The research questions addressed in this study were: what types of epistemological beliefs do elementary students have; what types of metacognition do elementary students have; and what are the relationships among students’ perceived characteristics of constructivist learning environment, metacognition, and epistemological beliefs. A total of 626 students enrolled in sixth, seventh, and eight grades of nine elementary public schools located in Ankara, Turkey constituted the participants of this study. Constructivist learning environment survey (CLES), Junior metacognitive awareness inventory (Jr. MAI), and Schommer epistemological belief questionnaire (EB) were administered to students. Factor Analysis of Jr. MAI revealed both knowledge of cognition and regulation of cognition items were loaded into one factor. Confirmatory factor analysis of EB revealed a four factor structure namely innate ability, quick learning, omniscient authority, and certain knowledge. Regression analyses revealed that metacognition and omniscient authority were significant predictors of personal relevance dimension of CLES. Metacognition was found as the only predictor of the student negotiation. Innate ability and metacognition significantly contributed to uncertainty. This study revealed that the elementary students with different mastery levels hold different epistemological beliefs and multi-faceted nature of elementary school students’ metacognition was seemed to be supported with this study. It was found that metacognition contributed to model more than epistemological beliefs for all three dimensions of CLES.  相似文献   

Teaching Ecosystems and Matter Cycles with Creative Drama Activities     

Hulusi ?okadar  Gül?in Cihan Y?lmaz 《Journal of Science Education and Technology》2010,19(1):80-89

The purpose of this study is to examine the effect of creative drama-based instruction on seventh graders’ science achievements in the ecology and matter cycles unit and their attitudes toward science. The study is an experimental study carried out in one of the public elementary schools in Turkey during 2005–2006 schooling year. An ecological concept achievement test was developed and administered to 45 students in two classes (as control and experimental group) of an elementary school before and after the treatment. The experimental group received creative drama-based instruction and the control group received traditional instruction. A guiding instruction material which contains six lesson plans in the subject was constructed for the teacher to administer creative drama-based instruction. The topics of ecosystems and matter cycles were taught to the both of groups for 3 weeks. A science attitude test was administered to both groups before and after the treatment. The results revealed a statistically significant difference between the mean scores of the both groups with respect to achievement in the ecology concepts and median of the attitudes toward science in favour of the experimental group after the treatment.  相似文献

Developmental stability and changes in the impact of root consistency on children’s spelling     

S. Hélène Deacon  Sarah Dhooge 《Reading and writing》2010,23(9):1055-1069

The study reported here examined grade 2–4 children’s sensitivity to the consistency in the spelling of roots in related words. We build on earlier research by attempting to quantify the extent that children’s spellings of both inflected and derived forms accord with this principle. We contrasted children’s accuracy and consistency in spelling the root form (e.g., rock) with that of its spelling in related inflected and derived forms (e.g., rocks and rocky), as well as unrelated control forms (e.g., rocket). Across grades 2–4, children’s spellings accorded with the root consistency principle to the same extent for inflected and derived forms. Nevertheless, it was not until grade 4 that spellings maximally reflected the principle. These results are discussed in terms of how children’s spelling might come to reflect the root consistency principle that guides spelling in English.  相似文献   

Relations between impostor feelings and upward and downward identification and contrast among 10- to 12-year-old students     

Marie-Hélène Chayer  Thérèse Bouffard 《European Journal of Psychology of Education - EJPE》2010,25(1):125-140

The first objective of this study was to examine the presence of the impostor phenomenon (IP) among 740 students aged 10 to 12 years old. The second objective was twofold: (1) to examine the link between the impostor feelings and the propensity to use social comparison and (2) to examine whether this feeling is related to the processes of identification with versus contrast to others who are either doing better or worse than oneself. Results showed that, although generally of low intensity, the impostor feelings are indeed present in late elementary school children. A positive link between the impostor feelings and the propensity to use social comparison was also observed. It also appeared that, more than for others, children who feel like impostors were likely to differentiate themselves from their more capable peers while identifying themselves with less capable peers. The discussion focuses on the presence of the IP in late elementary children and on how the upward contrast and the downward identification may contribute to its development and maintenance.  相似文献   

Comparison of two methodological approaches for the mechanical analysis of single-joint isoinertial movement using a customised isokinetic dynamometer*

Compared to isokinetic and isometric tests, isoinertial movements have been poorly used to assess single-joint performance. Two calculation procedures were developed to estimate mechanical performance during single-joint isoinertial movements performed on a customised isokinetic dynamometer. The results were also compared to appreciate the effects of measurement systems and calculation procedures. Five participants performed maximal knee extensions at four levels of resistance (30, 50, 70 and 90% of the one-repetition maximum, 1-RM). Joint angular velocity and torque were assessed from customised isokinetic dynamometer measures (method A) and from weight stack kinematic (method B). Bland–Altman plots and mean percent differences (M_diff) were used to assess the level of agreement for mean and peak angular velocity and torque. A Passing–Bablok regression was performed to compare the angular velocity-angle and torque-angle relationships computed from the two analysis methods. The results showed a high level of agreement for all mechanical parameters (M_diff < 6% for all parameters). No statistically significant differences were observed between methods A and B in terms of angular velocity-angle and torque-angle relationships except at 30% of 1-RM for the torque-angle relationship. Both methodologies provide comparable values of angular velocity and torque, offering alternative approaches to assess neuromuscular function from single-joint isoinertial movements.  相似文献   

Mediating effects of motor performance,cardiorespiratory fitness,physical activity,and sedentary behaviour on the associations of adiposity and other cardiometabolic risk factors with academic achievement in children     

Eero A. Haapala  Niina Lintu  Aino-Maija Eloranta  Taisa Venäläinen  Anna-Maija Poikkeus  Timo Ahonen 《Journal of sports sciences》2018,36(20):2296-2303

We investigated the associations of cardiometabolic risk factors with academic achievement and whether motor performance, cardiorespiratory fitness, physical activity, or sedentary behaviour mediated these associations. Altogether 175 children 6–8 years-of-age participated in the study. We assessed body fat percentage (BF%), waist circumference, insulin, glucose, triglycerides, HDL cholesterol, and systolic and diastolic blood pressure, leptin, alanine aminotransferase, and gamma-glutamyltransferase (GGT). Reading fluency, reading comprehension, and arithmetic skills were assessed using standardized tests. Speed/agility, balance, and manual dexterity test results were used to calculate motor performance score and physical activity was assessed by combined heart rate and movement sensor and cardiorespiratory fitness by maximal cycle ergometer test. In boys, BF% was inversely associated with reading fluency (β = ?0.262, P = 0.007) and reading comprehension (β = ?0.216, P = 0.025). Motor performance mediated these associations. Leptin was inversely related to reading fluency (β = ?0.272, P = 0.006) and reading comprehension (β = ?0.287, P = 0.003). The inverse association of leptin with reading fluency was mediated by motor performance. In girls, GGT was inversely associated with reading fluency independent of confounders (β = ?0.325, P = 0.007). The inverse association of BF% with academic achievement among boys was largely explained by motor performance. Leptin in boys and GGT in girls were inversely associated with academic achievement independent of confounding factors.  相似文献   

Parents’ perceptions of parent–teacher relationship practices in Dutch primary schools – an exploratory pilot study     

Hélène Leenders  Carla Haelermans  Johan de Jong  Mélanie Monfrance 《Teachers and Teaching》2018,24(6):719-743

This paper shows how parents’ perceptions of parent–teacher relationship practices differ between different types of schools with respect to children’s special needs and the socio-economic status of these children. Using a questionnaire, we compare parents’ views from two special education schools, two at-risk schools serving low SES-children, and two mainstream primary education schools in the southern part of the Netherlands. The theoretical framework is based on Epstein’s Model of Parental Involvement. The results illustrate that parents and teachers in special education and at-risk schools are very much accustomed to ‘two-way communication’, in contrast to mainstream schools, and that this is valued highly by these parents. Furthermore, teachers in special and at-risk schools are more familiar with interacting with parents, involve them more in decision-making and more often co-ordinate homework practice with parents.  相似文献   

An example of the use of dynamic mathematics software to create problem-solving environments that serve multiple purposes     

Erdem Çekmez  Buket Özüm Bülbül 《Interactive Learning Environments》2018,26(5):654-663

Problem-solving is regarded as a major component of mathematical performance, and well-designed problem-solving-based learning environments have the potential to assist students in developing a meaningful understanding of mathematical concepts and procedures. In this respect, given its various features, dynamic mathematics software has been regarded by mathematics educators as a promising tool for designing such environments. This study presents an example of the use of technology to create a dynamic learning environment through a discussion of the pedagogical value of a problem selected for an activity, followed by the implementation sequence of the problem-solving activity in the classroom. The students’ experiences during the implementation of the activity are also discussed; and finally, an additional version of the problem is recommended for use in the classroom.  相似文献   

The Role of Orthographic and Semantic Learning in Word Reading and Reading Comprehension     

Catherine Mimeau  Jessie Ricketts  S. Hélène Deacon 《Scientific Studies of Reading》2018,22(5):384-400

We tested the theoretically driven hypotheses that children’s orthographic and semantic learning are associated with their word reading and reading comprehension skills, even when orthographic and semantic knowledge are taken into account. A sample of 139 English-speaking Grade 3 children completed a learning task in which they read stories about new inventions. Then they were tested on their learning of the spelling and meaning of the inventions (i.e., orthographic and semantic learning, respectively). Word reading and reading comprehension were assessed with standardised tasks, and orthographic and semantic knowledge were assessed with choice tasks targeting the spelling and meaning of existing words. The results of our structural equation modeling indicated that orthographic learning predicted word reading directly and reading comprehension indirectly via word reading. We also found that semantic learning predicted reading comprehension directly. These findings support integration of the self-teaching hypothesis and the lexical quality hypothesis.  相似文献
