Introduction
Education is one of the basic needs of every human being to support their life.Meanwhile, mathematics is one of the subjects that play an important role in education because mathematics is considered a basic science that is taught at every level of education.The function of mathematics is to organize and improve students' reasoning acuity so that it can clarify problem-solving in daily life, train the ability to communicate using numbers and symbols, train students to be truth-oriented by developing logical, critical, creative, objective, rational attitudes, careful, disciplined and able to work together effectively, and train students to always think regularly, systematically and structurally in a clear conception (Jufri, 2015).
There are five competencies in learning mathematics (NCTM, 2000): mathematical problem-solving, mathematical communication, mathematical reasoning, mathematical connection, and mathematical representation.The combination of these five competencies is called mathematical literacy skills that can help students solve problems in everyday life.The Organization for Economic Cooperation and Development (OECD) is an organization that conducts research related to the Programme International of Student Assessment (PISA) which includes mathematical literacy, reading literacy, and scientific literacy.Mathematical literacy can be defined as an individual's ability to formulate, use, and interpret mathematics in various contexts, including mathematical reasoning and using mathematical concepts, procedures, facts, and mathematical tools to describe, explain and predict phenomena (OECD, 2016).
Unnes J. Math.Educ. 2020, Vol. 9, No. 3, 236-242 In fact, Indonesian students' mathematical literacy skills are still low.Judging from the academic quality between nations through the Program for International Student Assessment (PISA) in mathematics in 2018, Indonesian students are ranked 72 out of 78 participating countries with a score of 379 from the OECD average score of 500 (OECD, 2019).The results of the PISA study (Wahyuni, 2009: 180) also show that 25% -34% of Indonesian students enter the literacy level-1.Whereas for the literacy level-5, less than 1% of Indonesian students are at this level.This means that only a few students have the ability to find complex information, demonstrate detailed understanding, draw conclusions, evaluate critically, build hypotheses, and put forward concepts.This shows that the ability of Indonesian students to solve problems in the form of study questions, give reasons, communicate, and solve and interpret various problems is still very low.
There are four contents of knowledge in mathematical literacy according to PISA 2015 (OECD, 2017) including (1) change and relationship, (2) space and shape, (3) quantity, (4) Uncertainty and data.Mathematical literacy refers to three processes called mathematical processes, these three processes include (1) formulating situations mathematically (identifying, translating, and formulating real problems into mathematical forms), (2) employing mathematical concepts, facts, procedures, and reasoning (applying concepts, facts, procedures and mathematical reasoning to solve problems), (3) Interpreting, applying, and evaluating mathematical outcomes (reflecting on solutions, results, or conclusions and interpreting them in context).According to PISA 2015, there are seven basic math skills (OECD, 2017), including communicating, mathematizing, representation, reasoning and argument, devising strategies for solving problems, using symbolic, formal and technical language and operations, and using mathematical tools.While the context used in the assessment is (1) personal, (2) occupational, (3) societal, (4) scientific.
The ability of students to apply mathematical concepts to daily problems better and effectively is related to mathematical literacy skills (Sari, 2018).Therefore, solving real problems becomes an important component in mathematical literacy where students formulate and implement strategies to solve problems that include components of mathematical literacy, namely devising strategies for solving problems.To improve mathematical literacy skills, a teacher must be able to select and apply an appropriate learning model.Research shows that the TAPPS learning model can improve problemsolving skills (Mashuri et al, 2018).Besides, students' communication skills are an important component of mathematical literacy (Wardono et al, 2020).Improved communication skills and mathematical reasoning skills with TAPPS learning are better than ordinary learning (Rosyana & Sari, 2015).
The TAPPS learning model requires two students who act as problem solvers and listeners to work together in solving problems by following certain rules.The TAPPS learning model is effective for optimizing problem-solving skills because when the problem solver reads the problem to listeners, students can optimize their problem-solving abilities directly to understand the problem.Furthermore, when the problem solver begins to explain problem-solving steps, students can optimize their problemsolving abilities at the stage of designing and implementing a plan.The previous phase will be optimal when the listener does their job, which is to correct the actions taken by the problem solver on its completion so that students can optimize their problem-solving abilities (Winarti et al, 2019).
To optimize the TAPPS learning model, a metaphorical thinking approach can be used.The metaphorical thinking approach is relevant to the objectives of learning mathematics.Metaphorical thinking is a thinking concept that emphasizes the relationship between mathematics and real phenomena.In mathematics learning, metaphors are used to connect mathematical concepts with concepts that are familiar to students in everyday life (Roesdiana, 2016).The concept of metaphoric thinking based on the structure and ways of reasoning according to the sensory-motory system is called conceptual metaphors (Hendriana 2012) which includes (1) grounding metaphors is understanding mathematical ideas and relating them to everyday experiences, (2) linking metaphors are building the relationship between the two topics, (3) redefinitional metaphors are redefining metaphors according to the topic being studied.According to Watson (Wijayanti, 2016), one of the creative teaching strategies is to use technology media that is following the development of the students' era.In this study, the Class Dojo media was used to help students' learning process.
Based on the background of the problems described above, the purpose of this study was to determine the description of students 'mathematical literacy skills after being taught using the TAPPS learning Unnes J.
