Introduction
Education is a learning and learning activity that gathers and includes closely related components, and education can determine the development and progress [1], [2].Students can develop their potential through an integrated learning process.Learning as a process is a component in improving the learning process of interacting [3], [4].Media can facilitate the learning process and help teachers and students easily understand learning [5], [6].One of the components in the process is teaching materials.Teaching materials developed by teachers must contribute and effectively make students more active in learning and improve learning outcomes [7], [8].According to Joseline M. Santos [9], teachers are expected to prepare learning materials that will be delivered to students efficiently in a short time but containing the core in the learning presented [10].
Teaching materials that students can use in learning independently is one of the modules [11].According to N. Umamah [12], a complete and systematically prepared learning resource contains learning materials and guides to support or support the learning process to achieve the objectives in This study aims to (1) know the process of creating e-module-based learning media on energy materials and their changes in Nearpod applications for elementary students, (2) know the feasibility of energy learning e-module media products and their changes to the Nearpod application for elementary school students who are eligible for use in Natural Science learning.This study uses a Research and Development (R&D) model.Based on preliminary studies, there is still a lack of interactive learning media based on technology to support and increase the enthusiasm of students' learning.A learning media is needed that can help teachers and students with learning activities.This research is based on previous preliminary studies that have been carried out the learning process.This is because learning with the help of innovative media and a suitable learning model can increase students' learning interest and thinking to influence students' learning achievements [13], [14].The module designed is an effort of educators who involve learners to learn independently.This module contains at least the main components of the teaching materials source.Teaching materials are systematically arranged with language that learners can easily understand according to their level of knowledge and class age.They can learn independently, and then students can measure their level of mastery of the material discussed in each module unit.Modules are referred to as a medium for self-learning because they have been equipped with instructions for learning without teachers directly [15].
According to Rahmatsyah [16], Electronic module or e-module were defined as a learning media that contains various components that can support the learning process, namely the presence of text, images, graphics, audio, animation, and video learning that can be accessed in the computer in the learning process.Students can learn independently with their abilities and speed to complete the module package quickly and self-learning through the module [17].On the contrary, while students are slow to learn, they will also be slow to complete the lesson.Materials packaged in a more practical form in modules allow students to learn faster or slower according to their abilities [18].So that this electronic module is compiled and presented through technology media, and students can learn independently without the help of a teacher.Therefore, the utilization of technology is expected, especially the application of learning media in schools.Learning media can provide encouragement, desire, motivation, and stimuli in the learning process and psychologically impact students [19].
Nearpod is a web-based learning application that facilitates and controls interactivities during the learning experience settings [20].Furthermore, students need to have more opportunities to collaborate and be active in learning [21].Mattar [22] Shows that one of the main advantages of using Nearpod is to support student learning activities more actively in class with the various types of features that Nearpod provides to engage students in class.Therefore, Nearpod is considered one of the solutions that can improve student interaction, actively participate in the classroom, and support learning resources and be accessible on smartphones, tablets, and laptops [23].Based on the results of preliminary studies that have been conducted through field study activities by conducting observations or direct surveys and through interview activities to analyze the needs of interactive learning media development, teachers are still minor variation in the development of interactive learning media and limited development of technology-based learning media in the science learning process [24].The analysis results were compiled by 14 grade III and IV teachers from 9 different elementary schools in the 2020-2021 school year.From the results of the background exposure, this study aims to conduct a feasibility test of a research product developed not to assess the effectiveness of e-module-based media products.Therefore, this study wanted to develop a Nearpod-based module on science material "Energy and Its Changes" to improve the learning achievements of elementary school students.

Method
The type of method used in this study is using research and development (R&D) methods [25].The research and development method is applied by educators to create a specific learning product and test the success and feasibility of the learning product [26].This research was conducted from March 17, 2021, -June 5, 2021.The selection of samples of respondents in this study was conducted at SDN 1 Tukak Sadai and SDN 2 Tukak Sadai in the even semester of 2020/2021.The number of respondents from SDN 1 Tukak Sadai and SDN 2 Tukak Sadai amounted to 46 students consisting of 19 female and 27 male students.Data collection techniques and procedures in this study used a questionnaire or an assessment questionnaire using Google Form to learn media on energy materials and their changes to students at SDN 1 Tukak Sadai and SDN 2 Tukak Sadai [27].The development procedure in this study uses the selected model, namely the ADDIE development model, as for the stages in developing e Nearpod-based modules [28], see Fig. 1.
The techniques and procedures for data collection in this study used questionnaires or assessment questionnaires on learning media on energy materials and their changes in students at SDN 1 Tukak Sadai and SDN 2 Tukak Sadai.This questionnaire uses a Likert scale that is a five-scale questionnaire sheet [29].Alternative answers are 5 with categories of Highly Agree/Very Valid (HA), Agree/Valid (A), Less Agree/Less Valid (LA), Disagree/Invalid (D), and Strongly Disagree (SD).How to fill out this questionnaire sheet is with a checkmark in one of the alternative columns of answers that best suits the student's choice (respondent).As for scoring the respondent's answer is if the respondent answered Strongly Agree / Very Valid (SA) was given a score of 5, Agree / Valid (A) was given a score of 4, Less Agree / Less Valid (LA) was given a score of 3, Disagree / Invalid (D) was given a score of 2, and Strongly Disagreed (SD) was given a score of [30] (see Table 1).The questionnaire method is used to test the validity of products in E Development Nearpod-Based Module on Science Material "Energy and Its Changes" To Improve Learning Achievement of Elementary School Students.The questionnaire method is used by data collection techniques conducted by giving respondents several questions or written statements to be answered [31].The percentage is a way to express numbers as part of the whole, where the whole is written as 100%.Obtained equation, Percentage = (Sum of Parts/Total Sum) x 100%.

1) Nearpod-based e-module assessment after being tested by media experts, material experts, and feasibility tests for teachers and students
This development research produces products in the form of teaching materials e Nearpod-based IPA modules equipped with various features, including Instructions, Table of  This module e is developed using the ADDIE model, which consists of 5 stages (Fig. 1), including the analysis stage, design stage, development stage, implementation stage, and evaluation stage.The first stage is the analysis stage.This stage of the analysis is done to obtain the results of identification of initial needs data from teachers and students through interviews that have been conducted by researchers about learning activities using e neared-based modules.The learning environment can include learning culture in schools, learning culture in the classroom, educator interaction with students and student interaction with students, the potential involvement of students in the learning process, availability of learning resources, availability of information technology, and other supporting facilities [32].Then the next stage of this analysis is to focus on the learning materials selected for media creation.Moreover, researchers choose the energy and change materials by adjusting the needs of teachers and students.
The second stage is the design stage.This stage of design is done in the development of e nearedbased modules for designing.The design phase includes creating a flowchart design, storyboard, e module concept map, e module framework, learning materials, game quiz questions, and evaluation questions.The third stage is development.At this stage, creating media is done by adjusting to the stage of the storyboard that has been designed.At this stage, the media that has been completed is created and validated by media experts and material experts to be used in the learning process.At this stage of development is done to collect materials or materials teaching materials, while the material is obtained from science textbooks class IV and other books relevant to the material raised in the emodule.
The fourth stage is the implementation stage.At this stage of implementation is done first test media experts and expert test material by validators.The goal is to find out the results of validation by media experts and material experts.Implementation results in the form of validation conducted by media and material experts.This implementation stage was conducted with 46 grade IV students consisting of 2 schools, namely SDN 1 Tukak Sadai and SDN 2 Tukak Sadai found that the use of learning media integrated with the text, images, animation, audio, and video effectively increases motivation, making it easier for students to understand the material concept [33].The fifth stage is the evaluation stage.After the trial, this evaluation stage is evaluated to the validity and feasibility of media experts, material experts, and teachers.Because of the validation results from media experts, materials, and teachers, many criticisms, suggestions, and inputs on the products.Therefore, before conducting actual product trials to the research, learners must resolve all aspects of deficiencies that have been assessed by media experts, materials, and teachers.From this evaluation stage has been completed, researchers began to research by conducting product trials on 46 samples of students consisting of 2 schools, namely SDN 1 Tukak Sadai and SDN 2 Tukak Sadai.
