Effect of phonological training on reading and writing acquisition

The aim of our study was to determine the effect of training of phonological abilities upon the acquisition of reading and writing during the first year of primary school. An experimental design, with five groups of subjects matched by age, sex, IQ, phonological abilities and reading and writing level was used. Every group received twenty training sessions, over a period of six months. Four groups had different training procedures depending upon the type of task used (phoneme versus concept discrimination) and the way that the task was carried out (using or not using manipulative materials). The fifth group served as control. Post training measures were taken in reading, writing, and mathematics, besides the teacher's estimated scores, twice: immediately after the end of training sessions and two months later. Significant effects on both reading and writing measures were obtained for the groups trained on phonological activities using manipulative materials. The effects were reliable for the two tests. The theoretical implications of the results are discussed and their implications for educational practice are indicated.     

Supporting Student Teachers' Professional Learning with Standards‐Referenced Assessment

Professional standards in teaching are developed in many education systems, with professional learning and quality assurance being the central purposes of these standards. This paper presents an initiative in developing a professional development progress map (hereafter, progress map) within a learning‐oriented field experience assessment (LOFEA) framework. The article examines the use of a progress map to support professional learning in teaching supervision in the field experience of a teacher education programme. Views of users, including 16 tertiary supervisors and 21 teacher participants of the in‐service programmes, were collected. Issues relating to supporting student teachers' professional learning with standards‐referenced assessment, are discussed around four themes, namely intention, instrumentation, interpretation and implementation.     

Defining content for field-based coursework: Contrasting the perspectives of secondary preservice teachers and their teacher preparation curricula

The current study examined changes and continuities in how 11 secondary teacher preparation programs and 743 preservice teachers conceptualized the content and sequence of field-based teacher preparation. Although curricula and candidates differed regarding the knowledge each deemed as most relevant for field-based preparation, they largely agreed on the types of learning activities considered as most meaningful for the acquisition of that knowledge base. Possible explanations for these discrepancies and continuities are discussed.     

A cross‐sectional study of fluency and reading comprehension in Spanish primary school children

The importance of prosodic elements is recognised in most definitions of fluency. Although speed and accuracy have been typically considered the constituents of reading fluency, prosody is emerging as an additional component. The relevance of prosody in comprehension is increasingly recognised in the latest studies. The purpose of this research is to examine the contribution of prosodic reading to comprehension beyond automaticity in word reading, taking into account children's grade level. One hundred and twenty‐two Spanish children (74 second and 48 fourth graders) were tested in prosodic reading, automaticity in word reading (nonword reading and reading rate) and comprehension abilities. Results show that the contribution of automaticity in word reading is relevant in both grades; however, it is more significant in Grade 2. The prosodic components of reading seem to be related differently to comprehension across grades, intonation being the highest predictor of comprehension in Grade 4. Implications for educational practice are discussed.     

Aerobic exercise did not have compensatory effects on physical activity levels in type 2 diabetes patients

Although exercise promotes beneficial effects in diabetic patients, some studies have questioned the degree of their importance in terms of the increase in total energy expenditure. In these studies, the decrease of physical activity levels (PAL) was referred as “compensatory effect of exercise”. However, our aim was to investigate whether aerobic exercise has compensatory effects on PAL in type 2 diabetes patients. Eight volunteers (51.1 ± 8.2 years) were enrolled in a supervised exercise programme for 8 weeks (3 d · wk^?1, 50–60% of VO₂ peak for 30–60 min). PAL was measured using tri-axial accelerometers in the 1st, 8th and 12th weeks. Biochemical tests, cardiorespiratory fitness, anthropometric assessment and body composition were measured in the 2nd and 11th weeks. Statistical analysis was performed using non-parametric tests (Friedman and Wilcoxon, P < 0.05). We found no significant differences in PAL between intervention periods, and participants spent the majority of their awake time in sedentary activities. However, the exercise programme generated a significant 14.8% increase in VO₂ peak and a 15% reduction in fructosamine. The exercise programme had no compensatory effects on PAL in type 2 diabetes patients, but improved their cardiorespiratory fitness and glycaemic control.     

Quality input and sustainability in early immersion classrooms: A case study of an experimental school in Macao

This paper looks into the case of a school in Macao nominated as the first (and so far the only) China-Canada-United States English Immersion (CCUEI) centre in the Macao Special Administrative Region (Macao SAR) China for the experimentation and application of English immersion instruction (EI) in the K1-3 and Primary 1–2 classes. Drawing on Krashen’s Input Hypothesis (1982) and Cummins’ (2000) framework of instruction for language learning and academic achievement in the formal school context, the authors report their observations by analyzing the data collected from school teachers and participation in classes and by reflecting on their experiences, and suggest improvement that can be made to teachers’ linguistic and communicative competence, in terms of quantity and quality of comprehensible input and expected output, and thus the sustainability of English immersion classrooms in a Chinese context.     

Mass deacidification of papers and books: V. Fungistatic properties of papers treated with aminoalkylalkoxysilanes

A new process using aminoalkylalkoxysilanes (AAAS) was developed recently for paper and book mass deacidification. This process is entirely novel in that, besides deacidifying, it also improves the mechanical properties of paper. In the present article, the properties of inhibition of fungal growth of the treated papers are investigated. It was found that the AAAS tested acted as surface-active antifungal agents when introduced in the paper, significantly reducing the growth of Aspergillus niger and Paecilomyces variotii, two fungal species commonly found in storage areas of libraries and archives. The AAAS which seemed the most efficient in preventing the fungal development was 3-aminopropylmethyldimethoxysilane (AMDES), functionalised with a primary amine. The effect was significant in the different papers tested which demonstrated the protection against the proliferation of filamentous fungi in vitro for papers treated with AMDES. The higher concentration of AMDES inside the paper proved to be the most effective. The highest efficiency was reached for AAAS uptakes around 6%. At this concentration the sporulation of the two strains was inhibited and the development of A. niger mycelia was highly reduced.     

The Critical Role of Stereopsis in Virtual and Mixed Reality Learning Environments

Anatomy education has been revolutionized through digital media, resulting in major advances in realism, portability, scalability, and user satisfaction. However, while such approaches may well be more portable, realistic, or satisfying than traditional photographic presentations, it is less clear that they have any superiority in terms of student learning. In this study, it was hypothesized that virtual and mixed reality presentations of pelvic anatomy will have an advantage over two-dimensional (2D) presentations and perform approximately equal to physical models and that this advantage over 2D presentations will be reduced when stereopsis is decreased by covering the non-dominant eye. Groups of 20 undergraduate students learned pelvic anatomy under seven conditions: physical model with and without stereo vision, mixed reality with and without stereo vision, virtual reality with and without stereo vision, and key views on a computer monitor. All were tested with a cadaveric pelvis and a 15-item, short-answer recognition test. Compared to the key views, the physical model had a 70% increase in accuracy in structure identification; the virtual reality a 25% increase, and the mixed reality a non-significant 2.5% change. Blocking stereopsis reduced performance on the physical model by 15%, on virtual reality by 60%, but by only 2.5% on the mixed reality technology. The data show that virtual and mixed reality technologies tested are inferior to physical models and that true stereopsis is critical in learning anatomy.
