数学学习的主要困难来自数学的高度抽象性,高职高专院校学生对数学望而生畏,教师在日常的教学中可利用数学应用的广泛性、数学自身的魅力、数学发展的历史或数学故事、数学悬念等各种方法去激发他们学习数学的热情.  相似文献   

Development in early literacy skills during the pre-kindergarten year in Head Start: Relations between growth in children's writing and understanding of letters     

Karen E. Diamond  Hope K. GerdeDouglas R. Powell 《Early childhood research quarterly》2008

Children's literacy skills are an important predictor of success in the early elementary grades. Education programs for at-risk preschool students target children's acquisition of specific literacy skills, including knowledge of letters of the alphabet, in preparing children for early school success. Writing has been proposed as a complementary approach to other instructional strategies for teaching young children about letters. This study examines relations among preschool children's early writing competence, knowledge of letter names, sensitivity to initial sounds in words and understanding of print concepts in a sample of low-income children enrolled in Head Start. Data were collected from the beginning to the end of the school year, which offered the opportunity to examine concurrent development of these early literacy skills. Results revealed that children whose writing was more sophisticated knew the names of more letters, understood more about print concepts and were more sensitive to initial sounds of words. There was evidence of bidirectional influences of writing on growth in letter knowledge, and of letter knowledge on growth in writing competence.  相似文献   

e-Voting intent: A comparison of young and elderly voters     

Anne Powell  Clay K. Williams  Douglas B. Bock  Thomas Doellman  Jason Allen 《Government Information Quarterly》2012

The ability to vote online has the potential to increase voter turnout for elections due to increased convenience over traditional voting polls. This study examines factors that can affect a citizen's intent to vote online. Survey subjects came from two different age groups: young adults, 18–25 years of age; and senior citizens, ages 60 plus. Using the Unified Theory of Acceptance and Use of Technology (UTAUT), the study found that performance expectancy, effort expectancy, social influence, trust in the internet, and computer anxiety were significantly related to intent to use online voting. Trust in the government was insignificant. Performance expectancy, social influence, and computer anxiety were related to intent to vote online for both young adults and seniors. Effort expectancy was related to intent to vote for the seniors but not young adults, and trust in the internet was related to intent to vote for young adults but not seniors.  相似文献   

Classroom contextual effects of race on children's peer nominations     

Jackson MF  Barth JM  Powell N  Lochman JE 《Child development》2006,77(5):1325-1337

Black children generally receive poorer sociometric nominations compared with Whites. This effect is not fully understood because Black children rarely hold a classroom majority and teachers' race is rarely investigated. Research from a person-environment perspective suggests that the effects of children's race depend on the racial composition of the classroom and society's racial attitudes. Sociometric nominations were obtained from 1,268 5th graders, between 9 and 11 years old (53% Black), across 57 classrooms (3-95% Black students). Half of the teachers were Black. The results indicated that ratings of Black children were more influenced by the racial context of classrooms than were ratings of White children. The implications of this study are discussed in relation to group dynamics and racial discrimination.  相似文献   

The effects of computer-assisted instruction on number combination skill in at-risk first graders     

Fuchs LS  Fuchs D  Hamlet CL  Powell SR  Capizzi AM  Seethaler PM 《Journal of learning disabilities》2006,39(5):467-475

The purpose of this pilot study was to assess the potential for computer-assisted instruction (CAI) to enhance number combination skill among children with concurrent risk for math disability and reading disability. A secondary purpose was to examine the effects of CAI on spelling. At-risk students were assigned randomly to math or spelling CAI, which they received in 50 sessions over 18 weeks. Acquisition and transfer effects were assessed. The results indicated that math CAI was effective in promoting addition but not subtraction number combination skill and that transfer to arithmetic story problems did not occur. Spelling CAI effects were reliable on acquisition and transfer spelling measures, with small to moderate effect sizes on transfer to reading measures. These results provide the basis for additional work with larger samples.  相似文献   

Exploring academic and cognitive skills impacting retention and acquisition of word-problem knowledge gained during or after intervention     

Xin Lin  Sarah R. Powell 《Child development》2023,94(6):e362-e376

In the present study, we investigated the impact of a word-problem intervention in retention and acquisition of knowledge after the intervention ended. We based analyses upon Grade 4 students experiencing mathematics difficulty (average age at pretest = 8.77) who received one of two variants of a word-problem intervention (with [n = 111] vs. without [n = 110] embedded pre-algebraic reasoning instruction) and students within a business-as-usual condition (BaU [n = 127]) separately. Findings revealed that students who received the intervention not only tended to retain less, but they also showed more active knowledge acquisition after the intervention ended. Furthermore, word-problem intervention altered the contributions of some prior knowledge and skills on both retention and acquisition.  相似文献
