This article reports on a programme in which peer-assisted learning (PAL) was combined with case-based learning (CBL) in a second-year radiologic biology unit of study. Our aim is to explore evidence of whether PAL supported the development of qualitative conceptions of learning. The programme involved students in small PAL groups preparing and…

Despite significant pressure to reform science teaching and learning in K12 schools, and a concurrent call to reform undergraduate courses, higher education science content courses have remained relatively static. Higher education science faculty have few opportunities to explore research on how people learn, examine state or national science…

This report summarizes Austin Independent School District's Title I, Part A program for 2014-2015. AISD annually receives federal NCLB Title I funds, based on the percentage of low-income students in the district's attendance zones, for the purpose of improving educational programs.

Contrary to stereotypes of proto-Athapaskan culture as simplistic and archaic, evidence points to a sophisticated web of late prehistoric Asian-Athapaskan interactions. A holistic assessment of Athapaskan migrations in the context of the transpacific Dene-Yeneseian phylum (the largest, fastest pedestrian language spread on earth) sees…

When selecting a textbook, college instructors must weigh a variety of factors. One is whether the text is written at a level that is accessible to one's students. An important factor in this is how many technical words are used. I developed an index to calculate logodiversity, a term I coined that reflects the number of technical words and the…

Send your pupils into the autumn term half-term holiday with a task that requires them to explore more about the biology associated with Halloween. This article offers a fun approach, with a pub quiz format based on bats, skeletons, pumpkins and witches, that is suitable for lessons following the end-of-topic test, for STEM clubs or for PTA…

Stimulated in large part by the advent of the Internet, research productivity in many academic disciplines has changed dramatically over the last two decades. However, the assessment system that governs professional success has not kept pace, creating a mismatch between modes of scholarly productivity and academic assessment criteria. In this…

From an applied behavior-analytic perspective, aggression in people with intellectual disabilities is mostly maintained by social reinforcement consequences. However, nonsocial consequences have also been identified in functional assessments on aggression. Behaviors producing their own reinforcement have been labeled "automatic" or "nonsocial" in…

We estimate the parameters present in several differential equation models of population growth, specifically logistic growth models and two-species competition models. We discuss student-evolved strategies and offer "Mathematica" code for a gradient search approach. We use historical (1930s) data from microbial studies of the Russian biologist,…

Purpose: To provide an overview of the methodologies involved in the field of hair cell regeneration. First, the author provides a tutorial on the biotechnological foundations of this field to assist the reader in the comprehension and interpretation of the research involved in hair cell regeneration. Next, the author presents a review of stem…

Diverse biological data may be used to create illustrations of molecules in their cellular context. This report describes the scientific results that support an illustration of a eukaryotic cell, enlarged by one million times to show the distribution and arrangement of macromolecules. The panoramic cross section includes eight panels that extend…

To test the claim that digital learning tools enhance the acquisition of visual literacy in this generation of biology students, a learning intervention was carried out with 33 students enrolled in an introductory college biology course. This study compared learning outcomes following two types of learning tools: a traditional drawing activity, or…

In Germany, science education standards for students at the end of grade nine have been in existance since 2005. Some of these standards are dedicated to scientific inquiry (e.g. experimentation). They describe which abilities learners are expected to possess at the end of grade nine. In the USA, several documents describe standards for…

Traditional lecturing has been shown again and again to be a less effective teaching method regarding student engagement and promotion in the sciences. Studies that compare different teaching methods often face limitations because, over time, courses are either substantially changed and/or are taught by different instructors. This article presents…

As interdisciplinary courses are developed, instructors and researchers have to grapple with questions of how students should make connections across disciplines. We explore the issue of interdisciplinary reconciliation (IDR): how students reconcile seemingly contradictory ideas from different disciplines. While IDR has elements in common with…
