Adjusting speed to maintain fast and accurate performance is critical to goal-directed behavior. This study examined development of response time adjustments in the stop signal task in 13,709 individuals aged 6–17 years (49.0% Caucasian) across four trial types: correct and incorrect go, successful (stop-inhibit), and failed (stop-respond) trials. People sped more after correct than incorrect go responses and slowed more after failed than successful stop trials. Greater slowing after stop-respond but less slowing after stop-inhibit trials was associated with better response inhibition. Response time adjustments were evident in children as young as age 6, developed throughout childhood, and plateaued by age 10. Results were consistent with the predictions of the error detection and shifting goal priority hypotheses for adjustments.  相似文献   

Modelling quality     

Michael Christie  Hetty Grunefeld  Gerda Thibautt 《European Journal of Engineering Education》2001,26(4):441-450

This article argues that the increase in the number of teaching and learning centres in universities of technology in recent years is bound up with concerns about the quality of university education. Universities that have set up such centres have been motivated to do so for two main reasons. They are keen to improve the image and the capacity of their teaching faculty. They also hope to attract students at a time when many school leavers prefer immediate, well-paid employment to four or more years of study. There has been outside pressure as well. Governments have demanded that tertiary institutions become more accountable. Governments are insisting that taxpayers get value for their money, especially in the area of teaching and learning. The question asked in this article is whether or not teaching and learning centres should be modelling quality issues as well as teaching and learning issues. Our conclusion is that the centres should be proactive in this matter, providing their institution with both theoretical and practical models of quality management and assurance.  相似文献   

Designing Curriculum-Based Mathematics Professional Development for Kindergarten Teachers

This study examines the influence of a year-long mathematics professional development program on Kindergarten teachers’ beliefs, content knowledge, instructional practices, and their students’ achievement. The professional development program is grounded in the theoretical construct of learner-centered professional development and focuses on supporting teachers’ integration of standards-based pedagogies aligned with the Common Core State Standards in Mathematics. Data analysis included examining 15 Kindergarten teachers’ mathematics content knowledge, their beliefs about mathematics, their enactment of student-centered pedagogies, and student achievement on curriculum-based assessments. Findings indicated that teachers adopted more student-centered pedagogies and embraced more student-centered beliefs about mathematics teaching during their time in the project. Further, Kindergarten teachers also demonstrated gains in their mathematical content knowledge, and those content knowledge gains were linked to gains in student achievement.  相似文献

Getting in,getting on,going further: Exploring the role of employers in the degree apprentice to graduate transition     

Katy Jones  Fiona Christie  Sean Brophy 《British Educational Research Journal》2023,49(1):93-109

Transitions from education into work, or as part of career change and development, are increasingly central to policy debate and academic inquiry. However, the role that employers play in shaping transition is often overlooked. In this paper, we examine this issue through the experiences of a graduating cohort of ‘degree apprentices’. We present original analysis of new empirical data from what we believe to be the first substantive qualitative longitudinal research conducted with those experiencing this new vocational pathway in the English Apprenticeships system. Through analysis of repeat semi-structured interviews with 22 degree apprenticeship graduates (44 interviews in total), we provide early empirical insights into experiences of this new pathway and add to existing theoretical conceptualisations of transition within the educational literature and the employer's role within it. We show that the degree apprentice to graduate transition can be broken down into three key stages: ‘getting in’, ‘getting on’ and ‘going further’, and that employers—at both strategic and relational levels—shape experiences at each stage.  相似文献   

Instructional practices in secondary science: How teachers achieve local and standards-based success     

Beth A. Covitt  Elizabeth Xeng de los Santos  Qinyun Lin  Christie Morrison Thomas  Charles W. Anderson 《科学教学研究杂志》2024,61(1):170-202

This article reports on analyses of the instructional practices of six middle- and high-school science teachers in the United States who participated in a research-practice partnership that aims to support reform science education goals at scale. All six teachers were well qualified, experienced, and locally successful—respected by students, parents, colleagues, and administrators—but they differed in their success in supporting students' three-dimensional learning. Our goal is to understand how the teachers' instructional practices contributed to their similarities in achieving local success and to differences in enabling students' learning, and to consider the implications of these findings for research-practice partnerships. Data sources included classroom videos supplemented by interviews with teachers and focus students and examples of student work. We also compared students' learning gains by teacher using pre–post assessments that elicited three-dimensional performances. Analyses of classroom videos showed how all six teachers achieved local success—they led effectively managed classrooms, covered the curriculum by teaching almost all unit activities, and assessed students' work in fair and efficient ways. There were important differences, however, in how teachers engaged students in science practices. Teachers in classrooms where students achieved lower learning gains followed a pattern of practice we describe as activity-based teaching, in which students completed investigations and hands-on activities with few opportunities for sensemaking discussions or three-dimensional science performances. Teachers whose students achieved higher learning gains combined the social stability characteristic of local classroom success with more demanding instructional practices associated with scientific sensemaking and cognitive apprenticeship. We conclude with a discussion of implications for research-practice partnerships, highlighting how partnerships need to support all teachers in achieving both local and standards-based success.  相似文献

There’s a creepy guy on the other end at Google!: engaging middle school students in a drawing activity to elicit their mental models of Google     

Christie Kodama  Beth St. Jean  Mega Subramaniam  Natalie Greene Taylor 《Information Retrieval》2017,20(5):403-432

Although youth are increasingly going online to fulfill their needs for information, many youth struggle with information and digital literacy skills, such as the abilities to conduct a search and assess the credibility of online information. Ideally, these skills encompass an accurate and comprehensive understanding of the ways in which a system, such as a Web search engine, functions. In order to investigate youths’ conceptions of the Google search engine, a drawing activity was conducted with 26 HackHealth after-school program participants to elicit their mental models of Google. The findings revealed that many participants personified Google and emphasized anthropomorphic elements, computing equipment, and/or connections (such as cables, satellites and antennas) in their drawings. Far fewer participants focused their drawings on the actual Google interface or on computer code. Overall, their drawings suggest a limited understanding of Google and the ways in which it actually works. However, an understanding of youths’ conceptions of Google can enable educators to better tailor their digital literacy instruction efforts and can inform search engine developers and search engine interface designers in making the inner workings of the engine more transparent and their output more trustworthy to young users. With a better understanding of how Google works, young users will be better able to construct effective queries, assess search results, and ultimately find relevant and trustworthy information that will be of use to them.  相似文献   

Center Stage: Performing a Needs Assessment of Campus Research Centers and Institutes     

Andrea Malone  Lisa Martin  Christie Peters  Cherie Turner  Porcia Vaughn 《图书馆管理杂志》2017,57(4):406-419

Outreach to research centers and institutes is often overlooked in academic libraries. This article discusses a needs assessment conducted by the Liaison Services Department at the University of Houston Libraries that reviewed library services to centers and institutes at the University of Houston's main campus. The assessment was conducted for two purposes: to build collaborations with centers and to determine how the libraries might create new services and/or market existing services to meet the centers and institutes' growing research needs.  相似文献
