Randomized experiments are often seen as the "gold standard" for causal research. Despite the fact that experiments use random assignment to treatment conditions, units are seldom selected into the experiment using probability sampling. Very little research on experimental design has focused on how to make generalizations to well-defined…

This paper focuses generally on student non-cognitive improvement before and after a Newark Chapter 1 program implementation; and specifically, on demonstrated growth in the non-cognitive areas over the year from pre-assessment to post-assessment as part of the Chapter 1 intervention. The evaluation was conducted, based on classification in terms…

Final evaluation of a 3-year project to use microcomputers to improve the reading and language skills of Limited English Proficient (LEP) Native American students revealed that there was significant growth evidenced in over 75% of the reading subscale groupings as measured by the Comprehensive Tests of Basic Skills (*CTBS). Subjects were 114…

In studying the effectiveness of different instructional programs, a criterion measure can favor one of the programs because there is greater overlap between the content covered on the test and in that program. This overlap can be measured using teacher estimates or teacher estimates combined with curriculum analysis. (Author/BW)

The Reading Strategy Project is designed for intermediate grade students who need assistance in the mastery of basic reading skills. The available data demonstrated that the Title I treatment group enhanced their average reading comprehension scores significantly. The gain exceeded the project objective of four normal curve equivalent points. The…

Statistical evaluation indicated the effectiveness of 10 software packages used in a 3-year project to improve the reading and language skills of Limited English Proficient (LEP) Native American students. The project was implemented in four Rapid City (South Dakota) schools in which 79% of the Lakota (Sioux) Indian students (grades 3-6) were found…

Results of a pilot follow-up study conducted on Spanish dominant students in transition from bilingual programs to English only instructional settings was reported. The sample group was predominantly Mexican American and native Mexican students. Three types of data were collected: individual scores on Comprehensive Test of Basic Skills (CTBS),…

This paper describes the extent to which the Gender Expectations and Student Achievement (GESA) program has been disseminated at the national level, reports the findings of a validation study conducted in a California school district, and shares recommendations for further study and future plans. GESA was designed to reduce the disparity in the…

Value-added models, which rate schools for effectiveness while taking into account the poverty and other socioeconomic status of the students, are generating increased interest. This paper describes the use of one such model to evaluate whether school ratings changed when three new programs were introduced: the "Target Teach" curriculum…

The Primary Reading Program was initiated in 117 classrooms in 40 North Carolina schools, to improve the reading achievement of the primary school students. The same number of control classrooms were also selected for comparison. Features of the program included increased funding for instructional materials; use of volunteers and teacher aides for…

Normative data reported by publishers of the California Achievement Test, the Comprehensive Tests of Basic Skills, and the SRA Assessment Survey were used to illustrate a procedure for specifying goals for Title I programs in terms of normal curve equivalent (NCE) gains. The procedure was based on the amount of growth reflected in student reading…

When a program evaluation is conducted on the basis of gains made in standardized achievement test scores between a pretest and a posttest, serious bias can result where a floor effect exists on one or both of the test levels. Based upon the expanded standard scores on the Comprehensive Tests of Basic Skills from three successive regular spring…

This study evaluated the implementation of and the outcomes from a local child parent center compensatory education program. It intended to contribute to a better understanding of one phase of compensatory education; and, in the process, it proposed to develop a relatively simple and practical evaluation strategy which would verify the…

The validity of the Comprehensive Tests of Basic Skills (CTBS) and problems associated with inappropriate norms were investigated in eleven senior high schools in Phoenix, Arizona. CTBS validity was assessed in three ways: (1) correlation between test scores and number of courses taken in that subject; (2) correlation between CTBS scores and…

The School Improvement Program (SIP) was implemented in 5 Columbus (Ohio) public schools during the 1982-83 school year, 18 public schools during the 1983-84 school year, 26 public schools during the 1984-85 school year, and 15 public schools during the 1985-86 school year. The objective of SIP was to improve the academic achievement of students…
