PERBEDAAN HASIL BELAJAR SISWA YANG DIAJARKAN DENGAN MODEL PEMBELAJARAN KOOPERATIF TIPE THINK PAIR SHARE DAN MODEL PEMBELAJARAN KONVENSIONAL

This research is motivated by student mathematics learning outcomes on the material two-dimentional figure still low. The learning process is still teacher-centered and there is a lack of good cooperation between students in discussions when the learning process takes place. This research is an experimental study that aims to determine whether there are differences in student learning outcomes taught by cooperative models Think Pair share and learning models The conventional research design used is Nonrandomized Control Group Posttest Design. The population in this study were all eighth grade students of Ambon-Wathan High School with 100 students and the sample in this study was 40 students, selected using purposive sampling. The instrument used in this study was in the form of test questions which consisted of question details for the final test. The analysis used is statistical analysis, which is t-test. Calculation results obtained, namely the value of Sig. (2-tailed) < α or 0.026 <0.05 which causes H0 to be rejected and H1 to be accepted. Based on the accepted hypothesis, the results of the study showed that there were differences in the learning outcomes of the experimental class and control class students who were taught with the Cooperative learning model of the Think Pair share type and the conventional learning model on the Material of Blocks and Beam

Comprehensive Riparian Mapping of the Colorado Plateau Ecoregion

<p>Riparian areas of the Colorado Plateau Ecoregion (CPE) are among the most productive and diverse ecosystems in this semiarid region. These small, yet vital ecosystems support a myriad of aquatic and terrestrial species while simultaneously providing valuable ecosystem services. Maintenance of these important ecosystems requires accurate delineation and characterization. Nevertheless, accurate and comprehensive riparian zone mapping currently doesn’t exist.</p> <p>This project aims to accurately delineate valley bottoms, while characterizing riparian areas and rivers throughout the CPE. The results of this project will provide a comprehensive CPE wide inventory of the distribution and condition of riverine riparian areas. This riparian inventory will serve as an important baseline tool for threat abatement, and for monitoring ecological responses to natural and anthropogenic actions and change.</p

Changing the system by changing the workforce: employing consumers to increase access, cultural diversity, and engagement

Services to families have traditionally been delivered in a medical model. This presents challenges including workforce shortages, lack of cultural diversity, lack of training in strength-based work, and difficulty in successfully engaging and retaining families in the therapy process. The system of care (SOC) effort has worked to establish formal roles for caregivers in SOC to improve services. This paper provides an example of one community\u27s efforts to change the SOC by expanding the roles available to caregivers in creating systems change. It describes the model developed by Communities of Care (CoC), a SOC in Central Massachusetts, and its evolution over a 10 year period. First person accounts by system partners, caregivers hired into professional roles as well as a family receiving services, demonstrate how hiring caregivers at all levels can change systems and change lives, not only for those being served but for the caregiver/professionals doing the work. It also demonstrates, however, that change at the system level is incremental, takes time, and can be fleeting unless an ongoing effort is made to support and sustain those changes

50 Years of Quantum Chromodynamics

International audienceThis paper presents a comprehensive review of both the theory and experimental successes of Quantum Chromodynamics, starting with its emergence as a well defined theory in 1972-73 and following developments and results up to the present day. Topics include a review of the earliest theoretical and experimental foundations; the fundamental constants of QCD; an introductory discussion of lattice QCD, the only known method for obtaining exact predictions from QCD; methods for approximating QCD, with special focus on effective field theories; QCD under extreme conditions; measurements and predictions of meson and baryon states; a special discussion of the structure of the nucleon; techniques for study of QCD at high energy, including treatment of jets and showers; measurements at colliders; weak decays and quark mixing; and a section on the future, which discusses new experimental facilities or upgrades currently funded. The paper is intended to provide a broad background for Ph.D. students and postdocs starting their career. Some contributions include personal accounts of how the ideas or experiments were developed
