Module Assessment/Evaluation Techniques

"Assessment is a critical issue in an inquiry-based classroom.  It is important that the teacher investigate various assessment techniques that can be used instead of or in addition to traditional techniques. " Edna Gentry, University of Alabama Huntsville.

One of the best ways to assess students is with Sunburst's Learner Profile for the computer and Learner Profile to Go for the PDA.  Teachers can evaluate students on the fly with the PDA with inputed observeables (see standards), load the material from the PDA to the computer and get a print out of each student and their mastery of skills and concepts.

 The following is a partial list of assessment strategies that can be used for this module:
 

  • Students will brainstorm where water can be found (it should include rivers, lakes, oceans, animals, plants, clouds, soil, groundwater, and glaciers),  how groundwater is used, how groundwater is wasted, etc. assessment= participation;
  • Each team will assemble a list of different types of soil with a description of how water permeates each type of soil.  This information can be found by researching journals, assessment=list and descriptions;
  • Teams perform the soil type experiment to determine the rate of absorption of the soil in the well areas, assessment=lab report of experiment;
  • Develop a master list of local occurrences of  how water is wasted and  how students might conserve water better;
  • Students individually keep a journal of the Ogallala Aquifer Water Depletion problem with ideas as the problem progresses, assessment = read journal;
  • Teams develop the computational model (with graphs) of the Ogallala Aquifer Water Depletion and present their findings to the class in an oral presentation, assessment= presentation;
  • Students will individually determine the next course of action after investigating and discussing social implications involved with the conservation of water..
