This study investigated senior secondary school students’ understanding of and attitudes toward nanotechnology-enhanced green materials and sustainability, with a focus on their exposure to artificial intelligence (AI)-driven service-learning experiences. Anchored in a descriptive survey research design, the study targeted 232 students from three purposefully selected ICT-equipped schools in the Nsukka Education Zone of Enugu State, Nigeria. These schools were chosen for their access to AI-based learning platforms and the integration of environmental education topics across relevant subjects. Data were collected via the Students’ Knowledge and Attitudes toward Nanotechnology-Enhanced Green Materials and Sustainability Questionnaire (SKANSQ), which was developed through a literature review and expert validation. The instrument demonstrated high reliability, with a Cronbach’s alpha coefficient of 0.83. The questionnaire measured students’ knowledge, attitudes, exposure to AI tools and service-learning activities, and perceptions of how these experiences influenced their understanding of sustainability concepts. Descriptive statistics, means and standard deviations, were employed to address the research questions. The findings revealed that while students reported a moderate level of knowledge and demonstrated generally positive attitudes toward sustainability and green innovations, their actual exposure to AI-supported learning and community-based service-learning projects was relatively low. The results suggest a gap between curricular intentions and the practical implementation of experiential and technology-enhanced learning strategies. This study underscores the need for schools and policymakers to promote more deliberate integration of AI tools and service learning into science and environmental education to better prepare students for global sustainability challenges.

Purpose: The purpose of this study was to identify if there were relative and combined influence of marital satisfaction, perceived organizational support on job involvement of employed women. Theoretical framework: Despite their demanding roles at home, employed women are expected to be at their best in the work-front. The study investigated the influence of marital satisfaction and perceived organizational support on job involvement among employed women.   Design/Methodology/Approach: Two hundred employed women from South-West Nigeria chosen through proportional stratified random sampling technique served as participants. The 5-item Job Involvement Questionnaire (JIQ), a 20-item Perceived Organizational Support Questionnaire (POSQ), and Enrich Marital Satisfaction Scale (EMSS) of 16 items were the instruments used. Three hypotheses were tested at .05 level of significance with multiple regression analysis and correlation matrices. Findings: Results showed that marital satisfaction and organizational support combined to influence job involvement (F_{(2, 197)} = 40.942, p < .05), organizational support (β = .202; t = 14.613; p < .05) and marital satisfaction (β = .134; t = 10.402; p < .05) had significant relative influence on job involvement, and there were significant positive bivariate relationships among the variables of the study. Research, Practical & Social implications: It was concluded that marital satisfaction is an important area of life for employed women and along with organizational support, could significantly impact job involvement. Originality/Value: Results revealed that relationships among marital satisfaction, perceived organizational support, and job involvement exist hence employees do have perceptions of organizations that may affect their attitudes, behaviours and performance.
