Walkup, John R.; Key, Roger A.; Talbot, Patrick R. M. – Physics Education, 2019
A lab activity for teaching physics students the fundamentals of statistical analysis during the first few weeks of instruction is described. This activity involves students timing a pulse of light generated by an Arduino device of fixed duration with individual timers (e.g. stopwatch, iPhone timer). To select the most precise timing methods and…

Dopico, Eduardo; Linde, Ana R.; Garcia-Vazquez, Eva – Journal of Biological Education, 2014
Introducing research in undergraduate biology studies may contribute to creating research vocations and generate the idea that science may influence all aspects of common life. However, laboratory practices are too often disconnected from current investigations and rarely address real-life questions that are really interesting for students.…

Holmes, N. G.; Bonn, D. A. – Physics Teacher, 2015
In a recent report, the American Association of Physics Teachers has developed an updated set of recommendations for curriculum of undergraduate physics labs. This document focuses on six major themes: constructing knowledge, modeling, designing experiments, developing technical and practical laboratory skills, analyzing and visualizing data, and…

Walker, J. P.; Sampson, V.; Southerland, S.; Enderle, P. J. – Chemistry Education Research and Practice, 2016
This study examines the extent to which the type of instruction used during a general chemistry laboratory course affects students' ability to use core ideas to engage in science practices. We use Ford's (2008) description of the nature of scientific practices to categorize what students do in the laboratory as either empirical or…

Grammer, Robert T. – American Biology Teacher, 2012
We propose a procedure for the assay of fermentation in yeast in microcentrifuge tubes that is simple and rapid, permitting assay replicates, descriptive statistics, and the preparation of line graphs that indicate reproducibility. Using regression and simple derivatives to determine initial velocities, we suggest methods to compare the effects of…

Basey, John; Sacket, Loren; Robinson, Natalie – International Journal for the Scholarship of Teaching and Learning, 2008
Variations in science lab design can differentially impact student learning. Quantification of these differential impacts can be used in modeling--an approach we term "optimal lab design." In this study we estimated relative influences of six characteristics of lab design on students' attitudes toward science labs in three different…

Hawk, James A.; And Others – American Biology Teacher, 1980
A three-point linkage system in tomatoes is used to explain concepts of gene mapping, linking and statistical analysis. The system is designed for teaching the effective use of statistics, and the power of genetic analysis from statistical analysis of phenotypic ratios. (Author/SA)

Fenk, Christopher J.; Kaufman, Nathan; Gerbig, Donald G., Jr. – Journal of Chemical Education, 2007
A new, fast and effective colorimetric analysis of the artificial sweetener aspartame is presented for application in undergraduate laboratory courses. This new method incorporates the use of a modified biuret reagent for selective detection and analysis of aspartame in aqueous solutions. The modified reagent is less caustic than the traditional…

Spencer, R. Donald – Journal of Chemical Education, 1984
Describes an experiment (using plastic bags) designed to give students practical understanding on using statistics to evaluate data and how statistical treatment of experimental results can enhance their value in solving scientific problems. Students also gain insight into the orientation and structure of polymers by examining the plastic bags.…

Hursch, Thomas Mercer – American Biology Teacher, 1979
Two statistical tools, the Chi-square and standard error approaches, are compared for use in Mendelian genetics experiments. Although the Chi-square technique is more often used, the standard error approach is to be preferred for both research investigations and student experiments. (BB)

Krieger, Michael E.; Stith, James H. – Physics Teacher, 1990
The use of computer spreadsheet programs in the physics laboratory is discussed. An example of this application with a conservation of energy laboratory is presented including the cases of a rolling sphere and a sliding sphere. (CW)

Hanke, Craig J.; Bauer-Dantoin, Angela C. – Advances in Physiology Education, 2006
Classroom discussion of scientific articles can be an effective means of teaching scientific principles and methodology to both undergraduate and graduate science students. The availability of classic papers from the American Physiological Society Legacy Project has made it possible to access articles dating back to the early portions of the 20th…

Hudgins, R. R.; Reilly, P. M. – Chemical Engineering Education, 1989
Discussed are problems encountered when a gas absorption experiment with strong measurement error is used. Notes students either avoid the experiment or report it as defective. Provides ideas to make lab experiments more instructive. (MVL)
