...Takako Hirokawa, Noah Finkelstein, and H. J. Lewandowski† Department of Physics, University of Colorado Boulder, Boulder, CO 80309 (Dated: March 4, 2014) In response to national calls to better align physics laboratory courses with the way physicists engage in research, we have developed an epistemology and expectations survey to assess how students perceive the nature of physics experiments in the contexts of laboratory courses and the professional research laboratory. The Colorado Learning Attitudes about Science Survey for Experimental Physics (E-CLASS) evaluates students’ shifts in epistemology and affect at the beginning and end of a semester. Also, at the end of the semester, the E-CLASS assesses students’ reflections on their course’s expectations for earning a good grade. By basing survey statements on widely embraced learning goals and common critiques of teaching labs, the E-CLASS serves as an assessment tool for lab courses across the undergraduate curriculum and as a tool for PER research. We present the development, evidence of validation, and initial formative assessment results from a sample that includes 45 classes at 20 institutions. We also discuss feedback from instructors and reflect on the challenges of large-scale online administration and distribution of results. I. INTRODUCTION Laboratory courses offer significant opportunities for engagement in the practices and core ideas of science. Laboratory course environments typically have apparatus, flexible...

...Thong Nguyen General Physics II Laboratory Lab Report Introduction/Purpose: The purpose of this lab was to find the measurement of the length of how long it takes for a sound to flow in a 1 meter-long tube within 5% error. The technique is to record the time of the echo sound made by snapping fingers. A microphone attached to the computer would be placed at the tube’s opening to determine the speed of sound at room temperature. Once the fingers were snapped at the opening, they created the sound, which traveled to the end of the tube back and forth. In addition, the microphone would collect the sound and transfer that information into the computer. After bouncing off from the closed end, the sound would hit the microphone; the computer would displace a graph, which shows the initial sound and the echo. The speed of sound would be determined by using the round-trip time and the length of the tube. Materials & Procedures: The materials that were used in this experiment were: * Computer * Vernier computer interface * Logger Pro * Vernier Microphone * finger * 1 meter-long PVC tube closed at one end * Thermometer * meter stick The experiment started with measuring the room temperature. The Vernier Microphone was attached to Channel 1 of the interface. The graph of sound level vs. time was observed in the file “33 Speed of Sound” in the Physics with Vernier folder.. The microphone was placed at the tube’s opening to detect both the...

...The Modern Development of Atomic Theory According to Democritus, “Nothing exists except atoms and empty space; everything else is opinion.” This conveys the controversy in scientific investigations made in defining a singular molecule. Since 460 BC, atomism has been an alternating concept of chemistry. Several significant scientists have contributed to this field profoundly. The modern development of the atomic theory is based on researches and discoveries of Democritus, John Dalton, J.J. Thomson, Robert Andrews Milikan, Ernest Rutherford, James Chadwick, and Niels Bohr. Robinson, Bertsch, both Professors of Physics, and McGrayne, a science writer, wrote for Encyclopedia Britannica defining an atom as the “smallest unit into which matter can...

...Phvsics Lab Report Format (Sample Report Attached) General Remarks: Writing a lab report is the only way your TA will know what you have done during the lab and how well you have understood the process and the results. Part of your lab experience should be learning how to organize and present your work in a scientific way. There is no framework that can be used as a "one size fits all", therefore this sample lab report should only be used as an example. Any lab report should have the following features: o It should be concise but should also contain the necessary details and well-developed explanations. It should be organized. You should enable the reader to quickly find the information he or she may be interested in. It should contain all the relevant information and reasoning. You should enable the reader to validate your conclusion. A possible way to achieve this is using the following framework: o o . o o o o . Obiective: State what you want to achieve in this experiment A formal way to do this is to state a question or hypothesis that you want to address. Method: You should include a summary of the lab procedure in your words; do not merely copy what is in the manual. This section should demonstrate your understanding of what exactly you measured and how you measured it. Data: In this section you should include the raw data you measured; generally, an estimate of the error should accompany all measured values. Be sure to present...

Takoda Bingham Salem Alajmi Porter Lewis Particle equilibrium Objective: To examine the condition for static equilibrium of a particle. Theory: If the net force on a body is zero then it will not accelerate. If it’s at rest it has static equilibrium. If an unbalanced force acts on a body it will be accelerated. When unbalanced the particle can achieve its equilibrium by having a force that is applied that has an equal magnitude and is in the opposite direction. Procedure: 1. Attach 100 g (1.0 N) at 0 degrees and 100 g (1.0 N) at 270 degrees on the force table. Zero force probe and pull the third string until the ring is center and read angle and force. Repeat 2 more times. 2. Move the 270 degree weight to 240 degrees and measure the angle and force. Repeat 2 more times. Then add 1 N to the mass holder at 240 degrees and repeat the measurements. 3.

...Computational Estimation of Aerodynamic Characteristics of Airships ME 399 PROJECT COURSE REPORT August-November 2013 1 November 2014 Abstract The Aerodynamics of ZHIYUAN-1 Airship with fin and Gondola has been studied using Reynolds Averaged Navier-Stokes equations. The various aerodynamic characteristics of airship have been successfully studied using overset grids and the computed flight parameters are then compared with the experimental data and are found to be agreeing well for small angle of attacks. The static stability of the airship has also been investigated and the aerodynamic center of the airship has been located as a part of the stability analysis. 1 Introduction Recent renewed interest in airships with varied applications in the field of advertisement, cargo transport, surveillance, communication systems, extending Internet access in remote areas is the primary motivation for this study. The estimation of aerodynamic characteristics is important for the design of control and propulsion systems of the airship. Airship analysis has traditionally been done using inviscid potential flow methods coupled with boundary layer corrections based on integral momentum methods have been used to estimate the drag coefficient of airships [1-4]. However, the application of these methods is strictly restricted to non-separating flows and flows at zero or small angles of attack. In real-life applications, the airship does encounter flow separation at large...

...THE EFFECTS OF PERSONALITY TYPE ON ENGINEERING STUDENT PERFORMANCE AND ATTITUDES* R.M. Felder Department of Chemical Engineering North Carolina State University G.N. Felder Department of Physics Stanford University E.J. Dietz Department of Statistics North Carolina State University Abstract The Myers-Briggs Type Indicator® (MBTI) was administered to a group of 116 students taking the introductory chemical engineering course at North Carolina State University. That course and four subsequent chemical engineering courses were taught in a manner that emphasized active and cooperative learning and inductive presentation of course material. Type differences in various academic performance measures and attitudes were noted as the students progressed through the curriculum. The observations were generally consistent with the predictions of type theory, and the experimental instructional approach appeared to improve the performance of MBTI types (extraverts, sensors, and feelers) found in previous studies to be disadvantaged in the engineering curriculum. The conclusion is that the MBTI is a useful tool for helping engineering instructors and advisors to understand their students and to design instruction that can benefit students of all types. I. INTRODUCTION People have different learning styles that are reflected in different academic strengths, weaknesses, skills, and interests. Given the almost unlimited variety of job descriptions within engineering, it is safe to say that students...
