El Haddad, Samy S. Abu Naser- ADO-Tutor: Intelligent Tutoring System for leaning ADO.NET   EUROPEAN ACADEMIC RESEARCH - Vol. IV, Issue 10 / January 2017 8811 INTRODUCTION  The beginning of ASP back in late 1996 when ADO 1.0 was released representing a new way of dynamically reclaiming data from a database. Though ADO was at its early childhood then, and was something of an offshoot of DAO and RDO, nonetheless it represented a new bold direction. Each subsequent version of the technology takes us one step closer to ADO 2.6, when development finally came out. At this point, evolving from the shadows came out the most radical framework to date – .NET, with it the very powerful and complete ADO.NET [1,2]. This new data module, presented with .NET, offered an exciting new method to data access. However the methods, and logic used to connect to databases with ADO.NET weren’t shockingly different from those used with its ancestor, ADO.NET had a lot to bargain. What was sole about this technology was the construction underneath it all, its powerful methodology to data organization, and the elasticity in the next level of data-presenting devices [3]. ADO, for its time, was definitely successful. Even though the re-releases of the technology had not indicated intense change for ADO, it attained what it had to within its own construction. Though, it was repeatedly overwhelmed by problems that fenced its management of disengaged data stores, and functioning appropriately and tersely with XML. This is where ADO.NET came in – these are the two things the new technology simply succeeds, as XML is the essential constituent of the whole .NET Framework! ADO.NET was simply produced to solve all the lacks found in ADO, and offers developers with the power to attain more with less [4-6].  ADO-Tutor was designed and developed using ITSB authoring tool [23]. Ibrahim A. El Haddad, Samy S. Abu Naser- ADO-Tutor: Intelligent Tutoring System for leaning ADO.NET   EUROPEAN ACADEMIC RESEARCH - Vol. IV, Issue 10 / January 2017 8812 The goal of our intelligent tutoring system was to help users learn easily how to use ADO.NET and to connect to databases. The benefits of Intelligent Tutoring Systems include[7]:  ITS are available at any time of the day, even late at night before an exam.  ITS provide real-time data to teachers and developers looking to enhance their teaching methods.  ITS reduce the dependency  on human resources  ITS help students more in understand material by permitting them to first state what they know, then by outfitting responses accordingly  ITS afford educators the chance to produce individualized programs due to their tailored nature.  ITS harvest higher exam marks than traditional systems, particularly in students from special education, non-native English, and low-income backgrounds.  ITS Provide immediate customized feedback, individual task selection, on-demand hints, and provision for mastery learning.  Some of the criticism of Intelligent Tutoring Systems includes:   ITS is difficult to measure its effectiveness   ITS immediate feedback and hint sequences fail to improve deep learning in students.  ITS fail to ask questions of students that may clarify their actions.  ITS implementation may be hard to defend to an administrative staff.  ITS evaluation often hard, costly and time consuming.  Human tutors are currently better than ITS in providing proper dialogue and feedback.  Human tutors are currently better than ITS in interpreting and adapting to different emotional states.   Ibrahim A. El Haddad, Samy S. Abu Naser- ADO-Tutor: Intelligent Tutoring System for leaning ADO.NET   EUROPEAN ACADEMIC RESEARCH - Vol. IV, Issue 10 / January 2017 8813 LITERATURE REVIEW  An Intelligent tutoring system provides customized feedback instruction to students [23,33].

ITS ARCHITECTURE  Figure 1: Architecture of ADO-Tutor Ibrahim A. El Haddad, Samy S. Abu Naser- ADO-Tutor: Intelligent Tutoring System for leaning ADO.NET   EUROPEAN ACADEMIC RESEARCH - Vol. IV, Issue 10 / January 2017 8814 Modern intelligent tutoring system architectures consist of four modules as in Figure 1. The four modules are represented normally as the domain module, student module, tutoring module and the interface module[7,12]. The domain module is how the material is represented and stored to be ready for transmitting to the learner. The domain module is connected to the student module and the tutoring module. The student module represents the learner’s conduct such as his learning style, motivation level, his interests, and profile. All the student conduct is logged into the system and used for reasoning and adapting the domain module to the learner’s needs [15]. The tutoring module acts as a computer-generated instructor, presenting the material in an proper order, according to the student learning style and his skills. This is a collaborating process and this module has the task to clarify the concepts to the learner given few points of view and supportive all the learning procedure [19]. With the capacity to interconnect and cooperate with the student, the interface module has an enormously significant job. If one ITS have great tutoring, student and domain modules, but the interface module is very deprived, the ITS will not be operative because the interface is the front of whole system and has the aptitude to capture all the care of the learner [21].   DOMAIN MODEL ARCHITECTURE  The domain model of ADO-Tutor includes the following material:  Lesson 01: Introduction to ADO.NET  Lesson 02: The SqlConnection Object  Lesson 03: The SqlCommand Object  Lesson 04: Reading Data with the SqlDataReader Ibrahim A. El Haddad, Samy S. Abu Naser- ADO-Tutor: Intelligent Tutoring System for leaning ADO.NET   EUROPEAN ACADEMIC RESEARCH - Vol. IV, Issue 10 / January 2017 8815  Lesson 05: Working with Disconnected Data – The DataSet and SqlDataAdapter  Lesson 06: Adding Parameters to Commands  Lesson 07: Using Stored Procedures  STUDENT MODEL ARCHITECTURE  The system sore the student data in a database, and by recording his own name, number, last session time and date, lesson learned, current score, overall core and all the details of the student or the learner of the system.   TEACHER MODULE ARCHITECTURE  The storage information about the user can used to customize the feedback to display the relevant information to students about the educational level and stage passed the student and how much he/she studied, and difficulty level reached. For example, when the student's current score out of 100 reaches 75 or more, the tutoring module takes the student to next level of difficulty and give the student a notification about the score he/she achieved.  USER INTERFACE MODEL  The tool used for building the ADO-Tutor has two interfaces in one.  The first is the teacher interface, where he/she can add the lessons, questions, answers, level of difficulties, basic ITS data, Basic student data, and customize the coloring of the screen of the system. The second interface is the student interface where he/she is allowed to the leering material screen, questions screen, statistics about his performance screen as seen Fig 2-Fig5.    Ibrahim A.

Ibrahim A. El Haddad, Samy S. Abu Naser- ADO-Tutor: Intelligent Tutoring System for leaning ADO.NET   EUROPEAN ACADEMIC RESEARCH - Vol. IV, Issue 10 / January 2017 8817  Figure 5: This is a special notification about the progress of the student  EVALUATION  DO-Tutor was presented to a group of specialists in the field to evaluate it and gives us feedback about the design of the system, the material offered to the learners, easiness of use, quality and expressiveness of the exercises and their relation to the lessons given to the learners. The results of the evaluation were promising. We will do some more evaluation in the near future to check the effectiveness of the ADO-Tutor and take into considerations the comments of the evaluators.  CONCLUSION   In this paper, we created an intelligent tutoring system called ADO-Tutor for teaching database connection. ADO-Tutor was designed and built using ITSB authoring tool. Through what has been reviewed we have created a simple and easy way to explain the material instruction, while ensuring that the student take advantage of through questions and find solutions for those who could not answer. An initial evaluation was done by a set of specialist in the field and the results were promising. In the future, we will increase the lessons to cover a greater range of educational material.
