基于计算思维的任务驱动式教学模式的研究

计算思维是当前国际计算机界广为关注的一个重要概念,也是当前计算机教育需要重点研究的重要课题。文章首先结合任务驱动式教学和教学模式的特点构建了基于计算思维的任务驱动式教学模型(Task-Driven Teaching Model Based on Computational Thinking,简称TDTMCT)。TDTMCT模型将教学者和学习者之间通过任务连接起来,教学过程以任务为主线,教学者主导,学习者主体。整个过程教学者运用计算思维方法准备课程,设计任务,学习者根据教学者的引导,运用计算思维方法完成教学任务。最后运用实例验证了该模型的可行性和高效性。与传统的教学模式相比较,基于计算思维的任务驱动式教学模式在培养学习者自我建构知识以及创新思维能力方面有较大的进步,不仅可以提高学习效率,而且可以培养学习者的计算思维能力。     

高校排课多元优化策略与自动实现方法的研究

通过分析高校排课需求,提出高校排课诸多优化与合理性要求:包括排课时间、学生班级、教师、教室等相关的多项合理性原则,以及最佳时间间隔均度、最佳时间分布均度、最大耦合度、最小流动值、最大利用率等指标。将排课过程进行分类分步骤实现,每类课程有各自的排入优先次序和排入时间段,通过循环给出有限的合理时间模式、进行耦合匹配检测、多级回溯等方法实现各类课程的自动排课,最后再进行补排、调整,使排课结果更合理。     

Helping Homeless Families Overcome Barriers to Successful Functioning

The author articulates key stressors in the lives of families who are homeless. These stresses often combine with barriers such as lack of job opportunities and/or insensitive professionals. Strategies for helping homeless families overcome these barriers and related issues are presented.     

Modelling parenting styles,moral intelligence,academic self-efficacy and learning motivation among adolescents in grades 7–11

The current study investigated the associations between three maternal and paternal parenting styles, moral intelligence, academic self-efficacy and learning motivation in three serial mediation models. Omani adolescents enrolled in 7th to 11th grades (N = 296) responded to an online survey containing demographic items and scales measuring the variables noted above. Results of Path Analysis indicated that the three models had a good overall fit. In detail, the three paternal styles (authoritative, authoritarian and permissive) had direct associations with moral intelligence and indirect associations with learning motivation. However, only two maternal parenting styles (i.e., authoritative and authoritarian) correlated directly with learning motivation and these two styles did not associate with moral intelligence. All effects were in the hypothesized direction except the effect of authoritative maternal and paternal styles. Moral intelligence had a positive direct correlation with students’ academic self-efficacy and learning motivation. Moral intelligence also mediated the negative associations between three types of fathers’ parenting styles and students’ motivation. Academic self-efficacy had a positive association with students’ motivation. These findings provided useful insights about the various association between external factors (e.g., parenting styles), internal factors (i.e., moral intelligence and self-efficacy) and students’ motivation among adolescents in middle and high schools.

20世纪社会主义运动的突出特征

社会主义的现实运动构成了20世纪社会历史画卷的主页，并在其矛盾运动进程中呈现出如下特点：理论与实践的历史错位是20世纪社会主义运动发端的主要特点；20世纪社会主义运动是曲折性与前进性、单一性与多样性的矛盾统一；在理论的创新性与教条化的矛盾撞击中不断发展。     

246例体检儿童超重或肥胖与血脂异常调查

目的调查苏北地区儿童的体质指数(BMI)水平和血脂水平,探讨儿童的超重或肥胖与血脂异常的关系。方法统计分析246例体检儿童的BMI指数和血脂水平,以BMI指数水平将246例体检儿童分为正常组和超重或肥胖组,比较两组间多种血脂水平异常的发生率。结果本地区儿童的血脂水平:TC 3.65±0.61 mmol/L,TG 0.96±0.41mmol/L,LDL-C 1.82±0.57 mmol/L,HOL-C 1.47±0.32 mmol/L。BMI水平17.1±2.5。超重或肥胖组血脂异常的发生率:TC 20.0%,TG 53.3%,LDL-C 33.3%,三种血脂水平异常的发生率均显著高于正常组(P<0.01)结论在进行心脑血管疾病早期预防时,应将肥胖或超重儿童这一群体作为重点干预对象,积极预防和治疗肥胖或超重儿童的血脂异常。
