As a core component of most cognitive diagnosis models, the Q-matrix, or item and attribute association matrix, is typically developed by domain experts, and tends to be subjective. It is critical to validate the Q-matrix empirically because a misspecified Q-matrix could result in erroneous attribute estimation. Most existing Q-matrix validation procedures are developed for dichotomous responses. However, in this paper, we propose a method to empirically detect and correct the misspecifications in the Q-matrix for graded response data based on the sequential generalized deterministic inputs, noisy ‘and’ gate (G-DINA) model. The proposed Q-matrix validation procedure is implemented in a stepwise manner based on the Wald test and an effect size measure. The feasibility of the proposed method is examined using simulation studies. Also, a set of data from the Trends in International Mathematics and Science Study (TIMSS) 2011 mathematics assessment is analysed for illustration.  相似文献

ABSTRACT

The demands and expectations placed on counselors-in-training can make them susceptible to stress, burnout, and poor school-life balance. Therefore, counseling students could benefit from learning mindfulness techniques as self-care strategies that promote increased relaxation, coping, and stress prevention. This mixed-methods study examined graduate counseling students’ perceptions of mindfulness training to determine its impact on self-efficacy, mood, stress, and other areas of wellness. Participants reported enhanced relaxation, increased awareness of the need for self-care, better understanding of the connection between mindfulness and overall well-being, and an impact of mindfulness on other areas of their lives.  相似文献

Working memory training is widely used transdiagnostically to improve cognition. However, more recently, studies using working memory training packages have targeted emotion‐regulation outcomes to determine whether far transfer effects can be achieved. A narrative review is conducted of studies that have used standardized computerized working memory training packages across healthy volunteers, affect, anxiety, post‐traumatic stress disorder (PTSD), and eating disordered populations with emotion‐regulation outcomes. Working memory training has been used in children, adolescents, and adults to improve emotion regulation. Many studies have reported gains in mood as well as emotion‐regulation strategies following working memory training, regardless of clinical indication and whether near transfer gains were achieved in cognitive domains. Significant emotion‐regulation outcomes include: state and trait anxiety, rumination, brooding, positive appraisal, decreasing maladaptive emotion‐regulation strategies, and decreasing intrusive thoughts. It is speculated that these far transfer outcomes from working memory training are possible due to the cognitive and neural overlap between cognitive and affective working memory, and emotion regulation. Working memory training could improve cognitive efficiency, which, in turn, increases the availability of cognitive resources during times when emotion regulation is taxed. Future studies need to consider the role of participant expectancy in predicting outcome measure performance, and including subjective and objective outcomes is paramount to study design. Furthermore, sample sizes require additional attention, given that the current review highlights that individual differences in non‐clinical and clinical populations influence the outcomes from working memory training. Working memory training offers a possibility for improving emotion regulation transdiagnostically.  相似文献

Previous studies have documented that the perception of self‐motion direction can be extracted from the patterns of image motion on the retina (also termed optic flow). Self‐motion perception remains stable even when the optic‐flow information is distorted by concurrent gaze shifts from body/eye rotations. This has been interpreted that extraretinal signals—efference copies of eye/body movements—are involved in compensating for retinal distortions. Here, we tested an alternative hypothesis to the extraretinal interpretation. We hypothesized that accurate self‐motion perception can be achieved from a purely optic‐flow‐based visual strategy acquired through experience, independent of extraretinal mechanism. To test this, we asked human subjects to perform a self‐motion direction discrimination task under normal optic flow (fixation condition) or distorted optic flow resulted from either realistic (pursuit condition) or simulated (simulated condition) eye movements. The task was performed either without (pre‐ and posttraining) or with (during training) the feedback about the correct answer. We first replicated the previous observation that before training, direction perception was greatly impaired in the simulated condition where the optic flow was distorted and extraretinal eye movement signals were absent. We further showed that after a few training sessions, the initial impairment in direction perception was gradually improved. These results reveal that behavioral training can enforce the exploitation of retinal cues to compensate for the distortion, without the contribution from the extraretinal signals. Our results suggest that self‐motion perception is a flexible and adaptive process which might depend on neural plasticity in relevant cortical areas.  相似文献

The authors examine how the cognitive complexity domains of differentiation and integration are uniquely cultivated by constructivist and phenomenological teaching practices, respectively. Implications are explored in terms of reflective practices and proposed phenomenological activities that support concept deconstruction and empathy development as a means to grow integrative complexity.  相似文献

Contextualization has featured prominently in missiological research for decades, often alongside concepts such as syncretism and hybridity. Being typically conceived as attempts to transpose and communicate the gospel in words and ways that make sense to people in their local cultural settings, contextualization has been theorized extensively in missiological scholarship. Notwithstanding this longstanding scholarly interest, a dearth of research recognizes in-service training as a valid expression of contextualization praxis. This article addresses this knowledge gap. Set in the contemporary church context in Thailand, the article explores questions, issues, and trends of current theological training practice, considering future opportunities for indigenous leadership formation. The analysis converges around the central proposition that in-service training is an under-recognized strategy for leadership development in Thailand and beyond. Conceptualizing opportunities for future research, the review charts pertinent perspectives and prospects for in-service training. This article embodies a timely research agenda aimed at sidestepping undue reliance on Western-dominated hermeneutics while at the same time advocating for indigenous theological training approaches in countries of the majority world.  相似文献
