Analysis Science Process Skills Content in Chemistry Textbooks Grade XI at Solubility and Solubility Product Concept

<p class="Abstract">The aim of this research was to determine the analysis of science process skills in textbooks of chemistry grade XI in SMA N 1 Teras, Boyolali. This research used the descriptive method. The instruments were developed based on 10 indicators of science process skills (observing, classifying, finding a conclusion, predicting, raising the question, hypothesizing, planning an experiment, manipulating materials, and equipment, Applying, and communicating). We analyzed 3 different chemistry textbooks that often used by teachers in teaching. The material analyzed in the book was solubility and solubility product concept in terms of concept explanation and student activity. The results of this research showed different science process skill criteria in 3 different chemistry textbooks. Book A appeared 50% of all aspects of science process skills, in Book B appeared 80% of all aspects of science process skills, and in Book C there was 40% of all aspects of the science process skills. The most common indicator in all books was observing (33.3%), followed by prediction (19.05%), classifying (11.90%), Applying (11.90% ), planning experiments (9.52%), manipulating materials and equipment (7.14%), finding conclusion (4.76%), communicating (2.38%). Asking the question and hypothesizing did not appear in textbooks.</p>

This research is a quasi experimental research and design used is ARandomized Pretes-Postest Control Group Design. The subject of the researchdetermined by random toward experimental and control groups. The results of this studyshowed that there was differences class between implements the inquiry learning andconventional learning. Mean score N-Gain science of process skills students washighest in primary schools reached 0.29 A, while for the N-Gain lowest in primaryschools C of 0.15 As for the indicators of science-process skills, process skills of thehighest indicators in the experimental class there is the aspect of the hypothesis, whilethe lowest indicator contained in the aspect of the question. In the control class there areindicators that contained by aspects of the hypothesis while the lowest was on aspects ofobservation. The results visible experimental class science process skills results showedhigher levels of N-gain control of the class. The results in the experimental classsignificantly more improve students’ science process skills than conventional class.Keywords: Science Process Skills, Learning Science

This research aims to design multimedia based teaching materials model of Basic Analytical Chemistry that oriented on the explanation of macroscopic and microscopic level and symbolic, and its implementation to improve the mastery of science concepts and labwork skills of student teacher candidates. The subjects consisted of 27 and 30 students of chemistry education study program who take Basic Analytical Chemistry lecture as control and experimental group respectively. Quasi-experimental design with pretest - posttest control group used in this study, and the differences of pre and post-tests result were assumed as the effects of the treatment. Mastery of concepts and skills of science process measured by description test was analyzed by comparing the value of the normalized gain (N-gain), whereas questionnaires students feedback was analysed with descriptive percentage. Learning basic analytical chemistry using a CD-oriented learning material that oriented on the structure of matter on acid-base and permanganometric titration can improve mastery of concepts and skills of science proces. The highest indicators of science process skills was classifying and the lowest was hypothesize capabilities. The advantages of learning implementations were increasing mastery of the concepts and science process skills and making a fun learning experience among the students.
