thesis
A scientific claim or guiding statement that serves as the starting point for an argument or an academic work and must be proven.
In seiner Masterarbeit muss er eine klare These formulieren und diese mit Daten untermauern.
In his master's thesis, he has to formulate a clear thesis and support it with data.
claim
A pointed, often provocative claim that is put forward in order to stimulate discussion.

The guest speaker began his talk with the bold claim that social media endangers democracy.
'These' is often combined with certain verbs. You can say 'eine These aufstellen' (to put forward/formulate a thesis), 'eine These vertreten' (to support/defend a thesis), 'eine These beweisen' (to prove a thesis), or 'eine These widerlegen' (to disprove a thesis).
Der Wissenschaftler stellte die These auf, dass der Klimawandel die Hauptursache sei.
The scientist put forward the thesis that climate change was the main cause.
The word 'These' belongs to educated and academic language. It is used in academic, intellectual, or formal discussions, but rarely in everyday conversation.
Die zentrale These des Buches ist schwer zu widerlegen.
The central thesis of the book is difficult to disprove.
'These' is part of a word family of Greek origin. Related terms are 'Antithese' (antithesis/opposite) and 'Synthese' (synthesis, the bringing together of thesis and antithesis). 'Hypothese' (hypothesis, an unproven assumption) is also closely related.
Der Vortrag war nach dem Prinzip „These, Antithese, Synthese“ aufgebaut.
The lecture was structured according to the principle of 'thesis, antithesis, synthesis'.
theory
Both words belong to scientific explanations and may not yet be definitively established. These is a single claim or guiding principle that is to be supported and tested. Theorie, by contrast, combines several statements into a more comprehensive explanatory system. Use These for the individual idea and Theorie for the overall model.
Die These der Forscher lautet, dass kurze Pausen die Konzentration verbessern.
The researchers' thesis is that short breaks improve concentration.
