The Child Care Ecology Inventory: A domain-specific measure of home-based child care quality to promote social competence for school readiness

This study investigates the reliability and validity of the Child Care Ecology Inventory (CCEI), a measure of the quality of family child care in the social domain. The CCEI focuses on research-based environmental features and caregiving practices for promoting positive social development in preschool-age children. A total of 198 family child care homes in the Northwest USA participated. Good scale reliabilities were found for the measures of the environment (Enrichment and Organization) and for caregivers’ practices (Monitoring, Positive Attention, Promoting Social Skills, and Teaching Rules) and interrater reliability was adequate for research purposes. The CCEI was associated with other commonly used measures of child care quality that assessed similar environmental and caregiving constructs. Linear regression models were run to determine the features of family child care quality that were concurrently associated with observed child behavior. The child–caregiver ratio, Environment Organization, and caregivers’ Teaching Rules were negatively associated with children's problem behavior (noncompliance and aggression). Caregivers’ provision of Planned Activities/Routines and Positive Attention were associated with positive child behavior. Results indicate that different aspects of quality are related to different aspects of children's social interactions and behaviors.     

The impact of a systematic and explicit vocabulary intervention in Spanish with Spanish-speaking English learners in first grade

This study examined the impact of a 15-min daily explicit vocabulary intervention in Spanish on expressive and receptive vocabulary knowledge and oral reading fluency in Spanish, and on language proficiency in English. Fifty Spanish-speaking English learners who received 90 min of Spanish reading instruction in an early transition model were randomly assigned to a treatment group (Vocabulary Enhanced Systematic and Explicit Teaching Routines [VE-SETR]) or a comparison group that received general vocabulary instruction using the standard reading curriculum with general strategies designed to increase the explicitness of instruction (General Systematic and Explicit Teaching Routines). Results indicated a statistically significant difference in depth of student Spanish vocabulary knowledge favoring the VE-SETR group. Differences on language proficiency in English, general vocabulary knowledge in Spanish, and oral reading fluency in Spanish were not statistically significant. Implications for future research are discussed.     

Developing an Understanding of Chemistry: A case study of one Swedish student's rich conceptualisation for making sense of upper secondary school chemistry

In this paper, we report a case study of a 16-year-old Swedish upper secondary student's developing understanding of key concept areas studied in his upper secondary school chemistry course. This study illustrates how the thinking of an individual learner, Jesper, evolves over a school year in response to formal instruction in a particular educational context. Jesper presented a range of ideas, some of which matched intended teaching whilst others were quite inconsistent with canonical chemistry. Of particular interest, research data suggest that his initial alternative conceptions influenced his thinking about subsequent teaching of chemistry subject matter, illustrating how students' alternative conceptions interact with formal instruction. Our findings support the claims of some researchers that alternative conceptions may be stable and tenacious in the context of instruction. Jesper's rich conceptualisation of matter at submicroscopic scales drew upon intuitions about the world that led to teaching being misinterpreted to develop further alternative conceptions. Yet his intuitive thinking also offered clear potential links with canonical scientific concepts that could have been harnessed to channel his developing thinking. These findings support the argument that identifying students' intuitive thinking and how it develops in different instructional contexts can support the development of more effective science pedagogy.     

Shifting sands: a case study of conceptual development as competition between alternative conceptions

Conceptual change may be considered as a process of coming to view one theory or model as having more explanatory power than others. Various theorists have described how an individual's understanding of a concept may be multifaceted; how conceptual frameworks develop in a cognitive ecology, and are subject to selection pressures; and how alternative frameworks compete in terms of their explanatory coherence. The present paper applies these ideas to a case study of learning in science. It is argued that conceptual development may be described in terms of a gradual shift in which of several alternative explanatory principles is the learners' preferred choice. The case study illustrates the long-term nature of conceptual change, as a learner comes to see the limitations of one explanatory framework, and the scope for exploring and developing another.     

What’s in a Name: Differential labelling of plant and animal photographs in two nationally syndicated elementary science textbook series

This study investigated plant and animal photographs in elementary science textbooks to discern whether there were disparities in the number of plant and animal photographs or in how those photographs were labelled. We examined the Life Science sections of two nationally syndicated (USA) textbook series. For each text, we identified the photographs with plant and/or animal content and evaluated them for two features: (1) the subject of the photograph, and (2) the specificity of the label (name) provided. We found that photographs with animal subjects were more numerous than those with plant subjects; they also represented a greater diversity of animals and had a higher instance of repetition than did plant photographs. We also found a significant naming disparity: animal photographs were three times more likely to be provided with a specific label (common name) than were plant photographs. Not only were plant photographs less likely to be provided with a specific name for the plant (e.g. orchid or dandelion), but also they were commonly identified only by the name for a plant part (such as flower or leaf) or life‐form (e.g. tree or shrub). To address the disparity revealed by this study, and to encourage student interest in and knowledge about plants, we recommend that educators go beyond textbooks to expose students to a diversity of named plants, and present plants as distinct organisms rather than as a collection of parts.     

Conceptions of assessment: trainee teachers' practice and values

This study examines the values and practice in relation to assessment of a sample of 220 trainee teachers studying for a Postgraduate Certificate in Education, an initial teacher training and education (ITET) course, at the University of Cambridge, UK. The survey instrument was drawn from James and Pedder (2006 James, M. and Pedder, D. 2006. Beyond method: Assessment and learning practices and values. The Curriculum Journal, 17(2): 109–138. [Taylor & Francis Online] , [Google Scholar]), and was composed of questionnaire items that sought to elicit how trainees valued different classroom assessment practices, and the extent to which their own teaching complied with such values. The study draws additionally on the findings of James and Pedder (2006 James, M. and Pedder, D. 2006. Beyond method: Assessment and learning practices and values. The Curriculum Journal, 17(2): 109–138. [Taylor & Francis Online] , [Google Scholar]) to compare and contrast results with those for qualified teachers. Item and factor analyses revealed three dimensions that underpin trainees' classroom practice and values (promoting learning autonomy, performance orientation, making learning explicit). Values-practice gaps were greatest on promoting learning autonomy and performance orientation. Trainees valued practices associated with the former more than they implemented them in their teaching, while they implemented practices associated with the latter more than predicted by their values. Values-practice gaps suggested that trainees were constrained from implementing their values to a greater extent than qualified teachers, particularly with respect to these two factors.     

English secondary students’ thinking about the status of scientific theories: consistent,comprehensive, coherent and extensively evidenced explanations of aspects of the natural world – or just ‘an idea someone has’

Teaching about the nature of science (NOS) is seen as a priority for science education in many national contexts. The present paper focuses on one central issue in learning about NOS: understanding the nature and status of scientific theories. A key challenge in teaching about NOS is to persuade students that scientific knowledge is generally robust and reliable, yet also in principle always open to challenge and modification. Theories play a central role, as they are a form of conjectural knowledge that over time may be abandoned, replaced, modified, yet sometimes become well established as current best scientific understanding. The present paper reports on findings from interviews with 13–14 year olds in England where target knowledge presents theories as ‘consistent, comprehensive, coherent and extensively evidenced explanations of aspects of the natural world’. Student thinking reflected a two-tier typology of scientific knowledge in which largely unsupported imaginative ideas (‘theories’) became transformed into fairly definitive knowledge (such as laws) through relatively straightforward testing. These results are considered in relation to research into intellectual development which indicates that effective teaching in this area requires careful scaffolding of student learning, but has potential to contribute to supporting intellectual development across the curriculum.
