THE EFFECTIVENESS OF COOPERATIVE LEARNING METHOD TO REDUCING STUDENTS ANXIETY IN LEARNING MATH AT GRADE VII SMP NEGERI 1 BAUBAU

The problem of this research is whether the application of cooperative learning method is effective in reducing student’s anxiety in learning Math at grade VII at the topic of round numbers. The objective of the research is to know the effectiveness of cooperative learning in reducing student’s anxiety in learning Math at the topic of round numbers at grade VII SMP Negeri 1 Baubau. This research is descriptive quantitative by applying quasi experimental design. The sample taken consisted of 54 students which is each group consisted of 27 students. The instrument used in this research is test. The result of the research show that (1)The mean score of students learning in Math in experimental group before treatment is 56,48 with standard of deviation is 18,65 and after treatment is 83,70 with standard of deviation is 15,54. (2)The mean score of students learning in Math in control group before treatment is 56,67 with standard of deviation is 17,26 and after treatment is 73,51 with standard of deviation is 17,58. (3)Based on the mean score of students result in learning who is taught through those model of learning and seeing the result of statistic inferential of t test shows that learning through cooperative learning method is more effective to reduce students anxiety in learning Math.

When Falling Just Short is a Good Thing: The Effect of Past Performance on Improvement

Models of reference-dependent preferences show that an individual’s utility depends on the difference between the outcome and a “neutral” reference point. Our paper investigates how distance from reference points affects future performance. We find that round numbers and personal bests motivate runners and that missing the goal by a small amount improves future performance. For those who achieve their goal, future performance suffers slightly. In empirical analysis, we use an extensive panel of marathon data, which contains a past running history for every runner in our sample and allows us to estimate runners’ ability and experience.

Rhetorical uses of precise numbers and semi-magical round numbers in political discourse about COVID-19: Examples from the government of the United Kingdom

This paper examines how the British government has used statistics about COVID-19 for political ends. A distinction is made between precise and round numbers. Historically, using round numbers to estimate the spread of disease gave way in the 19th century to the sort precise, but not necessarily accurate, statistics that are now being used to record COVID-19. However, round numbers have continued to exert rhetorical, ‘semi-magical’ power by simultaneously conveying both quantity and quality. This is demonstrated in examples from the British government’s claims about COVID-19. The paper illustrates how senior members of the UK government use ‘good’ round numbers to frame their COVID-19 goals and to announce apparent achievements. These round numbers can provide political incentives to manipulate the production of precise number; again examples from the UK government are given.

Modeling response granularity with mixture models: A case of severity ratings in child maltreatment

Heaping, where responses are concentrated in round numbers, such as 5 or 10, is one of the response behaviors observed in surveys. The heaping phenomenon in subjective quantities may be explained by response granularity, which expresses the uncertainty of subjective quantities. We conducted an exploratory study using mixture models with a response granularity assumption, and used the severity ratings of child maltreatment measured by slider scales with numerical feedback as a case of heaped subjective quantity (14 401 records from 487 respondents). The results of the model comparison showed that it was reasonable to assume a response granularity for severity ratings. We classified the respondents into five groups based on the uncertainty of response granularity because individual differences were observed. This study proposes the usefulness of an approach that utilizes mixture models to examine individual response granularity.

Screen Personal Tool to Improve Students Understanding of The Concept Of Summing Round Numbers in SDN 1 Linggasari

<p><em>The background of the writer is the students' lack of understanding of the concept of adding make numbers.While the purpose of this study is to determine how much influence the use of number line props on student motivation. And to find out how much influence the number line props have on understanding of the teaching material.The method that I use is to use number line props on the concept of adding whole numbers. This research was conducted through a cycle assessment process consisting of four stages (planning, implementing, observing, and reflecting) in three cycles of learning improvement. From the results of the analysis, the conclusions obtained from this study are: 1) The use of number line props in the material of adding whole numbers can increase students' understanding by 71.79%, namely from the initial condition 28.21% to 100% in the third cycle. 2)The use of number line props on the sum of integers material can increase the seriousness of students by 74.36%, namely from the initial condition 25.64% to 100% in the third cycle. Conclusions from this study Is an effective use of number line props to improve understanding of integers.</em></p>

Towards simpler and more transparent quantitative research reports

The average quantitative research report in applied linguistics is needlessly complicated. Articles with over fifty hypothesis tests are no exception, but despite such an onslaught of numbers, the patterns in the data often remain opaque to readers well-versed in quantitative methods, not to mention to colleagues, students, and non-academics without years of experience in navigating results sections. I offer five suggestions for increasing both the transparency and the simplicity of quantitative research reports: (1) round numbers, (2) draw more graphs, (3) run and report fewer significance tests, (4) report simple rather than complex analyses when they yield essentially the same results, and (5) use online appendices liberally to document secondary analyses and share code and data.

Characteristics of Student Mental Models in Negative Round Numbers

The purpose of this study is to know, to describe, and to analyze students' mental model on negative integers. This research uses a descriptive qualitative approach. The data collection techniques use test, observation, interview, and documentation. The data analysis techniques use data reduction, data presentation, and conclusions. The result shows that there are three characteristics of students' metal model, the characteristics of early mental model on negative integers are only able to understand the minus sign as a count operation, students with formal mental model characteristics on negative integers understand the existence of negative numbers that have values ​​smaller than 0 but do not understand that numbers going left on the number line, it can be smaller values. Students with formal mental model characteristics on negative integers understand the direction on the number line and the value of each number correctly. It can be concluded that in understanding the scale of negative integer values ​​and negative integer places on number line, every student has different characteristics. The characteristics of the early mental model are the characteristics of the lowest mental model, the characteristics of the synthesis mental model are the characteristics of the moderate mental model and the characteristics of the formal mental model are the characteristics of the highest mental model in understanding negative integers.

Never too rich to care about prices: Effects of price endings on customer perceptions of luxury

In this article, we build on the existing literature on price endings in the fast-moving consumer goods and luxury pricing to highlight the potential paradox of adopting odd pricing (i.e. setting prices just below the round number) for luxury goods, which should mostly use even pricing (i.e. round numbers). In a first experiment concerning luxury handbags, we test the impact of three types of price endings (–90, –00, and “other”) on luxury image and its sub-facets. We propose four mediators of the relationship between price endings and overall luxury image, that is, quality, prestige, uniqueness, and expensiveness. In a second experiment, we find that price endings have connotations specific to the luxury sector and to different segments of consumers. We conclude with recommendations to help pricing managers strategically adjust their price-ending practice to target different consumer segments.
