Lehrveranstaltungen im Sommersemester 2018

Seminar zur Begriffsanalyse

Literatur: Formale Begriffsanalyse: Mathematische Grundlagen (Formal Concept Analysis: Mathematical Foundations), B. Ganter und R. Wille, Springer Verlag

 

Mathematik II für Informatiker
Die Klausur wird am 17. Juli 2018 in dem zeitlichen und örtlichen Rahmen der Vorlesung geschrieben. Der zweite Prüfungstermin ist der 25.09.2018. Eine Zulassung zu der Klausur (Modulprüfung) wird genau dann ausgesprochen, wenn Sie 75 Punkte oder mehr bei den Übungsaufgaben erreicht haben. Es gibt genau 12 Übungsblätter, welche jeweils mit genau 10 Punkten bewertet werden.  Die Übungsblätter sind von den Studierenden einzeln (nicht in Gruppen) handgeschrieben jeweils am Tag der Vorlesung vor der Vorlesung abzugeben. Computerausdrucke sind leider nicht zulässig. Eine spätere Abgabe (aus welchen Gründen auch immer) kann leider auch nicht akzeptiert werden.
Am 22. Mai wird ein Zwischentest geschrieben. Dieser wird mit 20 Punkten bewertet. Falls Sie mehr als 10 Punkte im Zwischentest erreicht haben werden,  geht die gesamte Punktzahl in die zu erreichende Punktzahl zur Prüfungszulassung ein, vorausgesetzt,  Sie wählen den ersten Prüfungstermin. Falls sie weniger als 11 Punkte erreicht haben, ist eine Anrechnung dieser Punktzahl für die Prüfungszulassung nicht möglich.
In den Übungen werden ausschließlich die aktuell abzugebenden Übungsaufgaben besprochen. Sie können die Übungsgruppe jederzeit wechseln und an mehreren Übungen teilnehmen. Das Tutorium von Frau Dr. Elke Rosenberger ist der Nachbereitung der Übungsaufgaben vorbehalten. Hier können auch spezielle Fragen geklärt werden. Fragen, welche die Bewertung von Übungsaufgaben betreffen, werden ausschließlich in diesem Tutorium behandelt.
