“…They are typically stored using a fixed amount of memory, allowing for efficient storage and manipulation of large sets of integers. Integers are essential for performing arithmetic operations like addition, subtraction, multiplication, and division [3]. These operations are fundamental in computer programs and mathematical computations.…”

Big number operation has always been a bottleneck to computer system as it imposes high demand on computing power. With a limited power available, operations such as exponentiation and multiplication involving large integer belonging to encryption process requires grave scrutiny. One way to address this issue is by replacing an original complex computation into a sequence of small computations that in the end produces the same results. This paper takes an evolutionary approach to survey numerous articles that have contributed to the advancement of integer representation. Numerous representations were proposed, those that come into play concentrated on reducing non-zero digits and limiting non-zero spacing other than allowing subtraction operation. A comparison was made to distinguish the properties of each method from the others. This detailed outlook can be a guide for identifying the correct representation to be chosen for implementation within specific application.

“…PA subjects can use formulas obtained from the algorithm process from the beginning to the end through the abstraction stages. Abstraction is an essential element of computational thinking (Cetin, 2019). Solve step by step of each implemented problem requires abstraction to decide which data should be deleted and saved (Mgova, 2018) The subject describes the table and chair layout in the abstraction process to produce concrete and dynamic visualizations.…”

This research aimed to determine how the number pattern concept's computational thinking characteristic picture was reviewed from the Kolb model's learning style. The research method used in this study is qualitative descriptive. The research was conducted at one of the state's small schools in Bandung. The research subjects consisted of 29 students in the ninth grade. One of the 29 study issues is selected with assimilator learning styles. The data-gathering techniques used are questionnaire tests, test instruments, and interviews. Angket is used to group subjects into four groups of learning style types. The test instrument was used to describe the computational thinking characteristics of high school students on the concept of number patterns, and the interview was used to strengthen the test summary results of the subject. The results of this study show that the characteristics of computational thinking that each type of learning style dominates are different. Computational thinking students with an assimilator learning style in solving mathematical problems of number patterns can solve issues by involving decomposition, pattern identification, abstraction and generalization, and algorithms. They can generalize patterns using accurate, thorough, complete, and systematic problem-solving strategies.

“…In particular, the use of student-centered approaches to teaching and learning of integers has been recommended. Cetin (2019) argued that teachers should no longer teach students the concept of integers through rules. He added that modelling has more significant benefits and helps students better understand integers.…”

Learning through virtual manipulatives: Investigating the impact of Gizmos-based lessons on students’ performance in integers

Understanding integers is critical for further learning in mathematics. However, most students have difficulty understanding integers, especially how to apply sign rules. This study adopted a mixed-method and action research approach to investigate the impact of a virtual manipulative tool (Gizmos) on students’ performance in addition and subtraction of integers. It also explored students’ perceptions of the Gizmos-based intervention. A multistage sampling was used to select 44 year 9 students in one of the secondary schools in Brunei, who were subjected to a Gizmos-based lesson intervention on addition and subtraction of integers. Data were collected through pre-test, post-test, and interviews. Our paired sample t-test showed that student performance after the intervention improved significantly. The results also revealed that the Gizmos-based intervention provided an opportunity for students to play, learn, and visualize integers, enhancing their confidence, understanding, and performance. However, they found it challenging to memorize the rules during Gizmos-based lessons. Based on our results, Gizmos can be an effective tool that can help improve student performance in addition and subtraction of integers when carefully implemented. It has dynamic representative features that provide quick feedback to students when dealing with integers. It is recommended that teachers should continuously guide students to understand and apply sign rules and instructions in using Gizmos.
