Dexedrine is made up of 1 amphetamine salt which is dextroamphetamine. Adderall is made up of 4 amphetamine salts, 1 of which is dextroamphetamine which makes up 25% of the Adderall pill. Ritalin usually requires a dosage similar to Adderall and twice that of Dexedrine to be effective. Difference in effect: Adderall is prescribed in approximately twice the dosage of Dexedrine. A 10mg pill of Adderall contains 2.5mg of Dexedrine but has similar effect as 5mg of Dexedrine. Due to the 4 different salts and increased dosage needed, Adderall is more likely to give side effects than Dexedrine.
Norm-Referenced Assessment: A test or other type of assessment designed to provide a measure of performance that is interpretable in terms of an individual's relative standing in some known group. Criterion-Referenced Assessment: A test or other type of assessment designed to provide a measure of performance that is interpretable in terms of a clearly defined and delimited domain of learning tasks.
Schools use criterion-referenced tests to assess the specific knowledge and skills students have most likely learned in order to assess how close a student is to mastering a specific standard. We say âmost likelyâ because there is no absolutely perfect way to measure things we cannot directly see without some error.
