Causal Connections Between Mathematical Language and Mathematical Knowledge: A Dialogic Reading Intervention

The acquisition of early mathematical knowledge is critical for successful long-term academic development. Mathematical language is one of the strongest predictors of children's early mathematical success. Findings from previous studies have provided correlational evidence supporting the importance of mathematical language to the development of children's mathematics skills, but there is limited causal evidence supporting this link. To address this research gap, 47 Head Start children were randomly assigned to a mathematical language intervention group or a business-as-usual group. Over the course of eight weeks, interventionists implemented a dialogic reading intervention focused on quantitative and spatial mathematical language. At posttest, students in the intervention group significantly outperformed the students in the comparison group not only on a mathematical language assessment, but on a mathematical knowledge assessment as well. These findings indicate that increasing children's exposure to mathematical language can positively affect their general mathematics skills. This study is an important first step in providing causal evidence of the importance of early mathematical language for children's general mathematical knowledge and the potential for mathematical language interventions to increase children's overall mathematics abilities.     

The use of engineering design scenarios to assess student knowledge of global,societal, economic,and environmental contexts

Product archaeology as an educational approach asks engineering students to consider and explore the broader societal and global impacts of a product's manufacturing, distribution, use, and disposal on people, economics, and the environment. This study examined the impact of product archaeology in a project-based engineering design course on student attitudes and perceptions about engineering and abilities to extend and refine knowledge about broader contexts. Two design scenarios were created: one related to dental hygiene and one related to vaccination delivery. Design scenarios were used to (1) assess knowledge of broader contexts, and (2) test variability of student responses across different contextual situations. Results from pre- to post-surveying revealed improved student perceptions of knowledge of broader contexts. Significant differences were observed between the two design scenarios. The findings support the assumption that different design scenarios elicit consideration of different contexts and design scenarios can be constructed to target specific contextual considerations.     

Restorying as political action: authoring resistance through youth media arts

ABSTRACT

This article explores the lived realities for young people growing up and learning in a climate of racial discrimination, religious intolerance, misogyny, and xenophobia, and how school-sponsored and school-supported uses of digital media can afford young people opportunities to navigate their experiences of social injustice and resist exclusionary discourses and practices. In a collaborative inquiry into the practices of two youth media producers, we explore how these counternarrative efforts are forms of restorying, in which young people write themselves into existence in ways that can reconfigure school spaces. Framed in Black feminist and critical cosmopolitan perspectives, this article considers how young people use new media tools in school to engage the narrative imagination and build the worlds they want to live in, simultaneously representing the political histories and realities of their everyday worlds and imagining alternative futures. We explore the ways schools can create opportunities for youth to engage in these new media practices that re-author themselves and the institutional spaces they encounter – and how these opportunities are situated within broader intersectional forms of systemic inequity and oppression.     

“I'm just not that great at science”: Science self-efficacy in arts and communication students

Research in science education confirms the importance of self-efficacy in students' persistence and success in the sciences. The current study examined the role of science self-efficacy in nonspecialist, arts and communication-oriented students encountering science in a general education context. Participants (N = 275) completed a beginning- and end-of-semester survey including a Science Self-Efficacy Scale, a “connection to science” measure—the Inclusion of Science in Self Scale—and a Science Anxiety Scale. Participants also responded to two open-ended “sources of science efficacy” questions, and provided background/demographic information and access to their academic records. Results showed a significant increase in science self-efficacy and connection to science—although no change in science anxiety—over the course of the semester. The observed shift in self-efficacy for minority and international students was of particular note. These students started the course with lower confidence but, by the end of the semester, reported comparable science self-efficacy, and achieved similar grades to their White/Non-Hispanic and US resident classmates. Contrary to expectations, science self-efficacy did not predict performance in the class. However, students' self-reported sources of efficacy indicated increased confidence in using science in daily life, and confirmed the value of mastery experiences and of personally meaningful, student-centered course design in scaffolding student confidence. Results are discussed in terms of the individual and instructional factors that support science self-efficacy and student success in this unique, general education science environment.     

Increasing tootling: The effects of a peer‐monitored group contingency program on students' reports of peers' prosocial behaviors

In most educational ecologies, attention and consequences are focused on inappropriate behavior. Often students observe and report peers' antisocial behavior (i.e., tattle) and teachers investigate and consequent (i.e., punish) those behaviors. In the current study, a withdrawal design was used to investigate a corollary system. Fourth‐grade students were trained to observe and report peers' prosocial behaviors (i.e., tootle), and interdependent group contingencies and public posting were used to reinforce those reports. Although the first intervention phase showed much variability, subsequent phases showed that an intervention composed of public posting and interdependent group contingencies increased prosocial behavior reports. Results are discussed in terms of using this system to increase student and teacher awareness of and reinforcement for incidental prosocial behaviors. © 2000 John Wiley & Sons, Inc.     

Competency beliefs,positive affect,and gender stereotypes of elementary students and their parents about science versus other school subjects

Iowa students and parents completed related attitude and belief questionnaires about school subjects. Grade K–3 students received simpler questionnaires than did Grade 4–6 students or parents. Among Grade 4–6 children, girls perceived higher competence in reading than did boys, but boys perceived higher competence in physical science. All children perceived physical science competence lower than reading or math competence. Parents perceived boys as more competent in science. Girls like reading more than boys did; boys and girls did not differ in liking of science. Grade 4–6 children also expected lower grades in and attached lower importance to physical science than to reading. Parents perceived science as more important for boys and expected higher performance of boys. Jobs related to math or science were seen as more male dominated. These results provided a more comprehensive picture of attitudes and beliefs about science in the elementary school than had existed and suggested that attitudinal gender differences related to physical science begin to develop by the earliest elementary school years. Policy implications are that intervention programs designed to promote gender equity should be extended to the early elementary school years and also should address parental attitudes. Additional implications for policy and research are discussed. © 1999 John Wiley & Sons, Inc. J Res Sci Teach 36: 719–747, 1999     

First,Do No Harm: How Routine Interventions,Common Restrictions,and the Organization of Our Health-Care System Affect the Health of Mothers and Newborns

In this column, the author reprises recent selections from the Lamaze International research blog, Science & Sensibility. Each selection discusses a new study that demonstrates the “First, do no harm” principle in a different way. New research on the potentially harmful effects of intravenous lines demonstrates that refraining from routine interventions in labor protects the safety of women and babies. A new systematic review of movement and position changes in labor shows that eliminating unfounded restrictions also protects maternal and infant health and well-being. Finally, a study of patterns of use of neonatal intensive care units reveals how the organization of the maternity care system itself can affect the health outcomes of its beneficiaries.     

Cognitive and Neural Development of Individuated Self-Representation in Children

Processing the self-relevance of information facilitates recall. Similarly, processing close-other-related information facilitates recall to a lesser degree than processing self-relevant information. This memory advantage may be viewed as an index of the degree to which the representation of self is differentiated from representations of close others. To test developmental hypotheses concerning the self, this study examined the relation of memory for self- and mother-referentially processed information in participants age 7–13 years (Experiment 1: N  = 37; Experiment 2: N  = 14). Memory for words encoded with reference to oneself increases with age, relative to memory for words encoded with reference to one's mother. When used as an individual difference measure, the difference in self versus mother memory correlates with regions of the rostral anterior cingulate associated with affective salience.     

Concepts of scale held by students with visual impairment

This study investigated students' with visual impairment concepts about linear size and scale. Specifically the study examined the accuracy of students' concepts over many orders of magnitude as well as experiences students have had in and out‐of‐school learning about size and scale. The results of assessments of 17 students with visual impairment were compared to those of students with normal sight. The study showed that students with visual impairment were most accurate for measurements in the human scale and were least accurate with very large and very small scales that cannot be directly experienced. However, when compared to students with normal sight, students with visual impairment were more accurate at large and small scales than their normally sighted peers. © 2009 Wiley Periodicals, Inc.
