Final answer:
The teacher is conducting a formative assessment by collecting reading records and rubric-scored writing samples to track student progress and provide feedback that can improve teaching and learning outcomes over time.
Step-by-step explanation:
The teacher's purpose for collecting reading records and rubric-scored writing samples over time is best described as conducting a formative assessment. Formative assessments are tools that educators use to monitor student learning progress, providing feedback that can be used to improve teaching and learning. These assessments are not typically for grading but are mainly used to inform both teaching and learning processes. In this specific case, the teacher is using the collected information to document change over time, which can help identify areas where students are improving or may require additional support.
Through the formative assessment process, the teacher can observe a student’s development in reading ability and writing proficiency. Additionally, by employing a rubric, the teacher sets clear criteria for evaluating the written work which helps in maintaining consistent and objective scoring. This process aids not only in tracking a student's improvement but also serves as a guideline for students to understand the key components of successful reading and writing assignments. Over time, this practice can significantly contribute to a student's overall academic growth in language arts.
