JoeZoo contains three main features: Feedback Tool, Rubric Builder, and Grading Tool. The Feedback Tool contains different categories such as Formatting, Grammar, Mechanics, Punctuation, and Structure to help you label feedback by color and categories. Furthermore, JoeZoo offers 91 preloaded comments based on common mistakes (e.g.  In the “Grammar” category you can find: “a/an”, “Adverb Missing”, “Fewer/Less”, “Incorrect Tense”, “Incorrect Preposition”, etc). You can modify these comments according to your criteria during the feedback process. The Rubric Builder allows teachers to create rubrics to evaluate students’ written assignments. The Grading Tool is connected to the rubric and feedback tool, allowing teachers to grade students from JoeZoo. JoeZoo also includes an automatic grammar error detector feature to help teachers keep their attention on the content while providing feedback. This feature can also be used by students who want to be sure that their writing assignments have correct spelling and grammar. The name for this feature is “Check Monkey.”

JoeZoo & the SAMR Model

  • Substitution: Students receive feedback online instead of on a printed document.
  • Augmentation: Both students and teachers are able to see patterns in feedback provided, allowing for data-driven individual tutoring and class lesson planning.
  • Modification: With the Monkey Checker feature, students can do a grammar check before delivering their assignment to the teacher. They can assess themselves and observe their own patterns of mistakes and errors.
  • Redefinition: Students could be constantly evaluated by teachers through the formative assessment online tools that JoeZoo provides. Statistics of frequent errors could be used to inform the students and parents about focus areas for improvement.

Learning Activities

English/Language Arts: 

  • Students will work in teams to analyze their own common grammar mistakes with Monkey Checker feature to create a lesson plan with activities, techniques or advice on how to fix this the grammar in their writing.
  • Students will learn how to do a critical evaluation to their peers through the creation of Rubrics with JoeZoo.
