Examining the relationship between grit and academic achievement within K‐12 and higher education: A systematic review

In recent years, grit has drawn increasing attention from both researchers and practitioners. As an important noncognitive indicator, grit has been used to understand individual success and performance in various fields. However, past empirical research has shown inconsistent findings on the relationship between grit and academic achievement. This study aims to review and synthesize past empirical findings on the relationship between grit and academic achievement. Forty‐four relevant articles involving a total of 60,133 participants met the inclusion criteria and were synthesized in this meta‐analysis. Our findings suggest that (a) overall grit level and its two facets (consistency of interest and perseverance of effort) are positively associated with academic achievement; (b) the association between grit and academic achievement is moderated by grade level; and (c) perseverance of effort shows the largest effect size on students’ academic achievement when compared with overall grit level and consistency of interest.     

Global changes of 5-hydroxymethylcytosine and 5-methylcytosine from normal to tumor tissues are associated with carcinogenesis and prognosis in colorectal cancer

Aberrant DNA methylation has raised widespread attention in tumorigenesis. In this study, we aimed to investigate the changes of global DNA methylation and hydroxymethylation from normal to tumor tissues in colorectal cancer (CRC) and their association with the prognosis. The levels of genomic 5-hydroxymethylcytosine (5hmC) and 5-methylcytosine (5mC) in cancerous tissues were significantly lower than those in corresponding adjacent normal tissues. The genomic levels of 5mC were significantly positively correlated with 5hmC in normal and cancerous tissues (all P<0.05). The ratio of 5mC in cancerous tissues to matched normal tissues (C/N-5mC) was also significantly positively correlated with the ratio of 5hmC in cancerous tissues to matched normal tissues (C/N-5hmC) (P=0.01). The 5mC levels and C/N-5mC ratios decreased with age (all P<0.05). Higher 5mC and 5hmC levels were found in rectal than in colon tissues (all P<0.05). High levels of 5mC in cancerous tissues and high C/N-5hmC ratios were each associated with lymph node metastasis (all P<0.05). Survival analysis indicated that the C/N-5mC ratio (P=0.04) is an independent protective factor for overall survival. The data showed that patients with a combination of high C/N-5hmC and low C/N-5mC ratios tended to have a worse prognosis (P<0.01). Our findings showed that the C/N-5mC ratio may be an independent prognostic factor for CRC outcome. Patients with both a high C/N-5hmC ratio and a low C/N-5mC ratio exhibited the worst survival, suggesting that 5mC and 5hmC can be used as critical markers in tumorigenesis and prognosis estimation.

马克思主义理论发展路径的几点思考

当代马克思主义理论发展主要有三条路径：回归文本、借鉴西方学者的研究、面向时代和实践。在三种路径中，回到文本是前提，借鉴西方是参照，面向实践是根本。当前马克思主义理论发展亟需解决的问题之一，是超越路径依赖，实现不同研究路径的互补，使三种路径之间既保持一种必要的张力而并行发展，又相互借鉴和补充。实践路径是马克思主义理论发展的主渠道，为此，特别需要确立研究的主体意识、问题意识和超越意识。     

Teachers’ socio-spatial practice in innovative learning environments

ABSTRACT

Understanding the relationship between innovative learning spaces and teachers’ pedagogical and social practices is essential given the increasing investment in innovative learning spaces worldwide. This study examined the socio-spatial practices of a group of teachers at a secondary school in an innovative learning space. Interview responses from 21 teachers revealed that space and social practices co-became through the interplay of the school culture, the physical, social and curriculum structures, and individual teachers’ sense-making of the practice. The study found that the cultural and structural systems drove the initial becoming of social practices, and that the individual systems shaped the diversified nature of the becoming. The findings suggest the importance of supporting teachers’ sense-making in terms of conceptions of subject teaching, professional identity, the affordances and constraints of the space and confidence in and capacity of constructing and managing effective learning experience in the space, when effecting educational changes with space.

Detecting Nonadditivity in Single‐Facet Generalizability Theory Applications: Tukey's Test

Under the generalizability‐theory (G‐theory) framework, the estimation precision of variance components (VCs) is of significant importance in that they serve as the foundation of estimating reliability. Zhang and Lin advanced the discussion of nonadditivity in data from a theoretical perspective and showed the adverse effects of nonadditivity on the estimation precision of VCs in 2016. Contributing to this line of research, the current article directs the discussion of nonadditivity from a theoretical perspective to a practical application and highlights the importance of detecting nonadditivity in G‐theory applications. To this end, Tukey's test for nonadditivity is the only method to date that is appropriate for the typical single‐facet G‐theory design, in which a single observation is made per element within a facet. The current article evaluates the Type I and Type II error rates of Tukey's test. Results show that Tukey's test is satisfactory in controlling for falsely detecting nonadditivity when the data are actually additive and that it is generally powerful in detecting nonadditivity when it exists. Finally, the article demonstrates an application of Tukey's test in detecting nonadditivity in a judgmental study of educational standards and shows how Tukey's test results can be used to correct imprecision in the estimated VC in the presence of nonadditivity.     

浅谈师爱

只有“亲其师”才能“信其道”，教师只有多给学生一些“爱”，才能用“爱”激发“爱”。在教育学生的过程中，“爱”学生要掌握好温和与严厉的尺度，还要关注学生的个性和心理特征。作为一名人类灵魂的工程师，就应该给予学生更多的爱。
