The Effect on Enhancing Students＇ Inquiry Abilities via Step-by-Step Open-ended Inquiry Teaching Design     

Chung-Ming Yang  ;Jeng-Fung Hung  ;Tai-Chu Huang 《美中教育评论》2014,(12):887-894

The purpose of this study is to promote more open-ended inquiry activities in junior high school science lessons in the current educational system with fixed textbooks. Researchers adapted existing curriculum-based experimental activities for more open-ended inquiry ones. In addition, the whole class was provided with more opportunities to explore complete activities in limited teaching time. This study used Hazel＇s proposals of levels of inquiry. The method was to carry out the current 8th grade experiments through the step-by-step teaching material modification （from levels of inquiry 0 to 2b） and to combine the experimental teaching method with the 5E （engage, explore, explain, elaborate, and evaluate） learning cycle. After a quasi-experimental study, we compared the traditional teaching method with the step-by-step open-ended inquiry teaching one on 8th graders＇ basic and integrated science process skills and academic achievements. The study result showed that the academic achievement in the experimental group, based on the same instructional time, was not worse than that in the control group. No significant difference was found on the total scores of the basic science process skills between the two groups, but a significant difference was found on the ＂predicting＂ dimension. There was a significant difference on the total scores of the integrated science process skills between the two groups. Significant differences were found on ＂interpreting data＂ as well as ＂experiment designing＂ dimensions. Hence, the study indicated that it could enhance students＇ inquiry ability through step-by-step openly inquiry levels to change the existing curricula, which served as a reference of educational reform.  相似文献

中世纪英国货币流变与政治经济变迁初探     

崔洪健 《海南师范大学学报(社会科学版)》2014,(4):96-102

在罗马帝国的货币制度和欧洲大陆货币流变的影响下,中世纪早期(5-8世纪)英国的货币经历了对罗马帝国铜币的仿造→金币特里姆萨→银锡特→银便士的流变过程,最终选择铸造银便士。中世纪早期英国货币的流变不仅反映了当时政治经济变迁,而且也体现了货币在社会发展中的推动作用。  相似文献

中枢性运动疲劳相关神经递质5-HT的研究进展   总被引：7，自引：0，他引：7  

姚鸿恩  刘坤  荣湘江 《北京体育大学学报》2006,29(7):941-943

在初步阐明了5-HT导致中枢疲劳的机制之后,目前的中枢性运动疲劳的研究趋势主要是明确5-HT及5-HT受体在不同脑区的作用,5-HT受体拮抗剂与促进剂的作用.在此基础上更开展了很多通过营养或运动干预手段延缓与消除中枢疲劳的研究.随着神经生理学研究方法的改进,目前已经可以使用脑内微透析技术等方法进行活体动物神经递质的采样,达到动态检测运动中脑内神经递质变化的目的.国内使用新技术新方法研究中枢性运动疲劳还有待于进一步发展.  相似文献   

Cognitive development and instructional theory     

Charles J. Brainerd 《Contemporary educational psychology》1978,3(1):37-50

The foundations of the cognitive-developmental curriculum movement are briefly examined in this paper. The key features of this movement are the recommendations it makes in three areas: curriculum sequencing, curriculum content, and teaching strategies. Each of these areas is critically examined. It is concluded that the grounds for all proposals are purely theoretical. When the data are considered, they either contradict specific proposals or provide no direct evidence.  相似文献
