Educare is a birth to age 5 early education program designed to reduce the achievement gap between children from low‐income families and their more economically advantaged peers through high‐quality center‐based programming and strong school–family partnerships. This study randomly assigned 239 children (< 19 months) from low‐income families to Educare or a business‐as‐usual control group. Assessments tracked children 1 year after randomization. Results revealed significant differences favoring treatment group children on auditory and expressive language skills, parent‐reported problem behaviors, and positive parent–child interactions. Effect sizes were in the modest to medium range. No effects were evident for observer‐rated child behaviors or parent‐rated social competence. The overall results add to the evidence that intervening early can set low‐income children on more positive developmental courses. 相似文献

Lichens are a good example of the virtues of simplicity and cooperation. They survive in extremes of climatic conditions,
ranging from low tide level on the sea shore to the high reaches of the Himalaya, beyond the tree line, in the arctic Tundra. 相似文献

Students entering higher education need to integrate themselves into a new study community. Those coming from minority ethnic backgrounds may experience this phase more intensely since they may feel themselves to be different or consider that they are being treated differently. This article approaches ethnic identity as a dynamic concept. The differences characterizing students with varying ethnic self‐definitions are explored as subjective factors that are important for good study progress. Finally, study progress after one year is analyzed. 相似文献

The present contribution focuses on an interactive learning environment for the delivery of distance education learning materials. The use of such an interactive learning environment is foreseen in a distance education context in which students explore and study (part) of the learning materials by means of a personal computer. Research with interactive learning environments is transposed to the development of a course delivery environment, called ILCE, that also supports the development of a course model and learning materials. A learning environment as used in the present study allows students to access the course materials in a more flexible way. The printed self-study materials often do not correspond with the specific needs of a student, are only weakly related to his or her prior knowledge, or do not take account of differences in learning style. Although the printed course materials include text-embedded support devices (e.g., examples, exercises, illustrations), it is questioned whether the available devices provide enough support for each individual student. Therefore, it is argued that an interactive learning environment — in which a student is actively engaged in selecting learning materials (basic content and embedded support devices) — may provide a valuable tool in order to meet the individual needs of the student. Prototypes of an interactive learning environment were tested in two experimental settings. It appeared that all students were actively engaged in selecting the required support devices. However, the results showed that students with a high prior knowledge state manifested a higher amount of interactive use of support devices than their peers with a low prior knowledge state. The latter was especially found for support devices that either reinforce the acquisition process or provide a tool to test one’s mastery level. 相似文献
