Summary
This study evaluates the mental workload of students in the Industrial Engineering department at University X to determine if the current practicum system is optimal. The research was motivated by observations that students experienced declining academic performance and increased fatigue, likely due to independent tasks exceeding the allocated 50 minutes per week. The authors aimed to assess whether these conditions indicated excessive mental workload through measurements of performance and fatigue. The study employed a within-subject experimental design involving nine participants from the 2014 cohort enrolled in the "Production Design and Control II" practicum. This specific course was selected based on historical data showing the lowest semester grade point averages and practicum scores. Data collection occurred at three distinct time points: immediately after the 120-minute practicum session, before report assistance, and before the final report presentation. Performance was measured using the Psychomotor Vigilance Task (PVT), which recorded reaction times via parameters including mean 1/RT, shortest 10% 1/RT, lapses, and longest 10% 1/RT. Fatigue was assessed using a Visual Analog Scale (VAS) questionnaire. Statistical analysis utilized the Friedman test to detect differences across conditions and Spearman’s rho correlation to examine the relationship between performance and fatigue, using a 10% confidence level. The results indicated that only the shortest 10% 1/RT parameter showed a statistically significant difference across the three conditions (p = 0.027). In contrast, mean 1/RT, lapses, longest 10% 1/RT, and VAS fatigue scores did not show significant changes (p > 0.1). While descriptive data suggested higher vigilance immediately after practicum and lower fatigue before presentations, these variations were not statistically significant. Furthermore, although a strong correlation existed between PVT and VAS parameters, the relationship was not statistically significant. The authors concluded that students did not experience a significant increase in mental workload throughout the practicum process. Consequently, the current system, comprising 120 minutes of laboratory activity and 50 minutes of independent tasks, is deemed optimal for achieving learning outcomes. The study suggests that the observed declines in performance and fatigue were not indicative of excessive mental burden requiring systemic changes.
