All of the items on the teacher assessments target understanding of science content in one of three different ways:<\/p>\n

    \n
  1. Knowledge of science content (Level 1 items);<\/li>\n
  2. Using content knowledge to analyze\/diagnose student thinking (Level 2 items); and<\/li>\n
  3. Using content knowledge to make instructional decisions (Level 3 items).<\/li>\n<\/ol>\n

    Knowledge of science content<\/h3>\n

    All of the ATLAST items for teachers assess knowledge of science content, but the most basic type of question attempts to isolate disciplinary content knowledge from a teachers\u2019 ability to apply the knowledge in making instructional decisions. An example of these “Level 1” items is shown below (correct answer is C).<\/p>\n

    \"\"<\/p>\n

    Although the item is set in an instructional context, it does not ask the teacher to apply knowledge of science content.<\/p>\n

    Using science content knowledge to analyze\/diagnose student thinking<\/h3>\n

    “Level 2” items require teachers to apply<\/em> their content knowledge in analyzing or diagnosing a sample of student thinking.\u00a0 An illustrative item is shown below (correct answer is D).\"\"<\/p>\n

    A teacher must understand the science content in order to answer Level 2 items correctly.\u00a0 However, additional analysis of the question is required because more than one of the choices includes a correct science statement, unlike the Level 1 item above. In the Level 2 item shown here, the statements in choices A, B, C and\u00a0D are correct in terms of the science, but only\u00a0D also<\/em> applies to what the students said.\u00a0 This feature is present in all Level 2 items and makes the cognitive load of these items higher than that of Level 1; teachers must evaluate the students\u2019 thinking in relation to the physical scenario in order to choose the correct answer.<\/p>\n

    Using content knowledge to make instructional decisions<\/h3>\n

    “Level 3” items ask teachers to apply their content knowledge in choosing among instructional moves. A sample Level 3 item is shown below (correct answer is C).\"\"<\/p>\n

    Level 3 items have the highest cognitive load; teachers must evaluate the physical scenario, the student\u2019s thinking in relation to the physical scenario, and then evaluate each instructional choice.\u00a0 As with Level 2 items, more than one answer choice has a correct science statement, but only one has a correct science statement and<\/em> is relevant to the instructional context. Although the cognitive load of Level 3 items is demanding, it is a small fraction of the demand placed on a teacher managing the learning of a classroom of students.<\/p>\n","protected":false},"excerpt":{"rendered":"
