we do
Context and Motivation
How we tell stories reflects how we organize our thoughts and provides insights into our cognition. This observation comes from Dr. Natália Mota, psychiatrist and chief scientist at Mobile Brain, after over a decade of scientific research. Using graph theory - a mathematical framework that allows us to analyze narratives as a trajectory of words and their interactions - these studies revealed a relationship between the complexity of stories and individuals' education levels.
In some specific cases, for children in the early stages of literacy, there was a predictive correlation between the complexity of a child's narrative observed in the middle of the year and their reading performance at the end of the year, indicating an association between oral language and the learning of written language.
The Birth of Mobile Brain
These observations led to the establishing of a research and development area at Motrix Techknowledge - the Motrix Lab. It aimed to develop educational tools to assist schools and teachers in monitoring their students, especially after the pandemic disrupted literacy processes, leaving enduring impacts.
Thus, Mobile Brain emerged as a spin-off from Motrix Lab, with the challenge of continuing to do science and innovation in education, focusing on research and products based on scientific evidence.
how
we do it
LitMetrix
LitMetrix comprises indices derived from analyses of stories told by students. It allows for monitoring narrative complexity and predicting the decoding and reading comprehension performance of 1st and 2nd-grade elementary students. These insights, combined with the student's grade level, help identify whether their development aligns with expectations for that grade.
The results are presented in a graph similar to the growth curve monitored by pediatricians. This developmental curve represents the LitMetrix Index, displaying percentiles of narrative complexity by grade level.
benefits?
The story collection protocol is simple and playful.
Indices can be tracked throughout elementary and high school years.
Results are fast and scalable, suitable for individual schools or entire networks.
Educators and guardians can have comparisons and alerts to monitor students' cognitive development.
Based on the student's percentile, interventions can be identified to align with their cognitive development.
Education managers can track their classes and take broad and quick actions.
