effectiveness in regards to the project’s purpose and information’s credibility. One of the librarians presented an option to use for evaluating information sources. The ABCD process was adapted from a pneumonic that was used at Harvard University Libraries. The “A” represents Authority---who provided the information and what is the affiliation of the person. “B” represents bias. Is it obvious that the creator has a specific point of view or is there an effort to represent the entire picture? Bias is not necessarily bad, but must be recognized and used properly in the project. “C” stands for how current the item is. If recent information is required on a topic, something from 1975 probably will not be adequate. Students were

, mechanical, aerospace, andchemical engineering involve the study of interconnected dynamic systems modeled bydifferential or difference equations, such as feedback control systems. The traditional frameworkfor the analysis and design of such systems is based on the transfer function, which modelssingle-input single-output (SISO) linear time-invariant (LTI) systems. It can be defined by takingthe Laplace transform of a differential equation (in continuous time) or the z-transform of adifference equation (in discrete time).In the continuous LTI case, the differential equation may be written the form ua(D) = yb(D),where u ∈ C∞ is the input signal, y ∈ C∞ is the output signal, a, b ∈ R[x] are real polynomials withb = 0, and D is the differential

Using incremental BCRanalysis, determine the best alternative to be recommended.Solution (Note: All cash flows presented from now on are to be understood as to be multipliedby 1000. So for example, in table 1, the cost of alternative A is to be understood as $4 million($4,000 *1000), the PW Benefit of alternative H as $20 million (20,000 *1000), and so forth.):Step 1) Since the potential alternatives are already provided, step 1 is already taken care of. Step2) we calculate the BCR of each alternative, which is shown in Table 2; only those alternativeswith BCR ≥ 1 are further
this paper,we argue that there can be a trade-off between emphasizing mathematical sense-making andemphasizing traditional problem-solving, both of which we define more carefully below.Our data come from the first-semester physics course taken by almost all engineering majors atBig University. One section, taught by an experienced, well-regarded professor, emphasized“traditional” quantitative problem solving (Instructor A). Two other sections, one taught by anovice instructor (Instructor B) and the other taught by an instructor experienced with “active-learning” pedagogy (Instructor C), emphasized mathematical sense-making. Our evidence showsthat traditional problem solving and mathematical sense-making do not automatically reinforceeach other

The average GPA at the beginning of course
coursecame from their participation in a team project that called for designing a sustainablemanufacturing process for a product. The teams were encouraged to select the product central totheir design, instead of the product being chosen for them by the instructor. Twenty-six engineering students in Class B, a course in integrated product development,participated in this study. A majority of the students in this class reported that they were pursuinga master’s degree in engineering, although four undergraduates and two doctoral alsoparticipated in the study. The age of the students in Class B ranged from 22 to 45 year old withmajority of the students reporting an age of less than 27 years old. The aim of this class is tofamiliarize students
alsosignificant (p = 0.0001, t = 7.21). The conclusion from Figure 2 is that the students must worktogether and be engaged in order to achieve the high tRAT scores.When the students do the tRAT, they do not know the correct answers until they scratch the IF-AT card. If everyone in the team has a different answer, they do not know who is correct andmust debate to determine the correct answer. During the tRAT, typical conversations overheardby the instructors include students saying “Why did you choose A?”, “I chose A because of X,which means that Y must be true” and “I remember reading X, Y, Z, so the answer cannot be B”.

When a person seesobjects in 3D space, the two eyes converge to focus on an object of interest (e.g., the chair inFigure 2-a) and another object (e.g., the cube) appears shifted differently in the retina of left eye(Figure 2-b) versus right eye (Figure 2-c) due to binocular disparity. Even if the two eyesreceive the different images respectively, our brain not only

the survey were used as the sample assessed in this paper. In order toensure this group was representative, the distribution of final course grades were compared forthe survey respondents to 1) all students who completed the course in one of the sections wherethe survey was distributed and 2) all students taking the class. The survey respondent group hada slightly higher response rate from students earning A or B grades and a slightly lower responserate from students earning D or F grades. As illustrated in Table 2, the groups appear to havesimilar final grade distributions. No other factors were evaluated to determine differencesbetween groups.Table 2: Distribution of students in the sample Survey All
self-identify as visual learners, so a graph is more appropriate for theirlearning style.In reality, B-/C+ students do not suddenly earn 100% on all remaining assignments; nor do theytypically stop turning in work for the last two weeks of a course. Instead, they tend to continue atthe same level of performance.In my freshman Materials & Processes class, I staple each student's course grade graph to his orher graded Midterm Exam. The passing grade in this class is 70%. In the following course gradegraphs from Fall 2014, the vertical scale is 70% to 100%, unless the student has course gradesbelow 70% (Students Black and Red). Students can readily see whether they are improving overtime, and whether they are on track to pass the course

Thisled to a structurally strong chassis, as well as the added effect of a tighter turning radius for moreresponsive control. Although enough room was created for the inclusion of necessary sensors,like encoders, it was not as much room as the expanded form which allowed for other sensors,such as line tracking sensors and ultrasonic range finders.Students needed to decide, as a group, which design approach would be best for them to achievethe goals of their final project. Their final projects required them to complete a task throughdesigning and programming a robot. (a) (b

Twenty-three studentsagreed to participate in the survey and were present on the day of the study.MethodologyStudents received a background lecture in work-energy methods for computing deflections theweek before the study began, and were assigned relevant readings in their course textbook to becompleted before attending the study, similar to a flipped classroom. The study began with abrief presentation of the principle of virtual work for trusses after which students were dividedinto two groups, Group A and Group B. Group assignments were posted prior to studycommencement. Mid-term exam #1 grades were used to ensure equal ability levels were presentin each group. Informed consent, under approval of
significantly limited its widespread adoption but is still a well researched andstudied topic3. This method allows only discrete and limited types of responses (eg. A, B, C orD), so questions have to be restricted to multiple choice type of questions.The third method (ABCD voting cards) in which each student has 4 big voting cards (each withA, B, C and D printed on it) and votes for an answer, solves the bigger drawbacks of the clickermethod by simplifying the entire response process4. It ends up loosing anonymity (if studentslook at others’ cards) and is also restricted to multiple choice type questions. Additionally,students do not get a glimpse of the class response in this method, unless the instructor informsthem how the class voted. Counting of

precisely. Moreover, many textbook definitionsare not accurate or complete for the case of series elements, leading to many misconceptions.For example, students may think that elements must have a node in common to be in series,when they need not! Both elements can be part of a series chain of elements, without directly Page 26.158.6sharing any node. A complete definition states that: a) Two elements are in series if one (andonly one) end of each element is attached to a common node, and no other conducting element isattached to that node (or, equivalently, that a node connects one end each of exactly twoconducting elements); and b) If elements A
