While appropriate for measuring student learning at the programmatic or institutional level, such instruments were not designed for classroom grading. After modifying a widely accepted institutional rubric designed to assess QR in written arguments, the current mixed method study tested the reliability of two QR analytic grading rubrics for written arguments and explored students’ reactions to the grading tools. Undergraduate students enrolled in a business course (N = 59) participated. A total of 415 QR artifacts from 40 students were assessed; an additional 19 students provided feedback about the grading tools. A new QR writing rubric included three main criteria (numerical evidence, conclusions, and writing), while a second rubric added a fourth criterion for assignments with data visualization. After two coders rated students’ QR assignments, data analysis found both new QR rubrics had good reliability. Cohen’s kappa found the study’s raters had substantial agreement on all rubric criteria (κ = 0.69 to 0.80). Both the QR writing (α = 0.861) and data visualization (α = 0.859) grading rubrics also had good internal consistency. When asked to provide feedback about the new grading tools, 89% of students shared positive comments, reporting the rubrics clarified assignment expectations, improved their performance, and facilitated the writing process. This paper proposes slight modifications to the phrasing of the new rubrics’ writing criterion, discusses best practices for use of rubrics in QR classrooms, and recommends future research.","PeriodicalId":36166,"journal":{"name":"Numeracy","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70471841","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}

I illustrate these issues with examples from an empirical study of the association between how much time teenagers spent playing video games and time spent reading. I describe how study design and context determine each of those aspects of “importance,” and close by summarizing how to provide a holistic view of importance when writing about a quantitative analysis.

This cognitive ability is one of the important skills in supporting students with mathematical concepts. However, the advantages of computational thinking do not seem to be paid much attention to by education, especially in Indonesia. This is because the learning approach does not emphasize the positive aspects that can improve students' computational thinking. As a result, the average computational thinking ability of students is low. This type of research uses an experimental method of pretest-posttest control group design. The population involved was class XII students at MA Daruttauhid Malang, which consisted of 22 students in the experimental class, and 24 students in the control class. The research data is in the form of pre-test scores before being given realistic mathematics learning treatment, and post-test score data. The results obtained showed that the computational thinking ability of students in the experimental class was higher than in the control class. To be clear, this fact is measured by calculating the N-Gain scores of students in the experimental class with a value of 0.7 (high category), and the N-Gain scores of control class students with a value of 0.5 (medium category). \u0000Abstrak \u0000Berpikir komputasional adalah jenis kemampuan pemecahan masalah menggunakan logika berpikir yang dilakukan siswa dengan langkah yang teratur.
