'Zurückwerfen' (to throw back/reflect/set back) is a separable verb. The prefix 'zurück-' comes at the end in a main clause, while in a subordinate clause and in the infinitive with 'zu' it remains attached to the verb.
Der Spieler warf den Ball sofort zurück.
The player threw the ball back immediately.
The word consists of the prefix 'zurück-' (back) and the verb 'werfen' (to throw). The literal meaning 'etwas zurückwerfen' (to throw something back) is the basis for all uses, including the figurative ones.
Die Mauer warf den Schall des Rufes zurück.
The wall reflected the sound of the shout.
In the figurative meaning, the structure 'jemanden/etwas um [Zeitspanne] zurückwerfen' (to set someone/something back by [period of time]) is often used. This expresses how large the setback or delay is.
Die Krankheit hat ihn in seiner Ausbildung um ein ganzes Jahr zurückgeworfen.
The illness set him back by a whole year in his training.
In the meaning 'reflektieren' (to reflect), the verb usually refers to physical phenomena. Typical subjects are surfaces such as a mirror, water, or a wall that reflect light, sound, or heat.
Die Felsen warfen ein deutliches Echo zurück.
The rocks reflected a clear echo.

'fördern' and 'zurückwerfen' both describe how something affects development or progress. 'fördern' means that you actively support and move something forward, for example a project, a child, or an idea. 'zurückwerfen' is the opposite: something hinders progress so much that you are back at an earlier stage. So 'fördern' fits when something helps. 'zurückwerfen' fits when something causes harm or delays progress.
