Authors: Jupri A , Sispiyati R
Published: March 2021

Symbol sense, an analogy of number sense in the symbolic world of mathematics, is an ability to give meaning to symbols, expressions, and formulas that involves many characteristics, including friendliness with symbols, an ability to examine symbol meanings, and skills to manipulate symbolic expressions. The characteristics of symbol sense are usually used, for instance, for designing symbolic algebra tasks, but are a bit rare for designing mathematics tasks in general. Therefore, this study aims to use symbol sense characteristics for designing mathematics tasks for secondary school students. To do this, using a design research method, we conducted a literature study to collect characteristics of symbol sense and to see possibilities of designing mathematics tasks in general. Next, we designed mathematics tasks according to the symbol sense characteristics. Finally, we provided possible responses of students for the designed tasks. The results of this study included six types of tasks according to the characteristics of symbol sense, including tasks on symbolic problems and word problems—which require translation into symbolic problems. In addition, we provided predicted responses to examples for each type of the tasks and suggestions for use in the learning and teaching process. For further investigation, we recommend to use the set of designed tasks for assessing student symbol sense ability.

Authors: Handayani A D , Yulianto D , Yohanie D D , Samijo  , Darsono
Published: March 2021

Cognitive development that must be considered in kindergarten is the ability to count which includes the concepts of addition and subtraction. Abstract mathematical concepts are not always well received by kindergarten students. Therefore, to support optimal child development, appropriate stimulants are needed. Some kindergarten students experience still have difficulties in summing numbers abstractly. There are also those who have difficulty in the counting process, both outlining and adding up. In addition, there are also students who are less able to write the large number of objects into numerical symbols. Given the various difficulties that can be experienced by kindergarten students in learning the concepts of addition and subtraction, one way that can be used to introduce the concepts of addition and subtraction in kindergarten students is by using the Iceberg approach. Iceberg is known as an iceberg phenomenon. The process of forming icebergs in the sea always starts from the bottom beneath the surface of the sea and so on finally forms the tip of the iceberg that appears above sea level. The base of the iceberg is wider than its peak, thus the construction of the iceberg becomes sturdy and stable. Introducing a mathematical concept based on the Iceberg approach means that in the iceberg model there are four levels of activity, namely: 1) mathematical orientation of the environment, 2) Model of teaching aids, 3) making of foundations (Building stone), and 4) formal mathematics. With this step it is hoped that kindergarten students who are still in the pre-operational stage can more easily understand abstract mathematical concepts because the concept begins with the introduction of concrete objects around students. The purpose of this study is to developing mathematics activity books based on the Iceberg theory to introduce the concepts of addition and subtraction for kindergarten.

One of the abilities that must be developed in 21st century learning is think creatively. The ability to think creatively is part of creativity that involves developing ideas and products the problems solve. This study aims to analyze the creative thinking skills of vocational students on waste treatment materials by applying project-based learning (PjBL). The study used weak experimental method by using one group pretest-posttest design. The subject of study was grade 10th students at one private high school in Cianjur. Data collection of students’ creative thinking used essay test. Essay test of creative thinking ability consists of five indicators namely (1) fluency, (2) flexibility, (3) originality, (4) elaboration, and (5) sensitivity to problem. The result shows that the highest gain score was fluency, with gain score of 12 and the lowest gain score obtained by sensitivity to problem with gain score of 5. The effectiveness of PjBL was seen from index N-gain with a medium category (0.40). The finding revealed that PjBL is quite influential in improving the students creative thinking abilities, especially in contextual teaching material such as waste management learning.
