Recent accessibility drives and price wars between the major South African (SA) cell phone companies suggest that the landscape for the adoption of mobile learning (m-learning) at the Higher Education Institution (HEI) level may be changing. As such, there is a need to gauge the current mobile readiness of students for m-learning. Mobile technology readiness refers to the extent to which students have access to mobile devices (not only handsets), and can afford data bundles that meet or exceed the requirements of a base set of currently available m-learning applications (Naicker and Van der Merwe 2012). Mobile operational readiness refers to students’ awareness of, attitude towards, support and training that is required for m-learning. This study conducted an assessment of the technology and operational readiness of students at a SA HEI. An in-depth literature survey was undertaken to delineate technology and operational readiness of students for m-learning. For technology readiness, an investigation was conducted on m- learning applications that are currently available and the technology requirements of these mobile applications. This was undertaken to determine the extent that the current student mobile handset profile match these requirements. The literature review also included a search for mobile opeeratratiioonnaall ffaactorctorss ssuuchch aass ssttuuddeennttss’’ aawwaarenerenessss ooff aanndd aattttiittuuddee ttoowwaarrddss mm--lleaearrnininngg as well as m-learning support and training that students require. The philosophical underpinning of this study was based on Activity Theory. The strategy of inquiry employed was a case study approach. Data was collected from students at the Durban University of Technology, a resident based SA HEI. A mixed methods data collection strategy was employed. The researcher used a field survey questionnaire as the primary research instrument to assess mobile technology and operational readiness. Focus group interviews were used as a secondary data gathering tool to triangulate and strengthen the results. The results were presented using descriptive and inferential statistics and were analyzed using the lens of activity theory. In terms of technology readiness, despite a high level of ownership and reasonable compliance with application requirements, data costs remain prohibitive. In assessing operational readiness, despite a positive attitude, the majority of the students require awareness, ongoing support and training. Several recommendations based on the findings are offered. For example, one of the findings showed that mobile connectivity affordability was low amongst students and it is recommended that the HEI work around exorbitant connectivity costs by combining m-learning technologies to form meaningful m-learning approaches at a minimum cost. Another finding showed low awareness of m-learning at the HEI. A recommendation advanced to combat this finding is for the HEI to encourage and support dialogue among key stakeholders. This study concludes that any m-learning endeavour to implement m-learning at this HEI is bound to fail as only a small percentage of students are aware of m-learning and can afford data bundles to implement m-learning in its true sense. As an implication of this study to other HEI’s, the researcher suggests that regular mobile readiness surveys be conducted. / Science and Technology Education / M. Sc. (Information Systems)

Diese kumulative Dissertation untersucht die Rolle mobiler Geräte im Informationsverhalten junger Kinder aus verschiedenen Perspektiven. Einerseits wird erforscht, ob informationsbezogene Aktivitäten Teil der Nutzung mobiler Technologien durch junge Kinder sind. Andererseits wird untersucht, ob Aspekte des kindlichen Informationsverhaltens bei der Sichtweise von Eltern und Kinder auf die Nutzung von mobilen Geräten eine Rolle spielen. Die erste in dieser Arbeit vorgestellte Studie bietet einen explorativen Einblick in die Nutzung mobiler Geräte durch junge Kinder anhand von Interviews mit Eltern von Kindern im Alter von ein bis sechs Jahren. Basierend auf einer Sekundäranalyse der Interviewdaten wird im Rahmen der zweiten Studie erforscht, wie Eltern die Nutzung von Mobilgeräten durch ihre Kinder wahrnehmen und medienpädagogisch begleiten und diskutiert, wie dies das Informationsverhalten der Kinder beeinflussen könnte. Unter Anwendung eines Uses-and-Gratifications-Ansatzes wird in der dritten Studie untersucht, was Kundenrezensionen für ein Kinder-Tablet über die Nutzung des Geräts und die Erwartungen von Familien aussagen. In der vierten Studie wird anhand eines multimethodischen Ansatzes ein besonderer Fokus auf die Einbeziehung der kindlichen Perspektive gelegt und erforscht, wie Kinder im Alter von vier bis sechs Jahren mobile Geräte nutzen und ob Aspekte des kindlichen Informationsverhaltens eine Rolle bei der Sichtweise von Familien auf die Nutzung spielen. Insgesamt zeigen die Ergebnisse, dass mobile Geräte definitiv eine Rolle im Informationsverhalten von jungen Kindern einnehmen können, wobei ihr Potenzial für die Entdeckung von Informationen oftmals nicht im Vordergrund der Wahrnehmung durch Eltern und Kinder steht. Mit diesen Erkenntnissen leistet die Arbeit einen wichtigen Beitrag zur Adressierung bestehender Forschungslücken im Bereich des Informationsverhaltens junger Kinder im Allgemeinen sowie im spezifischen Kontext der Nutzung mobiler Geräte. / This cumulative doctoral thesis examines the role of mobile devices in young children's information behavior from different perspectives. On the one hand, it explores whether information-related activities are part of young children's use of mobile technologies. On the other hand, it investigates whether aspects of children's information behavior play a role in parents' and children's perceptions of mobile device use. The first study presented in this thesis gains exploratory insight into young children's use of mobile devices through interviews with parents of families with children aged one to six years. Based on a secondary analysis of the interview data, the second study examines how parents perceive and mediate young children's use of mobile devices and discusses how this might influence children's information behavior. By applying a uses and gratifications approach, the third study investigates what customer reviews for a tablet for children reveal about the use of this device and expectations of the families. Using a multi-method approach, the fourth study places a particular focus on the inclusion of children's perspectives and investigates how children aged four to six years use mobile devices and whether aspects related to children's information behavior play a role in families' perceptions of this use. Overall, the results show that mobile devices can clearly play a role in young children's information behavior, although their potential for children's information discovery is not always prominent in parents' and children's perceptions. With these findings, this work makes an important contribution to addressing existing research gaps regarding young children's information behavior in general as well as in the specific context of mobile device use.

At the beginning, the work describes DNS and SSL/TLS protocols, it mainly deals with communication between devices using these protocols. Then we'll talk about data preprocessing and data cleaning. Furthermore, the thesis deals with basic data mining techniques such as data classification, association rules, information retrieval, regression analysis and cluster analysis. The next chapter we can read something about how to identify mobile devices on the network. We will evaluate data sets that contain collected data from communication between the above mentioned protocols, which will be used in the practical part. After that, we finally get to the design of a system for analyzing network communication data. We will describe the libraries, which we used and the entire system implementation. We will perform a large number of experiments, which we will finally evaluate.
