PM-KIMEN 24A: A dataset for analyzing EEG-based concentration and performance in gamified learning environments

It supports interdisciplinary research in neuroeducation, gamification, and educational technology. The database includes the following variables: General Identifiers: ● User: Unique numerical identifier for each participant, ranging from 1 to 14. ● Session: Unique text identifier for each session in the format "SN" (e.g., S1, S2, S3). ● Timestamp: Date and time of data collection in the format "yyyy/mm/dd HH:MM". ● Time: Elapsed time during each task, recorded in "HH:MM:SS".

EEG and Brainwave Data: ● RAW_TP9, RAW_AF7, RAW_AF8, RAW_TP10: Raw EEG data in microvolts recorded at specific sensor locations (TP9, AF7, AF8, TP10). ● RazonTP9(B/T), RazonAF7(B/T), RazonAF8(B/T), RazonTP10(B/T): Ratios of beta to theta brainwave bands for each sensor location, reflecting concentration levels. ● X_Delta, X_Theta, X_Alpha, X_Beta, X_Gamma, X_Razon(B/T): Mean values of delta, theta, alpha, beta, gamma bands, and beta-to-theta ratio for each session. ● S_Delta, S_Theta, S_Alpha, S_Beta, S_Gamma, S_Razon(B/T): Standard deviations for the respective brainwave bands and ratios, providing variability measures.

Concentration Analysis: ● Peaks_Concentration: Detected outliers where concentration values exceed two standard deviations, indicating significant concentration spikes. ● Total_Peaks: Count of concentration peaks identified during the session. ● Predicts_Concentration: Concentration levels calculated using the predictive model developed by Pérez-Gómez et al. (2025), which estimates concentration through a low-cost EEG device. ● Total_Predicts: Count of predicted concentration peaks using the authors' model.

Simulator Performance Metrics (KPIs): ● KPI Plazo: Measures time management efficiency within tasks. ● KPI Costo: Evaluates resource management during simulations. ● KPI Satisfacción: Represents satisfaction levels of stakeholders involved in the simulation. ● KPI Total: Aggregates all performance metrics to provide an overall performance score.
