Increased parietal activity after training of interference control

Recent studies suggest that computerized cognitive training leads to improved performance in related but untrained tasks (i.e. transfer effects). However, most study designs prevent disentangling which of the task components are necessary for transfer. In the current study, we examined whether training on two variants of the adaptive dual n-back task would affect untrained task performance and the corresponding electrophysiological event-related potentials (ERPs). Forty three healthy young adults were trained for three weeks with a high or low interference training variant of the dual n-back task, or they were assigned to a passive control group. While n-back training with high interference led to partial improvements in the Attention Network Test (ANT), we did not find transfer to measures of working memory and fluid intelligence. ERP analysis in the n-back task and the ANT indicated overlapping processes in the P3 time range. Moreover, in the ANT, we detected increased parietal activity for the interference training group alone. In contrast, we did not find electrophysiological differences between the low interference training and the control group. These findings suggest that training on an interference control task leads to higher electrophysiological activity in the parietal cortex, which may be related to improvements in processing speed, attentional control, or both.

Assessment of anastomotic leakage: A Novel System for the Training of Surgeons to Perform a Tubular Anastomosis and Objectively Evaluate Anastomotic Leak

Introduction: Dehiscence of the suture line of an anastomosis can lead to reoperation, temporary or permanent stoma, and even sepsis or death. Few techniques for the laboratory training of tubular anastomosis use ex-vivo animal tissues. We describe a novel model that can be used in the laboratory for the training of anastomosis in tubular tissues and objectively assess any anastomotic leak. [See PDF for complete abstract]

Preservice, Secondary Social Studies Teachers' Perceptions of Gender Equity

This study examines preservice, social studies teachers’ perceptions of gender equity. The assumption that preservice teachers recognize gender as an important issue and are willing and able to take the initiative to remedy inequities in their classroom structures and content is considered. Six participants were interviewed using Seidman’s (2006) three-round, interview protocol. A focused life history was compiled to situate participants’ perceptions within their personal and professional experiences. Findings suggest a disconnect between preservice teachers' intentions and their practice in regards to gender equity. More explicit attention to gender equity in teacher education programs is recommended.

Prospective EFL (English as a Foreign Language) Teachers’ Perceptions of Learner Autonomy

This study investigated prospective EFL (English as a Foreign Language) teachers’ perceptions of learner autonomy. Main aim was to see whether the education they receive on how to teach English make any difference in prospective EFL teachers’ perceptions regarding learner autonomy. A researcher-developed questionnaire was administered to 179 students studying in the program of ‘Teaching English as a Foreign Language’ at Anadolu University in Turkey. Results of the study indicated that generally there is not much difference between the first and fourth year participants of the study in terms of their perceptions of learner autonomy.

Education and Training of Future Nuclear Engineers Through the use of an Interactive Plant Simulator

The successful experience of the Jose Cabrera Nuclear Power Plant Interactive Graphical Simulator implementation in the Nuclear Engineering Department in the Universidad Polite´cnica de Madrid, for the Education and Training of nuclear engineers is shown in this paper. The paper starts with the objectives and the description of the Simulator Aula, and the methodology of work following the recommendations of the IAEA for the use of nuclear reactor simulators for education. The practices and material prepared for the students, as well as the operational and accident situations simulated are provided.

Best practices for school leaders: Implementation of a profesional competence model for school management in Chile

In Chile, during the last three decades there has been a strong decentralization process whose main objective has been to improve the management of schools through the transfer of responsibilities and resources of education and thus improve the outcome of learning, reducing equity gaps between schools and territories. This is how, there has been an evolution of school principals¿ professional profile from an administrative to a management approach, in which principals have become project managers of educational projects. From a competence model for school leaders, based on IPMA guidelines, the present article presents an analysis of best practices for school management, allowing to generate a link between competencies and school management, from the perspective of project management. Results showed that the different competence elements, have relative weights according to the different practice fields, and that this analysis can be considered as a strategic element in educational project planning and development.

Carolyn Banner

Carolyn had a Bachelor of Science in Education degree from Langston University and a Master of Science degree in Early Childhood Development from the University of Minnesota. In 1959 Carolyn came to Lincoln as acting principal of the laboratory Elementary School and Supervisor of Elementary Student Teaching. She nurtured and taught hundreds of Lincoln’s students to be the finest, most qualified teachers in the country. Once retired she was able to enjoy the many awards that she received through out her years. The awards she received were citations, and honors: AAUW Woman of Achievement Award, and the MUATE Outstanding Teacher Educator Award. She was elected the first Black President of AAUW in 1965. She was appointed to the Mayor’s Census and Redistricting Committee in 1981. On June 21st, 1985 Mayor George Hartsfield declared that day as “Carolyn Banner Day” in Jefferson City. Carolyn Banner retired from Lincoln University in July 1985.

Coordination of aproximations in secondary school students’ understanding of limit concept

The aim of this research is to characterize the coordination of the processes of approximation related to the understanding of the limit of a function. We analyze the answers of 64 post-secondary school students to 7 problems considering the dynamic and metric conception of limit of a function. Results indicate that the metric understanding of the limit in terms of inequality supports that the student is capable of coordinating the approximations in the domain and in the range when lateral approximations coincide. However, the student is not capable of this coordination when lateral approximations do not coincide. This indicates that the metric understanding of the limit begins with the previous construction of the dynamic conception in case of coincidence of the lateral approximations in the range.
