The City Cloud

The final thesis for our Bachelor project. The City Cloud is an extensible system which allows multiple data sources to be accessed from one endpoint, without having to store intermittent data. It relies strongly on the notion of Open Data and encourages governments and firms to publically share data. This can inspire developers and stimulate...

Copy-Paste Detection in Spreadsheets

When a company is in need of a reporting tool, the most commonly made decision is to choose for Excel. In fact, over 90% of the world’s companies base their decisions on a report made using Excel. This shows that the number of spreadsheet designers, of end-user programmers, is large. It has been estimated to be 5 times as large as the number of...

Infopact Partner Portal

A report on the design, development and implementation of the new Partner Portal used by Infopact, a supplier of DSL infrastructure and services.

Automating Acceptance Tests of a Distributed Application

Designing software tests is oftentimes just as challenging as designing the system under test (SUT) itself. A complex SUT will require a complex test suite to achieve a substantial amount of test coverage, and to install confidence in its correctness. In order to engineer complex systems, software engineers frequently apply patterns that are...

A model driven IDE for M-industries’ Alan

While software is becoming increasingly important in our world, software development is also advancing with an increasing pace. One of the reasons is the increase in available information, which triggered the birth of a new programming paradigm: Model Driven Development (henceforth MDD). Though this can shorten the development time and make it...

Tool-assisted Spreadsheet Refactoring and Parsing Spreadsheet Formulas

Spreadsheets have a life-cycle similar to that of other software: they are inherited throughout an organization, are maintained by different users, and evolve over time to meet changing requirements. This leads to increased complexity and technical debt. In software engineering, refactoring is used to combat these problems by improving software...

Share2pleyapp

Share2Pley is a company that loans LEGO sets on holiday parks to people who are on a holiday. After these sets are returned, the completeness of these sets needs to be checked. Currently, this is done by weighting the returned set. This is not error-prone because each balance scale has a deviation of a few grams. A LEGO brick only weights a few...

Patient Health Network

Ivido is a start-up company that aims at improving the communication and efficiency in health care. To do so, Ivido has developed a platform where health care professionals can create health courses for their patients, to stimulate them to become more involved in their own health care program. Because of lack of means to communicate, the client...

Teaching Computational Thinking - What do our educators need?

In the Netherlands a task-force, supported by the institute of curriculum development, Stichting Leerplan Ontwikkeling (SLO), has been assembled to define core objectives and learning goals for digital literacy that are to be finalized by 2019. The SLO defined digital literacy with the following four elements: ICT basic skills, computational...

Automated timetable generation for Egyptian schools

Cairo-based IT company Key2Soft is working on a comprehensive system to automate various systems in Egyptian primary-,middle- and high schools. This software system, named Key2School, includes a timetabling component, with which the company aims to relieve the workload of timetablers by providing them with a system which automatically generates...

Improving Code Quality in Agile Software Development

Agile software development is a popular approach for developing software. Another important topic of research in software engineering is code quality. Unfortunately, a minimal amount of extensive research has been done on how these two influence each other. The goal of this study is therefore to explore the connection between these two using a...

Self-efficacy of Dutch primary school teachers towards programming education

Only 32% of the Dutch primary schools do something with programming, despite its benefits on students’ skills, job opportunities, understanding of the world, and diversity. Primary school teachers not getting involved with programming education can be caused by a lack of belief in their teaching programming abilities. The belief in your own...

Design of Human Computer Interface for blind children to learn programming languages

As the modern world progressing towards digital technologies, there is an increasing need for school students to learn programming skills so that they fit into the labor market now and in the future. Tangible programming toys and block-based languages are popular among younger children to learn to code. Students in middle and high school in...

Generating Teacher Feedback through Parsons Problems

As computer science lies at the heart of almost all technological progress, widespread computer science education, and particularly programming education, is of great importance. In order to reach a large group of students, secondary schools can play an important role. However, students have difficulty learning programming concepts. Programming...

Investigating the Perception and Effects of Misunderstandings in Java Code

Although writing code seems trivial at times, problems arise when humans misinterpret what source code actually does. One of the potential causes are “atoms of confusion”; the smallest possible patterns of misinterpretable source code. The misunderstandings and errors have been studied in past for the C programming language. They are found to...

The Error that is the Error Message: Comparing information expectations of novice programmers against the information in Python error messages

Learning to program is not a easy task, as has become evident from the abundance of research papers concerning the subject. One of the learning barriers of learning a new programming language is understanding their error message, as coding errors have to be resolved before the programmer can run the code or add new functionality to the program....
