A signature of life is that biological molecules occur as a single stereoisomer with respect to each chiral center, and this is echoed in the structures of biological polymers. Thus, circular dichroism (CD) has emerged as a hallmark of biomolecular structures. The tangible and familiar phenomenon of raw egg white's conversion from transparent…

Over the past decade, mechanistic cross-linking probes have been used to study protein-protein interactions in natural product biosynthetic pathways. This approach is highly interdisciplinary, combining elements of protein biochemistry, organic chemistry, and computational docking. Herein, we described the development of an experiment to engage…

Introductory science courses serve a population of students in the major (i.e., chemistry) as well as those students outside the discipline (i.e., premed, biology, engineering). In an effort to help this diverse population of students connect personally with the content of the course, we sought ways to include student-centered activities, provide…

Producing a deep bass tone by striking a large 3 m (10 ft) flexible corrugated drainage pipe immediately grabs student attention. The fundamental pitch of the corrugated tube is found to be a semitone lower than a non-corrugated smooth pipe of the same length. A video (https://youtu.be/FU7a9d7N60Y) of the demonstration is included, which…

For this article, we use a 3D printer to print a surface similar to universal gravitation for demonstrating and investigating Kepler's laws of planetary motion describing the motion of a small ball on the surface. This novel experimental method allows Kepler's laws of planetary motion to be visualized and will contribute to improving the…

A commercial hollow fiber blood oxygenation laboratory experiment was used to introduce lower level engineering students to mass balances in a two-phase system. Using measured values of concentration and flow rate, students calculated the rate of mass transfer from the gas phase and into the liquid phase, and compared the two values to determine…

Electromagnetic induction is an important, yet complex, physics topic that is a part of Croatian high school curriculum. Nine Croatian high school students of different abilities in physics were interviewed using six demonstration experiments from electromagnetism (three of them concerned the topic of electromagnetic induction). Students were…

The opportunity to engage in scientific research is an important, but often neglected, component of undergraduate training in biology. We describe the curriculum for an innovative, course-based undergraduate research experience (CURE) appropriate for a large, introductory cell and molecular biology laboratory class that leverages students' high…

In this study, it is aimed to determine effects of pre-service elementary school teachers' misconceptions about short circuit and open circuit on their ability to set up simple electric circuits. The sample of the research is composed of 41 teacher candidates studying at Dokuz Eylul University. Open-ended questions and semi-structured interview…

Discrepant events, contrary to previous to be true, are events which has unexpected results used to compare students together with their beliefs and to attract their attention They are used for the purpose of attracting students' attention, encouraging them to think about a topic, stimulating them to work out a contradictory case by changing usual…

The climate, being a complex system, is difficult for people to understand. If better education is to be designed to improve the public's understanding of the subject, educators must be aware of the prior knowledge that students bring with them to the classroom since it is through that prism that people make sense of the world. As such, the aim of…

The National Research Council (2012) recently published A Framework for K-12 Science Education that describes a vision for science classrooms where students engage in three dimensions--scientific and engineering practices, crosscutting concepts, and disciplinary core ideas--to explain phenomena or observations they can make about the universe…

The intent of this research is to evaluate the use of a formative assessment probe about balance and torque. The lesson was conducted with 52, 11th grade students studying in two physics classes at a state high school. A formative assessment probe was used at both the beginning and end of the study. After the students' prior knowledge about…

Inquiry-based learning is a usable approach in developing gifted and talented students' learning and one that overlaps with their properties and learning needs. The aim of this research was to examine the effect of guided inquiry-based learning approach compared with that of traditional teacher-centered instruction on gifted and talented eighth…

This case study reports my experiences of a PhD project applying the microgenetic approach to study changes in students' conceptual structures as they developed understanding of topics in physics. The microgenetic approach involves sampling (referring to the frequency of application of data collection probes) a phenomenon at a rate which is high…
