Abstract

Complex yet hierarchical mathematical material in fact does not mean that the process of schema acquisition and accommodation in long-term memory is easy. For an instance, year seven students learn to solve problems related to the compound area of quadrilaterals and triangles. This problem may be categorized as a well-structured problem, therefore, it might be procedurally obvious to reach the solution, for those who have possessed sufficient prior knowledge of the aspects of the shapes. This study aims to discuss instructional strategy for novices when learning to solve problems like these. Based on a cognitive load theory, the strategy of worked example could be applied effectively for novices. The design of the worked example must be presented in such a way it could minimize extraneous cognitive load. The composite shapes of quadrilateral and triangles might be challenging to be described in an integrated format to avoid the split attention effect. This paper shows how this can be done by using techniques, such as (1) number sequences of the solution steps; (2) different colors for prompting attention resource; (3) less wording, more procedure application; and (4) consistency of layout within overall material. In order to apply these, the instructional designers should follow ADD steps, (1) Analyze the learning content, arrange them accordingly; (2) Design one worked example, evaluate its accuracy and niche; and (3) Develop into several worked example pairs. Two worked example with paired problems have been successfully developed and declare valid. Eventually, it might be suggested that comprehensive consideration when designing worked example that contain pictures should reflects how students use their cognitive resource during learning.

Abstract

PISA is an international scale assessment in which it measure mathematical literacy skills. Indonesia was one of the participants who took part in the PISA assessment. PISA results show that Indonesia is still at a low level. In fact, some study show that the ability of Indonesian students to solve PISA questions on the quantity content of students is not good and is still low compared to other content. This research aims to produce PISA-Like math questions with Quantity content that are valid, practical and have a potential effect on mathematical literacy skills. This research using a development research which consists of preliminary, self-evaluation, expert review, one-to-one, small group, and field test stages. The subjects in this study were students of class IX-4 SMP inone of the junior high schools in Medan. The results of this study are PISA-Like questions with Quantity content in valid and practical criteria. From the analysis of students’ answers regarding the potential effect involved in mathematical literacy, the results show that students involve communication skills, reasoning and argument skills, mathematical abilities, representation abilities, devising strategies for solving problems, and using symbolic, formal skill, and technical language and operations.
