This research is a descriptive study that aims to determine students’ problem solving abilites after using the SSCS learning model. The subjects of this study were 25 students of class VIII MTs Persis 72 Gunung Buntung. The learning process is carried out in accordance with the SSCS learning steps. The collection technique used tests and interviews. Based on the research result, it was foud that the percentage of students who had the ability to solve problem very well was 20%, the percentage of students who had good problem solving abilities was 72%, the percentage of students with sufficient problem-solving abilities 8%. Meanwhile, the highest percentage of problem solving ability indikator is identifying the coverage of data to solve the problem of 89,33%. Meanwhile, the lowest percentage of problem solving ability indicatoris checking the correctness of the results or answers by 64,32%.

Bandits in the lab

We experimentally implement a dynamic public‐good problem, where the public good in question is the dynamically evolving information about agents' common state of the world. Subjects' behavior is consistent with free‐riding because of strategic concerns. We also find that subjects adopt more complex behaviors than predicted by the welfare‐optimal equilibrium, such as noncut‐off behavior, lonely pioneers, and frequent switches of action.

Analisis Problem Solving Skills Siswa pada Materi Lingkungan

The purpose of the research was to find out the level of the students' problem solving skills on environmental material at X class of MAN Bintan. The researcher applied descriptive quantitative approach as method for analyzing the data. Sampling in this study using Total Sampling technique with the sampel consisted of 59 students. This instrument is used to collect students' problem solving skills through six aspects to Chang & Kelly with 6 items essay and feature interviews. The data were analyzed with statistical rule in percentage. Based on the results of data analyze shows that a 77% rate highly classified. The researcher concluded that student at X class MAN Bintan has good problem solving skills. However, it still needs training and guidance to develop problem solving skills.

Penggunaan Model Problem Solving Dalam Menyelesaikan Soal Cerita Matematika Di SDN 211/Ix Mendalo Darat

This study presents the problem that is solving math story question is a difficulty for students so the teacher uses a problem solving model and students will find it easier to understand the meaning of the story question and be able to solve them. The research design is qualitative and descriptive approach. The subjects in this study were the principal, student guardians of grade 4 (mathematics teacher), and students. Data collection techniques were in the form of interviews, observation, and documentation. The results of this study indicate that by planning, implementing, evaluating the use of a good problem solving model will be able to solve problems, with the obstacles and efforts will be get a good result.

Landasan Pembelajaran sains Terintegrasi (Terpadu) Untuk Level Dasar

Buku Landasan Pembelajaran Sains Terintegrasi Untuk Level Dasar ini disiapkan untuk digunakan oleh guru-guru sebagai praktisi di level dasar yakni guru sekolah dasar (SD) dan guru sekolah menengah pertama (SMP). Hal ini sangat membantu pendidik dalam menyajikan pembelajaran saains secara terpadu kepada peserta didik sehingga mereka mampu memahami sains secara utuh dan bisa menerapkannya dalam memecahkan masalah dalam kehidupan sehari-hari. Dengan demikian pemebelajaran sains terpadu memberikan dampak terhadap peningkatan rasa ingin tahu (coriusity) mereka yang pada akhirnya mampu merubah perilaku menjadi gennerasi yang kritis, kreatif, good problem solver, dan inovatif. Dasar pemikiran lahirnya buku ini adalah belum adanya buku penunjang untuk guru atau pendidik supaya mereka bisa memahami pembelajaran sains terintegrasi (terpadu) dengan baik serta mampu membelajarkan peserta didik sesuai harapan tujuan pendidikan nasional yang disusun berdasarkan riset dan pengembangan secara metodologis akademik dan empirik serta divalidasi oleh pakar kependidikan. Dengan demikian, buku ini diharapkaan dapat menambah wawasan para guru dan calon guru mengenai pendidikan sains dan pembelajaran terpadu dalam rangka memperkuat pemahaman akan landasan pembelajaran sains terintegrasi di level dasar atau pendidikan dasar.

Good problem solvers? Leveraging knowledge sharing mechanisms and management support

Purpose Organizational learning relies on problem-solving as a way to generate new knowledge. Good problem solvers should adopt a problem-solving orientation (PSO) that analyzes the causes of problems to arrive at an effective solution. The purpose of this paper is to investigate this relevant, though underexplored, topic by examining two important antecedents of PSO: knowledge sharing mechanisms and transformational leaders’ support. Design/methodology/approach Hierarchical linear modeling analyses were performed on a sample of 131 workers in 12 plants. A questionnaire was designed to collect data from shop-floor employees. Knowledge sharing was measured using the mechanisms of participative practices and standardized practices. Management support was assessed based on the extent to which supervisors engaged in transformational leadership. Findings Knowledge sharing mechanisms are an antecedent of PSO behavior, but management support measured in terms of transformational leadership is not. However, transformational leadership affects the use of knowledge sharing mechanisms that, in turn, is positively related to PSO behavior. Practical implications The research provides practical guidance for practitioners to understand how to manage knowledge in the workplace to promote employees’ PSO behaviors. Originality/value Though problem-solving activities are intrinsic in any working context, PSO is still very much underrepresented and scarcely understood in knowledge management studies. This study fills this gap by investigating the antecedents of PSO behavior.

The Rise of Flourishing Societies

This chapter explains how societies can climb a development ladder whereby each step leads to a larger set of transactions through which to increase the value of output per capita. Each step higher is harder because each step adds transactions that require higher levels of social trust. The problem is that many of the benefits of climbing the ladder are realized at the level of society as a whole, so individual adults and individual parents have much to gain by conserving on their own resources while allowing everyone else in society to invest into the inculcation of the required moral beliefs to produce a high-trust society. There is a public good problem associated with investing enough to best promote the common good. This problem is particularly daunting for the kind of moral beliefs required to produce trustworthy individuals and it worsens with societal success.

Good Problems within and Across Disciplines

This paper focuses on the question of what makes a good disciplinary or interdisciplinary problem. We draw from literature across the STEM disciplines and two conference sessions to provide insight into what makes a good problem within a specific discipline and across the disciplines. We use various frameworks to analyze a variety of problems that were nominated as exemplars by STEM education research experts. Common features identified include real-world connections, reinforcement of conceptual understanding, a low floor and high ceiling, multiple solutions paths, and building dispositions of professionals in the discipline. While a good problem need not have all of these features, in general, good problems have more of these features. We also recognize that these problems are context-specific, as what may be considered a problem for one learner could be a trivial exercise for another. We discuss some of the challenges of designing good interdisciplinary problems and identify some features that can make a problem interdisciplinary, including use of cross-cutting concepts and drawing on the specific expertise of each discipline.
