introduction

The emphasis on the integrated design of "teaching learning evaluation" in the "Compulsory Education English Curriculum Standards (2022 Edition)" was discussed, emphasizing the importance of formative evaluation and pointing out the role of portfolio evaluation in recording students' writing growth, promoting teacher feedback, and students' self reflection. Meanwhile, it is pointed out that there is a lack of scientifically unified evaluation criteria in existing research, which may affect the fairness and effectiveness of portfolio evaluation. The author proposes to combine the China English Proficiency Scale (CSE) with portfolio evaluation to construct a formative assessment portfolio system for junior high school English writing based on CSE standards, in order to improve the standardization and effectiveness of evaluation and stimulate students' learning enthusiasm.

Formative evaluation and portfolio evaluation

Formative assessment is a continuous evaluation process aimed at dynamically tracking and providing feedback on learning activities, promoting student growth and progress. It emphasizes timely feedback and guidance to help students adjust their learning methods. In English writing teaching, formative assessment provides personalized feedback and optimizes teaching design by analyzing students' writing outcomes, processes, attitudes, and strategies. As a part of formative assessment, portfolio evaluation collects student works to showcase their efforts, progress, and achievements. It requires students to participate in the selection of evaluation content and standards, and includes evidence of self reflection. Teachers play a guiding role in portfolio evaluation, encouraging self-evaluation and reflection to enhance students' self-monitoring and academic performance. Portfolio evaluation can dynamically display students' learning process and help teachers assess students' development. Although there is a foundation for the application research of portfolio evaluation in English writing teaching in primary and secondary schools in China, teachers still face problems such as one-sided evaluation content and single form in implementation. A more scientific and objective evaluation system needs to be constructed to provide effective feedback.

Design of English Writing Portfolio Evaluation Based on CSE

Introduced the design of English writing portfolio evaluation based on CSE (China English Proficiency Scale). CSE is the unified standard for English learning, teaching, and assessment in China, which divides English proficiency into nine levels covering language comprehension, expression, pragmatics, knowledge, translation, and usage strategies. The Written Expression Ability Scale is an important component of CSE, which includes a General Ability Scale, Self Evaluation Scale, Sub item Ability Scale, and Written Expression Strategy Scale. This scale provides a scientific evaluation index system for English writing teaching and assessment. The study combines CSE with formative assessment and confirms its positive effect on improving students' English writing ability. However, there is limited research on the application of CSE in portfolio evaluation. This study combines the CSE evaluation system with the portfolio evaluation framework to provide reference standards for the evaluation of junior high school English writing portfolios. This framework includes planning and evaluating intentions, determining teaching objectives, matching teaching objectives and tasks, establishing evaluation criteria, determining the organizational structure of the portfolio, monitoring the portfolio process, and evaluating the portfolio process. The study proposes a portfolio evaluation framework based on CSE, aimed at providing teachers with clear operational procedures and standardized evaluation indicators, enhancing the operability, objectivity, and consistency of evaluation. Through case analysis, demonstrate the practical application effect of the framework, and help teachers understand and implement portfolio evaluation.

case analysis

This chapter explores the application of formative assessment based on portfolio in middle school English writing teaching through case analysis. The teaching materials are selected from the 8th and 9th grade volumes of the Foreign Language Research Press's English textbook, covering the theme group of "Literature, Art, and Sports" under the theme of "People and Society". The writing classroom task is divided into three stages: the teacher teaches the framework and methods of summary writing, students practice summary writing, peer essay evaluation, and improves writing based on feedback. Student works, peer and teacher feedback, self reflection, etc. are collected in a personal portfolio. The purpose of the evaluation is to assess students' summary writing performance, test their writing ability, and expect them to reach the CSE Level 4 level. The teaching objectives include understanding and applying summary writing structures, writing clear summaries, and effectively evaluating peer works. Teaching task design includes completing the outline writing framework, mastering functional sentence patterns, and integrating story elements to generate a summary. The evaluation criteria refer to CSE and evaluate peer essays from three dimensions: content, language, and coherence. Teachers provide personalized feedback to help students clarify their writing strengths and weaknesses. The organizational structure of the portfolio includes student works, peer evaluations, teacher feedback, and self reflection. The storage method of archive bags can be electronic or paper, and teachers need to plan the data collection process. Teachers monitor the progress of the portfolio through various means, including checking essays, class activities, group discussions, etc. At the end of the course, a comprehensive evaluation of the effectiveness of the portfolio will be conducted, including the improvement of students' writing ability, composition quality, and the effectiveness of teacher feedback, and student opinions will be collected for improvement.

conclusion

This study integrates CSE and portfolio evaluation framework to construct a formative evaluation system for junior high school English writing, which improves the effectiveness and standardization of evaluation, promotes students' self diagnosis and improvement, and enhances their writing ability. It is suggested that future research explore the application of CSE in reading, listening, and speaking teaching, as well as the combination of information technology and portfolio evaluation, in order to meet the diverse needs of students and promote innovation in English teaching.
