Objective: The purpose of this literature review is to examine the most psychometrically sound (e.g., valid and reliable) instruments measuring physical activity (PA) so that reflection of preschool children’s activity and documentation of intervention effects on preschool child PA is accurate.
Methods: Rigorous validation and calibration studies and those studies designed to test the psychometric properties of PA measurement instruments were specifically sought out to include in this review. Articles were excluded if they did not include specific information about the validity and reliability of the PA measures used with preschool children.
Discussion: Of the six articles reviewed, the systematic review used the most rigorous protocols to conduct its review, yielding the highest level of evidence appraising several validation studies. Because Pfeiffer et al. (2006) utilized the most valid and reliable criterion measure (Cosmed® portable metabolic system), the validation study this research team conducted is deemed to have identified the most valid and reliable cut points to utilize when reducing accelerometry data.
Conclusion: Current cut-points vary widely and greatly affect the reported results of a study. Therefore, it is critical that authors reference validation studies used to support the cut-points that were employed in the data-reduction phase. Currently, validation methods have been identified using high quality criterion measures in rigorous validation studies and thus it is strongly recommended that those cut points be used in data reduction processes.
etworking and a tool for stress coping methods.
With this blog, it is my objective to aid my peers who might need help recognizing and coping with stress by the following methods:
a) Actualize the burden of Stress—Chronic stress is a burden and can be overwhelming if not managed. By disclosing my own stressors, it is my hope that peers will identify with me, so that I can then change the way they view and handle the stress.
b) Discuss the psychological and physical effects of stress on the body—It is my intent to clarify how unmanaged chronic stress can affect the physical and mental health and how acute stress is normal and healthy.
c) Share my coping methods that I have found effective in five minute or less videos with blurbs about how and why they are effective. I believe showing them to you in these mostly raw and unedited videos help maintain the current theme I am going for—keep things as real and raw as possible. Hopefully, these raw videos will help peers visualize working coping methods!
This research paper assesses the effectiveness of a remote garden-based learning curriculum in teaching elementary students’ basic systems thinking concepts. Five remote lessons were designed, covering different garden topics, and in order to integrate systems thinking concepts, the Systems Thinking Hierarchical Model was used. This model includes eight emergent characteristics of systems thinking necessary for developing systems thinking competency. Five students were given the remote garden-based learning lessons. Student work was evaluated for systems thinking understanding and student outcomes were compared to anticipated learning outcomes. Results suggest that elementary students are able to understand basic systems thinking concepts because student work met anticipated outcomes for four systems thinking characteristics and exceeded anticipated outcomes for one characteristic. These results are significant because they further confirm that elementary-aged students do have the ability to understand systems thinking and they contribute to a growing movement to integrate sustainability education into elementary curriculum.
