Talvez deva tentar algumas variações de ortografia:
teaching program » teaching proposal (Expandir a busca), teaching process (Expandir a busca)
coder coupling » mode coupling (Expandir a busca), model coupling (Expandir a busca), core coupling (Expandir a busca)
coupling level » coupling model (Expandir a busca)
level teaching » legal teaching (Expandir a busca), efl teaching (Expandir a busca), federal teaching (Expandir a busca)
coder python » codigo python (Expandir a busca), compra python (Expandir a busca)
code python » codigo python (Expandir a busca), pacote python (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( coder python code python programming ) OR ( coder coupling level teaching program ))~.
