Instructional Activities and the Quality of Language in Chilean Preschool Classrooms

Research Findings: This study examines the association between preschool classroom activity and the quality of the language spoken by teachers and children. Eighteen classrooms serving low-income children between the ages of 3 and 4 in Santiago de Chile were audio-recorded during one morning shift. Recordings were transcribed and segmented into activities (greeting, learning experience, book sharing, book discussion, breakfast, lunch, free play and other noninstructional time). A total of 113 activity segments were identified. Characteristics of teacher and child language were measured in each segment. Differences between the eight activities were examined using analysis of variance. Activities were classified as instructional or noninstructional, and the association between this dimension and language characteristics was examined using multilevel path analysis. Results show that most of the variance in language outcomes occurs within classrooms. Analyses show that a significant portion of the variance in the way teachers and children talk is explained by the instructional/noninstructional dimension. Instructional activities are characterized by more language stimulation, more teaching, fewer directives, and more child talk than noninstructional activities. Practice or Policy Implications: We discuss implications for teacher professional development and early childhood education improvement in general and for Latin-America specifically.     

Dynamic assessment: supporting educational psychologists’ practice through the use of video during supervision

ABSTRACT

Dynamic assessment (DA) is appealing to educational psychologists (EPs) due to: its flexibility, allowing EPs to adjust materials and processes to fit the assessment context; its usefulness, revealing ideas about how the next steps for learning might be achieved; and its focus on strengths. In Feuerstein’s words, “it is the instances of success of the individual that are the focal point for analysis for the reasons of success and failure”. Given the appeal of DA, it is frustrating that it has not been taken up more by practitioners. This paper will explore what DA is, and what it is not, summarise its advantages, consider why it is not more widely used, and introduce one way in which EPs can receive support for DA; using video of an EP “doing” DA within supervision in order to reflect on “good” DA.     

The interplay of scientific epistemological views,learning strategies,and attitudes of college students

This paper focuses on research that illustrates the important interplay between students' scientific epistemological views and their learning strategies. We address the problem of facilitating meaningful science learning as contrasted to rote memorization, which is practiced by many students and encouraged by instructional and evaluation practices. We show that when metacognitive tools are used to facilitate meaningful learning, positive consequences in learning of subject matter, attitudes toward science, and epistemological views can emerge. Positivistic epistemology continues to be the subtle enemy to encouraging meaningful learning and constructivist views of the nature of science and knowing. If you're a scientist, you can say that all knowledge is scientific and everything can be based on fact and experiment. I've taken so many science classes that I've started to believe that.     

Scientific explanations: Characterizing and evaluating the effects of teachers' instructional practices on student learning

Teacher practices are essential for supporting students in scientific inquiry practices, such as the construction of scientific explanations. In this study, we examine what instructional practices teachers engage in when they introduce scientific explanation and whether these practices influence students' ability to construct scientific explanations during a middle school chemistry unit. Thirteen teachers enacted a project‐based chemistry unit, How can I make new stuff from old stuff?, with 1197 seventh grade students. We videotaped each teacher's enactment of the focal lesson on scientific explanation and then coded the videotape for four different instructional practices: modeling scientific explanation, making the rationale of scientific explanation explicit, defining scientific explanation, and connecting scientific explanation to everyday explanation. Our results suggest that when teachers introduce scientific explanation, they vary in the practices they engage in as well as the quality of their use of these practices. We also found that teachers' use of instructional practices can influence student learning of scientific explanation and that the effect of these instructional practices depends on the context in terms of what other instructional practices the teacher uses. © 2007 Wiley Periodicals, Inc.

‘If there's a dead rat,don't leave it’. Young children's understanding of their citizenship rights and responsibilities

Concerns about pupil disengagement from school and society have led to compulsory citizenship education in state schools in England. However, there is little evidence that the new citizenship education is meeting its goals. The research described here assesses a new approach to citizenship education that appears to overcome some of the identified obstacles in current practices. Hampshire's ‘Rights, respect and responsibility’ initiative is a rights‐based whole school reform of school policies and practices. Under this initiative the contemporaneous citizenship status of pupils is respected, pupils are taught about their rights under the UN Convention on the Rights of the Child and democratic participation is made meaningful in classroom and school functioning. Of particular interest is that the initiative starts in infant schools. This research indicates that young children can understand their rights and responsibilities in ways that are meaningful to their everyday behaviour and that rights‐based whole school reform has the capacity to improve pupil learning and citizenship behaviours.     

The use of phonological, orthographic, and contextual information during reading: a comparison of adults who are learning to read and skilled adult readers

The purpose of this study was to assess the role that phonological, orthographic, and contextual sources of information play in a group of adults who were learning to read compared to adult skilled readers. Participants read short paragraphs that contained a correct homophone, an incorrect homophone, or a spelling control. Target words were orthographically similar or dissimilar, and they appeared in context that predicted the target or was neutral with respect to the target. The pattern of data obtained for skilled readers was consistent with past work (Rayner et al., Journal of Experimental Psychology: Learning, Memory and Cognition 24(2), 476–497, 1998). Skilled readers showed no reading time differences between the correct homophone and the incorrect homophone, as long as the two were orthographically similar, but reading times on these words were faster than the spelling control condition. The pattern of data for the adults who were learning to read was different. These readers were actually better at noticing that an incorrect version of the homophone was present. Importantly, we did find consistent significant differences between the incorrect homophone condition and the spelling control condition. This suggests the adults who were learning to read use phonological codes during word recognition, but they do so less efficiently than skilled readers.     

24 Hours in the Children’s Section: An Observational Study at the Public Library

The purpose of this study was to explore patronage and usage of the children’s section of a public library. Patrons of the children’s section of a public library in a small Northern Arizona city were observed for a total of 24 h over 12 sessions. Analytic induction was used to formulate categories based on field notes made during these observations. An observation of a story time session was also conducted. Data from an interview with a librarian was triangulated with observational data. In terms of patronage, the clear majority of parents/adult caregivers accompanying a child or children to the children’s section were observed to be female and speaking English. In terms of usage, the following three categories of early learning were identified from the data: early literacy learning; learning how to use a library; and other developmentally appropriate learning. Study results offer insight into both the role of females in the intergenerational transmission of literacy and the rich learning young children experience at the library. At a time of library cutbacks and closures across the United States, this study speaks to the continued relevance of the children’s section of the public library in providing free early learning experiences during the pivotal birth to five age range.     

Not quite normal: Consequences of violating the assumption of normality in regression mixture models

Regression mixture models are a new approach for finding differential effects which have only recently begun to be used in applied research. This approach comes at the cost of the assumption that error terms are normally distributed within classes. The current study uses Monte Carlo simulations to explore the effects of relatively minor violations of this assumption, the use of an ordered polytomous outcome is then examined as an alternative which makes somewhat weaker assumptions, and finally both approaches are demonstrated with an applied example looking at differences in the effects of family management on the highly skewed outcome of drug use. Results show that violating the assumption of normal errors results in systematic bias in both latent class enumeration and parameter estimates. Additional classes which reflect violations of distributional assumptions are found. Under some conditions it is possible to come to conclusions that are consistent with the effects in the population, but when errors are skewed in both classes the results typically no longer reflect even the pattern of effects in the population. The polytomous regression model performs better under all scenarios examined and comes to reasonable results with the highly skewed outcome in the applied example. We recommend that careful evaluation of model sensitivity to distributional assumptions be the norm when conducting regression mixture models.     

The role of negative priming in preschoolers' flexible rule use on the dimensional change card sort task

Four experiments examined the development of negative priming (NP) in 3-5-year-old children using as a measure of children's executive function (EF) the dimensional change card sort (DCCS) task. In the NP version of the DCCS, the values of the sorting dimension that is relevant during the preswitch phase are removed during the postswitch phase. The experiments showed that the NP effect observed in the DCCS decreased during the preschool years, and they clarified the circumstances in which NP occurs. Taken together, the findings suggest that the development of EF in early childhood consists in part in disinhibiting attention to information that has previously been suppressed.
