The Subject

This study aims to see the improvement of problem solving abilities of mathematical students of smp with the model of assisted PBL Geometer's Sketchpad, this study is quasi experimental because in this study subjects are not grouped randomly, but researchers accept the state of the subject as it aims to see the improvement of problem-solving skills and the ability of mathematical reasoning with PBL-aided model of Geometer's Sketchpad. The population of this study is all students of class VIII SMPN 2 Sindangagung Kuningan, the sample of the study is a class VIII students as much as two classes. The study consisted of two groups, the group with the learning of PBL with Geometer's Sketchpad and the group with conventional learning. Each group consists of thirty students. Research data were collected through problem-solving test, and observation. Data analysis is done qualitatively and quantitatively. Quantitative analysis was done by using t-test and nonparametric Mann-Whitney. Qualitative analysis is done by observing the observation data. From the plot diagram it can be seen that problem solving ability is increased in students with low category. The results of this study are (1) Improved problem-solving abilities that obtained a better learning model than students who received regular learning

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

International Assessment

This study builds an empirical research model that explores societal and individual antecedents of adult learning and examines the adult learning effect on problem-solving skills in the Organization for Economic Cooperation and Development (OECD) countries. Considering national differences, it uses multilevel data sources available from the Programme for the International Assessment of Adult Competencies (PIAAC) 2008-2013 and the OECD data lab. The results from this study suggest that young adults (25- to 34-year-olds) with more favorable backgrounds benefit from their social origin and occupational environment in terms of nonformal learning participation. It was also found that the participants outperform nonparticipants in the PIAAC problem-solving skill assessment. The key findings of this study advocate for the importance of policy interventions to combat the cumulative effects of multiple disadvantages in the educational trajectory from initial education to adult learning as well as to reduce the problem-solving skill gaps of young disadvantaged adults.

The Impact

<p>The aim of the present research was study of the impact of music therapy on problem-solving skills of 4 to 6 years old children in Tehran. This research was a quasi-experimental study with pretest-posttest control group. The statistical population was all 4 to 6 years old children in region 2 of Tehran. Using the random sampling method, the study sample was chosen in two experiment (15 individuals) and control (15 individuals) groups.   The experiment group received 12 sessions of music therapy and the control group was waiting for treatment meanwhile. To evaluate the problem-solving skill in children, the three subscales of Wechsler’s Preschool and Primary Scale of Intelligence (WPPSI) were used, including: mazes, cubes and arithmetic.  Analysis of data obtained from the questionnaires was conducted in two parts of descriptive and inferential. The data analysis indicated the significant increase of problem-solving average score of the experiment group compared to the control group.</p>
