Title Improving Diagnostic Accuracy of Lung Auscultation through Interleaved Practice: A Quasi-Experimental Field Study Summary This research investigated the effectiveness of blocked and interleaved practice in diagnosing abnormal respiratory sounds. Conducted as a quasi-experimental study, it involved nursing students from two classrooms at Akdeniz University. The study took place in a whole classroom environment as part of their on-going education. Key dependent variables were students’ diagnostic accuracy, monitoring accuracy, and learning strategy beliefs. Data Description 1. Category learning judgments: • NB (Normal Bronc.), NV (Normal Ves.), CF (Crackle Fine), CC (Crackle Course), WH (Wheezing), RH (Rhonchi) # Individual judgments 0-100. • JOL: Average of monitoring judgments. 2. Diagnostic Accuracy • Q1-12 raw answers. • CF1  CC2; accuracy scores at the sound level. #Immediate test. • Test_IM: Aggregated test score for the immediate test. • NV3  WH4: accuracy scores at the sound level. # delayed test. • Test_D: Aggregated test score at the delayed test. • Effort: Anticipated effort associated with blocking and interleaving - B for blocking, I for interleaving. • Belief: Strategy beliefsv - 1: Blocking, 0 Equal, 2 Interleaving.
