{"abstract":"This phenomenological qualitative research described the challenges, opportunities, innovations, and best practices of pupils, parents, and teachers in establishing learning spaces at home. The study involved seven pupils, seven parents, and seven teachers from the District of Cuartero, Schools Division of Capiz. Data were gathered through face-to-face interviews using validated interview guide questions and a checklist, then transcribed, coded, analyzed, and thematized. Challenges included lack of time, budget, knowledge about home learning spaces, and materials, which were overcome by seeking advice, using available materials, and purchasing necessities. Opportunities identified were that learning spaces motivate learners, regulate study habits, offer comfort, are conducive to learning, foster creativity, utilize recycled materials, and facilitate family bonding. Innovations included using local/indigenous materials, recycling, and integrating educational technologies for comfort and study. Best practices involved maximizing existing space, family collaboration, ensuring coziness and safety, and making the most of available resources.","abstract_source":"gemini_shortened","authors":["Stewart Arroyo"],"date":"2023-07-04","doi":"10.5281/zenodo.8111594","id":1574,"issue":3,"journal":{"issn":"2822-4353","name":"Psychology and Education: A Multidisciplinary Journal"},"pdf_sha256":"f12081d1e648d6b4829aafa0bc7b5a49e99699434c91ef33e7937ba5eefeb5da","schema":"scimatic-article/1","title":"Learning Space at Home: Challenges, Opportunities, Innovations, and Best Practices","volume":10}
