Condensed Norms:

ACS Cooperative Examinations

I n the spring of 1966 five new tests were relessed: Quantitative Analysis Form 1966; Instrumental Analysis Form 1966; Inorganic Chemistry Form 1966; High School Chemistry Form 1966ADV and High School Chemistry Form 1965s. The condensed norms are selected from a larger body of data which can be obtained from the Examinations Committee, American Chemical Society, Theo. A. Ashfard, Chairman, University of South Florida, Tamps, Fla. 33620. Condensed norms far the currently used ACS Cooperative Examinations may he found in J. CHEM.ED.,34, 144 (1957); 35, 244 (1958); 36, 148 (1959); 37, 166 (1960); 38, 211 (1961); 39, 151 (1962); 40, 144 (1963); 41, 166 (1964); 42, 170 (1965); 43, 217 (1966).

The scoring formulas used were R-W/4, 2R-W/4 for Part I and Part I1 respectively. The figures given are raw scores. The reliability coefficient was estimated by the Knder-Richardson Fam.nla No. 21. a Sub-groilp A consists of 153 Sophomores, Juniors, and Seniors (81% Juniors) who have had no c o l w e in Physics, 2 semesters of Chemistry, and 4-6 semesters of i\lathematics (If = 5.5) prior to taking this chemistry course. Sub-group B consists of 256 Juniors and Seniors (98.9% Seniors) who have had 2 semesters of Physics, 4 semesters of chemistry, and 6-10 semesters of Mathematics (M = 8.0) prior to taking this chemistry course.

Reliability coefficient The swrina formula. used was R-Wl4 The figuresgiven are raw scores. The reliability coefficient was estimated by the Kuder-Richardson Formula No. 21. The group consists of 206 students in 26 institutions. All but two schools specified one or two semesters of physical chemistry. At least twa-thirds (2/a) specified one semester of quantitative chemistrv. ~resumablvall have had some. All schools reauired a t least Ge-year of ph&s with a mean of 9.3 semester ha& and a t least 6 semester hours in mathematics with a mean of 10.4. Lecture hours ranged from 2-3 with a, mean of 2.2. Laboratory hours ranged from 4-8 with a mean of 6.0.

Program of the Examinations Committee Five new tests have been published for 1967:

General Chemistry Form 1967. A 105-min modern examination covering: atomic and nuclear structure, molecular structure and bonding, stoichiometry, states of matter, kinetics, thermodynamics, acid-base theory, equilibrium, electrochemistry, and descriptive chemistry. Brief Qualitative Analysis Form 1967. A 50-min test for one semester qualitative analysis students or may be given as a supplement with any test in general chemistry.

Organic Chemistry Form 1967B. An 80-min test covering the subject matter of a brief course, such as nomenclature, functional group reactions, analytical deductions, and some theoretical concepts.

High School Chemistry Form 1967. An 80-min test designed to test the students who have had some stress placed on the learning of skills, principals, and concepts in the first year chemistry course. Graduate Level Placement Ezarnination in Physical Chemistry Form 1967-P.

The group oonsists of 216 students in 15 institutions. All schools required at least 8 semester hours in chemistry prior to taking this wurse. AU but three schools specdied at least one year of mathematics, presumably dl have had some. Lecture hours ranged from 2-3 with s mean of 2.4. Laborstory hours ranged from 3-8 with a meen of 5.5.
