The bubble temperatures are computed by setting the target y1+y2=1 by changing the estimated temperature. This is repeatedfor each composition for each model.Pure Component DataAntoine CoeffABCVL (cm3/mol)d (cal/cm3)1/21MeOH8.080971582.271239.7264014.52benzene6. 879871196.76219.161889.2Mixture data to be used in all sets:Methanol+benzene data from Perry's 6th p13-12 and 13.59 P =760mm Hgx100.0260.050.0880.1640.28420941450.3330.5490.6990.782 0.8980.97303263260.9731y100.2670.3710.4570.5260.5590.5950 .6330.6650.760.9071T (C)80.170.6766.4462.8760.258.6458.0258.158.4759.962.764.7C alculations based on dataT(K)353.25343.82339.59336.02333.35331.79331.17331.253 31.62333.05335.85337.85F100.01198819620.0233644860.04201 680670.08186900960.15288717440.1849588980.35621593560.5 1351748460.61984781230.80007127580.94253152010.9424641 6121Scatchard-Hildebrand model with zero binary interaction coefficient (x's from above) see plot ---- >x100.0260.050.0880.1640.28420941450.3330.5490.6990.7820. 8980.97303263260.9731g14.95691057394.89538924654.806787

Your reflection must include the learning you have gained about the topics of this
- 43. course and learning from the creation of your website. Review the Week Six Instructor Guidance to further support your response to this discussion. You may respond to this discussion in written form, or through a video and/or audio recording of yourself using the digital technology of your choosing. Initial Post: Create an initial post that addresses the following: · What new insights have you obtained about at-risk children and families overall? · What specific concepts have you learned that have left a more lasting impression or impact on you? How and/or why have these concepts impacted you more significantly than others? · What affirmations have you gained about your current or future role working with at-risk children and families from reflecting on your learning? Be sure to indicate what your professional focus is (e.g., education, early childhood education, family and community service, etc.). · How has the construction and review of others’ websites added value to your learning experience? Include challenges you may have experienced during the process and how you overcame them. Guided Response: Respond to a minimum of two peers. Make an effort to respond to someone in a similar professional field and one with a different professional focus. What similarities and differences did you discover between your peers’ and your own overall learning and lasting impressions? Provide specific feedback regarding the potential application of their learning to their professional practice. How does the value they gleaned from the website construction and sharing opportunities support and differ from your own reflection on this process? As mentioned in prior discussions, though two replies is the basic expectation, for deeper engagement and learning you are encouraged to provide responses to any comments or questions others have given to you to further the conversation while also giving you opportunities to demonstrate your content expertise, critical thinking, and real world experiences with the course topics.

Retrieved from https://redshelf.com · Use any of the chapters within the text to support enhancements made to any of the work included in your website as well as to inform your work on the specific group at risk you will select as a focus. Week Six Instructor Guidance Congratulations! And, welcome to the final week of EDU644: Child and Family Welfare! Please be sure to review the Week Six homepage for this course to see the specific learning outcomes for the week, the schedule overview, the required and recommended resources for the week, an introduction to the week, and a listing of the assessments for the week. Next, be sure to read this entire Instructor Guidance page. Overview Now is the time to reflect upon all you have learned and experienced in this course. You have formed a foundational concept of Child and Family Welfare including programming, policies, resources, and strategies to best assist families and children at risk. The past five weeks have addressed the implementation of your website as a tool to provide support for families and children at risk in your specialization. In Week Six you will prepare your final website project consisting of the requirements in the guidance. Also, you have the opportunity to reflect deeply on your learning from Weeks One through Five in the discussion thread. Intellectual Elaboration
- 45. Reflecting on the EDU644 Experience Over the last five weeks, we have focused on what it means to be at-risk and the impact being an individual or group at risk has on one’s ability to thrive. The ideas of team-based approaches, the usage of different resources (local, state, and federal), and the variety of populations at risk presented a complex, yet targeted mosaic of opportunities to support families and children at risk in order to improve their quality of living and student academic success. As you reflect on the numerous models, approaches, and strategies, think of how they can be best applied to the populations at risk in a way that builds long-term solutions. Why Reflect? Through reflective practice, a practitioner of any type can reframe a troubling situation so problem-solving actions may occur. Reflection is part of the learning process, whether a novice or an expert. It allows one to utilize a repertoire of understanding, images, and actions so as to respond most effectively (Merickel, 1998). Progressing into the Week 6 discussion and final project requires you to contemplate your learning experiences, course assessments, and concepts examined during the course and determine their impact on you. You will also relate your learning to that of your current or anticipated role working with children and families at risk. As both a learner and a professional, taking time to reflect upon your own practice as well as the behaviors and progress of your students or clients, is the first step in creating a road map toward finding solutions or applying improvements. Take time during Week Six to reflect on all you have learned and accomplished!
- 46. Assessment Guidance This section includes additional specific assistance for excelling in the discussions for Week Six beyond what is given with the instructions for the assessments. If you have questions about what is expected on any assessment for Week Six, contact your instructor using the Ask Your Instructor discussion before the due date. Discussion: Course Reflection This discussion is an opportunity for you to further demonstrate mastery with the five course learning outcomes, which are noted on the course Syllabus.The course reflection allows you to connect your ideas about families and children at risk by selecting the most relevant experiences and resources that can guide successful interventions. Select two or more aspects of the course that is relevant for you as well as for improving the lives of families and children. Consider your current or anticipated professional position. How do you anticipate your learning in this course will contribute to the work you do? This final discussion is the final opportunity for you to make your learning authentic! It also provides the chance to communicate with one another and gain additional insight to others’ learning, bringing up points you may not have considered in your own original response. Final Project: Creating a Web-Based Resource for a Population at Risk The final project is the culminating and comprehensive opportunity for you to demonstrate your mastery of the five course learning outcomes, which are noted on the course Syllabus. The activities and concepts in the course informed
- 47. you about populations at risk as well as strategies and resources to support these varied groups. Through your website research, you have gained models for the Final Project where you will demonstrate mastery of the five course learning outcomes by assuming the role of a professional working with individuals or families at risk. The assignment is to further refine and expand the website resource that describes this population and provides strategies and resources to support it. Specialization Pages Instructions: Create three additional pages in your website linked from the Homepage. Title the pages specifically for your selected group at risk as shown in Content Expectations for the assignment. The intention of the specialization pages is to present yourself as an “expert” in a particular group or sub-group, providing specific information and supports related to the group. You may select a specific group at risk from any of those studied during Weeks One through Five or another specific group at risk not specifically featured within the course. Many such groups are discussed in the Rubin text such as children with trauma related issues and PTSD, separation and attachment issues, and other groups such as homeless veterans, and Central American refugee children for which resources are recommended. It is recommend the required information be represented using a mix of both text and graphics such as charts, tables, and graphs. If a group previously covered during the course work is selected as your specialization, you must include information that expands upon what was already shared in the previously designed pages, showing more depth and different information than previously learned and shared. Also note in the Content Expectations the need to produce a text (written) version of your website. This is purely for accountability purposes during the evaluation process and to verify originality through Turn It In (TII) which cannot occur by reviewing the website alone.
