Computer grading is the process of marking and scoring exam papers using computer software. Below is a general procedure for computer grading operations:
Scan Exams: Convert paper exams to electronic format using a scanner or camera device. Ensure the scanned images are clear and legible.
2. Import Exams: Open the grading software, select the import or batch import feature. Import the scanned exam images into the software, ensuring the correct order of the images.
3. Calibration and Recognition: The software performs image calibration and recognition to ensure that the layout and position of questions on the exam papers are correctly identified. It automatically recognizes the questions and options on the exam papers and marks them accordingly.
4. Answer Scoring: Scores are assigned based on pre-set criteria. For objective questions (such as multiple-choice and fill-in-the-blanks), the software can compare the student's answers to the pre-set answers and automatically provide scores. For subjective questions (such as essay questions), the software can offer scoring guidelines, but the actual scoring requires manual operation by teachers.
5. Manual Verification: After the automatic scoring is completed, you can manually verify the scoring results to ensure accuracy and consistency.
6. Report Generation: Scoring software typically offers a report generation feature. Various types of statistics, grade reports, or scoring documents can be generated as needed.
Please note that the specific procedures for computer grading may vary depending on the grading software used. It is recommended that you consult the user manual or related operation guides of the specific grading software before use to obtain more detailed and accurate instructions.
Additionally, computerized grading may have certain requirements regarding the layout, types of questions, and response methods on the exam papers. To ensure the accuracy and feasibility of grading, it is recommended to consider these requirements when creating the exam and to consult with relevant educational technology support personnel before using computerized grading.
