Objective Tests in Organic Chemistry ED. F. DEGERING Prrrdwe Unitwrsity, Lofnyette, Indiono
HE NATION is workmg harder today than at any Tother . . . : tlme m its history, yet it is not necessary for one to slave a t a testing program in organic chemistry. Four complete sets of objective tests in organic chemistry are now available. These comprise the 194M1, the 194142, the 194243, and the 1943-44 series. Each of these series contains 27 subject examinations on the various topics of organic chemistry as: 1. 2. 3. 4.
5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. 16. 17. 18.. 19. 20. 21. 22. $3. 24. 25. 26. 27.
Alkanes, alkenes, alkynes. Alkyl halides and polyhaloalkanes. Alcohols, ethers, halohydrins, alkene oxides. Aldehydes, ketones, ketenes. Acids, saturated and unsaturated. Halogen, hydroxy, and 0x0-substituted acids. Anhydrides, acid halides, esters, salts. Replacement reactions, review. Carbohydrates. Final examination, Nos. 1-9. Thioalcohols, thioethers, sulfonic acids. Nitroparaffins, amides, urea, urea derivatives, amines, amino acids, proteins, nitriles, and isonitriles. Foods and metabolism. Metallic and nonmetallic alkyl compounds. Alicyclic compounds. Aromatic hydrocarbons. Aryl halogen compounds. Phenols, aryl alcohols, ethers. Aryl aldehydes, ketones, quinones. Aryl carboxylic acids. Aryl sulfonic acids. Atyl nitro compounds, amines, and diazonium salts. Heterocyclic and miscellaneous compounds. Antiseptics, dyes, stains, indicators. Terpenes, rubber, resins, fibers, and detergents. Processes, reactions, syntheses, tests. Final examinations, Nos. 11-26.
Each test contains 20 items of the multiple choice type, in which zero to five answers may be correct.
Both individual answers and various combinations of answers are employed. The completion time of each test is 20 or more minutes. The instructor may, however, select only such items as he desires to emphasize and thus cut the test to a ten- or even a five-minute quiz. These four series of tests have been compiled and edited by a volunteer group of collaborators. As a consequence it is likely that the tests are rather representative. These tests may be used advantageously with any textbook in any course in organic chemistry, for the individual tests cover specific areas of the subject. The tests are so arranged that they may be graded manually, by cutting out small rectangles below the answers on a master key, and then superimposing the key on the test paper to be graded. Where machine grading is available, the numbering of the items is such that two answer sheets are all that are required for a complete course in organic chemistry. These subject tests are available at 20 cents per set (20 cents per student per year) in lots of five or more, plus postage. Individual sets are priced at 50 cents. All orders for less than $2.00 should be accompanied by payment. These tests are available from the chairman of the committee, Ed. F. Degering, Department of Chemistry, Purdue University, Lafayette, Indiana. This is a nonprofit project, which has been subsidized by Purdue University from the outset. Two comprehensive objective tests in organic chemistry are also available, Form S and Form T. T h e ~ e are obtainable from the Cooperative Test Service, 15 Amsterdam Avenue, New York City, N. Y. These comprehensive tests contain 100 carefully selected items each, which give a representative coverage of a beginning course in organic chemistry. One hundred minutes are required for the completion of each of these examinations, but Form T is so designed that it may be given in two 50-minute periods. Cooperation in the production of subsequent sets of both of these series of tests is cordially invited.
