This study aims to improve problem-solving skills and learning achievement by applying the Karplus Learning Cycle Model on students of class VC of SD N 2 Padokan Bantul, totaling 20 students. This research was a classroom action research and was carried out in two cycles.  Data collection techniques were test and non-test. Students’ problem-solving skills data were collected using pretest and posttest as well as observation sheets, while science learning achievement of students was taken using pretest and posttest. The data were analyzed using descriptive analysis techniques. The results showed that problem-solving skills and learning achievements of the students in class VC SD N 2 Padokan can be improved through learning with the Karplus Learning Cycle Model. Each stage of the Karplus Learning Cycle Model can improve aspects of problem-solving skills and student learning achievement. The Exploration stage increases the aspect of understanding the problem. The Explanation phase enhances the aspects of planning a solution. The concept application stage improves aspects of solving problems and evaluating problem-solving. Improved problem-solving skills are proven through test results, where the average N gain of class in the first cycle was 0.37 with the moderate category, up to 0.70 with the high category in the second cycle.  This is also strengthened from the results of observations, where the average scores of the class increase from the first cycle of 67.61% with a pretty good category to 91.66% with a very good category in the second cycle.  The increase in student learning achievements is evidenced through the results of the test, where an increase in the number of students who reached KKM 75 from the first cycle as much as 90% to 100% in the second cycle.

The problem in this research is the low interest of physics student learning influence to the success of a process of physics learning. To overcome this problem, this research applied learning cycle model (Learning Cycle "5E"). This study aims to improve students' learning creativity, student learning activities, teachers' ability to manage learning and students' interest in physical learning through learning cycle model (Learning Cycle "5E") on Cubes and Balok subjects in class VIII-2 SMP Negeri 4 Angkola Timur. Data analysis shows that for the cycle I there is increase cycle II. The result of observation of student activity on cycle I obtained by cycle II increase. Observation on the ability of teachers to manage to learn in cycle I am in the category of "good," and for cycle II there is an increase that is in the category of "very good". The above conclusions suggest that the implementation of the learning cycle model (Learning Cycle "5E") can be used in an effort to increase the students' learning interest in physics and to the teacher, it is expected to implement the learning cycle model (Learning Cycle "5E") on other subjects on physics lessons or appropriate subjects. Keywords: Student Learning Interest, Learning Cycle Model "5e".

Problem-solving skill is required by students and a target in studying mathematics. However, the problem-solving skill of Indonesian students are lacking. One effort that can be done is applying the Model of Learning Cycle 5E.  This research discussed the influence of the implementation of the learning cycle model on mathematics problem-solving skill viewed from students’ adversity quotient. This research used a quantitive approach, quasi-experimental study. The subjects were the 8th Grade students of SMP IT Ash-Shiddiiqi Jambi, consisting of two experiment classes and one control class. The instruments were post-test and adversity quotient questionnaire modified by Stoltz and had been validated by experts. Data analysis was conducted by Two-Way ANOVA. The results showed that there was no interaction between the learning cycle 5E model and mathematics problem-solving skill. This finding indicates that the model of learning cycle 5E affects problem-solving skills and can be applied to students with all types of adversity quotient.

The subject of Economy, specially Accountancy major was the most important lesson in life and for the students it can raise curiosity, fairness, hard work, dicipline and creative and innovative interpreneurship. The problem which is faced nowadays is that economy/accountancy with the main topic Journal of Adaptation is percepived as the difficult lesson for some students. In addition, the teachers do not implement learning model maximally, as the consequence of this condition causes students have less interest in studying it and the result of studying is low. In this research the aspects studied were student learning activity, student’s interest, studying result and student response by using Learning Cycle Model in Accountancy lesson with main topic Journal of Adaptation. This research is a classroom action research with quatitaive approach. The result of this reseach shows that student learning activity increased; in cycle I was 3,20 (not good ) and in cycle II became 4 (good );  students’ interest  in learning at cycle II was 49,74 % (enough)  in second II became 98,05 (very good). The result of studying in cycle II was 78,96 and in cycle II increased became 85,45. The completeness in cycle I was 21 % and in cycle II was 100%. From response using questionnaire it is stated 75,8% of students agreed and liked Learning Cycle Model for accountancy with main topic Journal of Adaptation. In the teaching and learning accountancy the teachers are expected to be able to use various models in learning process in order that it can raise the interest of studying and the result of studying becomes higher.Key Word: Studying of Learning Cycle Model, interest, the result of studying, accountancy Mata pelajaran Ekonomi/Akuntansi adalah mata pelajaran yang sangat penting dalam kehidupan dan bagi siswa dapat menunbuhkan rasa ingin tahu, jujur, kerja keras,disiplin dan dapat menumbuhkan rasa kewirausahaan yaitu kreatif dan inovatif.

The purpose of this research are: 1) to know the learning activity of learners mathematics which is taught by Search, Solve, Create, and Share (SSCS), and 2) model to know the ability of problem solving of mathematics learners who taught by SSCS learning model in the class XI MIA MAN 1 Muara Labuh academic year 2016/2017. This research belongs to a kind of quasi-experimental research with randomized control group only design. In this study design, a group of subjects taken from a particular population were randomly assigned into two groups, the experimental group and the control group. After analyzing the data, it is known that the learning activity of the students after applying the SSCS learning model has improved towards the better from the first meeting to the fifth meeting, ie 35%, 45%, 55%, 68%, 77%. Based on the hypothesis test obtained ttable = 1.645 and tcount = 2.598 so obtained (2.598> 1.645) at 95% confidence interval. Because tcount > ttable then hypothesis in this research accepted. Thus, students 'math-problem-solving skills taught by SSCS learning models are higher than the students' uneducated mathematical problem-solving skills with SSCS learning modelsKeywords: Problem solving abilities, search, solve, sreate and share (SSCS) learning models
