Abstract

Education in the 21st century requires students and teachers to master various skills including critical thinking skills. Critical thinking is an aspect that has been researched in recent years with the aim of seeing the thinking skills and cognitive abilities of teachers and students. Therefore this study aims to analyze students critical thinking in answering questions about chemical bonding topic. The sample of this study was 171 high school students in Pekanbaru. Data were analyzed using SPSS 21.0 by looking at the frequency of students in answering questions and elaborating on the answers. The results of the study showed that students were still at a low critical thinking stage based on the frequency of students in explaining and answering the questions given. Based on the results of this study was expected to provided information for teachers to be able to improve cognitive thinking and critical thinking of students and develop a variety of critical thinking questions so that students have a lot of experience in describing problems and understand well the concept of chemical topics.

Abstract: Evaluation is one of the component parts that holds a very important role in learning system. One evaluation conducted is evaluation of students learning result. This study aims to determine the quality of the best items semester chemical subject exam. The object in this study is the second semester exam which amount 40 questions and the answer sheet of the students at class XII MIA SMA Negeri 1 Tapung Academic Year 2016/2017 as many as 71 students. This research is an ex post facto, meaning that the researcher didn’t manipulate the symptoms of research and the symptoms were already present in the real condition. Analysis in this research is qualitative analysis and the quantitative analysis (the difficulty degree, the differentiator, distractor function, validity and reliability). According to the analysis, known that from 40 questions, there are 30 questions acceptable of the matter criteria, 32 questions acceptable of the construction criteria, and 25 questions acceptable of the language/culture criteria. While in terms of this test having poor quantitative quality shown by the difficulty degree was good, the differentiator was not good, distractor function was not function effectively, the validity was enough and the reliability was low. From the quantitative analysis is 33 questions was repaired and 7 questions was rejected.

Abstract: The study of Development chemistry worksheet based problem based learning on acid and base Solutions (chemistry). The result of this Development research is student worksheet product which can be used by students in the process of learning. The device development model suggested by Thiagarajan, Semmel, and Semmel (1974) is a 4-D Model consisting of 4 stages, such as: Define, Design, Develop, and Disseminate. The research development with 4-D model was conducted only Define, Design, and Development step, because the purpose of this research was limited to develop and produce a valid student worksheet to be implemented based on validator assessment. The result of research shows as the average score of the four aspect assessment of the student worksheet which is validated: content: 88,125%, language: 98,43%, presentation: 84,375%, and successive graphics: 95,31% by the validators. Thus, the overall average score of student worksheet validation the acid and base solution on Problem Based Learning is 91,56%. Based on the eligibility criteria of learning tools in Riduwan (2012), the criteria of 91,56% analysis included in valid category.Keywords : Student worksheet, Problem Based Learning, Acid and Base Solution(SchoolChemistry).

Abstrack: The research aims to improve student learning achievement on the subject of stoichiometry in class XI MIPA SMA N 9 Pekanbaru. This research was a experiment with randomized group pretest-posttes design. The sample of this study was X IPA 5 as experiment class and X IPA 6 as control class after being tested for normality and homogeneity tests. Normality test was performed using Liliefors test. The results of the Liliefors normality test obtained for all the data (material prerequisites, pretest, and posttest) normal distribution where Lmaks ≤ Ltabel. The results of the homogeneity test, of Fhitung<Ftabel (1,05 < 1,72 with α = 0.05, dk=70) which means that the samples have the same variance (homogeneous). Data analysis technique used was t-test, obtained thitung ≥ ttable (3,4978 > 1,67 with dk = 70 and α = 0.05) means that the application of Means Ends Analysis (MEA) learning model can improve the presensce of the student achievement with criteria for improvinghigh learning achievements which is 0,82 .Key Words: Means Ends Analysis (MEA), student achievement, stoiciometry.
