Abstract
Early childhood educators (ECEs) are ideally positioned to support the development of children's fundamental movement skills (FMS). However, ECEs have little specialised training to support the development of FMS in young children. This study aimed to assess the impact of an e-Learning course on the FMS of preschool-aged children. 145 Preschool-aged children and 42 ECEs from 12 childcare centres participated in the study. ECEs in the experimental group were asked to complete the e-Learning course. A subsample of children (n = 48) was objectively assessed using the Test of Gross Motor Development 3rd Edition (TGMD-3). Additionally, parents of all participating children reported perceptions of their child's FMS to understand if they knew how well their child was progressing. Findings showed a significant increase in TGMD-3 assessed locomotor skills from baseline to follow-up in the intervention group compared to the control group and total FMS but not objective control skills. Parent-reported FMS increased in the intervention group for all locomotor, object control skills, and total FMS. However, the intervention effect for all three measurements was not significant. The results from this study highlight the potential utility of online professional development for ECEs as an approach to improving young children's FMS.

Efficacy of a Physical Activity e-Learning Course Delivered to Early Childhood Educators on Preschoolers' Physical Activity and Sedentary Behaviors: A Cluster Randomized Controlled Trial. Pediatr Exerc Sci 2024:1-9. [PMID: 39117308 DOI: 10.1123/pes.2023-0180] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/20/2023] [Revised: 05/06/2024] [Accepted: 05/14/2024] [Indexed: 08/10/2024]
Abstract
PURPOSE This study examined the effectiveness of an early childhood educator (ECE)-focused physical activity e-Learning course on children's physical activity and sedentary time in childcare. METHODS A cluster randomized controlled trial was conducted in 12 childcare centers in London, Ontario, Canada. A total of 145 preschoolers and 42 ECEs participated in this study. ECEs in the intervention condition completed a 5-hour e-Learning course related to physical activity. Outcomes were preschoolers' minutes of moderate- to vigorous-intensity physical activity, light-intensity physical activity, and sedentary time assessed using accelerometers. RESULTS The intervention did not have a significant effect on moderate- to vigorous-intensity physical activity (d < 0.01, P = .984), light-intensity physical activity (d = -0.17, P = .386), or sedentary time (d = 0.07, P = .717) from baseline to postintervention. There was also no significant intervention effect on moderate- to vigorous-intensity physical activity (d = 0.27, P = .260), light-intensity physical activity (d = -0.08, P = .740), or sedentary time (d = -0.15, P = .520) from baseline to follow-up. CONCLUSIONS Providing ECEs with online training in physical activity through an e-Learning course may not be sufficient to increase physical activity levels among young children in their care. It may be essential to deliver multicomponent interventions to increase preschoolers' engagement in physical activity in childcare.

The efficacy of the TEACH e-Learning course at improving early childhood educators' physical activity and sedentary behaviour self-efficacy, knowledge, intentions, and perceived behavioural control: a randomized controlled trial. Int J Behav Nutr Phys Act 2024; 21:79. [PMID: 39039543 PMCID: PMC11265122 DOI: 10.1186/s12966-024-01628-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2023] [Accepted: 07/12/2024] [Indexed: 07/24/2024] Open
Abstract
BACKGROUND Early childhood educators play a critical role in promoting physical activity and reducing sedentary time in childcare centres. However, early childhood educators receive limited specialised pre- and in-service learning opportunities relating to these behaviours and may lack the capacity to effectively engage children in healthy movement behaviours. This study aimed to examine the efficacy of an e-Learning course on increasing early childhood educators' physical activity and sedentary behaviour-related capacities. METHODS A two-group parallel randomized controlled trial was conducted with early childhood educators in Canada (Mage = 41.78, 97% female). Participants randomized to the intervention group were asked to complete a physical activity and sedentary behaviour e-Learning course within a 4-week period. Participants randomized to the waitlist control condition were assigned to a waitlist to receive the intervention after the testing period. Participants reported on their self-efficacy, knowledge, intentions, and perceived behavioural control relating to physical activity and sedentary behaviours at baseline, post-intervention, and 3 months follow-up. Linear mixed effects models were estimated to determine difference in changes in outcomes from baseline to post-intervention, and follow-up. RESULTS A total of 209 early childhood educators participated in the study (intervention n = 98; control n = 111). The TEACH e-Learning course was found to be efficacious at improving all of the examined outcomes, with standardized effect sizes ranging from d = 0.58 to d = 0.65 for self-efficacy outcomes, d = 0.66 to d = 1.20 for knowledge outcomes, d = 0.50 to d = 0.65 for intention outcomes, and d = 0.33 to d = 0.69 for perceived behavioural control outcomes post-intervention. The intervention effects were sustained at follow-up for all outcomes apart from perceived behavioural control to limit screen time. Additionally, the magnitude of the effect for knowledge outcomes decreased at follow-up, with standardized effect sizes ranging from d = 0.49 to d = 0.67. CONCLUSIONS The e-Learning course was highly successful at improving early childhood educators' capacity pertaining to physical activity and sedentary behaviours. Providing training content through e-Learning may be an efficacious approach to providing continual professional learning opportunities relating to physical activity and sedentary time to early childhood educators on a large scale.

Effect of capacity building interventions on classroom teacher and early childhood educator perceived capabilities, knowledge, and attitudes relating to physical activity and fundamental movement skills: a systematic review and meta-analysis. BMC Public Health 2024; 24:1409. [PMID: 38802762 PMCID: PMC11129429 DOI: 10.1186/s12889-024-18907-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2023] [Accepted: 05/21/2024] [Indexed: 05/29/2024] Open
Abstract
BACKGROUND Capacity building may play an important role in improving classroom teachers' and early childhood educators' (ECE) capacity to implement physical activity and FMS interventions. Capacity building is the development of knowledge, skills, and structures to improve the capability of individuals and organisations to achieve effective health promotion. This review aimed to determine the efficacy of capacity building interventions on teachers' and ECEs' perceived capabilities, knowledge, and attitudes relating to physical activity and fundamental movement skills. METHODS An exhaustive literature search of six electronic databases was conducted. Controlled, single-group pre-post studies were included if they measured the effect of a capacity building intervention on in-service or pre-service classroom teachers' (primary or secondary) or ECEs' physical activity or fundamental skills related perceived capabilities, knowledge, or attitudes. The effects of interventions were synthesised using random effects meta-analysis. Subgroup analysis and meta-regression was conducted to determine if the effects differed based on study design, type of teacher (ECE vs. primary school), or teacher level (pre-service vs. in-service). RESULTS A total of 22 studies reporting on 25 unique samples were included in the meta-analyses. Only studies reporting on ECEs and primary school teachers were identified. Interventions most commonly included training/professional development, resources and toolkits, communities of practice, mentorships, and ongoing support. Results showed that capacity building interventions significantly improved teachers' and ECEs' perceived capabilities (g = 0.614, 95% CI = 0.442, 0.786), knowledge (g = 0.792 95% CI = 0.459, 1.125), and attitudes (g = 0.376 95% CI = 0.181, 0.571). The effects did not differ significantly as a function of any of the moderators examined. CONCLUSION Findings from this review provide strong support that capacity building interventions are efficacious at improving teachers' and ECEs' perceived capabilities, knowledge, and attitudes related to promoting physical activity and teaching fundamental movement skills. Pre-service teachers and ECEs should be provided training in physical activity and fundamental movement skills as part of their degrees, and continual professional development and capacity building should be offered to in-service teachers and ECEs to promote physical activity and fundamental movement skills in children.

Abstract
Limited research investigates early childhood education and care (ECEC) educators' involvement in promoting physical activity. The aim was to identify distinct profiles based on physical activity-related practices and psychosocial factors in ECEC educators and examine how they relate to the amount of time allocated to children's physical activity. A secondary analysis of educator-reported survey data from the Play Active study was undertaken. Educators (n = 532) reported on four practices and four psychosocial subscales adapted from the Environment and Policy Evaluation and Observation relating to the provision of physical activity in childcare. Latent profile analysis was used to identify distinct groups of educators based on their practices and psychosocial factors. Logistic regression analysed associations between latent profiles and educator-reported time provided for children's physical activity. Five profiles of educators' physical activity-related practices and psychosocial factors were identified. Profiles with higher practice scores also had higher psychosocial scores. Educators in profiles characterised by higher scores had greater odds of meeting the best practice guidelines for daily time allocated to children for total physical activity and energetic play. This study highlights interventions which address multiple educator behaviour change determinants to improve children's physical activity in childcare.

CHILDREN (BASEL, SWITZERLAND) 2023; 10:1346. [PMID: 37628345 PMCID: PMC10453272 DOI: 10.3390/children10081346] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/18/2023] [Revised: 08/01/2023] [Accepted: 08/01/2023] [Indexed: 08/27/2023]
Abstract
Children's outdoor risky play is important for healthy development. However, Early Childhood Educators (ECEs) concern for child safety often restricts risky play affordances during childcare. To reduce this trend, an Outdoor Play Risk Re-Framing workshop was delivered to ECEs in London, Ontario, and the immediate/short-term impact of the workshop on ECEs' knowledge, self-efficacy, and risk tolerance for engaging children in outdoor risky play was examined. Via a natural experiment, using a quasi-experimental design, ECEs in the experimental group (n = 119) completed an Outdoor Play Risk Re-Framing workshop, while ECEs in the comparison group (n = 51) continued their typical curriculum. All ECEs completed the same survey assessing their knowledge (n = 11 items), self-efficacy (n = 15 items), and risk tolerance (n = 27 items) at baseline and 1-week post-intervention. A maximum likelihood linear mixed effects model was conducted, while deductive content analysis was used for open-ended items. The workshop intervention resulted in significant improvements in ECEs' self-efficacy (p = 0.001); however, no significant changes were observed for knowledge (i.e., awareness and practices; p = 0.01 and p = 0.49, respectively) or risk tolerance (p = 0.20). Qualitative data revealed similar findings across both groups, highlighting physical development as a benefit to outdoor risky play and fear of liability as a barrier. In conclusion, providing ECEs with an Outdoor Play Risk Re-Framing workshop shows promise for supporting their self-efficacy to promote this behavior but does not impact ECEs' knowledge or risk tolerance to lead outdoor risky play.

Abstract
E-learning is an innovative strategy for enhancing teaching and learning in digital environments with the goal of enhancing education. In the same context, recommendation models have been developed for predicting the user’s learning preferences. A task that has become urgently necessary is enhancing the learning process by designing recommendation models for e-learning software that then helps users choose the most pertinent learning materials (contents) from a wide number of sources. The general consensus is that designing a recommendation model for e-learning is influenced by parameters that are related to e-learning, and much effort has been exerted to determine those parameters. However, no agreement has been reached as to what constitutes such parameters. Keeping this issue in mind, this study aims to identify the parameters that should be considered when generating e-learning recommendations in developing countries. On the basis of the relevant literature, with the use of the Delphi method and with aid from e-learning experts, this paper identifies ten critical parameters related to e-learning. The results show that perceived ease of use is the most critical parameter out of the ten e-learning-related parameters, while user preference is the parameter that contributes least to e-learning.

Implementation of an e-Learning course in physical activity and sedentary behavior for pre- and in-service early childhood educators: Evaluation of the TEACH pilot study. Pilot Feasibility Stud 2022; 8:64. [PMID: 35300723 PMCID: PMC8927755 DOI: 10.1186/s40814-022-01015-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/16/2021] [Accepted: 02/25/2022] [Indexed: 11/10/2022] Open
Abstract
Background Childcare-based physical activity (PA) and sedentary behavior (SB) interventions have traditionally used in-person training to supplement early childhood educators’ (ECEs) knowledge and confidence to facilitate physically active programming for the children in their care. However, this method of delivery is resource-intensive and unable to reach a high number of ECEs. The purpose of the Training pre-service EArly CHildhood educators in PA (TEACH) pilot study was to test the implementation (e.g., fidelity, feasibility, acceptability) of an e-Learning course targeting PA and SB among a sample of pre-service (i.e., post-secondary students) and in-service (i.e., practicing) ECEs in Canada. Methods A pre-/post-study design was adopted for this pilot study, and implementation outcomes were assessed cross-sectionally at post-intervention. Pre-service ECEs were purposefully recruited from three Canadian colleges and in-service ECEs were recruited via social media. Upon completing the e-Learning course, process evaluation surveys (n = 32 pre-service and 121 in-service ECEs) and interviews (n = 3 pre-service and 8 in-service ECEs) were completed to gather ECEs’ perspectives on the e-Learning course. Fidelity was measured via e-Learning course metrics retrieved from the web platform. Descriptive statistics were calculated for quantitative data, and thematic analysis was conducted to analyze qualitative data. Results Moderate-to-high fidelity to the TEACH study e-Learning course was exhibited by pre-service (68%) and in-service (63%) ECEs. Participants reported that the course was highly acceptable, compatible, effective, feasible, and appropriate in complexity; however, some ECEs experienced technical difficulties with the e-Learning platform and noted a longer than anticipated course duration. The most enjoyed content for pre- and in-service ECEs focused on outdoor play (87.5% and 91.7%, respectively) and risky play (84.4% and 88.4%, respectively). Conclusions These findings demonstrate the value of e-Learning for professional development interventions for ECEs. Participant feedback will be used to make improvements to the TEACH e-Learning course to improve scalability of this training.
