Comprehensive Family Services (CFS) is a strengths-based and partnership-oriented approach to casework implemented through multiple initiatives. This study examines the relationship between the practice of CFS and satisfaction of clients, foster parents, and community partners. CFS indicators are paired with statewide customer satisfaction survey…

The evaluation of the Voyager Universal Literacy System[R] was designed to provide a rigorous assessment of the effectiveness of the program with beginning readers. Using a quasi-experimental design, researchers conducted a systematic evaluation of changes in 398 kindergarten students' command of early reading skills in 4 Voyager and 4 comparison…

This paper focuses on transition programs for youth to postsecondary education, broadly considered. It addresses the following questions: (1) What models or programs of transition exist? (2) On what basis can we say one transition program is more effective than another? In other words, how is successful transition defined? (3) How are…

This paper presents the development of a 3-D virtual environment in Second Life for the delivery of standards-based science content for middle school students in the rural Appalachian region of Southeast Ohio. A mixed method approach in which quantitative results of improved student learning and qualitative observations of implementation within…

Web 2.0 software, in particular wikis, have the potential to allow students to become active contributors to the Internet and, as a result, restructure traditional learning environments. In this study, the effects of student-created wikis were evaluated through measures of student engagement, cognitive benefits, and student learning in both the…

The "Bilingual Cooperative Integrated Reading and Composition" ("BCIRC") program, an adaptation of the "Cooperative Integrated Reading and Composition" ("CIRC") program, was designed to help Spanish-speaking students succeed in reading Spanish and then making a successful transition to English reading. In…

In an effort to overcome deficiencies in teaching molecular biology at school, a workshop in an out-of-school laboratory including only authentic experiments was developed. Evaluation of 337 A-level 12th graders followed a quasi-experimental design, with one hands-on group, two non-experimental control groups (at school/in the laboratory), and one…

This paper comments on strengths and weaknesses of the papers on communities of practice in this special issue of "Technology, Pedagogy and Education." First it discusses the character of communities of practice and the question of whether schools are environments that are conducive to the development of teacher communities of practice. It then…

In order to determine the extent to which the LOGO programming language can be used as a reinforcer for general problem solving ability, this field study used a production theory approach to problem solving as a conceptual model, and then translated the model into a LOGO oriented framework. The methodology tested the use of an algorithm in a…

A relationship between experimental and statistical controls is considered in an effort to show how this relationship affects the power of an experiment. Statistical rather than experimental controls are often used to reduce the effect of subjects at the extremes of individual difference. This results in attrition of actual experimental subjects.…

Describes how the lost letter technique, a research ploy involving leaving stamped, addressed letters in public locations and seeing if people will mail them, may be used to introduce students to experimental method in sociological research. Students manipulated letter location, size, and address in order to judge different effects such variations…

The purposes of evaluation design are stated. A description of experimental, quasi-experimental, survey, and naturalistic designs is presented. Emphasis is placed upon the identification of sources of invalidity in these designs that may compromise the accuracy of inferences regarding program effectiveness. (Author/JAZ)

The regression-discontinuity design (RDD) offers the possibility of making inferences about causal effects from observations on selected groups. Data from such a design are considered to have a truncated bivariate distribution. For the RDD, maximum likelihood parameter estimation procedures and tests of hypotheses are presented. (Author/BW)

A theoretical model of an effective experiential educational program for training evaluators is described. Two operating programs are assessed against the requirements of the model. The results of a quasi-experimental evaluation of the effectiveness of the programs in producing important educational outcomes are reported. (Author/PN)

Criteria for suitable research designs for use with large databases are suggested and analyzed. The advantages and disadvantages of several types of quasi-experimental designs are compared. Examples are taken from the authors' research with data from the Manitoba Health Services Commission. (Author/AL)
