Superintendents and school boards must balance state and federal mandates, requirements of new legislation, and policy changes as they search for best practices in education that will result in increased student achievement. Pressure has increased, with an emphasis on high stakes testing and accountability since the implementation of the No Child…

Empirical Education Inc. is the independent evaluator of WestEd's 2012 i3 Development grant for Internet-based Reading Apprenticeship Improving Science Education (iRAISE). This interim report provides an update on the progress of the randomized control trial (RCT) during the 2014-2015 school year. The RCT measures the impact of iRAISE on student…

The major purpose of this paper is to examine the problems of geralizing from the Graduated Work Incentive experimental setting to the national labor-supply responses that would be generated by a negative income tax that replaced existing welfare programs for families headed by able-bodied males. (Author/BP)

Among the many problems in interpreting the results of the experiment is the determination of what can be inferred from a limited duration experiment about the behavioral effects of a negative income tax. This paper examines and interprets experimental data based on the labor supply model. (Author/BP)

THIS WORKING PAPER OFFERS A BRIEF DESCRIPTION OF THE UTILIZATION OF COMPUTERS AS CONTROL DEVICES, LISTING BOTH THEIR ADVANTAGES AND DISADVANTAGES. SUCH OTHER APPLICATIONS AS SIMULATION AND "DATA PROCESSING" WERE NOT COVERED IN THIS DOCUMENT. (LP)

A VOLUNTEER, EXTRA-CURRICULAR PROGRAM FOR GIFTED STUDENTS IS DESCRIBED. TWO MAIN PURPOSES ARE--TO INTEREST AND STIMULATE GIFTED STUDENTS IN THE DEVELOPMENT AND BROADENING OF THEIR PERSPECTIVES IN THE SCIENCE AND MATHEMATICS FIELDS AND TO ENCOURAGE THESE STUDENTS TO UNDERTAKE A PROJECT IN THE FIELDS OF SCIENCE OR MATHEMATICS, IN THE NATURE OF…

THE EFFECTS OF THREE SIZES-OF-STEP AND THE TYPE AND AMOUNT OF CUEING UPON ACHIEVEMENT IN SPELLING WERE COMPARED. NINETY-SIX FIFTH-GRADE PUBLIC SCHOOL STUDENTS WERE RANDOMLY ASSIGNED TO ONE OF SIX EXPERIMENTAL TREATMENTS. ALL SUBJECTS WERE MATCHED ON SEX BEFORE ASSIGNMENT. THE MEAN SCORES ON EACH OF THE WEEKLY TESTS WERE COMPARED BY AN ANALYSIS OF…

THE INTEGRATION OF WORDS AND PICTURES IN THE TWO STUDIES REPORTED IN THIS VOLUME WAS ACCOMPLISHED UNCONVENTIONALLY. IN ONE STUDY, AN ENTIRE TOPIC, ARCHIMEDES' LAW, WAS COVERED IN A SELF-CONTAINED, ENTIRELY PICTORIAL LESSON AND ALSO IN A SELF-CONTAINED, ENTIRELY VERBAL LESSON. STUDENTS ACQUIRED ALL THE CONCEPTS AND PRINCIPLES MAKING UP ARCHIMEDES'…
