Abstract
In this paper, we highlight on the importance of teaching Object-Oriented Programming(OOP) to students. An analysis is carried out to determine if Mauritian Universities are emphasing sufficiently on teaching OOP to their students. The undergraduate courses consisting of at least one computer programming module were considered in the analysis. These courses were offered by the university of Mauritius(UOM) and university of technology(UTM) in 2015.
Keywords: Object-Oriented Programming (OOP), universities, computer programming, undergraduate courses and digital economy.
Introduction
“Many software development organizations are adopting object-oriented methodologies as their primary paradigm for software development. The object-oriented method appears to increase programmer productivity, reduce the overall cost of the software, and perhaps most importantly creates software that promotes reuse and subsequently is easier to modify. Consistent with the change in industry, many universities and industry training organizations are currently in the process of integrating object orientation into their curriculum. There are several approaches including horizontal integration (integrating a small dose of the object orientation into many courses) and vertical integration (having a large dose of the concepts in a single course).” (Clark & kipper, 1998)
Teaching object-oriented has become an essential part in computer science education (Rosenberg & Kölling, 1999). The most common method to introduce computer programming to students at schools and universities is to use an easy programming language and at a later time, move to another difficult computer paradigm concept. Therefore, procedural programming concepts being easier to OOP are introduced to students at first and at a later time during the course, the same students are introduced to OOP. Today, this is slowly changing. Many researchers and teachers (Kölling, 1999) recommend to teach object-oriented at first if the aim is to teach them OOP. Object-oriented is more likely to be used in the industry (Karrberg & Liebenau, 2013) because of its many benefits (Stroustrup, 1991; Hill, 2009; conway, 2000; Dubey & Dubey, 2010) to the industry compared to using procedural programming languages. These benefits include software reuse, modularization, programming in teams and maintenance of large systems (Kölling, 1999; Tapscott, 2014). On the other hand, it takes on average 6 to 18 months for a student to shift from procedural to object-oriented (Kölling, 1999; White & Sivitanides, 2005). High dropout rate are found on the first year of a university because of the shifting process from procedural to object oriented programming (Ali & Shubra, 2010). Therefore, many schools and universities are introducing computer programming by using OOP concepts.
As our business model is taking a way with the object-oriented programming rather than the structured programming model (Karrberg & Liebenau, 2013) and as our world is turning into a digital economy, we need to teach people whatever we need in our new industry. Many universities and secondary schools are currently in the process of integrating OOP into their curriculum to meet the job market requirements (clark-Bishop & Kiper, 1998). In this paper, an analysis is done to identify the undergraduate computing courses of both the University of Mauritius and University of Technology Mauritius, introducing OOP as first programming concept in their course structure.

In structured programming, we are more focused with syntax and variables. With object oriented we are more focused with real-life objects. It was seen that problems faced by most of computer programming students are the programming syntax. Students also find it difficult to understand terms such as variable, data type, or memory address which are not really related to real life objects. (Miliszewska & Tan, 2007). Teaching object oriented is difficult because teachers and support material, software tools are still in a state of infancy (Miliszewska & Tan, 2007; Livovský, et al., n.d.).
Many experiments and researches are being done around the world to help and support students to learn OOP. A survey in 2003 was done and it was found that Java is being used in the industry more than other programming languages (Raadt, et al., 2003).The comparison of objects-first and Objects-later was carried out. The research affirmed that both methods have the same learning gain. However, the differences are in the complexity of the topics. Object-oriented programming is seen to be more difficult compared to procedural programming. Meyer and Barbara in their article, emphasized on shifting from procedural to OOP in the curriculum. They proposed a redesign of the teaching and other software topics in universities on an object-first approach (Meyer & Barbara, 1993). Similarly, University of Sydney has emphasized in introducing object oriented classes for its first year computing students (Kölling et al., 1995), the Systems Analysis department of Miami University also opted for this approach (clark-Bishop & Kiper, 1998), the Department of Computer Science at Georgetown University, Washington (United States) encouraged an object first approach for their introductory programming classes (Blake & Cornett, 2002) and last, but not least, St Edwards University in the United States of America (st_Edwards_university, 2014) and Victoria University of wellington, New Zealand (Victoria_university, 2015) have both in their undergraduate bulletin of 2015 an object oriented module in their computing courses.
Methodology
The research consists of two quantitative analysis. The first analysis will allow us to identify Mauritian universities which are introducing Object-Oriented Programming in the first year of their particular undergraduate courses. The second analysis will allow us to identify the number of undergraduate courses teaching Object-Oriented Programming (Either in first year or on any other years of their program) in these two universities (UOM and UTM).
Results
In 2015, we had 8 undergraduate courses teaching computer programming at the University of Mauritius (UOM) and 6 undergraduate courses at the University of Technology of Mauritius teaching computer programming. Some of the programming modules taught were: structured programming, internet programming and object-oriented.
The figure below is a table which consists of computing courses at both UTM and UOM in 2015. The courses taught computer programming module in either year1 or year. This is being shown in the following table. Those modules which are teaching object-oriented are in purple colour. An acronym (A, B, C, D etc.) is used in the table to refer each undergraduate course.

Figure 1 Object oriented module in each course
As we can see 8 undergraduate courses out of 14, have object-oriented in their curriculum. Some of them have introduced it in the first year and others in the second year. 6 of the undergraduate courses, although teaching programming principles are not catering for object oriented.

Figure 2 Number of OOP modules at UOM and UTM
From figure 1 and Figure 2, we can deduce that Object-Oriented Programming (OOP) was still not introduced in the first year of UOM computing courses in 2015. They introduced OOP in the second year for only 3 out of 8 of their courses. On the other hand, UTM has excelled the graph. We can see that on the first year of their computing courses, object-oriented is being introduced in most of their courses.

Conclusion
As discussed, we have 6 known courses which do not have OOP module in their courses. The need to include OOP is important. Corad and French (Conrad & French, 2004) have identified a relationship between Object Oriented techniques and mathematical entities. Abstract mathematical concepts (ring, group, metric space) can be visualized by the concept of abstract classes. They strongly advise to include OOP in mathematics/mathematics and computer science in undergraduate courses to improve student conception. Therefore, both “BSc (Hons) Mathematics with Computer Science” and “BSc (Hons) Mathematics” should consider OOP module as well. Furthermore, courses in electronic should also include OOP in their syllabus because OOP is also seen to be important in the field of physics, chemistry and electronics. One example includes, OOP can help us to better have user interfaces for a better representation of mature density functional theory or molecular dynamics code (BAHN & JACOBSEN, 2002).
We should encourage universities in Mauritius to include object oriented in their IT curriculum as many universities across the world is doing it because we are still in the state of infancy regarding OOP awareness in the country. We should always prepare our new generation for a new digital economy (Karrberg & Liebenau, 2013).

Welche Schlüsselwörter werden in der Zusammenfassung verwendet?
Die Schlüsselwörter sind: Object-Oriented Programming (OOP), Universitäten, Computerprogrammierung, Bachelorstudiengänge und digitale Wirtschaft.
Warum ist objektorientierte Programmierung laut Einleitung wichtig?
Die objektorientierte Methode scheint die Produktivität der Programmierer zu steigern, die Gesamtkosten der Software zu senken und vor allem Software zu erstellen, die die Wiederverwendung fördert und somit leichter zu modifizieren ist. Sie ist in der Industrie weit verbreitet aufgrund von Vorteilen wie Software-Wiederverwendung, Modularisierung, Programmierung in Teams und Wartung großer Systeme.
Welche Herausforderungen werden beim Unterrichten von OOP erwähnt?
Es wird erwähnt, dass es durchschnittlich 6 bis 18 Monate dauert, bis ein Student von prozeduraler auf objektorientierte Programmierung umsteigt, was zu hohen Studienabbruchquoten im ersten Studienjahr führen kann. Schüler haben auch Schwierigkeiten, Begriffe wie Variable, Datentyp oder Speicheradresse zu verstehen, die nicht wirklich mit realen Objekten zusammenhängen.
Welche Methoden werden im Methodikteil beschrieben?
Die Forschung besteht aus zwei quantitativen Analysen: Die erste identifiziert mauritische Universitäten, die OOP im ersten Jahr ihrer Bachelorstudiengänge einführen, und die zweite identifiziert die Anzahl der Bachelorstudiengänge an UOM und UTM, die OOP lehren (entweder im ersten Jahr oder in anderen Jahren).
Was sind die wichtigsten Ergebnisse der Analyse?
Im Jahr 2015 hatten 8 von 14 Bachelorstudiengängen in der Analyse OOP im Lehrplan. UTM führte OOP in den meisten Kursen im ersten Jahr ein, während UOM dies erst im zweiten Jahr für 3 von 8 Kursen tat. 83% der Bachelorstudiengänge an der UTM führten objektorientierte Programmierung ein, verglichen mit 37% an der UOM.
Welche Kurse wurden als solche identifiziert, die kein OOP-Modul haben?
Die folgenden Kurse wurden als solche identifiziert, die kein OOP-Modul haben: BSc (Hons) Mathematics with Computer Science, BSc (Hons) Mathematics and Kurse in Electronic.
Welche Empfehlungen werden im Fazit gegeben?
Es wird empfohlen, OOP in Mathematik- und Informatikkurse aufzunehmen, um das Verständnis der Studenten zu verbessern. Es wird empfohlen, Universitäten in Mauritius zu ermutigen, objektorientierte Programmierung in ihre IT-Lehrpläne aufzunehmen, um die neue Generation auf die digitale Wirtschaft vorzubereiten.
