Core Viewpoint - The increasing popularity of educational trips for students during holidays is noted, but there is a significant lack of ecological understanding and knowledge in the design and practice of these trips, leading to superficial learning experiences [1][2]. Group 1: Current Issues in Educational Trips - Many educational trips are marketed with themes like "natural exploration" and "outdoor practice," yet they often fail to incorporate ecological concepts and knowledge [1]. - Students may learn the names of plants and animals but do not grasp the interdependence within ecosystems or the deeper logic of sustainable development [1]. - The design of these trips often emphasizes "experiential learning" over "immersive thinking," resulting in a lack of systematic explanation of ecological principles [1][3]. Group 2: Importance of Ecological Concepts - Educational trips are described as "walking classrooms," where integrating ecological theories is essential to instill respect for nature and the protection of life in children [2]. - The need for a comprehensive understanding of ecological systems is emphasized, suggesting that ecological principles should be woven into every aspect of the educational experience [2]. Group 3: Recommendations for Improvement - The article suggests four key integrations to embed ecological concepts into educational trips: - Integrate ecological system concepts during natural observations, using visual aids to explain energy flow and interconnections within ecosystems [3]. - Incorporate ecological balance concepts through practical experiences, such as comparing different human interventions on vegetation recovery [3]. - Include sustainable development concepts in scenario analyses, using local examples to illustrate the symbiotic relationship between development and environmental protection [3]. - Promote harmonious coexistence through action-oriented guidance, encouraging children to engage in environmental protection activities [4].
