The Effectiveness of Multiple Representation Oriented Learning Material with Project Based Learning to Improve Students' Chemistry Learning Outcomes

Abstract

Learning material is one of components in learning that its existence can improve students' learning outcomes. The Existence of learning material that has low quality, so making learning material needs consideration. The formulation of research problem is how the effectiveness learning material multiple representation oriented? This research for intended to analyze the effectiveness learning material multiple representation oriented towards improvement of students' learning outcomes and know the students' responses to learning material multiple representation oriented. The implementation of multiple representation-oriented learning material is done in colloid system chapter through Project Based Learning (PjBL). This research uses 46 of sample with mix method research design. The result show that implementation of multiple representation-oriented learning material is effective to improve students learning outcomes from 18.41% become 85.12%, N-gain is 0.82 include in high category.

The Analysis of Concept Mastery Using Redox Teaching Materials with Multiple Representation and Contextual Teaching Learning Approach

“…One of the learnings that are connected with daily life is contextual teachinglearning, such as in the research conducted by Drastisianti et al (2018b), who succeeded in explaining the buffer concept by using teaching material of multiple representations through entrepreneurial chemical products. Furthermore, that was strengthened by recent researches on multiple representations which explain that the use of multiple representation learning materials is important in increasing students' understanding of chemical materials (Nada et al, 2018;Pratiwi et al, 2018;2019). Based on the explanation above, teaching materials with multiple representations and contextual teachinglearning approach are needed.…”

Dual Mode Module as New Innovation in Learning Chemistry: Project Based Learning Oriented

“…Engaging students through student-centered pedagogies such as Project-based learning which provides students with opportunities to carry out projects within small groups may likely be beneficial to their deep understanding of the chemical phenomenon involved in the learning process. [12] buttress the fact that when PBL is incorporated with learning materials that carries the three chemical representations, students' understanding might be more deepened and may result in realization of more learning outcomes. Furthermore, [29] highlighted the fact that students' understanding of chemical knowledge in all the three representation levels can be improved if they are granted the opportunity to communicate their own understanding through practice, and so, one of such ways might be through PBL.…”

“…As crucial skills in science, the skills must be encouraged in learning chemistry, it is supported by [11] who found that students' science process skills have a strong relationship with motivations so it also can improve students' motivation in learning chemistry. According to [3], the science process skills can be improved by making students active in learning such as providing them to do projects [12].…”

“…The PBL approach in science fields has provided for students to establish a link between their classroom understanding and real-world experience [14]. Meta-analysis carried out by [12] revealed that the effect of PBL in science education was significantly higher than the traditional learning, though the effect size varied across subject areas. PBL is shown to improve students' psychomotor skills.…”

Developing authentic assessment instrument based on multiple representations to measure students' critical thinking skills

“…Hopfenbeck so that these tests can communicate representations to model and interpret them. Study from Abdurrahman et al (2019); Susilaningsih et al (2019); and Yanti et al (2019) showed that multiple representation can improve the implementation of the learning process starting from planning, student activities during learning, responding to student's very good interest, and providing positive results on students' social skills. The results of the study show that multiple representation can improve student's problem solving ability (Prahani et al, 2016), increase creativity in analyzing tests (Mutia & Prasetyo, 2018), help students stimulate the development of thinking skills with various perspectives and approaches (Fonna & Mursalin, 2018).…”
