A new approach to moral education using blended learning has been developed. This approach involves 10 scenarios that are designed as a web-based game and serves as a basis for group moral-consequence-based reasoning, which is developed based on a hypothetical-deductive model. The aim of the study was to examine the changes in students' blended learning interest and reasoning ability in a time series experimental design. After playing the game with the 10 initial scenarios during the first week of the study, participants were subjected to five blended learning sessions that required them to discuss the consequences of one of the 10 scenarios using hypothetical-deductive reasoning. After six weeks, the data from the 110 participants were analyzed using time series statistics. The results indicated that players were highly interested in the game, although their interest had a tendency to decrease slightly over time. Repetitive game play (i.e. practice) was positively associated with the players' moral reasoning performance. The study results may lend support to the design of a game with additional or more highly complex content for players to further develop students' consequential reasoning ability. 相似文献

This article presents a mixed-methods case study of Diego, a bilingual teen who completed public school in Florida. During adolescence, Diego negotiated multiple identities: successful student, Mexican American, bilingual, and typical U.S. teenager. Diego provided interviews and bilingual (English/Spanish) writing (narrative/expository) in 2008 (at age 12, Grade 6) and in 2012 (at age 16, Grade 10). A qualitative analysis of his interviews and a quantitative linguistic analysis of his writing reveal central elements of Diego’s language development as related to academic English and identity. Educational implications for working with bilingual adolescents are discussed. 相似文献

PTEN(Phosphatase and tensin homologue deleted on chromosome 10)是10号染色体缺失,编码与张力蛋白和辅助蛋白同源磷酸酶的抑癌基因.自1997年被正式发现起,越来越多的研究者对其蛋白、生物学活性、参与信号转导途径、药物靶点等相关方面做了极为深入和广泛的研究.研究显示,PTEN可通过多种信号转导通路,广泛参与人类肿瘤细胞的增殖、恶变、趋化、粘附、血管生成、凋亡、耐药、衰老、肌肉收缩、DNA损伤应答等过程,从而在人类肿瘤的治疗中发挥至关重要的作用,成为肿瘤生物学发展中最为重要的分子之一.迄今为止,涉及PTEN功能的相关临床试验已在肿瘤治疗中取得突破性进展,包括在白血病中的应用.但是国内外对于PTEN与白血病发生、进展、治疗的相关性并无针对性的、较为完善的归纳与总结.本综述结合近年来较为前沿的论点对PTEN与白血病发生、发展与治疗相关进展进行阐述,为进一步的科研提供新的思路与展望. 相似文献

The present study investigated preservice teachers’ self‐efficacy in classroom management involving students with symptoms of Attention Deficit/Hyperactivity Disorder (ADHD). A total of 137 Chinese preservice teachers were randomly presented with one of four vignettes involving a student character with ADHD symptoms, with manipulations including the character’s gender and diagnostic label of ADHD. Upon reading the vignette, participants responded to questions concerning their self‐efficacy in inclusive classroom management involving the character. Findings based on analysis of covariance indicated an interaction effect of the vignette character’s gender and label on teachers’ self‐efficacy. Specifically, teachers perceived greater self‐efficacy in a classroom involving a girl with an ADHD label than in a classroom involving a girl with no label or a boy with a label. Findings enriched the literature concerning the roles of gender and label in preservice teachers’ self‐efficacy toward inclusive classroom management. 相似文献

In this paper we use data from household surveys of 12 Latin American countries to assess how teacher salaries compare to workers in other occupations. The results show great variability from one country to another, ranging from an apparent underpayment of teachers in Bolivia by 35% relative to the control group, and a respective overpayment of 65% in Colombia. However, when statistical controls are introduced for the differential education, hours worked and gender composition between teachers and the comparison group, much of the earnings differential between the two groups disappears. On the basis of this finding, we cannot support the position that teachers are either overpaid or underpaid. 相似文献
