Language Intervention in Early Childhood

Developments in early intervention have paralleled those in early language intervention. Such parallels are not surprising given that general early childhood special education and language intervention practices have been influenced by the same theories of development and learning. In addition, because of the importance of communication to learning and academic achievement, and the prevalence of communication problems in children with special needs, language intervention has been fundamental to early intervention services and, reciprocally, language intervention practices have been challenged as a result of changes in early childhood services. In light of this relationship, this paper provides a focus on developments in language intervention within a framework of early intervention.

Differential effects of reading trainings on reading processes: a comparison in Grade 2

Phonics, fluency, and reading strategy trainings are evidence-based interventions that foster the reading skills of poor readers in primary school. The purpose of the present study was to compare differential effects of the three types of trainings on the efficiency of component processes on word, sentence, and text level immediately after the training and at a 3-month follow-up. The 235 poor readers were randomly allocated to one of the reading interventions or to a control condition. All interventions consisted of 25 sessions that were scheduled twice a week and lasted 45 min. Results indicated short-term effects of the phonics training and the strategy training on the efficiency of a broad range of word-level and sentence-level processes. None of the treatment effects persisted over the long term, indicating the need for instructional efforts to regularly practice the acquired skills after the actual training.     

Analyzing the temporal evolution of students’ behaviors in open-ended learning environments

Metacognition and self-regulation are important for developing effective learning in the classroom and beyond, but novice learners often lack effective metacognitive and self-regulatory skills. However, researchers have demonstrated that metacognitive processes can be developed through practice and appropriate scaffolding. Betty’s Brain, an open-ended computer-based learning environment, helps students practice their cognitive skills and develop related metacognitive strategies as they learn science topics. In this paper, we analyze students’ activity sequences in a study that compared different categories of adaptive scaffolding in Betty’s Brain. The analysis techniques for measuring students’ cognitive and metacognitive processes extend our previous work on using sequence mining methods to discover students’ frequently-used behavior patterns by (i) developing a systematic approach for interpreting derived behavior patterns using a cognitive/metacognitive task model and (ii) analyzing the evolution of students’ frequent behavior patterns over time. Our results show that it is possible to identify students’ learning behaviors and analyze their evolution as they work in the Betty’s Brain environment. Further, the results illustrate that changes in student behavior were generally consistent with the scaffolding provided, suggesting that these metacognitive strategies can be taught to middle school students in computer-based learning environments.     

Tennessee Promise: A Response to Organizational Change

Community colleges in Tennessee, either directly or indirectly, experienced unprecedented change as a result of Tennessee Promise. The present study explored how student support service administrators at three community colleges responded to organizational change as a result of the Tennessee Promise legislation. Investigators selected community colleges for the multi-site case study because the legislative impact would be actualized by the preparations made to serve incoming Promise recipients. The delivery of orientation services framed organizational change because the service staff facilitate connections and provide information to incoming students. Challenges like a shifting population, ill-equipped infrastructure, inadequate remediation support, heightened interest for social engagement opportunities, misinformation, and unmet fiscal needs left administrators seeking coherence through the change process. Investigators found community college administrators react to change similarly. Administrators acknowledged change as continuous, created a culture of innovation among stakeholders, and were not afraid to fail as responses to the organizational change phenomenon.     

Conceptions of teaching and educational knowledge requirements

Abstract

This paper scrutinises the educational knowledge requirements of craft, technical, and reflective professional conceptions of teaching, as recently outlined by Winch, Oancea, and Orchard. Drawing on Bernsteinian sociology of knowledge we identify the different requirements each conception makes of educational knowledge, and how it is envisaged that this knowledge will be used in educational practice. While craft conceptions dismiss the value of educational knowledge per se, they nevertheless value other forms of disciplined knowledge. Arguing that technical conceptions of teaching may be either narrowly instrumental or autonomous, we suggest that an advanced technical knowledge base requires a disciplinary aspect, while knowledge for purely instrumental purposes offers a reductive view of educational practice. Moreover, the varying notions of reflection suggested by reflective professional conceptions require certain forms of engagement with educational knowledge, which are challenged by contemporary reforms in teacher education globally. It is suggested that there are often interdependencies between forms of educational knowledge and conceptions of teaching, with potential implications for the trajectories of educational reforms. The argument is briefly illustrated with reference to the national contexts of Germany, England, and Finland.     

Nothing to Fear? An Analysis of College Students' Fear Experiences With Video Games

This study presents the results of a survey of 269 undergraduate students conducted to examine fright experiences caused by video games. Over half of the participants reported game-induced fear. Sex, sensation-seeking, and empathy all emerged as important individual differences in terms of enjoyment of frightening content, consumption of frightening content, and frequency of fright experience. Interactivity and presentations of realism also predicted fear. This work identifies titles, stimuli, and features that caused fright experience.     

Correlation between serum lipid profile and carotid intima-media thickness in Polycystic Ovarian Syndrome

Abnormal lipid profile is often found in women with Polycystic Ovary Syndrome. To assess the impact of abnormal lipid profile on atherosclerosis in young Polycystic Ovary Syndrome women, carotid intima-media thickness as judged by B-mode ultrasonography were done in 30 young (18–35 yrs) Polycystic Ovary Syndrome women and in similarly age-matched 30 apparently healthy controls. Compared to controls, young Polycystic Ovary Syndrome women had significantly elevated serum total cholesterol, triglyceride and LDL-C levels and carotid intima-media thickness. HDL-C level did not differ significantly between two groups of women. In Polycystic Ovary Syndrome women carotid intima-media thickness was positively correlated with serum total cholesterol, triglyceride and LDL-C and negatively correlated with serum HDL-C. Our study suggests that even young Polycystic Ovary Syndrome women are prone to atherosclerosis from early age.
