course at a public researchinstitution in Illinois.This research study aimed to answer the following questions:a) Did the use of CITS or CTT predict students’ problem-solving self-efficacy or anxiety?b) Among students who used CITS or CTT, was problem-solving self-efficacy or anxiety related to students’ exam scores? Study Procedures One section of students (n = 37) enrolled in an advanced Circuit Analysis (Network Theory)course were randomly assigned to one of the two treatment groups (CITS or CTT). Over the courseof a semester, students were encouraged to engage with the MLE tutors when studying and in theirspare time. Three course examinations and three surveys were administered to intervention

Describe what programming is to you. (a) What does it mean to “be a programmer”? (b) Do you consider yourself a programmer? Why or why not? 3. Describe how programming is integrated into the curriculum in your major. (a) What did you learn from the curricular activities vs. on your own? 4. Tell me about the project you will be working on today. (a) Why did you choose to start it? (b) How long have you been working on it? (c) How often do you work on it? (d) When do you think it will be complete?Outtake 1. Think back
for PathDist happens either when PathDist does not reduce(character got stuck on its path to the goal) or when PathDist drops steeply (character took ashortcut and misses some gems).The observable behavior of abstraction is defined as adding a command and changingparameters at once, or as neglecting distractors or details (see Table 2 below). Examining thevisualizations, we originally expected that (a) some students would add all commands and thenchange their parameters at once and that (b) other students would change the parameter aftereach added command. However, it could be seen that the second behavior (b) was prevalent, andthat the first behavior (a) would only occur if there was a misconception present. Figure 4 showsan example of the
without any previous programming experience also had difficulties programmingwhile loops, as well as in understanding how MATLAB interprets an expression like A(b)when A is a MATLAB function or a matrix, and b is a variable or an index. Most of thosestudents had also difficulties interpreting the error messages and debugging their code.Audience Analysis: Students Interest and DemographicsFor the first offering, the Fall 04 tutorials, the number of students in attendance had a peak at 45and decreased as the semester progressed. Not surprisingly, there was a clear peak inattendance at the tutorial and office hours when homework involving MATLAB was due in oneof their 'for credit' courses, such as Control Theory or Thermodynamics. For example
with again amplifier is problematic as such a small resistance has significant noise current whichdegrades the receiver. Johnson–Nyquist noise13, also known as thermal noise is the electronicnoise generated by thermal agitation of charge carriers inside a conductor. Thermal noise isapproximately white meaning that the power spectral density is equal throughout the frequencyspectrum. The RMS value of the noise current in (8) is I n where k B is Boltzmann’s constant inJoules per Kelvin, T is the resistor’s absolute temperature in Kelvins, ∆ f is the noise bandwidth,and R is the resistance. To achieve the 70MHz bandwidth described above calls for a resistanceof 568 Ohms. The resistor has a thermal noise current of approximately 45.2nA

understanding of the inner workings of equipment can be seenin [22], [23]. VR labs, as used here, require the use of specialized hardware. The examples shown herehave been developed for the HTC Vive, but can also be used with the Oculus Rift or other VRhardware. The HTC Vive and Oculus Rift are two competing commercial VR systems that werereleased in March and April of 2016 respectively. The Oculus Rift consists of a head-mounteddisplay, shown in Figure 1a, with screens having 1080x1200 resolution per eye and incorporatesheadphones, gyroscopes, accelerometers, and a USB based stationary infrared sensor that tracksIR LEDs attached to the head mounted display [24], [25].Figure 1. a - Oculus Rift Head mounted display, b - Oculus touch controller, c

One can categorize the various approaches of classroompresentation as: a) Blackboard, b) Transparency, c) Whiteboard, d) Digitized Whiteboard, and e)Tablet PC.Lord and Perry [5] summarized various options that instructors typically use in a classroomsetting along with their advantages and disadvantages. Traditional method of writing on theblackboard is still favored by many instructors since it is easy to keep pace with students’learning, as well as to ‘walk’ the students through the complex mathematical derivation that istypical in many engineering courses. The final paradigm in classroom presentation is the use ofTablet PC, which provides the
connectivity amongCS majors and increasing the visibility of computer science across campus. In practice,attendance at LAN parties was modest and highly selective. Only those who (a) had a gamingPC and (b) were willing to transport their setup across campus became involved. This left uswith a small population of the most dedicated gamers where (a) most were male, with (b) analmost exclusive focus on “first-person shooter” games, and (c) a strong focus on highly-competitive “last man standing” tournaments. The consequence of this dynamic was that, whileeveryone on campus was invited in theory, in practice, a small hard-core group of malesparticipated; the appeal and “entry threshold” was simply too restrictive. Not only did the LANparty concept fail to

GbCC is an agent-based modeling program, powered byNetLogo Web [12], which extends the capabilities of traditional ABM and enables learners towork independently or collaboratively to participate in, modify (or author), and share models[13]. GbCC models lend themselves easily to achieving all of the higher-order uses of modelswhile also encouraging collaboration of many learners: (a) users can use the simulationindependently by changing slider values; (b) make changes to how models work using theNetLogo programming language; and (c) share their changes or data generated from the

Thegoal for both the seminar and TFLC were simple: provide faculty with technical andpedagogical information, and then offer support for their attempts to incorporate Tablet PCs intothe classroom teaching.A major innovation developed for the seminar, and used in the workshop, was a multipleprojector approach to help faculty see each of the following: (a) the instructor’s Tablet PCscreen with controls, (b) the classroom projected content, and (c) a sample student Tablet PCscreen. As part of the TFLC, faculty participants were required to develop material for one oftheir courses using a Tablet PC and then

Students who create an online portfolio or blog should make use of Google Analytics to track data about website traffic. With this tool, they can: a) see the number of site visitors and their geographic distribution; b) track the effectiveness of social media cross-links to bring visitors to the site; and c) identify keywords that bring visitors to the site.

In addition to in-class activities, this classrequires several assignments and group projects outside of class; each student is required tosubscribe to TopHat for attendance, lecture questions, discussion, and to help instructorsassess and measure student learning and understanding. A variety of participants were involved (n=80), comprised of 15 female students and65 male students. Of the total sample, 56% are classified as computer science majors and44% non-computer science majors. Approximately half of the class was sophomores(51.2%), while 22.5% were seniors, 17.5% were juniors, and 8.8% were freshmen.
