Abstract The article discusses how sections of a video can best be used in the instructional process by activating the minds of students and using their reactions to viewing to produce intellectual action. It gives some suggested schemes for this activity and shows how technological forces can become energies of change. 相似文献

Although research on Tier 2 interventions for early mathematics is accumulating, such efforts remain far behind those for reading, especially regarding specific features such as the ideal time to begin an intervention. The present study investigated the effectiveness of a Tier 2 intervention using a single subject multiple baseline, across-groups design with two cohorts of second graders. Because the two cohorts of students were given the intervention at different times during the second grade year, the study also documented whether the timing of the intervention affected acquisition and retention of second grade mathematics competencies. Finally, the study tracked student performance up to the first semester of the third grade year to document any sustained effects. The results show that the supplemental intervention was effective for both cohorts, but differences in performance indicate that the timing of the intervention may affect the degree of success. In addition, for some participants, the positive effects of the intervention were sustained into the third grade year. 相似文献

Researchers and practitioners require guidelines for using electronic pedometers to objectively quantify physical activity (specifically ambulatory activity) for research and surveillance as well as clinical and program applications. Methodological considerations include choice of metric and length of monitoring frame as well as different data recording and collection procedures. A systematic review of 32 empirical studies suggests we can expect 12,000-16,000 steps/day for 8-10-year-old children (lower for girls than boys); 7,000-13,000 steps/day for relatively healthy, younger adults (lower for women than men); 6,000-8,500 steps/day for healthy older adults; and 3,500-5,500 steps/day for individuals living with disabilities and chronic illnesses. These preliminary recommendations should be modified and refined, as evidence and experience using pedometers accumulates. 相似文献
