Far too few high-school students choose subjects from the natural sciences (NaSc) for their majors in many countries. Even fewer study biology, chemistry or physics at university. Those, that do, often lack training to present and discuss scientific results and ideas in texts. To meet these challenges the center for didactics of biology of Graz…

Understanding sources of performance bias in science assessment provides important insights into whether science curricula and/or assessments are valid representations of student abilities. Research investigating assessment bias due to factors such as instrument structure, participant characteristics, and item types are well documented across a…

This study marries collaborative problem solving and learning study in understanding the onset of a cycle of teacher professional development process within school-based professional learning communities (PLCs). It aimed to explore how a PLC carried out collaborative problem finding--a key process involved in collaborative problem solving--that…

This research, which was tried with 217 high school students, was carried out to determine the perceptions and attitudes related to the usage of bioenergy. The research results showed that the students had the perception that there would be lack of food due to global warming, but bioenergy would prevent the world from global warming. Moreover,…

This paper reports on a quasi-experimental study examining the effectiveness of flipped instruction in a 9th grade biology classroom. This study included four sections of freshmen-level biology taught by the first author at a private secondary school in the Pacific Northwest. Using a block randomized design, two sections were flipped and two…

We describe the development and implementation of an online graduate bioethics program that weaves a theme of health justice throughout the curriculum. Our account relies on a constructionist model of curriculum development and adult teaching and learning theory. Our curriculum draws upon core values of Jesuit higher education, including content…

Primary literature offers rich opportunities to teach students how to "think like a scientist," but the challenges students face when they attempt to read research articles are not well understood. Here, we present an analysis of what master's students perceive as the most challenging aspects of engaging with primary literature. We…

In usual understandings of learning, youths' development in classrooms is portrayed as a move from being a novice to an expert. However, findings of the present anthropologically framed study support us to argue that learning, rather, can be characterized as youths' simultaneous occupation of novice and expert roles. We refer to this simultaneous…

Long-term English learners (LTELs) are frequently characterized as struggling with academic reading in English. This paper moves beyond broad generalizations about this population's English-reading practices to a situated analysis of one "LTEL"--Lizbeth Sanchez's--making meaning in her sophomore biology classroom. This analysis of…

The author's goal in this comment is not only to build on the Salk and Hyde (2012) exhortation but also to shape it toward certain kinds of developmental/genetic theory and away from others. She has several priorities: (a) to emphasize best practices in empirically defensible, nonreductive biology, (b) to provide feminist (and other) biologists…

Current "one disease, one target and one drug" drug development paradigm is under question as relatively few drugs have reached the market in the last two decades. Increasingly research focus is being placed on the study of drug action against biological systems as a whole rather than against a single component (called "Systems…

Terrariums have decorated the shelves and counters of biology offices and classrooms for centuries. Living organisms inspire students and teachers alike. These wonderful ecosystems allow for both experimentation and observation of living systems. Here, I outline a new approach to building classroom terrariums. Historically, terrariums have been…

We investigated the understanding of causal systems categories--categories defined by common causal structure rather than by common domain content--among college students. We asked students who were either novices or experts in the physical sciences to sort descriptions of real-world phenomena that varied in their causal structure (e.g., negative…

A goal of most environmental education is to motivate students toward environmentally friendly behaviour change. This article describes a study that elucidates how such motivation can be fostered in the classroom. It compared students' development of environmental motivation in a conventional post-secondary environmental biology course and a…

Ayurveda, the native healthcare system of India, is a rich resource of well-documented ancient medical knowledge. Although the roots of this knowledge date back to the Vedic and post-Vedic eras, it is generally believed that a dedicated branch for healthcare was gradually established approximately between 400 BCE and 200 CE. Probably because the…
