There were two primary focuses of this research. The first aim was to investigate how students’ perception toward the flipped classroom and video learning correlate to their characteristics including their demographics, first generation status, English language learner status, Grit level, motivation types, quality of peer collaboration, and social self-efficacy. Our data indicated that there is significant correlation between student’s motivation status and attitude toward learning from video lectures. The intrinsically motivated students have a higher attitude toward learning from video. This study also demonstrates that participants with high Grit scores performed better than the participants with low Grit scores. The second aim was to investigate the effect of D3R activation on resonance frequency and sag amplitude in type I layer V medial prefrontal cortical pyramidal neurons. Because dopamine D3R is a relatively hot area of research, I first completed an extended literature review on D3R cellular mechanisms and roles in many neuropsychiatric diseases. Then I explored the effect of D3R agonists on type I layer V pyramidal neurons. I used two types of novel Dopamine D3R agonists in this study. I found that D3R agonist application inhibited the sag amplitude and resonance frequency in type I layer V mPFC pyramidal neurons. This work shed light on previously unknown cellular mechanisms on the effect of dopamine D3R activation on intrinsic electrical properties of type I layer V pyramidal neurons. The concentrations of both agonists used was 10 uM, at these concentrations; the drugs should saturate the D3R in our cortical slices. Further dose response experiments are needed to determine the concentration range of D3R agonists that could facilitate usage in future research.
