Improving Silent Reading Performance Through Feedback on Eye Movements: A Feasibility Study

This feasibility study investigated if feedback about individual eye movements, reflecting varying word processing stages, can improve reading performance. Twenty-five university students read 90 newspaper articles during 9 eye-tracking sessions. Training group participants (n = 12) were individually briefed before each session, which eye movement parameter(s) (fixation count, first fixation duration, regression, and/or skipping) to address, and informed about changes achieved in preceding sessions. Control group participants (n = 13) were told that self-instruction to read faster would produce training gains. Total fixation times decreased significantly more for training than for control group participants. Important to note, faster reading did not impair comprehension. Results are interpreted as first indications for a possible applicability of the feedback approach to silent reading. In addition to implications for future studies, alternative result interpretations (e.g., motivational effects, reduction of mindless reading) are discussed.     

Why extraversion is not enough: the mediating role of initial peer network centrality linking personality to long-term academic performance

Academic performance (i.e., grade point average) determines career entry factors as well as career success and is thus crucial for students’ future careers. Besides individual factors such as personality traits, individuals’ social embeddedness has been shown to enhance performance. Regarding academic performance, relationships to fellow students (peers), which bundle into one’s developmental network, are a valuable source of psychosocial and career support because occupying central positions within a social network provides the benefit of being able to access career-enhancing resources. Integrating individual and social-contextual factors for the purpose of examining academic performance is therefore plausible. Research results indicate that personality, especially extraversion, might predict performance through network centrality. In this study, we examined this assumption by focusing on extraversion and centrality in the peer developmental network of recently acquainted German psychology bachelor students (N?=?47, 15% male). In a longitudinal design, we analyzed the impact of extraversion and centrality on students’ academic performance at the end of their studies. Results revealed that centrality (i.e., popularity) mediates the relationship of extraversion with academic performance, indicating that extraverted students (regardless of their agreeableness) are more popular among their peers, which, in turn, enhances their academic performance. That is, the likelihood of getting superior final grades depends on whether students manage to attract peers at the very beginning of their university life, which is easier for extraverts. These findings emphasize the importance of the social embeddedness of people, highlight its long-term effects on performance, and yield several implications for research and practice.     

Navigation system for a smart wheelchair

Recent results on the development of a navigation system for a smart wheelchair are presented in this paper. In order to reduce the development cost, a modular solution is designed by using commercial and low cost devices. The functionalities of the tracking control system are described. Experimental results of the proposed assistive system are also presented and discussed.     

In vitro remineralization of hybrid layers using biomimetic analogs

Resin-dentin bond degradation is a major cause of restoration failures. The major aim of the current study was to evaluate the impact of a remineralization medium on collagen matrices of hybrid layers of three different adhesive resins using nanotechnology methods. Coronal dentin surfaces were prepared from freshly extracted premolars and bonded to composite resin using three adhesive resins (FluoroBond II, Xeno-III-Bond, and iBond). From each tooth, two central slabs were selected for the study. The slabs used as controls were immersed in a simulated body fluid (SBF). The experimental slabs were immersed in a Portland cement-based remineralization medium that contained two biomimetic analogs (biomineralization medium (BRM)). Eight slabs per group were retrieved after 1, 2, 3, and 4 months, respectively and immersed in Rhodamine B for 24 h. Confocal laser scanning microscopy was used to evaluate the permeability of hybrid layers to Rhodamine B. Data were analyzed by analysis of variance (ANOVA) and Tukey’s honest significant difference (HSD) tests. After four months, all BRM specimens exhibited a significantly smaller fluorescent area than SBF specimens, indicating a remineralization of the hybrid layer (P≤0.05). A clinically applicable biomimetic remineralization delivery system could potentially slow down bond degradation.     

The relationship among achievement goals,standardized test scores,and elementary students’ focus in school

The study examined whether an academic, social, or both an academic and social focus might relate with achievement goals and academic achievement. Participants were 412 urban elementary school students. Results suggest that students with an academic focus toward school have more mastery‐approach and less mastery‐avoid achievement goals. Academic achievement (standardized test scores) did not relate with boys’ or girls’ focus toward school. These findings suggest that academic motivation, but not achievement, correspond with self‐perceptions of school as being a place to learn or school as a place for social interactions.     

Advocacy for gender minority students: recommendations for school counsellors

Abstract

Research shows that teachers’ and educators’ responses to gender diversity issues in schools either improves or limits the experiences of students. The school counsellor has an important role to play in this process by working closely with other stakeholders to advocate for transgender, intersex and genderqueer (TIG) students. Following a review of recent developments in the USA, recommendations are made and resources identified to assist school counsellors in validating TIG students, and improving school systems in pursuit of their academic, social and emotional success.     

Adults' learning motivation: Expectancy of success,value, and the role of affective memories

The present study tested the applicability of expectancy-value theory to adults' learning motivation. Motivation was measured as the anticipated reaction (AR) of German students (N = 300) to receiving their instructions in English as a new learning opportunity. We used structural equation modeling to test our hypotheses. Expectancies of success and values from school predicted current expectancy and value, which, in turn, accounted for about 64% of variance in AR. In addition, we explicitly tested the hitherto neglected role of affective memories as a major precursor of value, expectancy of success, and AR. Results show a small direct effect of only negative affective memories on AR, leading to a significant incremental prediction of AR in addition to expectancy and value. Thus, motivation and experiences at secondary school appear to play a crucial role in adults' learning motivation, mediated by expectancy and value specific to the learning opportunity.     

Students’ educational use of Facebook groups

The aim of the article is to explore educational use of student-managed Facebook groups in upper secondary education (in Denmark). Much research on educational potentials of Facebook has studied groups managed by teachers. However, there is a lack of in-depth research on Facebook groups managed by students and without participation from teachers. As this study shows, students’ use of student-managed groups differs from their use of teacher-managed tools such as learning management systems (LMSs). The article presents an empirical study based partly on a content analysis of 3139 posts and 15,018 replies within five Facebook groups, and partly on a questionnaire answered by 1463 students and 148 teachers. The results of the study show that whereas LMSs were seen by students primarily as institutional systems of the teacher, Facebook groups have an educational potential to be used by students for peer-to-peer learning.
