Writing fluency and quality in kindergarten and first grade: the role of attention,reading, transcription,and oral language

In the present study, we examined the influence of kindergarten component skills on writing outcomes, both concurrently and longitudinally to first grade. Using data from 265 students, we investigated a model of writing development including attention regulation along with students’ reading, spelling, handwriting fluency, and oral language component skills. Results from structural equation modeling demonstrated that a model including attention was better fitting than a model with only language and literacy factors. Attention, a higher-order literacy factor related to reading and spelling proficiency, and automaticity in letter-writing were uniquely and positively related to compositional fluency in kindergarten. Attention and higher-order literacy factor were predictive of both composition quality and fluency in first grade, while oral language showed unique relations with first grade writing quality. Implications for writing development and instruction are discussed.

Predicting achievement of first semester university science students

This paper reports on 11 measures used as predictors of students' achievement in their first semester subjects. The students were enrolled in the same four core subjects of a university general science course. Although a number of statistically significant correlations were found, only one predictor variable, HSC aggregate mark, correlated significantly with each of the achievement variables. One predictor variable entered four of the achievement regression equations, while two variables entered the fifth, accounting for 34 to 54% of the variance. *** DIRECT SUPPORT *** A05A9011 00020     

Teaching Teamwork: Electronics Instruction in a Collaborative Environment

ABSTRACT

The Teaching Teamwork Project is using an online simulated electronic circuit, running on multiple computers, to assess students’ abilities to work together as a team. We pose problems that must be tackled collaboratively, and log students’ actions as they attempt to solve them. Team members are isolated from one another and can communicate only through an online chat channel, but modifications to the circuit made by any team member, insofar as they alter the behavior of the circuit, can affect measurements made by the others. We log all relevant student actions, including calculations (using an online calculator), measurements (using an online multimeter), inter-student communications, and alterations made by the students to the circuit itself. Automated analysis of the resulting data sheds light on the problem-solving strategy of each team, sometimes with surprising results.     

The body donation program at the Federal University of Health Sciences of Porto Alegre: A successful experience in Brazil

The use of dissection to study human anatomy is the foundation for educational excellence among future health professionals, as it offers an ideal opportunity to learn the body's morphology in three dimensions while also providing students with a more humanistic education. The shortage of bodies for dissection, combined with the Brazilian population's lack of knowledge concerning the possibility of voluntarily donating their own bodies, led to the creation of the Body Donation Programs for Education and Research in Anatomy at the Federal University of Health Sciences of Porto Alegre (UFCSPA). The program is based on three pillars: Informing the general public about the program, donor registration, and donation itself. Since the creation of the donor program in 2008, there has been an increase in both the number of donations made during donor's lifetime and the number of bodies received by the university. There has also been a shift in relation to the origin of these bodies, as before the creation of the program most bodies were unclaimed cadavers, while today most of the bodies are sourced from voluntary donations. The initial results regarding the public's acceptance of the possibility of making body donations have been encouraging, as shown by the annual growth in donor registrations. Consequently, the quality and quantity of the material available for educational purposes have greatly improved. Anat Sci Educ. © 2013 American Association of Anatomists.     

A Remediation Program in an Urban College

Abstract

This article presents ten strategies instructors can use to get their students to take more responsibility for their learning. Suggestions are given about the importance of getting students to verbalize why they are taking the course, helping students get into the proper mindset for each class, and structuring assignments so students will be more likely to come to class prepared. Other suggestions include teaching students to look out for each other, behave responsibly when working in groups, and analyze their learning experiences. By teaching responsibility, as well as content, in our classrooms, we can enhance learning, raise the level of our classrooms, and produce more responsible members of society.     

Relations among student attention behaviors, teacher practices, and beginning word reading skill

The role of student attention for predicting kindergarten word reading was investigated among 432 students. Using Strengths and Weaknesses of ADHD Symptoms and Normal Behavior Rating Scale behavior rating scores, the authors conducted an exploratory factor analysis, which yielded three distinct factors that reflected selective attention. In this study, the authors focused on the role of one of these factors, which they labeled attention-memory, for predicting reading performance. Teacher ratings of attention-memory predicted word reading above and beyond the contribution of phonological awareness and vocabulary knowledge. In addition, the relations between four teacher practices and attention ratings for predicting reading performance were examined. Using hierarchical linear modeling, the authors found significant interactions between student attention and teacher practices observed during literacy instruction. In general, as ratings of attention improved, better kindergarten word reading performance was associated with high levels of classroom behavior management. However, better word reading performance was not associated with high levels of teacher task orienting. A significant three-way interaction was also found among attention, individualized instruction, and teacher task redirections. The role of regulating kindergarten student attention to support beginning word reading skill development is discussed.     

Work–family relations among mothers of children with learning disorders

The study examined conflict and facilitation in work–family relations among working mothers of children with learning disorders (LD) or with typical development. The study also focused on three maternal personal resources (maternal anxious/avoidant attachment security, affect and sense of coherence) as antecedents of these work–family relations, and examined outcomes of such conflict and facilitation between the two life domains, as they affected patterns of close relationships within the family (child attachment and family cohesion). The sample included 96 mother–child dyads: 48 mothers and their children with LD; and 48 mothers and their typically developing children. Children’s ages were 8–12 years. All attended public elementary schools in urban areas of central Israel. Significant group differences emerged on mothers’ family to work conflict and on mothers’ work to family facilitation. Findings indicated that several maternal personal resources were antecedents of these relations and also contributed to differences in mother–child attachment relationships and family cohesion. Discussion focused on understanding work–family relations among these mothers of children with LD, as well as the influence of maternal personal resources on patterns of close relationships (i.e., child attachment, family cohesion).
