How Important of Students' Literacy and Numeracy Skills in Facing 21st-Century Challenges: A Systematic Literature Review

Literacy Numeracy skills (LNS) are fundamental for facing global challenges in the 21st century. LNS can help people achieve their goals. However, there has not been a thorough study on literacy and numeracy research. To improve the quality of literacy and numeracy research, researchers must study much literature for further analysis. This research aims to analyze students' literacy and numeracy skills in facing 21st-century challenges. The research method used is the Systematic Literature Review to read 27 documents by searching for the keywords "literacy", "numeracy", and “Literacy and Numeracy”. This type of research is library research with the stages of determining research questions, searching literature, selecting articles, reading full papers, making abstractions, and conducting analysis. The data analysis technique used is content analysis. The study results show that the dominant research methodology used is quantitative; the instruments often used are tests and assessments. The chief field is mathematics; the overall educational level is junior high school and early childhood education. Some motivational results research related to literacy and numeracy skills includes digital competencies, learning videos, and games, effectively improving literacy and numeracy skills. Furthermore, not all learners have strong reading and numeracy abilities. A strong recommendation for further research is to develop learning media based on local wisdom using the Android platform. In addition, researchers must embed emergent literacy in the design and case study of didactically and pedagogically oriented research.

College student interest in personal finance education

This study investigates demand for investing in financial literacy while in college using survey responses from a cross-section of students at a medium-size, private university. Results indicate that student interest in personal finance education is largely a function of perceived return, time cost, financial independence, and gender where female students have relatively more interest. Income, patience in consumption, credit experience, numerical ability, and other factors are not consistently significant to demand. The results support offering learning opportunities for individual personal finance topics in addition to a personal finance course.

Numerical cognitive reflection, but not verbal cognitive reflection, moderates the association between trait anxiety and affective decision‐making

AbstractAffective decision‐making is a decision process with significant and strong emotional consequences marked by meaningful rewards and losses. Previous studies found inconsistent results regarding whether trait anxiety hinders affective decision‐making. Also, previous studies also proved that people with lower cognitive reflection were less likely to exhibit better performance in decision‐making when compared with higher cognition reflection individuals. Using the risk‐as‐feeling hypothesis, which explicitly postulates an interaction between cognitive and affective processes in people's decision‐making, we explore whether cognitive reflection moderates the relationship between trait anxiety and affective decision‐making. Participants (N = 261) completed the standardized version of the Iowa Gambling Task, which is widely used to assess affective decision‐making, Trait Anxiety Inventory, numerical cognitive reflection test (numerical CRT), and verbal cognitive reflection test (CRT‐V). The results showed that cognitive reflection measured by the numerical CRT rather than the CRT‐V moderated the relationship between trait anxiety and affective decision‐making. Specifically, individuals with lower cognitive reflection exhibited a negative association between trait anxiety and affective decision‐making, whereas individuals with higher cognitive reflection did not exhibit a relationship between trait anxiety and cognitive reflection. The present study helps to explain how cognitive reflection and trait anxiety interact in affective decision‐making and provides guidance targeting individuals with higher trait anxiety to improve their numerical cognitive reflection ability and better address their affective decision‐making.

Effectiveness of Using the Congklak Game in Improving the Numeracy Skills of Grade 1 Elementary School/MI Students

One unique component that contributes to an individual’s intellect is their capacity for calculation. The Congklak game is one of the most useful educational tools for helping primary school pupils improve their numeracy abilities. An ancient game that continues to rise in popularity in Indonesian society is congklak. This kind of research uses experimental methodologies and is quantitative in nature. Pre Experimental Designs is the design that was employed in this study. One Group Pretest-Posttest Design is the type of pre-experimental design that is employed. A significant value (p) of 0.000 < 0.05 was found for the Paired Sample T-Test analysis, yielding a value of t = -11.730. This demonstrates that class I students at SDN 22 Bilah Hulu had a different average numeracy ability before and after receiving learning materials in the form of the classic game congklak. After receiving learning materials in the style of the classic Congklak game, students’ average numeracy skill is higher than it was prior to receiving the conventional Congklak game learning materials. This study demonstrates the efficacy of the classic Congklak game learning resource in raising primary school students’ numeracy proficiency.

The correlation of numerical ability with learning outcomes in mathematics economics of management students of the Universitas Sumatera Barat

This research is motivated by the fact that not all students can do math calculations well. This can be seen when students carry out exercises on matrix material and the application of linear functions in economics that require numerical skills, namely the addition and subtraction of integers. There are still many students who are confused in doing the exercise, especially with quite large numbers such as tens and hundreds. At the time of doing the distribution of many students who hesitate in doing it. Likewise with multiplication, there are even some students who have not memorized multiplication from 1 to 10. From this the researcher concludes that not all students have good numerical skills, so that students in working on math problems tend to experience difficulties and cause students' low economic mathematics learning outcomes. The average student learning outcomes are still below the minimum standard, in this case it can be seen from the midterm exam scores in mathematics economics management students at the Faculty of Economics, Universitas Sumatera Barat. So, one of the factors that influence students' learning outcomes in economics mathematics is numerical ability. This type of research is ex post facto correlational research, namely research that is intended to determine whether there is a relationship between two or several variables. The population in this study were all management students at the Faculty of Economics, Universitas Sumatera Barat, who took four classes of economics mathematics, consisting of 128 students. The instruments used in this study were numerical ability tests and learning achievement tests. The analysis used in this research is linear correlation analysis. The results showed that there was a significant relationship between numerical ability and the learning outcomes of economic mathematics students at the Faculty of Economics, Universitas Sumatera Barat. This is also seen from the value of the correlation coefficient , the correlation coefficient when seen in the table of the level of closeness of the relationship between X and Y variables, then the level of closeness of the relationship is in the medium relationship category because it is in the range. So, it can be concluded that there is a significant relationship between numerical ability and the results of learning economics mathematics from students of management at the Faculty of Economics, Universitas Sumatera Barat.

Are they equivalent? An examination of task variants of approximate number comparison.

Nonverbal numerical ability supports individuals' numerical information processing in everyday life and is also correlated with their learning of mathematics. This ability is typically measured with an approximate number comparison paradigm, in which participants are presented with two sets of objects and instructed to choose the numerically larger set. This paradigm has multiple task variants, where the two sets are presented in different ways (e.g., two sets are presented either simultaneously or sequentially, or two sets are presented either intermixed or separately). Despite the fact that different task variants have often been used interchangeably, it remains unclear whether these variants measure the same aspects of nonverbal numerical ability. Using a latent variable modeling approach with 270 participants (Mage = 20.75 years, SDage = 2.03, 94 males), this study examined the degree to which three commonly used task variants tapped into the same construct. The results showed that a bi-factor model corresponding to the hypothesis that task variants had both commonalities and uniqueness was a better fit for the data than a single-factor model, corresponding to the hypothesis that task variants were construct equivalent. These findings suggested that task variants of approximate number comparison did not measure the same construct and cannot be used interchangeably. This study also quantified the extent to which general cognitive abilities were involved in both common and unique parts of these task variants.

Communicating scientific uncertainties

Abstract. Communicating a message of scientific uncertainty to a general audience is difficult because laypeople usually lack the conceptual tools to understand uncertainty (e.g., quantification methods). In addition, uncertainties can lead to mistrust and can be misused to prevent or delay radioactive waste management. On the proposed poster, we report the results of an experimental study (N=177) that investigated preferences for and trust in different visualizations of simulation results and tested different modes of communication (verbal, numerical, and visual/graphical). The participants processed three different parts, namely (1) the variation in the form of presentation of a scientific result, (2) the variation in the sender/source of a scientific result in numerical format, and (3) a direct comparison of two representations of simulation results (deterministic and probabilistic). Besides socio-demographics, we used items to check for the potential impact of numeracy and verbal skills, the need for a cognition concept, and questions on science in general, as well as the acceptance of a potential deep-ground repository. The dependent variable in each part was the degree of trust in the scientific validity of the information. For an example result, see Fig. 1. Clear influences of the non-dependent variables are only evident to a limited extent. Women rate their numerical abilities less highly than men do. There is no difference in verbal skills. The latter variable is also not explanatory, while numerical ability is relevant for the choice of the probabilistic variant and the corresponding trust rating in Experiment 3. The most striking result is that the attitude towards a deep geological repository for high-level nuclear waste (HLW; degree of acceptance) is the decisive parameter in all experimental conditions. The oral presentation will focus on another challenge of uncertainty communication, namely unquantifiable model uncertainties. In a repository, these may arise from the heterogeneity of the host rock. One of these potential uncertainties may be an undetected fault parallel in the drift axis in clayey host rocks. At the Konrad site, an anchor failure in an infrastructure drift resulted from such a fault. To deal with this kind of uncertainty, a certain kind of flexibility is needed to react to such events. The talk should initiate a discussion on the importance of communicating these potential uncertainties and on the impact of these uncertainties on the repository program.
