Depression, Control, and Climate: An Examination of Factors Impacting Teaching Quality in Preschool Classrooms.

Research Findings: This study investigated the relationship of preschool teachers’ self-reported depressive symptomatology, perception of classroom control, and perception of school climate to classroom quality as measured by the Classroom Assessment Scoring System Pre-K. The sample consisted of 59 urban preschool classrooms serving low-income and linguistically diverse students in the northeastern and southeastern United States. Results of hierarchical linear modeling revealed that teachers’ individual reports of depressive symptomatology were significantly and negatively predictive of the observed quality of their instructional support and classroom organization. Practice or Policy: The findings of this study have implications for increasing access to mental health supports for teachers in an effort to minimize depressive symptoms and potentially improve classroom quality.

Measuring Quality in Kindergarten Classrooms: Structural Analysis of the Classroom Assessment Scoring System (CLASS K-3).

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). 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.

Preschool teachers’ language and literacy practices with dual language learners

ABSTRACT The purposes of this study were to (a) examine the degree to which teachers used linguistically responsive practices to support the language and literacy development of Spanish-speaking Dual Language Learners (DLL) and (b) to investigate the associations between these practices and select teacher-level factors. The sample consisted of 72 preschool teachers. Observational data were collected on practices. Teachers self-reported on language and culture beliefs, Spanish-speaking ability, and classroom composition. Results indicated that teachers, including those who spoke Spanish, used few linguistically responsive practices to support preschool DLLs. Only Spanish-speaking ability was related to practices. Implications for targeted professional development are discussed.

Relations among the Home Language and Literacy Environment and Children's Language Abilities: A Study of Head Start Dual Language Learners and Their Mothers.

ABSTRACT Research Findings: This study explored the relations between Spanish–English dual language learner (DLL) children’s home language and literacy experiences and their expressive vocabulary and oral comprehension abilities in Spanish and in English. Data from Spanish–English mothers of 93 preschool-age Head Start children who resided in central Pennsylvania were analyzed. Children completed the Picture Vocabulary and Oral Comprehension subtests of the Batería III Woodcock–Muñoz and the Woodcock–Johnson III Tests of Achievement. Results revealed that the language spoken by mothers and children and the frequency of mother–child reading at home influenced children’s Spanish language abilities. In addition, the frequency with which children told a story was positively related to children’s performance on English oral language measures. Practice or Policy: The findings suggest that language and literacy experiences at home have a differential impact on DLLs’ language abilities in their 2 languages. Specific components of the home environment that benefit and support DLL children’s language abilities are discussed.

Structural Validity of CLASS K-3 in Primary Grades: Testing Alternative Models.

This study examined the internal structure of the Classroom Assessment Scoring System (CLASS; K–3 version). The original CLASS K–3 model (Pianta, La Paro, & Hamre, 2008) and 5 alternative models were tested using confirmatory factor analysis with a sample of first- and second-grade classrooms (N = 141). Findings indicated that a slightly modified version of the original CLASS K–3 3-factor model best fit the current data. Although stable findings emerged across the current and previous studies, particularly in relation to the presence of 3 latent domains, there is also some variability across structures at different grade levels with regard to the bifactor and 3-factor models.

Social Validity of the Social Skills Improvement System--Classwide Intervention Program (SSIS-CIP) in the Primary Grades.

The purpose of this study was to examine the social validity of the Social Skills Improvement System-Classwide Intervention Program (SSIS-CIP) for teachers in the primary grades. Participants included 45 first and second grade teachers who completed a 16-item social validity questionnaire during each year of the SSIS-CIP efficacy trial. Findings indicated that teachers generally perceived the SSIS-CIP as a socially valid and feasible intervention for primary grades; however, teachers’ ratings regarding ease of implementation and relevance and sequence demonstrated differences across grade levels in the second year of implementation.

‘So many books they don’t even all fit on the bookshelf’: An examination of low-income mothers’ home literacy practices, beliefs and influencing factors:

Given the need to enhance the academic language and early literacy skills of young children from low-income homes and the importance of the home literacy environment in supporting children’s development, the purpose of this qualitative study was to better understand the home literacy environment of low-income African-American and Latino mothers of preschool children living in the United States. Specifically, research aims were to examine home literacy environment practices, beliefs and influential factors as well as to compare the home literacy environment of African-American and Latino, specifically Puerto Rican, families. Semi-structured interviews were conducted with 10 African-American and 10 Puerto Rican mothers. Data were analysed using the consensual qualitative research method. Twelve themes were identified: provision of educational materials, engagement with books, focus on print, implicit language opportunities, focus on other pre-academic skills, social interactions with books, influence of school, influence of other adults, parents’ reading interest/ability, child’s reading interest, parents’ commitment to child’s success and family stressors. Few differences emerged between African-American and Puerto Rican mothers. Implications for language and literacy intervention development are discussed.

Variations in Classroom Language Environments of Preschool Children Who Are Low Income and Linguistically Diverse

ABSTRACT Research Findings: This study aimed to (a) provide an in-depth description of the frequency and type of language interactions that children who are low income and/or dual language learners (DLLs) experience in their classrooms and (b) examine whether differences exist in children’s language experiences based on children’s DLL status and level of English proficiency. Using the Language Interaction Snapshot, we observed 4 focal children in each of 72 early childhood classrooms: 1 monolingual English-speaking child (i.e., non-DLL), 1 Spanish-dominant DLL child, and 2 bilingual Spanish–English DLL children. Findings indicated that both lead and assistant teachers predominantly spoke in English and implemented few evidence-based language practices. Children spoke more often to peers than to teachers. Little variation was noted in the quality of the language environment for children based on their DLL status or language proficiency. Practice or Policy: Results suggest clear directions for professional development (PD). PD must include both lead and assistant teachers and should focus on evidence-based language strategies for facilitating children’s language development, including how to effectively teach DLLs. Teachers may also benefit from PD that supports the use of small-group activity and peer strategies.

Does Teaching Quality Cross Subjects? Exploring Consistency in Elementary Teacher Practice Across Subjects

Teacher evaluation systems treat instructional quality as generic. Principals often observe elementary teachers in one subject and generalize assessments to all subjects. However, there is little empirical work to justify these decisions. This study provides needed evidence about whether elementary teachers engage in comparable instruction across the school day. We draw on data from the Measures of Effective Teaching (MET) project, including student survey and classroom observational data from more than 500 elementary teachers. Findings indicate that there is moderate within-teacher, cross-subject consistency on the Tripod and Classroom Observation Scoring System (CLASS). Cross-subject correlations are higher on the Tripod scales (r values from 0.55 to 0.73) than the CLASS dimensions and domains (r values from 0.25 to 0.55). These findings suggest that teaching quality is not a uniform construct across subjects, even though current teaching evaluation systems largely treat it as such. Implications for elementary teacher preparation, professional development, and evaluation are discussed.

Analysis of Bilingual Children’s Performance on the English and Spanish Versions of the Woodcock-Muñoz Language Survey-R (WMLS-R)

The purpose of this study was to investigate the way in which items on the Woodcock-Muñoz Language Survey Revised (WMLS-R) Spanish and English versions function for bilingual children from different ethnic subgroups who speak different dialects of Spanish. Using data from a sample of 324 bilingual Hispanic families and their children living on the United States mainland, differential item functioning (DIF) was conducted to determine if test items in English and Spanish functioned differently for Mexican, Cuban, and Puerto Rican bilingual children. Data on child and parent language characteristics and children’s scores on Picture Vocabulary and Story Recall subtests in English and Spanish were collected. DIF was not detected for items on the Spanish subtests. Results revealed that some items on English subtests displayed statistically and practically significant DIF. The findings indicate that there are differences in the difficulty level of WMLS-R English-form test items depending on the examinees’ ethnic subgroup membership. This outcome suggests that test developers need to be mindful of potential differences in performance based on ethnic subgroup and dialect when developing standardized language assessments that may be administered to bilingual students.
