2. In class, the OCDT instructing had a cadet who was talking out of turn stand at attention facing the corner of the room for a portion of the period.
What Blackadder said. As to the pushups, while I've no particular issue on principal with that sort of thing, there was a comprehensive banning of punitive PT a few years back: haven't looked lately, but expect that particular reg's still in force. If it turns out not to be, proceed with caution, if at all: the ban appeared at least partly due to idiots abusing that particular tool.
Will amplify, for general consumption, the comment regarding cadets and treatment as young adults, as this seems to elude some people: they will rise or sink, as a collective, to the expectations and structure they are given.
The LHQ and CTC program "as written" does not necessarily draw the best out of first and second years; certainly, Sea side has significant overlap with the Navy League cadet program (9-12) in the first, and to a certain extent second year programs (i.e., the corps program's designed initial expectations are achievable by ten year olds), so corps must develop and encourage maturity through extracurricular and unit-cultural means. Approaches and processes that require maturity, good judgment, independence, and responsibility within the scope of a first- or second-year cadet's world will pay dividends when those cadets are moving into NCO and instructor roles. In units where this has not been the case, it's a major effort to establish that sort of environment, especially in a corps without strong cadets in senior roles (the Book would say WO-CWO; small corps reality's generally "sharp MCpl" and up).
As to classroom management, better to take a five-minute break, send the rest of the class away for a turn around the building, and have a chat with any particularly disruptive individuals. If that doesn't deliver, consider removal from the class at a convenient time: let them cool their heels, out of sight of their peers and not derailing instruction, in the orderly room or training office.
