This article describes a framework to help publishers decide whether they should develop and host their own proprietary online journal system, or whether they should outsource this activity. We also suggest a practical high‐level checklist for comparing journal systems.  相似文献

Middle grades science teachers need professional support in practice as they implement new inquiry-based science. Professional development schools can provide this bottom-up support through connecting preservice and inservice teacher education programs in classroom practice. In this study, coteaching arrangements with secondary science education majors provided additional teachers in the classroom to support a materials-rich curriculum and the needed associated pedagogies. Science education majors provided needed assistance in troubleshooting difficulties with the new curriculum. They also provided needed content knowledge to support inquiry, along with creating moments and space for teachers to reflect on inquiry practice. Ongoing assistance by preservice teachers allowed inservice teachers to progress from logistical concerns in implementing kit curriculum to concerns regarding student learning and the supporting professional development.

The current study examines the effects of digital scaffolding on the English literacy of fourth- and sixth-grade students. A total of 1085 native English-speaking and language minority students from 25 treatment classes and 20 control classes across three school districts participated in this study for one school year. Treatment students read their English language arts and social studies text in visual-syntactic text format (VSTF) on their laptops and control students read the regular block format of the textbook either on their laptops or in print. Observations and interviews revealed that VSTF reading facilitated instruction processes and student learning in reading activities. The results of California Standard Tests (CST) before and after the treatment revealed that sixth-graders who received syntactic scaffolding outperformed control students on the composite CST score. In particular, reading in VSTF benefited the treatment students in three CST sub-categories: word analysis, written conventions and writing strategies. This study suggests that future research should investigate instructional strategies that support reading and writing development of adolescents, including at-risk students, using syntactic scaffolding.  相似文献

This study examines crossover effects of adolescent substance misuse preventive interventions on academic success in college. It evaluates pathways of influence on college grades, via effects on school engagement, problem-solving skills, and substance misuse in high school. Data were collected as part of an Randomized Controlled Trial (RCT) evaluating a multicomponent intervention conducted in 28 school districts with middle school students. At age 19, study participants (N = 1,488) enrolled in college reported on college grades. The model fit the data, supporting hypothesized pathways of intervention impacts. Inclusion of a significant direct effect on college grades further improved model fit. Results support the potential for universal substance misuse preventive interventions delivered by community partnerships during middle school to yield effects on long-term academic success.  相似文献

The study of childhood stress provides a useful perspective for assessing children's emotional status. Thematic projective techniques, like the Children's Apperception Test (CAT), may be useful in exploring children's perception of stress. For this purpose, a need-threat analysis is recommended to identify those underlying needs and threats that are likely to make a particular event or situation important, and hence potentially stressful, to an individual child. This paper introduces a scoring system for the CAT based on the analysis of thematic data in terms of five need-threat binaries, which serve as scoring categories. Preliminary data on reliability are presented.  相似文献

This study investigated the validity and reliability of the GymAware PowerTool (GPT). Thirteen resistance trained participants completed three visits, consisting of three repetitions of free-weight back squat, bench press, deadlift (80% one repetition maximum), and countermovement jump. Bar displacement, peak and mean velocity, peak and mean force, and jump height were calculated using the GPT, a three-dimensional motion capture system (Motion Analysis Corporation; 150 Hz), and a force plate (Kistler; 1500 Hz). Least products regression were used to compare agreeability between devices. A within-trial one-way ANOVA, typical error (TE; %), and smallest worthwhile change (SWC) were used to assess reliability. Regression analysis resulted in R2 values of >0.85 for all variables excluding deadlift mean velocity (R2 = 0.54–0.69). Significant differences were observed between visits 3-2 for bench press bar displacement (0.395 ± 0.055 m; 0.383 ± 0.053 m), and deadlift bar displacement (0.557 ± 0.034 m; 0.568 ± 0.034 m). No other significant differences were found. Low to moderate TE (0.6–8.8%) were found for all variables, with SWC ranging 1.7–7.4%. The data provides evidence that the GPT can be used to measure kinetic and kinematic outputs, however, care should be taken when monitoring deadlift performance.  相似文献
