This guided approach makes sure conversations remain focused and relevant to the current activity. When Wittly provides explanations or poses questions, students can select from the provided responses, indicating their understanding or need for further clarification.
The student engagement workflow includes the following steps:
Wittly is called when a student needs help with a specific activity in Classworks.
Each Classworks activity focuses on a particular skill or concept, and we’ve tagged all activities with learning objectives for the specific activity.
When a student accesses Wittly, we send key pieces of information, including the student’s first name, the learning objective of the activity they’re working on, and the language preference of the student.
Wittly generates a personalized response to help the student. This typically includes a greeting using the student’s name, an explanation of the concept, an example related to the learning objective, and a prompt asking if the explanation helped the student understand the concept.
The following is a sample interaction, starting with the input sent to Wittly:
{
 “student_name”: “Alex”,
 “learning_objective”: “Identify and use proper punctuation in compound sentences”,
 “language”: “English”
}
Wittly’s output is as follows:
“Hi Alex! Let’s work on punctuating compound sentences. Remember to use a comma before coordinating conjunctions like ‘and’ or ‘but’. For example: ‘I love pizza, and I enjoy pasta.’ Do you understand this? Please reply with ‘thumbs up’ or ‘thumbs down’.”
Wittly is designed to adapt to each student’s unique needs. It can communicate in both English and Spanish, and students can choose a voice they find engaging. For those who prefer auditory learning, Wittly reads its answers aloud while highlighting the corresponding text, making the learning experience both dynamic and accessible.
