Mathematical Flexibility: Aspects of a Continuum and the Role of Prior Knowledge     

Kristie J. Newton  Karin Lange  Julie L. Booth 《Journal of Experimental Education》2020,88(4):503-515

Abstract

Psychologists and mathematics educators have long viewed flexibility as critical to students’ mathematical development. In this paper, we focused on the multidimensional nature of flexibility to better understand how preference, knowledge, and use of effective methods for solving algebra problems are related. In Study 1, we identified research-based aspects of flexibility with algebra and assessed students on them following a two-step equations unit. Results indicated that certain aspects of flexibility develop prior to others and that prior knowledge of algebra plays a significant role in that development. Study 2 confirmed and elaborated on these results using a larger sample size. Implications for theory and for supporting flexibility in classrooms are discussed.  相似文献   

The relation between individual interest and knowledge acquisition          下载免费PDF全文

Jerome I. Rotgans  Henk G. Schmidt 《British Educational Research Journal》2017,43(2):350-371

The objective of this study was to examine how individual interest and knowledge acquisition are causally related. Three hypotheses were tested using a cross‐lagged panel analysis (N = 186) and two quasi‐experimental studies (N = 68 and N = 108) involving students from schools in Singapore. The first hypothesis is the broadly shared standard assumption on the relation between individual interest and knowledge: the more an individual is interested in a topic, the more (s)he is willing to engage in learning. An alternative hypothesis assumes that individual interest is not the cause but the consequence of the process of learning: individual interest as an affective by‐product of learning. Finally, a third possibility is that interest and knowledge influence each other reciprocally. The results supported the affective‐by‐product hypothesis. Our findings seem at variance with commonly held conceptions that being interested guides knowledge attainment. The implications of these findings for interest research are discussed.  相似文献   

历史话语参照下的自由言说--品读《花腔》     

任联齐 《宁波职业技术学院学报》2005,9(6):74-76

从语言表层来看，李洱的小说《花腔》模仿了历史话语的叙事方式，但其真正意图恰恰在于颠覆历史话语；作者通过惟妙惟肖地编造一个政治寓言，用个人的方式对个人与历史、知识分子与革命力量、人性与理性等重大命题进行形而上的思考，揭示了知识分子在独特的革命历史中的独特命运。  相似文献

汉末魏晋诗歌中浓郁的生命忧患意识     

李延江 《石家庄学院学报》2004,6(1):47-50

从先秦到汉末魏晋,诗歌在主题上发生了很大的变化,个体生命忧患意识逐渐成为诗歌的普遍主体。对个体生命的关注,对生死存亡的重视、感伤,对人生短促的感慨、喟叹,成为整个时代的典型音调。上至皇家贵族,下至中下层普通知识分子,都染上了这种时代的色彩,在其诗作中流露出浓重的人生悲凉感。  相似文献

郝云峰 《海南师范大学学报(社会科学版)》2004,17(6):123-124

随着经济的发展和人民生活水平的不断提高，如何选择风险小、收益高的投资品种使自己的个人财富得以保值增值，已成为我国居民十分关心的问题。股票市场、债券市场、保险市场、期货市场和外汇市场的形成为居民投资提供了多种选择，同时也使其风险控制成为日益突出的问题。金融投资风险管理的关键不是寻求完全避免风险，而是科学地评估风险，有效地应对风险，进而达到投资风险和投资收益的最优化配置。  相似文献   

对当前"七月派"研究中的若干基础界定的商兑     

王再兴 《黄冈师范学院学报》2006,26(4):89-93

目前七月派的研究中,还有许多基础性的界定问题存在着较大的模糊和分歧,这直接影响了七月派研究的深入与突破。笔者主张:七月派的流派存在时间不应为1937年到1949年的“十二年”,而应该认定为约半个世纪较为合适;以七月派刊物为代表的七月派的政治格调,也并非等同于单纯政治上的宣传或者文学上的主观主义,它实质上是七月派成员真诚的生活态度和艺术态度的自然展现;此外,七月派成员的判定,也应该采取相对宽松的尺度,如对待艾青等可以采取重叠的态度,对于舒芜,则应尽可能尊重历史的真实予以确认。  相似文献

Adapting mentoring to individual differences in novice teacher learning: the mentor’s viewpoint     

Gisbert van Ginkel  Helma Oolbekkink  Paulien C. Meijer  Nico Verloop 《Teachers and Teaching》2016,22(2):198-218

Being adaptive to the individual novice teacher is considered a condition for effective teacher mentoring. The aims of this study are therefore to explore (1) mentoring activities through which mentors intend to adapt to the individual novice teacher and (2) characteristics of adaptive mentors. Information was collected through on-site, post-mentoring conversation interviews with 18 mentors holding different mentoring conceptions, from different programs for Initial Teacher Education in the Netherlands. Four adaptive mentoring activities were identified: (1) aligning mutual expectations about the mentoring process, (2) attuning to the novices’ emotional state, (3) adapting the mentoring conversation to match the reflective capacity of the novice teacher, and (4) building tasks from simple to complex relative to the novices’ competence level. Adaptive mentors were (1) more likely to mention activities intended to support construction of personal practical knowledge and (2) less likely to mention activities intended to create a favourable context for novice teacher learning. Suggestions for using findings to enhance mentor adaptiveness are discussed.  相似文献
