STAAR Not Aligned with TEKS

Print Friendly

The science STAAR tests do not align with the science TEKS.

One of the TEKS Science Process Skills that is emphasized is for students to repeat trials when investigating. Following is the TEKS used for every grade level. Students are taught that one trial is not enough information to make a conclusion. Yet, the TEA test writing group includes test questions such as the one below that does not align with this process skill.

(D)  construct tables and graphs, using repeated trials and means, to organize data and identify patterns; and……

Some of the science STAAR questions are incorrect and some like the one shown below do not align with the science process TEKS.

Let me repeat:
The science process TEKS for each grade level is:
(D)  construct tables and graphs, using repeated trials and means, to organize data and identify patterns; and
One major process is to repeat an investigation and take the average (the mean). Notice that the STAAR question specifically states that the car rolls down once for each type of surface. TEA test writers do not understand the scientific method. The TEKS for this question is given as 8.2E The problem is the 8.2E is not an independent science process skill. Instead, it depends on the previous process skills, especially 8.2D, which specifies that repeated trials are required.
TEA claims that the STAAR contains rigorous question, but it appears the writers are not familiar with the science TEKS the test questions are suppose to be aligned with.
(D) construct tables and graphs, using repeated trials and means, to
organize data and identify patterns; and
(E) analyze data to formulate reasonable explanations, communicate
valid conclusions supported by the data, and predict trends.
