The concepts of randomness and variation are pervasive in science. The purpose of this study was to document how post-secondary life science students explain randomness and variation, infer relationships between their explanations, and ability to describe and identify appropriate and inappropriate variation, and determine if students can identify…

Many active learning pedagogies depend on students' preparing for class in advance. One common method for holding students accountable for this preparation is the use of reading quizzes. When used thoughtfully, reading quizzes can also actually promote student learning through the testing effect. In this article we describe why and how we use…

Background: This investigation was designed to uncover the relations between students' cognitive and metacognitive strategies used during a complex climate simulation. While cognitive strategy use during science inquiry has been studied, the factors related to this strategy use, such as concurrent metacognition, prior knowledge, and prior…

This curriculum inquiry explores scholarly influence by examining how Joseph J. Schwab's ideas travelled over time and how his research was disseminated. The study begins with Schwab's biography and a literature review, followed by descriptions of the research method and sources of evidence. Data analysis centre on (1) The influence of Schwab's…

This research is conducted to find out whether the attitudes of preservice classroom teachers towards mother tongue, life science, mathematics and science teachings predict their attitudes towards teaching profession or not. Research is conducted in pursuant of relational screening model, which a nonempirical design is belonging to the…

Every year millions of people contract cancer in the world, and according to prediction of the World Health Organization by the year 2030 there will be about 27 million new cases. Because of these figures and the resulting social and economic implications of this disease, radiotherapy, which is one form of treatment that uses ionizing radiation,…

This essay describes Rasch analysis psychometric techniques and how such techniques can be used by life sciences education researchers to guide the development and use of surveys and tests. Specifically, Rasch techniques can be used to document and evaluate the measurement functioning of such instruments. Rasch techniques also allow researchers to…

When undergraduate biology students learn to explain biological mechanisms, they face many challenges and may overestimate their understanding of living systems. Previously, we developed the MACH model of four components used by expert biologists to explain mechanisms: Methods, Analogies, Context, and How. This study explores the implementation of…

The dramatic decline in youth interest in science, technology, engineering and mathematics (STEM) during adolescence, both in the USA and internationally, has been a phenomenon of societal concern for several decades. The Synergies project was launched to help deal with this issue. In this paper, we report findings from the first two years of our…

Boundary crossing competence is needed to tackle complex problems and should therefore be facilitated in education. The Regional Learning Environment, a typical service learning environment practiced in Dutch life sciences education, offers students ample opportunities to develop boundary crossing competence through multi-stakeholder…

The aim of this study is to identify cell-related misconceptions among fifth graders attending middle schools in Turkey and examine the impact of microscopy on the elimination of these misconceptions. The study was conducted with the participation of 87 fifth grade students (schoolchildren are nearly 11 years old) attending a middle school in Agri…

In this thesis, I study some aspects of how students learn to use math to make sense of physical phenomena. Solving physics problems usually requires dealing with algebraic expressions. That can take the form of reading equations you're given, manipulating them, or creating them. It's possible to use equations simply according to formal rules of…

Technological and methodological advances, in particular next-generation sequencing and chromatin profiling, has led to a deluge of data on epigenetic mechanisms and processes. Epigenetic regulation in the brain is no exception. In this commentary, Ehud Lamm writes that extending existing frameworks for thinking about psychological development to…

This article describes the kindergarten unit on environmental awareness, "Who Wants to Live and Grow in a Garbage Dump?," which integrated life science, health and nutrition concepts, and relationships around the topic of "soil." Science Technology Education and Mathematics (STEM) activities used in the lesson plans were…

Each January from 2010 to 2014, an undergraduate workshop on modeling biological systems was held at Lehman College of the City University of New York. The workshops were funded by a National Science Foundation (NSF) Expedition in Computing, "Computational Modeling and Analysis of Complex Systems (CMACS)." The primary goal was to…
