Sometimes Scholar can feel like its healing potency from its spells is low and this is true to some extent since half your heals create shields for most of their effective value. Don't forget you can pump up your numbers with Largesse, Fey Illumination, and Dissipation. Fey Illumination is really interesting because all healing spells benefit from this buff on the party meaning you increase your cohealers output too. If you don't have Indomitability in an instance your biggest contribution as a healer is pre emptive shields but after you gain Indomitability you will have to judge whether shielding at a huge cost of MP is necessary when you can refill the entire groups health for free with Indom. Your cool downs are low with Scholar so try to rely on Aether Skills except Sacred Soil. Its not useful much outside Savage Content or Signature Boss Attacks and can waste valuable healing skills.
