Using an HMD, the user viewsthe physical world through transparent glass capable of reflecting virtual information, oralternatively, using the two small displays in helmet that display a video stream of theenvironment. While providing an immersive experience, they are prohibitively expensive formany universities. An alternative to HMDs is to use smart mobile devices that serve as awindow through which to view the augmented world. By pointing the device at an area ofinterest, the video stream from the built-in camera can be sent to the display, providing the userwith a mediated view of the world.

We used the varimax rotation method with Kaiser normalization.2.3 Cluster AnalysisAfter the factors or components underlying the different conceptual categories have beenidentified, it is possible to derive scores for each student on each factor. We used hierarchicalcluster analysis, using the Euclidian distance as a proximity measurement, to classify students’factor scores and to group students in different clusters reflecting their responses to conceptualassessments. The number of clusters was determined by inspection of the dendrogram, a displayrepresenting visually the distances at which clusters are combined
. The cadets have found these topicsengaging and have participated with excitement in the projects and discussions that centeraround the topics. The cadets enjoy discussing and learning about the various topics in computerscience, especially the discussions on networking. Using the networking project provided byNICERC, the cadets became the nodes and lines of communication while others acted as the“Man in the Middle” or the “Denial of Service.” This enhanced their understanding of sendingmessages through cyberspace and threats that exist.Cyber Science is one course which has been accepted readily and enthusiastically by both theCyber Science instructors and the NOMMA administration. This excitement is reflected in thecadets’ interest and desire
different courses of the sametype. The lack of transfer is likely due to multiple factors. Students may have forgotten some of thematerial learned in a previous course; students may not perceive the connections; students may seethe connections but are unable to use the material in meaningful ways in a different context; or thepedagogical approach used by instructors may not be conducive to transfer.3Approaches used to facilitate transfer of learning include the use of reflective writings,contextualization of learning experiences, and application of learning to real life. Multiplestrategies have been suggested to encourage transfer 3: making the need for transfer of learningexplicit to students, advising students to take courses in the appropriate

UMLUnified Modeling Language28 widely known as UML is a software engineering tool used formodeling software systems. Fundamentally it is used as a tool for analyzing, designing andimplementing software intensive systems. UML provides a visual representation of the systemwhich reflects the standard and interactive organization or system’s elements. From thebeginning till now, there are several versions of UML have been evolved and UML 2.0 is usedfor the modeling of our system. UML offers two types of system modeling, one is structural orstatic modeling which require the

significant proportion ofstudents to fail in exams, which consisted mostly of simulating the execution of thealgorithms for a given input. Usually, students made two types of errors: simple involuntarymistakes and errors that reflect a lack of understanding of the algorithm. After applying themethodology, the former were less common, and the latter were infrequent. We started usingthe methodology in the II semester of 2010 (in our college, I semester goes from March toJune and II semester from August to November). Tables 1 and 2 show the average grades forTest 1 applied during the II semester of 2009-2010 and the I semester of 2010-2011 (beforeand after applying the methodology, in each case).

9 different sessions of this class taught by 6 instructors. Two course modules were delivered to one session of CS1428 and the following week the students received the survey and the results were compared to the survey results from students who did not receive the modules (under the same instructor and different ones as well). All surveys were conducted within a10 day window around the end of November. In one module, the focus was on Computer Science big picture and the other focused on cyber warfare (as explained above in details). Another aspect that was not reflected in the results was the amount of interest the student developed from these modules. The students approached the faculty who delivered those modules after class and described

The convection simulation (Fig. 6) shows fluidmolecules removing energy from solid molecules as students vary the wind speed.Figure 6.Molecular simulation of convection heat transfer.The radiation module (Fig. 7) explains the concept as the interaction between moleculesand photons in our study. The radiation simulation depicts a water molecule absorbing,reflecting, or being transparent to different wavelengths of radiation. Students are able tochange the temperature of a solid object that acts as an energy source. As students changethe temperature of the source the amount of energy emitted increases and thewavelengths of the energy change
, the graduate student wasable to take MOOC courses for credit and most likely learn material that would have otherwisebeen unavailable on campus. The weekly meeting with his faculty advisor required the studentto summarize and distill information from the MOOCs as well as reflect upon the educationaldelivery mechanism’s effectiveness. From this experience, the student also determined that therecan be a variety in quality and level of rigor with each MOOC; thus, he would recommend thatmultiple MOOCs be included in a course plan to increase the likelihood that valuable learningcan take place across courses. For example, though the E-Learning and Digital Cultures courseappeared rigorous in the description, the actual execution of the course was

The robotchosen for this project was the Lynxmotion Rover robot1 (Figure 1). The robot chassis wasmade from heavy-duty anodized aluminum structural brackets and laser-cut lexan panels. It usedfour 12.0 V dc gear head motors and 4.75 “tires and wheels”8

Related tothis, the instructor suggested that we show the thread length for response (or answer). He alsowanted to know, if an answer was good, why were there more answers?

To the extent possible, the teams also reflect diversity of major, gender, and evennationality. Teams are shuffled and students are assigned to different teams from one assignmentto the next, in order to maximize networking in the class. Sometimes, students are allowed tomake up their own teams, but diversity is still required. For example, in a Statics class of 25students in Fall 2011, students divided themselves into 5 teams, each with two men and threewomen, from at least two majors, most of whom were mechanical and chemical engineeringstudents, with a few civil and electrical engineering majors.Each team is

Section 4 presents tools for analyzing and interpretingresults, and writing research papers. Our reflections on this work and future research are indicatedin section 5.3 Literature Search, Review, and AssessmentWhen students embark on research, often they have no clear cut ideas about which area or topicsthey want to investigate. At best they will have one or two key phrases (e.g., comparative genomicanalyses) to begin their exploration. This is also true with seasoned researchers who want to forayinto emerging areas (e.g., bigdata visual analytics). A first step in this scenario is to get acquaintedwith the

While this was a pleasing observation, it did require us toreconsider the depth of some material, and perhaps consider some different techniques in thefuture, as the interest is continuing to expand. We are strongly considering offering two variantsof the course: one course would be the existing data mining course as an elective for thecomputer science major, with a prerequisite of taking a course on data

An inspection of the Q-Qplots and histogram graphs for the remaining five variables (v2, v4, v5, v8, and v12) forwhich the confidence interval were not computed (variables not normally distributed) showone or two outliers. These outliers could be a reflection of the type of research project andthe student’s academic level.Table 2 (Evaluation 1): CISE REU Survey Constructs Differences df Std.

audience time only masked the significance of the usability data with an activity thatdid not reflect usability, but merely represented passive reception. All tasks were re-analyzed and certainprocedures were modified to focus on activities that indicated differences in usability. The testing timeoverall has been reduced from the initial design of several hours per user (four platforms, nine tests) toabout 20 minutes per platform or about 45 minutes for a complete single user experience (two platforms,three tests). It would have been difficult and expensive to recruit a statistically significant number ofusers to complete a set of tasks lasting several hours per user.One of the difficulties of measuring cross-platform occurs when the app
detection tools, such as Moss [10], may also be integrated for instructors as they become necessary. Moreover, besides record every single operation of students and program execution settings, it is possible to store copies of students’ code to understand their progress. The information will be valuable for future studies on how students learn and debug their programs.

, this imperfection inmeasuring can convincingly reflect the real overhead in a real system.5.1 Hash FunctionsIn the first set of experiments, we measured the H(VM) with several major CryptographicHashing Functions [12]. We chose different hash function to be able to compare them and chosethe best match for our proposed Architecture. Results of H(VM)’s Execution time are shown inthe Table 2. As seen from the results, the CPU processing time of hashing is basically linear tothe size of the VM templates. SHA-384 and SHA-512 has similar processing time due to the factthe construction of the hashing are very similar. An interesting to note was SHA-256 processtime is actually longer time than SHA-384 and SHA-512. This is because SHA-384 and SHA-512
andBriggs developed the MBTI tests for understanding preferences, and successors to the MBTItest3 are still widely used to today. Similarly David Kolb’s experiential learning theory4 promotesmultimodal learning based on a cycle of concrete experience, reflective observation, abstractconceptualization and active experimentation. All of these experiential learning modes can beenhanced by engaging the students with interactions with hardware modules. Small low-costcomputing platforms, such as the Arduino microcontroller and related devices, provide a way tophysically encapsulate many of the learning concepts related to IT and students can program,control and interact with these systems in a very direct physical fashion, involving not only sightbut
. These software enabled devices allowed students to take notes,draw charts and diagrams. Afterwards the results were measured through student feedback. The Page 26.1592.3results of the experiment were satisfactory as more than 85% of the students thought that usingthe tablets contributed positively towards their active learning experience. Instructors observedthat the level of interaction and enthusiasm increased greatly among students. While it is difficultto provide accurate result values that reflect the amount of increase in student performance in theclassroom, the high level of attendance, which was observed, was certainly a good indicator
. Despite thebenefits of an approach teaching problem-solving skills first, the transition from pre-programming problem-solving courses to courses in which students should master a full-fledgeprogramming language remains a challenge 18, 22. This is reflected in the number of students(44%) who did not have an acceptable performance in either concepts or skills (Figures 4 and 5).Even though those students had passed a previous problem solving course, they find thetransition to a learning environment that uses a full-fledge programming language like Javadifficult.According to Mayer 17, in addition to the cognitive and metacognitive aspects of problemsolving, other aspects like motivation and engagement are also important determinants of studentsuccess
