Abstract

This descriptive research aims to analyze level and cause of student’s misconceptions on reaction rate topic. The subjects in research are 27 students of Grade XI IPA 1 students of SMAN 1 Ma'rang. The instruments are used in this experiment are essay test, observation sheet and semi-guided interviews. The data was analyzed by descriptive statistic method to obtain percentage of the misconception. The results showed that students’ misconception occurs in some of the sub concepts of reaction rate material. Percentages and categories of students’misconceptions on understanding the reaction rate, the factors that affect the rate of reaction , and the reaction order , are respectively 15 % is included in the low category , 18.7 % , including in the low category , and 15 % are included in the low category . Overall average student misconceptions on the material that is the reaction rate of 16.2 %. This shows that the misconception on the material reaction rate is low. The results also show that the misconception is caused by: 1) Students, the student preconceptions wrong, 2) Master, which does not provide an explanation in detail to the concept.

Abstract

The research was a quasi-experimental that aimed to know the positive effect of using mind mapping method on learning cycle 5E models towards student achievement at class X Senior High School 1 Kajuara. The population in experiment was class X Senior High School 1 Kajuara Bone Regency are 9 Class with 320 peoples, the sample of this research consisted of two classes, namely class X1 as a experiment class with the number of students was 28 and class X4 as a control class with the number of students 30 peoples. The independent variable in this research was using mind mapping noted technique on learning cycle 5E models and without mind mapping noted technique on learning cycle 5E models, the dependent variable was learning achievement on subject matter Chemical Bond. Data which get form descriptive and inferential analysis. From analysis get the average value of experiment class is 71 with deviation standard is 9.35 while in control class the average is 65.30 with deviation standard is 10.14 and the percentage in class experiment is 57.14% while control class is 30%. The result of hypothesis analysis use t-test got tcalculate = 2.21 and significant level α = 0,05 with dk = 56 got ttable = 1,66. So that, tcalculated > ttable, so H1 accepted and H0 rejected. It means that mind mapping noted technique on learning cycle 5E model has effect toward student achievement class X Senior High School 1 Kajuara Bone Regency in chemical bond matter.

Abstract

The main objectives to be achieved from this research is to produce books Scientific learning model - Enquiry and supporting devices such as lesson plans, worksheets and valid assessment tools, practical and effective in improving students' scientific thinking skills. Instructional material used as the focus of this research is the solution of electrolyte and non-electrolyte that is presented in class X semester. Activity presents a real problem in the class is the first step of learning, so it is expected that students are able to analyze problems, hypothesize, collect the data and concluded through experimentation. This is not apart of the activities 5 M (Observe, ask, reasoning, Tried and Communicate) which is the scientific thinking activities of students. The development method used is Plomp (1997), which consists of four stages, namely; 1) The initial assessment by observation early in the school curriculum, the students and the state sylaby appropriate learning model; 2) planning draft of the model scientific - inquiry and materials suitable for development, 3) realization & Construction to develop the book model of scientific - inquiry together with learning devices namely lesson plans, worksheets and assessment tools skills of scientific thinking of students, while stage 4) implementation has not been done for I. year study the validity of test results from three experts to book models and devices obtained by each (book model = 3.23; RPP = 3.29; LKS = 3.19 and assessment tools = 3.10) total mean with a 3.20 average coefficient of expert judment index equal to one category is valid. Test the practicality of the model and the Scientific - Inquiry through perception questionnaires gained an average of 89.47% of students (32 students) who respond positively to the application of models and tools, and of the three chemistry teacher at SMAN 1 Bajeng average of 90.05% giving a positive response to the model and the device. Test the effectiveness evident from the test results show class completeness of 81.25% (26 students completed). Feasibility study can be seen from the observation of student activity associated with formulating problems, observe, ask questions, give argimen, formulate hypotheses, collect and data analyze, discuss, cooperation and conclude group average of 75.83%. Based on these two indicators show that the model and the device is effective to improve learning outcomes and scientific thinking skills.
