This study explored Canadian and American pre-service elementary teachers’ self-efficacy beliefs for literacy instruction, as well as the contextual factors (i.e., course and field experiences) that contribute to these self-efficacy beliefs. Survey data were collected over a two-year period at the beginning and end of a required elementary literacy methods course that assessed pre-service teachers’ self-efficacy for literacy instruction. A content analysis of the American and Canadian literacy methods course syllabi was also conducted. Paired t test results showed no significant difference in pre-service teachers’ literacy teaching self-efficacy scores from pre-test to post-test; however, there was a significant difference in the pre-service teachers’ literacy efficacy beliefs related to oral reading from the beginning to the end of the course. A weak negative correlation was found between the Canadian pre-service teachers’ total Teachers’ Sense of Efficacy for Literacy Instruction (TSELI; Tschannen-Moran & Hoy, 2011) scores and their teaching experience specific to literacy instruction, r = ? .1, p = .04. There was a positive correlation between Canadian pre-service teachers’ self-efficacy scores related to engagement and differentiated instruction and their volunteer and work experiences. A positive correlation existed between Canadian and American pre-service teachers’ self-efficacy for reading/writing connections and university coursework related to literacy instruction. Implications for literacy teacher educators and recommendations for literacy instruction are discussed.  相似文献

Several concepts have been developed to implement research-oriented teaching in higher education in the last 15 years. The definition of research competences, however, has received minor attention so far. Some approaches to modeling research competences describe these competences along the research process but either focus on a specific academic discipline and/or specific facets or offer no empirical verification for cross-disciplinary approaches. We have developed a new approach to model research competences across various academic disciplines in form of a competence model—the RMRC-K-model. This model comprises five dimensions: skills in reviewing the state of research, methodological skills, skills in reflecting on research findings, communication skills, and content knowledge. In this study, we present an instrument (R-Comp) developed on the basis of this cross-disciplinary competence model. The factorial structure of the R-Comp was examined with data from 391 university students in three groups, either enrolled in a Bachelor’s degree, Master’s degree, or a PhD program. The sample represented various academic disciplines. Results from confirmatory factor analyses supported the hypothesized structure of the R-Comp for the five dimensions in accordance with the RMRC-K-model. Additionally, results provided evidence for a more detailed differentiation of all dimensions with sub-dimensions reflecting theorized facets of the model. Both Cronbach’s α and construct reliability H indicated overall good reliability. Despite limitations to this study, there is some first evidence of a valid and reliable assessment of student research competences.  相似文献

Formative Assessment (FA) refers to eliciting evidence about students’ understanding and using the information to support learning, e.?g. via individual feedback. There is evidence that FA fosters students’ motivation, but less is known about the underlying processes. The present study investigates direct effects of FA on intrinsic motivation as well as the mediating role of students’ perceived competence, drawing on Deci and Ryan’s self-determination theory. In a randomized, controlled trial, primary school teachers were either assigned to an FA training (n?=?17) or to a control group (CG; n?=?11). All teachers then taught two science units in their classrooms (FA: n?=?319 students, CG: n?=?232). Multilevel regression analyses showed a higher perceived competence and a marginally higher intrinsic motivation for FA students after unit 1. After unit 2, both intrinsic motivation and perceived competence were higher in the FA condition, and the impact on intrinsic motivation was significantly mediated by students’ perceived competence after the first unit. These results confirm and extend previous findings on the effectiveness of formative assessment on motivational outcomes.  相似文献

Children from low-income families are at greater risk for poor social–emotional development and physical health and may be in need of intervention. This study examined the extent to which the Positive Action (PA) preschool lessons improved low-income children’s social–emotional competence and health behaviors. Mixed findings emerged with regard to whether the lessons facilitated growth in child outcomes. Results showed positive effects of PA on children’s directly assessed social problem solving skills and their parent-rated social–emotional competence and health behaviors. Unexpectedly, program effects on teacher ratings of social–emotional competence were in the opposite direction. These findings provide preliminary evidence that PA may be effective in promoting positive social–emotional and health behavior outcomes for children, particularly when outcomes are assessed directly and by parents.  相似文献

This article aims to study the relationship between teachers’ judgment and pupils’ self-perceptions controlling for the big-fish-little-pond effect (BFLPE). Three studies were conducted among third-grade pupils. Study 1 (n?=?585) focused on pupils’ perceptions of their scholastic competence. Teachers’ judgment and BFLPE were found to have an independent relation with pupils’ self-perceived scholastic competence. Study 2 (n?=?660) replicated the same results of study 1. Study 3 (n?=?683) extended the analysis to other domains of self-perception identified by Harter (Child development, 53, 87–97, 1982). The results showed that the relation with the BFLPE was significant only for pupils’ self-perceived scholastic competence. They also showed that the teachers’ judgment was related to two other domains of self-perception (behavioral conduct and peer acceptance) but was not directly related to pupils’ global self-worth.  相似文献

Despite the prevalence and significance of e-learning in education, there is a dearth of published instruments for educational researchers and practitioners that measure users’ acceptance of e-learning. To meet this need, Teo (2010) developed the E-learning Acceptance Measure (ElAM). The main objective of this paper is to validate the ElAM (Teo, 2010) across two cultures, one is from a European country: England, and the other from Asia: Lebanon. A total sample of 461 university students from two private universities in Lebanon (n?=?209) and one university in England (n?=?252) participated in this study. Using confirmatory factor analyses, our findings revealed that the original 3-factor solution for ElAM (Teo, 2010) was supported and found to be adequate for the British sample, whereas the results revealed a bad fit for the Lebanese sample. Despite the differences, the ElAM was found to possess an acceptable level of internal consistency and item reliability for the pooled sample. Theoretical and practical implications are discussed at the end of the paper.  相似文献

This empirically driven paper is about workplace learning with specific focus on the ‘work’ of consuming practices. By consuming we refer to the eating, and the drinking, and (at times) to the smoking that workers, in most organisations, do on a daily basis. Indeed, it is the quotidian nature of consuming, coupled with its absence from workplace learning research that make them noteworthy practices to explore. In using the term practice we draw on the recent tranche of practice based theorisations: notably Schatzki (1996, Organization Studies, 26(3), 465-484, 2005, Organization Studies, 27(12), 1863-1873, 2006) and Gherardi (Human Relations, 54(1), 131-139, 2001, 2006, Learning Organization, 16(5), 352-359, 2009). The paper frames consuming practices as ‘dispersed’ (general) practices and, illustrated through empirical data from multiple projects, we progressively outline how these contribute to the learning of ‘integrative’ (specialized work) practices. Our overall aim is to (re)position consuming practices from prosaic, to having much relevance for research on workplace learning.  相似文献

This study proposes a model for describing the situation of Digital Teaching and Learning (TD-TaL) in Ghanaian schools using the perspectives of basic school teachers. The Digital Teaching and Learning model was developed based on the theories of Valsiner’s Zone of Free Movement (ZFM) and Zone of Promoted Action (ZPA) and Vygotsky’s Zone of Proximal Development (ZPD). The model proposes to look at the effects of ZFM in schools (comprising Digital environment factors and Personal attitudinal and Digital Culture factors) and ZPA (comprising Teacher Training factor) on the Teachers’ Digital Knowledge, Competence and Action ( TDKCA) factors to influence teachers in their Zone of Proximal Development. The model was tested in Ghana’s case using the survey data collected from 256 teachers from 45 schools across six districts in the Western Region of Ghana. The findings from Regression path analysis revealed that Personal and Digital Culture factors, but most of all teachers’ Digital Attitudes effected directly on Teachers’ Digital Activities they claimed to be doing, whereas from Environmental factors only Schools’ Digital Agenda was impacting Teachers’ Digital Action both directly and indirectly through Teachers’ Digital Training (ZPA). The model specifically highlighted that in observed Ghanaian schools the ZFM factors Digital Infrastructure and Digital Support to Digital Teaching did not associate with the ZPA factor Digital Teacher Training and overall to Teachers’ Digital Knowledge, Competence and Action factors.  相似文献

The term ‘high-dimensional’ refers to the case where the number of unknown parameters to be estimated, p, is of much larger order than the number of observations, n, that is p ? n. Since traditional statistical methods assume many observations and a few unknown variables, they can not cope up with the situations when p ? n. In this article, we study a statistical method, called the ‘Least Absolute Shrinkage and Selection Operator’ (LASSO), that has got much attention in solving high-dimensional problems. In particular, we consider the LASSO for high-dimensional linear regression models. We aim to provide an introduction of the LASSO method as a constrained quadratic programming problem, and we discuss the convex optimization based approach to solve the LASSO problem. We also illustrate applications of LASSO method using a simulated and a real data examples.  相似文献

This study reports relationships between general academic self-concept and achievement in grade 3 and grade 5. Gender-specific effects were investigated using a longitudinal, two-cycle, 3-year autoregressive cross-lagged panel design in a large, representative sample of Polish primary school pupils (N?=?4226). Analysis revealed (a) reciprocal relations between general academic self-concept and achievement over time but the influence of prior achievement on self-concept was stronger; (b) on average, levels of both constructs declined over time; (c) gender differences were not observed in longitudinal relations (i.e. cross-lagged, autoregressive and intra-wave correlations); (d) girls demonstrated higher mean levels of academic achievement at both grades; and (e) average level of general academic self-concept was not gender differentiated in grade 3 but decreased more for girls. These results are discussed in the light of the theoretical and practical implications.  相似文献

3D printing technology is a powerful educational tool that can promote integrative STEM education by connecting engineering, technology, and applications of science concepts. Yet, research on the integration of 3D printing technology in formal educational contexts is extremely limited. This study engaged preservice elementary teachers (N?=?42) in a 3D Printing Science Project that modeled a science experiment in the elementary classroom on why things float or sink using 3D printed boats. The goal was to explore how collaborative 3D printing inquiry-based learning experiences affected preservice teachers’ science teaching self-efficacy beliefs, anxiety toward teaching science, interest in science, perceived competence in K-3 technology and engineering science standards, and science content knowledge. The 3D printing project intervention significantly decreased participants’ science teaching anxiety and improved their science teaching efficacy, science interest, and perceived competence in K-3 technological and engineering design science standards. Moreover, an analysis of students’ project reflections and boat designs provided an insight into their collaborative 3D modeling design experiences. The study makes a contribution to the scarce body of knowledge on how teacher preparation programs can utilize 3D printing technology as a means of preparing prospective teachers to implement the recently adopted engineering and technology standards in K-12 science education.  相似文献

The relationship between 2nd and 3rd grade teachers’ linguistic knowledge and spelling instructional practices and their students’ spelling gains from fall to spring was examined. Second grade (N = 16) and 3rd grade (N = 16) teachers were administered an instructional practices survey and a linguistic knowledge test. Total scores on the two instruments were not significantly related (r = 0.20), indicating two different constructs. Students (N = 331 2nd graders, N = 305 3rd graders) completed a 40 item spelling dictation test in the fall and spring. HLM analyses were conducted on subsamples of weaker spellers (Ns = 226 2nd graders and 50 3rd graders) who spelled fewer than 20 words correctly on the pretest. Limiting the sample to weaker spellers eliminated ceiling effects on pre- to posttest gains. Results revealed that 2nd grade teachers’ linguistic knowledge of phonemic units in words, their teaching of spelling strategies, the time they spent in weekly spelling instruction, and the greater the number of weaker spellers in their classrooms, were significant predictors of weaker spellers’ improvement in spelling. For 3rd grade teachers, HLM analyses were not significant perhaps due to lack of power. However, 3rd grade teachers’ phonemic knowledge was significantly correlated with weaker spellers’ gain scores. Results while correlational provide tentative support for the conclusion that teachers who are more knowledgeable about phonemes in words and who utilize more effective, research based spelling instruction are more successful in teaching spelling to weaker spellers.  相似文献

Quantum theory’s unusual predictions stem from its basic formalism which involves concepts like the wavefunction or probabilityamplitudes instead of probabilities. Many serious doubts have been raised about quantum theory’s connection with perceived classical dynamics. How does quantum mechanics, with all its strange ideas, unfold to give us the ‘reality’ of the familiar physical world? What is the connection between theclassical and thequantum! If quantum mechanics is, indeed, the fundamental theory of nature, as is widely accepted, then how does it explainclassicality! In the following, some of the fascinating conceptual problems of quantum mechanics are highlighted. The ‘environment-induceddecoherence’ approach is then discussed as one practical attempt at explaining the emergence of a classical world from an underlying quantum substrate  相似文献

This paper reports on a mixed-methods case study investigating how higher education staff and students understand, experience and envision the ‘international university’. As it is becoming clear that international student mobility is not in itself a panacea for universities seeking to internationalise, ‘internationalisation at home’ and ‘global citizenship’ are increasingly permeating university policy documents and mission statements. However, little is known about how students and staff on the ground perceive and experience these concepts. Quantitative and qualitative data were collected at one British university through focus groups (N = 19) and through an online survey (n = 148). Findings revealed a conventional mobility-focused understanding of the international university among students and staff, and a great deal of cynicism as regards ‘internationalisation at home’ and ‘global citizenship’. We discuss implications for practice and a research agenda.  相似文献

This systematic review explores the impact of teacher professional development (PD) on student reading achievement. The first part of the literature evaluates all available existing systematic reviews and meta-analyses of PD intervention studies. No quality reviews of PD and reading specifically (distinct from ‘attainment’) were found. There was a little overlap of studies in existing reviews. The second part of the systematic review focuses on the most recent intervention studies exploring PD and student reading achievement. The results of a meta-analysis of all high-quality studies are presented in the third part of the paper. This analysis showed no strong evidence of publication bias and an effect size for PD on student literacy of g = 0.225. This effect was moderated by the number of hours of PD whereby studies with fewer than 30 h of PD was significant for student reading outcomes (g = 0.367, p < 0.001) but more than 30 PD hours was not significant (g = 0.143, p > .05). Following a Weight of Evidence assessment, analysis showed that nearly all high-quality articles involved shorter PD. Weight of Evidence was a significant moderator, (g = 0.408, p < 0.001 for high-quality studies, g = 0.077, p > 0.5, n.s., for medium quality studies). Our review suggests that only high-quality studies of short teacher PD currently provide evidence of impact on student’s reading achievement.  相似文献

This study refined the Multicultural Counseling Knowledge and Awareness Scale (MCKAS; Ponterotto et al. Journal of Multicultural Counseling and Development, 30, 153–180, 2002) in response to concerns in the literature (e.g., Constantine et al. Cultural Diversity and Ethnic Minority Psychology, 8(4), 334–345, 2002) focusing on original sample representation, factor structure, and constructs of interest within this scale. For this refinement study, a total of 176 participants from various counseling fields in the United States completed an online survey. The results of an exploratory factor analysis presented a 28-item 2-factor refined version of the MCKAS (MCKAS-R). The preliminary MANOVA analysis indicated that this refined scale differentiated multicultural counseling competencies of participants who were counselors, counseling students, and counselor educators. Implications of this scale for counselor training, practice, and future research are provided.  相似文献

Children as readers of picture books and the ways they respond to, and make meaning from, such texts are the focus of this article, which reports on a small-scale study undertaken in Norway and Wales, UK. The theoretical framing of the research draws on concepts of the multimodal ensemble in picture books and of the reading event as part of a social practice. The research design was developed from the team’s analysis of two texts, Pappa by Svein Nyhus (1998) and What does Daddy Do? by Rachel Bright (2009). Twenty-four children, who were 7 and 8 years old, took part in the study. This was built around two reading events for each book, staged as an immediate response and as a guided response. The data subsequently collected were analysed according to three overarching organisational principles, as book world, real world and play world. For both Daddy and Pappa, the first reading event showed the children’s responses were mainly directed towards exploring the book world. On the second reading event, references to the real world predominated for Daddy, while for Pappa the book world was again dominant. Across both reading events and for both books, the playworld revealed those occasions when the children expanded the meaning of the story, demonstrating an inventive ability to play with the text. Overall, the children’s responses moved fluidly across the three worlds, showing them to be energetically making connections between the reading, their experience of books and their own lives.  相似文献

Background

Coronary heart disease (CHD) is characterized by arterial wall inflammation and matrix degradation. Matrix metalloproteinase (MMP)-22 and -29 and pro-inflammatory cytokine interleukin-18 (IL18) are present in human hearts. IL18 may regulate MMP-22 and -29 expression, which may correlate with CHD progression.

Methods and results

Immunoblot analysis showed that IL18 induced MMP-22 expression in human aortic smooth muscle cells. The Mann Whitney test from a prospective study of 194 CHD patients and 68 non-CHD controls demonstrated higher plasma levels of IL18, MMP-22 and -29 in CHD patients than in the controls. A logistic regression test suggested that plasma IL18 (odds ratio (OR)=1.131, P=0.007), MMP-22 (OR=1.213, P=0.040), and MMP-29 (OR=1.198, P=0.033) were independent risk factors of CHD. Pearson’s correlation test showed that IL18 (coefficient (r)=0.214, P=0.045; r=0.246, P=0.031) and MMP-22 (r=0.273, P=0.006; r=0.286, P=0.012) were associated with the Gensini score before and after adjusting for potential confounding factors. The multivariate Pearson’s correlation test showed that plasma MMP-22 levels correlated positively with high-sensitive-C-reactive protein (hs-CRP) (r=0.167, P=0.023), and MMP-29 levels correlated negatively with triglyceride (r=?0.169, P=0.018). Spearman’s correlation test indicated that plasma IL18 levels associated positively with plasma MMP-22 (r=0.845, P<0.001) and MMP-29 (r=0.548, P<0.001).

Conclusions

Our observations suggest that IL18, MMP-22 and -29 serve as biomarkers and independent risk factors of CHD. Increased systemic IL18 in CHD patients may contribute to elevated plasma MMP-22 and -29 levels in these patients.
