Because PCBL is an instructional learning system often mediated and managed by computer technology, it is informative to examine data from the COVID-19 pandemic-mandated conversion to remote technology or hybrid instruction. Prior to the COVID-19 pandemic, student achievement in the US and in Utah had remained stagnant. Post COVID-19, national long-term trends in reading and math are no longer stagnant; scores have dipped to historic lows with greater score decreases for lower-performing students ….
For PCBL, the “effort” includes massive financial, human resource, technological, administrative, and infrastructure changes required for full implementation….
Empirical studies of PCBL are few, and currently, there is little research that demonstrates that PCBL improves academic achievement. Further, little is known about the cost-benefit ratio of system-wide implementations of PCBL.
