A Cross-Age Study of the Understanding of Three Genetic Concepts: How Do They Image the Gene, DNA and Chromosome?

The study was carried out with 175 Turkish students by using drawings at different ages understanding of gene, DNA and chromosome concepts. Students from 8th, 9th, 11th grades and, science and biology student teachers were simply asked to draw the structure of gene, DNA and chromosome in a cell and also to give explanations about these three concepts. Differences in understanding between the age groups were found to be significant for the concepts of gene and DNA. None of the groups exhibit sound understanding and regardless of the age levels, students in all groups had alternative ideas about the three concepts investigated.     

Pedro Gutiérrez Bueno’s Textbooks: Audiences, Teaching Practices and Chemical Revolution

Pedro Gutiérrez Bueno wrote two editions of a chemistry textbook between 1788 and 1802. The paper offers a comparative view of both editions taking into account Gutiérrez Bueno’s biography, his intended audience and the changes related to the so-called chemical revolution. Some conclusions are at odds with common images about scientific revolutions and the role of textbooks in science. The analysis aims to shed some light on the multiple historical forces shaping textbooks and the way in which scientific change is assimilated by their writers.

县级中学高中生物理考试成败归因特点

以435名县级中学高中生为被试,以考试成败归因问卷为工具,旨在探讨高中生对物理考试成败结果的归因特点。研究表明:(1)整体上看,县级中学高中生对物理考试成败倾向于作内部归因,他们将持久努力、临时努力和学习方法等内部可控原因视为首要原因;(2)自我评价成功者与失败者对考试结果的归因存在明显差异;(3)男女生对考试成功的归因不存在明显的差异,对考试失败的归因有一定差异,女生比男生更看重能力、学习方法、学习基础与任务难度等原因对失败结果的影响;(4)高中生对考试成败的归因不存在明显的年级差异。     

Phonological awareness in kindergarten: a field study in Luxembourgish schools

The purpose of the present study was to assess the effectiveness of a phonological awareness training program in the specific context of the Luxembourgish educational system. The intervention was run by the kindergarten teachers in their classes with minimal external supervision. Forty-one classes of the area around Luxembourg City participated in the study. One hundred and fifty children from 20 kindergarten classes were part of the training group and 157 children from 21 classes formed the control group. At the end of kindergarten, clear training effects were observed for all phonological awareness tasks, except for the highly demanding phoneme deletion task. After 6 months of reading and writing instruction in first grade, no training effects were found in a pseudoword spelling task for the entire training group. Only at-risk children, which had the lowest performance on preschool phonological awareness measures, showed significant training effects. We conclude that early phonological awareness training may be profitably incorporated in kindergarten classroom activities, particularly for at-risk pupils, even when the language characteristics and teaching methods already concur in facilitating the understanding of the alphabetic principle.     

REA Presidential Address: Spaces of Inter-cultural Provocation for Religious Formation

In this essay, I reflect on the challenges faced by professors teaching Jewish studies in a Catholic university system. The essay records my experiences teaching two courses, “Judaism and the Holocaust” and “American Judaism: Thought and Culture,” at Santa Clara University as an adjunct lecturer during the academic year 1994‐95. The essay touches on broader questions concerning “the dialectics of difference” that inform cross‐cultural education and exchange. Teach‐ ing Jewish studies in any Gentile space (Catholic, Protestant, or secular) entails a constructive tension between trust and suspicion, candor and reserve.     

Envisioning a critical social pedagogy of learning and work in a contemporary culture of cyclical lifelong learning

In Canada, current federal learning-and-work policy is focused on individual learner-worker development using an iteration of lifelong learning as cyclical. This policy aims to enhance the social as an effect of enhancing the economic. In this neoliberal milieu, cyclical lifelong learning has become not only a norm but also a culture and an attitude. Still, a current Canadian phenomenon indicates that increasing numbers of young adults are disengaging from participation in such learning that the federal government considers being a preventive measure. In discussing their withdrawal from what might be perceived as cyclical lifelong learning for control, I consider a particularly challenging case: the predicament of young adults in the Canadian province of Newfoundland and Labrador. To help us think about adequately addressing the dislocation they experience in life and work, I offer a Freire-informed vision of a critical social pedagogy of learning and work. This pedagogy calls for re-engendering the social in lifelong learning by revitalizing critical social concerns with historical awareness, hope, possibility, ethics, justice, democratic vision, learner freedom, critique, and intervention.     

Teacher professional development through collaborative action research: impact on foreign English-language teaching and learning

In 2011 we, a group of English-as-a-foreign-language teachers at a secondary school in Argentina, decided to investigate our teaching practices through collaborative action research so as to improve our students’ learning opportunities and thus revitalise English-language teaching in our context. We implemented and evaluated the integration of content and language learning in our classrooms through the development of our own materials. The experience revealed a growth in professional development and how our motivation and autonomy influenced our students’ motivation and language development. In our attempt to disseminate our experience as a group, this report particularly focuses on the evaluation facets of our collaborative action research project so as to encourage other teachers and teacher-researchers to adopt collaborative action research to improve their own practices.     

Parent Involvement,Parental Depression,and Program Satisfaction Among Low-Income Parents Participating in a Two-Generation Early Childhood Education Program

Research Findings: This study simultaneously examined parental depression and parent involvement as predictors of satisfaction with an early childhood intervention program. Parents (N = 203) of Head Start children participated in this short-term longitudinal study. Measures of parent involvement and satisfaction assessed multiple dimensions of these constructs. Nearly 40% of low-income mothers reported being sometimes or chronically depressed over the course of 1 year of the Head Start program. Compared with mothers who were never depressed, those who were sometimes depressed reported less involvement in home- and school-based activities as well as fewer interactions with their child's teacher. Never depressed parents were more likely to be satisfied with their child's teacher compared with either group of depressed mothers. Higher levels of parent involvement and parent–teacher interaction predicted optimal satisfaction with Head Start services. Practice or Policy: Implications of results for practice are considered in terms of teacher training to recognize unique needs involved in working to establish a home–school connection with mothers experiencing depression. Strategies for building community partnerships to assist with mental health needs are discussed.     

The Use of Newspaper Articles as a Tool to Develop Critical Thinking in Science Classes

The aim of this research is to identify the difficulties experienced by secondary school students (aged 15–16) with the critical reading of newspaper articles with scientific content. Two newspaper critical reading activities in relation to the study of various scientific contents were designed and carried out in two schools (61 students in total), one with a student population from a medium to high social and economic bracket and the other with students from a medium to low social and economic bracket. These activities were designed taking into account the phases of the reading process: before, during and after reading. In order to analyse the difficulties ‘Elements of science critical reading’ were identified on the basis of the ‘Elements of reasoning’ of Paul and Elder and the categories proposed by Bartz C.R.I.T.I.C. questionnaire and a scale was drawn up. The results show that the activities designed were useful in helping students to read critically. We also rated very positively the instrument created to assess the students' answers: the scale based on the performance indicators of Paul and Elder. This instrument enabled us to detect the aspects of critical thinking where students have the most difficulties: identifying the writer's purpose and looking for evidence in a text. It was also shown that the stance taken in the articles also had an influence on the results.
