This study investigated changes in Korean science teachers' perceptions of creativity and science teaching after participating in an overseas professional development program. Participants were 35 secondary science teachers. Data were collected from open-ended questionnaires and interviews. Results indicated that participants showed a growing awareness that creativity can be expressed by every student; creativity can be enhanced; science has a much wider range of activities that foster creativity; and creativity-centered science teaching can be implemented in Korea. The major elements of the professional program that promoted these perceptual changes included hands-on creativity activities, observation of creativity-centered classrooms, and discussion with other teachers. Follow-up study revealed that their perceptual changes have been reflected in their teaching practices.  相似文献   

Translating Laboratory Evidence into Classroom Practice with Teacher‐Led Randomized Controlled Trials—A Perspective and Meta‐Analysis     

Richard Churches  Eleanor J. Dommett  Ian M. Devonshire  Robin Hall  Steve Higgins  Astrid Korin 《Mind, Brain, and Education》2020,14(3):292-302

We initiated and structured a single program that supervised teachers, some with neuroscience or psychology degrees, to collaborate and explore the effects of science of learning‐translated pedagogy. This article reports on the 34 findings from teacher‐led randomized controlled trials (RCTs) and replications. Teachers designed trials, looking at areas such as attention, memory, and spaced learning. Overall, positive effects were found over short periods (1–6 weeks; r = 0.15, p < .0001 [d = 0.30], N = 2,157). However, retrieval practice (testing as a learning experience) had differential effects mediated by age, approach, and lesson content. Results suggest science of learning‐translated pedagogy needs extensive replication to establish how best to use laboratory evidence in classrooms. Multiple planned replication of teacher‐led RCTs has potential as an evaluation tool, combining high levels of mundane realism with strong internal validity and the potential to build cost effective large samples for meta‐analysis.  相似文献

A method for sequencing instructional objectives which minimizes memory load     

John C. Nesbit  Steve Hunka 《Instructional Science》1987,16(2):137-150

A Gagné-style learning hierarchy often permits a large number of alternate linear arrangements (sequences) of instructional objectives. An alternative is described here to traditional methods of choosing between sequences. Its premise is that, for every sequence, a value temed thememory load can be calculated which is theoretically related to the probability that students will fail to recall prerequisite objectives. A graph theoretic approach is taken in presenting an algorithm which generates a minimal memory load sequence from a learning tree, a restricted but frequently encountered type of learning hierarchy. In order to assess the effectiveness of the algorithm in generating low memory load sequences when given hierarchies which are not trees, it was applied to several published examples of learning hierarchies. The results indicated that the algorithm is effective as an heuristic, especially when combined with a hill-descending procedure which attempts to incrementally improve the generated sequence.  相似文献   

Memory codes for temporal and nontemporal samples in many-to-one matching by pigeons     

Angelo Santi  Steve Bridson  Mary Jo Ducharme 《Learning & behavior》1993,21(2):120-130

Pigeons were trained to match temporal (2 and 8 sec of keylight) and color (red and green) samples to vertical and horizontal comparison stimuli. In Experiment 1, samples that were associated with the same correct comparison stimulus displayed similar retention functions; and there was no significant choose-short effect following temporal samples. This finding was replicated in Phase 1 of Experiment 2 for birds maintained on the many-to-one mapping, and it was also obtained in birds that had been switched to a one-to-one mapping by changing the comparison stimuli following color samples. However, in Phase 2 of Experiment 2, when the one-to-one mapping was produced by changing the comparison stimuli following temporal samples, a significant choose-short effect was observed. In Experiment 3, intratrial interference tests gave evidence of temporal summation effects when either temporal presamples or color presamples preceded temporal targets. This occurred even though these interference tests followed delay tests that failed to reveal significant choose-short effects. The absence of significant choose-short effects in Experiment 1 and in Phase 1 of Experiment 2 indicates that temporal samples are not retrospectively and analogically coded when temporal and nontemporal samples are mapped onto the same set of comparisons The interference test results suggest that the temporal summation effect arises from nonmemorial properties of the timing system and is independent of the memory code being used  相似文献   

Silent versus oral reading comprehension and efficiency     

R. Steve McCallum  Shannon Sharp  Sherry Mee Bell  Thomas George 《Psychology in the schools》2004,41(2):241-246

Seventy‐four students read passages from an individually administered test of reading comprehension (a subtest from the Test of Dyslexia, a test of reading and related abilities currently in development; McCallum & Bell, 2001), and then answered literal and inferential questions. Students were randomly assigned to one of two conditions; 39 students read the passages silently and 35 read orally, with time recorded for each passage read. Comprehension and time were dependent measures for a Multivariate Analysis of Covariance (MANCOVA) and two follow‐up Analyses of Covariance (ANCOVA). After controlling for reading ability, results from the MANCOVA showed a significant combined effect ( p < .05); however, a comparison of mean reading comprehension scores showed no significant difference between silent readers and oral readers ( p > .05). On the other hand, with reading ability controlled, silent readers took significantly less time to complete passages compared to those who read orally ( p < .02). In fact, students took 30% longer to read orally than silently, on average. When test directions do not specify either oral or silent reading and error analysis is not a goal, testing will be more efficient via silent responding with no loss of comprehension. © 2004 Wiley Periodicals, Inc.

How School Choice Is Framed by Parental Preferences and Family Characteristics: A Study of Western Area,Sierra Leone     

Pauline Dixon  Steve Humble 《Journal of School Choice》2017,11(1):95-110

This research set out to investigate how, in a post-conflict area, parental preferences and household characteristics affect school choice for their children. A multinomial logit is used to model the relationship between education preferences and the selection of schools for 954 households in Freetown and neighboring districts, Western Area, Sierra Leone. The increased economic well-being of a family tends to increase the likelihood of choosing a nongovernment school. As a child gets older parents are more likely to select government over nongovernment schools. For girls, parents are twice as likely to select a nongovernmental organization (NGO) school than a government one. Where parental preference for girls is a “safe environment” government is the preferred choice over a private proprietor school. Interestingly, the level of household education does not affect the likelihood of attending any school management type.  相似文献

Common core writing and language standards and aligned state assessments: a national survey of teacher beliefs and attitudes     

Gary A. Troia  Steve Graham 《Reading and writing》2016,29(9):1719-1743

A random sample of 482 teachers in grades 3 through 8 from across the United States were surveyed about (a) their perceptions of the version of the Common Core writing and language standards adopted by their state and their state’s writing assessment, (b) their preparation to teach writing, and (c) their self-efficacy beliefs for teaching writing. Regardless of grade, a majority of teachers believed that the adopted standards are more rigorous than prior standards, provide clear expectations for students that can be straightforwardly translated into activities and lessons, and have pushed them to address writing more often. However, many surveyed felt the new writing and language standards are too numerous to cover, omit key aspects of writing development, and may be inappropriate for struggling writers. Moreover, most did not feel that professional development efforts have been sufficient to achieve successful implementation, and nearly one in five respondents was not familiar with the standards. The respondents were generally less sanguine regarding their state’s writing test, with elementary teachers even less positive than middle school teachers on some aspects, though nearly a third were unfamiliar with their state test. A majority believed state writing tests, though more rigorous than prior tests, fail to address important aspects of writing development, do not accommodate the needs of students with diverse abilities, and require more time than is available to prepare students. Additionally, many teachers believed professional development efforts have been insufficient to help them understand measurement properties of the assessments and how to use test data to identify students’ writing needs. Teachers who were better prepared to teach writing and who held more positive personal teaching efficacy beliefs for writing exhibited generally more positive perceptions of their state’s standards. In contrast, only teacher efficacy beliefs made a unique contribution to the survey respondents’ attitudes and beliefs about their state’s writing test.  相似文献   

Providing school-based learning in elementary school mathematics: the case of a professional development school partnership     

Drew Polly 《Teacher Development》2017,21(5):668-686

Abstract

School–university partnerships also known as professional development school (PDS) partnerships provide potential for universities and schools to establish partnerships that can benefit university faculty, school teachers, university students, and school students. This study examines the impact of a PDS partnership in which the author served as a school-based mathematics coach for two years in a high-need elementary school. Data sources included interviews, surveys, and field notes from classroom observations. Inductive qualitative analyses which were situated in a multi-level framework for researching professional development found that teachers posed more cognitively demanding mathematical tasks and high-level questions in year two compared to year one of this project. Further, student achievement was noted on both state-wide and district-created assessments. Also teachers reported that the school-based approach to professional development led to some teachers taking on more informal leadership roles to support their colleagues’ mathematics instruction. Implications for school-based learning opportunities across the world include the need to establish specific university–school partnerships, and carefully designing research studies to examine the impact of these learning opportunities.  相似文献
