The main purpose of the study is to teach high school students how to prepare their Start-Up projects in accordance with modern requirements. Through the design thinking algorithm, you can develop the skills of preparing a startup project. In the empathy stage, teams were formed among the students, in the analysis and synthesis section, each team identified a problem that needs to be solved in the future, and in the third stage of design thinking, each group identified ways to solve the problem and started preparing a prototype (MVP). During the tests of the created prototype, the teams were able to find a timely solution to the identified obstacles. And in the last stage, each startup team presented their products at a fair held inside the school and received feedback from the audience. As a result, each team participates in various competitions and presents its products in the direction of a business idea.

The main goal of the research work is to use the thinking design algorithm to guide students in grades 9-11 to develop technological startup projects, identify the obstacles encountered and offer solutions.

Research questions:

- What do startup projects teach students in grades 9-11?

- What are the obstacles to improving the project and what actions have been taken to eliminate them?

- What is the effectiveness of the thinking design algorithm in developing technological startup projects for students?

In order not to lose motivation and interest in learning, it is important for teachers not only to conduct interesting lessons, but also to lead them to research projects. In order to implement modern business ideas, students ' desire to engage in startup projects is developing rapidly. In the process of developing startup projects, students develop skills of communicative, constructive thinking, problem solving through the accumulation and analysis of information. Therefore, in this study, an algorithm for thinking design was selected to train students to engage in startup work. D. Kelly states that thinking design relies on the natural ability to be intuitive, find patterns, and come up with ideas that are not only emotionally attractive but functional, so thinking design is an effective tool for developing creativity and skill [1]. The design of thinking is based on the ability of a person to feel intuitively, to create ideas that have not only a functional, but also an emotional component [2]. Thinking design is good for everyone because it goes beyond simple things, stereotypes, and patterns to solve and, as a result, helps open up new paths, opportunities [3]. Using 6 stages of the thinking design algorithm in the development of technological startup projects, you can hone students ' love for the complex and creative skills.

Methods of startup development. A startup is a way to test new product ideas with real customers and constantly adjust the business model to get started. In 2011, Eric Rees proposed the Lean Startup approach in his book business from scratch [4].

Three startup teams of three students participated in this research work with different topics. One group studied and prepared their technology startup project for two years, the other two groups developed it for a year and presented the results to competitions of different levels. Three research methods were selected for this study: interviewing students, monitoring the process of creating a startup project, and analyzing the rational and irrational aspects of each group's project [5]. The questions of interviews with students were aimed at obtaining information about the rational points of the thinking design method in the preparation of students ' startup projects and the difficulties that occurred during the process and their solution. And the development of students ' technological startup projects was controlled using a thought design algorithm. It was based on interviewing members of the group and analyzing the project, developing students ' critical thinking skills, communication skills, and information collection and analysis found in startup projects. The development of these skills was aimed at students ' positive results in competitions using the thought design algorithm selected during the analysis of the study. During the project control, the difficulties identified in testing the prototype (MVP) at the sixth stage of thinking design were analyzed and the rational aspects of the project were proposed solutions to the difficulties [6]. These selected methods can be used at the beginning of the process of preparing startup projects, in the middle, and in the final sections of the study to achieve results, helping to assess the growth of students ' research skills.

At the initial stage of empathy, students ' shared interests in the field of technology were identified and teams were formed depending on the project directions. Since it is important to identify the problem, as Williamson said in his 2015 study of starting and running start-up projects, as a result of Interview Questions aimed at identifying the problems, the consistency of the preparatory process of students in the design of the project, ways to make improvements to the project through the analysis of new information, and the strengthening of a cooperative environment between students were identified as rational points of this method [7]. Research environment in the process of monitoring the team activities of students, the third stage of thought design was the presentation of ideas aimed at solving the problem by team members. In an interview, students noted that with the help of an algorithm of thinking design, students were rational in identifying the problem that motivated their business ideas, determining the consistency and role of each team member in proposing solutions, and contributing to the formation of a system in dealing with research. At the stage of prototyping, we distributed tasks according to the abilities of each student and monitored the timely completion of the work. During the testing of the created prototype, problems were identified in each team, for example, in the startup project "Blind Klavish" for blind people, created by a team of 11th grade students, the size of the prototype was too large to cause problems in use. We decided to reduce the size of the keyboard by conducting an analysis. At the final stage of thought design, students used their communication skills to defend their projects, defended them in a limited time, and each group achieved the desired result.
