Effective strategies for mental and written arithmetic calculation from the third to the fifth grade

The strategies used to solve mental and written multidigit arithmetical addition, subtraction, multiplication and division were observed in 200 third, fourth and fifth grade children. A strategy was classified as effective if it resulted in the correct solution at least 75% of the time. For mental addition and subtraction, primitive strategies such as counting on fingers and counting on (mental counting from a specific point), and the more sophisticated strategy 1010 (solution of the calculation problem using tens and units separately) were more effective than the strategies learned at school. In written addition, subtraction and multiplication there was a shift from the CAR+to the CAR- strategy (tabulating with, or without, a carried amount) from the third to the later grades. Results show that typical strategies taught at school progressively substitute every other strategy both in mental and written calculation, but without reaching the criterion of effectiveness. The implications for maths curricula are discussed.     

Written feedback provided by first-year engineering students,undergraduate teaching assistants,and educators on design project work

ABSTRACT

Feedback is an important part of design education. To better understand how feedback is provided to students on their engineering design work, we characterised and compared first-year engineering students’, undergraduate teaching assistants’, and educators’ written feedback on sample student design work. We created a coding scheme including two domains: Substance and Focus of feedback. Educators made more and longer comments than undergraduate teaching assistants, and undergraduate teaching assistants made more and longer comments than first-year students. The first-year students focused on giving specific directions in their feedback while educators and undergraduate teaching assistants asked thought-provoking questions. Students tended to make more comments about the ways that their peers had communicated their design work while educators and undergraduate teaching assistants made more comments about the design ideas presented in the sample work. This study offers implications for practice for supporting educators, undergraduate teaching assistants, and first-year engineering students to be able to provide feedback on design work.     

Is home visiting an effective strategy? A meta-analytic review of home visiting programs for families with young children

Home visiting programs for families with young children have been in effect for many years; however, this is the first comprehensive meta-analytic effort to quantify the usefulness of home visits as a strategy for helping families across a range of outcomes. Sixty home visiting programs contributed data to analysis within 5 child and 5 parent outcome groups. Standardized effect sizes were computed for each end-of-treatment outcome measure, for each treatment versus control contrast. Weighted mean standardized effect sizes ranged from -.043 to.318; 6 of the 10 significantly differed from 0. No one program characteristic consistently affected effect sizes across outcome groups. The extent to which these findings have practical use for the field is discussed.     

Healthy Families New York (HFNY) randomized trial: effects on early child abuse and neglect

OBJECTIVE: To evaluate the effects of a home visiting program modeled after Healthy Families America on parenting behaviors in the first 2 years of life. METHODS: A sample of 1173 families at risk for child abuse and neglect who met the criteria for Healthy Families New York (HFNY) was randomly assigned to either an intervention group that was offered HFNY or a control group that was given information and referrals to other services. Data were collected through a review of CPS records, and maternal interviews at baseline and the child's first birthday (90% re-interviewed) and second birthday (85% re-interviewed). RESULTS: HFNY mothers reported committing one-quarter as many acts of serious abuse at age 2 as control mothers (.01 versus .04, p<.05). Two sets of interactions were tested and found to have significant effects (p<.05). At age 2, young, first-time mothers in the HFNY group who were randomly assigned at 30 weeks of pregnancy or less were less likely than counterparts in the control group to engage in minor physical aggression in the past year (51% versus 70%) and harsh parenting in the past week (41% versus 62%). Among women who were "psychologically vulnerable," HFNY mothers were one-quarter as likely to report engaging in serious abuse and neglect as control mothers (5% versus 19%) at age 2. CONCLUSIONS: These findings suggest that who is offered home visitation may be an important factor in explaining the differential effectiveness of home visitation programs. Improved effects may be realized by prioritizing the populations served or by enhancing the model to meet program objectives for hard-to-serve families.     

Understanding the Gender Gap in Science and Engineering: Evidence from the Chilean College Admissions Tests

This study seeks to develop a better understanding of the underrepresentation of women in science and engineering by analyzing the gender gaps (a) in the interest in pursuing a science degree and (b) on science achievement. We use national-level college admissions data to examine gender differences and to explore the association between these outcomes and the attendance to single-sex or co-educational schools. The Chilean college admissions system provides a unique context to study these gender differences, since applicants who wish to pursue an undergraduate degree in science or engineering are required to take a high-stakes standardized science achievement test as part of the admission battery. This test has three subjects: biology, physics, and chemistry, and applicants must choose to be tested in only one of them. Significant gender differences exist for the examinees in their choice of subject and achievement on (the tests). Gender gaps favoring males are observed in the three forms. Both interest and achievement in science are associated with the sex composition of the school attended.     

The Development of Research Skills in Young Adults with Intellectual Disability in Participatory Research

There is limited information about specific research constructs developed by adults with intellectual disability in undertaking research despite increasing involvement in research with rather than on these individuals. Participatory research was used with three young adults with intellectual disability to collaboratively develop a training programme and investigate the skills used and developed when undertaking the research project. Three research domains—Knowledge, Conceptual understandings and Skills, were identified, within which 18 subsets were categorised. Development in all domains and subsets occurred for all young adults, with variations in gains across subsets and participants. These young adults attained research knowledge, understanding and skills that enabled them to become collaborative researchers within this project.     

Sustainability education: researching practice in primary schools

Many teachers are keen to implement sustainability education in primary schools but are lacking the confidence, skills and knowledge to do so. Teachers report that they do not understand the concept and cannot integrate sustainability into an already overcrowded curriculum. Identifying how teachers successfully integrate sustainability education into their teaching practice can offer important insights into how these perceived problems can be overcome. The paper is based on data from the third year of a longitudinal study about teacher education and teacher professional learning for sustainability in primary education. The third year of the study investigated teachers’ understandings of sustainability and how sustainability education is manifested in eight rural and regional primary schools in Victoria, Australia. Data included photographs of school grounds and sustainability projects, audio recordings of focus groups with teachers and principals, and field notes of meetings with school staff. Sustainability education was found to be an emergent practice necessarily constituted in the relation between teachers, students and community members and the materialities of local places. Partnerships were found to be an essential part of integrated sustainability programmes which extended into communities and places beyond the schools. The processes of learning involved pedagogies of creative problem-solving and inquiry learning that enabled children to lead the way.     

From Verona to Ramallah: Living in a State of Emergency

I have spent much of the last two years working in a school in Ramallah, Palestine, supporting new teachers of English. I worked in the classroom, in partnership, sharing the planning and teaching of lessons. This essay is about exploring what happens to texts in a specific classroom context, about how a particularly English text, Romeo and Juliet, was interrogated and remade by young people in a class I taught with Victoria, a young American in her first year of teaching, and about how the study of this fictive text enabled them to explore fundamental questions of identity and difference. Victoria and I, foreigners in Palestine, taught English and shared a common language with the students. This, and the technology available to us, might seem to promise easy communication but this is an illusion, for these things cannot transcend the differences between us – differences that are part of the human condition and have to be acknowledged and embraced if there is to be any meaningful dialogue between us. The essay is therefore also an exploration of the possibilities for communication between us, largely through the literature we read and about the insights we provide for each other in the course of our talk and activities about the text.     

Durable Research,Portable Findings: Rhetorical Methods in Case Study Research

ABSTRACT

Case studies have been a central methodology employed by scholars working in the rhetoric of science and technical communication. However, concerns have been raised about how cases are constructed and collected, and what they convey. The authors reflect on how rhetoricians of science and technical communication researchers can – and do – construct a variety of case-based mixed-methods studies in ways that may make our research more portable and durable without undercutting the important and central role of case-based analysis.     

The Role of Mindfulness,Self‐Compassion,and Emotion Regulation in Eating Disorder Symptoms Among College Students

Eating disorders often emerge, resurface, or worsen in individuals during college (National Eating Disorders Association, 2013), substantiating the need to identify protective factors. The relationship between mindfulness, self‐compassion, and emotion regulation and disordered eating was examined in a sample of 100 university students. Results of a path analysis indicated significant direct and indirect effects. Clinical implications and recommendations for future research are discussed.
