Predictors of caregiver burden in caregivers of individuals with dementia.

AIMS This article is a report on a study of the multidimensional predictors of caregiver burden in caregivers of individuals with dementia using nationally representative data. BACKGROUND Caregiver burden affects the health of both caregivers and their care-recipients. Although previous studies identified various predictors of caregiver burden, these predictors have not been confirmed in nationally representative population. METHODS Data for this secondary analysis was provided by the National Alliance for Caregiving, American Association of Retired Persons. The data were collected through a telephone survey of randomly selected adults in seven states in 2003 (weight adjusted n = 302). Descriptive statistics, inter-correlation analysis and a hierarchical multiple regression analysis were performed. RESULTS/FINDINGS Disease-related factors were the most significant predictors, explaining 16% of caregiver burden; these were followed by caregiver socio-demographical factors and caregiving-related factors (F = 21·28, P < 0·01). Significant individual predictors were impairment of activities of daily living or instrumental activities of daily living, the number of hours of caregiving, use of coping strategies, co-residence, spousal status and caregiver gender (P < 0·05). CONCLUSION Impaired function in care-recipients predicts caregiver burden, and also interacts with demographical- and caregiving-related factors. Thus, it will be beneficial to both care-recipients and caregivers to target nursing interventions and community services to improve the functional abilities of individuals with dementia.

Parental Involvement, Parenting Behaviors, and Children's Cognitive Development in Low-Income and Minority Families

Abstract The study examined the longitudinal association of parental involvement in Head Start parent-focused programs, parenting behaviors, and the cognitive development of children by specifying two longitudinal growth models. Model 1 examined the longitudinal effects of the parental involvement in three Head Start parenting programs (parenting classes, group socialization, and support groups) on parenting behaviors (home observation of parental linguistic and cognitive stimulation, video recordings of parental cognitive stimulation, parental sup-portiveness, detachment, and intrusiveness). Model 2 analyzed the longitudinal effects of those parental behaviors on childrens Bayley MDI scores. Using Early Head Start Research and Evaluation (EHSRE) study data and longitudinal multilevel analysis, the study also took various ethnic and language differences among families into account. The results revealed that mothers who participated in parenting classes or socialization meetings provided more linguistic and cognitive stimulation at home. Participants of parental support groups were found to have high levels of parental supportiveness and low levels of parental intrusiveness over time. Higher Bayley MDI scores were found for children whose mothers had high levels of parental involvement in Head Start parent programs and provided more at-home linguistic and cognitive stimulation. The African American families, in particular, benefited from attending socialization meetings: attendees displayed fewer parental detachment behaviors and provided more linguistic and cognitive stimulation, resulting in higher Bayley MDI scores of children. The studys findings are theoretically significant and policy relevant.

Does Computer Use Promote the Mathematical Proficiency of ELL Students

The study explored the effects of computer use on the mathematical performance of students with special attention to ELL students. To achieve a high generalizability of findings, the study used a U.S. nationally representative database, the Early Childhood Longitudinal Survey Kindergarten Cohort (ECLS-K), and adopted proper weights. The study conducted both cross-sectional and longitudinal analyses to examine the direct and longitudinal effects of three types of computer use: home computer access, computer use for various purposes, and computer use for math. The study found positive effects of home computer access and computer use for various purposes for English-speaking groups. It is important to note that computer use for math was associated with a reduced gap in math achievement between native English-speaking and ELL students. In particular, when Hispanic and Asian students frequently used computers for math, they showed high math performances when compared with their English-speaking counterparts.

Science Engagement and Science Achievement: Longitudinal Models Using NELS Data.

The study explored the relationship of self-concept and locus of control to science engagement and science achievement. Furthermore, the relationship of self variables with science engagement and science achievement was studied across ethnicity, gender, and socioeconomic status (SES). The data were accessed from the 3 waves of the National Education Longitudinal Study: 88 (NELS:88) to estimate both cross-sectional and multilevel longitudinal models. It was hypothesized that self-concept and locus of control would have a positive effect on science engagement and science achievement and that science engagement would affect science achievement positively. The results supported the theoretical formulations of the conceptual model and showed significant effects of self-concept and locus of control constructs on science engagement and science Item Response Theory (IRT) scores. Furthermore, science engagement showed a positive but small effect on science achievement, especially the time spent on science homework. The study supported earlier findings that the inclusion of non-ability factors improves the explanation and understanding of differences in science achievement. The study has implications for practice.

Teacher Instructional Practices and Language Minority Students: A Longitudinal Model.

The author examined the long-term effects of teacher instructional grouping practices on the early mathematical achievement of language minority students from various ethnic groups. The study used 3 longitudinal models. In the 1st model, English language learners (ELLs) displayed lower math performance than did English-only students in the Hispanic and Asian groups. The 2nd model confirmed the significance of social class across all groups. The 3rd model focused on 4 grouping practices: (a) teacher-directed wholeclass activity, (b) teacher-directed small-group activity, (c) teacher-directed individual activity, and (d) student-selected activity. Significant findings include that (a) Hispanic ELL students displayed low math performance in teacher-directed whole-class activities, (b) Asian ELL students showed low math performance in teacher-directed small-group activities, and (c) Hispanic dual-language students benefited from teacher-directed individual activities.

Language factors associated with achievement grouping in math classrooms: a cross-sectional and longitudinal study

The study examines the effects of classroom achievement grouping (AG) practices on the early mathematics performance of language-minority students and compares their mathematics achievement to that of English-speaking majority students. Using a nationally representative database of the USA, both cross-sectional and longitudinal analyses were done. In the cross-sectional analyses we explored the direct effect of grouping practice on students performance, while in the longitudinal analysis we looked at the growth trajectory in mathematics learning. The results of cross-sectional analyses indicated that the effect of AG was negative on the math achievement in 1st and 5th graders. The longitudinal analysis showed a significant negative effect of AG for English Language Learners (ELL). The paper provides the basis for practical guidelines for the grouping practices in mathematics.

Computer Access and Computer Use for Science Performance of Racial and Linguistic Minority Students

This study examined the effects of computer access and computer use on the science achievement of elementary school students, with focused attention on the effects for racial and linguistic minority students. The study used the Early Childhood Longitudinal Study (ECLS-K) database and conducted statistical analyses with proper weights and design-effect adjustments. After controlling for age, gender, prior science performance, and family socioeconomic level, the effects of computer access and computer use on English Language Learners (ELL) and on English-speaking students were examined and compared by subdividing the participants into four racial groups: Caucasian, African American, Hispanic, and Asian. The results revealed that access to home computers and purposeful computer use had positive effects on the science performance of English-speaking students. In contrast, mere frequent computer use by English-speaking students yielded negative effects. Home computer access for ELL students indicated negative effects, especially for Hispanic ELL students. Frequent computer use also indicated negative effects for African-American and Hispanic English-speaking students, and for Asian ELL students. These results enhance our understanding of computer use in regard to science learning, and provide implications for future practice.

Academic Performance of Language-Minority Students and All-Day Kindergarten: A Longitudinal Study.

This longitudinal study examined the effect of all-day kindergarten programs on the academic achievement of students from racial language minority and low socioeconomic class. The study employed a series of 3-level longitudinal multilevel analyses using a nationally representative database, the Early Childhood Longitudinal Study (ECLS). The study showed that Hispanic dual-language-speaking students who attended all-day kindergarten narrowed the achievement gap from Hispanic English-only students during kindergarten. The results also showed that Black and Asian dual-language-speaking students, when they attended all-day kindergarten, displayed a significant gain in the growth of performances. The positive effects of all-day kindergarten were pronounced for Black and Asian language-minority students who were from low social classes. These results have implications for policy decisions and support the need for all-day programs for language-minority students.

Differential effects of learning games on mathematics proficiency

This study examined the effects of a learning game, [The Math App] on the mathematics proficiency of middle school students. For the study, researchers recruited 306 students, Grades 6–8, from two schools in rural southwest Virginia. Over a nine-week period, [The Math App] was deployed as an intervention for investigation. Students were assigned to game intervention treatment, and paper-and-pencil control conditions. For the game intervention condition, students learned fractions concepts by playing [The Math App]. In the analysis, students’ mathematical proficiency levels prior to the intervention were taken into account. Results indicate that students in the game intervention group showed higher mathematics proficiency than those in the paper-and-pencil group. Particularly, the significantly higher performances of intervention groups were noted among 7th graders and inclusion groups. The empirically derived results of the reported study could contribute to the field of educational video game research, which has not reached a consensus on the effects of games on students’ mathematics performance in classroom settings.

The effects of an educational video game on mathematical engagement

In an effort to maximizing success in mathematics, our research team implemented an educational video game in fifth grade mathematics classrooms in five schools in the Eastern US. The educational game was developed by our multi-disciplinary research team to achieve a hypothetical learning trajectory of mathematical thinking of 5th grade students. In this study, we examined overall engagement and three sub-domains of engagement as outcome variables after ten sessions of treatment with fifth grade students. The results showed that both male and female the video game group had slight increases in all engagement levels while students, particularly male, in the paper-and-pencil drill group displayed large decreases in all engagement levels. Implications of the study are 1) more fine-grained evidence of engagement in three sub-domains after implementing an educational video game, and 2) a consideration of gender differences in engagement levels in mathematics in the adoption of a video games.
