Which of the following is used to record students’ problem solving ability, measurement ability and experimentation ability ?

The correct option is Anecdotal Record.

Explanation:

An Anecdotal Record is a detailed, qualitative report recorded by teachers that documents specific observations of a student's behavior, skills, and performance over time. Unlike basic numerical grading systems or administrative logs, anecdotal records provide contextual descriptions of how a student approaches tasks, including their problem-solving processes, practical measurement skills, and experimentation abilities during hands-on activities.

Why other options are incorrect:

• Teacher Diary: Used primarily by teachers for personal reflection, daily lesson planning, and self-assessment rather than systematic, individual student assessment.

• Cumulative Record: Contains comprehensive historical and administrative data of a student (such as academic history, attendance, health records, and general test scores) rather than qualitative observational details of specific practical skills.

• Report Card: Provides a summarized periodic evaluation (marks/grades) of academic subjects and overall performance, lacking the qualitative step-by-step documentation of experimental and problem-solving behaviors.
