关于认知方式的实验研究——场依存性特征对学习和图形后效的影响

本文报告了关于认知方式的两个实验研究。第一个实验通过镶嵌图形测验与少年儿童学习能力测验和课业成绩的比较,发现场独立性越强,数学能力越好,但与语文学习无关。第二个实验比较分析了在图形后效中附加参照物对于场依存性和场独立性的不同效应,发现附加参照物对于场依存性强的人的斜线图形后效有显著的影响,而对场独立性强的人影响不大。另外,本实验显示了在认知方式上存在着一定的性别差异。     

教学控制策略对小学儿童多媒体情境下英语学习效果的影响

该研究以103名二年级小学生为被试,运用教育实验方法探讨了在多媒体情境下,不同认知风格、英语水平的儿童在不同教学控制策略下的英语学习效果。结果发现:(1)英语水平较低的学生,无论其认知风格是场独立性还是场依存性,都是在教师控制策略下的学习效果好于教师指导下的学生控制策略;(2)英语水平较高且认知风格为场依存性的学生,在教师指导的学生控制策略下的学习效果显著好于在教师控制策略下的学习效果,而认知风格为场独立性的学生在两种策略下的学习效果没有显著差异。     

两种教学方法对不同认知风格11岁儿童数学学习效果的影响

比较运用尝试教学法教学和常规教学法教学对小学五年级独立型和场依存型的学生在解决三种难度的百分数应用题中的效果.结果发现:(1)从整体上看,在高难度题的测试中,以尝试教学法教学的成绩明显高于以常规教学法教学的成绩,两者的差异达到显著水平.对场依存的学生,在低难度题测试时,两种教学方法取得的成绩无显著差异;在中难度题测试时,以常规教学法教学的成绩高于以尝试教学法教学的成绩,差异达到显著水平;在高难度题测试时,以尝试教学法教学的成绩高于以常规教学法教学的成绩,两者的差异达到显著水平.对场独立的学生在低难度题测试时,两种教学方法取得的成绩无显著差异;在中、高难度题测试时,以尝试教学法教学的成绩均高于以常规教学法教学的成绩,差异达到显著水平.(2)从整体来看,在题为高难度时男生的成绩高于女生,差异达到显著水平,而在低、中难度时无显著的性别差异.场依存者在题为低难度时女生的成绩高于男生差异达到显著水平,而中、高难度时无显著的性别差异.场独立者在高难度时男生的成绩高于女生,差异达到显著水平.     

美术高考色彩教学探究

科学有效的教学设计对提高教学效率和培养学生的综合能力具有很大作用。学生在学习色彩时面临的最大困难就是难以同时兼顾造型和色彩塑造,所以教师在教学中不能光注重传授技法,而是要对教学程序进行合理的设计,运用多种教学手段,调动学生的积极性,将教学效果最优化。高效的色彩教学模式,有利于学生快速掌握色彩知识和技法,达到事半功倍的效果。     

认知特征、场独立性与飞行空间定向关系的研究

通过认知分化测验（ＣＬＢ）、团体镶嵌图形测验（ＧＥＦＴ）以及飞行定向水平的模糊评价技术,旨在检验认知特征、场独立性和飞行空间定向水平之间的关系。研究结果表明;（１）高水平的视觉空间认知能力及较强的场独立性特征不仅有助于获得一个良好的飞行定向水平,而且还构成了预测定向水平差异的有效指标;（２）场独立性特征与空间认知特征之间存在着一个很高的相关。具有较强场独立性特征的飞行员往往也具有较为典型的空间认知特征;（３）错觉水平较低的飞行员与中、重度错觉水平组飞行员在空间认知、认知分化和场独立性上的得分分别构成了显著的差异,表明轻度组飞行员在空间定向中表现出了良好的视觉空间信息组织、加工和某些元认知技能方面的优势。研究结果进一步证明了视觉空间认知加工和场独立性水平与飞行空间定向之间的紧密关系。     

高中生认知方式特点及其与学绩关系的研究

采用认知方式图形测验,对94名普通高中生进行实验研究,探讨了当前普通高中生认知方式特点及其与学绩的关系。结果表明：随着年级的增高,高中生的场独立性增强。高中生的认知方式场依存性、场独立性与学习成绩的相关不显著。在初中毕业刚进入高中,学生的认知方式存在显著的性别差异,但随着年级增长、个体成熟,这种差异逐渐缩小。文理分科对高中生的认知方式发展没有明显的影响。     

关于场依存性－独立性与催眠感受性及性格的比较研究

对场依存性独立性认知方式与催眠感受性及Ｙ—Ｇ性格测验所评定的人格特征的相互关系进行了研究,结果表明：场依存性－独立性与催眠感受性之间不存在相关关系,提示两者为彼此独立的人格特征;在人格特质方面．场依存性者比场独立性者具有更强的社会外向性、社交活动主导性和乐天性;而场独立性者则具有较强的神经质倾向;在人格类型上,场依存性者和场独立性者均普遍表现为Ａ、Ａ’和Ｄ型,而Ｃ型则更可能是场独立性者所具有的特征;从人格类型的研究角度证明,内、外向性格与场依存性－独立性基本上分属两个不同的人格维度;场依存性－独立性与个体心理健康水平无关。     

初中代数“有理数”程序教学实验研究

本研究对程序教学与传统教学的效果作了对比。研究表明,程序教学可以缩短学习时间、提高学习效果、激发学习动机,有助于自学能力的培养。如果程序教材能够符合学生的认识规律,在教材中尽量增加启发因素,那么程序教学对于思惟能力的培养也可以起到积极的作用。

提高色彩课教学效果应具备正确的教学方法与步骤。除此之外,教学所持的态度和观念因直接关系到色彩课的教学模式及产生的效果,应给予足够的重视。     

认知风格、内外向性、情绪稳定性与图形推理效果的关系

采用EFT、EPQ和RSPM-CR量表对156名理科大学生进行测量研究,结果发现：场独立性认知风格在图形系统变化、系列关系、抽象推理方面,较场依存性有明显优势;情绪稳定性高者图形推理的总体效果显著优于情绪稳定性低者;内向性者与外向性者的图形推理效果无显著差异;认知风格、情绪稳定性与图形推理总分有显著正相关,认知风格的正向预测力居首位。     

LEADERS IN READING RESEARCH AND INSTRUCTION

In this review, we examined the role of phonological awareness in literacy development for Spanish-speaking students. There appears to be a close relationship between Spanish-language phonological awareness and literacy development. In particular, Spanish phonological awareness appears to develop in stages. Not only is the development of phonemic awareness skills probably supported by reading instruction, but it likely contributes to reading development as well. Sensitivity to syllables in Spanish may be particularly important for later reading success, and the ability to segment words into their phonemes may play a critical role in reading acquisition. Training students in spelling, blending, and segmenting syllables and phonemes may be especially valuable because these skills are closely related to those which students use when actually reading and writing words. Finally, there is evidence of cross-language transfer of phonological awareness skills between Spanish and English. Suggestions for Spanish phonological awareness instruction are given, and an agenda for further research is included. Based on this review, many different experimental procedures have been used to evaluate students' Spanish-language phonological awareness, but there is a need for measures that are psychometrically sound and that have documented validity and reliability to assess phonological awareness in Spanish. In addition, although training in Spanish phonemic awareness seems to have a positive effect on the development of spelling ability, we found little direct evidence that this type of training increases Spanish reading performance. Further research in this area is needed.     

LEADERS IN READING RESEARCH AND INSTRUCTION

Recent research on negation has demonstrated that while readers are aware that this text construction is difficult, they seem to be able to do little to improve their comprehension. The present research evaluated whether a change in typeface could improve comprehension and metacomprehension of negation. Results indicated that while readers were aware that placing a word in bold typeface should attract their attention to that item, and therefore improve their comprehension, comprehension did not improve differentially for negation presented in bold. Additionally, readers' awareness of the necessity of attention to the bold component was not specific to negative sentences.     

LEADERS IN READING RESEARCH AND INSTRUCTION

Five reading lesson instruction characteristics were examined in relation to first and second graders' end-of-year instructional reading level: (a) teacher's preferred interaction style (indicated by extent of teacher telling and coaching); (b) teacher's preferred grouping (indicated by extent of whole class and small group instruction); (c) teacher's preferred focus of reading activity (indicated by extent of focus on words/letters and comprehension); (d) degree of student active response; and (e) instruction material (indicated by extent of use of narrative text and worksheets). Sixteen first- and second-grade teachers and 166 of their students were observed during reading instruction three times across the school year. Analyses of covariance were conducted. Complex relationships heretofore not revealed appeared. Different patterns of relationships between instructional characteristics and instructional reading level emerged for higher achievers compared to lower achievers and for first compared to second grade.     

STRATEGY INSTRUCTION FROM A SOCIOCOGNITIVE PERSPECTIVE

One of the characteristics of proficient readers and writers is their flexible use of reading and writing strategies. Students experiencing difficulties with reading and writing frequently do not use as many strategies as they read and write. Strategies are the cognitive tools that readers use as they construct meaning from text and that writers use as they produce texts. Many of the strategies that proficient readers and writers use are acquired and some are learned. Reading and writing strategies are frequently learned by purposeful instruction in meaningful social situations. This paper describes the nature of strategy use and instruction from a sociocognitive perspective, discusses the need for purposeful strategy instruction for struggling readers and writers, discusses factors that influence strategy instruction, describes current classroom practices that are congruent with sociocognitive theory, and suggests that strategy instruction should be grounded in classroom routines and situated within beliefs about teaching and learning.     

CONSTRUCTED-RESPONSE MATCHING TO SAMPLE AND SPELLING INSTRUCTION

The development of interactive programmed instruction using a microcomputer as a teaching machine is described. The program applied a constructed-response matching-to-sample procedure to computer-assisted spelling instruction and review. On each trial, subjects were presented with a sample stimulus and a choice pool consisting of 10 individual letters. In initial training, sample stimuli were arrays of letters, and subjects were taught to construct identical arrays by touching the matching letters in the choice pool. After generalized constructed-response identity matching was established, pictures (line drawings) of common objects were presented as samples. At first, correct spelling was prompted by also presenting the printed name to be “copied” via identity matching; then the prompts were faded out. The program was implemented with 2 mentally retarded individuals. Assessment trials determined appropriate words for training. Correct spelling was established via the prompt-fading procedure; training trials were interspersed among baseline trials that reviewed and maintained spelling of previously learned words. As new words were learned, they were added to a cumulative baseline to generate an individualized review and practice battery for each subject.     

论有关计算机辅助教学效果的研究

有关ＣＡＩ效果的研究经历了单纯的计算机教学功效研究、软件设计研究、ＣＡＩ应用过程研究和综合研究等四个方面。这些研究都是以计算机辅助教学与传统教学的效果对比为基础的,从大量的元分析研究看,对于ＣＡＩ是否比传统教学效果更好,人们的研究结果并不一致。之所以如此,不仅是因为影响ＣＡＩ效果的因素非常复杂,也是因为效果对比实验在研究思想和设计上都存在较大的漏洞,如对比实验在本质上并没有什么意义、研究设计不够完     

再探外显学习指导语的作用

本研究采用加工分离程序,对外显学习指导语的作用重新加以探讨.结果发现在外显学习指导语条件下,被试的作业成绩虽然较差,但并非由于外显指导语干扰了被试对规则的掌握.事实上,外显指导语促进了被试对规则的掌握.以往有关研究之所以出现不一致的结果,是由于它们采用任务分离范式,未能有效分离外显与内隐加工,以及记忆等因素的影响.
