Having Fun Doing Math: Text Messages Promoting Parent Involvement Increased Student Learning

There is a consensus that family involvement is key to academic achievement. However, it is often difficult to keep parents involved, particularly when they lack the time or academic knowledge. The aim of this study is to evaluate the impact on achievement in mathematics among adolescent children when involving parents from low-income communities in the learning process. This involvement is achieved through activities that do not include any formal curricular content. A randomly selected group of parents was nudged, via text message (SMS), to complete short and simple weekly activities with their children. The teacher then connected these activities to the curricular content in class. The results reveal that, on average, the intervention increased the students’ math grade point average (GPA) by 0.488 standard deviations (p?相似文献   

A cross-cultural study on the influence of cultural values and teacher beliefs on university teachers’ information and communications technology acceptance

This study examined how cultural values and teacher beliefs influence Chinese and Spanish university teachers’ acceptance of ICTs by combining Hofstede’s cultural values theory with technology acceptance theories. Four hundred and twenty-five university teachers from China and 385 teachers from Spain participated in the study. The proposed research model was tested by using samples from both countries and the multigroup analyses were performed to test moderating effects of cultural variables. Results confirmed the validity of the model in both samples and the effects of cultural values on the adoption of ICTs, and significant differences were observed between the two samples.

Motor fitness and preschooler children obesity status

The aim of this study was to examine the association between motor fitness (MF) and obesity status in preschool children.

The sample comprised 467 children aged 3–6 years. Preschool children body mass index was classi?ed according to International Obesity Task Force and categorised into three levels, normal, overweight and obesity. Total physical activity was assessed by accelerometer and MF test was assessed through two MF tests 10 × 5m shuttle run test (SRT) and a 7 m jumping distance on 2 feet test (J2F). Low MF was considered for MF if SD above 1. A single variable with three categories was created: low MF medium MF and high MF.

The prevalence of normal weight, overweight and obesity was 67.6%, 22.7% and 9.7%, respectively. The prevalence of SD > 1 for SRT was 13.7% and 14.4% for J2F, for single variable was 19.2%. Multinomial logistic regression analysis showed that obese preschoolers were more likely six times classified as having low MF level than their non-overweight counterparts (OR: 6.4; IC: 1.3–36.6).

This study showed a considerable prevalence of overweight and obesity among preschoolers. Obesity has already been associated with lower MF. Further longitudinal studies are needed to con?rm this data.     

Towards system oriented innovation policy evaluation? Evidence from EU28 member states

Many years after the introduction of the innovation system concept in innovation policy design, it is still not clear whether innovation policy evaluation practices follow a system approach. Building on evaluation and innovation studies, this article develops the concept ‘system oriented innovation policy evaluation’ based on four attributes (coverage, perspective, temporality and expertise). The attributes are used as analytical devices for gathering extensive empirical evidence on the actual practices of EU28 member states. The findings show that few countries have developed a type of innovation policy evaluation that is system oriented. The advent of a system approach to innovation policy evaluation offers the opportunity of comprehensive, contextualized and evidence-based innovation policy-making. However, there are still serious obstacles as such an approach requires important knowledge and organisational capacities. Overcoming these obstacles would need more decided evaluation capacity-building at the national level.     

Blending versus whole word approaches in first grade remedial reading: Short-term and delayed effects on reading and spelling words

Twelve very poor readers in May of first grade, including four withdisabilities, were randomly assigned to one of two daily tutoring conditions designed to teach children to read regularly spelled short words by one of two methods: blending sounds to form words, or cumulative introduction of whole words. Both treatments included letter/sound correspondences and spelling words in the reading set. At the end of ten sessions, no differences were found between the treatment outcomes; however, delayed posttests one week later found differences favoring the blending treatment on reading and spelling instructional words, and on transfer to words composed of known letter sounds.     

En Confianza: Co-constructing Professional Strength and Voice With Latina Early Childhood Educators

It is well documented in the literature that early pre-K reading experiences prepare children for the benefits of formal literacy instruction in the later grades. This is particularly true for young children from nonmainstream backgrounds. The objective of this article is to share the findings of a 4-year qualitative study investigating the relationships forged and teaching ideologies constructed by Latino pre-K teachers via critical “storying” within a culturally responsive professional learning community. Findings suggest that as teachers learned to recognize, listen to, and learn from the personal/professional individual and collective life histories of each other, their teaching efficacy was enhanced increasing their ability to develop effective literacy instruction that was culturally and linguistically responsive to the needs of young children.     

Scaffolding group explanation and feedback with handheld technology: impact on students’ mathematics learning

Based on strong research literatures, we conjectured that social processing of feedback by cooperating in a small group setting—with social incentives to ask questions, give explanations and discuss disagreements—would increase learning. We compared group and individual feedback, using two technologies: (1) Technology-mediated, Peer-Assisted Learning (TechPALS), which uses wireless handheld technology to structure feedback in small groups as they solve fractions problems and (2) a popular desktop product, which provides feedback to individual students as they solve fractions problems individually. Three elementary schools participated in a randomized controlled experiment conducted in the 2007–2008 school year. Students in the TechPALS condition learned more than did the control group students, with effect sizes ranging from d = 0.14 to d = 0.44. Analysis of observational data confirmed that students in the TechPALS condition participated socially in questioning, explaining, and discussing disagreements, whereas students in the individual condition did not. We conclude that an integration of technology, cooperative activity designs and broader educational practices can lead to impact on students’ mathematics learning.     

Tweeting but not Talking: The Missing Element in Talk Radio's Institutional Use of Twitter

The interplay between Twitter and media organizations has been an increasing area of research. This article examines how talk radio stations have adopted Twitter at an institutional level, based on a comparative study of the official accounts of three prominent talk radio stations in Canada in 2010 and 2011. While talk radio is considered an interpersonal medium, our analysis shows the stations mainly use Twitter as a one-way medium to broadcast news updates, rather than to engage with audiences. Our findings suggest a divergence between institutional and individual social media practices, with official accounts as formal channels of communication.
