The purpose of this publication is to provide an overview of sampling procedures for obtaining data to evaluate Extension programs. This is especially useful in telephone surveys, where the interviewer can abbreviate the interview if the respondent does not meet the selection criteria and save valuable time and money.
If either of these conditions is absent from the design, there is potential for bias in the estimates of program effect" Rossi et al. This would include driving across the county and stopping at farms not on the citrus list.

What will be evaluated? The Research Impact evaluation of extension programs The first step in determining the sampling procedures to be used in an evaluation is a clear statement of the research or evaluation problem.
However, many continuing education programs make heavy use of distance educationwhich not only includes independent study, but can also include videotaped material, broadcast programming or online education which has more recently dominated the distance learning community.
A proportionate or equal size stratified sample would produce statistics with the same precision for each group assuming equal variancesand for the total population.
Impact heterogeneity refers to differences in impact due by beneficiary type and context. The above questions suggest that the purpose of the evaluation can vary. It is a practical, nonprescriptive tool, designed to summarize and organize the essential elements of program evaluation.
The recommended framework was developed to guide public health professionals in using program evaluation. Products under SLEP are regularly retested and must be destroyed if at any time they fail testing.
Self-selection occurs where, for example, more able or organized individuals or communities, who are more likely to have better outcomes of interest, are also more likely to participate in the intervention. McCumiskey and Tim L.
As noted in the Cornell Era of February 16,the university offered a "Tour of the Great Lakes" program for "teachers and others" under the direction of Professor Theodore B. To illustrate the process of selecting a stratified random sample, refer to Figure 3. The random assignment of individuals to program and control groups allows for making the assumption of continuing equivalence.
One alternative is to look for another list to use as the sampling frame. These operating principles imply several ways to improve how public health activities are planned and managed. Select numbers from the table.
SLEP is administered by the U. Liability fears can arise among healthcare providers and others dispensing the shelf-life-extended items. One way to do this is to sample farmers but with of those being 65 years of age or older.
Random sample surveys, in which the sample for the evaluation is chosen randomly, should not be confused with experimental evaluation designs, which require the random assignment of the treatment. Non-experimental designs are the weakest evaluation design, because to show a causal relationship between intervention and outcomes convincingly, the evaluation must demonstrate that any likely alternate explanations for the outcomes are irrelevant.
These information-sharing strategies provided the working group numerous opportunities for testing and refining the framework with public health practitioners. Representative samples of the drugs nominated for participation in SLEP are taken from specific lot numbers at one stockpile location and shipped to an FDA field laboratory for testing.
What factors may influence test results? Defining Key Concepts Throughout this report, the term program is used to describe the object of evaluation, which could be any organized public health action. To illustrate, suppose we wish to evaluate a statewide program in energy conservation with a face-to-face survey of 1, households.
How will the lessons learned from the inquiry be used to improve public health effectiveness? Approximately 90 representatives participated.
Furthermore, it is possible that program participants are disadvantaged if the bias is in such a way that it contributes to making an ineffective or harmful program seem effective. These biases affect the interest of the stakeholder.
One method to overcome this deficiency is to specify a procedure based on location or some other known characteristic. Tim is supported in ministry by his home congregation in Sheffield, Tasmania where he serves primarily as a Bible teacher.
Figure 2 illustrates this simple random sample of 20 Note: Then, those numbers selected from a table of random numbers or randomly generated by a computer program are included in the sample.This paper examines the interplay between Malawi’s input subsidy and access to extension services, and the impact of both on farm productivity and food security using.
Logic Models are a popular tool that can be used to help conceptualize your change effort. It does this by inviting the author(s) to articulate their understanding of the current situation, the changes they hope to bring about through their program effort, with and/for whom, the activities planned to contribute toward this change, the resources needed to put into the effort, assumptions they.
American Institutes for Research Evaluation of the Regional Extension Center (REC) Program—i American Institutes for Research conducted an evaluation of the Regional Extension Center Program for the Office of the National Coordinator for Health Information Technology (ONC).
Similarly, according to the US Environmental Protection Agency impact evaluation is a form of evaluation that assesses the net effect of a program by comparing program outcomes with an estimate of what would have happened in the absence of a program.
UW-Extension works with the people of Wisconsin to solve their most pressing issues and uncover their most promising opportunities through hundreds of programs and initiatives statewide. Performance Evaluation Tests. Performance is an assessment of how well a task is executed and the success of a training program is largely dependent upon satisfying the performance aims associated with it.Download
