Optimal Scaffolding Methods for Students with Emotional and Behavioural Disorders

Optimal assistance of an adult, adapted to the current level of understanding of the student (scaffolding), can help students with emotional and behavioural problems (EBD) to demonstrate a similar level of understanding on scientific tasks, compared to students from regular education (Van Der Steen, Steenbeek, Wielinski & Van Geert, 2012). In the present study the optimal scaffolding techniques for EBD students were investigated, as well as how these differ from scaffolding techniques used for regular students. A researcher visited five EBD students and five regular students (aged three to six years old) three times in a 1,5 years period. Student and researcher worked together on scientific tasks about gravity and air pressure, while the researcher asked questions. An adaptive protocol was used, so that all children were asked the same basic questions about the mechanisms of the task. Beside this, the researcher was also allowed to ask follow-up questions and use scaffolding methods when these seemed necessary. We found a bigger amount of scaffolding in the group of EBD students compared to the regular students. The scaffolding techniques that were used also differed between the two groups. For EBD students, we saw more scaffolding strategies focused on keeping the student committed to the task, and less strategies aimed at the relationship between the child and the researcher. Furthermore, in the group of regular students we saw a decreasing trend in the amount of scaffolding over the course of three visits. This trend was not visible for the EBD students. These results highlight the importance for using different scaffolding strategies when working with EBD students compared to regular students. Future research can give a clearer image of the differences in scaffolding needs between these two groups.

Applied behavior analysis: What do teachers of students with autism spectrum disorder know?

With rising numbers of school-aged children with autism educated in mainstream classroomsand applied behavior analysis (ABA) considered the basis of best practice, teachers’ knowledgein this field has become a key concern for inclusion. Self-reported knowledge of ABA of specialneeds teachers (n=165) was measured and compared to their actual knowledge of ABAdemonstrated in accurate responses to a multiple-choice test. Findings reported here show thatteachers’ self-perceived knowledge exceeded actual knowledge and that actual knowledge ofABA was not

A Simultaneous Equation Approach to Estimating HIV Prevalence with Non-Ignorable Missing Responses

Estimates of HIV prevalence are important for policy in order to establish the health status of a country's population and to evaluate the effectiveness of population-based interventions and campaigns. However, participation rates in testing for surveillance conducted as part of household surveys, on which many of these estimates are based, can be low. HIV positive individuals may be less likely to participate because they fear disclosure, in which case estimates obtained using conventional approaches to deal with missing data, such as imputation-based methods, will be biased. We develop a Heckman-type simultaneous equation approach which accounts for non-ignorable selection, but unlike previous implementations, allows for spatial dependence and does not impose a homogeneous selection process on all respondents. In addition, our framework addresses the issue of separation, where for instance some factors are severely unbalanced and highly predictive of the response, which would ordinarily prevent model convergence. Estimation is carried out within a penalized likelihood framework where smoothing is achieved using a parametrization of the smoothing criterion which makes estimation more stable and efficient. We provide the software for straightforward implementation of the proposed approach, and apply our methodology to estimating national and sub-national HIV prevalence in Swaziland, Zimbabwe and Zambia.

Efeito de exercícios de pilates clínico no controlo postural de jovens adultos com dor lombar não específica

Introdução: Os efeitos a longo prazo de exercícios de Pilates têm sido bem documentados, não entanto os seus efeitos imediatos no controlo postural estático e dinâmico de jovens adultos com dor lombar não específica permanecem por desvendar. Objetivo: Avaliar os efeitos imediatos de uma sessão composta por 4 exercícios de Pilates Clínico no controlo postural estático e dinâmico de jovens adultos com dor lombar não específica. Métodos: 46 estudantes universitários com dor lombar não específica participaram no estudo randomizado e controlado. Os participantes foram randomizados para um grupo de Pilates (n = 23, 10 do sexo masculino, idade: 21,8 ± 3,2 anos; peso: 64,5 ± 11,5 kg; altura: 1,70 ± 0,1 m) e um grupo controlo (n = 23, 9 do sexo masculino; idade: 22,8 ± 3,6 anos; peso: 62,5 ± 9,9 kg; altura: 1,68 ± 0,1 m). O controlo postural estático foi avaliado com uma plataforma de forças e o controlo postural dinâmico com o Star Excursion Balance Test, antes e depois da intervenção ou período de repouso. Para avaliar o controlo postural estático, os participantes estavam em posição ortostática, o mais quietos possível durante 90s, com os olhos fechados em superfície instável. A intervenção durou 20 minutos e consistiu em 4 exercícios de Pilates Clínico: single leg stretch (nível 1), pelvic press (nível 1), swimming (nível 1) e kneeling opposite arm and leg reach. Resultados: No momento de avaliação inicial, não foram encontradas diferenças estatisticamente significativas entre os grupos em nenhuma das variáveis. Após a intervenção, o grupo Pilates melhorou em todos as variáveis do controlo postural estático (COPx: 5,7 ± 1,0 para 5,1 ± 0,7 cm, p = 0,005; COPy: 4,4 ± 1,0 para 3,8 ± 0,7 cm, p < 0,001; comprimento total: 255,2 ± 55,9 para 210,5 ± 42,7 cm, p < 0,001 ; área: 11,5 ± 3,4 para 9,7 ± 2,7 cm2, p = 0,002 e velocidade : 2,8 ± 0,6 para 2,3 ± 0,5 cm/s, p < 0,001) e no Star Excursion Balance Test (anterior: 65,3 ± 8,3 para 68,6 ± 6,4%, p = 0,001; póstero-medial: 82,6 ± 11,7 para 89,5 ± 9,7%, p < 0,001; póstero-lateral: 83,9 ± 11,0 para 87,6 ± 10,2%, p < 0,001 e composite: 86,2 ± 12,4 para 91,1 ± 11,0%, p < 0,001). O grupo de controlo só melhorou na velocidade (2,8 ± 0,5 para 2,6 ± 0,5 cm/s, p = 0,009) e comprimento total (248,5 ± 45,3 para 237,3 ± 47,2 cm, p = 0,009) no controlo postural estático. No entanto, as melhorias no grupo Pilates foram significativamente maiores do que as do grupo de controlo. Conclusão: Os exercícios de Pilates Clínico melhoraram, no imediato, o controlo postural estático e dinâmico em jovens adultos com dor lombar não específica.

Exercise Prescription for Patients with Non-specific Chronic Low Back Pain: a Qualitative Study of Patients' Experiences in Decision Making

Background The culture of current clinical practice calls for collaboration between therapists and patients, sharing power and responsibility. This paper reports on the findings of a qualitative study of exercise prescription for patients with NSCLBP, taking into account issues such as decision making and how this accords with patient preferences and experiences. Objective To understand the treatment decision making experiences, information and decision support needs of patients with NSCLBP who have been offered exercise as part of their management plan. Design A qualitative study using a philosophical hermeneutic approach. Methods Semi-structured interviews with eight patients (including use of brief patient vignettes) was undertaken to explore their personal experiences of receiving exercise as part of the management of their NSCLBP, and their involvement in decisions regarding their care. Findings The findings provide a detailed insight into patients’ perceptions and experiences of receiving exercise-based management strategies. Four themes were formed from the texts: (1) patients’ expectations and patients’ needs are not synonymous, (2) information is necessary but often not sufficient, (3) not all decisions need to be shared, and (4) wanting to be treated as an individual. Conclusions Shared decision making did not appear to happen in physiotherapy clinical practice, but equally may not be what every patient wants. The overall feeling of the patients was that the therapist was dominant in structuring the interactions, leaving the patients feeling disempowered to question and contribute to the decision making.

We report a case of parotid gland oncocytoma in a patient with chronic infection from hepatitis C virus (HCV) and associated non-Hodgkin's lymphoma and xerophthalmia. Our case confirms the triple tropism of the HCV: hepatotropism, lymphotropism and sialotropism.

Handgrip dynamometry and patient-generated subjective global in patients with non-resectable lung cancer

Rationale: Undernutrition is frequently associated with advanced lung cancer. Accurate nutritional assessment tools are important to provide the proper nutritional therapy. Hand grip strength (HGS) has already been used in these patients and the findings suggest it is a good indicator of nutritional status. The aim of this study was to evaluate the association between nutritional status and hand grip strength in patients with nonresectable lung cancer.

Brief report: preliminary proposal of a conceptual model of a digital environment for developing mathematical reasoning in students with Autism Spectrum Disorders

There is clear evidence that in typically developing children reasoning and sense-making are essential in all mathematical learning and understanding processes. In children with autism spectrum disorders (ASD), however, these become much more significant, considering their importance to successful independent living. This paper presents a preliminary proposal of a digital environment, specifically targeted to promote the development of mathematical reasoning in students with ASD. Given the diversity of ASD, the prototyping of this environment requires the study of dynamic adaptation processes and the development of activities adjusted to each user’s profile. We present the results obtained during the first phase of this ongoing research, describing a conceptual model of the proposed digital environment. Guidelines for future research are also discussed.

School participation of students with autism spectrum disorders

This paper addresses the participation of students with autism spectrum disorders (ASD) in main- stream schools. There are different benefits for ASD students to be educated in an inclusive environment (Gena, 2006; Whitaker, 2004). They challenge the school community by presenting difficulties in essential domains for school activi- ties (Chamberlain, Kasari and Rotheram-Fuller, 2006; Eman and Farrell, 2009; Humphrey and Symes, 2010). Thus, these are students with increased difficulties participating in inclusive environments, reinforcing the need of an ade- quate inclusion process (Gena, 2006; Hall and McGregor, 2000; Hestenes and Carroll, 2000). We characterised this students ’ participation with a questionnaire to the students from mainstream classes in which ASD students were included, a questionnaire applied to each class teacher/head teacher and an interview to four of the school educational assistants. The location of the ASD student in mainstream classroom was also ana- lysed, trying to understand if it influences the quality of ASD students ’ participation, hypothesis- ing that there is an influence. Results showed a good perception of the students with ASD and their behaviour, low frequency of behaviours involving interaction with these students, good feelings about their presence at the school/class and an overall acceptance of them in the peer groups of typical development students. Results are mostly consistent across the different infor- mation sources. We found a significant effect of the location on the quality of participation. Results are mainly consistent with the literature reviewed and enlighten the need to keep making progress on inclusion practices related to ASD students in mainstream schools.

The effect of mobile technology as an active student response system on the acquisition of U.S. history content of secondary students with specific learning disabilities

Students with specific learning disabilities (SLD) typically learn less history content than their peers without disabilities and show fewer learning gains. Even when they are provided with the same instructional strategies, many students with SLD struggle to grasp complex historical concepts and content area vocabulary. Many strategies involving technology have been used in the past to enhance learning for students with SLD in history classrooms. However, very few studies have explored the effectiveness of emerging mobile technology in K-12 history classrooms. ^ This study investigated the effects of mobile devices (iPads) as an active student response (ASR) system on the acquisition of U.S. history content of middle school students with SLD. An alternating treatments single subject design was used to compare the effects of two interventions. There were two conditions and a series of pretest probesin this study. The conditions were: (a) direct instruction and studying from handwritten notes using the interactive notebook strategy and (b) direct instruction and studying using the Quizlet App on the iPad. There were three dependent variables in this study: (a) percent correct on tests, (b) rate of correct responses per minute, and (c) rate of errors per minute. ^ A comparative analysis suggested that both interventions (studying from interactive notes and studying using Quizlet on the iPad) had varying degrees of effectiveness in increasing the learning gains of students with SLD. In most cases, both interventions were equally effective. During both interventions, all of the participants increased their percentage correct and increased their rate of correct responses. Most of the participants decreased their rate of errors. ^ The results of this study suggest that teachers of students with SLD should consider a post lesson review in the form of mobile devices as an ASR system or studying from handwritten notes paired with existing evidence-based practices to facilitate students’ knowledge in U.S. history. Future research should focus on the use of other interactive applications on various mobile operating platforms, on other social studies subjects, and should explore various testing formats such as oral question-answer and multiple choice. ^
