DEVELOPMENT OF INTERACTIVE LEARNING MEDIA BASED ON THE PROBLEM SOLVING METHOD USING PREZI FOR THE TOPIC OF ENVIRONMENTAL CHANGES

The process of learning Biology is still dominated by teachers as the sole source of information, using less interactive teaching media such as chalkboards and textbooks. The use of interactive media is considered appropriate for fostering students' problem-solving abilities, especially in the topic of Environmental Changes. The development of interactive media is crucial. This study aims to develop an interactive learning media using Prezi based on the problem-solving method for the topic of Environmental Changes. The research utilizes the R&D (Research and Development) model following the Borg and Gall research design, with the following stages: potential and problem stage, data collection stage, product design stage, design validation stage, design revision stage, and product revision stage.


INTRODUCTION
The learning process, which encompasses both the process of learning and teaching, cannot be separated from classroom activities.
Effective classroom learning activities demand collaboration between teachers and students.Teachers must strive to provide the best teaching materials.Therefore, innovation and new ideas are needed to develop the presentation of materials.The potential of an educator is seen in how they choose an appropriate method, approach, and media for conveying the material [1].
The future challenges are always changing, accompanied by increasingly intense competition.This demands educators to be not only skilled in a particular field but also capable of developing their specialized areas.Thus, it will produce students who can think creatively and critically in problem-solving [2].

RESULTS AND DISCUSSION
The

Design Revision Stage
The design revision stage is carried out to rectify the deficiencies in the instructional media product that has been designed and validated.The media is validated by experts in the field, allowing weaknesses and suggestions from the validators to be identified.These weaknesses are then research results regarding the development of instructional media using the Borg & Gall model with stages including the potential and problem stage, data collection stage, product design stage, design validation stage, design revision stage, and Nafisah Hanim, et.al.product revision stage are explained as follows: Potential and Problem Stage The development research that employs the Borg and Gall model begins with the potential and problem stage.This stage is utilized to identify the issues in schools related to the use of instructional media in the teaching and learning processes that have taken place.Research always starts with the existence of potential and problems.These issues can be addressed through R&D by investigating them, leading to the discovery of an effective model, system, or integrated approach that can be used to overcome these problems [6].The importance of the teacher's role in utilizing media can enhance students' interest, motivation, and learning outcomes.One-way learning encompasses two aspects that can lead to student passivity in learning.Therefore, it is hoped that the educator's response can foster motivation in educators regarding the significance of media utilization in teaching and learning [7].Data Collection Stage The data collection stage is carried out with the aim of gathering information through observation and interviews.The information and data obtained can be used as material to plan and create a specific product intended to address the issues [8].The results of the data collection will be used as a reference for planning the creation of instructional media products.The use of media in the Environmental Changes topic is currently limited to readings from textbooks, newspapers, or similar sources.This has resulted in passive students who have a limited understanding of the explanations about Environmental Changes, and only a fraction of the students pay attention to the teacher's explanations.The media that can be used is the interactive instructional media Prezi based on the problem-solving method.This media allows for capturing students' attention as it not only presents theories but also includes news videos about environmental changes, images, and supporting animations that can engage students, facilitate their understanding of the material, and enable them to analyze environmental issues.Prezi can shift the paradigm of learning from being teacher-centered to student-centered, where the teacher acts as a facilitator, making students more actively engaged in learning and no longer solely reliant on the teacher as the sole source of information [9].Product Design Stage The product design stage is the phase of creating instructional media aimed at designing an interactive instructional media using the Prezi platform based on the problem-solving method for the topic of Environmental Changes.The design of this instructional ) and learning indicators.This stage is carried out by designing an interactive instructional media using the Prezi platform based on the problem-solving method for the Environmental Changes topic.The main tasks include gathering materials on Environmental Changer, such as theories, news videos, and supporting theory videos from YouTube, images, and articles that align with the basic competencies and indicators.Then, selecting templates, themes, colors, and animations accessible on the prezi.comwebsite to make the designed media appealing to student.

According to the research by Diyah Ayu Setia Ningsih et al., Prezi can shift the paradigm of learning from being teacher-centered to student-centered, with the teacher acting as a facilitator, thus making students more actively engaged in learning and no longer solely relying on the teacher as the sole source of information.
