    PVC external lubricant is a kind of additive used in PVC processing, the main function is to form a lubricant film between PVC and processing equipment, reduce the direct contact between PVC and equipment, reduce friction and wear, and improve processing performance. Compared with the internal lubricant, our H-74 external lubricant is especially suitable for the processing of soft/hard PVC granules, transparent sheets and shrink films, which has less influence on the melt fluidity of PVC, and also reduces the equilibrium torque and strengthens the demoulding effect.

    Hairuite manufactures external lubricant for PVC. Our H-74 external lubricant is ideal for soft/hard PVC granules, transparent sheets, and shrink films. Minimally affect PVC melt fluidity, reduce equilibrium torque, and enhance demoulding.

      • Good teachers must know their subjects well, but having doctoral-level knowledge of Freudian interpretations of Victorian literature, for example, doesn't really improve someone's ability to teach language arts to 8th graders.

      • They found that although content knowledge is essential, teachers who also possess strong pedagogical content knowledge are more effective than those with content knowledge alone.

      • common metrics for hiring and rewarding teachers are only weakly linked to student success.
      • Traditional licensure or credentials.
      • "little rigorous evidence that [teacher certification] is systematically related to student achievement"
      • Yet the study detected no before-and-after effects—that is, teachers appeared no more effective after undergoing the grueling certification process than before it (Clotfelter, Ladd, & Vigdor, 2007).
      • Advanced degrees.

      Reinventing the Big Test: The Challenge of Authentic Assessment | Edutopia - 0 views

      • Equally worrisome is that today's assessments emphasize narrow skill sets such as geometry and grammar, and omit huge chunks of what educators and business leaders say is essential for modern students to learn: creative thinking, problem solving, cooperative teamwork, technological literacy, and self-direction. Yet because NCLB has made accountability tests the tail that wags the dog of the whole education system -- threatening remediation and state takeover for schools that fall short -- what's not tested often isn't taught.

          The disconnect between high-stakes tests and the future we are preparing our kids for
      • many experts tout the Programme for International Student Assessment (PISA) exam for its challenging, open-ended questions on practical topics, such as climate change or the pros and cons of graffiti. Even more advanced models, some using computer simulations, will become available in a few years -- and none too soon.
      • static problem, for instance, would ask test takers to say from memory how to save a certain endangered bird species. A dynamic assessment (in a real example from Bransford's lab) asks students to use available resources to learn what it would take to prevent the white-eyed vireo from becoming endangered. This is a novel question that demands students independently dig for information and know enough to ask the right questions to reach a solution.

      • The British government has created a computer-literacy test that challenges teens to solve realistic problems (how to control crowds at a soccer match, for instance) using online resources. The more sophisticated these tools become, and the more adeptly test makers use them, the better assessment will be.

        Unit of work for Second Classroom Project. Students undertake a PBL task using Skoolaborate (http://www.skoolaborate.com) as thier presentation tool. Uses Group Ning for journal and student blog, Group FlickR to document progress. Project could also work using Google Sketch Up and Voice Thread. Final project solutions will be rezzed in Second Life on the Island of Jokadia for external viewing by PBL teachers. Time frame 6 weeks. See the Ning at http://secondclassroom.ning.com for project progress and contact information. Project first delivered April 2008.

        Project-based learning offers promise as an instructional method that affords authentic learning tasks grounded in the personal interests of learners. While previous research has presented results of learning gains, motivations and teacher experiences, still limited empirical research has presented the student perspective in project-based learning. This research sought to explore how learners created projects. Using a case study design and five purposively selected participants from eighth grade geography, five themes emerged: (1) internal influences, (2) external influences, (3) beliefs about projects, (4) tools for technology-rich environments, and (5) learning outcomes and products. The first four themes describe influences to shape the fifth theme, learning products. The term learning products was used to describe both the learning garnered by the participants and the learning artifacts the participants produced as part of the instructional unit. Implications for practice and future research are considered.
