Encouraging Active Learning Can Improve Students' Performance on Examinations

Abstract: We tested the hypothesis that students in psychology of women classes would perform better on materials covered by multiple-choice exams when the first author presented these materials with active learning versus lecture, autonomous readings, and video presentations alone. Across 3 classes, we coded exam items according to how the instructor presented relevant materials and recorded classwide performance. Both between and within classes, students' performances were better on items testing materials covered with active learning techniques compared to other formats. These data provide empirical support for the efficacy of active learning techniques.

Asynchronous Discussions and Assessment in Online Learning

Abstract: This case study explored asynchronous online discussions, assessment processes, and the meaning students derived from their experiences in five online graduate courses at the Colleges of Education of two Midwestern higher education institutions. The findings suggest that asynchronous online discussions facilitate a multidimensional process of assessment demonstrated in the aspects of structure, self-regulatory activities, learner autonomy, learning community and student writing skills. The students valued the discussions as an essential component of their online learning. Further research is needed to understand the characteristics of online assessment, and what assessment strategies or criteria enhance assessment and learning.

Electrospun polymer nanofibres with small diameters.

Abstract: Nylon-4,6 nanofibres with diameters ranging from about 1 µm down to 1 nm were prepared by electrospinning. The fibre diameter was varied by adjusting the concentration of the polymer solution. Electrospinning of a concentrated solution of as high as 20% nylon-4,6 by weight in formic acid produced a ribbon-like electrospun fibre with a ribbon width of about 850 nm. A semi-dilute concentration of 2% nylon-4,6 by weight produced the thinnest nylon-4,6 nanofibres with diameters of 1.6 nm or less. A small amount of pyridine was added to the electrospinning solution to avoid the formation of beaded nanofibres in the course of electrospinning at low concentrations. Scanning and transmission electron microscopy were used to characterize the size of the nanofibres. An ultra-thin nylon-4,6 nanofibre of 1.2 nm diameter might contain six or seven nylon-4,6 molecules in a typical cross-section of the fibre.
