The purpose of this study is to develop a model showing the relationship of academic, socioeconomic, and motivational variables to students' attrition in a community college nursing program, in order to determine the students who pass, or not pass, first semester, generic, and associate degree nursing courses. The theoretical framework used in the…

Standard practice in educational program evaluation expends considerable resources in planning and executing elaborate research designs, but lacks description of how the programs do differ in the experimental'' and control'' situations. A serious consequence is that elaborately designed evaluation studies may end up appraising non-events, with…

Students in an open study hall system with a student lounge option received lower grades than students without the option. To prevent this, it is suggested that wise use of unstructured time be planned. (AP)

An experimental project in the teaching of biology is discussed. (CK)

The learning and retention performances of children and adults were compared on free and serialized reproductions of meaningful words.

Self-reinforcement by 74 children of age five years for asking questions in a small group with one trainer, then in a large group with another person, showed that self-reinforcing children had learned to ask questions but the behavior did not transfer to the new situation. (Author)

The desirability of combining tests of theory with evaluations of treatment modalities is argued in an investigation of the effectiveness of a juvenile diversion program. Using a true experimental design (with randomization), recidivism analyses dependent on court record data failed to demonstrate the relative superiority of any of three treatment…

Children 3 to 6 years of age learned simple Spanish vocabulary items using an adaptation of the keyword method of foreign language vocabulary learning.

The problems of the use of humans as subjects of medical research and the protection of their rights are discussed. Issues include the use of informed consent, the evaluation of risks and benefits, and the review of research plans by a committee. (JD)

School counselors need to know which methods work best with their students. One means of determining this is presented. Limitations exist in the generalizability of findings. A major feature of intensive experimental designs is that large numbers of students are not needed to conduct meaningful evaluation of an intervention. (Author/BEF)

Hoyt recommends the use of norm groups, to adjust student ratings of instruction. Prior methods of generating norm groups relied upon the use of volunteer subjects. Results of the present study indicate that volunteer teachers' student ratings were superior to nonvolunteer teachers' ratings. (Author/RD)
