DESIGN AND EFFECTIVENESS OF MATHEMATICS LEARNING PACKAGES BASED ON BILINGUAL METHOD

Abstract

The specific targets of this research were to produce; (1) Student book (SB), (2) Student Worksheet (SW), (3) Lesson Plan (LP) and to (4) Know their effectiveness of learning packages themselves. The development design of the packages was the modification and adaptation of Four-D model (Thiagarajan, 1974), which is encompassing four phases namely; Define, Design, Develop, and Disseminate. The criteria, used as the references of Bilingual Method, refers to; (1) Indonesian Qualification Framework (IQF), based on President Regulation No. 20/2012, (2) English as a language, in which the packages were made, (3) The examiners are native speakers, (4) The structure of the learning packages, which can lead students’ paradigm, insight, and knowledge to worldwide things. The research finds that: (1) Quantitatively, the learning packages are generally effective to improve students’ achievement, specifically shown by the increase of students’ grade from the pretest to posttest as many as 8.16 in 100-grading scale and, (2) Qualitatively; (a) the development SB emphasizes on three facets namely; the clarity and the structure of the content, the language, and the problem solving, (b) The development of SW emphasizes on three primary aspects namely; the task direction, the order of the task, and the language (c) The development of LP emphasizes on four primary aspects: formulation of basic competency, time allocation, learning material, and its structure.
