THE 1938 COOPERATIVE CHEMISTRY TEST The 1938 form of the Cooperative Chemistry Test will he available May 1, 1938. The test this year is divided into six sections, namely: information, vocabulary, problems, equations, application of principles, andinterpretation of experimental data. Some questions in qualitative analysis are included. In equations the students are required to give the product of the reaction, and balance, and to supply the formulas. Interpretation of experimental data, added for the first time, is designed to measure the student's ability to draw conclusions, to generalize, and to recognize the limitation of data. A set of data is given. and from this conclusions are drawn. or statements are made, as is commonly done by students. The examinee is required to indicate that the conclusion or statement given is correct, incorrect, or probable, or that the data are insufficient. The test has been pre-administered to a sufficient number of students to demonstrate that the questions are of the desired difficulty, are valid. and that the time limitations are just. The questions in each section are arranged in order of their difficulty and equitably weighted. The test is so arranged that it may be administered in one period of ninety minutes or two periods of forty-five minutes. Separate scoring sheets for manual or ma-
chine scoring are available if desired. The time of scoring may he materially shortened hv their use. Thirty leiding chemistry teachers read and criticized the test. It was re-written to meet their comments. Some statements of chemistry teachers about the test are as follows. "The 1938 form is a big improvement over last year's test." "On the whole the test is very thorough and representative of a year's work in general chemistry, including qualitative analysis. that is usually given." "The problems are a keen contribution to testing methods in chemistry." "The questions are thoughtfully designed to test the student's ability to use and to u understand chemical information, rather than a task of memory." The price is $5.00 per hundred or more, and orders should be sent to the Cooperative Test Service, 15 Amsterdam Avenue, New York. Manuals. scoring sheets. and report forms will be furnished with each order so that results may be used in the National Sophomore Testing Program. The Committee wishes that all the teachers would use these tests as part of their final examination and thus obtain the benefit to be derived from participation in this project-Cornmiltee on Examinations and Tests, O.
