Global Learning and Observations to Benefit the Environment (GLOBE) is an international environmental education and science partnership which coordinates the work of students (aged 5 to 18), teachers and scientists from 48 countries on five continents to study and better understand the global environment. Accurate ground reference data is fundamental to the use of remotely sensed data for land cover classification and mapping. Because very little ground reference data has been collected, the accuracy of many land cover maps may be questioned, thus accurate land cover ground reference data is an important need that could be addressed through GLOBE scientist-student collaboration. If earth systems scientists are to use student data, it is important that those data be as accurate as possible to ensure reliability of research results. Thus a key question for this research is whether student collected data are accurate enough to support rigorous scientific investigations. This paper describes results of the GLOBE Science-Education Team on Data Validation and Accuracy Assessment's collaboration with teachers and students to: (1) design and test the pre-protocol learning activities; (2) test the protocols intended to guide the collection and analysis of data; and (3) implement the learning activities and protocols to determine the relative accuracy of student collected versus professionally collected land cover data. To ensure the most accurate classification of land cover possible, a new international hierarchical land cover classification system, the Modified Unesco Classification (MUC) system was developed. GLOBE Data Collection Protocols and methods were designed and implemented to test the accuracy of student collected reference data were designed and implemented. Students who collected land cover reference data using GLOBE protocols, obtained data which are at least as accurate as that collected by professionals.  相似文献

Making the grade: teacher training for inclusive education: A systematic review     

Lauren Tristani  Rebecca Bassett‐Gunter 《Journal of Research in Special Educational Needs》2020,20(3):246-264

The role of teacher training, as it pertains to the adoption of inclusive education (IE) (European Journal of Special, 22, 2007, 367), is critical in realizing and achieving truly IE environments. Literature often reports poor or inadequate training with regard to IE practices (Preparing Teachers of the Deaf for a Complex, Jacksonville, FL). The purpose of this review was to examine North American and Australian research regarding teacher training for students with disabilities (SWD) with the goal of informing best practice. Of the 27 reviewed studies, teacher training interventions reported positive outcomes and showed improvements in the areas of teachers’ attitudes/perceptions, knowledge, and strategies/skill development (Teacher Education and Special Education: The Journal of the Teacher Education Division of the Council for Exceptional Children, 32, 2009, 166) regarding IE SWD. The researchers cautiously recommend the employment of workshop style approaches as they appear to have the capacity to tackle all three outcome variables concurrently and within the shortest timeframe. Our restrained recommendations for best practice are born out of the quality of evidence presented within the reviewed studies.  相似文献

Promoting intercultural friendship among college students     

Elisabeth Gareis  Jeffrey Goldman  Rebecca Merkin 《Journal of International and Intercultural Communication》2019,12(1):1-22

This study assessed the efficacy of a semester-long buddy project in facilitating intercultural friendship development. Results of pre-, post-, and follow-up surveys show significant improvements in knowledge and attitude; correlations between post-project knowledge, attitude, and interest in continued contact; and correlations between interest in continued contact and actual contact in the follow up. The majority of the participants evaluated the project as effective for friendship formation. Of the follow-up respondents, 23% developed friendships with their former buddies. The project serves as an example for assignments with the potential for friendship development, which is essential for optimal intergroup contact.  相似文献   

Learning to Lead: an Approach to Mathematics Teacher Leader Development

This paper describes a partnership between a university and an urban school district, formed with a goal of preparing mathematics teacher leaders to conduct professional development (PD) at their schools. The university and district partners worked together to achieve the district’s mission of providing every student with high-quality instruction and equitable learning opportunities in mathematics by building the district’s capacity to conduct school-based PD for mathematics teachers. Given the power of school-based subject-specific PD for improving instructional quality, we worked with Teacher Leaders from participating schools to prepare and support them to lead PD workshops at their schools. In this paper, we examine how Teacher Leaders learn and adapt key elements of a PD model over three school years through the lenses of Prediger et al.’s Three-Tetrahedron-Model (2019) and the university’s Learning to Lead model. Over 3 years, we see that Teacher Leaders use the key structures of the PD model; make adaptations in response to school goals, interests, and priorities; and gain confidence in their work with colleagues. By viewing the adaptations through the lens of pedagogies of practice as well as the relationships illustrated by the 3-T model, this work offers insights into the complexities of teacher leadership development.

Parent Support for Children’s Physical Activity: A Qualitative Investigation of Barriers and Strategies     

Rebecca Bassett-Gunter  Ryan Rhodes  Shane Sweet  Lauren Tristani  Yasaman Soltani 《Research quarterly for exercise and sport》2017,88(3):282-292

Purpose: Parents play an important role in supporting children’s physical activity (PA) behavior. Parent PA support is a behavior unto itself that has been examined within the framework of an adapted theory of planned behavior (TPB). The primary purpose of this research was to identify key barriers to parent PA support to understand perceptions of control in relation to parent PA support. The second purpose of this research was to identify potential strategies to enhance parent PA support via enhanced perceived behavioral control. Method: Focus groups were conducted with parents (N = 21) of children aged 5 to 11 years old. A deductive content analysis was employed to analyze the data guided by an adapted TPB. Results: Themes related to barriers included parents’ motivation, affective experiences in providing PA support, and control factors (e.g., cost, time, safety concerns, screen). Themes related to potential strategies included opportunities for participation and improved affective experiences for parents, community parenting, and self-regulatory strategies. Conclusion: The identification of specific barriers to parent PA support can guide the development of interventions to facilitate parent PA support. Informational, programming, and self-regulatory training interventions may be useful in enhancing parent support.  相似文献   

The characterization of commercial artists’ alkyd paints     

Rebecca Ploeger  Dominique Scalarone  Oscar Chiantore   《Journal of Cultural Heritage》2008,9(4):412-419

There is little information in the conservation literature with respect to artists’ alkyd paints; thus, artists and conservators are somewhat at a loss about how to use and treat alkyds. Recently, analytical methods have been developed to identify the components in these polymers (oil modified polyesters), rates of cross-linking and mechanical properties. Presented in this paper are some of the characterization results of artists’ alkyd paints using THM (thermally assisted hydrolysis and methylation) gas chromatography– mass spectrometry (THM–GC/MS) and Fourier transform infrared spectroscopy–attenuated total reflectance (FTIR–ATR). Four brands of artists’ alkyd paints containing alkyd resin have been analysed; one containing a phthalic anhydride and pentaerythritol based alkyd resin, two containing isophthalic acid and pentaerythritol based alkyd resins, and the final one containing both phthalic anhydride and isophthalic acid and pentaerythritol based resins among the colours studied.  相似文献   

Comparison of physiological responses to graded exercise test performance in outrigger canoeing     

Kerr RM  Spinks W  Leicht AS  Sinclair W  Woodside L 《Journal of sports sciences》2008,26(7):743-749

The aim of this study was to establish a graded exercise test protocol for determining the peak physiological responses of female outrigger canoeists. Seventeen trained female outrigger canoeists completed two outrigger ergometer graded exercise test protocols in random order: (1) 25 W power output for 2 min increasing by 7.5 W every minute until exhaustion; and (2) 25 W power output for 2 min increasing by 15 W every 2 min to exhaustion. Heart rate and power output were recorded every 15 s. Expired air was collected continuously and sampled for analysis at 15-s intervals, while blood lactate concentration was measured immediately after and 3, 5, and 7 min after exercise. The peak physiological and performance variables examined included peak oxygen uptake (VO2peak), minute ventilation, tidal volume, ventilatory thresholds 1 and 2, respiratory rate, respiratory exchange ratio, heart rate, blood lactate concentration, power output, performance time, and time to VO2peak. There were no significant differences in peak physiological responses, ventilatory thresholds or performance variables between the two graded exercise test protocols. Despite no significant differences between protocols, due to the large limits of agreement evident between protocols for the peak physiological responses, it is recommended that the same protocol be used for all comparison testing to minimize intra-individual variability of results.  相似文献   

Correlating Spatial Ability With Anatomy Assessment Performance: A Meta-Analysis     

Victoria A. Roach  Misa Mi  Jason Mussell  Sonya E. Van Nuland  Rebecca S. Lufler  Kathryn M. DeVeau  Stacey M. Dunham  Polly Husmann  Hannah L. Herriott  Danielle N. Edwards  Alison F. Doubleday  Brittany M. Wilson  Adam B. Wilson 《Anatomical sciences education》2021,14(3):317-329

Interest in spatial ability has grown over the past few decades following the emergence of correlational evidence associating spatial aptitude with educational performance in the fields of science, technology, engineering, and mathematics. The research field at large and the anatomy education literature on this topic are mixed. In an attempt to generate consensus, a meta-analysis was performed to objectively summarize the effects of spatial ability on anatomy assessment performance across multiple studies and populations. Relevant studies published within the past 50 years (1969–2019) were retrieved from eight databases. Study eligibility screening was followed by a full-text review and data extraction. Use of the Mental Rotations Test (MRT) was required for study inclusion. Out of 2,450 screened records, 15 studies were meta-analyzed. Seventy-three percent of studies (11 of 15) were from the United States and Canada, and the majority (9 of 15) studied professional students. Across 15 studies and 1,245 participants, spatial ability was weakly associated with anatomy performance (r_pooled = 0.240; CI at 95% = 0.09, 0.38; P = 0.002). Performance on spatial and relationship-based assessments (i.e., practical assessments and drawing tasks) was correlated with spatial ability, while performance on assessments utilizing non-spatial multiple-choice items was not correlated with spatial ability. A significant sex difference was also observed, wherein males outperformed females on spatial ability tasks. Given the role of spatial reasoning in learning anatomy, educators are encouraged to consider curriculum delivery modifications and a comprehensive assessment strategy so as not to disadvantage individuals with low spatial ability.  相似文献
