Profile Results
Below is a web example demonstrating a prototype layout that may be employed by the automated online rubric/profile tool. The examples below depict how the results might look using histograms should multiple users (trained in the application of the rubric) aggregate their responses when evaluating a single instructional material. At the bottom of
this page is an graphic example of
how the alignment results might look when comparing alignment across
multiple sites. NOTE: The profile below is still in reversionary stages for layout and content. This is a static profile and is not based off the online rubric section B.

PROFILE RESULTSDescriptor: B1a. Material provides an opportunity to learn how different kinds of questions based on prior scientific knowledge suggests different kinds of investigations. |

Data Table: Seven evaluators selected the following choices: 1, 2, 2, 2, 3, 2, 3 Mean = 2.1 Median = 3.0 Mode = 2 Std. Dev = .69 N = 7 |
An interpretation of histogram B1a is also available. Just close the pop-up window when finished reviewing the window contents. |

Caution: It may be helpful to reiterate that sites varying by several tenths in alignment are not significantly different from one another with respect to the NLIST rubric. The numeric values displayed when comparing several web sites within a specific section of the rubric section will actually be displaying the "average" degree of alignment as determined by multiple, trained and proficient users of the rubric. The profiles are generating overall averages of alignment and not holistic summative point values or individual frequency distributions. Finally, it would seem erroneous to compare an entire web like NASA CONNECT to an individual activity like AAAS Peanut. This would be comparing apples to oranges. It would also seem difficult to compare one large site like GLOBE to another large site like CONNECT because of the enormous amount of information contained in each web. The difficulty in comparing large web sites lies in defining/classifying which portion of each web the rubric is being aligned with. Our rubric at this point in its development appears more geared toward aligning one specific learning experience against another versus evaluating one large web site against another large web site. This is an issue that will need to be addressed by NLIST and future users of the instructional materials rubric. |
