<p><em>This quantitative, quasi-experimental design study examined 75 pre-service teachers’ perceptions of their own self-efficacy regarding</em><em> </em><em>classroom management. Data was collected at three different intervals throughout the student teaching experience, which was also accompanied by a training seminar focusing on classroom organization and management (Classroom Organization and Management Program). Results showed that pre-service teachers exhibited significantly higher perceptions of self-efficacy at different intervals throughout their student teaching. Data from this study provides Educator Preparation Programs (EPPs) with further data, which will allow them to create program curricula and strategies to better prepare pre-service teachers to become successful and confident classroom teachers. </em><em></em></p><em></em><em></em>

This article reviews research on the achievement outcomes of elementary mathematics programs; 87 rigorous experimental studies evaluated 66 programs in grades K–5. Programs were organized in six categories. Particularly positive outcomes were found for tutoring programs (effect size [ES] = +0.20, k = 22). Positive outcomes were also seen in studies focused on professional development for classroom organization and management (e.g., cooperative learning; ES = +0.19, k = 7). Professional development approaches focused on helping teachers gain in understanding of mathematics content and pedagogy had little impact on student achievement. Professional development intended to help in the adoption of new curricula had a small but significant impact for traditional (nondigital) curricula (ES = +0.12, k = 7), but not for digital curricula. Traditional and digital curricula with limited professional development, as well as benchmark assessment programs, found few positive effects.

The Delphi Technique of survey and consensus-building was used to obtain ratings from experienced teachers to four questions related to their professional preparation. 13 teachers with varying amounts of experience completed four rounds of questioning over a 14-wk. period. The highest-rated responses indicated teachers' perceived importance of classroom organization and management skills, lesson design and delivery skills, and a “humanistic” orientation toward pupils. These perceptions were considered in relation to conclusions from research on effective teaching.

As part of a continual search for potential pathogens of insects for use in biological control or on an integrated pest management program, two bacilliform virus-like particles (VLP) of similar morphology have been found in the Mexican bean beetle Epilachna varivestis Mulsant and the house cricket, Acheta domesticus (L. ).Tissues of diseased larvae and adults of E. varivestis and all developmental stages of A. domesticus were fixed according to procedures previously described. While the bean beetles displayed no external symptoms, the diseased crickets displayed a twitching and shaking of the metathoracic legs and a lowered rate of activity.Examinations of larvae and adult Mexican bean beetles collected in the field in 1976 and 1977 in Maryland and field collected specimens brought into the lab in the fall and reared through several generations revealed that specimens from each collection contained vesicles in the cytoplasm of the midgut filled with hundreds of these VLP's which were enveloped and measured approximately 16-25 nm x 55-110 nm, the shorter VLP's generally having the greater width (Fig. 1).
