Learner Characteristics that Influence the Treatment Effectiveness of Early Literacy Interventions: A Meta‐Analytic Review     

J. Ron Nelson  Gregory J. Benner  Jorge Gonzalez 《Learning disabilities research & practice》2003,18(4):255-267

The purpose of this article was to systematically review the available research on learner characteristics that influence the treatment effectiveness of early literacy interventions. Meta‐analytic procedures were applied to a total of 30 studies that met the inclusionary and exclusionary criteria. Mean average effect sizes were computed for seven primary learner characteristic categories: (1) rapid naming, (2) alphabetic principle, (3) phonological awareness, (4) problem behavior, (5) memory, (6) IQ, and (7) demographic. The primary learner characteristics that influenced the treatment responsiveness of early literacy interventions were, in order of magnitude, rapid naming, problem behavior, phonological awareness, alphabetic principle, memory, IQ, and demographics. With the exception of the demographic category, the obtained effect sizes for the primary learner characteristics were moderately large. The demographic primary learner characteristic (i.e., disability, ethnicity, grade‐level status) of children was not statistically (p < 0.05) distinct from zero. The findings, limitations, and future research needs are discussed.  相似文献   

Optimal sampling frequency in recording of resistance training exercises     

Paolo Bardella  Irene Carrasquilla García  Marco Pozzo  Julio Tous-Fajardo  Eduardo Saez de Villareal 《Sports biomechanics / International Society of Biomechanics in Sports》2017,16(1):102-114

The purpose of this study was to analyse the raw lifting speed collected during four different resistance training exercises to assess the optimal sampling frequency. Eight physically active participants performed sets of Squat Jumps, Countermovement Jumps, Squats and Bench Presses at a maximal lifting speed. A linear encoder was used to measure the instantaneous speed at a 200 Hz sampling rate. Subsequently, the power spectrum of the signal was computed by evaluating its Discrete Fourier Transform. The sampling frequency needed to reconstruct the signals with an error of less than 0.1% was f_99.9 = 11.615 ± 2.680 Hz for the exercise exhibiting the largest bandwidth, with the absolute highest individual value being 17.467 Hz. There was no difference between sets in any of the exercises. Using the closest integer sampling frequency value (25 Hz) yielded a reconstruction of the signal up to 99.975 ± 0.025% of its total in the worst case. In conclusion, a sampling rate of 25 Hz or above is more than adequate to record raw speed data and compute power during resistance training exercises, even under the most extreme circumstances during explosive exercises. Higher sampling frequencies provide no increase in the recording precision and may instead have adverse effects on the overall data quality.  相似文献   

Formations of Mexicana ness: Trenzas de identidades multiples Growing up Mexicana : Braids of multiple identities     

Francisca E. Gonzalez 《International journal of qualitative studies in education》2013,26(1):81-102

As California's complexion and social panorama changes in color and class so must the directions for writing ethnicity and social analysis. This qualitative study seeks to break out of paradigmatic insulation by proposing innovative perspectives and directions for creating subversive narratives about our own realities. It also seeks to inform current social analysis about Mexicana quality of life and about educationalpolicy on Mexicana educacion (education of the whole person) and school cultures. This article examines how Mexicana identities are created, shaped, and developed through the construction of narratives. I interpret these with the analytical tools of trenzas that ''braids'' critical race theory and multidimensional feminist frames, platicas (popular conversations) and cultural intuition, and the engagement of myself, the researcher, and the young Mexicanas participating in the study. By claiming our space and voicing our feelings and meanings about language, Aztlan culture and identity, and womanhood, we correct stereotypic representations that render Mexicanas vulnerable and dismissed from U.S. civic life and public education. In light of the missing discourse about young Mexicana identity formations, this research makes possible trenzas ''braids'' of multiple identities and tools for transforming educational research, curriculum, and the building of education partnerships.  相似文献   

Perceived health problems in swimmers according to the chemical treatment of water in swimming pools     

Álvaro Fernández-Luna  Pablo Burillo  José Luis Felipe  Julio del Corral  Jorge García-Unanue  Leonor Gallardo 《European Journal of Sport Science》2016,16(2):256-265

The objective of this study was to determine which chemical treatment used for disinfecting water in indoor swimming pools had the least impact on users' perceptions of health problems, and which generated the greatest satisfaction with the quality of the water. A survey on satisfaction and perceived health problems was given to 1001 users at 20 indoor swimming pools which used different water treatment methods [chlorine, bromine, ozone, ultraviolet lamps (UV) and salt electrolysis]. The findings suggest that there is a greater probability of perceived health problems, such as eye and skin irritation, respiratory problems and skin dryness, in swimming pools treated with chlorine than in swimming pools using other chemical treatment methods. Pools treated with bromine have similar, although slightly better, results. Other factors, such as age, gender, time of day of use (morning and afternoon) and type of user (competitive and recreational), can also affect the probability of suffering health problems. For all of the above, using combined treatment methods as ozone and UV, or salt electrolysis produces a lower probability of perceived health problems and greater satisfaction.  相似文献   

Mitigating the Effects of Poverty and Crime: the Long-Term Effects of an Early Intervention Programme for Children who were Developmentally Delayed and Prenatally Exposed to Cocaine     

Mary Anne Ullery  Antonio Gonzalez  Lynne Katz 《International Journal of Disability, Development & Education》2016,63(4):403-418

This study explores the long-term impact on participation in the Linda Ray Intervention Program (LRIP) for children (n = 54) who were developmentally delayed and prenatally exposed to cocaine. By identifying a group of programme graduates from a high crime/high poverty neighbourhood in Miami-Dade County using ArcGIS 10.2 software, a quasi-experimental design was used to compare children living in this area who participated in the centre-based modality (5 h a day; 5 days a week) to children living in this area who participated in the home-based modality (3 h per week) on their Florida Comprehensive Assessment Test (FCAT) reading and math scale scores in public school. The children who participated in the centre-based modality reported stronger outcomes in both math and reading FCAT scale scores at the p < .05 level and also out-performed their school-age peers on both math and reading FCAT scores at the p < .05 level.  相似文献

Eighteen new counselor educators shared in‐depth reports of their efforts to establish an early record of scholarly productivity, critical to their success in academe. Analyses of their experiences using consensual qualitative research methods revealed components of both highly positive and highly discouraging program environments and their impact on participants’ research goals.  相似文献   

Light-load maximal lifting velocity full squat training program improves important physical and skill characteristics in futsal players     

Julio Torres-Torrelo  Juan José González-Badillo 《Journal of sports sciences》2017,35(10):967-975

This study aimed to compare the effect of 6 weeks of resistance training or combined resistance training and change of direction exercises on physical performance and motor skills in futsal players. Thirty-four futsal players were divided into full squat group (SG, n = 12), combined full squat and change of direction exercises group (S+CDG, n = 12) and control group (CG, n = 10). The resistance training for SG consisted of full squat with low load (~45–58% 1RM) and low volume (4–6 repetitions), whereas the S+CDG performed the same resistance training program combined with loaded change of direction. Sprint time in 10 and 20 m, change of direction test, countermovement vertical jump (CMJ) height, maximal strength and force–velocity relationship in full squat exercise, kicking speed ball (BS_mean) and repeated sprint ability (RSA_mean) were selected as testing variables. Both experimental groups showed significant improvements for CMJ, BS_mean and all strength parameters. Only SG resulted in significant sprint gains, whereas S+CDG also achieved significant improvements in RSA_mean. The CG remained unchanged after training period. No significant differences were found between both experimental groups. These findings suggest that only 12 sessions of either lightweight resistance training alone, lifting the load at maximal intended velocity or combined with change of direction exercises is enough to improve several physical and skills capacities critical to futsal performance in adult players.  相似文献
