What Teachers are saying
about TA39?

What I have found with TA39, is that it can provide very detailed pertinent information on how a student can improve their writing in a timely fashion so students can iterate before handing in a final product…it can take days in normal circumstances.

The feedback on these is super specific and I think that’s extremely helpful. The detail they go into would be helpful and offer a lot of support when I use this for feedback after a rough draft because kids can see specifically what they need to work on.

Rubric Conversion Guide for TA39
Familiar as you are with rubrics, their adaptation for AI usage in TA39 requires a shift from traditional formats. Rubrics typically encapsulated in tables or images need to be translated into straightforward text. To assist with this transition, we suggest reviewing the provided example file below, which outlines a format compatible with AI tools.

Formatting Rubrics for TA39
Rubrics in TA39 are most effective when formatted as detailed, narrative text. This involves titling each criterion and providing a descriptive breakdown for each performance level, with points assigned to each. It's essential to maintain a uniform structure to aid clarity and ease of use.

Translating Tabular Rubrics into Text
To adapt your tabular rubrics for TA39, transcribe the content of each rubric cell into a textual description. Begin with the criterion, followed by performance levels detailed in full sentences or bullet points. For example, "Criterion 1: Response to Prompt" would be followed by performance descriptors ranging from "4 pts - Exceeds Expectations" to "0 pts - No Marks."

Detailing Performance Levels
When defining performance levels, include distinctive criteria for each score, covering all key aspects you evaluate during grading. This precision helps the AI to accurately assess and provide feedback according to your standards.

Utilizing Bullet Points and Lists
While TA39 accommodates bullet points and numbered lists, they must be used to clearly define each criterion within a rubric. Ensure each bullet or list item is tagged with performance descriptors such as "Exceeds" or "Meets Expectations."

Weighting Criteria
Explicitly state the weight of each criterion in your rubric text, specifying the maximum points possible. If you prioritize certain criteria, this should be reflected in the rubric, indicating the proportion of the total grade it represents.

Ensuring AI Interpretation Accuracy
Use precise, straightforward language in your rubrics to facilitate accurate AI interpretation. Clearly describe what is being assessed and how points are distributed to avoid ambiguity.

Inclusion of Examples
Incorporating examples within your rubrics is optional but can enhance clarity. If included, mark them clearly and ensure they relate directly to the assessment criteria.

Addressing Subjective Criteria
For subjective criteria, provide detailed descriptions that capture the essence of what qualifies as "good" or "excellent" in the context of your assignment, helping to quantify subjective evaluations.

Application of Rubrics to Assignments
After crafting your rubric, you must manually attach it to the corresponding assignments in TA39. The system will then use this rubric to guide the feedback generation process.

Adjusting Rubrics
Rubrics can be edited post-creation. Should you revise a rubric after grading has commenced, consider re-running the assignment analysis to ensure the feedback reflects the updated criteria. It is advisable to create a new rubric under a different name, so that you may go iterate across the versions and fine tune over time.

Getting Assistance
If you require help with rubric conversion or have specific questions, TA39's support team is readily available to provide assistance and ensure you can leverage the AI grading experience to its full potential.

Feedback Format Templates

Creating and Utilizing Feedback Templates
In TA39, feedback format templates are integral for shaping how feedback is presented to students. These templates, which teachers create within the system, dictate the feedback's tone, style, and structure. They play a crucial role in ensuring that the feedback resonates with the teacher's unique voice and teaching methodology. When creating a template, teachers can define the tone (strict, encouraging, formal), and choose the feedback's format, like paragraphs or bullet points.

Example Template
This is a generic example that works well together with the example of the rubric given above and appears as default in your account, when you first log in. You may use this as is, or make a copy to play around with tone of the feedback to see the results.

Consistency Across Assignments
One of the key advantages of these templates is the ability to use them across multiple assignments. This feature allows for a consistent feedback experience for students and saves valuable time for teachers, who can apply a well-crafted template to various assignments.

Tone and Flexibility
The tone set in these templates significantly influences how students perceive and interact with the feedback. It's essential to select a tone that aligns with the educational objectives and the teacher's personal style. While the AI in TA39 strives to adhere to the template's structure, it possesses the flexibility to tailor feedback based on individual student submissions.

Editing and Sharing
Templates can be edited and refined over time, allowing teachers to adapt them based on feedback and evolving teaching strategies. Although TA39 is currently designed for individual use, sharing effective templates among colleagues could be a feature to consider for future development.

What are the best practices for handling handwritten student submissions with TA39?

Encourage students to submit their work in a clear and legible manner, using PDF format for digital submissions when possible. Ensure all documents are properly oriented and avoid shadows or obstructions in scans or photos. This will facilitate smoother OCR processing and improve the accuracy of TA39's analysis.

What instructions should you give to students for preparing handwritten submissions for TA39?

Direct students to keep their pages clean, focusing solely on the teacher's prompt. They should avoid unnecessary decorations and scribbles, as these can confuse the AI. Emphasize the importance of legible handwriting and strict adherence to the assignment's specific requirements to ensure the submission's quality and facilitate accurate AI feedback.

How can students take clean and quality pictures of their handwritten work for TA39 submissions?

Advise students to capture their work in well-lit conditions, holding the camera directly above the document to avoid angles and distortions. They should ensure the text is readable and the entire page is visible in the photo. Recommending the use of a scanning app can also help maintain consistent quality across submissions.

How can the submission process be streamlined through LMS integration for TA39?

Instruct students to upload pictures or scanned documents of their handwritten assignments directly to the LMS (e.g., Canvas). You can then download these submissions in a zip file, containing either images or PDF versions, which can be easily uploaded to TA39 for efficient assignment setup and analysis.
