The Pros Of Construct Validity

For an assessment to have validity that indicates that the assessment accurately measures what is intended to measure (Frisbie, 2005). For example, if a scientist measures 30 grams of sugar on a scale and the scale shows that the sugar weighs 21 grams, then the scale did not provide an accurate measurement of what was claimed to be the measurement. This is quite similar to an assessment validity because if an assessment intends to measure something in particular, but ends up measuring something that is completely unrelated, then the assessment is not valid (Frisbie, 2005).

Content, criterion and construct validity are the three types of validity that should be considered when determining the validity of an assessment (Frisbie, 2005). Say

For example, in the cell analogy poster presentation, a performance assessment will be used to assess student’s performance. It is important to acknowledge how student’s emotions about science can have an impact on how well they present their cell analogy poster. Students who already lack confidence about their abilities in the area they're being tested on or even students who have anxiety with speaking in front of the whole class can have a hard time articulating their knowledge and comprehension of the topic to the class (Frisbie,

There also needs to be evidence that the test does not measure irrelevant aspects (Frisbie, 2005), such as the pace of their presentation, whether they were confident throughout, and whether it was noticeable that students were nervous.

In a classroom, the validity of the cell analogy presentation assessment can be proven in several ways. For example, high scores on the performance assessment will validate that the intended learning outcomes have been met. In other words, students have mastered their objectives and high percentages will indicate that their learning and mastering the intended contents. In addition, I can also prove the validity of my assessment by having another teacher look at my assessment and compare it to the intended learning
