Development of Micro-Lectures Videos in Teaching Ecosystem for Grade 10 Students
Main Article Content
Abstract
In STEM education, studying ecosystems is also crucial to sustainable education. The Philippines environment is now facing major environmental problems with these Filipino students’ needs to develop their sense of ecological practices, this study aims to develop a micro-lecture video and learning activities. The researchers had undergone a needs assessment with the in-service science teacher aimed at gathering valuable information as a basis for crafting the developed materials. For the development of the micro-lecture videos, the researchers made use of the SAM Model. This was evaluated based on the four factors to be satisfied. Based on the evaluation results in the micro-lecture videos, the flow of energy was rated as very satisfactory of a mean (3.2425), biodiversity and stability were excellent (3.54365), and population growth and carrying capacity were Excellent (3.36115). The design learning activities were also evaluated; the content factors obtained an Excellent with a mean of (3.428), the format also obtained Excellent (3.3444), the presentation and organization obtained Excellent (3.8000), and the accuracy and up-to-datedness of information obtained an Excellent (3.7500). Hence, the development of micro-lecture videos and activities is recommended and accepted for its distribution to use as a learning material in the teaching ecosystem because this satisfies all factors that guarantee its quality. Through this study, a remarkable way to enhance the understanding of the concept of ecosystem and promote awareness of the environment.
