Many states have scaled up School‐Wide Positive Behavioral Interventions and Supports (SW‐PBIS) with the goal of improving student behavior and academic outcomes. Although the effects of SW‐PBIS on behavioral and discipline outcomes have been promising, the findings for academic achievement have been inconclusive and are often limited to cross‐sectional data. This paper examined the longitudinal effect of SW‐PBIS on student behavioral problems and academic achievement growth in elementary and middle schools using propensity score matching. We found no statistically significant longitudinal effects of SW‐PBIS on either student behavior problems or academic achievement among elementary and middle schools in this quasi‐experimental design, even though the positive direction of longitudinal changes would be identified. The result raised questions about the efficacy of SW‐PBIS using a statewide achievement test when scaled up to a state level. Additional research is needed to better understand the impact of SW‐PBIS using rigorous scale‐up designs. 相似文献

As access to the WWW increases in schools and classrooms it is vital for educators at all levels to examine closely its potential roles in learning. Much emphasis has been placed upon making the WWW available without enough emphasis on methods of using it so students will benefit from instruction based upon it. A continuing goal of modern pedagogy is to help students move beyond the lower order cognitive domain, knowledge and comprehension, to higher order thinking skills: application; analysis;, synthesis; and evaluation. Students also need critical thinking skills. These skills are necessary for dealing with the demands of the future information society, which will be even more complex and demanding than at present. In order to foster the skills mentioned above, teachers are urged to provide learning environments that are learner-centred, authentic, problem-based and collaborative. Les relations entre le World Wide Web et les aptitudes des pensées. Comme l'accès au WWW s'accroît dans les écoles et les classes il est vital que les enseignants À tous niveaux examinent de près son rÔle potentiel en éducation. On a mis beaucoup l'accent sur les possibilités d'accès au WWW sans mettre assez l'accent sur les méthodes d'emploi par les étudiants de facon À ce qu'ils puissent bénéficier de l'instruction qu'il permet. Un objectif constant de la pédagogie moderne est d'aider les étudiants À dépasser le domaine cognitif limité. le savoir et la compréhension vers des aptitudes de pensée d'un ordre supérieur : applications, analyses, synthèses et évaluations. Les étudiants ont aussi besoin de pensée critique - ces aptitudes sont nécessaires pour faire face aux demandes de la future société de l'information, qui sera encore plus complexe et exigeante que maintenant. De facon À favoriser les aptitudes mentionnées ci-dessus , il faut que les enseignants fournissent les environnements éducatifs qui sont centrés sur l'apprenant, authentiques, basés sur la résolution de problèmes et la collaboration. Der Zusammenhang zwischen dem World Wide Web und den Denkfähigkeiten. Mit den wachsenden Zugängen an das WWW in Schulen und Klassenräumen wird es für Lehrer auf allen Ebenen immer dringender ihre zukünftige Rolle im Unterricht zu überdenken. Es wurde sehr viel Wert auf die Verfügbarkeit des WWWs gelegt, ohne jedoch auf Anwendungsmöglichkeiten zu achten damit die Lernenden von einem auf dem Web basierenden Unterricht profitieren. Ständiges Ziel moderner Pädagogik ist, Studenten zu helfen, über die untere Stufe des kognitiven Bereichs, Wissen und Verständnis, auf eine höhere Stufe des Denkprozesses zu gelangen: nämlich Anwendung, Analyse, Synthese und Bewertung. Schüler brauchen auch kritisches Denken. Diese Fähigkeiten sind notwendig im Umgang mit den Anforderungen der zukünftigen Informationsgesellschaft, die noch komplexer und schwieriger als die jetzige sein wird. Um diese Fähigkeiten zu fördern müssen Lehrer Lernumfelder schaffen, die sich am Studenten orientieren, authentisch sind, auf Problemlösungen basieren und collaborativ sind. 相似文献

Inter-day training reliability and variability in artistic gymnastics vaulting was determined using a customised infra-red timing gate and contact mat timing system. Thirteen Australian high performance gymnasts (eight males and five females) aged 11–23 years were assessed during two consecutive days of normal training. Each gymnast completed a number of vault repetitions per daily session. Inter-day variability of vault run-up velocities (at ‐18 to ‐12 m, ‐12 to ‐6 m, ‐6 to ‐2 m, and ‐2 to 0 m from the nearest edge of the beat board), and board contact, pre-flight, and table contact times were determined using mixed modelling statistics to account for random (within-subject variability) and fixed effects (gender, number of subjects, number of trials). The difference in the mean (Mdiff) and Cohen's effect sizes for reliability assessment and intra-class correlation coefficients, and the coefficient of variation percentage (CV%) were calculated for variability assessment. Approach velocity (‐18 to ‐2 m, CV = 2.4–7.8%) and board contact time (CV = 3.5%) were less variable measures when accounting for day-to-day performance differences, than pre-flight time (CV = 17.7%) and table contact time (CV = 20.5%). While pre-flight and table contact times are relevant training measures, approach velocity and board contact time are more reliable when quantifying vaulting performance. 相似文献

In the current study, we quantified biological movement variability on the start and early acceleration phase of sprinting. Ten male athletes aged 17–23 years (100-m personal best: 10.87 ± 0.36 s) performed four 10-m sprints. Two 250-Hz cameras recorded the sagittal plane action to obtain the two-dimensional kinematics of the block start and initial strides from subsequent manually digitized APAS motion analysis. Infra-red timing lights (80 Hz) were used to measure the 10-m sprinting times. The coefficient of variation (CV%) calculation was adjusted to separate biological movement variability (BCV%) from estimates of variability induced by technological error (SEM%) for each individual sprinter and measure. Pearson's product–moment correlation and linear regression analysis were used to establish relationships between measures of BCV% and 10-m sprint start performance (best 10-m time) or 10-m sprint start performance consistency (10-m time BCV%) using SPSS version 12.0. Measurement error markedly inflated traditional measures of movement variability (CV%) by up to 72%. Variability in task outcome measures was considerably lower than that observed in joint rotation velocities. Consistent generation of high horizontal velocity out of the blocks led to more stable and faster starting strides. 相似文献

Abstract The purpose of this study was to develop a regression equation to predict maximal oxygen uptake (VO2max) based on nonexercise (N-EX) data. All participants (N= 100), ages 18–65 years, successfully completed a maximal graded exercise test (GXT) to assess VO2max (M= 39.96 mL·kg -1· min -1 , SD = 9.54). The N-EX data collected just before the maximal GXT included the participant's age; gender; body mass index (BMI); perceived functional ability (PFA) to walk, jog, or run given distances; and current physical activity (PA-R) level. Multiple linear regression generated the following N-EX prediction equation (R = .93, SEE = 3.45 mL·kg -1· min -1 , %SEE= 8.62): VO2max (mL·kg -1· min -1 ) = 48.0730 + (6.1779 x gender; women = 0, men = 1) – (0.2463 x age) – (0.6186 x BMI) + (0.7115 x PFA) + (0.6709 x PA-R). Cross validation using PRESS (predicted residual sum of squares) statistics revealed minimal shrinkage (R p = .91 and SEE p = 3.63 mL·kg -1· min -1 ); thus, this model should yield acceptable accuracy when applied to an independent sample of adults (ages 18–-65 years) with a similar cardiorespiratory fitness level. Based on standardized β-weights, the PFA variable (0.41) was the most effective at predicting VO2max followed by age (-0.34), gender (0.33), BMI (-0.27), and PA-R (0.16). This study provides a N-EX regression model that yields relatively accurate results and is a convenient way to predict VO2max in adult men and women. 相似文献

In this article we report a 3-yr study of a large-enrollment Cell Biology course focused on developing student skill in scientific reasoning and data interpretation. Specifically, the study tested the hypothesis that converting the role of exams from summative grading devices to formative tools would increase student success in acquiring those skills. Traditional midterm examinations were replaced by weekly assessments administered under test-like conditions and followed immediately by extensive self, peer, and instructor feedback. Course grades were criterion based and derived using data from the final exam. To alleviate anxiety associated with a single grading instrument, students were given the option of informing the grading process with evidence from weekly assessments. A comparative analysis was conducted to determine the impact of these design changes on both performance and measures of student affect. Results at the end of each year were used to inform modifications to the course in subsequent years. Significant improvements in student performance and attitudes were observed as refinements were implemented. The findings from this study emphasized the importance of prolonging student opportunity and motivation to improve by delaying grade decisions, providing frequent and immediate performance feedback, and designing that feedback to be maximally formative and minimally punitive. 相似文献

Although comprehensive and ecological approaches to early childhood prevention are commonly advocated, there are few examples of long-term follow-up of such programs. In this monograph, we investigate the medium- and long-term effects of an ecological, community-based prevention project for primary school children and families living in three economically disadvantaged neighborhoods in Ontario, Canada. The Better Beginnings, Better Futures (BBBF) project is one of the most ambitious Canadian research projects on the long-term impacts of early childhood prevention programming to date. Bronfenbrenner's ecological model of human development informed program planning, implementation, and evaluation. Using a quasi-experimental design, the BBBF longitudinal research study involved 601 children and their families who participated in BBBF programs when children were between 4 and 8 years old and 358 children and their families from sociodemographically matched comparison communities. We collected extensive child, parent, family, and community outcome data when children were in Grade 3 (age 8–9), Grade 6 (age 11–12), and Grade 9 (age 14–15). The BBBF mandate was to develop programs that would positively impact all areas of child's development; our findings reflect this ecological approach. We found marked positive effects in social and school functioning domains in Grades 6 and 9 and evidence of fewer emotional and behavioral problems in school across the three grades. Parents from BBBF sites reported greater feelings of social support and more positive ratings of marital satisfaction and general family functioning, especially at the Grade 9 follow-up. Positive neighborhood-level effects were also evident. Economic analyses at Grade 9 showed BBBF participation was associated with government savings of $912 per child. These findings provide evidence that an affordable, ecological, community-based prevention program can promote long-term development of children living in disadvantaged neighborhoods and produce monetary benefits to government as soon as 7 years after program completion. 相似文献

The aim of this study was to evaluate the reliability of two long jump tasks and their ability to predict 10 m sprint performance in elite adolescent female athletes. Eight junior national-level female track and field athletes completed three standing (SLJ) and reactive long jumps (RLJ) on portable force plates, followed by three 10 m sprints. Intra-class correlation coefficients (ICC) and coefficients of variation (CV) were calculated to examine reliability. Linear regression results identified the best predictor of average and best 10 m sprint time from the jump kinematic and kinetic measures. The ICCs and CVs indicated good reliability for the majority of kinetic measures however, better reliability was reported for the SLJ. The SLJ was a good predictor of best and average 10 m sprint time, with average horizontal power the best predictor of performance (best; R2 = 0.751, p = 0.003, Standard Error of Estimate (SEE)% = 2.2 average; R2 = 0.708, p = 0.005, SEE% = 2.5). 相似文献

The U.S. government has become increasingly focused on school climate, as recently evidenced by its inclusion as an accountability indicator in the Every Student Succeeds Act. Yet, there remains considerable variability in both conceptualizing and measuring school climate. To better inform the research and practice related to school climate and its measurement, we leveraged item response theory (IRT), a commonly used psychometric approach for the design of achievement assessments, to create a parsimonious measure of school climate that operates across varying individual characteristics. Students (n = 69,513) in 111 secondary schools completed a school climate assessment focused on three domains of climate (i.e., safety, engagement, and environment), as defined by the U.S. Department of Education. Item and test characteristics were estimated using the mirt package in R using unidimensional IRT. Analyses revealed measurement difficulties that resulted in a greater ability to assess less favorable perspectives on school climate. Differential item functioning analyses indicated measurement differences based on student academic success. These findings support the development of a broad measure of school climate but also highlight the importance of work to ensure precision in measuring school climate, particularly when considering use as an accountability measure. 相似文献
