A pre- and post-test quasi-experimental design was used to test the impact of a 30-week, theoretically-based social and emotional learning (SEL) curriculum, The RULER Feeling Words Curriculum (“RULER”), on the academic performance and social and emotional competence of 5th and 6th grade students (N = 273) in fifteen classrooms in three schools. Academic performance was assessed by report card grades. Social and emotional competence was assessed with teacher reports of student behavior. Students in classrooms integrating RULER had higher year-end grades and higher teacher ratings of social and emotional competence (e.g., leadership, social skills, and study skills) compared to students in the comparison group. This study provides preliminary empirical evidence that SEL programs like RULER improve important student outcomes. 相似文献

This study explored relations of print exposure, academic achievement, and reading habits among 100 deaf and 100 hearing college students. As in earlier studies, recognition tests for book titles and magazine titles were used as measures of print exposure, college entrance test scores were used as measures of academic achievement, and students provided self-reports of reading habits. Deaf students recognized fewer magazine titles and fewer book titles appropriate for reading levels from kindergarten through Grade 12 while reporting more weekly hours of reading. As in previous studies with hearing college students, the title recognition test proved a better predictor of deaf and hearing students' English achievement than how many hours they reported reading. The finding that the recognition tests were relatively more potent predictors of achievement for deaf students than hearing students may reflect the fact that deaf students often obtain less information through incidental learning and classroom presentations. 相似文献

Document clustering offers the potential of supporting users in interactive retrieval, especially when users have problems
in specifying their information need precisely. In this paper, we present a theoretic foundation for optimum document clustering.
Key idea is to base cluster analysis and evalutation on a set of queries, by defining documents as being similar if they are
relevant to the same queries. Three components are essential within our optimum clustering framework, OCF: (1) a set of queries,
(2) a probabilistic retrieval method, and (3) a document similarity metric. After introducing an appropriate validity measure,
we define optimum clustering with respect to the estimates of the relevance probability for the query-document pairs under
consideration. Moreover, we show that well-known clustering methods are implicitly based on the three components, but that
they use heuristic design decisions for some of them. We argue that with our framework more targeted research for developing
better document clustering methods becomes possible. Experimental results demonstrate the potential of our considerations. 相似文献

Spatial ability is an important factor in learning anatomy. Students with high scores on a mental rotation test (MRT) systematically score higher on anatomy examinations. This study aims to investigate if learning anatomy also oppositely improves the MRT‐score. Five hundred first year students of medicine (n = 242, intervention) and educational sciences (n = 258, control) participated in a pretest and posttest MRT, 1 month apart. During this month, the intervention group studied anatomy and the control group studied research methods for the social sciences. In the pretest, the intervention group scored 14.40 (SD: ± 3.37) and the control group 13.17 (SD: ± 3.36) on a scale of 20, which is a significant difference (t‐test, t = 4.07, df = 498, P < 0.001). Both groups show an improvement on the posttest compared to the pretest (paired samples t‐test, t = 12.21/14.71, df = 257/241, P < 0.001). The improvement in the intervention group is significantly higher (ANCOVA, F = 16.59, df = 1;497, P < 0.001). It is concluded that (1) medical students studying anatomy show greater improvement between two consecutive MRTs than educational science students; (2) medical students have a higher spatial ability than educational sciences students; and (3) if a MRT is repeated there seems to be a test effect. It is concluded that spatial ability may be trained by studying anatomy. The overarching message for anatomy teachers is that a good spatial ability is beneficial for learning anatomy and learning anatomy may be beneficial for students' spatial ability. This reciprocal advantage implies that challenging students on spatial aspects of anatomical knowledge could have a twofold effect on their learning.

Students’ Understanding of Conservation of Matter,Stoichiometry and Balancing Equations in Indonesia
This study examines Indonesian students’ understanding of conservation of matter, balancing of equations and stoichiometry. Eight hundred and sixty‐seven Grade 12 students from 22 schools across four different cities in two developed provinces in Indonesia participated in the study. Nineteen teachers also participated in order to validate the 25‐question survey used with all students. Significant differences in student success in answering specific questions occurred when comparing high‐achievement and low‐achievement schools. However, in general, student understanding of this fundamental principle in chemistry was low. The study found that the average score for all students on the survey was 41%. The findings suggest that students are most successful in solving problems used by teachers and textbooks that are algorithmic‐based (i.e., stoichiometry). As there were no strong positive correlations between student performance on conceptual questions and algorithmic questions, we suggest that further research should focus on teaching practices and curricula that support the development of the students’ conceptual understanding. 相似文献

This study explores biracial identity development in the adolescent years through fusion autoethnography. Using an ecological model of biracial identity development, this study illustrates how family, peers, and school curricula validate and reject racial self-presentations. We pay specific attention to the different forms of silence (i.e. “crickets”) that teachers and peers deploy as tactics of rejection and how racially coded artifacts such as hip-hop culture and Black Liberation texts function as validations of racial self-presentations. Overall, this study helps researchers and practitioners to understand the fluidity of biracial and multiracial identity development as it relates to everyday school spaces and processes. 相似文献

After nearly two decades of military dictatorship, democratic civic education has been integrated into the Ethiopian school curriculum. This paper examines the policy–practice concordance in implementing the civic education curriculum based on empirical evidence generated on the philosophical underpinnings, curricular contents, pedagogical approaches, and the role of instructional technology. Data were gathered through a questionnaire survey on 179 randomly selected high school students, key informant teachers, and content analysis of students’ textbooks, teachers’ guides, and official policy documents. The findings reveal that the existing civic and ethical education curriculum is eclectic in its character blending the minimal interpretation of democratic civic education with the inclusive conception of ethno-cultural diversity relevant to multicultural societies. Nevertheless, the manner in which the TV-instruction is used in classrooms is found to hinder interactive learning that is instrumental to nurture democratic and active citizens. 相似文献
