Mars Explorers: A Science Inquiry-Based Learning Project in Preschool

Inquiry-based science education has become one of the most effective methodologies to learn science; however, proposals in preschool are scarce. Different factors are responsible for this situation, such as the low self-confidence of teachers to teach science and the belief that young children are unable to develop certain reasoning skills. This study reports the implementation of an inquiry-based science project in a preschool setting, in the context of a preservice teacher’s school placement. The project aimed to promote the development of basic and integrated scientific skills, enhance acquisition of conceptual knowledge and make the students enjoy while learning science. The intervention is described thoroughly and illustrated with examples from the real implementation of the theoretical IBSE sequence. At the beginning of the proposal, the students received a hypothetical letter from the astronaut Pedro Duque, in which they were asked for help to plan his trip to living on Mars, a cold planet, with only frozen and saltwater. After some introductory POE (predict, observe, and explain) experiences on the perception of temperature and activities with fresh and saline water, the students performed a piece of research: growing lettuce in four different conditions, combining two variables: temperature and the salinity of water. As the project developed, the students progressively gave better descriptions and justifications, and also showed great interest in performing more “research experiments”. For the preservice teacher, the project provided an excellent opportunity to implement academic knowledge in school practice.

Evaluation of an Early Start Denver Model-based intervention for young children with autism in an inclusive preschool setting.

<p>Autism spectrum disorder (ASD) is a neurodevelopmental disorder defined by difficulties in social communication and the presence of restricted or repetitive behaviours or interests. There is evidence to suggest that early intervention (EI) can lead to improved outcomes for children with ASD. Inclusive preschool-based delivery of EI appears to satisfy current legal and best-practice recommendations around the delivery of EI for young children with ASD. It may also offer several potential benefits including cost-effectiveness, efficiency and opportunities for children with ASD to learn from their peers. The Early Start Denver Model (ESDM) is a promising naturalistic behavioural developmental intervention for young children with ASD aged between 12 and 60 months. The ESDM can be delivered to children in a group-based format and several studies have demonstrated its effectiveness when delivered for 15 to 25 hours per week in designated ESDM preschools with low child–teacher ratios. However, the preschools involved in these studies may not be representative of the typical preschool setting for many communities. Thus, more research is needed to determine the effectiveness of this intervention when delivered under conditions that more closely reflect the typical real-world preschool setting. In the present thesis, two studies with multiple probe across participants designs, each involving three preschool children with ASD, examined the feasibility and effectiveness of the use of the ESDM in an inclusive preschool setting. Specifically, Study 1 evaluated the effectiveness of a modified version of ESDM therapy delivered by a certified therapist and Study 2 evaluated (a) the effectiveness of a brief ESDM coaching programme, and (b) the effectiveness of a modified version of ESDM therapy delivered by preschool teachers. For both studies, the intervention was delivered in regular community preschools and no major changes were made to the typical preschool environments or routines. Effectiveness was assessed by measuring improvements in child active participation, vocal/verbal communication and imitation, and, for Study 2, teachers’ fidelity of implementation of ESDM techniques. Teachers’ perceptions of the acceptability and effectiveness of the intervention were also assessed via a questionnaire and in-depth interviews. In Study 1, an outside certified therapist delivered 3 hours per week of ESDM to three children with ASD over an 8- to 10-week period. Participants showed improvement in active participation, imitation and either intentional vocalisations or spontaneous functional utterances. These results were generally maintained at follow-up. For Study 2, a brief coaching programme was used to train three preschool teachers to use the ESDM with a child with ASD who attended the inclusive preschools where they worked. Teachers improved in their use of the ESDM strategies and children demonstrated improved levels of active participation but results for child imitation and communication were mixed. Teachers also found the intervention to be acceptable and effective. Together, the results from these studies provide preliminary support for the feasibility and effectiveness of the ESDM when delivered in real-world inclusive preschool settings. More research is needed to determine the most effective approach to delivering EI for ASD in an inclusive preschool setting. It may also be valuable to evaluate the extent to which gains made by children and teachers during intervention generalise to other people and/or settings.</p>

Integrating Augmentative and Alternative Communication Into a Stay-Play-Talk Program in Preschool

Stay-Play-Talk (SPT) is a peer-mediated intervention used to increase social interactions between preschoolers with developmental disabilities and typically developing (TD) peers. This intervention has been found to be successful in increasing play and reciprocal conversation amongst children with and without disabilities. The following describes how to implement a Stay-Play-Talk intervention with children who use Augmentative and Alternative Communication (AAC) devices in a preschool setting.

Changing the preschool setting to promote healthy energy balance-related behaviours of preschoolers: a qualitative and quantitative process evaluation of the SuperFIT approach

Background The Early Care and Education (ECE) setting plays an important role in the promotion of a healthy lifestyle in young children. SuperFIT is a comprehensive, integrated intervention approach designed to promote healthy energy balance-related behaviours in preschoolers. Insight in the process of implementation and the context in which SuperFIT was implemented supports the understanding of how the intervention works in practice. This process evaluation examined factors that influenced the implementation and maintenance, as well as the (perceived) changes in the ECE setting. Methods A mixed-methods study was conducted. SuperFIT was implemented at twelve preschools in the south of the Netherlands. The process evaluation was performed among preschool teachers, managers of the preschool organisation, and implementers. Semi-structured in-depth (group) interviews, quantitative process questionnaires, the Child-care Food and Activity Practices Questionnaire (CFAPQ) and the Environmental and Policy Assessment and Observation (EPAO) were used to evaluate the implementation and maintenance of SuperFIT and the changes in the preschool setting. The interviews were analysed using a theoretical framework based on the Implementation Framework of Fleuren and Damschröder’s Consolidated Framework for Implementation Research. Descriptive analyses were performed on the quantitative data. Results Various intervention activities were implemented in the preschool setting. Although the intention to maintain SuperFIT was present, this was hindered by time constraints and lack of financial resources. Important factors that influenced implementation and maintenance were incongruence with current practice, limited perceived capabilities to integrate SuperFIT in daily practice, group composition at the preschools, and the perceived top-down implementation. Organizational vision and societal attention regarding healthy behaviour in general were perceived to be supportive for implementation and maintenance. Predominantly, favourable changes were seen in the nutrition- and physical activity-related practices of preschool teachers and other aspects of the social preschool environment such as the use of play materials. Limited changes were observed in the physical preschool environment. Conclusions Several factors influenced the implementation and maintenance of SuperFIT in the preschool setting. Some factors evolved over time from hindering to facilitating, emphasising the importance of allowing sufficient time for intervention implementation. SuperFIT changed mainly the social preschool environment. Trial registration Clinicaltrials.gov, NCT03021980, date registered: January 16, 2017, prospectively registered

“It’s Everyone’s iPad”: Tablet use in a play-based preschool classroom

Although existing literature has established that technologies are utilized in play and can be supportive of learning, utilization of technologies in play-based classrooms is not commonplace. This study is an holistic examination of a successful 2-year process of integrating an iPad into a play-based preschool setting. Each year the use of the iPad increased, demonstrating its applicability in a play-based environment. This study adds to the existing research base by examining the confluence of actors in a play-based setting. As the iPad became a part of the classroom, new practices began to emerge as the children, teachers, and families began using it for their own purposes.

Exploring the Impact of a TPSR Program on Transference of Responsibility Goals within a Preschool Setting: An Action Research Study

The teaching personal and social responsibility (TPSR) model has been extensively used in a vast array of settings. However, few TPSR studies have focused on preschool settings. The purpose of this action research study was to analyze the experiences of a program leader, her preschool children, and their parents throughout a TPSR program focused on transference of responsibility model goals. The participants were 25 preschool children, six parents, and a program leader involved in a preschool setting located in the north of Portugal. Data were collected through reflexive journaling, participant observations, semi-structured interviews, and focus group interviews. Findings suggest the TPSR model could be a useful instructional model for preschool teachers focused on providing social and emotional learning opportunities to their students. In order to foster transference, parents played a pivotal role in this process and were included in the intervention, which appeared to enhance life skill transfer.
