  40. assessment
    process of gathering information about student leaning for decision making
  41. diagnostic
    using assessment before teaching students to decide what specific experiences will best encourage student's learning progress
  42. formative
    collecting data on student learning during a lesson
  43. summative
    assessments taht come after instruction
  44. informal
    involves teachers asking students questions, listening to what they say watching what they do in learning performance and examining the products from their performance
  45. traditional
    assessment typically use multiple choice, true-false, short and essay items
  46. performance
    • assessments are typically sent in authentic contexts and often have the look and feel of regular hands-on learning situation.
    • data tables, graphs, models, reports, written explanations,science projects, and problem solutions
  47. evaluation
    involves using assessment data in judging student performance and making decisions about learning and instruction
  48. What are the science standards
    national science education standards and the standards of the various states define goals that should be achieved in science at different grade levels
  49. where are students now
    a strong knowledge base is important bt emphasis must also be placed on students understanding applying conceptsm and principles, as well as on their being able to use a variety of science processess and investigative procedures
  50. how are students going to get there
    the purpose of classroom assessment is to improve learning and instructions, in light of standards and lesson objectives
  51. 5 main attitudes, values, and habits of mind are especially relevant to successful inquiry in elementary and middle school classrooms
