Encouragement for Faculty to Implement Vision and Change.

The seminal report Vision and Change outlined improvements necessary for undergraduate biology courses to accomplish widely recognized learning objectives. Over the past 8 years, we have developed a two-semester introductory biology course that incorporates the core concepts and competencies recommended in Vision and Change Using published research on how students learn, we focused our efforts on three main areas of change: pedagogy, course content, and technology. We introduced active-learning strategies to improve our classroom environments, wrote an e-textbook that provides students with the tools they need to construct their own knowledge, and employed an online learning hub to assist students who needed extra support. The redesigned courses have been well received by students, and we have seen good student learning outcomes. The purpose of this essay is to demonstrate to faculty that Vision and Change's recommendations are feasible and students welcome the improvements.

Mitochondrial genome sequence of Sibynophis chinensis (Squamata, Colubridae).

The complete mitochondrial (mt) genome of the Chinese many-toothed snake, Sibynophis chinensis, was sequenced and found to be 17,163 bp in length. The arrangement of 13 protein-coding genes, tRNAs and rRNAs was identical to that of other common snake mt genomes. The mt protein-coding genes of S. chinensis utilized ATA, ATG, ATA and GTG as initiation codons and AGA, AGG, TAA, TAG and T as termination codons. Among three tRNA clusters (LQM, WANCY and HSL), LQM was found instead of IQM, which is common in other vertebrates. We also identified two control regions that contained several conserved elements known as conserved sequence blocks and termination-associated sequences related to mt replication and transcription.
