Developing a teaching chatbot for learning tools and equipment in technology classrooms

Using and applying tools and equipment for designing and building projects has always been indispensable in living technology classrooms. However, students must be aware of their proper use to avoid mistakes and safety concerns. In recent years, chatbots have been widely used in various fields, offering instant, interactive responses, and their application in educational contexts has also increased rapidly. Therefore, this study developed a chatbot for LINE, a popular messaging app in Asia, for teaching standard hand tools and equipment in living technology classrooms at secondary schools. This chatbot covered (1) measuring tools, (2) hand tools, (3) power tools and equipment, and others. A total of 49 tools and pieces of equipment were included. The instructional content for each consisted of (1) instructions, (2) operating procedures and skills, and (3) troubleshooting and maintenance. The user interface adopted point-and-click forms and graphical menus to quickly guide users searching for specific information. In addition, users can enter relevant keywords and the chatbot will answer the corresponding content. The chatbot is expected to solve student questions more efficiently and assist teachers, improving the effectiveness and convenience of these hands-on lessons

Why a local moment induces an antiferromagnetic ordering: An RVB picture

Based on a Gutzwiller projected BCS wavefunction, it is shown that a local S=1/2 moment is present around a vacancy site (zinc impurity) in a form of staggered magnetic moments, which is a direct consequence of the short-ranged resonating-valence-bond (RVB) pairing in the spin background.Comment: 4 pages, 3 figure

Quantum Algorithm for Solving Quadratic Nonlinear System of Equations

High-dimensional nonlinear system of equations that appears in all kinds of fields is difficult to be solved on a classical computer, we present an efficient quantum algorithm for solving $n$-dimensional quadratic nonlinear system of equations. Our algorithm embeds the equations into a finite-dimensional system of linear equations with homotopy perturbation method and a linearization technique, then we solve the linear equations with quantum linear system solver and obtain a state which is $\epsilon$-close to the normalized exact solution of the original nonlinear equations with success probability $\Omega(1)$. The complexity of our algorithm is $O(\rm{poly}(\rm{log}(n/\epsilon)))$, which provides an exponential improvement over the optimal classical algorithm in dimension $n$.Comment: 9 pages; Modify the format error of tex source fil

Acceptance Of Qr Code In Taiwan: An Extension Of The Technology Acceptance Model

The development and application of QR code is quite advanced in Japan and Korea; in contrast, at the time when the QR code was introduced in Taiwan, lack of mobile phone support and the limited applications of QR code meant that it was not immediately popularized. In recent years, the growing popularity of smart phones has enhanced the various applications of QR code, not only providing the information to the user, but also performing navigation, marketing and ticketing functions, to name a few. This study is based on the Technology Acceptance Model, with Social Influence, Facilitating Conditions, Awareness Knowledge, Operation Knowledge and Price as the usage factors, and by verifying the structural modelling through public surveys and analyzing the importance of the Acceptance Model and other influences of users in Taiwan as the driving factors in incorporating QR code applications in the government, telecommunication carrier and business spheres
