AbstractComputer-based learning environments (CBLEs) provide unprecedented opportunities for personalized learning at scale. One such system, iSTART (Interactive Strategy Training for Active Reading and Thinking) is an adaptive, game-based tutoring system for reading comprehension. This paper describes how efforts to increase personalized learning have improved the system. It also provides results of a recent implementation of an adaptive logic that increases or decreases text difficulty based on students’ performance rather than presenting texts randomly. High school students who received adaptive text selection showed increased sense of learning. Adaptive text selection also resulted in greater pre-training to post-training comprehension test gains, especially for less-skilled readers. The findings demonstrate that system-driven, just-in-time support consistent with the goals of personalized learning benefit the efficacy of computer-based learning environments. 相似文献

This article describes a novel approach for using EndNote to manage and code references in the conduct and reporting of systematic reviews and scoping reviews. The process is simple and easy for reviewers new to both EndNote and systematic reviews. This process allows reviewers to easily conduct and report systematic reviews in line with the internationally recognized PRISMA reporting guidelines and also facilitates the overall task of systematic or scoping review conduct and reporting from the initial search through to structuring the results, discussion, and conclusions in a rigorous, reproducible, and user-friendly manner. 相似文献

In learning chemistry at the entry level, many learners labor under misconceptions about the subject matter that are so fundamental that they are typically never addressed. A fundamental misconception in chemistry appears to arise from an adding of existing phenomenal concepts to newly-acquired chemical concepts, so that beginning learners think of chemical entities as themselves having the very same ‘macro’ properties that we observe through the senses. Those who teach or practice chemistry never acquire these misconceptions because they were able to naturally pick up the nature of the subject to begin with. But as a result, they remain unaware of the foundational assumptions and understanding that they operate with and that many beginning learners persistently lack. Thus, a systematic picture of the workings of chemical theory as they relate to observable phenomena needs to be elucidated so that the attention of chemical educators is drawn to the fundamental understanding of the subject that they already possess and that beginning learners of chemistry lack, so that beginning learners can be given the opportunity to gain an understanding of how chemical explanations are in general related to observable phenomena. The ‘layered’ way in which chemical and physical entities are related to each other within chemical theory can also be clarified in this way. To afford this picture, the philosophical concepts of supervenience and emergence are explained and applied to chemistry, as philosophers of chemistry have already done. The result provides a model for teaching chemistry that, if consistently applied, has the potential to greatly enhance fundamental understanding of the subject matter. 相似文献

Purpose: Marital dissatisfaction and conflict often increase for couples after the birth of a child and are evident in fewer positive family interactions and more negative family interactions. Because exercise is known to increase positive emotions and decrease negative emotions, the current study examined the extent to which higher levels of mothers’ exercise during the postpartum period were related to more positive and fewer negative emotion-expressive behaviors with their infants’ fathers. Method: Mothers’ (N = 46; M = 8 months postpartum) positive and negative expressive behaviors were coded during couples’ discussions of current conflict and positive family experiences. Mothers self-reported their leisure-time exercise behavior. Results: First-time mothers and mothers with higher levels of leisure-time exercise behavior displayed higher levels of positive expressive behaviors during couples’ discussions. Conclusions: Exercise may be associated with increased positive emotion and, in turn, can have great potential to improve family relationships during the postpartum period when marital stress normatively increases, particularly for mothers with more than 1 child. Future longitudinal studies are needed to understand exercise patterns across the postpartum period to identify the most effective timing and optimal level of exercise that lead to more positive expressive behaviors. 相似文献

School Belonging,Ethnic Identity,and Psychological Adjustment Among Ethnic Minority College Students
This study considers how the psychological adjustment of ethnic minority college students may be linked to a sense of school belonging and ethnic identity, two constructs related to individuals feeling like they belong to a larger group. Using self-reports from 311 undergraduates from ethnic minority backgrounds, school belonging was found to be negatively associated with depressive symptoms, and positively associated with perceived self-worth, scholastic competence, and social acceptance, while ethnic identity was only found to be positively associated with self-worth. Furthermore, the interaction between ethnic identity and school belonging was significantly associated with self-worth, suggesting that in the absence of a sense of belonging at school, stronger ethnic identity was linked to higher self-worth. College students reported the lowest levels of self-worth when they were neither connected to their college nor connected to their ethnic group. 相似文献

Because of these learners’ potential as future leaders, it is imperative that educators develop gifted students’ ability to identify and solve complex social justice problems. Nourishing students’ affective traits, including empathy for others, understanding of themselves, and the ability to connect to others in local and global society, will help students to recognize and seek out authentic problems. This article examines the nuances around the creative problem-solving process and how educators can infuse the curriculum with opportunities to develop and strengthen the skills students need to become engaged, real-world problem seekers, as we call it, and problem solvers. Through the combination of social justice issues and creative problem seeking, students can be motivated to engage with the community and promote positive change in the world. 相似文献

Learning in today's classrooms can be disconnected from students' real world experiences. Providing students the opportunity to address real‐world problems may provide avenues for students to engage in their communities while developing academic skills and knowledge. Additionally, for students whose interests are piqued by the nature of their community's problems, these activities have the potential to offer students meaningful, motivating work in a supportive environment. This article explores how providing students with interest‐based service‐learning opportunities may help them develop and demonstrate gifted behaviors. In addition, methods for integrating student interests and service‐learning projects are presented. © 2012 Wiley Periodicals, Inc. 相似文献

- As the number of authors on scientific publications increases, ordered lists of author names are proving inadequate for the purposes of attribution and credit.
- A multi‐stakeholder group has produced a contributor role taxonomy for use in scientific publications.
- Identifying specific contributions to published research will lead to appropriate credit, fewer author disputes, and fewer disincentives to collaboration and the sharing of data and code.

Physical activity benefits for disease prevention are well-established. Smartphones offer a convenient platform for community-based step count estimation to monitor and encourage physical activity. Accuracy is dependent on hardware–software platforms, creating a recurring challenge for validation, but the Apple iPhone® M7 motion co-processor provides a standardised method that helps address this issue. Validity of the M7 to record step count for level-ground, able-bodied walking at three self-selected speeds, and agreement with the StepWatchTM was assessed. Steps were measured concurrently with the iPhone® (custom application to extract step count), StepWatchTM and manual count. Agreement between iPhone® and manual/StepWatchTM count was estimated through Pearson correlation and Bland-Altman analyses. Data from 20 participants suggested that iPhone® step count correlations with manual and StepWatchTM were strong for customary (1.3 ± 0.1 m/s) and fast (1.8 ± 0.2 m/s) speeds, but weak for the slow (1.0 ± 0.1 m/s) speed. Mean absolute error (manual–iPhone®) was 21%, 8% and 4% for the slow, customary and fast speeds, respectively. The M7 accurately records step count during customary and fast walking speeds, but is prone to considerable inaccuracies at slow speeds which has important implications for certain patient groups. The iPhone® may be a suitable alternative to the StepWatchTM for only faster walking speeds. 相似文献
