Success Score

Your Success Score gives you a single number to easily track how well you are meeting your targets for Talk Time and Talk Speed. The highest possible score is 100.

Talk Time

While the context of your lesson determines how much direct instruction you will need to deliver, it is clear that students benefit from opportunities to demonstrate their learning through engagement in discussion and opportunities to articulate their understanding of what they’ve learned (Edwards & Mercer, 1987; Deese, 1984). Therefore, lowering your talk time supports deep learning and creates opportunities for your students to model and reinforce understanding of the content being taught.

A large amount of teacher talk time can cause student under-involvement, which leads to loss of concentration and reduced learning. High teacher talk time also means there may be no indication of whether your students have understood the lesson content. Further, if you dominate classroom discourse, opportunities for students to develop their skills can be limited. High levels of teacher talk in the form of monologue can lead to your students taking less responsibility for their own learning as they learn only what you decide and when. Here Professor John Hattie talks about teacher Talk Time.

Talk Speed

We all talk in different ways, but have you ever reflected on your rate of speech? Word speed impacts on the amount of information each of us is able to process, including both listening and reading comprehension (Goldstein, 1940). Most adults now communicate at more than 170 words per minute, but this is too fast for most of us to comprehend all the content that is being delivered. This is particularly true for students who are listening to their teacher in a classroom (Hull, 1985). When you look at your Average WPM, consider whether your speed suited your students and the lesson context. Here Professor John Hattie talks about Talk Speed.

 

Reading Ease and Grade Level


These analytics are based on your transcript, which considers the complexity of syntax and vocabulary demonstrated during your lesson. The sophistication of your language is important due to the impact on students in processing content. Particularly for younger learners and students from non-English speaking backgrounds, the complexity of sentence structure and vocabulary must be appropriate to their learning goals and progression over time (Farr, Jenkins & Patterson, 1951). Both the Flesch (1948) and Flesh-Kincaid (1975) models are commonly used to assess the sophistication and complexity of reading level in discourse. Read more: Flesch–Kincaid readability tests

Key Terms


The word cloud highlights the key words used in your lesson based on their frequency in the transcript. The word cloud therefore provides a snapshot of the central themes of your lesson. The frequency of each word is visually illustrated by the size of that word in the cloud. This format allows you to quickly perceive the most prominent terms used in your lesson.
