This longitudinal study examined the influence of prekindergarten teacher characteristics and classroom instructional processes during mathematical activities on the growth of mathematics learning scores in prekindergarten, kindergarten, and first grade. Participants attended state-funded and Head Start prekindergarten programs. Mathematical performance was measured in fall and spring in prekindergarten and spring in kindergarten and first grade using the Test of Early Mathematics Ability–3 (TEMA-3; Ginsburg & Baroody, 2003). Two dimensions of the Classroom Assessment Scoring System (CLASS; i.e., instructional learning formats and concept development; Pianta, La Paro, & Hamre, 2008) were scored based on observed classroom mathematics activities. Teachers provided information about their education and years of prekindergarten teaching experience. Research Findings: Instructional processes that included elements of the CLASS concept development dimension, such as discussions and brainstorming to encourage children’s understanding, were related to growth of mathematics scores. Neither teacher characteristics nor instructional processes of the CLASS instructional learning formats dimension, such as using different modalities and materials, and learning objectives, were related to growth of mathematics scores. Practice or Policy: The findings extend our understandings of how instructional processes impact children’s early mathematical performance. These findings may be helpful in increasing our understanding of the types of instructional processes that might be emphasized in teacher professional development specifically related mathematical activities. Professional development that focuses on the CLASS concept development dimension may be easier for teachers to remember and implement in their classrooms and, consequently, have a greater impact on mathematics learning.  相似文献

We investigated the premise that observation measures of instruction are indicators of effective teaching, using the definition of effectiveness articulated by departments of education: teaching that boosts student achievement. We argued that student motivation is equally as important as achievement in the evaluation of teaching effectiveness (TE); therefore, we examined students' (N = 145) achievement and motivation outcomes. We scored 40 lessons (from 10 kindergarten teachers) with two TE observation measures: the content-independent Classroom Assessment Scoring System (CLASS) and the content-specific Reformed Teaching Observation Protocol (RTOP). We found that the two measures' scores were related differently to student outcomes. Instructionally supportive practices (CLASS and RTOP total) predicted achievement and motivation. Emotional support (CLASS) was positively related to motivation but not to achievement. Classroom organization (CLASS) was negatively related to both motivation and achievement. The CLASS total score did not predict student outcomes; its use masked differences across domains of teaching practices.  相似文献

Research Findings: A statewide study of preschool classroom quality was conducted using 3 distinct classroom observation measures in order to inform a statewide quality rating system. Findings suggested that Tennessee preschool classrooms were approaching “good” quality on the Early Childhood Environment Rating Scale–Revised (ECERS-R) and provided a mid-to-high emotional and engaging climate as indicated by the Classroom Assessment Scoring System (CLASS) domains of Emotional Support and Student Engagement. However, classrooms were only minimal on the Early Childhood Environment Rating Scale–Extension and the CLASS Instructional Support domain. Past performance on a state quality rating assessment consistently predicted the current quality of preschool classrooms as assessed by all 3 measures. Lead teachers' education in early childhood and experience were also predictors across quality measures. Practice or Policy: Tennessee preschool classrooms scored higher on the ECERS-R, which is the measure utilized in the statewide Quality Rating and Improvement System. However, classrooms generally performed poorly on measures of instructional support and curriculum. This finding illuminates the importance of the tool selected to measure quality in state quality rating and improvement systems and has implications for policy as states work to build systems that enhance quality in early care and education.  相似文献

Quality of teacher–child interactions is central to prekindergarten children's learning. In the United States, the quality of teacher–child interactions is commonly assessed using the teaching through interactions conceptual framework and an associ/ated observational tool, the Classroom Assessment Scoring System (CLASS). This study examined: (a) whether there was evidence supporting three distinctive domains of teacher–child interactions in Chile (construct validity) and (b) whether these domains predicted end‐of‐prekindergarten language, academic, and executive function skills in Chile (predictive validity). The sample consisted of 91 Chilean prekindergarten classrooms (1,868 four‐year‐old children). The findings support both construct and predictive validity of the teaching through interactions conceptual framework as assessed by the CLASS in Chile. Implications for cross‐country comparison of quality of teacher–child interactions in prekindergarten classrooms are discussed.  相似文献

Research Findings: This study examined the validity and reliability of the Classroom Assessment Scoring System (CLASS; R. C. Pianta, K. M. La Paro, & B. K. Hamre, 2008) in Finnish kindergartens. A pair of trained observers used the CLASS to observe 49 kindergarten teachers (47 female, 2 male) on two different days. Questionnaires measuring teachers' efficacy beliefs, exhaustion at work, and classroom interactional style (i.e., affection, behavioral control, and psychological control) were completed by the teachers. Confirmatory factor analysis indicated that when the item measuring Negative Climate was excluded, the 3-factor solution assuming three positively correlated latent factors (i.e., Emotional Support, Classroom Organization, and Instructional Support) described classroom quality well. The CLASS also showed high item and scale reliabilities. Evidence for concurrent validity was indicated by the positive association between observed classroom emotional support and teacher-rated affection and self-efficacy. Teacher-rated affection was also associated with observed classroom organization. Practice or Policy: The findings provide support for the CLASS as a valid and reliable measure of classroom quality in kindergartens and in cultural contexts outside the United States.  相似文献

Research Findings: The purpose of the current study was to evaluate the structural validity of scores on a measure of global classroom quality, the Classroom Assessment Scoring System (CLASS K–3; Pianta, La Paro, &; Hamre, 2008 Pianta , R. C. , La Paro , K. M. , &; Hamre , B. K. ( 2008 ). The Classroom Assessment Scoring System manual, K-3 . Baltimore , MD : Brookes . [Google Scholar]). Using observational data from a sample of 417 kindergarten classrooms from the southern and mid-Atlantic regions of the United States, we used confirmatory factor analysis to examine the structural validity of the CLASS K–3. Factor analytic findings supported a 3-factor and 10-dimension structure for the CLASS K–3; however, some modifications were made to the original CLASS model. Practice or Policy: Although the overall structure of the CLASS has been generally consistent across validation studies, some facets of the model may be less stable than others. Additional examination of alternative factor structures is needed to further clarify the relationships among the CLASS dimensions and domains. Current psychometric evidence provides support for continued use of the CLASS to guide intervention, instruction, and professional development.  相似文献

Research Findings: This study examined the association between interactive book reading quality and prekindergarten children’s gains in language and literacy skills over the course of an academic year for 96 teachers and 417 children across multiple locations in the United States. Two moderators were examined, namely, children’s initial skill level and teachers’ classroom organization during an interactive read-aloud session. In keeping with prior research, interactive book reading quality, measured by examination of teachers’ extratextual talk, was positively and significantly related to children’s development of both language and literacy skills. Interactive book reading quality was not significantly moderated by children’s initial skills, with the exception that interactive book reading quality appeared most beneficial to children’s print knowledge for children entering prekindergarten with relatively low skill. The unique contribution of this study is that the association between interactive book reading quality and children’s expressive vocabulary was dependent on an organized classroom during the book reading session. Practice or Policy: The quality of teachers’ talk during interactive book reading may matter for children’s vocabulary development only when reading sessions are characterized by relatively high classroom organization. Classroom organization should be an important consideration while planning for interactive book reading sessions.  相似文献

Research Findings: The growing body of literature demonstrating the importance of quality interactions with caregivers to infant development coupled with the increasing number of infants spending time in classroom settings highlights the need for a measure of interpersonal relationships between infants and caregivers. This article introduces a new measure of quality in infant classrooms based on the Classroom Assessment Scoring System (CLASS) framework. This measure focuses on teacher–infant interactions with the goal of understanding how these proximal process features can be assessed in this environment. Results from a small pilot study of 30 infant classrooms indicated that the CLASS–Infant demonstrated adequate variability as well as expected convergent and divergent validity with the most commonly used infant child care quality measure. The dimensions of the measure composed a single construct of classroom quality based on teacher–infant interactions. Practice or Policy: Implications of using this measure as an assessment of center-based infant classroom quality and improving professional development are discussed.  相似文献

Research Findings: Big Math for Little Kids (BMLK) is a mathematics curriculum developed for use with 4- and 5-year-old children. To investigate the BMLK curriculum's effect on children's mathematics knowledge, this cluster-randomized controlled trial randomly assigned child care centers to provide mathematics instruction to children, using either the BMLK mathematics curriculum or the centers’ business-as-usual curriculum, over a 2-year period when children were in prekindergarten and kindergarten. Participants in the study were 762 children and their teachers at 16 publicly subsidized child care centers. The study assessed children's mathematics knowledge using the Early Childhood Longitudinal Study, Birth Cohort (ECLS-B), Direct Mathematics Assessment, a measure of young children's mathematics knowledge that is not aligned with the curriculum. The ECLS-B scores of children in the BMLK group increased significantly more than did those of children in the comparison group. The study also included exploratory analyses to examine whether children in the BMLK group demonstrated evidence of improved mathematical language. Practice or Policy: These results indicate that the BMLK curriculum, which is designed to help teachers use play-based, developmentally appropriate mathematics instruction, has a positive impact on young children's mathematics knowledge as measured by a general mathematics assessment that is not aligned with the curriculum.  相似文献

Research Findings: A difficulty for developmental researchers is disambiguating children's general maturation from the influence of schooling. In this study, we use a natural experiment to examine the influence of prekindergarten and kindergarten schooling experiences on the development of literacy and mathematics. Children (n = 60) whose birthdates fell within 2 months of the state-determined cutoff date for prekindergarten and kindergarten entry were administered 4 subtests of the Woodcock–Johnson III Tests of Achievement in the fall and spring of the school year. Using hierarchical linear modeling coupled with propensity score matching, we found that children who were starting kindergarten and who had prior experience in prekindergarten had higher scores on measures of phonological awareness, early reading, and mathematics skills than did children who had not attended prekindergarten previously, even though they were essentially the same age. Fall vocabulary scores did not differ in relation to whether children had prekindergarten experience. In addition, although children who attended kindergarten as well as those who attended prekindergarten exhibited growth on all measures during the school year, children who attended kindergarten demonstrated greater gains in early reading and vocabulary during the school year. Practice or Policy: These findings highlight the potential of early schooling processes to facilitate children's intellectual growth.  相似文献

The Classroom Assessment Scoring System (CLASS; Pianta et al., 2008) is a popular measure of teacher–child interactions. Despite its prominence, CLASS scores have fairly weak relations with various child outcomes (e.g., Zaslow et al., 2010). One potential reason for these findings could be systematic differences in observer severity. As such, the purpose of this study was to explore the scope and impact of rater effects on CLASS scores with a sample of 77 teachers who were rated by 13 observers. Results indicated significant rater effects across all three CLASS domains. Adjusting for these effects, however, did not improve relations between CLASS scores and child outcomes. Implications for the CLASS and related assessments are discussed.  相似文献

Research Findings: This study examined the applicability of the Classroom Assessment Scoring System (CLASS) Pre-K (Pianta, La Paro, & Hamre, 2008) and its underpinning framework of teaching through interactions in typical Chinese kindergarten classrooms. A sample of 180 kindergarten classrooms in China was selected, and the CLASS was used to rate the classroom teaching interactions. Multiple analytical approaches were applied to examine how the CLASS functioned in the Chinese cultural and social context, including score pattern comparisons with samples from the United States and some international contexts, measurement reliability analysis for different measurement error sources (e.g., interrater reliability and stability across time), and confirmatory factor analysis for several competing models. The findings from these different analyses indicated that the CLASS exhibited the same or very similar structures as in the U.S. sample, and the ratings of the CLASS showed other desirable psychometric characteristics. Practice or Policy: The evidence from the multiple analytical approaches provide strong support for the applicability of the CLASS in the Chinese context. The findings also reveal a critical need for Chinese teachers to improve the quality of instructional support in order to promote children’s optimal development. Limitations are noted, and future research directions are discussed.  相似文献

This case study involved examination of the evolution of mathematical beliefs of three prekindergarten teachers. The researcher followed three teachers at one school in west Alabama over the course of 6 months as they implemented a new mathematics curriculum in their pre-K classrooms. Interviews were conducted prior to implementation and at the end of the school year. Classroom observations were done throughout the implementation process. Three themes emerged from the data (a) math resources for the pre-K classroom, (b) pushing beyond—thinking mathematically, and (c) instructional strategies used the pre-K classroom. These themes revealed how all of the teachers' perceptions of early childhood mathematics curriculum and instruction evolved during the course of the study. These findings have implications for early childhood teacher education programs and professional development.  相似文献

Research Findings: This study examined the potential impacts of ongoing participation (twice weekly for 30 weeks) in teacher–child managed whole-group language and literacy instruction on prekindergarten children’s social interaction with classmates. Teacher–child managed whole-group instruction that provides children with opportunities to engage with all of their classmates regularly may potentially deepen the social depth within a classroom (i.e., the frequency with which children regularly interact with each other). Provision of this type of instruction occurred via teachers’ implementation of a whole-class literacy curriculum twice weekly. Participants were 119 preschoolers who received an experimental literacy curriculum in 26 classrooms and 76 children in 17 business-as-usual control classrooms. Condition predicted the strength of children’s social interaction, suggesting that children in experimental classrooms had relatively stronger social ties with peers than children in control classrooms. Practice or Policy: The findings suggest that participation in ongoing teacher–child managed whole-group instruction could facilitate stronger social connections among preschool children.  相似文献

Research Findings: We evaluated the score stability of the Mathematical Quality of Instruction (MQI), an observational measure of mathematics instruction. Three raters each scored, independently, 100 video-recorded lessons taught by 20 kindergarten teachers in the spring. Using generalizability theory analyses, we decomposed the MQI’s score stability into potential sources of variation (teachers, lessons, raters, and their interactions). The 13-item (3-domain) Ambitious Mathematics Instruction scale and the Whole Lesson scale each explained about one third of the variance attributed to differences in the main construct of interest (teachers’ instructional strategies). The MQI’s Errors and Imprecision scale was not relevant at the kindergarten level; there were virtually no errors and/or ambiguities observed across the 100 mathematics lessons. In a series of decision studies, we examined improvements in reliability with combinations of up to 6 raters and 8 lessons. Only the Richness of Mathematics domain scores and the Whole Lesson scores achieved acceptable reliabilities. Practice or Policy: The findings have important implications for the use of observation measures to document teachers’ mathematics practices in the early years of school.  相似文献

Abstract

The Classroom Assessment Scoring System (CLASS) has been used extensively to measure teacher-student interactions and classroom quality. With a theoretical foundation rooted in the developmental theory of learning, CLASS has three primary domains—Emotional Support, Classroom Organization, and Instructional Support. In this study, we performed a meta-analysis of the factor structure of CLASS using Cheung’s two-stage structural equation modeling (TSSEM) approach. After searching the literature, we obtained 26 correlation matrices of the 10 dimensions shared by multiple versions of CLASS. This meta-analysis supports the three-factor model initially proposed by CLASS developers. The finding of this meta-analysis provides important evidence pertinent to the CLASS factor structure and has significant implications regarding the interpretation and use of CLASS scores.  相似文献

High-quality child care is related to children's positive developmental outcomes. One way to increase quality of care is to provide training to child care providers. This study used assessment-based training to determine if overall quality of care in center-based preschools could be enhanced. Participants were recruited from six center-based child care programs serving preschool-age children and included program administrators, teachers, teacher aides, and enrolled children. Program administrators (N?=?6) were assessed with the Program Administration Scale (Talan & Bloom, 2004), classrooms (N?=?14) with the Early Childhood Environment Rating Scale Revised (ECERS-R; Harms, Clifford, & Cryer, 2005) and the Early Language and Literacy Classroom Observation—Research Edition (ELLCO; Smith & Dickinson, 2002), teachers (N?=?24) with the Classroom Assessment Scoring System (CLASS; Pianta, La Paro, & Hamre, 2007), and children (N?=?135) with an author-created measurement designed to assess typical skills across five child domains. Assessments were administered at two time points and individualized targeted training was provided in between. Results demonstrated that after 7 months of intervention, the largest effect sizes were seen at the program administration and classroom levels and that smaller effect sizes were found at the teacher and child levels.  相似文献

Research Findings: Public policy has increasingly focused on expansion of preschool access for underserved students and systematic evaluation of preschool quality and students’ readiness for school. However, such evaluation is limited by a lack of thoroughly validated assessments for use with preschool populations. The present study examined the measurement and structural invariance of the Kindergarten Student Entrance Profile (KSEP) across kindergarten and prekindergarten groups to evaluate its potential use across developmental groups. Participants included 522 kindergarten and 548 prekindergarten students in central California. Invariance was tested by fitting a series of multiple-groups confirmatory factor analysis models with parameter constraints across groups. Results indicated that measurement and structural parameters of the KSEP were invariant across kindergarten and prekindergarten groups. Prekindergarten means on both Social–Emotional Readiness and Cognitive Readiness were significantly lower than kindergarten means. Practice or Policy: These results suggest that the KSEP may potentially be used with prekindergarten students to assess school readiness and inform intervention before kindergarten entry.  相似文献

In this study we examined the impact of a year long model of professional development comprised of a monthly cycle of video-based self-reflection, peer coaching, and mentoring and bimonthly workshops focused on selected Classroom Assessment Scoring System (CLASS) dimensions. Education supervisors were trained and supported by project staff to lead coaching sessions with a team of teachers. Monthly changes in the quality of teacher–child interactions as measured by CLASS were examined. The intervention group (n = 38) was significantly different than a comparison group (n = 22) at the end of the year. There were significant increases in four dimensions related to behavior management, productivity, language modeling and quality of feedback. Similar patterns of change were found for teachers with and without college degrees. Effective instructional practices can be developed and implemented by teachers when they are provided multiple opportunities to engage in sustained professional development experiences based on a valid observational measure. Implications for designing cost effective CLASS-based professional development as well as limitations of this study are discussed.  相似文献
