title: S4 Changing Matter Elementary Science Task

description: &lt;h3&gt;Project Overview&lt;/h3&gt;
In this four-year project called Developing Preservice Elementary Teachers' Ability to Facilitate Goal-Oriented Discussions in Science and Mathematics via the Use of Simulated Classroom Interactions (GO Discuss), Educational Testing Service and Mursion developed, piloted, and validated a set of performance-based tasks delivered within a simulated classroom environment in order to improve preservice elementary teachers’ ability to orchestrate discussions. These tasks provided opportunities for preservice teachers in science and mathematics to facilitate discussions with five upper elementary student avatars (fifth grade) where the focus is on disciplinary argumentation within two content domains: fractions (mathematics) and structure/properties of matter (science). The overall goal of this research was to develop a validity basis for the use of such tools as formative assessment tasks that can be integrated within educator preparation programs to increase the amount, variety, and quality of clinical practice opportunities currently available to preservice elementary teachers.&lt;br&gt;&lt;p&gt;

&lt;p&gt;For this project, we developed eight performance-based tasks, four in mathematics and four in science, designed to be used by pre-service elementary teachers as they practice leading classroom discussions in the simulated classroom. Each task provides a scenario and specific details about the discussion, including the student learning goal, students’ background information, and what happened prior to the discussion. We also included the student work related to the mathematics problem or science investigation that was the focus within that task and a summary of important things that we wanted the pre-service elementary teachers to notice about the student work. &lt;br&gt;

&lt;p&gt;This specific data project includes materials for one elementary science task called Changing Matter. In this task, students in small groups mixed together different combinations of substances and determined whether each combination produced a new substance. The pre-service teacher leads a discussion on the various claims each group made about whether new substances were formed and the types of evidence that can support or refute the students’ claims. Materials for pre-service teachers, resources for teacher educators, including sample videos, and task-specific simulation specialist training materials are included.&lt;br&gt;

&lt;p&gt;For a complete description of the broader “Go Discuss” project, including a list of files for each task, as well as to read the detailed Terms of Use, please start by reading the &lt;a href="https://doi.org/10.5064/F6QPV2QK/5PLNNH"&gt;Data Overview&lt;/a&gt; file. Some files appear in different formats with identical content. This is intentional. ETS wants to encourage adaptation of the deposited materials (which might be easier to implement in Word documents), but also wants to ensure that images and math notations are rendered correctly for secondary users (best preserved in PDF).

description: &lt;h3&gt;Project Overview&lt;/h3&gt;In this four-year project called Developing Preservice Elementary Teachers' Ability to Facilitate Goal-Oriented Discussions in Science and Mathematics via the Use of Simulated Classroom Interactions (GO Discuss), Educational Testing Service and Mursion developed, piloted, and validated a set of performance-based tasks delivered within a simulated classroom environment in order to improve preservice elementary teachers’ ability to orchestrate discussions. These tasks provided opportunities for preservice teachers in science and mathematics to facilitate discussions with five upper elementary student avatars (fifth grade) where the focus is on disciplinary argumentation within two content domains: fractions (mathematics) and structure/properties of matter (science). The overall goal of this research was to develop a validity basis for the use of such tools as formative assessment tasks that can be integrated within educator preparation programs to increase the amount, variety, and quality of clinical practice opportunities currently available to preservice elementary teachers. &lt;br&gt;&lt;p&gt;

&lt;p&gt;This specific data project includes materials for non-task specific simulation specialist training. A simulation specialist serves as the “human-in-the-loop” during each simulated discussion. The simulation specialist is trained to provide student responses and control the movements of the student avatars in the simulated classroom. The non-task specific training teaches simulation specialists about the five student avatars and their unique vocal and background profiles. We also provided training on specific guidelines, called simulation discussion guidelines, that include information on standard protocols we wanted all simulation specialists to follow during the discussions for how to respond to the teacher’s prompting (or lack of prompting) to engage the students in direct peer-to-peer interactions. The non-task specific training also included instruction on how to set up and use the various technology components, including how to video record the pre-service teachers’ discussion performances and how to use the shared workspace. &lt;br&gt;

&lt;p&gt;The task-specific simulation specialist training for each task can be found in that task's respective data project.

&lt;p&gt;For a complete description of the broader “Go Discuss” project, including a list of files for each task, as well as to read the detailed Terms of Use, please start by reading the &lt;a href="https://doi.org/10.5064/F6Z5ZNWH/PN2NSR"&gt;Data Overview&lt;/a&gt; file.

title: NOAA/WDS Paleoclimatology - Zhang - Xian Yu Mountain - PITW - ITRDB CHIN085

description: Extremely cold temperatures are a significant threat to agriculture and transportation in winter in southeastern China. However, due to the shortness of instrumental records and the scarcity of long-term temperature reconstructions, more high-quality temperature reconstructions are still needed to fully examine their spatial-temporal variability over the past several centuries. In this study, we built an earlywood width (EWW) chronology, a latewood width (LWW) chronology, and a tree-ring width (TRW) chronology using tree-ring samples of Pinus taiwanensis Hayata from the western Tianmu Mountains and the Xianyu Mountains in southeastern China. The tree growth-climate relationships were analyzed, and we found the strongest correlation between December and March mean temperature and the EWW chronology. The December-March mean temperature history was then reconstructed over the period of 1871-2016 using a linear regression model, which is the first EWW-based temperature reconstruction in southeastern China. With a higher explained variance (47.0%) than that (31.7%) of a previous reconstruction using a TRW chronology, the quality of the model has largely improved. This reconstruction was also comparable with other nearby records, further demonstrating the reliability of our new model. Furthermore, our reconstruction exhibits a significantly negative relationship with the East Asian winter monsoon index (EAWMI) since the 1920s, which may be attributed to the obviously enhanced EAWMI thereafter.
