In this context, the STEM (Science, Technology, Engineering and Mathematics) approach goes beyond the teaching of school subjects, and the teaching-learning of mathematics should allow learners to appropriate skills of problem solving and solution finding in different life situations. In fact, solving mathematical problems generates cognitive, metacognitive, affective and emotional processes. Therefore, the visualization of these processes allows teachers to implement adequate pedagogical strategies aimed at the development of learners' abilities and skills to solve mathematical problems. In the context of a digital pedagogy, its allowing the designers of computer systems to model the processes in order to set up intelligent tutorial systems (expert systems) helps in the development of mathematical problem solving skills. We present in this article a methodological and analytical approach allowing to verbalize, visualize the networks of resolution of mathematical problem and to represent them schematically. We conclude with a modeling of these networks.","PeriodicalId":20848,"journal":{"name":"RA JOURNAL OF APPLIED RESEARCH","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80648419","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The importance of a faculty member in educational institutions' productivity cannot be overstated. To provide a high-quality service, they must be mentally and physically fit. The role of a faculty is very significant for the productivity of educational institutions. The majority of academics are women. As a result, it's crucial to observe how these women manage their job and personal lives. In this context, the paper analyses the work life balance challenges faced by women faculty working in HEIs and impact of work life balance on women faculties’ performance in HEIs by using primary data. Through a literature analysis, the study chose three important factors that were appropriate for the study scenario. Workload, social support, and childcare were chosen as independent variables, whereas work life balance was chosen as the dependent variable. The primary data was collected via a standardized questionnaire by the researchers. In this article, a survey of 35 Bangalore educational institutions is undertaken using a sample of 220 instructors to determine the true state of work-life balance. The study finds that the work-life balance situation for female faculty members is moderate, which can be improved by providing flexible working hours, transportation, residential facilities, child care centers, flexible work arrangements/job sharing, reduced working hours and workload, and child schooling. The result of the research will be helpful for the HEIs administrators, to identify the importance of work life balance of female faculty in order to improve the outcome of their institutions.","PeriodicalId":20848,"journal":{"name":"RA JOURNAL OF APPLIED RESEARCH","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81267005","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The research explored gaps in knowledge regarding this theory as a contribution to knowledge, and in this instance the AHEI was the sample and epicentre of the research and was expected to meet foremost the needs of industry and government as employers of graduated students, then the needs of students and society in knowledge and innovation. This research was conceptual research using literature review only. A Pain Point or constraint is anything that prevents the system from achieving its goal like poor funding, high teaching loads, unattractive research prizes and incentives, low salaries that drive away talented academics and others and finally poor resourcing. The main reasons giving rise to this research were the facts that some colleges and universities in Africa faced challenges in graduate employability and suitability for industry and funding and needed accreditation by government agencies, and some had low innovation and research output. The main objective of this research was to contribute to theory building in the Theory of Higher Education and PPT and identify critical success factors for efficiency in service delivery excellence to students, industry and society in line with market orientation philosophy. The secondary objective was employability of graduates as the end product, maximising knowledge creation and innovation. Qualitative research method in the form of conceptual research was used in this research. The main findings were low salaries were driving away academics to NICs and overseas developed countries, lack of practicals/diverse teaching methods, lack of compulsory internship, unfair assessment, balancing classes with free time, the need for diversity in terms of faculty, uncommitted students, incompetent faculty, outdated syllabus, students from high schools not being college ready, graduates not matching industry requirements, poor internet service, low knowledge creation, lower levels of innovation and industrialisation in Africa, unattractive prizes for researchers and same for research incentives, lack of apprenticeship in some countries and no research funding.","PeriodicalId":20848,"journal":{"name":"RA JOURNAL OF APPLIED RESEARCH","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84269828","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
