There are diverse approaches to conceptual change theories, largelyfocused on the structure and size of knowledge. In this work we analyzed a largeinterview data set from a diverse set of topics in mechanics of materials and consideredour data in light of Stella Vosniadou’s ‘Framework Theory’ of conceptual change.Concepts investigated in interview data include shear and normal stress in axial loads andbeams. We examine the following misconception from our data: stresses only occur inthe direction of an applied load. A theoretical explanation is attempted for thismisconception in terms of epistemological and ontological presuppositions
Reviewer’s Comments1. a) The manuscript is not organzied and poorly written. b) While it can be expaneded to topics other than "mechanics of material," the lack of proper presentation of the methodology makes it difficult to understand to educators outside this filed.2. a) The paper exhaustively discusses the interview process for a small group of students. It concludes with a discussion of their analysis of stresses in a member exposed to three different loading cases. b) This paper will be of interest to those involved with solid mechanics (Mechanical and Civil engineers). c) There are some grammar and spelling issues that need to be addressed. d) The abstract

area.IntroductionThere continues to be considerable interest within engineering education to develop innovativemodes of teaching that will improve student outcomes across a wide range of learningobjectives.1 In order to appropriately assess the efficacy of these techniques a variety ofassessment techniques are needed. For assessment of content knowledge, concept inventoriesprovide a means to assess knowledge in specific content domains. The first concept inventorydeveloped was the Force Concept Inventory, and since then concept inventories have beendeveloped for statics,2 strength of materials,3 engineering mechanics,4 electrical circuits,4 thermaland transport sciences,5 and materials.6,7 As the name implies, concept inventories are designedto test for
institutions working in small groups to develop new, research-basedcourse materials for a sophomore level Mechanics of Materials course. Participants were giveninformational packets that contained previously researched misconceptions specific to theirassigned content area. Groups were given the freedom to create any type of material such asdemonstrations, homework problems or lectures but groups chose to focus on creating hands-onmaterials that were accompanied by a worksheet to guide students through the inquiry process.For example, the torsion group created an activity in which students manipulate a foam poolnoodle and make observations on how a square grid deforms as a torsional load is applied. Audioand video recordings from each group at the

What has just been described is the hope. The reality is that, moreand more frequently, students are expressing a distressingly high degree of confusion anduncertainty with regard to their education. In the “old days” one presumes it was somewhatdifferent. Students had some experience with mechanical systems and realized on their ownthat this was the area they wished to pursue and had a sense as to what aspect of mechanicalengineering most

, particularly with regards to Mechanics-based problems1-4. Providing real-timefeedback on the steps the students follow to solve a problem was identified as an importantaspect to improving comprehension of the course concepts. The bulk of the course materialrequires extensive graphical analysis through the drawing of a Free Body Diagram (FBD), andone drawback to the previous course format was that the students were not equipped with amethod to graphically describe and question the concepts during lecture. An additional issue withunderstanding the course material was the long delay time for receiving feedback that moststudents face when submitting assignments for grading
engineering.IntroductionThe study described in this paper extends ongoing work to identify difficult concepts in thermaland transport science [12] and measure students’ understanding of those concepts via a conceptinventory [5, 6, 7]. The present work focuses on two fundamental areas of engineering:engineering mechanics (statics, strength of materials, and dynamics), and electric circuits, whichare complementary to thermal and transport science. Thus the study was designed with the hopethat commonalities might be found among difficult concepts in chemical engineering,mechanical engineering, and electrical engineering. Indeed, our results suggest thatcommonalities do exist at a very fundamental level.The paper is organized into three sections. The first two sections

. At the end ofthis course students are given the CATS as a posttest. The CATS has been administered in everystatics course since 2006. In the past, this continuous assessment was helpful in identifying fre-quently occurring conceptual difficulties, developing course material according to those difficul-ties, and assessing the success of this material in the classroom. 11,12 Starting in 2009 the teachingmethods in the introductory mechanics course were changed gradually. Tutorial worksheets in thestyle of Tutorials in Introductory Physics by McDermott and Shaffer 8 were introduced and Ele-ments of Just-in-Time Teaching (JiTT) 13 were added in 2011. Three different instructors taughtthis course over the last ten years.2.2 The Concept

For the cohort survey, we adapted questionsfrom three subscales (intrinsic goal orientation, extrinsic goal orientation, and control of learningbeliefs) of the Motivated Strategies for Learning Questionnaire [19]. We reworded each questionto measure students’ general attitudes towards their mechanical engineering courses by replacingthe words “this class” with the words “my [mechanical engineering] courses.” Only the first twosubscales are analyzed in this study.Students were then asked to complete a paper

Student ability isdetermined by the quality of the written answers and by how well they document the processused to solve a problem. However, they provide only limited opportunities to reveal the viewingstrategies used that may give additional insight into how students initially approach the givenproblem.In the present study, we use a within-subject experimental design to investigate the relationshipbetween spatial visualization abilities of students and how students solve specific problems in thearea of mechanics of materials.

the use of a flipped classroom pedagogy to lower the repeat rate in abottleneck upper division mechanical engineering course. Over two quarters (Winter 2017 andSpring 2017), two sections of the fluid mechanics course were taught back-to-back by the sameinstructor at California State Polytechnic University, Pomona; one section was flipped (n = 63),and the other was taught in a traditional lecture style (n = 64). Both sections met twice-a-weekfor 75 minutes. In the flipped classroom, the course material was divided into weekly moduleswith each module focusing on a different topic. Students completed the following activities foreach module: (a) Prior to the first in-class meeting, students were required to watch a series ofvideos totaling
