Let function $f : V(G)longrightarrow {0, 2,..., 2k_v}$ as vertex labeling and a function $f: E(G)longrightarrow {1, 2,..., k_e}$ as edge labeling where $k=max{2k_v,k_e}$ for $k_v,k_e$ are natural number. The weight of vertex $ u,vin V(G) $ under $f$ is $w(u)=f(u)+ Sigma_{uv in E(G)} f(uv)$. In other words, the function $f$ is called local vertex irregular reflexive labeling if every two adjacent vertices has distinct weight and weight of a vertex is defined as the sum of the labels of vertex and the labels of all edges incident this vertex When we assign each vertex of $G$ with a color of the vertex weight $w(uv)$, thus we say the graph G admits a local vertex irregular reflexive coloring. The minimum number of colors produced from local vertex irregular reflexive coloring of graph $G$ is reflexive local irregular chromatic number denoted by $chi_{lrvs}(G).$ Furthermore, the minimum $k$ required such that $chi_{lrvs}(G)=chi(G)$ is called a local reflexive vertex color strength, denoted by emph{lrvcs}$(G)$. In this paper, we learn about the local vertex irregular reflexive coloring and obtain emph{lrvcs}$(G)$ of wheel related graphs.","PeriodicalId":305608,"journal":{"name":"CGANT JOURNAL OF MATHEMATICS AND APPLICATIONS","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122210245","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}

Metaliteracy is a comprehensive framework of thinking that goes beyond other literacies with the main literacy being information literacy. It is indicated that the metaliteracy of students is still low, it is because this literacy is still relatively new. The use of the IoT in learning is also still uneven, including the learning model used by teachers has not been able to fully support the formation of this ability. Therefore, in this study, the Research-Based Learning model which is integrated with the STEM approach (Science, Technology, Engineering, Mathematics) will be applied to solve the STEM problem of flight scheduling. Students are introduced to the application in the form of a set of sequential pairs, then with the representation of the set of points and lines a specific schedule is drawn up and includes its generalizations. The next step is how to bring STEM problem solving in learning class, then the developed RBL and STEM tools in learning to improve students' metaliteracy. From the results of the study, it was found that the RBL device with the STEM approach developed met the valid, effective, and practice criteria.","PeriodicalId":305608,"journal":{"name":"CGANT JOURNAL OF MATHEMATICS AND APPLICATIONS","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128424541","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}

One of its uses is as a tool in the learning process. Technology-based learning can make learning more interesting, effective and efficient, so that students are more enthusiastic about learning and easy to understand the material presented. The model used is the Thiagarajan or 4-D model which consists of four stages, namely the define, design, develop, and dissenimante stages. There are three data collection techniques carried out in this study, namely validity, obtained through validation by the validator; practicality, obtained from media user response questionnaires by students; effectiveness, obtained through the results of student learning tests after using the media. The results showed that the correlation coefficient with a valid interpretation was very high at 0.94. The results of the media user response questionnaire with a percentage of 88.25%. The results of the learning test with a percentage of completeness reaching 85.18% indicate that the learning media can be categorized as effective.
