Shakur, Asif; Connor, Rainor – Physics Teacher, 2018
With the introduction of the Wireless Smart Cart by PASCO scientific in April 2016, we expect a paradigm shift in undergraduate physics laboratory instruction. We have evaluated the feasibility of using the smart cart by carrying out experiments that are usually performed using traditional PASCO equipment. The simplicity, convenience, and…

Broder, Darren; Burleigh, James; Christian, Matthew; Mowry, Shawn; Hassel, George E. – Physics Teacher, 2017
The Exploding Carts is a popular introductory physics activity in which a one-dimensional explosion is simulated utilizing two dynamics carts that are pushed apart by a spring-loaded plunger released from one of the carts. Traditional treatments of the Exploding Carts usually involve multiple trials where the mass of one or both of the carts is…

Lamore, Brian – Physics Teacher, 2016
For years the fan cart has provided physics students with an excellent resource for exploring fundamental mechanics concepts such as acceleration, Newton's laws, impulse, momentum, work-energy, and energy conversions. "The Physics Teacher" has even seen some excellent do-it-yourself (DIY) fan carts and activities. If you are interested…

Chen, Su-Yen; Fang, Sheng-Ping – Journal of Research in Reading, 2015
This study set out to develop a Chinese Author Recognition Test (CART) that might be used as a measure of objective print exposure for college students in Taiwan. We found that there is a linkage between print exposure and general reading achievement for college students. We also found that, among self-reported reading habits, comparative reading…

Messerle, Louis – Journal of Chemical Education, 2018
iSchlenk, a portable instructional cart with equipment for hands-on student experience in safe handling of air-sensitive, moisture-sensitive, toxic, pyrophoric, and/or radioactive chemical materials, is described. The cart, for use by =4 students, has compressed air and vacuum from a diaphragm vacuum pump supplied to 4 three-port Schlenk lines…

Corridoni, Tommaso; D'Anna, Michele; Fuchs, Hans – Physics Teacher, 2014
The damped oscillator is discussed in every high school textbook or introductory physics course, and a large number of papers are devoted to it in physics didactics journals. Papers typically focus on kinematic and dynamic aspects and less often on energy. Among the latter, some are devoted to the peculiar decreasing behavior of energy…

Lung, Heidi K. – ProQuest LLC, 2013
This study investigated the practice of elementary art teachers who utilize carts for the delivery of art lessons; to understand how the art on a cart practice influences art educators' approaches to curriculum development and instruction; and to identify challenges, benefits, and best practices. The practice of art on a cart is defined as the…

Cohen, Ira L.; Liu, Xudong; Hudson, Melissa; Gillis, Jennifer; Cavalari, Rachel N. S.; Romanczyk, Raymond G.; Karmel, Bernard Z.; Gardner, Judith M. – Canadian Journal of School Psychology, 2017
The PDD Behavior Inventory (PDDBI) has recently been shown, in a large multisite study, to discriminate well between autism spectrum disorder (ASD) and other groups when its scores were examined using a machine learning tool, Classification and Regression Trees (CART). Discrimination was good for toddlers, preschoolers, and school-age children;…

The study, "A Model for Success: CART's Linked Learning Program Increases College Enrollment" examined whether students who enrolled in courses at a high school that combined academics and technical education had higher college enrollment rates than students who did not. The research described in this report does not meet What Works…

Paoletti, Teo; Moore, Kevin C. – For the Learning of Mathematics, 2018
Supporting students developing understandings of function has been a notoriously elusive task in mathematics education. We present Thompson and Carlson's (2017) description of a covariational meaning of function and provide an example of a student who maintains meanings compatible with this description. We use this student's activity to illustrate…

Cohen, Ira L.; Liu, Xudong; Hudson, Melissa; Gillis, Jennifer; Cavalari, Rachel N. S.; Romanczyk, Raymond G.; Karmel, Bernard Z.; Gardner, Judith M. – Journal of Autism and Developmental Disorders, 2016
In order to improve discrimination accuracy between Autism Spectrum Disorder (ASD) and similar neurodevelopmental disorders, a data mining procedure, Classification and Regression Trees (CART), was used on a large multi-site sample of PDD Behavior Inventory (PDDBI) forms on children with and without ASD. Discrimination accuracy exceeded 80%,…

Aurora, Tarlok S.; Brunner, Bernard J. – Physics Education, 2011
In introductory physics, students learn that an object tossed upward has a constant downward acceleration while going up, at the highest point and while falling down. To demonstrate this concept, a self-propelled fan cart system is used on a frictionless track. A quick push is given to the fan cart and it is allowed to move away on a track under…

Mungan, Carl E. – Physics Education, 2012
A pair of objects on an inclined plane are connected together by a string. The upper object is then connected to a fixed post via a spring. The situation is first analysed as a classroom exercise in using free-body diagrams to solve Newton's second law for a system of objects upon which many different kinds of force are acting (string tension,…

Koon, Sharon; Petscher, Yaacov – Regional Educational Laboratory Southeast, 2015
The purpose of this report was to explicate the use of logistic regression and classification and regression tree (CART) analysis in the development of early warning systems. It was motivated by state education leaders' interest in maintaining high classification accuracy while simultaneously improving practitioner understanding of the rules by…

Mungan, Carl E. – Physics Education, 2012
A simple model is developed that predicts the coefficient of rolling friction for an undriven laboratory cart on a track that is approximately independent of the mass loaded onto the cart and of the angle of inclination of the track. The model includes both deformation of the wheels/track and frictional torque at the axles/bearings. The concept of…
