Coker, Jeffrey Scott – Journal of College Science Teaching, 2017
Despite numerous calls for science education to be driven by authentic investigation, many laboratory experiences continue to consist of disconnected weekly units during which students carry out instructions that lead to some predetermined finding. This study developed and evaluated a pedagogical design for introductory biology labs where students…

Boltax, Ariana L.; Kosinski-Collins, Melissa S.; Pontrello, Jason K. – Journal of College Science Teaching, 2016
This article describes the development of a model for an optional, research-based course that bridges two existing, traditionally separate, introductory science courses. This research course provided freedom for students to design and implement new experiments on the basis of technical foundations built from enrollment in separate introductory…

Coleman, Jill S. M.; Mitchell, Melissa – Journal of College Science Teaching, 2014
This article describes the implementation of high-altitude balloon (HAB) research into a variety of undergraduate atmospheric science classes as a means of increasing active student engagement in real-world, problem-solving events. Because high-altitude balloons are capable of reaching heights of 80,000-100,000 ft (24-30 km), they provide a…

Bonney, Kevin M. – Journal of College Science Teaching, 2014
This article describes an interrupted case study that intersperses information about diffusion and osmosis with content review and knowledge application questions, as well as a simple experiment that can be conducted without the use of a laboratory. The case study was developed for use in an introductory undergraduate biology course. The case…

Yang, Li-Hsuan – Journal of College Science Teaching, 2012
This article describes engaging students in two simple observations to address the concepts of changes of states, heat, temperature, and molecular potential and kinetic energy. It also discusses how these concepts can enable students to further explore and understand interesting and significant phenomena and research in multiple areas of science.…

Robertson, Katherine – Journal of College Science Teaching, 2012
For success after graduation, science undergraduates must master a number of skills such as scientific literacy (interpretation and evaluation of primary research articles) and effective communication. Many researchers have recognized the benefits of journal clubs in developing such skills, and a large body of literature describes how they may be…

Ghaffari, Shahrokh – Journal of College Science Teaching, 2011
Demonstrations are used in chemistry lectures to improve conceptual understanding by direct observation. The visual aid described here is designed to demonstrate the change in state of matter with the change of temperature and the change of pressure with temperature. Temperature is presented by the rate of airflow and pressure is presented by…

Avard, Margaret Marie – Journal of College Science Teaching, 2010
Preservice elementary education students often do not have a good feel for the process of science. Many may be acquainted with the steps of the scientific method but have never been through the scientific process. An exercise was designed using temperature-logging iButtons (Thermochrons) to improve knowledge of and familiarity with the process of…

Rettig, Jessica E.; Smith, Geoffrey R. – Journal of College Science Teaching, 2009
Research-like experiences range from relatively "canned" labs that are highly controlled by the instructor (such as those described in Lord and Orkwiszewski 2006) to more individually designed projects (e.g., Switzer and Shriner 2000; Wyatt 2005). This article describes a laboratory approach that allows for many of the benefits of independent or…

Ruebush, Laura; Sulikowski, Michelle; North, Simon – Journal of College Science Teaching, 2009
Scientific modeling is an integral part of contemporary science, yet many students have little understanding of how models are developed, validated, and used to predict and explain phenomena. A simple modeling exercise led to significant gains in understanding key attributes of scientific modeling while revealing some stubborn misconceptions.…

Wise, Kevin; Bluhm, William J. – Journal of College Science Teaching, 2008
This article describes a twist on the basic "Science 101" investigation of having students observe a birthday candle before, during, and after burning. It engages students in exploring the attributes of a candle, introduces them to the concepts of empirical observation and investigation, and involves them in developing and conducting a burning…

Porta, Angela R.; Dhawan, Puneet – Journal of College Science Teaching, 2006
Undergraduate biology programs are currently undergoing reform to involve students in biomedical research. Engaging students in more active, hands-on experiments allows students to discover scientific principles for themselves, and to develop techniques of critical thinking and problem solving. This models the world of real scientific research,…

Polacek, Kelly Myer; Keeling, Elena Levine – Journal of College Science Teaching, 2005
To teach students to think like scientists, the authors modified their laboratory course to include regular opportunities for student practice of inquiry and the scientific process. Their techniques are simple; they can be implemented without rewriting lab manuals, require little additional grading beyond typical lab reports, and are applicable…

Dinan, Frank J. – Journal of College Science Teaching, 2005
Case-based laboratories offer students the chance to approximate real science. Based on interesting stories that pose problems requiring experimental solutions, they avoid the cookbook approach characteristic of traditional undergraduate laboratory instruction. Instead, case-based laboratories challenge students to develop, as much as possible,…

Kendler, Barry S.; Grove, Patricia A. – Journal of College Science Teaching, 2005
A serendipitous finding involving static magnetic fields can be used to design experiments suitable for both science and nonscience majors. It has been reported that organisms respond differently to high-gauss magnetic fields generated by north poles than they do to those generated by south poles. Experimental tests of this hypothesis are ideal…
