Parent Involvement in Homework: A Research Synthesis
New emphasis is being placed on the importance of parent involvement in children's education. In a synthesis of research on the effects of parent involvement in homework, a meta-analysis of 14 studies that manipulated parent training for homework involvement reveals that training parents to be involved in their child's homework results in (a) higher rates of homework completion, (b) fewer homework problems, and (c) possibly, improved academic performance among elementary school children. A meta-analysis of 22 samples from 20 studies correlating parent involvement and achievement-related outcomes reveals (a) positive associations for elementary school and high school students but a negative association for middle school students, (b) a stronger association for parent rule-setting compared with other involvement strategies, and (c) a negative association for mathematics achievement but a positive association for verbal achievement outcomes. The results suggest that different types of parent involvement in homework have different relationships to achievement and that the type of parent involvement changes as children move through the school grades.

Does homework improve academic achievement?
In this article, research conducted in the United States since 1987 on the effects of homework is summarized. Studies are grouped into four research designs. The authors found that all studies, regardless of type, had design flaws. However, both within and across design types, there was generally consistent evidence for a positive influence of homework on achievement. Studies that reported simple homework-achievement correlations revealed evidence that a stronger correlation existed (a) in Grades 7-12 than in K-6 and (b) when students rather than parents reported time on homework. No strong evidence was found for an association between the homework-achievement link and the outcome measure (grades as opposed to standardized tests) or the subject matter (reading as opposed to math). On the basis of these results and others, the authors suggest future research. (DIPF/Orig.).

Effectiveness of Mentoring Programs for Youth: A Meta‐Analytic Review
We used meta‐analysis to review 55 evaluations of the effects of mentoring programs on youth. Overall, findings provide evidence of only a modest or small benefit of program participation for the average youth. Program effects are enhanced significantly, however, when greater numbers of both theory‐based and empirically based “best practices” are utilized and when strong relationships are formed between mentors and youth. Youth from backgrounds of environmental risk and disadvantage appear most likely to benefit from participation in mentoring programs. Outcomes for youth at‐risk due to personal vulnerabilities have varied substantially in relation to program characteristics, with a noteworthy potential evident for poorly implemented programs to actually have an adverse effect on such youth. Recommendations include greater adherence to guidelines for the design and implementation of effective mentoring programs as well as more in‐depth assessment of relationship and contextual factors in the evaluation of programs.

Interventions to increase physical activity among aging adults: A meta-analysis
This review applied meta-analytic procedures to integrate primary research findings that test interventions to increase activity among aging adults.
We performed extensive literature searching strategies and located published and unpublished intervention studies that measured the activity behavior of at least five participants with a mean age of 60 years or greater. Primary study results were coded, and meta-analytic procedures were conducted.
The overall effect size, weighted by sample size, was d(w) = .26 +/- .05. Effect sizes were larger when interventions targeted only activity behavior, excluded general health education, incorporated self-monitoring, used center-based exercise, recommended moderate intensity activity, were delivered in groups, used intense contact between interventionists and participants, and targeted patient populations. Effect sizes were larger for studies that measured exercise duration and studies with a time interval of less than 90 days between intervention and behavior measurement.
These findings suggest that group-delivered interventions should encourage moderate activity, incorporate self-monitoring, target only activity, and encourage center-based activity. Findings also suggest that patient populations may be especially receptive to activity interventions. Primary research testing interventions in randomized trials to confirm causal relationships would be constructive.

The Effects of Summer Vacation on Achievement Test Scores: A Narrative and Meta-Analytic Review
A review of 39 studies indicated that achievement test scores decline over summer vacation. The results of the 13 most recent studies were combined using meta-analytic procedures. The meta-analysis indicated that the summer loss equaled about one month on a grade-level equivalent scale, or one tenth of a standard deviation relative to spring test scores. The effect of summer break was more detrimental for math than for reading and most detrimental for math computation and spelling. Also, middle-class students appeared to gain on grade-level equivalent reading recognition tests over summer while lower-class students lost on them. There were no moderating effects for student gender or race, but the negative effect of summer did increase with increases in students’ grade levels. Suggested explanations for the findings include the differential availability of opportunities to practice different academic material over summer (with reading practice more available than math practice) and differences in the material’s susceptibility to memory decay (with fact- and procedure-based knowledge more easily forgotten than conceptual knowledge). The income differences also may be related to differences in opportunities to practice and learn. The results are examined for implications concerning summer school programs and proposals concerning school calendar changes
