The incidence and nature of letter orientation errors in reading disability

Letter orientation confusions (reversals) in the reading and writing of 10-year-old children with and without reading disability were investigated to determine whether reading disability is associated with letter orientation errors and to identify the nature of the errors. In a variety of tasks measuring letter orientation confusions in reception (reversal detection and recognition) and production (controlled writing, copying), individuals with reading disability made more orientation confusions than average readers. Orientation errors were more frequent for reversible than for nonreversible items in tasks involving long-term memory processes. The results did not appear to be related to group differences in attention or speed of motor responding. Possible sources of orientation confusions, including deficient magnocellular system processing, mislabeling, and overreliance on visual strategies, are discussed.     

Microfluidic electromanipulation with capacitive detection for the mechanical analysis of cells

The mechanical behavior of cells offers insight into many aspects of their properties. We propose an approach to the mechanical analysis of cells that uses a combination of electromanipulation for stimulus and capacitance for sensing. To demonstrate this approach, polystyrene spheres and yeast cells flowing in a 25 μm×100 μm microfluidic channel were detected by a perpendicular pair of gold thin film electrodes in the channel, spaced 25 μm apart. The presence of cells was detected by capacitance changes between the gold electrodes. The capacitance sensor was a resonant coaxial radio frequency cavity (2.3 GHz) coupled to the electrodes. The presence of yeast cells (Saccharomyces cerevisiae) and polystyrene spheres resulted in capacitance changes of approximately 10 and 100 attoFarad (aF), respectively, with an achieved capacitance resolution of less than 2 aF in a 30 Hz bandwidth. The resolution is better than previously reported in the literature, and the capacitance changes are in agreement with values estimated by finite element simulations. Yeast cells were trapped using dielectrophoretic forces by applying a 3 V signal at 1 MHz between the electrodes. After trapping, the cells were displaced using amplitude and frequency modulated voltages to produce modulated dielectrophoretic forces. Repetitive displacement and relaxation of these cells was observed using both capacitance and video microscopy.     

THE INTERPLAY BETWEEN ADOLESCENTS’ PERCEPTIONS OF TEACHER‐STUDENT RELATIONSHIPS AND THEIR ACADEMIC SELF‐REGULATION: DOES LIKING A SPECIFIC TEACHER MATTER?

Although positive teacher‐student relationships are known to aid students’ academic self‐regulation, the emotional aspects of teacher liking are often neglected within research. The present study used a large sample of seventh‐ and eighth‐grade students (N = 1,088; M_Age =  13.7) in secondary schools in Germany to investigate whether the motivation students gain from specific well‐liked teachers (i.e., that students identify) can moderate the relation between their perception of teacher‐student relationships overall and academic self‐regulation (intrinsic motivation, identified, introjected, and external regulation). By means of latent moderated structural equations, students’ motivation based on liking one specific teacher was found to moderate the association between teacher‐student relationships and intrinsic motivation. The present study makes a contribution to the existing research on teacher‐student relationships and academic self‐regulation by investigating the role of students’ motivation related to the liking of a specific teacher. Results indicate that when early adolescent students can identify a well‐liked teacher, they tend to have higher levels of academic motivation. Hence, students’ motivation based on liking a single teacher compensates for generally low‐quality teacher‐student relationships and their respective impact on students’ intrinsic motivation.     

THE POWER OF SOCIAL AND MOTIVATIONAL RELATIONSHIPS FOR TEST‐ANXIOUS ADOLESCENTS’ ACADEMIC SELF‐REGULATION

Based on cognitive evaluation theory (CET) and organismic integration theory (OIT) – both sub‐theories of self‐determination theory (SDT) – the present study examined whether the academic self‐regulation of youth with test anxiety can be strengthened through social and motivational relationships with peers and teachers. This study employed a large sample (N = 1088; MAge = 13.7) of early adolescents from secondary schools in Brandenburg, Germany. Structural equation modeling (SEM) was used to test the proposed associations. The results revealed a negative association between test anxiety and intrinsic motivation as well as test anxiety and identified regulation, which was fully mediated by teachers as positive motivators. Furthermore, both teachers as positive motivators as well as the teacher‐student relationship were found to be strong predictors of the self‐determined aspects of academic self‐regulation. Additionally, both peers as positive motivators and the student‐student relationship are essential for external self‐regulation.     

Brief Therapy at a University Counseling Center: Working Alliance,Readiness to Change,and Symptom Severity

The authors investigated whether students receiving short–term individual counseling at a university counseling center showed progress as evidenced by perceived client and counselor outcomes and the roles that client readiness to change and working alliance played in this setting. The results indicated that the counselor reports, not the client reports, reflected statistically significant change in client symptoms. Changes in symptom severity were not associated with working alliance and readiness to change.     

New practices in doing academic development: Twitter as an informal learning space

Using social media platforms to build informal learning processes and social networks is significant in academic development practices within higher education. We present three vignettes illustrating academic practices occurring on Twitter to show that using social media is beneficial for building networks of academics, locally and globally, enhancing information flows, inspiring thinking, and motivating academic practice. Using a reflective and diffractive methodology, we illuminate how different flows of forces and relations are enacted. We argue it is in this fluidity of informal learning that perspectives are contested and shaped, and that academic developers can benefit by encompassing such practices.     

Negotiating the challenge of collaborative writing: learning from one writing group's mutiny

With continuing pressure to publish or perish, interventions such as writing groups are increasingly part of the academic landscape. In this paper, we discuss our writing group's experiment with collaborative writing, which came unstuck as simmering concerns led to a mutiny within the group. The mutiny provided insights into tensions that are inevitably present in writing groups and collaborative writing exercises but are seldom written about. We explore these tensions via a collaborative autoethnography, drawing on published literature on writing groups and collaborative writing. The mutiny revealed three key dynamics. Experienced voices can have an important role to play but these voices need to be moderated so that other voices might be recognised and valued. Pleasure and productivity are two necessary components for sustaining writing groups and writing collaborations. Finally, hierarchies in the academic context are inescapable but they can be renegotiated so that more enabling power relations can be generated.     

Challenges in Enacting Core Practices in Language Teacher Education: A Self-Study

In this study, I explore my practices as a teacher educator in one course both before and after returning to the K–12 classroom to teach secondary language learners for one academic year. By examining the intersection of self-study and practice-based teacher education, I illustrate how I used self-study as a mechanism for innovation and change and focus on the challenges I encountered in implementing the use of practice-based education in my work as a teacher educator. Qualitative data analysis revealed that in redesigning my approach to my course, I stopped short of my goals to make the course more practice-centered. Although I provided students with many opportunities to practice planning, I did not provide enough focused opportunities to practice implementation and to participate in giving and receiving feedback. I learned that engaging teachers in practice-based teaching requires teacher educators to be both specific and deliberate in setting their own purposes for establishing the centrality of practice in their courses and to explain these clearly to teacher candidates. Further work in which teacher educators study their use of practice-based pedagogy would benefit from using a self-study lens. Other researchers are urged to add to the limited body of research about the use of practice-based pedagogy with teachers of language learners, particularly English language learners.
