However, specifically in this paper, the researcher reveals the other side of the development results of these learning tools, namely the development and obstacles faced by students in increasing higher-order thinking skills (Higher-Order-Thinking). Therefore, the specific objective of this study is to determine the development trend of students' higher order thinking skills and the difficulties encountered during learning. The research instruments were student on-task activity sheets, student activity observation sheets, formative tests and learning outcomes tests. The test was conducted on 66 students of class X SMAN 3 and SMAN 5 Banda Aceh as samples. The test results show that the mathematics learning device is valid, practical and effective in accordance with predetermined product criteria. The tendency for the development of high-order thinking skills (HOTS) of students in formative exercises (T1 and T2) moved up and the Learning Outcomes Test was good, on average 72%.

The research design was an experimental group with a pretest and posttest control group. The experimental group received geogebra-assisted contextual learning and the control group received conventional learning. To obtain research data, instruments used in the form of tests of creative thinking skills and students' self-concept attitude scale. The output in this research is in the form of learning tools (lesson plans and worksheets) that use geogebra-assisted contextual learning, instruments for tests of creative thinking abilities and students' self-concept scales. Quantitative analysis was carried out on normalized post-test and gain data on creative thinking skills and self-concept data between the two sample groups using the mean difference test of the two populations. The instrument used was 12 questions about creative thinking skills and 31 statements about self-concept. To find the difference in the average used t-test and use the Pearson test to find the correlation coefficient. The results showed that the creative thinking skills of students who received geogebra-assisted contextual learning were better than students who received conventional learning. The results of the self-concept scale indicate that the self-concept of students who receive geogebra-assisted contextual learning is better than the self-concept of students who receive conventional learning. The results of the self-concept scale also show that self-concept affects students' creative thinking abilities either totally or based on student groups, namely the experimental group and the control group. \u0000Abstrak \u0000Penelitian ini bertujuan untuk menelaah dan mendeskripsikan pengaruh pembelajaran kontekstual berbantuan Geogebra terhadap kemampuan berpikir kreatif, peningkatan kemampuan berpikir kreatif, self-concept siswa terhadap matematik dan hubungan berpikir kreatif dengan self-concept.

Models are developed here that consider the probability an individual will become infected as a function of: prevalence of the disease in the university community, number of students in class, number of class meetings, and transmission rate in the classroom given the presence of an infected individual. Absolute probabilities that an individual will become infected in a classroom environment cannot be calculated because some of these factors have unknown values. Nevertheless, models suggest that some strategies for minimizing probability of infection are more effective than others. Given that COVID-19 might be present among faculty and students in the university community, limiting class meetings and class size are not likely effective strategies unless these numbers are dramatically reduced. That is, it is likely that infected individuals will be present in classrooms at some point during the term due to the large number of interactions among university faculty and students. The probability of infection of an individual in a classroom setting appears to be most sensitive to the effectiveness of transmission in the classroom, given the presence of an infected individual, especially if the likelihood of transmission itself is a function of class size. If on-campus instruction takes place, efforts should focus on reducing the probability of transmission through physical modifications and upgrades to classrooms and by social distancing measures.","PeriodicalId":36166,"journal":{"name":"Numeracy","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46930427","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}

Such frameworks for conceptualizing numeracy pose a challenge to assessment because what individuals do with numeracy is not the same as what individuals can do (or express) in an assessment setting. This study builds on work related to numeracy assessment through a validity examination of a portion of a well-known assessment: the OECD’s Programme for the International Assessment of Adult Competencies (PIAAC). In following a path set out by standards for assessment, I ask: What does the PIAAC numeracy assessment claim to measure? What are the intended uses of the assessment? How are we to interpret scores with those uses in mind? And to what degree do evidence and theory support interpretations for those uses? The main finding from this work is that while score interpretations from the PIAAC numeracy assessment may be valid for the use of describing proficiency distributions for specific groups, the construct of interest—numerate behavior—is not what is measured. Moreover, evidence distinguishing what is measured from other constructs, such as the OECD’s conception of literacy, is largely absent. This study contributes to existing literature on numeracy assessment by providing sources of evidence to consider in making judgments about validity for an assessment. It also suggests that, as scholars, we carefully hedge the ways that we talk about large-scale assessments, and in relation, what individuals can or cannot do based on results from such assessments.","PeriodicalId":36166,"journal":{"name":"Numeracy","volume":"9 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70470794","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}
