The basis for conceptualizing the technology of food dehydration process’ inclusion in the high school curriculum and in the vocational course offering is to provide an option window for secondary level students to acquire skills and knowledge aside from the basics taught in the other subjects that can lead to a path to entrepreneurship and income generation. Prior to the revision of the basic secondary curriculum, the focus was preparing students for higher education less in knowledge base which required critical thinking skills rather than occupational learning.

The main idea of each paragraph should be stated in a topic sentence. The topic sentence should appear as the first sentence in each paragraph. It directly supports your thesis statement, developing the ideas previewed in the introductory paragraph. It acts as a guidepost for your readers, making it easy to follow your discussion. Each detail in the paragraph should work to support or develop this topic sentence. Any details that do not support topic sentences should be revised, moved, or deleted.

A * formal system* (also called a * logical calculus* , or a * logical system* ) consists of a formal language together with a deductive apparatus (also called a * deductive system* ). The deductive apparatus may consist of a set of transformation rules , which may be interpreted as valid rules of inference, or a set of axioms , or have both. A formal system is used to derive one expression from one or more other expressions. Although a formal language can be identified with its formulas, a formal system cannot be likewise identified by its theorems. Two formal systems
F
S
{\displaystyle {\mathcal {FS}}}
and
F
S
′
{\displaystyle {\mathcal {FS'}}}
may have all the same theorems and yet differ in some significant proof-theoretic way (a formula A may be a syntactic consequence of a formula B in one but not another for instance).
