Accommodation	Accommodation is achieved when we can do the thinking needed to create a new schema or modify an old schema in order to explain a new experience.
Assimilation	Assimilation is achieved when we can integrate new experiences into existing schemas.
Assumption	Assumption is an idea whose truth can be taken for granted.
Assumption Layers	Assumption layers can appear beneath simple assertions. Such layers consist of multiple hidden and unexamined assumptions influenced in turn by one or more value assumptions beneath the whole.
Counter claim	Counter claim is a response to a claim with a defense or with another claim.
Disequilibrium	The confusion and discomfort felt when a new experience cannot be integrated into existing schemas.
Equilibrium	A stable inner feeling of well being that we feel when our thinking enables us to modify or create a new schema that better explains our world.
Hidden Assumption	A hidden assumption is an unclear and unstated idea assumed to be true that is integral to a line of reasoning. In an argument, it is a hidden premise that cannot be examined for truth and validity. Blind acceptance of a hidden premise can lead to the acceptance of a false or invalid conclusion.
Infer	To use imagination and reasoning to fill in missing facts. To connect the dots.
Lateral thinking	Lateral thinking solves problems by reviewing options, overcoming assumptions, and inventing new solutions. Vertical thinking follows more conventional step-by-step logic.
Principal claim and reasons	These are the two parts of an argument. The principal claim is the thesis or conclusion. The reasons support this claim through evidence or other claims. A claim is an assertion about something.
Schema	Schemas are the mental files in which we store our explanations of experiences.
Thesis	A thesis is a short summary statement of an idea that an essay intends to prove. It is also called the thesis statement and controlling idea.
Thinking	Purposeful mental activity such as reasoning, deciding, judging, believing, supposing, expecting, intending, recalling, remembering, visualizing, imagining, devising, inventing, concentrating, conceiving, considering.
Value or Belief Assumption	Value assumption is a belief that we take for granted, one that rarely questioned or even articulated. Remaining hidden and unexpressed, a value assumption can nevertheless shape a chain of reasoning.
Working Assumption	A working assumption is a trial idea, theory, strategy, or hypothesis assumed to be true in order to further an investigation. It is a conscious assumption.
