Title: A Modified t-test for Treatment Means in Unreplicated Classroom Comparisons
Abstract: Discipline-based education research (DBER), with a focus on evidence-based teaching, has grown immensely over the last decades. A common interest in DBER studies is identifying superior pedagogical approaches using rigorous and scientific methodology. Researchers may have few classrooms available when comparing classroom-level treatments or conditions so that one classroom per treatment is not uncommon in many DBER studies.

Title: Some Clustering Methods for Omics Data
Abstract: The advent of high-throughput sequencing technologies has significantly facilitated omics research over the past two decades, generating a vast volume of data. Unsupervised learning technologies such as cluster analysis serve as powerful tools to uncover hidden patterns and associations in omics data. However, the intricate natural structure and unique characteristics of omics data often make generic clustering methods inefficient or unsuitable.
