iRubric: Performance Task (STEM Lab) Write-up & Presentation Rubric

o Formulates a focused problem/research question and identifies the relevant dependent and independent variables (IV, DV, CV)

o Designs and implements a method for the effective control of additional variables that influence results

o Develops and implements a method that allows for the collection of sufficient relevant data

o Appropriate materials and equipment have been chosen, and clearly communicated in the report, to carry out the methods developed

o Formulates a problem/research question that is incomplete or identifies only some relevant variables

o Designs a method that makes some attempt to control the variables

o Develops a method that results in the collection of insufficient relevant data

o Use of appropriate materials is evident in the methods, but those materials were not explicitly communicated

o Does not identify a problem/research question and does not clearly identify the relevant variables

o Designs a method that does not control the variables

o Develops a method that does not allow for any relevant data to be collected

o Inappropriate materials were chosen to carry out the investigation and/or materials are not communicated in the report

o Does not present a purpose of the activity or use the appropriate terms to show that variables are involved

o Fails to develop a method

o Unable to outline equipment and materials required for the investigation

o States a relevant conclusion, with justification, based on a reasonable interpretation of the data

o Compares results and whenever appropriate, calculates Relative error (% error)

o Specific sources of error are identified with analysis of the effect of those errors on the magnitude of results identified

o Suggests realistic, meaningful improvements to experimental methods in respect of identified errors and limitations

o States a conclusion that reasonably reflects the data, but fails to relate how the processed supports this conclusion.

o Identifies some relevant sources of error and limitations, but the evaluation is weak or missing

o Suggests only superficial improvements

o States no conclusion or the conclusion is based on an unreasonable/incorrect interpretation of the data

o Identifies irrelevant sources of error and limitations

o Suggests unrealistic improvements or no improvements

o Conclusion drawn is completing misleading or does not relate to the data in the experiment

o Does not make an attempt to identify any sources of errors

o Does not make an attempt to suggest any improvement to the process

o Presents ideas clearly and in a well-structured manner

o The report facilitates a ready understanding of the focus, process, and outcomes

o Ideas are expressed following a thought pattern that is comprehensible

o The report largely allows for a ready understanding of the ideas expressed together with outcomes

o Ideas expressed are somewhat random and do not reflect a well thought out pattern that is fully comprehensible

o The report allows for
some understanding of ideas expressed

o Ideas are expressed are completely random and do not reflect any thought pattern that is comprehensible

o The report does not allow for a ready understanding of the ideas expressed or the outcomes
