The above is clearly inappropriate for assessing how much students have learned in chemistry regarding solutions and concentrations. The project described touches so many topics outside of Grade 7 solution chemistry. The criteria are really tangential to concepts such as molarity, molality, percent composition, and solubility. This is not an assessment in chemistry. This is supposed to be the "highest level" yet it fails miserably in measuring how much a student learns in a chemistry class.
There are good assessments and there are bad assessments. And most of the time, it really depends on who wrote the assessment. Some are brilliant while some are simply stupid. Standardized exams are assessment tools as well and these are not necessarily stupid. PISA is one example of a good standardized exam (this is discussed in a previous post on this blog). It is in a "multiple-choice" format and below is a sample question:
The quality of assessments largely depends on how these are constructed. There are excellent "multiple choice" exams and of course, there are poor "performance tasks" (DepEd's sample above is one). Coming from DepEd means a lot of teachers are getting misinformed, which of course leads to poor learning outcomes in schools in the Philippines.
