*** Age The program is for 3 - 8 years old *** Programming knowledge Familiarize yourself with assembling blocks of code and four basic knowledge areas in programming: Sequence - Loop - Function - Condition. Young children will learn to think according to the algorithm of computer science but also very close to common situations in life. - Basic: Children will learn how to combine blocks for robots to complete their tasks. - Sequence: Children know how to divide large jobs into small jobs, organize and perform tasks sequentially. - Loop: Children know how to use a loop when they need to repeat a task several times (a command or a group of commands) to help optimize the solution (program). - Function: Help children practice generalization and analysis skills. Know how to define and build a big task (Function) from small component jobs (commands). - Condition: Help children practice the ability to analyze, know how to streamline situations, attach conditions in each specific situation. If this condition occurs then the other action is performed. A basic knowledge of programming but also a situation that often happens in life *** Learn English through pictures - The reward when completing a task is an English card to help students get used to English naturally and excitedly - More than 400 English vocabulary cards by topics. - Standard American pronunciation. - Cute pictures, eye-catching, reminiscent. - English topics are popular with children *** Develop logical thinking With over 400 interesting levels from easy to difficult, help students practice thinking skills to optimize solutions, creative thinking, logical problem solving thinking. *** STEM JUNIOR - Excellent solution for pre-school education and first 2 years of primary school. The period of 3-7 years old is the golden stage to form and express the "I" of children. Children have the need to DEVELOP themselves independently, affirm the existence of their awareness and rights At this stage, parents need to help their children form life skills, problem-solving thinking skills in which problem-solving thinking skills are a fundamental skill, especially important as a prerequisite for most all activities in life. With STEM JUNIOR, students will have access to an interesting two-way interactive environment, helping them to express their own thinking and solutions for each situation and then immediately observe the results.

A-STEM is a mobile-based system that aims to provide educators with an efficient artificial intelligence-based assessment system. As a result, educators can quickly assess learners' creativity without any hassle and spend a lot of time on assessment procedures. The primary focus of this system is to provide an automatic assessment of learners’ creative items by using machine learning models, which experts and researchers would design. Along with this assessment mechanism, the system can also maintain educators' learner relationships, learning-to-grade, and assessment scores and provide persistent storage of all the submitted items by learners for future reference. Teachers could use the system to manage the class, provide timely feedback, and track students’ progress. The system is based upon the cloud service, which is responsible for maintaining relational information for models to items, educators to learners, and grades to learners. The system uses mobile applications as an interface. Through the system web portal, researchers will be able to upload assessment items and algorithmic machine models that can automatically score students’ responses. Teachers can create virtual classes and register students in the courses. They can organize the assessments according to the learning content and assign items to students. They could view students’ performance scores immediately once students submit their responses. Learners also have access to the system through mobile applications, and they can upload their responses to the methods for specific assessment items and retrieve scores immediately.
