Idle chatter or compelling conversation? The potential of the social media-based #NGSSchat network for supporting science education reform efforts

The Next Generation Science Standards (NGSS) chat (#NGSSchat) is a social media-based professional network used to discuss topics related to the NGSS in the United States. While successful reforms involve and coordinate the work of multiple stakeholders, recent research points out a striking lack of coordination between the individuals working in different educational roles—to the detriment of intended changes in the system. In this study, we analyzed more than 7,000 posts from individuals participating in #NGSSchat on Twitter (n = 247) during 2 years of 1-hr synchronous discussions. We studied the depth and types of conversations that took place, the extent to which the involvement of teachers, administrators, researchers, and organizations was balanced, and what explains participation in the network over time. Using a mixed-methods approach involving social network analysis, we found that conversations were primarily transactional, or social, and substantive, or providing opportunities for sense-making about the standards or for participants to transform their practice and that individuals from diverse roles participated, with teachers comprising the plurality of those involved. Additionally, researchers, administrators, and teachers were the most active in the network, with no differences in both initiating, or sending, and being the recipients of, or receiving, replies as a part of conversations. Finally, we found that being a teacher or administrator, as well as receiving replies from individuals who were important in the network, were positively related to sustained involvement in the network in the following year. We discuss how #NGSSchat—as a social media-based professional network—demonstrates similar features in other effective networks, and how social media-based networks invite new visions for how to implement ambitious, large-scale changes in science education.  相似文献   

Embracing Death: Mexican Parent and Child Perspectives on Death     

Isabel T. Gutiérrez  David Menendez  Matthew J. Jiang  Iseli G. Hernandez  Peggy Miller  Karl S. Rosengren 《Child development》2020,91(2):e491-e511

A mixed-method approach was used to explore parent and child perspectives on death in Mexico. Parents’ and children’s death-related experiences and understanding of death were examined. While all children in this sample displayed a biological understanding of death, older children were less likely to endorse that all living things die. Children also displayed coexistence of beliefs related to death that can be attributed to both their biological and spiritual understanding of death. We also found that older children were more likely to report that a child should feel sad following the death of a loved one. These findings highlight how cultural practices shape the development of cognitive and affective processes related to death.  相似文献

Constructing a Universal Scale of High School Course Difficulty     

Dina Bassiri  E. Matthew Schulz 《Journal of Educational Measurement》2003,40(2):147-161

This study examined the usefulness of applying the Rasch rating scale model (Andrich, 1978) to high school grade data. ACT Assessment test scores (English, Mathematics, Reading, and Science Reasoning) were used as "common items" to adjust for different grading standards in individual high school courses both within and across schools. This scaling approach yielded an ACT Assessment-adjusted high school grade point average (AA-HSGPA) on a common scale across high schools and cohorts within a large public university. AA-HSGPA was a better predictor of first-year college grade point average (CGPA) than the regular high school grade point average. The best model for predicting CGPA included both the ACT composite score and AA-HSGPA.  相似文献   

The Efficacy of Eye Movement Desensitization and Reprocessing Therapy Technique in the Treatment of Test Anxiety of College Students     

Matthew Enright  Tracy D. Baldo  Scott D. Wykes 《Journal of College Counseling》2000,3(1):36-48

This study explored the efficacy of eye movement desensitization and reprocessing (EMDR) in the treatment of test anxiety. Thirty‐five college students with test anxiety were randomly assigned to either a treatment or delayed treatment control group. In this study, EMDR was shown to be effective in reducing overall test anxiety as well as “emotionality” and “worry” components of test anxiety.  相似文献   

An extinction cue reduces spontaneous recovery of a conditioned taste aversion     

Douglas C. Brooks  Matthew I. Palmatier  Eliseo O. Garcia  Jessica L. Johnson 《Learning & behavior》1999,27(1):77-88

The effect of an auditory cue presented during extinction on spontaneous recovery of a conditioned taste aversion was investigated in three experiments. Experiment 1 demonstrated that the presence of the cue during extinction did not influence saccharin consumption during that phase, and that an aversion to saccharin in the absence of the cue was stronger at 18 days than at 1 day after extinction, representing spontaneous recovery rather than a renewal effect. Experiment 2 showed that a cue presented during extinction and testing reduced spontaneous recovery. Experiment 3 replicated that effect and showed that it depended on the cue’s correlation with extinction and not on an unconditioned effect; cues that had been presented during or prior to conditioning did not reduce spontaneous recovery when presented during testing. The cue’s potential to reduce spontaneous recovery through conditioned inhibition or configural cue learning is discussed, as is the possibility that the cue retrieves a saccharin extinction memory in a manner consistent with Bouton’s (1993) account of spontaneous recovery.  相似文献   

Training Needs Analysis and Evaluation for New Technologies Through the Use of Problem‐based Inquiry     

Matthew Scott  Casey Dennis Doverspike 《Performance Improvement Quarterly》2005,18(1):110-124

ABSTRACT The analysis of calls to a help desk, in this case calls to a computer help desk, can serve as a rich source of information on the real world problems that individuals are having with the implementation of a new technology. Thus, we propose that an analysis of help desk calls, a form of problem‐based inquiry, can serve as a fast and low cost means of both analyzing training needs and evaluating training. We illustrate the use of problem‐based inquiry through a case study of the analysis of help desk calls made after the delivery of a training program that served to introduce a new type of document management system in a professional services firm. Based on the analysis of help desk calls it should be possible to modify future training so as to enhance transfer to the job environment.  相似文献   

Using mixed-methods,a data model and a computational ontology in film audience research     

Peter Merrington  Matthew Hanchard  Michael Pidd  Katherine Rogers  David Forrest 《Cultural Trends》2019,28(2-3):118-131

ABSTRACT

This paper discusses a methodology that seeks to address one of the challenges in working with a range of data in mixed-methods audience research, which is how to sort, order and categorise different data so that they can be systematically combined and interrogated. The methodology was developed as part of the “Beyond the Multiplex: audiences for specialised films in English regions” (BtM) project. This project required a mixed methods approach using surveys, interviews, focus groups and document analysis to explore the richness of audience experiences and trends in the context of regional film policy. This required a mixed methods approach using surveys, interviews, focus groups and document analysis. The project utilised a data model approach that uses the principles of a computational ontology in order to sort, order and categorise data for systematic interrogation. The paper discusses methods, data, coding, and the use of a data model to support data analysis. We argue that this approach enables the cross referencing of data that provides a rich, multi-layered and relational understanding of film audiences but requires time and attention to data management and coding. Although, additionally it also forms the basis of an open access data resource for future research.  相似文献   

Functional Movement ScreenTM total score does not present a gestalt measure of movement quality in youth athletes     

Matthew David Wright  Paul Chesterton 《Journal of sports sciences》2019,37(12):1393-1402

We aimed to evaluate the internal consistency and factor structure of the Functional Movement Screen (FMS^TM) in youth athletes and quantify differences between individual task score at different stages of maturation. FMS^TM and anthropometric variables were measured in 144 youth athletes (96 female, 48 male). Biological maturation was categorised as before- (<-0.5 years), at- (?0.49–0.50 years) and after- peak height velocity [PHV] (>0.51 years). Internal consistency was poor (Cronbach’s alpha; 0.53, ±90% confidence limit 0.10; ordinal alpha 0.6, ±0.09). Principle component analysis extracted two components, representing 47% of the total variance. Tasks loading highest on component 1 required stability, while those loading highest on component 2 favoured mobility. “Likely” decrements in component 1 tasks were observed before-PHV. In-line lunge (effect size ±90% confidence limit; ?0.47, ±0.49), hurdle step (?0.38, ±0.49), and trunk stability push-up (?0.51, ±0.45), were lower compared with athletes at-PHV and rotatory stability (?0.44, ±0.37) was lower than those after-PHV. Boys’ scored “most likely”, higher (0.73, ±0.28) in trunk stability push-up, and girls “likely” higher in shoulder mobility (0.46, ±0.29). In our population, the FMS^TM is not uni-dimensional, thus total score should be avoided. Clear maturation affects were observed in stability tasks.  相似文献
