Modelos didáticos como uma proposta no ensino de genética na aprendizagem do aluno
Anais do II Seminário Seminário Estadual PIBID do Paraná: tecendo saberes / organizado por Dulcyene Maria Ribeiro e Catarina Costa Fernandes — Foz do Iguaçu: Unioeste; Unila, 2014O presente trabalho teve como principal objetivo apresentar a importância do uso dos
modelos didáticos em sala de aula no ensino de Biologia a fim de sugerir como o educador pode fazer
uso destes recursos para facilitar a compreensão dos alunos em relação aos conteúdos de genética.
Para isso foram construídos três modelos tridimensionais, sendo um da cromatina, um do cromossomo
e um da fita dupla de DNA com material reciclável. Estes recursos são importantes por favorecerem a
visualização destas estruturas, em vez de ocorrer somente a tentativa de abstração do aluno durante a
explicação do professor, resultando, assim, na construção do conhecimento em relação aos conceitos
de genétic
A physical activity intervention for children with type 1 diabetes- steps to active kids with diabetes (STAK-D): a feasibility study
Background
This study describes the development and feasibility evaluation of a physical activity intervention for children with type 1 diabetes called ‘Steps to Active Kids with Diabetes’ (STAK-D). It aims to explore the feasibility and acceptability of the intervention and study design.
Methods
Thirteen children aged 9-11 years and their parents were recruited from one paediatric diabetes clinic. A process evaluation was conducted alongside a two-arm randomised feasibility trial, including assessment of rate of recruitment, adherence, retention, data completion and burden, implementation fidelity and adverse events. Qualitative interviews with children (n=9), parents (n=8), healthcare professionals (n=3) and STAK-D volunteers (n=8) explored intervention acceptability. Interviews were analysed thematically.
Results
Rate of recruitment was 25%, with 77% retention at 3-month follow-up. Study burden was low, data completion was high and the intervention was delivered as per protocol. No serious adverse event was reported. Engagement with intervention materials was generally good, but attendance at group activity sessions was low due to logistical barriers. Interview analysis identified preferred methods of recruitment, motivations for recruitment, barriers and facilitators to adherence, the experience of data collection, experience of the STAK-D programme and its perceived benefits.
Conclusions
STAK-D was feasible and acceptable to children, their parents and healthcare professionals, but group sessions may present logistical issues. Recruitment and retention may be improved with a clinic-wide approach to recruitment.
Trial registration
This trial was registered on ClinicalTrials.gov: NCT02144337 (16/01/2014).

Virtual reality exposure using three-dimensional images for the treatment of social phobia
Virtual Reality and Anxiety Disorders Treatment: Evolution and Future Perspectives
Virtual reality (VR) is a technology that allows the simulation of different real-life situations on a tridimensional computer-generated environment where the user can interact with the environment as if he/she were the real world. VR has potential as an exposure technique for treating anxiety disorders because VR and real objects have similar characteristics, which creates the illusion that the user is immersed and engaged with objects in the real world. Regarding the efficacy of using virtual reality exposure-based therapy (VR-EBT), for more than two decades, there has been sufficient empirical evidence regarding VR-EBT for treating anxiety disorders. Finally, this chapter ends with some directions and perspectives for future VR-EBT developments and treatments protocols
Personalized Exercise for Adolescents With Diabetes or Obesity
Objective: This study examined adherence to a personalized, community-based exercise intervention by sedentary adolescents with type 1 or type 2 diabetes or those with obesity. Research design and Methods: We conducted a pretest–posttest investigation to explore the application of an individualized exercise prescription based upon current fitness level for 39 adolescents (20 with type 1 diabetes, 9 with type 2 diabetes, and 10 obese) over 16 weeks in community settings. Subjects were recruited from a university-based pediatric endocrinology clinic in the southwestern United States. Adherence to the exercise prescription was monitored using accelerometers over the entire intervention period. Results: Moderate-to-vigorous physical activity (MVPA) levels significantly increased over sedentary baseline values ( p < .001), but the average of 42.5 ± 22.1 min/day of MVPA determined at the end of the study was still less than the recommended 60 min/day. Perceptions of health were significantly increased for the total group following the intervention ( p = .008). For those with type 1 diabetes, there was a significant association between MVPA duration and percentage change in HbA1c ( r = −.526, p = .02). Conclusions: Recruitment and retention of adolescent participation in daily exercise is challenging. Personalized approaches that include adolescent choices with family support and ongoing motivation can improve individual exercise adherence and a sense of personal health. </jats:sec
