Meningkatkan Estimasi Reliabilitas Instrumen Pilihan Ganda dengan Memperhatikan Probabilitas Guessing

Reliability coeficient is a number which refer to stability result of an instrument measurement. The higher coeficient of reliability, the hingher trusted result of the instrumen will be. The degree of confidence of an intsrument, is expressed by reliability coefisient. For multiple choice instrument, estimation of reliability mostly calculated by KR-20. KR 20 formula calculate estimation of reliability instrumen by using correct score method. This study aims to comphere estimation of reliability coefficient by using KR-20 formula and by considering guessing probability. Hopely by considering guessing factor, estimation of reliability coefficient will increase

Pemberian Rangkuman sebagai Strategi Pembelajaran

This paper discusses the provision of a summary as one component of the learning strategy that plays an important role in improving learning outcomes optimally. Summaries can be done at the beginning of learning, and can also be given at the end of the lesson. Giving a summary at the beginning of learning, work gives an overview on the learner about the content of the material will be presented, and help learners to determine attitudes toward the content of these materials will be presented. While granting summary of a presentation made at the end, serves to review the main ideas of the material that has been presented so that there is an opportunity for students to recall material that has been presented it. So the summary is a component of a strategy that includes all the content areas of study are important, such as understanding ¬-brief understanding of the concepts, procedures, or principles learned. There are five types of summaries are often used in learning, namely: verbal summary, summary charts, summary tabulations, summary groves, Summary schematic. While giving a summary of strategies that are often used, namely: learners is asked to make a summary of what has been taught, and learners is asked to make a summary of what has been read to show a better performance

Pengaruh Jumlah Alternatif Jawaban Dan Teknik Penskoran Terhadap Reliabilitas Tes

This study aimed to determine the effect of the number of alternative answers and scoring techniques to reliability test. Forms of this test includes multiple choice test three answer choice and multiple choice test four answer choices with penalty scoring techniques (Punishment Score) and scoring techniques compensation (Reward Score). The method uses the experiment, while the designused istreatment bylevel 2 x 2. Research hypotheses were tested using two way analysis of variance (ANOVA). The result concluded that: (1) reliability tests with three multiple choice answer options is higher than the multiple choice test four answer choices, (2) reliability tests with scoring techniques penalty higher than the reliability of the technique of scoring compensation, and (3) No interaction between the number of alternative answers to the scoring technique. The results of this study can be considered for the teacher to give test using a form of multiple choice test three answer choice and multiple choice test four answer choices test scoring with a penalty techniques
