Accepted: May 18, 2022. Published: May 30, 2022 Abstract: This research aims to produce quality physics learning tools using the Problem Based Learning (PBL) learning model. The study was conducted at a public senior high school (SMA Negeri 1 Tapa), Gorontalo, Indonesia. The device was developed using the 4D development model developed by Thiagarajan and Semel. The research results on the device show that the developed device is of high quality. Learning tools are said to be valid for use with little revision. It can be seen based on the average validation results of 3.5 to 3.6. The effectiveness of learning devices is seen in the increase in student learning outcomes. It consists of the cognitive domain from the first meeting until the second meeting. It obtained N Gain 0.54 with N Gain criteria moderate, in the attitude domain with an average percentage of 81.77%. The results of observing student activities during two meetings: 71.80% with good criteria. The psychomotor aspects with an average percentage of 80.36%, and the practicality of the developed devices seen from the observation sheet on the implementation of learning 84.78%, as well as teacher response questionnaires and student response questionnaires with an average the percentage of 79.88% and 84.80% got a positive response. There is an influence on student learning outcomes after the problem-based learning model is set with the help of the google meet application on parabolic motion material in the development of learning devices.

This virus has attacked 215 countries around the world. This virus is called COVID-19 or Coronavirus-19, which attacks the respiratory system in humans with symptoms of acute respiratory distress, fever, cough, and shortness of breath. The World Health Organization declared a public health emergency caused by the virus on the 30th. The status of the Covid-19 pandemic has affected almost all aspects of human life. To break the chain of virus transmission, the Indonesian government, especially the Gorontalo government, has adopted many restrictive measures. Education is one of the sectors affected by this pandemic. The Ministry of Education and Culture has not allowed local governments to open schools outside the yellow and green areas. To fulfill the rights of students to obtain educational services and learning resources that are not limited by time and place. Therefore, it is hoped that this online learning activity can support the distance learning process and facilitate the distribution of material to students. Therefore, the learning process usually carried out face-to-face with teachers and friends at school is not carried out during this pandemic. Online learning can be used as a solution for distance learning when a natural disaster occurs, as is happening now when the government establishes a social distancing policy. The government implements social distancing to limit human interaction and prevent people from crowding to avoid spreading the Covid-19 virus [1]. The development of learning tools is one way that can be used to optimize the learning process by selecting methods, models, and designs that can increase student interest and motivation so that it can have a major impact on student learning outcomes [2]. Learning tools needed to manage the learning process include the syllabus, Lesson plan, teaching materials, student activity sheets, evaluation instruments or learning outcomes tests, learning media, and student textbooks. Learning devices are several materials, tools, and media are instructions and guidelines used in the learning process [3]. The syllabus is a learning plan that includes competency standards, basic competencies, materials, learning activities, indicators, competency achievement for assessment, time allocation, and learning resources [4]. The lesson plan is a guide for teaching activities in learning activities and a description of student activities. The lesson plans were translated from the syllabus to direct student learning activities to achieve basic competence [5]. The National Education System stated in chapter 1, paragraph 1, article (20), "Learning is a process of interaction of students with educators and learning resources in a learning environment [6]. Teaching materials are materials that students must learn to achieve competency standards and basic competencies [7]. Student activity sheets are one of the learning resources that the teacher can develop as a facilitator in learning activities. Student activity sheets become learning and learning media
