Analysis of eye tracking in math video classes
The results of the International Student Assessment Program (Pisa) carried out in 2018, indicate that about 68.1% of Brazilian students have a mathematical mastery below the minimum level for exercising their citizenship. Considering the lower-than-expected performance in mathematics, especially in high school, a reflection on the planning of a teaching procedure in high school was proposed. Thus, the objective of the research is to verify the feasibility of using eye tracking as part of the evaluation of bilingual math video lessons (Libras/Portuguese). With specific objectives to analyze the correlation between attention retention (number and fixation time) and mathematical learning from the content displayed multimodally in video classes. To this end, we used an exploratory research methodology with a multiple base design between video lessons/mathematical concept, taking as a trigger, the math video lessons produced by the preparatory school of the Federal University of ABC (UFABC). Ocular measurements were collected using the Tobii 3C device. To this end, we divided our research into five stages, namely: 1) literature review; 2) development of the protocol for collecting and delimiting our available equipment; 3) selection of 11 participants for characterization, using the Reasoning Test Battery (BPR-5) and questionnaires; 4) teaching procedure consisting of an initial survey in the format of fixing exercises and contextualized problems, video lessons on the concepts of multiplication, distributive, greatest common divisor and least common divisor, finally, the reapplication of the initial exercises; 5) treatment and discussion of results, considering successes, errors, characterization, fixation time, saccadic movements, number of fixations and Pisa parameters. We obtained, in a preliminary way, that this proposed procedure contributed to the learning of the participants, revealing a positive impact of the intervention that lasted an average of two hours, since the presentation of an acquisition of the concepts, even if in an initial way. We can also infer that when we cross the performance and its feedback with the eye tracking, it is possible to identify, and especially to differentiate, the educational problems, evidencing positive and negative points of the visual resource, in addition to the learning gaps of the participants. It can then act as a support to the evaluation processes of educators.
