Stephen J Lind

Trane Acoustics Lab

La Crosse, Wisconsin

9:30 to 10:15 AM

 

Brief Bio:

Steve Lind received a Bachelor of Arts in Physics from the University of Northern Iowa.  Steve proceeded to get a Master of Science in Engineering degree with a major in Acoustics from the University of Texas at Austin. He currently works in the Experimental Mechanics and Acoustics group at Ingersoll Rand with a focus on Trane air conditioning products.  Steve has worked at the Trane Acoustics Lab in La Crosse, Wisconsin since 1998.  Prior to moving to Wisconsin, Steve was an acoustical consultant for 10 years.  He is a registered Professional Engineer in Oregon with a specialization in acoustics and is Board Certified by the Institute of Noise Control Engineering.  Steve is active in acoustic standards efforts at the Air Conditioning Heating and Refrigeration Institute (AHRI) and at the Acoustical Society of America.  Steve was co-chair of the ANSI/ASA working group 52 that revised and updated the classroom acoustics standard S12.60 in 2010.

 

Acoustics and the Classroom

In May 2010 a new standard for classroom acoustics (ANSI/ASA S12.60 Acoustical Performance Criteria, Design Requirements, and Guidelines for Schools, Part 1: Permanent, Site-Built Schools) was adopted by ANSI through the standards activities at the Acoustical Society of America (ASA).  The intent of the standard is to provide learning spaces where communication is not impeded by the acoustical environment in the room. Important room parameters considered are reverberation time, noise levels due to building equipment, and noise levels intruding from sources outside of the learning space.  Excessive background noise or reverberation in may interfere with speech communication and thus present an acoustical impediment to learning. All those in a classroom, including teachers and adult learners, will benefit from a classroom having the acoustical characteristics recommended in the standard. However, young children and persons with hearing, language, speech, attention deficit, or learning disabilities benefit even more.  The standard is being made available without cost to the user. A brief overview of pertinent issues regarding room acoustics, transmission loss, and equipment noise will be presented. The requirements of the standard along with methods to evaluate rooms for conformance will be discussed. 

 

Steven N Kanim

New Mexico State University

Las Cruces, New Mexico

11:45 to 12:30 PM

Brief Bio:

Steve Kanim is an associate professor in the Department of Physics at New Mexico State University.  His research interests are in the teaching and learning of physics.  He received his bachelor’s degree in electrical engineering from UCLA in 1981 and worked for a few years as an engineer in Silicon Valley.  The prospect of summers off led him to try teaching, and he received a secondary science teaching certification from San Jose State University in 1984.  He taught high school physics for six years, first in Palo Alto, California, and then in Las Cruces, New Mexico.  He received his Ph.D. in physics from the University of Washington in 1999, and has been at NMSU since 1998.  His current research interests are in student use of proportional reasoning in physics and in developing experiments to test models of cognition.

 

Proportional reasoning as a predictor of success in introductory physics

Instructors often describe differences in the level of preparation of introductory physics students at different institutions, and in different courses (for example, students in algebra-based versus calculus-based courses).   As a measure of student preparation, instructors and researchers have used pretests of mathematics and of scientific reasoning ability as predictors.  For example, Coletta has shown that students who score well on the Lawson Classroom Test of Scientific Reasoning ability have higher Hake gains than students who do not.  We have been looking at correlations between student performance on proportional reasoning pretest questions and scores on a conceptual final examination in a physics lab as part of our attempts to understand more about what constitutes adequate preparation for physics.  In this talk I will describe the pretest questions we have been using and our attempts to better understand what is being measured by these questions.  We have found that varying the context of these questions affects student performance even when the proportional reasoning content remains the same.  This effect is more pronounced for women than for men.  In addition, we have found strong sensitivities to wording for some of the questions we have asked.  I will also describe curricula in development that we hope will be useful in strengthening students' proportional reasoning skill.

1:30 to 3:30 PM

Workshop on NTIPERS: Research-Based Reasoning Tasks for Introductory Mechanics

A common question instructors wrestle with is: How do I get my students to develop a strong understanding of physics? In this workshop you will explore some new materials designed to get students to think about fundamental concepts in alternative and multiple ways to promote robust learning. Participants will work with a variety of tasks and task formats that require students to think about the basic physics in the domains of kinematics and dynamics, including rotational dynamics, in nonstandard ways. Participants will be given a CD with more than 400 tasks, and other materials.  (CD’s will be given to first 24 participants.)
