As summer approaches, many primary schools have changed their assessment methods for the learning outcomes of lower grade students, with "Le Kao" being conducted in the first and second grades. For example, Beijing primary schools create a lively garden scene, where children can use their learned knowledge to solve real problems by looking up dictionaries, reading pinyin to get tickets, and taking a boat to climb a tower; Xitakou Primary School in Shijiazhuang City, Hebei Province held a fun challenge activity with the theme of "Learning without Paper, Happy Childhood", allowing students to showcase their academic literacy through enjoyable challenges. Le Kao "is a new type of evaluation method widely promoted in China's basic education stage, especially in the lower and middle grades of primary schools. It is an innovation and reform of the traditional paper and pencil examination form, focusing more on students' comprehensive development, process evaluation, subject literacy, and comprehensive ability assessment. Le Kao "is one of the important practical forms for implementing the" Overall Plan for Deepening the Reform of Education Evaluation in the New Era "," Compulsory Education Curriculum Plan and Curriculum Standards (2022 Edition) ", and the" Double Reduction "policy. Schools should combine subject learning objectives in student evaluations, with a focus on strengthening literacy orientation and emphasizing the examination of correct values, essential character traits, and key abilities. Emphasis should be placed on cultivating students' patriotism, sense of social responsibility, innovative spirit, and practical ability, enabling them to have the ability to comprehensively apply knowledge to solve problems in real situations. Lekao emphasizes the diversification of evaluation content, overcoming the drawbacks of narrow content and only focusing on knowledge points in the past. Specifically, the evaluation content not only covers knowledge of subjects such as Chinese and mathematics, but also integrates comprehensive qualities such as sports, art, labor, scientific exploration, behavioral habits, cooperation and communication. The evaluation method of "Le Kao" is diverse, overcoming the previous single paper and pencil test evaluation method, and improving the academic evaluation system that combines process assessment and outcome assessment organically. Specifically, "Lekao" emphasizes gamification, contextualization, and comprehensive evaluation, and focuses on theme based challenge design, which integrates subject knowledge into game tasks based on familiar fairy tales and life scenes, such as "forest exploration," "supermarket shopping," and "space travel; We also attach importance to the use of performance evaluation, observing students' participation, cooperation ability, problem-solving strategies, etc. in tasks, rather than simply emphasizing the correctness of answers. For example, in mathematical tasks, more emphasis is placed on whether the problem can be solved using multiple methods, rather than whether the answer is correct. At the same time, "Le Kao" has increased the requirements for teachers' evaluation abilities, including both the design of evaluation tasks and assessment abilities. For example, how teachers design diverse game activities and expressive tasks that cater to students' interests, and how to assess non cognitive abilities; How can teachers collect evidence of students' problem-solving and systematic thinking abilities during the game process; How can teachers improve their evaluation literacy, digital literacy, etc. Currently, schools are also facing some urgent situations that need to be considered in the process of trying to take the "Le Kao" exam. For example, how to align evaluation with educational standards and curriculum learning objectives; How to design authentic and meaningful evaluations that involve students and empower them with learning autonomy; How to measure aspects that are actually valuable but not easy to quantify; How to ensure the scientificity, rigor, and fairness of evaluation methods; How to help students reflect on their learning status after the "Happy Exam", and complete a closed loop of evaluation, feedback, improvement, and re evaluation. Overall, 'Le Kao' meets both national policy requirements and the development trend of examination evaluation, and has a certain promotion foundation. Firstly, the national overall plan, new curriculum standards, and the "double reduction" policy requirements for non paper and pencil tests for lower grades in Beijing have provided solid institutional guarantees for promoting "Le Kao". Secondly, the practical model is gradually maturing and has certain replicability and promotability. Research has found that "Le Kao" is beneficial for students to enhance their learning autonomy, guide teachers to pay more attention to students' growth, and reduce parental anxiety. Thirdly, the trend of exam evaluation development presents a significant shift from paper and pen to digital tools (from paper and pen to computer), and from human led to technology empowered (from humans to machines). This means that exam evaluations will gradually reduce their reliance on paper and pen, and instead achieve more efficient, accurate, and cost-effective evaluations through computers. At the same time, the deep integration of artificial intelligence technology will also become an important development direction. Some pilot schools have attempted to use electronic growth records, classroom and extracurricular activity behavior analysis systems to record the process of "Happy Exam". In the future, more evaluation tools can be promoted through regional education platforms to ensure the scientific and objective nature of "Le Kao" and reduce the design and implementation costs of schools. We look forward to building an educational ecosystem that spans the entire chain of "teaching, learning, and evaluation" with "entertainment" as the link, leveraging teachers' teaching passion, students' learning motivation, and changes in evaluation methods with "entertainment" as the fulcrum, so that education can ultimately achieve "integrating education with entertainment and integrating evaluation with entertainment".
