  • INTRODUCTIONPaper and pencil correspondence courses have been available for over fifty years, andfor motivated students, have been proven to work adequately.Tertiary institutions in Nigeria, in particular, have not only experienced a tremendousincrease in the number of students enrolled yearly but also experience the disruptionof normal school session frequently by strikes. This vast number and the frequentdisruption of normal school session have made it difficult for the few lecturers thereare to lecture and assess students effectively. Hence there is need for an e-learningsolution that enables lecturers to effectively tutor and assess students irrespective ofthe permitted classroom time and the location of the students.With the growth of information and communication technology, the advent of theWWW and the introduction of e-learning technology, the development of a solution toextend the classroom to the internet and educate students on a one-on-one basis, isnow possible. The web-based courseware authoring system is such a solution and alsoincorporates a module for testing the student and hence assessing his performance. Italso has an easy-to-use interface, hence ensuring that any lecturer can be an author ofa courseware with minimal computer expertise.
  • AIM AND OBJECTIVESThe objectives of this research work are to• Build a web- based authoring software for courseware production fortertiary institutions, that will be accessible, easy to understand and usedby lecturers or teachers of limited computer knowledge• Produce software that will allow courseware creators to haveresponsibility for the content of their work, leaving the functionality tobe dealt with by the authoring program• To produce an authoring software capable of offline editing• To produce an authoring software that produces courseware that iseasily accessible by any student’s computer, so that students’ canreview lectures at their own time.• To produce an authoring software that is at par with similar softwarepackages developed in advanced nations• To produce a system for viewing created courseware
  • SCOPE OF THE PROJECTThis project is meant to develop an authoringsoftware that will be used both online and offline.Offline it is used to develop the courseware andadd enhancements that include text, audio andvideo. Hence the courseware will be used togenerate full multimedia.Online it is used to tutor students and assessstudents and show their grades, based on thepresentation of structured course work.
  • LIMITATIONS OF THE EXISTING SYSTEMTo establish the problem statement, the shortcomings of the present method ofknowledge dissemination in Nigeria(the blackboard and paper system) wereidentified:The Traditional Blackboard and Paper System•If a student is not in the classroom whenever a lecturer is conducting a lectureor happens to come late to the lecture, he misses a lot of information thatcannot be easily passed to him by his fellow students. This is because thelecturer, who is seasoned by years and skills and education, knows exactly howto describe a topic and what elements to employ to accelerate understanding.Hence when a student misses a lecture, it becomes very difficult to understandthe topic that was taught.•Traditional blackboard tutorship is not tailored to suit the different learningpaces of the different students in a classroom•The unstable educational environment of the Nigerian tertiary institution,caused by strikes, riots, make it almost impossible for any lecturer to effectivelyteach all the topics in his course scheme of work. This poses a big problem asinformation is mostly relevant in its entirety and not as an incomplete piece.•The present system is not economically focused. This is because a lot of manypeople who wish to be educated but are impaired by distance cannot harnessthe power of education in Nigeria. Distance learning is a very economicallyviable service and such cannot be conducted in the Traditional method ofeducation.
  • OVERVIEW OF ENVISAGED SYSTEMThe web-based courseware authoring system aims to eliminate all theselimitations of the present system mentioned above by being a platform that canbe used by a lecturer/author with little technical skills but basic computerliteracy. Also it is a platform that can be used for the courseware developmentof any topic or course and can be used multiple times instead of just once for aparticular subject or instead of being tailored specifically for a particular course User(s) Online e-learning User login portal form Instructional Courseware Production display of lessons in Lesson Coding of courseware parameters into courseware parameters courseware database Student and author parameters
  • SYSTEM SPECIFICATIONThe top-down design of the web-based coursewareauthoring system (WCAS) in high level model is shownbelow to illustrate the system specification of theaforementioned project.

  • SOFTWARE SUB SYSTEM1) Rootname module: The rootname for every courseware is coined from aconcatenation of the author’s name, courseware title, and courseware topic andcourseware code. This way a unique name is formed for every courseware thatis created irrespective of whether it is by the same author. The rootname isthen stored in the courseware table with its corresponding courseware details(topic, author, title, code).2) Objectives module: This section is linked to the Objectives of thecourseware, thereby stating what is the aim of the courseware and what astudent should be equipped with after studying the courseware.3) Tutorial module: the tutorial module is divided into the lecture notespart and the media part. While the lecture notes (as the name implies) is culledfrom the lecturer’s notes and/textbook, the media files are scenes capturedduring a lecturer’s lecture. The media files help to further emulate theclassroom experience4) Question module: This section displays the question associated to eachtutorial topic. In this module, students are exposed to questions on thecourseware topic and the answers associated to each question supplied as well.It serves as a good revision venue. During the development of the quiz, the quizbuilder in the web-based courseware authoring system wizard is used to inputquestions and save them directly to the quiz table along with their options andthe right answer. These questions are saved against the current rootname

  • PERFORMANCE EVALUATIONThe performance of any software counts alot both to the developer end the user of thesoftware. The web-based coursewareauthoring software was subjected to someperformance evaluation and it wasdiscovered that the software in itsintegration of multimedia and quiz, is anenhancement to some present e-learningsystems. Also it is relatively less expensivethan foreign courseware authoring systemsand very easy to use.
