Younger and older participants were asked to indicate if 240 complex two-digit addition problems were smaller than 100 or not. Half of the problems were small-split problems (i.e., the proposed sums were 2% or 5% away from 100; e.g., 53 + 49) and half were large-split problems (i.e., proposed sums were 10% or 15% away from 100; 46 + 39). Behavioral and event-related potential (ERP) data revealed that (a) both groups showed a split effect on both reaction times and percent errors, (b) split effects were smaller for older than for younger adults in ERPs, and (c) the hemispheric asymmetry (left hemisphere advantage) reported for younger adults was reduced in older adults (age-related hemispheric asymmetry reduction). These results suggest that older adults tend to use only one strategy to solve all problems, whereas younger adults flexibly and adaptively use different strategies for small- and large-split problems. Implications of these findings for our understanding of age-related similarities and differences in arithmetic problem-solving are discussed.

Abstract Aging presents change in the form of opportunities and challenges, from common physical alterations, to major life events. Perception of such events is greatly shaped by one’s mental health, and is a major influence on gerotranscendence, a positive kind of aging involving redefinition of self, relationships, and proposed to be a precursor to successful aging. A mixed-methods cross-sectional descriptive design was used to study 50 older adults. Life Events Checklist, Gerotranscendence Scale, Herth Hope Index, and Successful Aging Inventory were administered. Mean participant age was 70.78 years; there were 9 males (18%), 41 females (82%), 13 were Black (26%), and 37 were White (74%). Participants reported a number of stressful events, most frequently transportation accidents, followed by other very stressful events or experiences, and sudden unexpected death of someone close. Gerotranscendence scores ranged from 0-10 (µ 6.88, a moderate score). Successful aging scores ranged from 40-79 (µ 62.33, a moderate score). A sub-sample of 6 participants engaged in semi-structured interviews, which were transcribed verbatim and subject to content analysis. Faith, displaced longing, temporal anticipation, proactive problem-solving/coping, and concern for future generations were emergent qualitative themes. Findings highlight opportunities for providers from multiple disciplines to target risks and possibilities for aging successfully and to promote hope, optimism, problem-solving skills, and gerotranscendence in all older adults, regardless of physical or functional health status.

Background: There is a need for interventions to promote health management of older adults with pre-frailty and frailty. Technology poses promising solutions, but questions exist about effective delivery. Objectives: We present the results of a mixed-methods pilot evaluation of Virtual Online Communities for Older Adults (VOCALE), an 8-week intervention conducted in the northwestern United States, in which participants shared health-related experiences and applied problem solving skills in a Facebook group. Methods: We performed a mixed-methods process evaluation, integrating quantitative and qualitative data, to characterize the intervention and its effects. We focus on four areas: health-related measures (health literacy and self-efficacy), participation, problem solving skills enacted, and subjective feedback. Results: Eight older adults with pre-frailty and frailty (age = 82.7 ± 6.6 years) completed the study. There was an upward trend in health literacy and health self-efficacy post-intervention. Participants posted at least two times per week. Content analysis of 210 posts showed participants were able to apply the problem solving skills taught, and exit interviews showed participants’ increased awareness of the need to manage health, and enjoyment in learning about others. Conclusion: This mixed-methods evaluation provides insight into feasibility and design considerations for online interventions to promote health management among vulnerable older adults.

This study aims to develop a mathematics handout based on local wisdom nuanced to increase the mathematical problem-solving skill of the Secondary students. This research is motivated by the student’s ability to solve the social arithmetic problem. This study used four phases of developmental research such as Investigation, Design, Realization, and Test, Evaluation, and Revision. The characteristics of local wisdom were acquired within the design or context in the mathematics handout to develop secondary students problem-solving skills. The results show that the students do the stages of problem-solving by Polya, get the maximum score and show students’ positive responses in the questionnaire given. Therefore, it met the proper handout criteria such as valid, practice, and effective. In the future studies, we encouraged to develop learning materials which have a guide to do phases of problem-solving and apply the way to solve some problems in mathematics.
