Abstract

AbstractThe background of this research is difficulty of understanding chemical concepts by students. The teacher-centered learning strategy causes students potential and abilities at learning activities in the classroom does not develope. This research aimed at analyzing how student science process skill at the eleventh grade of Natural Science through Practical Work method, analysis is the first step for teacher to develop process-oriented learning strategies. It was conducted at the eleventh-grade students of Natural Science on Reaction Rate lesson at the first semester in the Academic Year of 2018/2019, and it was administered at State Senior High School 2 Siak Hulu. It was a quantitative descriptive research. Purposive sampling technique was used in this research and the samples were 34 students. The instruments used to know student response and to strengthen the results of the obtained data were practicum performance instrument, essay test, and interview. The results of analyzing the data showed that student science process skill through Practical Work method overall was on enough category.  The highest aspect of the science process skill was observing with 53,3% mean percentage, and the lowest aspect is classification with 34% mean percentage. The highest aspect through essay test is communicating with 58.5% mean percentage, and the lowest aspect is classifying with 36.4% mean percentage. Keywords: Science Process Skill, Practical Work Method, Reaction Rate

Abstract

AbstractThe research is an experimental research, motivated by the results of studying chemistry Pharmacy Vocational High School students Ikasari Pekanbaru which is still low with an average value below the Minimum Learning Mastery Standard (KKM) and lack of interest of students reading chemistry books.The aim of the study is to improve students’ learning outcomes on the subject in the 10th grade Stoichiometry. The samples in this study were taken from two classes of the X5 as experimental class and class X4 as the control class. The sample is selected by using simple random sampling. Data collection techniques in this research are used to test the homogeneity as preliminary data on previous material, documentation, observation, pretest and posttest as the final data. To determine whether or not a sample is homogeneous, the analysis employs Bartlet test, and to end the data the "t" test is used. Final data processing results obtained by value tobtain = 16.65 and ttable = 1.99 and showed tobtain>ttabel.So H0 is rejected, indicating the influenced of PQ4R strategy concept hierarchy based on learning outcomes are seen from the average difference posttestexperiment at 77.36, and 74.75 with control influence coefficient of 17.97%.Keywords: learning outcomes, PQ4R, Hierarchy concept, stoichiometry
