A Relationship Between Problem Solving Ability and Students' Mathematical Thinking

This research have a purpose to know is there an influence of problem solving abilty to students mathematical thinking, and to know how strong problem solving ability affect students mathematical thinking. This research used descriptive quantitative method, which a population is all of students that taking discrete mathematics courses both in department of Information Systems and department of mathematics education. Based on the results of data analysis showed that there are an influence of problem solving ability to students mathematical thinking either at department of mathematics education or at department of information systems. In this study, it was found that the influence of problem solving ability to students mathematical thinking which take place at mathematics education department is stonger than at information system department. This is because, at mathematics education department, problem-solving activities more often performed in courses than at department of information system. Almost 75% of existing courses in department of mathematics education involve problem solving to the objective of courses, meanwhile, in the department of information systems, there are only 10% of these courses. As a result, mathematics education department student's are better trained in problem solving than information system department students. So, to improve students' mathematical thinking, its would be better, at fisrtly enhance the problem solving ability

Kata Kunci: Problem Solving, Booklet, Hasil Belajar Abstrack: : This research aims to determine the effect of problem solving with B2M booklet towards response and learning outcome in SMA Negeri 9 Pontianak on buffer material. The research method is quasi-experimental and the research design is Nonequivalent Control Group Design. The sample were the students of IPA1 as control and XI grade of IPA2 as experimental. Data were collected by using learning outcome test and response questionnaire. The result of data analysis using U-Mann Whitney test showed the differences of learning outcome between students of control and experimental. Based on calculation of effect size showed there were effect of learning problem solving with B2M booklet to increase learning outcome around 44,06% (ES = 1,56). Student's response towards problem solving with B2M booklet obtained an average rate of approval 88% (very high)

What Makes A Court Problem-Solving: Universal Performance Indicators for Problem-Solving Justice

This report identifies a set of universal performance indicators for specialized "problem-solving courts" and related experiments in problem-solving justice. Traditional performance indicators related to caseload and processing efficiency can assist court managers in monitoring case flow, assigning cases to judges, and adhering to budgetary and statutory due process guidelines. Yet, these indicators are ultimately limited in scope. Faced with the recent explosion of problem solving courts and other experiments seeking to address the underlying problems of litigants, victims, and communities, there is an urgent need to complement traditional court performance indicators with ones of a problem-solving nature. With funding from the State Justice Institute (SJI), the Center for Court Innovation conducted an investigation designed to achieve three purposes. The first was to establish a set of universal performance indicators against which to judge the effectiveness of specialized problem-solving courts, of which there are currently more than 3,000 nationwide. The second purpose was to develop performance indicators specific to each of the four major problem-solving court models: drug, mental health, domestic violence, and community courts. The third purpose was to assist traditional court managers by establishing a more limited set of indicators, designed to capture problem-solving activity throughout the courthouse, not only within a specialized court context

Pengaruh Metode Problem Solving terhadap Hasil Belajar Siswa pada Konsep Koperasi dan Pengelolaan Koperasi Kelas X di Sman 11 Kota Pekanbaru

This research was conducted at SMAN 11 Pekanbaru with the aim to analyze problem solving method to student learning outcomes. The population in this study were students of class X IPS and Samples performed by using simple random sampling because the samples taken 2 classes based on homogeneity test results from the class. Technique of completion of data is done by observation, documentation and teacher activity sheet then the data is analyzed using homogeneity test test and t test. The result of the research shows that the result of pretest of X class students still get very less category and the result of pretest result of students is done by determining homogenous class with simple random sampling technique and can be homogenous class group that is class X IIS 2 and X IIS 4 Levene's test results 0.819> 0.05 which means that the data comes from a homogeneous variant. After doing the pretest then the homogenity test is done postes The data obtained from the experimental class postes and control classes will be analyzed using levent test. Then get value Pvalue 0,743> 0,05 then this can be interpreted that data of learning result of postest class of IIS 4 and X IIS 2 is homogeneous. After the homes of postes test, then t test analysis from post test of experiment class and control class with 5% (α 0,05) belief obtained significance value 0,007 so it can be interpreted that there is significant difference

Modeling crowdsourcing as collective problem solving

Crowdsourcing is a process of accumulating the ideas, thoughts or information from many independent participants, with aim to find the best solution for a given challenge. Modern information technologies allow for massive number of subjects to be involved in a more or less spontaneous way. Still, the full potentials of crowdsourcing are yet to be reached. We introduce a modeling framework through which we study the effectiveness of crowdsourcing in relation to the level of collectivism in facing the problem. Our findings reveal an intricate relationship between the number of participants and the difficulty of the problem, indicating the optimal size of the crowdsourced group. We discuss our results in the context of modern utilization of crowdsourcing.Comment: 19 pages, 3 figure

Introductory Problem Solving in Computer Science

This paper describes our experiences in devising a lightweight, informal methodology for problem solving in introductory, university level, computer science. We first describe the original context of the experiment and the background to the methodology. We then give the details of the steps of the Problem Solving Cycle - Understanding, Designing, Writing and Reviewing - and the lessons we learned about our teaching from devising the material. We also present practical examples of how it has been applied in a variety of units in our programme
