Lehre: Roland Wagner

Sommersemester 2018

Übungen aus Mathematik II

Übungen zu Partielle Differentialgleichungen

 

Wintersemester 2018/19

Übungen zu Analysis 1

Übungen zu Mathematische Methoden in der Kontinuumsmechanik

 

Übungen zu Mathematische Methoden in der Kontinuumsmechanik

Es gibt 13 Übungsblätter zu je 6 Aufgaben. Diese können über die KUSSS-Seite des Kurses geladen werden.

Üblicherweise herrscht bei den Übungen Anwesenheitspflicht. Im Verhinderungsfall kann bis zu zweimal schriftlich abgegeben werden. Abgegebene Übungen müssen jeweils bis Beginn der Übung beim Übungsleiter eintreffen.

Bei jeder Übung werden die schriftlichen Unterlagen zu den gelösten Aufgaben von ein paar Studierenden zufällig gesammelt, um den korrekten Lösungsweg zu überprüfen.

In die Endbenotung fließen die Anzahl der gekreuzten Übungen sowie die Tafelleistung mit jeweils 50% ein. Zu der Tafelleistung zählen auch die beurteilten Übungen der schriftlich abgegebenen Übungsblätter.

Zum Bestehen der Übungen sind sowohl 50% der Übungen als auch 50% der maximal möglichen Tafelleistung notwendig.

Die Endpunktezahl wird also wie folgt berechnet: p:=u*50/umax+t

u: Anzahl der gekreuzten Übungen (≤ umax)
t: Tafelleistung (≤ 50)

Endbeurteilung:

87 p 100: Note 1
75 p < 87: Note 2
62 p < 75: Note 3
50 p < 62: Note 4
    p < 50: Note 5
