Technology was integrated into service-learning activities to create an interactive teaching method for undergraduate students
at a large research institution. Chemistry students at the University of Central Florida partnered with high school students
at Crooms Academy of Information Technology in interactive service learning projects. The projects allowed UCF students to
teach newly acquired content knowledge and build upon course lecture and lab exercises. Activities utilized the web-conferencing
tool Adobe Connect Pro to enable interaction with high school students, many of whom have limited access to supplemental educational
opportunities due to low socioeconomic status. Seventy chemistry I students created lessons to clarify high school students’
misconceptions through the use of refutational texts. In addition, 21 UCF students enrolled in the chemistry II laboratory
course acted as virtual lab partners with Crooms students in an interactive guided inquiry experiment focused on chemical
kinetics. An overview of project’s design, implementation, and assessments are detailed in the case study and serve as a model
for future community partnerships. Emerging technologies are emphasized as well as a suggested set of best practices for future
projects. 相似文献

Predoctoral interns' responses to an internship supervision training questionnaire indicated that counseling center interns supervised more trainees, received more supervision in their supervisory roles, reported more supervision training activities, and yielded higher supervisor development scores than did non‐counseling‐center interns. A qualitative analysis of participants' responses showed that non‐counseling‐center interns desired more supervision training and opportunities to provide supervision during their internship year than did counseling center interns. 相似文献

The separate effects of child neglect, abuse, and their interaction upon language development as measured by the Preschool Language Scale were examined in four groups of children (n = 79) in a quasi-experimental design. There were three groups of maltreated subjects, all drawn from a treatment center: an abused only group (n = 13), a neglected only group (n = 7), and an abused and neglected group (n = 31); a non-maltreated group (n = 28) was drawn from a day care center. Abuse, neglect, and their interaction were used to predict both auditory comprehension and verbal ability as separate criteria in two stepwise multiple regression equations, where the variance attributable to gender and mother's status on Aid to Dependent Children had been removed. Child neglect was found to predict significantly both auditory comprehension and verbal ability. Neither child abuse nor the interaction between abuse and neglect significantly predicted either dependent variable. These findings suggest that child neglect may be the critical type of maltreatment associated with language delay. 相似文献
