  1. IBL WS2ibl and concept development Programme Concepts and definitions Representations Always, sometimes or never true

  2. concept descriptive: Definition; critical and variable properties; lower, equal and higher order. Examples and non-examples

  3. Conceptanalysis for Element MACROSCOPIC. An element is a pure substance that cannot be separated into simpler macroscopic substances with characteristic properties that differ from the original substance. MICROSCOPIC. An element is a substance composed of a single kind of atom.

  4. Concept Attributes CRITICAL ATTRIBUTES Cl. It is a kind of matter. (macroscopic) C2. It is pure. (macroscopic) C3. Separation into parts of macroscopic size results in no change in characteristicproperties.(macroscopic) C4. It is composed of a single kind of atom. (microscopic) VARIABLE ATTRIBUTES Vl. It may exist as solid, liquid, or gas. (macroscopic) V2. Examples may have different properties. (macroscopic) V3. It may react easily or with reluctance (macroscopic) V4. Atoms may exist in various size aggregates. (rnicroscopic)

  5. Comparation of concept SUPRAORDINATE CONCEPT: Matter COORDINATE CONCEPT: Compound SUBORDINATE CONCEPTS: hydrogen, oxygen, mercury, iron, copper, helium, naturally occurring element; ,artificial element EXAMPLES: (None withperceptibleattributes) hydrogen, oxygen, sulfur, iron, helium NONEXAMPLES: (None withperceptibleattributes) water, carbon dioxide, hydrogen, sulfide, iron oxide

  6. Graphical representations:of concepts 3. Wordweb • Associative • Cognitiveàndaffective • Oriëntation 1. Conceptmap • Cognitive • Map relations betweenconcepts 2. Mindmap • Associative • Cognitive • Familiarizewithandevoke prior knowledge
