The case for frequency sensitivity in orthographic learning

This paper positions the importance of frequency sensitivity in the development of orthographic knowledge throughout childhood and promotes learning to spell as a vehicle which may be used effectively to develop this sensitivity. It is suggested that orthographic knowledge is advanced via a process of ‘frequency sensitivity’ to ‘patterns and sequences’ and ‘rules and regularities’ particular to English orthography and that the process of sensitivity to these coarse grain orthographic patterns is influenced by consistency in sound and by morphological knowledge (knowledge of morphemes; words or word parts that form the smallest unit of meaning in language). A model highlighting the increasing importance of orthography and morphology as reading and spelling development progresses is presented. Discussion of the importance of considering phonology, orthography and morphology throughout literacy development and the relative importance of each is discussed. Distinctions are drawn between the processes involved in children who are good readers and good spellers, children who are good readers and poor spellers, and children who are poor readers and poor spellers. This paper outlines how considering these interrelated and developmentally sensitive contributors to literacy development can contribute to the practice of educational professionals in promoting the development of literacy skills throughout childhood.     

Assessment of the Joint Food Science Curriculum of Washington State University and the University of Idaho by Graduates and Their Employers

ABSTRACT: Thirty-two recent graduates from the joint food science program of Washington State Univ. (WSU) and The Univ. of Idaho (UI) and 12 of their employers participated in a survey study to assess food science program outcomes. The objective of this study was to assess the joint curriculum in its ability to prepare undergraduate students for critical thinking, problem solving, and technical competence in the food industry. Two survey tools, 1 for graduates and 1 for their employers, were designed to assess job preparedness and the skill set attained by food science program graduates. Graduates of the joint food science program generally indicated satisfaction with their food science education and suggested that they were adequately prepared for their jobs. Both students and employers indicated that most of the identified Success Skills are used daily on the job, and that graduates were well prepared with Success Skills. Graduates and employers reported adequate preparation in Food Processing and Engineering competence. Some significant differences ( P < 0.05) were found in perceived and assessed competence. Specifically, while student indicated that they were well prepared with Food Chemistry and Analysis, Food Safety and Microbiology, and Applied Food Science competence, employers indicated only adequate preparation in Food Chemistry and Analysis, and Applied Food Science competence, but poor preparation in Food Safety and Microbiology competence. The findings suggest that students should be given opportunities for self-evaluation in undergraduate courses. Because the survey models are based on Institute of Food Technologists requirements, it is expected that the surveys can be readily adopted by other institutions to assess student learning and program effectiveness.     

Using Historical Nonfiction and Literature Circles to Develop Elementary Teachers’ Nature of Science Understandings

Explicit instruction of the nature of science (NOS) may be problematic if the NOS is portrayed as either a solely a cognitive or discursive endeavor, overlooking other aspects of epistemology, such as aesthetic ways of knowing. Here the aesthetic stance refers to individual’s responses during reading as they create links between the text and their own lives, prompting personal and emotional connections. From an aesthetic orientation, exploring historical nonfiction science texts via literature circles allows alternative possibilities for participants to create personal connections to the NOS. This article presents practical techniques and theoretical rationales for teaching the NOS using literature circles and concluding thoughts regarding narrative pedagogy and research possibilities associated with this instructional approach in elementary science teacher education.     

Preschool outcomes of children of depressed mothers: role of maternal behavior,contextual risk,and children's brain activity

Children of depressed mothers are at risk for behavioral and emotional problems. Infants of depressed mothers exhibit behavioral disturbances and atypical frontal brain activity. The mechanisms by which children develop such vulnerabilities are not clear. Three-year-old children of mothers with (N = 65) and without (N = 59) a history of depression were assessed in terms of behavior problems and brain electrical activity. Children of mothers with chronic depression exhibited lower frontal and parietal brain activation compared with children of mothers without depression and those whose depression remitted. Depressed mothers reported higher contextual risk (e.g., marital discord and stress) and their children had more behavior problems. Children's frontal brain activation and contextual risk level mediated the relation between maternal depression and child behavior problems.     

What to do about values in social research: the case for ethical reflexivity in the sociology of education

This paper is intended as a contribution to the longstanding debate about the best way of handling value judgements in social research. In it we make a case for more ‘ethical reflexivity’ in the sociology of education and argue that a systematic attention to value questions should be viewed as a taken‐for‐granted component of methodological rigour. We elucidate what we mean by ethical reflexivity, why we think it is important and suggest what it entails in practice. Our arguments are developed through a discussion of, and in contrast to, Martyn Hammersley’s analysis of the role of values in social research. The central problematic that the paper addresses is the tension between, on the one hand, the goal of insulating the research process from ‘value bias’ and, on the other hand, the goal of contributing to political and social change through research. We suggest that the reason for the intractability of the problem of values in social research is a persistent failure to recognise that, in practice, these two goals are inseparable. We argue that rigour in research demands that both these goals are taken seriously and we set out some of the challenges involved in trying to combine them.     

Ability grouping and science education reform: Policy and research base

This article reviews current policy trends concerning the practice of ability grouping in K–12 science education. Relevant statements of key policy-making, policy-influencing organizations such as the NSTA, AAAS, NSF, the National Research Council, the U.S. Office of Education Department of Civil Rights, NAACP, the National Governors' Association, programs related to the Jacob Javits Grants for the Gifted and Talented, and others are summarized. The author's interpretation of the various positions are presented herein. The article also explores the research base supporting the various policies on grouping by examining selected general research literature on grouping, followed by research that is science education specific. Methodological issues color the research findings. The ethical and pragmatic implications of developing research and policy are discussed. The conclusions are that there is a dearth of recent empirical research specifically related to ability grouping in science, and that the time is ripe for the concerted development of a research agenda by key players in science education reform. Moreover, as controversial and value-laden as the topic is, it should be noted that grouping practices alone are unlikely to influence science education reform unless considered in the context of comprehensive restructuring efforts at the local school level.     

Polynesian Folklore: An Alternative to Plastic Toys

Because folklore has the capability to teach and to preserve the thoughts, feelings, and beliefs of a people, suggestions are offered for using folklore to deepen children's understanding of Polynesian culture. Maori nature fables, along with error/punishment stories involving the woman or man on the moon, represent the instructive function. Tales and legends preserving cultural history are represented by a folk story reflecting values and customs of everyday life, accounts of legendary monsters reflecting cultural hopes and fears, and heroic tales of the popular demigod Maui. Specific stories are reviewed, juvenile collections are referenced, and classroom activities are offered.     

Images in mirrors: Recollections,alternative explanations and modes of cognitive functioning

Students' conceptions of how objects are seen directly, and in mirrors, were explored in an analysis of their written and drawn responses to common visual phenomena depicted in cartoons with brief text. Students in Grades K-10 (n=214) completed a questionnaire and some were interviewed. Evidence was sought to support an hypothesis for increasingly sophisticated responses related to the concepts of sight, light, reflection and image. The developmental model used in this analysis was the updated SOLO Taxonomy (Biggs & Collis, 1991; Collis & Biggs 1991). It appears from the results that different modes of functioning can interfere to produce factually incorrect recollections of experience particularly in the age group 7 to 13 years approximately. Also, this is associated with the common spurious conception that mirrors have a lateral inversion property. Explanations involving light were extremely rare and its role related to the production of an image ‘in the mirror’ but not to the perception of an image in the eyes.
