In this research, we compared the effectiveness of different learning platforms to provide effective online learning feedback for 7th and 8th grade physics students. One of the most difficult tasks is to test the ability of students to solve problems during online learning. Therefore, we conducted a study using the effectiveness of several of the most convenient and accessible to everyone in order to control the student's work when performing group, pair and individual work and give him effective feedback.

The importance of applying the act in feedback

Most of us think that mistakes are bad and are evidence of major failures. To maximize our academic achievement, we should ask "How can we make the most of all our mistakes?".

In modern times, the accurate functioning of feedback is a necessary condition for an effective learning process. When studying the research of scientists on this issue^[8], we identified some aspects, defined as, in particular, feedback - this is a tool that gives an idea of ​​how the learning process works, informs the teacher about the achievements and problems of students, allows you to achieve the goal and solve educational problems.

            John Hattie believes that feedback is a source of information to determine the level of student performance, to fill the cognitive potential and determine the next steps in action; In a study by Juve (2004), this creates a result between action and result.                    Dinnen (2011) suggests that feedback is a way to help the other person consider changes in their actions and learn about their impact on others

^[9]

. More precisely, feedback is a method of examining the effect and outcome of student information

^[10]

. Bill Gates - The power of feedback is enormous because this mission produces effective results. It is emphasized that effective feedback is more important than learning itself.             Scientific papers describe such characteristics of feedback as purposefulness, constructiveness, usefulness, timeliness, clarity and reliability

^[8]

.             The purpose means that feedback should be given taking into account the individual abilities and interests of students, it should increase the value and significance of self-assessment, and not reduce it

^[11]

.

• Constructiveness: in case of feedback it is necessary to express one's position on the information heard without judging the person;
• usefulness: the information provided in the feedback form should help solve problems;
• timeliness: the sooner the feedback, the better;
• clarity: this should be done in specific, unambiguous phrases;
• Reliability: the information provided by the feedback should be reliable and reflect the real situation of the case^[1].

Speaking about the features of effective feedback, one cannot fail to mention such tasks as monitoring and evaluation, stimulation, development, confirmation of the past, and the formation of responsibility in the student. Stages of behavior change - resistance, emotional anger, implementation, acceptance of a new model. We do not notice some feedback errors, for example, embellishment, taking into account the advantages of the past, combination with demand, subjectivism, negative emotional background, assumptions.

There are three ways of feedback: to determine the mood and emotional state, to the activity in the lesson, to the content of the educational material. Since we conducted the process of online learning in our school, it is necessary to check the knowledge gained by students during the lesson[3]. We used various learning platforms to determine the level of knowledge gained. More precisely, we used the https://coreapp.ai/app platform to determine how well students learned the content of the educational material. By making the tasks small, we completed them in less time during the lesson and received immediate feedback on the effective content of the lesson. On the https://coreapp.ai/app platform, you can create quizzes, put appropriate terms in place of multiple dots, complete a sentence, open questions, and create auto-answer quizzes. Also, instead of writing on traditional paper, students are more engaged in the lesson if they complete the assignment online. What is the advantage of working on this platform? What are the opportunities for teachers: • mobilize the whole group to work at the same time; • determine the level of performance of tasks by students; • allow the teacher to immediately check the student's assignment; • save time spent on checking; • to see from the monitoring in which tasks the students made mistakes, and immediately give effective feedback; • create a task bank in the future; • to complete previous tasks. DATA COLLECTION AND ANALYSIS First of all, we will copy the link to the assignment for the students. By clicking on the link, students open the platform and complete tasks. In the picture below, the teacher can keep track of the tasks completed by each student, as well as who does or does not do it. Thanks to the answers of the students, he also identifies the mistakes made and gives timely feedback. This platform also allows the teacher to identify their shortcomings during the lesson and determine what points should be addressed in the next lesson. Defects can define the stage of a lesson and effectively change teaching methods. The second method of feedback is feedback on the activities in the lesson. We used the https://app.conceptboard.com platform to provide feedback on the action during the lesson. Assignments, reports, formative evaluation work, creation of a poster are given to confirm the topic covered in the lesson. There are 100 worksheets on this board.

The effectiveness of the board for the teacher: • All students in the class can complete the task at the same time; • The teacher can control the performance of the task by each student; • Can notice mistakes made by students in time and give effective, constructive feedback; • Students will not be able to copy from each other because everyone is doing the assignments at the same time; • Tasks on the board are saved, so you can return to them at any time. The picture below shows the moment of completing the tasks given to students in grade 8 to repeat the topic "Electric field". On each sheet, the student writes his name. The picture above shows the moment students of grade 8 completed tasks on the topic "Permanent Magnet". Why is feedback important? Feedback is an important part of effective learning. This helps students understand the revised text of the topic being studied and provides clear recommendations for improving their learning. Bellon et al argue that "academic feedback is more strongly associated with academic performance than any other pedagogical behavior ... this association holds regardless of class, socioeconomic status, race, or school environment"[5]. Feedback can increase a learner's confidence, self-awareness, and motivation to learn. Effective feedback in online learning facilitates learning and promotes student progress. Timely feedback from students effectively improves the quality of education.
