Quantifying critical thinking: Development and validation of the Physics Lab Inventory of Critical thinking (PLIC)

Introductory physics lab instruction is undergoing a transformation, with increasing emphasis on developing experimentation and critical thinking skills. These changes present a need for standardized assessment instruments to determine the degree to which students develop these skills through instructional labs. In this article, we present the development and validation of the Physics Lab Inventory of Critical thinking (PLIC). We define critical thinking as the ability to use data and evidence to decide what to trust and what to do. The PLIC is a 10-question, closed-response assessment that probes student critical thinking skills in the context of physics experimentation. Using interviews and data from 5584 students at 29 institutions, we demonstrate, through qualitative and quantitative means, the validity and reliability of the instrument at measuring student critical thinking skills. This establishes a valuable new assessment instrument for instructional labs.Comment: 16 pages, 4 figure

Takagi-Sugeno fuzzy perpose as speed controller in indirect field oriented control of induction motor drive

This paper deal with the problem in speed controller for Indirect Field Oriented Control of Induction Motor. The problem cause decrease performance of Induction Motor where it widely used in high-performance applications. In order decrease the fault of speed induction motor, Takagi- Sugeno type Fuzzy logic control is used as the speed controller. For this, a model of indirect field oriented control of induction motor is built and simulating using MATLAB simulink. Secondly, error of speed and derivative error as the input and change of torque command as the output for speed control is applied in simulation. Lastly, from the simulation result overshoot is zero persent, rise time is 0.4s and settling time is 0.4s. The important data is steady state error is 0.01 percent show that the speed can follow reference speed. From that simulation result illustrate the effectiveness of the proposed approach

Trialing project-based learning in a new EAP ESP course: A collaborative reflective practice of three college English teachers

Currently in many Chinese universities, the traditional College English course is facing the risk of being ‘marginalized’, replaced or even removed, and many hours previously allocated to the course are now being taken by EAP or ESP. At X University in northern China, a curriculum reform as such is taking place, as a result of which a new course has been created called ‘xue ke’ English. Despite the fact that ‘xue ke’ means subject literally, the course designer has made it clear that subject content is not the target, nor is the course the same as EAP or ESP. This curriculum initiative, while possibly having been justified with a rationale of some kind (e.g. to meet with changing social and/or academic needs of students and/or institutions), this is posing a great challenge for, as well as considerable pressure on, a number of College English teachers who have taught this single course for almost their entire teaching career. In such a context, three teachers formed a peer support group in Semester One this year, to work collaboratively co-tackling the challenge, and they chose Project-Based Learning (PBL) for the new course. This presentation will report on the implementation of this project, including the overall designing, operational procedure, and the teachers’ reflections. Based on discussion, pre-agreement was reached on the purpose and manner of collaboration as offering peer support for more effective teaching and learning and fulfilling and pleasant professional development. A WeChat group was set up as the chief platform for messaging, idea-sharing, and resource-exchanging. Physical meetings were supplementary, with sound agenda but flexible time, and venues. Mosoteach cloud class (lan mo yun ban ke) was established as a tool for virtual learning, employed both in and after class. Discussions were held at the beginning of the semester which determined only brief outlines for PBL implementation and allowed space for everyone to autonomously explore in their own way. Constant further discussions followed, which generated a great deal of opportunities for peer learning and lesson plan modifications. A reflective journal, in a greater or lesser detailed manner, was also kept by each teacher to record the journey of the collaboration. At the end of the semester, it was commonly recognized that, although challenges existed, the collaboration was overall a success and they were all willing to continue with it and endeavor to refine it to be a more professional and productive approach

Information Literacy Instruction for Upper-Year Undergraduate Students: A Stratified Course-Integrated Approach

Undergraduate students face many potential barriers to learning about the process of conducting research. Information literacy instruction provided through faculty-librarian collaboration in an effort to expand the abilities of the “novice researcher” can ease the experience of undergraduate students. In addition, information literacy instruction may invoke increased student participation in the scholarly discourse of their chosen discipline. The implementation of a stratified course-integrated approach may be particularly valuable to upper-level undergraduates in preparation for completing a thesis or other culminating project in their final year of study. This claim is examined within the context of an instruction session observed as a component of a third-year undergraduate Materials Science and Engineering course

Education innovation through material innovation in primary education : the grow-it-yourself workshop

In recent years more STEM (Science, Technology, Engineering and Mathematics) topics have been incorporated in mainstream public education. Although the benefits of STEM instruction are broadly recognised in secondary school curricula, STEM topics in primary education are rather limited, leaving a gap in manipulative skills building and in preparation processes for the next school level. This paper reflects on the outcomes of a design workshop attended by 12 primary school students (9 to 12 years old) in Belgium. Mycelium, a fungi-based natural material now used in innovative sustainable applications, served as a means to introduce early learners engineering basics through self-made learning tools. Students grew their own 3-D structures to build a 'Grow-It-Yourself biodegradable playground using mycelium as a primary source. The paper stems from an in-progress research that investigates the opportunities of how mycelium as a material innovation can be used as a medium to create innovation in primary education through a learning-by-design approach. Reflections on the workshop's instructional guidelines are included along with an extension of the call for support for primary school teachers delivering STEM topics in their classes

Preparing the Future Workforce: Science, Technology, Engineering and Math (STEM) Policy in K12 Education in Wisconsin

Last December, the Science, Technology, Engineering, and Mathematics (STEM) Education Coalition - a national organization of more than 600 groups representing knowledge workers, educators, scientists, engineers, and technicians wrote to President-elect Obama urging him to "not lose sight of the critical role that STEM education plays in enabling the United States to remain the economic and technological leader of the 21st century global marketplace." While that imperative appears to have resonated in Washington, has it and should it resonate in Madison? This report attempts to answer that question by examining the extent to which STEM skills are a necessity for tomorrow's Wisconsin workforce, whether our schools are preparing students to be STEM-savvy workers, and where STEM falls in the state's list of educational priorities
