When the calcium level in the blood is too high, the cells of the parathyroids make less parathyroid hormone (or stop making it altogether), thereby allowing calcium levels to decrease. This feed-back mechanism runs constantly, thereby maintaining calcium (and parathyroid hormone) in a very narrow normal range.
Best Answer: The learning outcome is the thing that the children produce in the lesson, while the learning objective is what you want the children to learn. For example, the learning objective might be: To be able to write descriptively, while the learning outcome could be a story or diary entry etc.
Grade-level learning objectives describe what students should achieve academically by the end of a particular grade level or grade span (terms such as grade-level indicators or grade-level benchmarks may be used in reference to these learning objectives or standards). Course or program objectives: Teachers may also determine learning objectives for courses or other academic programs, such as summer-school sessions or vacation-break programs. In this case, the objectives may be the same academic goals described in learning standards (in the case of a full-year course, for example), or they may describe interim goals (for courses that are shorter in duration).
