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.

The Informational Text Structure Survey (ITS2): An exploration of primary grade teachers’ sensitivity to text structure in young children's informational texts

There has been no research reported about if or how well primary grade teachers can identify information text structures in children's authentic informational texts. The ability to do so accurately and reliably is a prerequisite for teachers to be able to teach students how to recognize and use text structures to assist them in comprehending informational texts. The authors report the development of the Informational Text Structure Survey (ITS²). Prior to training, primary grade teachers demonstrated low accuracy and reliability in identifying traditional expository text structures in well-structured children's grade level–appropriate informational texts. Results after training with the ITS² instrument showed significant improvements in the teachers’ accuracy and reliability in identifying traditional informational text structures in well-structured children's grade level–appropriate informational texts after training with the ITS² instrument.     

CLT and its Application in Oral English Classroom

Communicative Language Teaching (CLT) is beyond doubt the most advanced language teaching approach in the new era. Yet, it was treated coldly in China at the outset. After over two decades of reform and trial, Chinese educators become aware that CLT does not clash but complement with Chinese traditional teaching methods if used selectively and flexibly. To stimulate further research on adapting CLT appropriately to Chinese EFL classroom, the author hereby shares with all the measures she has taken to meet the challenges in teaching speaking with CLT.     

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。

融资约束视角下的碳信息披露与企业价值 ——基于文本分析的经验证据

随着中国双碳行动和绿色信贷政策的不断推进,碳信息披露作为外界评估企业环境风险和可持续发展能力的重要信息来源,已成为影响企业价值创造的重要因素。本文基于合法性理论和信号传递理论,以2015—2020年中国A股上市的高碳排放行业企业为研究样本,实证检验了碳信息披露的价值效应。研究发现：碳信息披露会抑制企业的短期价值,但可以促进企业长期价值的提升;进一步分析发现碳信息披露可以通过缓解企业融资约束来提升企业价值,但这种作用并非是立竿见影的。本研究揭示了企业的碳披露动机,深化理解了碳信息披露对企业价值的内在影响机理。此外,本文将文本分析和机器学习方法引入碳信息披露水平的研究,为该领域的研究方法提供了新的参考。
