Instrumen penilaian ini dapat mengukur, sekaligus melatih peserta didik dalam meningkatkan kemampuan berpikir kritis.Kata kunci: Asesmen Fisika, SMA, Tes Essay Abstract. High school students are used to passive thinking, even in a science subject. Commonly the content of the material is not conveyed. Assessment instruments that focus on applying Newton's Laws, especially without numerical calculations, are still hard to find. The research aiming to develop the assessment instrument for measure critical thinking in the dynamic particle subject, then test the standardization of the instrument.  The research method used Research and Development, with the steps: defining the construct, determining the format, making an assessment guideline, theoretical validation, field testing, and standardization analysis. Trial of 67 students who have studied dynamics particle subject. The test results concluded eight valid questions, with a reliability of 0.86 consider very high value, with the level of difficulty: one difficult question and nine medium questions, and discrimination power: two very discriminate, two discriminate, four fair, and two without discrimination questions. This instrument can evaluate, as well as train students in improving critical thinking skills.Keywords: Physics Assessment, High-School, Essay Tes

THE EFFECT OF STUDENT WORKSHEET BASED ON PREDICT OBSERVE EXPLAIN STRATEGY AGAINST THE LEARNING OUTCOMES

The study was aimed to determine the influence of the use of student worksheet (LKPD) based on Predict Observe Explain (POE) strategy on student learning outcomes in the light material. This research was an experimental study with the design of experimental quasi using the form of a one-group pretest-posttest. The population of this study was the eighth-grade students of junior high school (SMP). Data analysis techniques were tested with the learning result grouping techniques, N-Gain analysis, hypothesis testing, linear regression tests, t-test paired test and effect size tests. The result of the N-Gain was a value of 0.60 with a moderate N-Gain interpretation.  Linear regression test result was obtained a coefficient value of 0.7, with the sig regression value of 0,0. The result of the paired t-test achieved a significance value of 0.0, which indicated that there was a raise prior and following treatment. The result of the effect size test was 0.31 with a medium interpretation. The learning outcomes for psychomotor learners had an average value of 3.52 with excellent interpretation. Based on these findings, it can be concluded that the POE strategy-based LKPD was considerably effective to be applied in schools resulting in an increasing effect of the students learning outcomes before and after the treatment of POE-based LKPD

Pengaruh Tingkat Intelegensi Dan Motivasi Belajar Siswa Terhadap Hasil Belajarfisika Siswa

Learning is the most vital key term in every education effort, therefore without the real learning there will nothing about education. Individual achievement of the learning process called studying’s result. One of the internal factor that can influence someone’s studying result is intelegency and learning motivation. The research is to know : (1) The influence of the intelegensi against the learn physics the students , (2) The influence of motivation learn to the students learn physics the students , (3) The influence of the intelegensi and motivation learned to learn physics the students. This research was conducted in SMAN 13 Bandar Lampung that exerting one experimental class (X5) which 35 students as the sample. The studying’s result measured by the result of posttest evaluation, whereas the intelegency gained by taking from the research sample that use documentation technique. The data of learning motivation gain from the student’s learning motivation questionnaire. The data tested by SPSS 17.0 there are regression test, normality, homogenity and linearity. Based on the test result showed that : (1) There was influence of intelegency toward studying’s. (2) There was influence of motivation toward studying’s. (3) There was influence of intelegency and learning motivation toward studying’s
