Abstract: Some embodiments provide narrative feedback generator that assists a user in composing narrative feedback paragraphs. In one embodiment, a method stores sentences associated with a plurality of performance levels and with one of a plurality of feedback element tiers and links sentences between different tiers. The method also receives a selection of an output document type and an individual of the output document. The method then filters for a first set of sentences associated with a first tier in the hierarchy and presents the first set of sentences to the user and receives a selection of a first sentence in the first set of sentences. Additionally, the method filters for a second set of sentences that are associated both with a second tier in the hierarchy and linked to the first sentence and presenting the second set of sentences to the user and receives a selection of a second sentence in the second set of sentences. The method then generates a paragraph comprising the first and second sentences.

Abstract: A device for attachment to a chute of a ball pitching machine includes a ball feeder tube having a first end for receiving a first ball. A retaining member is fixed relative to the ball feeder tube and extends transversely to the ball feeder tube into the bore for selectively retaining the first ball in the bore. The retaining member is resiliently deformable toward the ball feeder tube for allowing the first ball to move past the retaining member toward the chute upon application of a predetermined force on the first ball. The ball feeder tube defines a bore having a diameter. The retaining member is spaced along the bore a first distance from the first end. The first distance is shorter than the diameter of the bore so that insertion of a second ball into the first end with the predetermined force displaces the first ball toward the chute.
