This study investigates students’ quantitative reasoning in STEM and Non-STEM math pathways using a non-proprietary, NSF grant-funded instrument, the Quantitative Literacy & Reasoning Assessment (QLRA). Participants were students enrolled in at least one college-level math pathway course at a large public institution in the southeastern US. The results showed a significant difference between STEM and Non-STEM students’ QLRA scores, with STEM students (n = 244, M = 27%, SD = 16.21%) scoring, on average, about 6% higher than Non-STEM students (n = 295, M = 21.1%, SD =11.38%). STEM students who were further along in their math sequence, i.e. Pre-calculus/Trigonometry and Calculus I, had a higher QLRA score than those taking the gateway math courses in that pathway. Non-STEM students who took additional math courses also had a higher QLRA score than those in the entry-level math course. However, the students overall had relatively low QR skills (n = 539, M = 23.78%, SD = 14.07%). These results highlight the need for an increased understanding of the math pathways initiative and its relationship with quantitative reasoning. Thoughtful and deliberate scrutiny of curriculum and pedagogy is important in all math pathways as it relates to the development of quantitative reasoning skills.","PeriodicalId":36166,"journal":{"name":"Numeracy","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43997525","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}

Students are still difficult to draw conclusions, understand problems, and provide reasons for the answers produced. One way to develop students' ability to solve problem solving problems is to get students to develop questions. When students make questions it is expected to understand the questions well. The strategy that can be used to familiarize students with developing questions is through the Problem Posing approach. The purpose of this study is to analyze the students' ability to develop problem solving questions. This study uses a qualitative approach with descriptive types. The subjects of this study were six students at Junior High School 3 Banda Aceh. Students 'ability in compiling problem solving questions is analyzed by categorizing the students' questions based on the type of difficulties that are seen from the structure of the language and the structure of mathematics. The results showed that students who meet the indicators understand the problem, make plans, carry out plans and check again, are able to make problems in terms of mathematical structures containing propositions to change, restate and vary, in terms of language structures containing presuppositions. Furthermore, students who meet the indicators understand the problem, make plans and implement plans, make the problems in terms of the mathematical structure containing propositions grouping and varying, in terms of the structure of the language containing the assignment propositions.
