ABSTRACT There has been a recent emergence of scholarship on the use of fun in the college statistics classroom, with at least 20 modalities identified. While there have been randomized experiments that suggest that fun can enhance student achievement or attitudes in statistics, these studies have generally been limited to one particular fun modality or have not been limited to the discipline of statistics. To address the efficacy of fun items in teaching statistics, a student-randomized experiment was designed… Continue Reading →

eric.ed.gov har udgivet: In Belize, the percentage of untrained teachers (i.e. teachers with the equivalent of a high school education or less) is one of the highest in the region of Latin America and the Caribbean. In response to growing student cohorts, the increased demand for more classroom teachers has led to significant decrease in the proportion of trained teachers at both the primary and secondary levels. Fewer than 45% of teachers at primary and secondary levels are trained, whereas some countries in the region report more than 80% are trained. Perhaps as a result of the lack of training, a content test that was applied to a representative sample of teachers nationwide as part of this study design revealed important gaps in teachers’ math content knowledge. The authors hypothesized… Continue Reading →

Abstract We performed an empirical study of the perceived quality of scientific graphics produced by beginning R users in two plotting systems: the base graphics package (“base R”) and the ggplot2 add-on package. In our experiment, students taking a data science course on the Coursera platform were randomized to complete identical plotting exercises using either base R or ggplot2. This exercise involved creating two plots: one bivariate scatterplot and one plot of a multivariate relationship that necessitated using color… Continue Reading →

eric.ed.gov har udgivet: Community colleges are a large sector of postsecondary education. In 2016-2017, the United States had nearly 1,000 public 2-year postsecondary institutions (community colleges), serving almost nine million students, representing 39% of all undergraduates. The majority of entering community college students require developmental (or remedial) math. Success rates in the developmental math course sequence and college more broadly are discouragingly low. Policymakers, practitioners, and researchers alike are eagerly searching for reforms to improve success rates, but there is a dearth of causal evidence on the effectiveness of most proposed reforms. We sought to answer the following question: what effect does a modularized, computer-assisted, self-paced approach to developmental math (compared with a more “traditional” direct-instruction course alternative) have on students’ likelihood of completing the developmental math course sequence? Findings… Continue Reading →
