introduction

Introduced the new requirements for teaching evaluation in the "Yijiao Curriculum Standards" and emphasized the importance of teachers' evaluation literacy. It is pointed out that the current evaluation literacy of foreign language teachers is generally low, and there is insufficient research on evaluation literacy in classroom language teaching. Diagnostic assessment, as an effective way to enhance teachers' evaluation literacy, helps teachers make more targeted teaching decisions. This study explores the development process of classroom evaluation literacy of a middle school English teacher in practice based on an online English diagnostic assessment platform through case analysis.

Classroom evaluation literacy

In depth exploration of the importance of classroom evaluation literacy in junior high school English teaching, analysis of the relationship and differences between formative evaluation and classroom evaluation, and pointing out that the academic community has not yet clearly defined the concepts of the two. Through literature review, three core elements of teachers' classroom evaluation literacy have been summarized: knowledge, concepts, and practice. At the same time, the definition of classroom evaluation literacy proposed by Carless et al. and Gu, as well as the teacher evaluation literacy framework TALiP constructed by Xu u0026 Brown, were introduced, providing theoretical support and practical guidance for improving teachers' classroom evaluation literacy.

research design

Introduced the research design, including research questions, subjects, tools, data collection and analysis methods. The research question focuses on how Teacher C implements classroom evaluation and changes in evaluation literacy based on an online diagnostic platform. The research subject is Teacher C, a new seventh grade teacher at a middle school in W city, using the U-Dig online diagnostic assessment system. The data collection lasted for one year, including diagnostic assessment results, teaching reflections, classroom videos, observations, and semi-structured interviews. Analyze the changes in the elements of C teacher's evaluation literacy through coding, frequency statistics, and topic classification.

research process

Detailed description of how Teacher C locates learning situation through diagnostic assessment, and designs and adjusts teaching activities based on the diagnostic results to promote the development of classroom evaluation literacy among middle school English teachers. In October 2022, Teacher C discovered through an online writing test that students had problems with grammar application and focused on training their grammar micro skills accordingly. In the initial teaching design, Teacher C faced challenges of insufficient time and excessive activities, resulting in teaching objectives deviating from the theme and ineffective implementation of classroom evaluation. Through reflection and adjustment, Teacher C has redefined the teaching objectives based on the overall unit, deepened the analysis of learning situations, and optimized the design of teaching activities.

Research has found that

The development of C teacher's classroom evaluation literacy after diagnostic assessment was analyzed through interviews and classroom videos. Teacher C has improved in classroom evaluation knowledge and is able to combine diagnostic results with teaching suggestions, but still feels inadequate in the practical application of specific teaching evaluation methods. Teacher C believes that classroom evaluation training content is abstract and difficult to apply in practice, and requires more specialized and easy to operate training. In terms of classroom evaluation concepts, Teacher C has begun to attach importance to diagnostic assessment results, recognize the correct classroom evaluation methods, and place greater emphasis on feedback and student output. Teacher C has developed his own evaluation preferences, such as grasping the classroom process and rhythm through teacher led classroom evaluations. In terms of classroom evaluation practice, Teacher C designs teaching activities and evaluations that match teaching objectives, and the diverse use of classroom evaluation methods and tools is particularly prominent. Teacher C has improved classroom fluency, the speed and quality of immediate feedback to students, and the control of classroom time, effectively training students' weaknesses and deepening their understanding of unit content, reflecting the promoting effect of diagnostic assessment results on teachers' classroom evaluation practice.

conclusion

The importance of classroom evaluation in improving teaching efficiency was emphasized, and through case analysis, how diagnostic assessment can promote teachers' improvement in evaluation knowledge, concepts, and practices was demonstrated. Research has found that teachers can accurately locate learning situations through diagnostic assessments, adjust teaching and evaluation in a targeted manner, effectively train students' weaknesses, and improve their classroom evaluation literacy. However, it is pointed out that teachers' knowledge growth in classroom evaluation is not significant, and more professional and actionable training is needed. There are also shortcomings in the research, and in the future, we will further explore the connection between diagnostic assessment and teachers' classroom evaluation literacy.
