    The Effectiveness of Aural Instructions with Visualisations in E-Learning Environments

    Based on Mayer’s (2001) model for more effective learning by exploiting the brain’s dual sensory channels for information processing, this research investigates the effectiveness of using aural instructions together with visualisation in teaching the difficult concepts of data structures to novice computer science students. A small number of previous studies have examined the use of audio and visualisation in teaching and learning environments but none has explored the integration of both technologies in teaching data structures programming to reduce the cognitive load on learners’ working memory. A prototype learning tool, known as the Data Structure Learning (DSL) tool, was developed and used first in a short mini study that showed that, used together with visualisations of algorithms, aural instructions produced faster student response times than did textual instructions. This result suggested that the additional use of the auditory sensory channel did indeed reduce the cognitive load. The tool was then used in a second, longitudinal, study over two academic terms in which students studying the Data Structures module were offered the opportunity to use the DSL approach with either aural or textual instructions. Their use of the approach was recorded by the DSL system and feedback was invited at the end of every visualisation task. The collected data showed that the tool was used extensively by the students. A comparison of the students’ DSL use with their end-of-year assessment marks revealed that academically weaker students had tended to use the tool most. This suggests that less able students are keen to use any useful and available instrument to aid their understanding, especially of difficult concepts. Both the quantitative data provided by the automatic recording of DSL use and an end-of-study questionnaire showed appreciation by students of the help the tool had provided and enthusiasm for its future use and development. These findings were supported by qualitative data provided by student written feedback at the end of each task, by interviews at the end of the experiment and by interest from the lecturer in integrating use of the tool with the teaching of the module. A variety of suggestions are made for further work and development of the DSL tool. Further research using a control group and/or pre and post tests would be particularly useful

    Design Patterns and Component Framework for Building RTSJ-Based Real-Time Middleware

    No full text
    The middleware is a software layer located on top of the operating system that uses its facilities, integrates with it, and extends its functionality in order to support the development of effective and reliable distributed systems; however, the architectures of most of the conventional middleware solutions, e.g. Java RMI, do not either offer the predictability required to support the real-time behaviour in these systems, or the reconfigurablity required for these middleware solutions to be applicable in a wide range of distributed systems. Java has a great support for building distributed systems; however, due to its unpredictability, Java does not support building distributed real-time systems and middleware solutions. Hence, this thesis argues that the RTSJ can be used to build reusable and reconfigurable software components and design patterns that have high levels of predictability and reliability. These proposed real-time components and design patterns can be used for building real-time middleware solutions in Java. Therefore, the RTSJ has to be used as a base for modifying the existing reconfigurable and reusable software patterns and components for distribution models. It could also be used to create a new set of these patterns and components, in order to support the real-time behaviour and the predictability in the real-time middleware. The key contributions in this thesis include the presentation of a component framework design model for building RTSJ-based middleware and distributed systems; this framework focuses mainly on the memory model, the communication model of building the components and it also provides the management mechanism of these components, which uses a set of design patterns that integrates with these models. This includes a memory model for the RTSJ components associated with a set of reusability and life-management sub-components that support building real-time components in the RTSJ. Also, we provided a design of a real-time reconfigurable communication component based on the RTSJ that can be used to support predictable low level remote communications in distributed real-time Java applications and we showed how this component could be integrated within the component model as a sub-component, to provide communication services within the component model. Also, we presented our own model of integrating both the framework and the component model within the RMI architecture to provide a reconfigurable real-time Java RMI middleware based on the RTSJ

This summer the celebration began early with a series of concerts. A well attended, well received "Turning 20" jazz concert on September 3 featured outstanding local jazz musicians LoonisM cG lo­hon, Bill Hann, Cannonball Mc­Clure and their respective bands. A special attraction was New York singer Marlene VerPlanck who was accompanied by the McGlohon trio. A concert will also be held with Jim Corr and Friends October 6. Jim Corr will perform Irish music beginning at 11 : 30 till 1 :00. A symposium in Pease Auditorium will be held after­wards with questions from the audience welcomed. Mr. Corr will be discussing the Northern Ireland situations. The perfor­mance will be held in the Forum. An outside concert will be held October 7 with Montana perfor­ming. If you are a lover of country, rock, and bluegrass music, you'll be sure to enjoy this concert. Montana is well known for their music. There will be booths set up around the campus by various clubs selling food and drinks for the students. The fall will offer us all a chance to help CPCC to celebrate its coming twentieth birthday July 1, 1983. We'll keep you informed of more festivities in coming issues of Spark.

The Department of Community Colleges and the Department of Public Education encourage the completion of high school edu­cation, therefore the program is designed to; identify high school drop-outs, lpcate and contact them, and off er help toward their completion of high school education. Individuals are offered the opportunity to attend public high schools. . .if the individual At 3205 Freedom Drive On the West side of town chooses not to attend public school, alternatives are; GED testing, adult high school classes at CPCC (tutors are available also). The program is government funded (CETA), however, funds will be discontinued September 30, 1982. Since the program has been very successful. . .having identified 3,811 high school drop­outs, 665 have been contacted and have responded positively either by mail, phone, or face to face. Out of the persons taking and passing the GED tests at CPCC, 15 percent were brought in by the Drop-out project. . . CPCC (and the other eight community colleges in the state) has decided to continue the pro­ject without government funding. The aim of project is to find out why students choose not to complete high school and off er help. Although the project has been successful, there is still a long way to go, since students leave school for different reasons and no one knows how many high school drop-outs tomorrow brings. In the meantime, anyone seeking help in high school completion, for information contact: Bill Connelly, Director of Drop-out Project. E.T. Room 210 CPCC P.O.

Funches YOUR STUDENT / ASSOCIATION Every student paying the one dollar student activity fee is a member of the CPCC Student Association. The basis of student represen­tation at CPCC is the Program Area Committee (PAC). If you are interested in any of the many extracurricular acti­vities available to you, call the Student Activities Department at 373-6751 or come by Taylor Hall 102 for information. Program Area Committees are groups of students in curri_culum programs which decide how to spend their share of allotted student activity fees. Most of their activities center on their particular areas of study (buying references, special equip­ment, field trips, etc.). If you don't know how to get in touch with these groups, call the Student Activities Depart­ment at the above number. The coordinating committee of the P AC's , clubs, and other groups is called the Student Sen­ate; the chairperson of this group becomes a non-voting member of the college's Board of Trustees. Current topics of business in the Student Senate are: setting up a delegates committee to attend a state conference of the North Carolina Comprehensive Com- CLASS ADS WANTED: Ride from CPCC __,/ to Concord Monday, Tuesday, and Thursday will help with gas. Call Jerry Mauldin. (704) 786-8722 munity College Student Govern­ment Association (NCCCCSGA). The group will be in Charlotte for this conference October 28, 29, and 30. Lynn Bonavita, Chairperson of the Student Senate, invites students who are insterested to contact the Student Activities Department and mdicate such . Bonavita also wants the student body to know that the Student Senate will be holding its internal elections at its first meeting in the Fall Quarter's first week. The specific date has not yet been set but will be posted on the marquees on campus. Another item for student clubs or organizations to note is the availability of resources offered by the staff in the Taylor Hall 102 office. Groups needing supplies, typewriter avail­ability should come to the lobby of Taylor Hall or call 373-6665. October 7 is slated for the Fall Quarter Activity Day on campus. The day is set aside for clubs, P ACs, and other organizations to show other students what they do and try to interest them in joining. Displays, hands-on acti­vities, artwork, sales, food, and fun and music are all present. This Fall Quarter's theme is "Turning Twenty" as next July 1 is CPCC's twentieth birth­day. Montana, a well-known electric bluegrass and country band will be on hand from 11 :30 til 1 p.m. Location will be on the mall between Kratt and Mecklenburg Halls. (See the article 01.1- other coming events elsewhere in this issue.) NOTES Literary Magazine Shows Promise The student literary magazine, formerly known as the Paul At­well Memorial Literary Magazine, will be available before Fall Quar­ter begins. When classes have begun students can pick up their free copy in the Spark distri­bution stands (tripod with yel­low box). This issue is called Impressions and contains poetry, prose, and art produced by students over the past year or so. Chapie Chapman, the student preparing the magazine for print said, "We are now ready to take 64 pages of very good work to our printer. It has been a real treat being able to compile this year's book. I believe it will certainly uphold the tradi­tional quality and impact of previous issues." Past issues have been well re­ceived by the community as a magazine featuring beginning wri­ters and occasional contributions by well-known writers. These have included, among others, Paul B. Newman, Queens College English faculty member; and Tom Heffernan, former Wri-­ter in Residence at CPCC. Campus Ministry Offers Helping Hands by fe rry Wilson Spark Editor In the hustle and bustle of every­day life, one acquires problems that seem insurmountable when faced alone. The United Campus Ministry will be there to help in any way they can The Ministry is concerned with people finding a deeper and more meaningful spiritual life through prayer, discussion, scrip­ture study and fellowship. The Ministry is developing programs for students and faculty that would assist in the develop­ment of the individual, with a belief that living and learning can be an exciting experience. Under the United Campus Ministry are three clubs, Baptist Students Union, Catholic Campus Ministry and the Christian Science Group. Each club will remain as separate entities but will coordi­nate some efforts under the leader­ship of David Upshaw, the Campus Ministry Coordinator. Working with Upshaw, the Ministry includes: Sister Mary Agnes Solare, Don Rogers, Chuck Kirby, Jim Kelly, Merritt Green­wood and Mark Key. A Campus Minister will be in the Drop-In.Center on Monday through Friday, available for appointments or for fascial con­versation. For futher information, call David Upshaw at 333-8099. Clergy group working with United Campus Ministry from-Office of Public Information The setting is an opulent sitting room, complete with mahogany coffee table and leather couch. Presidents of two leading financial firms are discussing the wisest investment opportunities for the l 980's. Look around and you're in your own living room, taking a course to be offered this fall by Central Piedmont Commu­nity College on WTVI, Channel 42, and Chalrotte Cable 3. The course, "Personal Financial and Investment Planning," features 12 televised interviews with financial experts that are conducted by Venita VanCaspel, financial planner and author of three books on investing, including Money Dynamics for the 1980's. The TV programs are titled "The Moneymakers" and stress achievement of financial success despite inflation. The stock market, financial advisors, tax laws and shelters, real estate, energy investments, precious metals and gems and insurance will be discussed and analyzed. In addition to watching one half hour TV program weekly and reading for a half hour each week in a booklet accompan­ying the series, students will attend class weekly. In class, Accounting Instructor Pat Butler will show gra­phics and slides that illustrate the television interviews, answer questions and pay special attention to each student's financial planning efforts. "Most people spend more time working on their yards than on their finances," Pat says, "and yet only two out of every 100 people reaching 65 are financially independent." The class discussions will offer an objective survey of mon­etary opportunities, he says: "In most of the traditional places where you ask financial questions, there's often a pro­duct involved." Pat has taught accounting at CPCC for four years, and he holds bachelor's and master's degrees in business administra­tion. He has worked in investments, insurance and financial advising and has served as chairman of the Mecklenburg County Council on Aging.

Ms. Wilson has been a student for three years, taking classes when she can, and is interested in transferring as a Communications or Journalism major. She is a member of the Writer's Institute of America and plans to make journalism her career. Since her editorship began Ms. Wilson has met with administrators and staff members in order to form a viable plan to make the student newspaper one which students can look forward to for useful informa­tion and interesting features. Currently this newspaper is pubiished three times in- tlle Summer Quarter ( one of those being mailed to all registered students.) Fall plans include five issues (two of these will be mailed) and possibly advertising by local businesses. Cl11b and u_r_ganization Notes SME-cPcc Mechanical and Manu­facturing Engineering Technology students have formed a student unit of the Society of Manufac­turing Engineers (SME). The focus of the club is on educational and career opportu­nities in manufacturing and design engineering. Special events plan­ned include plant tours, speaker presentations, educational semi­nars, and other events. The July meeting featured Mr. Joe Dumontier, Senior Vice-Pres­ident of Pelton-Crane who spoke to students on tool and die mak­ing. The club will hold its mee­tings once per month. M~eting times and campus locations will be posted in the Mechanical Draf­ting and Mechanical Engineering Technology labs. Full-time students enrolled in a mechanical engineering techno-logy program, or those who dem­onstrate a sincere interest in the field of manufacturing engineer­ring are eligible to apply for stu­dent SME membership. Mem­berhip application forms are avai­lable in the Mechanical Engineer­ing Technology lab (GA 249) and in the Mechanical Drafting lab (CE 409). For more infor­mation, please contact the club's co-chairman Doug Knox at 563- 2758. Phi Theta Kappa-by James Thomas Phi Lambda Chapter of Phi Theta Kappa fraternity is now actively seeking new members. The national honor society for junior/community colleges meets bi-weekly on Thursdays at noon in MH 213. The society is for students who have a grade point average of 3.25 and are interested in iss­ues of the day and involved leadership and service. BELK GRANT TO AID PROGRAMMING From the Office of Public In­formation- Laura F riedlein A 100,000 donation ~resented to CPCC by the Belk Foundation August recently will be used to improve instructional programs. A study in progress to deter­mine the best possible use of the grant indicates that the greatest need is computers for program­mjng and data processing students who are training for an eager job market. The check was presented at a luncheon here by John Belk, chairman of the board of Belk Stores Services, former mayor of Charlotte and a trustee of the Belk Fountadion; and by Tom Belk, president of Belk Stores Services and chairman of the Belk Foun­dation. Department Name Changed A new distribution of respon­sibilities in the college transfer/ liberal arts area is expected to give faculty members more individual attention from their supervisors and generate additional, more innovative course offerings. The former Language and Humanities Department has b~en renamed Writing and Humanities and include courses in composi­tion for freshmen and sopho­! llores, technical writing and humanities. Foreign language and :;pee ch were reassigned from that depart­ment to the reading department, headed by Terilynn Turner, to create a more balanced workoad in each department. Turner's department is now called the Reading, Speech and Foreign Languages Department. · The lparll Central Piedmont Community College Student Publications Agency Office of Student Activities P. 0 .

Permit Number 1177 UNITED WAY CAMPAIGN ASKS STUDENTS' HELP The CPCC Student Association by a vote of its coordinating body, (Student Senate) has endorsed this year's United Way campaign by encouraging individual students to make a pledge and asking the more than forty student organi­zations to consider fund-raising projects and contributing part of the proceeds from them. CPCC United Way Chairperson Mitchell Hagler said he had not yet received this year's goal but estimated that "our goal will be somewhat higher this year. Since the economy is tight, it may be harder to reach that goal. Our president, Dr. Richard Hagemeyer, is chairing the higher education section this year. Naturally we want CPCC to set a good exam­ple." Some Facts About the United Way- Consists of 32 local and state agencies providing over 178 services. Approximately .91outofevery.91 out of every 1 is returned to the community through agency services. A few of the United Way agencies include: American Red Cross Association for Retarded Citizens Charlotte Speech and Hearing Center Council for Aging Epilepsy Association Family and Children's Services Metrolina Association For the Blind Florence Crittenton Services Goodwill Industries Mental Health Association Hagler pointed out that this is the first year that the CPCC effort has included an appeal to the students.
