created a significant database of responses for questions about algebra. However, thestudents struggled with some of the complex structure of AIML beyond one for one matching ofresponses to algebra questions. Furthermore, the students had difficulty with the online teachinginterface for the chat-bot.Based on the positive response of students to the chat-bot and the difficulties encountered inusing the available training utilities, a new platform for the chat-bot was developed by Dr.Crown (www.crown.panam.edu/chat) as shown in Figure 1. The new Anne G. Neering chat-botwas developed to interpret a majority of questions and responses given in existing AIML files.This would enable the engineering chat-bot to build onto one of several chat-bot
better their understanding of the concepts instead of justlearning enough to get the correct solution.IntroductionThe use of technology in the classroom has reduced the work load for instructors and offers thepotential for improved learning, but many time the use of technology alone fails to grasp the at-tention or interest of the students enrolled. Interactive demonstrations, whether computer-based orhands-on, have been shown to enhance comprehension especially when dealing with higher levelconcepts often encountered in science and engineering courses [1–5]. Though hands-on activitiesare likely more effective for student learning, in class demonstrations of simulation tools related to

IntroductionSmart devices are growing exponentially, and our everyday life has changed dramatically withthe advent of the Internet and networking technologies. Related to these technologies, oneemerging entity is the IoT (Internet of Things). This is a developing concept of making an opennetwork of devices equipped with sensors and RFIDs (radio frequency identification) aimed atinterconnecting all things electronic to make them more intelligent and programmable.According to Cisco, a leader in IoT and supported by IEEE, about 20 billion machines anddevices could be linked by

The use of traditional laboratory has been adversely affected over time as a resultof rising cost of laboratory equipment and increasing number of students’ enrolment intoschools 1 . As the number of student participation rises, there is a need for a complementaryprovision of platforms for experiments to be performed or at least perform them with a closereplica of the actual laboratory experience.Virtual laboratories are software applications that use the theory behind the experiment tomodel a laboratory setting. Virtual laboratories have a number of advantages. Firstly, withvirtual laboratories, the student can repeat a particular experiment multiple times withdifferent

Recommendationsfor future efforts focus on incorporating more complex C/++ applications concurrent with FPGAdevelopment. Page 24.546.21 IntroductionThe “Internet of things”1 challenges engineering educators to deliver content and skills while en-gaging students in hands-on projects that employ a variety of embedded computing platforms.From proprietary to open source hardware and software, from microcontrollers to embedded OSdevices, students today have an
such as concept inventories (CIs). For example, as Nehm & Schonfeld demonstrate,the multiple-choice Concept Inventory of Natural Selection measures whether studentsunderstand “pieces” or elements of the theory of natural selection, but does not provide anymeasure of students’ abilities to assemble the pieces into a coherent and functional explanatorystructure 1, 2. Moreover, multiple-choice CIs introduce significant validity threats as they areconstrained to “either-or” forced-choice (“misconception” vs. scientific key concept) itempreference and do not typically allow the detection of students who harbor “mixed models” ofcorrect and incorrect conceptions 1, 3-8. Thus, constructed response (CR) assessments that capture students
Appendix AAssessment of the Blended Learning ImplementationThe performance of the blended learning implementation of the electric circuit analysis coursewas analyzed along two dimensions. First, student performance in the course was compared tothe previous semester when it was taught as a traditional lecture course by the same instructor.The exams in both semesters were comparable in difficulty, and analysis of the studentpopulations showed no significant differences between them. Students demonstratedsignificantly better performance in the blended version of the course, as shown in Figure 1. Amarked change in the distribution of student grades was also observed, with the number ofmarginal and poorly performing students significantly reduced

The program has been highly successful incapturing the interest of the participants and has led to increased retention of these students inengineering.IntroductionRecruiting and retaining students in engineering programs is a national problem that has beenaddressed in many, varied ways.1 Many universities offer bridge programs for incomingfreshmen to increase their success in engineering programs.2,3 These programs are oftendesigned to improve skills in fundamental courses such as mathematics and English as well asacademic strategies. In contrast, the University of South Alabama offers

This poses a problem in the softwareindustry, as there is generally a lack of knowledge of Software Verification and Validation(V&V) benefits and a shortage of adequately trained V&V practitioners. This project, funded bythe National Science Foundation –Transforming Undergraduate Education in Science,Technology, Engineering and Mathematics (NSF-TUES) grant, has objectives to transform arequired course in Software V&V offered to Software Engineering students at Author’sUniversity and disseminate it to the academic and professional communities.

Still others continue to report no difference.5,6In considering the inconsistent findings in the literature, one must also consider the variableresearch designs and sample populations used within these studies.

student's perspective - the predominantdifference between on-line courses and face-to -face courses is probably time management,stating that in “on-line, there's no teacher taking roll. ... You've got to be prepared to beorganized, and you've got to keep up with the work.”1. This perspective was echoed in previouswork by the authors2, 3 and also in the research reported here in which students said: I’ve learned, from taking on-line courses, that getting work done becomes second-nature more so than in face-to-face classes I have developed the ability to not procrastinate during the semester and that has carried over into my daily life.In designing on-line courses, the instructor must enable students to engage in a
persistence of unfilled posts in programming and ITfields originates more from business hiring practices and a perceived “skill deficit”among degree holders and potential applicants (2, 5). Regardless of the veracity of theclaims, researchers have been working during the last 15 years to identify and overcomepotential barriers to careers and study in computer science. Following recommendationsfrom national reports (1, 15), mediation efforts have adroitly focused on K-12 education,measuring potential bottlenecks in the pipeline for programmers (4, 22). These effortshave also spurred novel solutions to increase interest and skill in computer programmingamong students, ranging from content-based solutions to inventive graphical learning

If the program does not recognize the subjectline as a problem for which it has a key, it sends an email to the student with the list of knownsolution files and the general grading program instructions. If the subject line is recognized,students then receive email feedback on their work consisting of a list of discrepancies betweentheir drawing and the answer key (Figure 1), and two jpg files containing pictures contrasting thetwo solutions (Figure 2).Figure 2A shows the
communities to be agents of change. Forexample, various communities in countries such as Egypt, Tunisia, and Libya are harnessing thepower of mobile technology and leveraging social media to maintain a voice in the midst ofpolitical oppression. Social media have been cited as the driving force of the uprising orrevolution of 2011, better known as the Arab Spring,1, 2, 3 in which many used blogs, Twitter, andFacebook to facilitate social activism, defuse disinformation, and effect change. Similarly, amore casual example is the use of mobile technology by fishermen, which decreased pricedispersion, eliminated waste, and enabled new modes of cooperation, through the sharing ofinformation regarding promising fishing grounds and rescue at sea.4, 5
Point presentations with embedded audio files.IntroductionIt is suspected that lecture delivery methods which incorporate more media would appeal to moretypes of learners. There are three basic types of learners:1. Visual, or those who think and learn in pictures2. Auditory, or those who learn by hearing3. Kinetic/Tactile, or those who learn by moving, touching, and doingHypermedia technology has been shown to have the potential to accommodate learners withdifferent needs through its rich environment1, suggesting that when more senses are used by adigital media, a greater variety of learners can be accommodated. By designing lectures whichincorporate more senses, it may be possible to relate to a larger percentage of the class via their

The alumni had graduated in the early 1980’s developed a highly successfulindustrial control company that provided service to the chemical, mining, oil, petrochemical, gas,and automotive industries [1]. The alumnus was interested in supporting the development of acourse that emphasized the design of programmable logic controller (PLC) based systems vital toa wide range of industries and to support the ongoing demand for engineers educated inindustrial control concepts and applications. Further, the alumnus pledged financial support todevelop a physical laboratory and the required instrumentation to
maintain quality while maximizing university resources.Meeting the Online Growth Demands The research on how educational institutions are handling the growth of onlineenrollments is minimal. Burruss, Billings, Brownrigg, Skiba, and Connors (2009) remarked onclass size and “minimal research at the postsecondary level” (p. 38). The authors go on to saythat the number of online students is increasing and with a shortage of faculty class sizes areincreasing. Colwell and Jenks (2004) added “Faculty can face pressures from administration to“maximize” class sizes in online courses to make them more efficient or profitable” (p. 1). There is concern from educators about the quality of education when class sizes areincreased; however, the

These lessons will be applicable to other types of engineering courses where computing is being introduced.IntroductionMany engineering curricula around the country are re-evaluating their introductory computerprogramming requirements. Realizing that the standard introductory programming courses nolonger appropriately complement the education of systems engineers (i.e., Textile Engineers (TE)and Industrial and Systems Engineers (ISE)), a new Computer-Based Modeling for Engineerscourse (TE/ISE 110) that integrates critical thinking and problem solving within a computationalthinking framework has been developed 1–3 and taught for

Students are expected tohave already completed the mineralogy and chemistry courses as pre-requisites for this course.The course may include graduate students who are meeting deficiency requirements, or desire torefresh their background knowledge in Igneous and Metamorphic Petrology. Enrollment in thiscourse typically varies between 11 and 22 students, but in the last three years the enrollment hasmoved toward the upper level of this range varying from 18 to 22 students.Course GoalsThe goals for this course have been divided into three categories: (1) Technical skills which pertain directly to becoming proficient in the subject of Igneous and

In the Fall 2011semester 33 undergraduate students were enrolled, 31 of them choose to participate in theself-directed lifelong learning experience. The course teaches principles of controlsystems, process block diagrams, feedback control, process monitoring, DOE, SPC/SQC,and Taguchi methods. The class meets on Tuesdays and Thursdays for 1 hour 15 minutelong sessions. Following each class meeting, students were assigned homework. DuringFall 2011 semester a total of 22 homework assignments were given. The total weight ofthe homework assignments was 25% of the course grade. The course also included twoseparate projects, both of which
