Writing a book, painting pictures or other creative challenges are much harder. And yet many fail at comparable competences. Teaching programming skills by listening and reading is not enough. Students need the process of trial and error in order to acquire the skills needed and should be able to learn by them. However, students should be able to work independently on a computer. The problem that the beginners are overwhelmed and the advanced are bored. This is the case especially in computer science. Despite the use of a comfortable Learning Management System (LMS), many tasks have been submitted to paper and PDF at our university so far. Since the available question-types could not cover all possible complex tasks, it was difficult to inspire the lecturers for a complete digitization of their tasks. To be able to automatically evaluate even tasks in mathematics, computer science and related scientific disciplines two modules have been successfully evaluated at our university. This paper presents the use of these Moodle modules STACK and VPL in selected courses in mathematics and computer science and how to randomize tasks. In these modules complex tasks are prepared in such a way that they are still solvable for the students and automatically evaluated by the system, thus could considerably facilitate the work of the lecturers and academic staff.

Since there is currently no well-functioning option for this, we decided to develop an extension for integration into our question exchange platform. For this purpose, a new Moodle plugin was developed at BTU Cottbus - Senftenberg that converts questions from the QTI 2.1 standard into Moodle XML and vice versa. The aim was to convert as many question types as possible free of loss.

The main objective of this paper is to present a robust writer verification system by using cursive texts as well as block letter words. To evaluate the system, two datasets have been used. One of them is called Secure Password DB 150, which is composed of 150 users with 18 samples of single character words per user. Another dataset is public and called IAM online handwriting database, and it is composed of 220 users of cursive text samples. Each sample has been defined by a set of features, composed of 67 geometrical, statistical, and temporal features. In order to get more discriminative information, two feature reduction methods have been applied, Fisher Score and Info Gain Attribute Evaluation. Finally, the classification system has been implemented by hold-out cross validation and k-folds cross validation strategies for three different classifiers, K-NN, Na{\"i}ve Bayes and Bayes Net classifiers. Besides, it has been applied for verification and identification approaches. The best results of 95.38\% correct classification are achieved by using the k-nearest neighbor classifier for single character DB. A feature reduction by Info Gain Attribute Evaluation improves the results for Na{\"i}ve Bayes Classifier to 98.34\% for IAM online handwriting DB.

The work packages include the development of online subject quizzes(online self-assessments), in order to support prospective students to compare their individual knowledge levels with the knowledge required at the beginning of their studies. Depending on the results achieved, e-learning units are provided with the necessary subject-related knowledge.These unitscan be refreshed independently and the attendance of preliminary courses is recommended. The basis for the online assessments is a cross-university question exchange platform on which the affiliated universities sharethe developed questions and thereby establish a nationwide quality standard for self-assessments. The project partners at Brandenburg University of TechnologyCottbus -Senftenberg (BTU)are responsible fordeveloping the question exchange platform and for making the platform available to all partner universities. For this purpose, a concept was developed, whereinMoodle Learning Management Systems (LMS)is used as a basis and expandedto include functions for storing questions with associated metadata and search functions to search for questions with specific metadata. The concept of the cross-university question exchange platform is presented in this paper.}, language = {en} } @misc{KutznerKostovaBotheetal., author = {Kutzner, Tobias and Kostova, Eleonora and Bothe, Jacqueline and Freytag, Andreas}, title = {Portal for generating cross university didactic self-assessment apps without programming skills}, series = {VIII Jornadas Iberoamericanas de Innovaci{\´o}n Educativa en el {\´A}mbito de las TIC y las TAC (InnoEducaTIC 2021)}, journal = {VIII Jornadas Iberoamericanas de Innovaci{\´o}n Educativa en el {\´A}mbito de las TIC y las TAC (InnoEducaTIC 2021)}, isbn = {978-84-09-35708-6}, pages = {149 -- 156}, abstract = {Based on the didactic concept of a school mathematics app, a portal for the automatic creation of interdisciplinary learning apps without programming knowledge is being developed at the Brandenburg University of Technology Cottbus - Senftenberg (BTU).
