (TBI). Herein, we address the association between mild TBI (mTBI) and pituitary and metabolic function in retired football players. Retirees 30–65 years of age, with one or more years of National Football League (NFL) play and poor quality of life (QoL) based on Short Form 36 (SF-36) Mental Component Score (MCS) were prospectively enrolled. Pituitary hormonal and metabolic syndrome (MetS) testing was performed. Using a glucagon stimulation test, growth hormone deficiency (GHD) was defined with a standard cut point of 3 ng/mL and with a more stringent body mass index (BMI)-adjusted cut point. Subjects with and without hormonal deficiency (HD) were compared in terms of QoL, International Index of Erectile Function (IIEF) scores, metabolic parameters, and football career data. Of 74 subjects, 6 were excluded because of significant non-football-related TBIs. Of the remaining 68 subjects (mean age, 47.3±10.2 years; median NFL years, 5; median NFL concussions, 3; mean BMI, 33.8±6.0), 28 (41.2%) were GHD using a peak GH cutoff of <3 ng/mL. However, with a BMI-adjusted definition of GHD, 13 of 68 (19.1%) were GHD. Using this BMI-adjusted definition, overall HD was found in 16 (23.5%) subjects: 10 (14.7%) with isolated GHD; 3 (4.4%) with isolated hypogonadism; and 3 (4.4%) with both GHD and hypogonadism. Subjects with HD had lower mean scores on the IIEF survey (p=0.016) and trended toward lower scores on the SF-36 MCS (p=0.113). MetS was present in 50% of subjects, including 5 of 6 (83%) with hypogonadism, and 29 of 62 (46.8%) without hypogonadism (p=0.087). Age, BMI, median years in NFL, games played, number of concussions, and acknowledged use of performance-enhancing steroids were similar between HD and non-HD groups. In summary, in this cohort of retired NFL players with poor QoL, 23.5% had HD, including 19% with GHD (using a BMI-adjusted definition), 9% with hypogonadism, and 50% had MetS. Although the cause of HD is unclear, these results suggest that GHD and hypogonadism may contribute to poor QoL, erectile dysfunction, and MetS in this population. Further study of pituitary function is warranted in athletes sustaining repetitive mTBI

Biomarkers and Noncalcified Coronary Artery Plaque Progression in Older Men Treated With Testosterone.

ObjectiveRecent results from the Cardiovascular Trial of the Testosterone Trials showed that testosterone treatment of older men with low testosterone was associated with greater progression of noncalcified plaque (NCP). We evaluated the effect of anthropometric measures and cardiovascular biomarkers on plaque progression in individuals in the Testosterone Trial.MethodsThe Cardiovascular part of the trial included 170 men aged 65 years or older with low testosterone. Participants received testosterone gel or placebo gel for 12 months. The primary outcome was change in NCP volume from baseline to 12 months, as determined by coronary computed tomography angiography (CCTA). We assayed several markers of cardiovascular risk and analyzed each marker individually in a model as predictive variables and change in NCP as the dependent variable.ResultsOf 170 enrollees, 138 (73 testosterone, 65 placebo) completed the study and were available for the primary analysis. Of 10 markers evaluated, none showed a significant association with the change in NCP volume, but a significant interaction between treatment assignment and waist-hip ratio (WHR) (P = 0.0014) indicated that this variable impacted the testosterone effect on NCP volume. The statistical model indicated that for every 0.1 change in the WHR, the testosterone-induced 12-month change in NCP volume increased by 26.96 mm3 (95% confidence interval, 7.72-46.20).ConclusionAmong older men with low testosterone treated for 1 year, greater WHR was associated with greater NCP progression, as measured by CCTA. Other biomarkers and anthropometric measures did not show statistically significant association with plaque progression
