    Study Notes

    Rubric for Deadlines A-D

    • Grading Rubric: This document outlines criteria for scoring tasks related to deadlines A through D. Each deadline has different sections (e.g., "Detailed Inputs," "Detailed Outputs," "Detailed Workflow") with varying point values and associated criteria.

    Task Specific Grading Criteria

    • Exemplary: All criteria are met accurately and completely. Specific details depend on the task. For example:
      • Code for Task 1: All data loads and appropriate data validations are completed correctly;
      • Code for Task 2: All inputs and data validations are programmed correctly;
      • Code for Task 3: Enthalpies calculated correctly, including interpolation as needed.
    • Above Average: Almost all criteria are met, with minor omissions or inaccuracies. Example:
      • Code for Task 1: Appropriate data loads but one or two data validations are missing or slightly incorrect.
    • Developing: Many criteria are not met or contain significant mistakes. Examples:
      • Code for Task 1: Data not loaded correctly, more than two data validations missing or incorrect.
      • Code for Task 2: Missing multiple inputs or data validations or if done incorrectly
    • Score: Numerical grade given based on the rubric's criteria for each task.

    Specific Task Breakdown

    • Section: Identifies the specific part of the task or deadline being evaluated (e.g., "Detailed Inputs," "Results CSV File," "Compressor Work Output")
    • Total Points: Maximum possible points for that section.
    • Criteria: Explains what an exemplary, above-average, developing, and failing submission should contain or lack. Different results are expected for each section. Units, complete calculations, data loading accuracy, and logical algorithms are key factors.
