How did Wassily Kandinsky’s art change after the Bauhaus moved to Dessau?

When the Bauhaus school moved from Weimar to Dessau in 1925, Wassily Kandinsky’s role at the institution shifted significantly. Prior to the move, his teaching duties were largely focused on applied arts, such as directing the mural workshop and lecturing on color and form. Following the relocation to Dessau, he was finally able to lead a class in "free," nonapplied painting.1

During this period, Kandinsky continued to evolve toward geometric abstraction. His work maintained a sense of dynamism and a preference for detail-crowded pictorial space, which echoed the sweeping-gesture techniques of his earlier career. His artistic theory also matured during these years; in 1926, he published his second major treatise, Punkt und Linie zu Fläche ("Point and Line to Plane"). In this work, he applied the same analytical spirit he had previously used for color to the abstract elements of drawing, interpreting lines through their supposed psychological effects—for instance, characterizing horizontal lines as cold and vertical lines as hot.1
