Exhaustive geological fieldwork reveals Ado-Ekiti is underlain by migmatite-gneiss, quartzite, granite (porphyritic and fine-grained) and charnockite. Petrographic investigation revealed overwhelming presence of quartz, biotite and plagioclase in all the rocks while microcline and opaque minerals occur in subordinate amounts. Average SiO2 content in porphyritic granite (74.56 %) is marginally higher than charnockite (73.51%) and fine-grained granite (70.41%). These values correlate well with previous works in the study area and agrees with similar rocks in other parts of the country. Analytical results using Phillips Panalytical PW1480 X-ray Fluorescence Spectrometer with Rhodium Tube as the X-ray source revealed the siliceous nature of the rocks. The binary plot (Na2O+K2O) vs SiO2 established the rocks are granitic with all the samples plotting within granite field. AFM ternary diagram shows the rock have calc-alkaline affinity. Geochemical classification by (Na2O + K2O-CaO) vs SiO2 diagram reveals the rocks are “Calc-alkalic and calcic”. The elevated K2O (average of 4.41%) in the data signaled High-K calc-alkaline type on K2O vs SiO2 binary diagram. Alumina Saturation Index (ASI) showed the rocks are metaluminous while Al2O3 / (Na2O + K2O) vs Al2O3/ (Na2O +K2O +CaO) plot suggest the rocks have mantle origin","PeriodicalId":13763,"journal":{"name":"International Journal of Applied Science and Engineering Research","volume":"14 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89650148","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 interconnection of these four levels makes a major contribution to the development of students' mental models in building the meaning and conceptual understanding of biological materials. Mental models are ideas in the minds of students that are used to develop, explain, and predict a phenomenon. The formation of mental models is influenced by the experiences they have, their confidence or selfefficacy, and the problems they face. Multiple representations are believed to influence the formation of mental models and students' self-efficacy. For this reason, an in-depth study of the role of multiple representations in building mental models and students' self-efficacy is needed. This research is qualitative research with descriptive analysis techniques and a literature review (library research). The analysis is carried out by reviewing articles that are relevant to the study being discussed. In the search for articles, four keywords were used, namely: multiple representation learning, biology learning, mental models, and self-efficacy. The articles used in this study were 25 international articles obtained from Google Scholar and ERIC. From the results of the study, it was found that learning multiple representations is very effective in building mental models and self-efficacy in biology students. From the results of this study, it is recommended for lecturers and teachers to use multiple representations learning in the learning process to build mental models and self-efficacy in students.","PeriodicalId":13763,"journal":{"name":"International Journal of Applied Science and Engineering Research","volume":"81 5-7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91471303","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}

Competence based curriculum digital literacy emphasizes development of digital skills, knowledge and core competences in learners’ real life situation, in Kenya. However, competence-based curriculum implementation is insufficiently managed following limited digital technology use in schools; rising concern on effectiveness of competence based learning activities in Kenyan schools. The objective of the study is to determine relationship between competence-based digital literacy concepts and management of primary school curriculum implementation in Embu County, Kenya. The study involved 364 respondents using purposive and simple random techniques. The study employed correlation research design. The study respondents were: competence-based classroom teachers, subject panel heads, senior teachers, head teachers and deputy head teachers. The data collection tools were questionnaires and interview guides for head teachers, deputy head teachers, subject panel heads, senior teachers and competence based classroom teachers. The descriptive statistics was presented in frequencies and percentages; while inferential statistics was analyzed using regression statistic technique. The study reviewed that most school managers have integrated in teaching and learning the current and emerging digital technologies to support curriculum delivery and management; as well as managing and creating information in the immediate digital environment. The study established that digital technologies enable provision of individualized learning management system for teachers. The study indicated that there is significant relationship between competence-based digital literacy concepts and management of primary school curriculum implementation in Embu County, Kenya. Following study findings, the researcher concludes that competence-based digital literacy concepts are crucial in management of primary school curriculum implementation in Kenyan schools. Therefore, the researcher recommends that ministry of education should promote digital literacy technologies for efficient curriculum implementation management in primary schools in Kenya.","PeriodicalId":13763,"journal":{"name":"International Journal of Applied Science and Engineering Research","volume":"39 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81315306","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}
