关于Ebbinghaus错觉机制的研究     

郭俊汝  韩玉昌  关尔群 《辽宁师范大学学报(社会科学版)》2005,28(6):53-57

Ebbinghaus错觉是指当一个物体被比它大的物体所环绕包围时,它看上去要比实际小,而当被比它小的物体所环绕包围时,它看上去要比实际大.从结构因素(生理)和策略(认知)因素两个方面研究回顾了对Ebbinghaus错觉机制的解释.认为单一的生理或认知的因素都不能充分解释Ebbinghaus 错觉的产生机制;Ebbinghaus错觉形成的机制是复杂的,对它的探索过程是一条漫长之路.  相似文献   

Video-assisted thoracoscopic surgery （VATS） for bilateral primary spontaneous pneumothorax   总被引：3，自引：0，他引：3

Objective:To review our experience of the treatment of bilateral primary spontaneous pneumothorax (PSP) by video-assisted thoracoscopic surgery (VATS). Materials and methods: Retrospective chart review was followed by an on-clinic or telephone interview. Patients were cared for by one thoracic surgeon in four medical centers or community hospitals in Northern and Central Taiwan. Thirteen patients with bilateral PSP underwent bilateral VATS simultaneously or sequentially from July 1994 to December 2005. Results: Twelve males and one female, with age ranging from 15 to 36 years (mean 23.1 years), were treated with VATS for bilateral PSP, under the indications of bilateral pneumothoracis simultaneously (n=4) or sequentially (n=9). The interval between the first and second contra-lateral VATS procedure for non-simultaneous PSP patients ranged from 7 d to 6 years. Eleven of 13 patients (84.6%) had prominent pulmonary bullae/blebs, and underwent bullae resection with mechanical or chemical pleurodesis. The mean operative time was (45.6±18.3) min (range 25-96 min) and (120.6±28.7) min (range 84-166 min) respectively for the non-simultaneous (second VATS for the recurrence of contralateral side after first VATS) and simultaneous (bilateral VATS in one operation) procedures. There was no postoperative mortality. However, prolonged air leakage (>7 d) occurred in one patient (7.7%) who recovered after conservative treatment. The mean duration of chest tube drainage was 3.1 d and the median follow up period was 3.4 years. Conclusions: VATS is a safe and effective procedure in the treatment of bilateral PSP. Bilateral VATS is only recommended for patients with simultaneously bilateral PSP, because the incidence of recurrence, even with visible bullae, was not so high in my group and in some previous literature. Bilateral VATS in a supine position should only be used in selective cases, because of possible pleural adhesion or hidden bullae on the posterior side.  相似文献   

Using a concept mapping strategy to improve the motivation of EFL students in Google Hangouts Peer-Tutoring Sessions with native speakers     

Ting-Chia Hsu 《Interactive Learning Environments》2019,27(2):272-285

This study examines four elements of learner motivation, attention, relevance, confidence, and satisfaction, in an EFL speaking course that uses the computer mediated communication (CMC) tool Google Hangouts. The study found that a preparatory concept mapping task before the CMC sessions improved students’ perceived attention, relevance, confidence, and satisfaction. However, follow-up reflective worksheets had no effect on perceived attention, relevance, confidence, or satisfaction. Instructors should use concept mapping in a pre-task to support learners engaged in CMC-based speaking activities with native and non-native speakers. When the students used concept mapping to prepare for the CMC-based speaking activities, they exhibited higher confidence in their oral practice activities with a native speaker.  相似文献   

Development and Validation of a Multimedia-based Assessment of Scientific Inquiry Abilities     

Che-Yu Kuo  Tsung-Hau Jen  Ying-Shao Hsu 《International Journal of Science Education》2013,35(14):2326-2357

The potential of computer-based assessments for capturing complex learning outcomes has been discussed; however, relatively little is understood about how to leverage such potential for summative and accountability purposes. The aim of this study is to develop and validate a multimedia-based assessment of scientific inquiry abilities (MASIA) to cover a more comprehensive construct of inquiry abilities and target secondary school students in different grades while this potential is leveraged. We implemented five steps derived from the construct modeling approach to design MASIA. During the implementation, multiple sources of evidence were collected in the steps of pilot testing and Rasch modeling to support the validity of MASIA. Particularly, through the participation of 1,066 8th and 11th graders, MASIA showed satisfactory psychometric properties to discriminate students with different levels of inquiry abilities in 101 items in 29 tasks when Rasch models were applied. Additionally, the Wright map indicated that MASIA offered accurate information about students’ inquiry abilities because of the comparability of the distributions of student abilities and item difficulties. The analysis results also suggested that MASIA offered precise measures of inquiry abilities when the components (questioning, experimenting, analyzing, and explaining) were regarded as a coherent construct. Finally, the increased mean difficulty thresholds of item responses along with three performance levels across all sub-abilities supported the alignment between our scoring rubrics and our inquiry framework. Together with other sources of validity in the pilot testing, the results offered evidence to support the validity of MASIA.  相似文献

运用文献资料、问卷调查和数据统计等研究方法,对牡丹江普通高校学生双休日闲暇体育现状进行调查。结果发现:多数学生能认识到闲暇体育重要性,但在实际实施过程中,未能落到实处,也没有找到自己终身坚持锻炼的项目。影响学生参加锻炼因素主要有场地器材不完善,学生对体育认识不足及时间和体育技能等因素。根据现状提出一些相应对策与建议。  相似文献   

Strategic fit among knowledge attributes,knowledge management systems,and service positioning     

Che-Hung?Lin  Fu-Sheng?TsaiEmail author  David D C?Tarn  Shu-Chuan?Hsu 《知识管理研究与实践》2015,13(3):272-280

Knowledge management systems (KMSs) support high-quality services while shaping and improving positioning of services. Given such strategic importance of KMS, this study explores the effects of different types of KMS, which respond to the attributes (i.e., diversity and tacitness) of collective knowledge, on service (re-)positioning. Through a case study of a financial consulting company at the core of KMSs, combinations of the two knowledge attributes are used to determine which type of KMS (i.e., information library, deepened stock, thought islands, and shared brain) offers the greatest efficiency and effectiveness in service (re-)positioning. The joint concerns of service innovation scope and specificity are also considered. Finally, the study discusses the theoretical and practical implications on KMS design and functionality in the new business age of service innovation.  相似文献
