theFBDs of two- or three-dimensional particles, single rigid bodies and structures to be correctlydiagrammed and analyzed from a mechanics perspective. The steps are outlined below and willbe applied to three example static cases.Step 1: External forces/moments Define a coordinate system and draw every external force and moment, including the weight (if applicable), that is acting on the entire mechanical system. Also, find the equivalent concentrated load for any external distributed forces present in the system.Step 2: Separate everything! Separate the particles and bodies present in the system from one another and the ground or any other support and draw all of the forces and moments acting on each of the individual

A survey was conducted in the classesregarding the proposed procedure. The feedback information from the survey was very positive.This paper will also present these results of the data analysis of the student survey.1. IntroductionFor a mechanical engineering program, one of the main learning outcomes is that students candesign machine components. To design a safe component, students are required to apply theappropriate failure theories to evaluate the factor of safety at possible weak points. In order toapply failure theories for evaluating the factor of safety, students must know the

metals and piping industry as a principal engineer have allowed me to promote necessary skills which need to be developed in the classroom so that the students have success upon graduation. c American Society for Engineering Education, 2017 The Retention and Usefulness of Concept Maps as Advance Organizers1. Introduction:A concept map is a type of node-link diagram designed to show the interconnected knowledgestructures that a person possesses in a particular subject area [1]. The diagram consists of nodes,representing key concepts in the given subject area, and links representing key relationshipsbetween those concepts. An example of a concept map of engineering structures can be seen inFigure 1 below

analytically is to assume anelastic-perfectly plastic representation of the stress-strain curve. For the case of torsion, this wouldbe the shear stress vs. shear strain curve as shown in Figure 1. The shear stress varies linearly withshear strain in the elastic region, and reaches a constant value and stays constant in the plasticregion. Sometimes this representation is termed as one of “zero hardening.” However, mostductile materials exhibit strain hardening where in the plastic region, the shear stressmonotonically increases with shear strain. Figure 1There are two analogies to study elastic and elastic-plastic torsion, and are described below.The Membrane Analogy for Elastic TorsionAn analogy between the elastic

This paper summarizes the results of that effort as well as suggestions for those consideringsuch interdisciplinary activities.Background:Much research has been done on the use of demonstrations in various math, science andengineering courses. Some of the literature describes specific demonstration apparatus andtechnique, with the underlying assumption that demonstrations are of value [1, 2, 3]. Manyprojects go a step further and report subsequent student comments, either as verbal responses inclass, special surveys, or the typical end-of-term student evalutions [4, 5, 6, 7, 8, 9]. Studentsgenerally report increased understanding of the technical concept and a better understanding ofthe course relevance. However

This allows D2L to directthe student to the proper revision material required to understand the concept. Note that thestudents only get credit for the quiz if they get the right answer before class time but they areallowed unlimited trials until they get the correct answer.

Since our working memory can only process 7±2 items at one time,learning will be hindered if information to be processed exceeds those limits [1-2]. Based on thisrule, cognitive load theory provides specific instructional guidelines which minimize wastedmental resources and put limited mental resources to work in ways to maximize learning.Cognitive Load imposed on working memory can be divided into two categories: intrins iccognitive load and extraneous cognitive load [2]. As indicated by the names, intrinsic cognitiveload refers to the mental work determined by the intrinsic nature of learning materials that thelearner needs to acquire for achieving

students who did not pass the course, and that the data are typically gatheredfrom multiple assessment events (e.g., exam problems). As such, a student may perform poorlyon one or two of these assessment events, yet perform well enough on others to still pass the course.The learning outcomes for the Strength of Materials course are available in Table 1; the MachineDesign course outcomes are present in Table 2. These outcomes are left broad by design; eachoutcome is intended to encompass several topics within the course. For example, outcome 1 inTable 1, since it deals with axial stress and strain, covers such areas as stress due to forces, Hooke’slaw, pressure vessels, and stress due to bending. Therefore, each outcome may be assessed severaltimes

In trying to solve problems by relating them to a few fundamental cases,the students sacrifice adaptability, and in turn forgo critical thinking.The aim of this paper is to demonstrate a means of building intuition in students throughexperiential learning, so that they can have a gut feeling for how the system works. Experientiallearning is often referred to as ”learning through reflection on doing” 1 .

Thus far we have concluded that the use oftraditional hand-written homework, frequent assessment via quizzes [1], or the PearsonMastering Engineering [2] software for formative assessment did not have a significant impacton students’ performance on exams. It was also observed that neither traditional nor onlinehomework scores correlated well with exam scores, however in-class quizzes did correlate withfinal exam scores. In this paper we hope to look longitudinally at the data collected over thestudy period, as well as the impact of modifications to the Mastering Engineering Online system,specifically the inclusion of the Adaptive Follow-Up modules.

. Survey administration earlyin the term collects formative assessment information for the instructor and sets a baseline formonitoring student learning. The survey items serve as a study guide for course exams andfacilitate student self-assessment. End of course survey responses provide summativeassessment data to evaluate student progress, new teaching methods, and/or curriculum changes.Most knowledge surveys ask students to report their confidence level on a three-point scale thatgenerally breaks down as follows:  1 point indicates little or no confidence they can complete the task.  2 points indicates at least 50% confidence.  3 points indicates 100% confidence they can execute the task with accuracy.This approach allows the

variations on the exact definition ofinquiry based instruction exist. The NRC4 identifies five critical features of inquiry that extendacross all K-12 levels:1. Learners are engaged by scientifically oriented questions.2. Learners give priority to evidence, which allows them to develop and evaluate explanations that address scientifically oriented questions.3. Learners formulate explanations from evidence to address scientifically oriented questions.4. Learners evaluate their explanations in light of alternative explanations, particularly those reflecting scientific understanding.5. Learners communicate and justify their proposed explanations.Minner et al5 performed a meta-analysis of 138 studies to examine the impact of inquiry basedinstruction

Whilelecturing still remains an effective and important way of conveying knowledge, it is critical toget students engaged in active learning through activities such as solving problems, working witheach other, asking questions and getting feedback.To enhance student learning in Statics, researchers at various institutions have explored othermethods for teaching Statics, such as developing concept map and quantifying students’conceptual understanding[1, 2], developing on-line homework or learning modules[3, 4], peer-led-team-learning[5], project-based learning[6], emporium-based course delivery[7].
