結合立體結構互動教具實驗提升學童之海洋保育研究

Enhancing Marine Conservation Education for Elementary School Students through Interactive 3D Teaching Aids - A Case Study on the Echolocation System of Cetaceans and Environmental Simulation Box

本研究的重點是鯨豚回聲定位系統的重要性及其在海洋環境中的關鍵作用，並將其製作成教具，應用於海洋保育課程中，以提升學生對海洋生物的認識、培養科學探究精神及強化環境保護意識。研究目的包括探討鯨豚回聲系統與海洋環境的交互關係、其在自然因素及人為汙染影響下的變化，以及回聲系統對鯨豚生存與生態系統的核心地位。研究方法結合文獻分析與實驗設計，製作一套海洋環境模擬箱，透過磁鐵模擬回聲定位的運作過程，讓學生直觀理解回聲系統的運作原理與重要性。本研究從符號學理論出發，將鯨豚回聲定位系統與產品語構學相結合，透過設計教具傳達系統的內涵，並進一步探討自然因素如海洋酸化與溫度上升，以及人為因素如船舶噪音與能源勘探，對回聲定位系統的幹擾影響及其對鯨豚生存的威脅。本研究預期成果包括提升學生對海洋生物及其生態系統的認識，激發其對生物學和聲學的興趣，並透過實驗與互動教學，強化學生的科學素養與環境保護意識。同時，研究透過結合生物學、物理學與環境科學的跨學科教學設計，促進學生整體素養的提升。最終目標是增進學生對海洋生態保育的關注，並鼓勵未來參與自然保育行動。

The focus of this research is the significance of cetacean echolocation systems and their critical role within marine environments. The research involves developing educational materials intended for integration into elementary school curricula, aiming to enhance students' understanding of marine life, foster scientific inquiry, and strengthen environmental awareness. The objectives of the research include exploring the interaction between cetacean echolocation systems and marine environments, examining how these systems change due to natural factors and anthropogenic pollution, and highlighting the central role echolocation plays in cetacean survival and ecosystems. The research methodology combines literature review with experimental design, including the creation of a marine environment simulation box. This box utilizes magnets to simulate the echolocation process, helping students intuitively grasp the operational principles and significance of echolocation. Drawing upon semiotic theory and integrating it with product semantics, the educational tools are designed to effectively communicate the essence of the echolocation system. The research further investigates the disruptive effects of natural factors, such as ocean acidification and rising temperatures, and human-induced factors, such as ship noise and energy exploration, on cetacean echolocation and the associated threats to cetacean survival. Expected outcomes include improved student understanding of marine organisms and ecosystems, increased interest in biology and acoustics, and strengthened scientific literacy and environmental consciousness through interactive teaching and experiments. Moreover, by combining interdisciplinary educational approaches from biology, physics, and environmental science, the research aims to enhance students' overall competencies. The ultimate goal is to increase student engagement with marine ecological conservation and encourage active participation in future environmental conservation efforts..
