A first grade student’s exploration of variable and variable notation / Una alumna de primer grado explora las variables y su notación

Abstract

This paper presents a case study of a first grade student to illustrate the diversity of her understandings related to variables and variable notation. While prior research has documented secondary school students’ difficulties with variables and variable notation, we identify many productive understandings in this much younger student, leading us to question the prevailing argument that students might have difficulties with variables due mostly to their own limitations. We draw our data from a teaching experiment that explored functional relationships. Individual interviews were carried out with a subset of the students in the experiment prior to, as well as mid-way through and at the end of the experiment. This paper focuses on a set of three interviews with one of the first grade students. We illustrate the shifts that occurred in the student’s understandings about variables and variable notation across as well as within each of the three interviews.     

2～3.5岁儿童执行功能发展特点及其言语能力的影响

2~3.5岁是婴儿成长到幼儿的重要发展转折期,也是儿童执行功能及言语能力的发展萌芽期。研究通过测查北京市81名2~3.5岁儿童在固定盒子任务、搭积木任务、A非B任务和皮博迪图片词汇测验上的表现,探究了该年龄段儿童执行功能的发展特点、各成分间的内部关系、以及言语能力对执行功能的影响。结果发现:(1)在2~3.5岁期间,除认知灵活性外,儿童的工作记忆与抑制控制均快速发展,其中,2.5岁前后是工作记忆与抑制控制的重要发展时期;(2)在2~3岁期间,认知灵活性与工作记忆之间相关密切,在3~3.5岁期间,认知灵活性与抑制控制的相关密切,3岁是儿童执行功能内部成分关系的重要发展转折期;(3)在2~3.5岁期间,儿童言语能力呈现快速发展,并且言语能力对该年龄段执行功能各成分间关系产生一定的影响,但不同言语能力的儿童在执行功能各成分的表现并没有显著差异。     

幼儿父母婚姻冲突与教养方式的关系:父母情绪调节策略的调节作用

以285名幼儿家长为被试,采用问卷法考察婚姻冲突对权威教养和专制教养的差别效应以及父母情绪调节策略在其中的调节作用。结果发现:(1)幼儿父母的婚姻冲突能显著负向预测其权威教养,显著正向预测其专制教养,婚姻冲突对两类教养的预测作用大小无显著差异;(2)父母情绪调节策略对婚姻冲突与权威教养关系的调节作用显著,且这种调节作用不存在家长性别的差异:较少使用认知重评或较多使用表达抑制的家长,其婚姻冲突能显著负向预测权威教养;经常使用认知重评或较少使用表达抑制的家长,其婚姻冲突对权威教养的影响不显著。父母情绪调节策略对婚姻冲突与专制教养关系的调节作用不显著。     

Angels: a bridge to a spiritual pedagogy?

This article is the result of an Early Childhood Care and Education undergraduate pilot project through a university on the West Coast of Canada. It weaves together poststructural interpretations and a hermeneutic phenomenological recounting of an experience of inquiring about angels with young children. The angel inquiry became a point of entry into a holistic spiritual pedagogy that attends to the whole of a matter, while also paying attention to the significance of each part. Contributing to the interpretations made in this study is Ted Aoki’s philosophy of the space between where the planned curriculum and the lived curriculum (or lived experiences) meet in a third and overlapping tensional space; Max van Manen’s emphasis on lived experiences as ‘breathing meaning’ also contribute to the choices and interpretations made. Blended through the study are the understandings of Tobin Hart and Kate Adams from their investigations of children’s lived experiences with mystical unseen worlds. The area of invisible mystery proves to be more delicate to negotiate than the world of physical embodiments and the world of complete fantasy of the mind; this is the area of the spiritual – the meeting of body and mind with a third and overlapping space. This space goes by many names and many definitions, but ultimately remains indefinable and intangible. But during the pilot project, meaning did come through the inquiring and through the themes that emerged of ‘who we are’ in relation to angels; race, gender and the role of nurturer; and familial angel ownership. Children yearn for allowing spaces to safely express these ideas about, and experiences with, mystery worlds. It is the connection with the inner life through small moments and engagements with the big life questions that the entangling of the physical, the mental and the spiritual creates the intuitive, integrated heart space of a holistic spiritual pedagogy.     

Spirituality and spiritual care – missing concepts from core undergraduate children’s nursing textbooks

Background: Spiritual care is espoused to be fundamental in children’s nursing; however, the extent to which current fundamental children’s nursing textbooks support and advocate spiritual care delivery by children’s nurses and nursing students is unknown. Aim and objectives: To examine whether or not fundamental undergraduate children’s nursing textbooks include spiritual care content. Methods: Five hundred and nineteen books were sampled from the Nursing and Midwifery Core Collection list (UK) using a survey, the Spirituality Textbook Analysis Tool (STAT) to collect data. Analysis and Results: 519 books were included in the study using the STAT and 13 books included content on children’s spirituality. There were a variety of textbooks in the audit of those that made reference to the search terms in the STAT, it was found that content mainly addressed only two areas; religious faiths and the dying child. Recommendations: Children’s nurses require education about children’s spiritual developmental stage and age appropriate spiritual assessment. A lack of detailed information in core children’s nursing textbooks means that this area of nursing practice may be taught as an adjunct to care and not as an element of holistic care which is the gold standard that children’s nurses should strive for.     

Children’s prayers from a Hospital Chapel

Children’s prayers, from prayer books left in the Chapel of a Children’s Hospital between 1998 and 2002, were studied for what the children’s God-talk would reveal about their perceptions of God. Of the 3893 prayers written during this period, 346 were confidently identified as being authored by children. The sample of 346 prayers, which gave rise to 558 expressions of prayer, was explored through a content analysis, used quantitatively to summarise and describe the data, and a thematic analysis, informed by methods from Grounded Theory. The psychological and spiritual significance of the prayers is drawn out, demonstrating the richness and relationality of children’s spirituality. The predominance of prayers written by female writers, suggests that the extent to which relationality is present is related to gender. Questions concerning possible gender-related differences in girls’ and boys’ spirituality are raised and implications for practice are considered.     

Cultural adaptation of preschool PATHS (Promoting Alternative Thinking Strategies) curriculum for Pakistani children

Cultural adaptation of evidence‐based programmes has gained importance primarily owing to its perceived impact on the established effectiveness of a programme. To date, many researchers have proposed different frameworks for systematic adaptation process. This article presents the cultural adaptation of preschool Promoting Alternative Thinking Strategies (PATHS) curriculum for Pakistani children using the heuristic framework of adaptation (Barrera & Castro, 2006). The study was completed in four steps: information gathering, preliminary adaptation design, preliminary adaptation test and adaptation refinement. Feedbacks on programme content suggested universality of the core programme components. Suggested changes were mostly surface structure: language, presentation of materials, conceptual equivalence of concepts, training needs of implementation staff and frequency of programme delivery. In‐depth analysis was done to acquire cultural equivalence. Pilot testing of the outcome measures showed strong internal consistency. The results were further discussed with reference to similar work undertaken in other cultures.     

Understanding and Improving the Validity of Self-Report of Parenting

Although researchers using parental self-report data have questioned its validity (Holden, 2001) and called for more work in this area (Krevans & Gibbs, 1996; Locke & Prinz, 2002), methodological concerns regarding self-report about parenting practices have not been addressed adequately. The susceptibility of parental report to systematic distortions suggests a need for research on ways to improve self-report. This paper attempts to synthesize research findings from other fields (e.g., survey methodology) about ways to improve the validity of self-report, and to discuss the implications for self-report of parenting behaviors. Methods for improving self-report are presented for each of the 5 major tasks in responding to a question: (1) understanding the question, (2) recalling relevant behavior, (3) inference and estimation, (4) mapping the answer onto the response format, and (5) “editing” the answer for reasons of social desirability. Self-administered interviewing, audio-computer-assisted interviewing, pretesting, conversational interviewing, and the decompositional item may be among the best candidates for use in parental self-report. Recommendations are offered with respect to strategies that might prove useful in improving parental assessment of parenting, and to research efforts to evaluate the utility and potential costs of these strategies.     

Preschoolers' use of surface similarity in object comparisons: taking context into account

Previous research has emphasized the role of within-match similarity in children's comparisons. The current study investigated another potentially important contributing factor, namely the distinctiveness of the matching items relative to other items in the scene. Using a well-known relational mapping task, we found that 3- and 4-year-olds made more correct matches between identical objects when those objects were maximally distinctive from the foils. In a cross-mapping experiment, where same relative size was pitted against object similarity, 3-year-olds made more incorrect object matches when the objects were both similar to each other and distinctive from the foils. Furthermore, 3- and 4-year-olds performed the same, regardless of within-match similarity, so long as the ratios of within-match and nonmatch similarity were roughly equal. These findings suggest that children's comparisons are guided by a ratio consisting of many pairwise similarity relations, including (but not limited to) the degree of within-match similarity.     

Children of divorce in a Scandinavian welfare state: Are they less affected than US children?

A fairly common view holds that children's risks of negative outcomes associated with family dissolution are generally small or even nonexistent in Scandinavia, and clearly smaller than what is usually found in the United States. This view was empirically examined in a recent large-scale study of 4,127 12–15-year-old children in Norway, of whom 623 had experienced parental divorce and lived in a single-mother family. The somewhat paradoxical pattern of findings was as follows: (a) The negative associations between parental divorce and various outcomes were found to be generally very similar in Norway and the United States in spite of the great differences in family policy and welfare benefits for single mothers (at the macro level); and (b) Mediational effects of family economic resources were in both countries most marked for the academic achievement area, and the predictive power of such variables was quite similar, again in spite of the great differences in absolute level of the economic resources available to single-mother families in the two countries. The results cast some doubt on the value of the absolute economic deprivation perspective in explaining the results, and the many Norwegian welfare benefits do not seem to mitigate the association between divorce and negative outcomes for the children involved. Also policy implications derived from the economic deprivation perspective are questioned. Alternative interpretations of the findings involving relative deprivation and economic resources as a partial proxy for other non-economic factors are briefly discussed.
