Family Communication Patterns and Cognitive Processing: Conversation and Conformity Orientations as Predictors of Informational Reception Apprehension

This study examined the unique and combined associations among family communication patterns (i.e., conversation and conformity orientations) and young adult children's informational reception apprehension (IRA; i.e., listening anxiety and intellectual inflexibility). Participants included 592 young adult children from first-marriage and postdivorce families. Results indicated that family conversation orientations are inversely associated with listening anxiety and intellectual inflexibility, whereas conformity orientations are positively associated with both traits. Furthermore, an interaction effect between conversation and conformity orientations emerged, such that high-conformity orientations moderate (or reduce) the inverse association between family conversation orientations and young adults' listening anxiety. Among the more important implications in this study is the finding that family communication patterns have a small but meaningful association with individuals' information-processing skills.     

Effects of manipulating relative and absolute motion information during observational learning of an aiming task

In the visual perception perspective of observational learning, the manipulation of relative and absolute motion information in visual demonstrations optimally directs learners’ search towards appropriate task solutions. We assessed the effect of emphasizing transformational information and removal of structural information using point-light kinematic displays in approximating the model’s relative motion patterns. Participants viewed computer-simulated point-light demonstrations or normal video demonstrations before and intermittently throughout 100 acquisition trials with knowledge of results on an underarm modified-dart aiming task. On the next day, all participants performed 20 retention trials without demonstrations. The kinematics of spatial and temporal coordination and control variables were examined relative to the model’s action, as well as performance scores. The results indicated that approximation of the model’s spatial and temporal coordination and control patterns was achieved after observation of either type of demonstrations. No differences were found in movement outcomes. In a second experiment, the effects of manipulating absolute motion information by slowmotion demonstrations were examined relative to real-time demonstrations. Real-time demonstrations led to a closer approximation to the model’s spatial and temporal coordination patterns and better outcome scores, contradicting predictions that slow-motion displays convey intact relative motion information. We speculate that the effect of visual demonstration speed on action perception and reproduction is a function of task constraints ‐ that is, novelty or familiarity of relative motion of demonstrated activities.     

现代信息技术异化的根源分析及其消解的可能性

通过对教育领域现代信息技术异化现象的阐释和根源分析,给出技术与人的竞争关系是异化的直接根源,而导致异化产生的因素则可分为主体性原因和客体性原因两个方面。这两种因素在实践过程中都不可能完全消解,因此异化现象只能在一定的范围内弱化。经过论证分析给出了弱化的途径:树立合目的的教育观、技术价值观,在技术活动中凸显技术的人文关怀,使技术与人的关系重新回归和谐,使祛魅的现代信息技术走向返魅的后现代技术。

Teaching second-grade students to write sequential text

With the adoption of the English Language Arts Common Core State Standards, writing has become an increasingly important area of instruction. Moreover, there has been an increased sophistication in the types of writing required of young children and the use of textual evidence expected in student writing. Historically, children have not been routinely taught explicit strategies for writing, but have been exposed to less rigid writing instruction such as Writer's Workshop. The current study examined an explicit writing strategy, the Read-to-Write Strategy, to determine its effectiveness in teaching young children how to write sequential text. A single subject design (N = 40) was used to compare the writing of second graders before and after instruction. Results indicated that the Read-to-Write Strategy significantly increased the quality of sequential text from the pre- to post-instruction with a large effect size reported. Implications and recommendations for educators and researchers are provided.

XML完整性约束的实现

XML之所以在很短的时间内就获得广泛认同,成为一种被大量使用的通用的数据格式,是因为XML文档很容易表达来自不同源的数据,是实现数据集成和交换的重要方法。但是其所能表示的语义信息却相对有限。在已有的DTD和XMLschema规范的基础上进一步增强定义完整性约束的能力,对此进行了论述。
