Previous research has found a wide range of predictors of student performance in introductory college chemistry. These predictors are associated with both the students' backgrounds and their high school learning experiences. The purpose of this research study was to examine the link between high school chemistry pedagogical experiences and performance in introductory college chemistry while accounting for individual educational and demographic differences. The researchers surveyed 1531 students enrolled in first‐semester introductory college chemistry courses for science and engineering majors at 12 different U.S. colleges and universities. Using multiple regression analysis, the researchers uncovered several interesting high school pedagogical experiences that appeared to be linked with varying levels of performance in college chemistry. Most notably, the researchers found that repeating chemistry labs for understanding was associated with higher student grades, whereas overemphasis on lab procedure in high school chemistry was associated with lower grades in college. These results suggest that high school teachers' pedagogical choices may have a link to future student performance. © 2005 Wiley Periodicals, Inc. J Res Sci Teach 42: 987–1012, 2005  相似文献

What Makes a Student Group Successful? Student-Student and Student-Teacher Interaction in a Problem-Based Learning Environment   总被引：1，自引：0，他引：1

This study investigated student-student and teacher-student interaction in a problem-based course and looked at study success in relation to group dynamics and approaches to studying. Data for this study were provided by 31 law students who were enrolled in a course in legal history at the University of Helsinki in February 2001. The students were divided into three small groups that were tutored by one teacher. Both the students and the teacher were interviewed. The interaction between the students and their teacher, and the group dynamics of each subgroup, were observed during the tutor sessions. The results showed that the student groups were very different from each other in terms of study success, group dynamics and communication between the group members. One group achieved significantly higher grades than the other two groups. There was only one clear difference between the three groups. The interviews and observations showed that the students in the best group participated more evenly and actively in the discussions than students in the other two groups.  相似文献   

An idealistic view of teaching: teacher students’ personal practical theories     

Katriina Maaranen  Harri Pitkäniemi  Katariina Stenberg  Liisa Karlsson 《师资教育杂志》2016,42(1):80-92

Personal practical theories (PPTs) are built based on underlying beliefs, experiences, values and conceptions regarding ‘good teaching’. Having a vision of teaching and valuing the work may have a strong effect on one’s sense of identity, resilience and commitment. This study focused on Finnish teacher students’ (N = 84) PPTs constructed during the middle or at the end of their studies, on average during their fourth year of a five-year MA programme. All of the PPTs, written as statements (N = 647), were combined, and a unified conception of the theories was formed using inductive content analysis. The three main categories found were the foundations of good teaching, the teacher and the teacher’s daily work. The analysis of the statements shows that the notions of good teaching are very idealistic: they emphasise abstract ideologies and high standards for the teacher, but also everyday matters of teaching, although also here the ideology of the pupil’s individuality is at the centre. The paper concludes by arguing that it is good to have high aims and values for teaching, although in reality some of them might be difficult to achieve.  相似文献   

The development of children at familial risk for dyslexia: Birth to early school age     

Lyytinen H  Aro M  Eklund K  Erskine J  Guttorm T  Laakso ML  Leppänen PH  Lyytinen P  Poikkeus AM  Torppa M 《Annals of dyslexia》2004,54(2):184-220

Children at risk for familial dyslexia (n = 107) and their controls (n = 93) have been followed from birth to school entry in the Jyvaskyla Longitudinal study of Dyslexia (JLD) on developmental factors linked to reading and dyslexia. At the point of school entry, the majority of the at-risk children displayed decoding ability that fell at least 1 SD below the mean of the control group. Measures of speech processing were the earliest indices to show both group differences in infancy and also significant predictive associations with reading acquisition. A number of measures of language, including phonological and morphological skill collected repeatedly from age three, revealed group differences and predictive correlations. Both the group differences and the predictive associations to later language and reading ability strengthened as a function of increasing age. The predictions, however, tend to be stronger and the spectrum of significant correlations wider in the at-risk group. These results are crucial to early identification and intervention of dyslexia in at-risk children.  相似文献   

The literature of educational psychology and the literature used by writers in educational psychology     

F. W. Lancaster  K. Konopasek  Tina Owens 《Contemporary educational psychology》1985,10(4):314-328

Using Psychological Abstracts as the source of the original sample (“first-level”), various characteristics of the literature of educational psychology are compared with the characteristics of a “second-level” literature (defined as the literature that the first level cites). In particular, the scatter (dispersion) of periodical articles over periodical titles is looked at for both levels. The journals most cited within the literature of educational psychology are identified.  相似文献   

Stylistic Variation at the "Single-Word" Stage: Relations between Maternal Speech Characteristics and Children's Vocabulary Composition and Usage     

Julian M. Pine  Elena V. M. Lieven  Caroline F. Rowland 《Child development》1997,68(5):807-819

In this study we test a number of different claims about the nature of stylistic variation at the "single-word" stage by examining the relation between variation in early vocabulary composition, variation in early language use, and variation in the structural and functional propreties of mothers' child-directed speech. Maternal-report and observational data were collected for 26 children at 10, 50, and 100 words, These were then correlated with a variety of different measures of maternal speech at 10 words, The results show substantial variation in the percentage of common nouns and unanalyzed phrases in children's vocabularies, and singficant relations between this variation and the way in which language is used by the child. They also reveal singficant relations between the way in whch mothers use language at 10 words and the way in chich their children use language at 50 words and between certain formal properties of mothers speech at 10 words and the percentage of common nouns and unanalyzed phrases in children's early vocabularies, However, most of these relations desappear when an attempt is made to control for ossible effects of the child on the mother at Time 1. The exception is a singficant negative correlation between mothers tendency to produce speech that illustrates word boundaries and the percentage of unanalyzed phrases at 50 and 100 words. This suggests that mothers whose sprech provides the child with information about where new words begin and end tend to have children with few unanalyzed. phrases in their early vocabularies.  相似文献   

Self-esteem as a predictor of future school achievement     

Liisa Keltikangas-Järvinen 《European Journal of Psychology of Education - EJPE》1992,7(2):123-130

Self-esteem as a predictor of future school achievement was studied in 1253 randomly selected adolescents. Self-esteem was assessed with the Coopersmith’s Self-Esteem questionnaire when the students started a Junior or Senior High School. School achievement was measured when they graduated. Self-esteem appeared to be a valid predictor of the future grade average. From the components of self-esteem, general self-esteem and home-parents predicted the future performance while social self correlated slightly negatively with school achievement. A gender based difference was found: in boys the role of self-esteem was similar in all school stages while in girls the self-esteem was more significant in a comprehensive (i.e. compulsory) school and its role decreased in the later, voluntary schooling.  相似文献

Specific intellectual deficits in children with early onset diabetes mellitus   总被引：2，自引：0，他引：2  

J F Rovet  R M Ehrlich  M Hoppe 《Child development》1988,59(1):226-234

27 children with early onset (less than 4 years) diabetes (EOD), 24 with late onset (greater than 4.0 years) diabetes (LOD), and 30 sibling controls were compared in their performance on tests of intellectual functioning and school achievement. The results indicated that children with EOD, particularly girls, scored lower than the other groups of diabetic children and siblings on tests of visuospatial but not verbal ability. Many of the children with EOD were also having difficulty at school, and a number were currently receiving special education. Diabetic children with earlier onset had more hypoglycemic convulsions than those with later onset. Regression analyses revealed that duration of illness, age of onset, and hypoglycemic convulsions significantly predicted spatial ability.  相似文献
