ofinstructions before the implementation of the didactic methodology. Blue dots indicate students’ actual perception and orange dots indicate ideal perception of the type of instruction.Regarding the active subdimension, all six items (e, f, m, o, p, q) resulted with significantdifferences. In Figure 4, the shift of 3m to 4m indicates students’ perception of the need (in theirideal class) to preview concepts before class by reading, watching videos, etc., to solve problemsindividually during class (items 3o and 4o), or make individual presentations to the class (items(3e and 4e). These subdimensions indicate students’ willingness to active learning.Figure 5 shows the shift from actual class to ideal class corresponding to the interactive

estimate student proficiency, CDMsuse latent classes to classify students by their mastery of underlying skills [40,42,43]. Skills cutacross content areas and multiple skills may be needed to correctly solve an item. CDMs areclassification models that aim to classify a student’s skill mastery for predetermined skillsidentified by content experts (See Table 1 for definitions). The skills require to correctly answer aquestion are coded dichotomously within matrix called the Q-matrix, which is used by DCMs toestimate mastery. While there are many CDMs, the simplest is the Deterministic Inputs, Noisy"And" gate (DINA) model. DINA is a crucial cognitive diagnostic tool to effectively estimate skillmastery, such as proficiency in applying vectors in
