The memory space: Exploring future uses of Web 2.0 and mobile internet through design interventions.

The QuVis Quantum Mechanics Visualization project aims to address challenges of quantum mechanics instruction through the development of interactive simulations for the learning and teaching of quantum mechanics. In this article, we describe evaluation of simulations focusing on two-level systems developed as part of the Institute of Physics Quantum Physics resources. Simulations are research-based and have been iteratively refined using student feedback in individual observation sessions and in-class trials. We give evidence that these simulations are helping students learn quantum mechanics concepts at both the introductory and advanced undergraduate level, and that students perceive simulations to be beneficial to their learning.Comment: 15 pages, 5 figures, 1 table; accepted for publication in the American Journal of Physic

Model Visualization of Atomic Quantum Numbers Three Dimensional on Physics Lesson in Class XII Science High School (SMAN 10) Padang West Sumatra Indonesia

Physics as a science is a major corner stone in the development of technology that physical theories require a high degree of precision. Knowledge of physics consists of many of the concepts and principles that are generally abstract. Physics is a subject that requires a relatively high intellect so most students have difficulty studying. Many difficulties faced by most students is the interpretation of various concepts and principles of physics because students are required to be able to interpret the knowledge of physics and its application in daily life properly and not vague or ambiguous. This situation is exacerbated by the use of learning methods that are less precise physics.This research aims to the problems of physics concepts and principles of quantum numbers of atomic models that abstract becomes real and can be perceived by students as a learning experience guiding students visualize models with atomic quantum numbers in three dimensions in the learning process .The results of the study are students better understand the concepts and principles of three dimensional model of the atom, and can put electron configuration in the electron orbit in accordance with the rules of quantum numbers, Pauli principle prohibition, Hund and Aufbau. From the questionnaire given to the students and observation and test show a good understanding of the concept occurred with an average value of 92.45 and a good learning activity occurs in the students.

An Active Learning Computer-Based Teaching Tool for Enhancing Students’ Learning and Visualization Skills in Electromagnetics

Electromagnetic theoretical concepts, which are represented mathematically, are usually challenging to grasp by students. In this study, we explore an interactive technology-based teaching tool to develop further students’ mastery of electromagnetic concepts through learning development and visualization of electromagnetic problems. This visualization of the problems will help students analyse, evaluate, and draw conclusions of the impact of electromagnetic-related problems in real-life. The simulation tool in this study is based on a MATLAB toolbox package, in which partial-differential equations (PDE) solver is the core engine. In this paper, we will also provide a step-by-step guide on the use of such an interactive computer-aided tool so that it can be a great self-guide tool for beginners in the field of physics and a first-level introductory course in electromagnetism. This study will focus mainly on one classical electrostatic problem that is a challenge to students to visualize, analyze and evaluate. Based on students feedback by the end of the course, 80% of students' population are more comfortablewith the introduced interactive learning tool.

Changes in Students' Cognitive Structure on the Concept of Diffraction and Light Interference Using PhET Virtual Simulation

The concept of diffraction and interference of light is one of the abstract concepts of physics. The process of light diffraction and interference occurs in the abstract. Learning about diffraction and light interference requires media that represent the events. Cognitive structures can represent the quality of students' understanding. Learning Physics is easier to understand through direct experience in the form of practicum. Abstract Physics concepts will be easier to learn with the appropriate visualization. One of the virtual practicums' media uses PhET virtual simulations to improve students' cognitive structure is measured using concept map questions and supported by description questions. The purpose of this research is to increase the cognitive structure of students by using PhET. This research is quantitative research and the experimental design used the experiment method. There are three groups in the experiment, that is a virtual simulation, a real practicum as an experiment class, and a control class. The results of the one-way ANOVA test on the concept map questions showed a significance value (p) 0.05, meaning that there were differences in cognitive structure between groups. The significance value (p) between the virtual simulation group and the real practicum group was 0.014, while the significance value between the virtual simulation group and the control class was 0.00, meaning that there was a significant difference in learning effectiveness between groups. Based on the data of the research concluded that physics learning assisted by virtual simulations can develop students' cognitive structures on the concepts of diffraction and light interference

WavePacket: A Matlab package for numerical quantum dynamics. II: Open quantum systems, optimal control, and model reduction

WavePacket is an open-source program package for numeric simulations in quantum dynamics. It can solve time-independent or time-dependent linear Schr\"odinger and Liouville-von Neumann-equations in one or more dimensions. Also coupled equations can be treated, which allows, e.g., to simulate molecular quantum dynamics beyond the Born-Oppenheimer approximation. Optionally accounting for the interaction with external electric fields within the semi-classical dipole approximation, WavePacket can be used to simulate experiments involving tailored light pulses in photo-induced physics or chemistry. Being highly versatile and offering visualization of quantum dynamics 'on the fly', WavePacket is well suited for teaching or research projects in atomic, molecular and optical physics as well as in physical or theoretical chemistry. Building on the previous Part I which dealt with closed quantum systems and discrete variable representations, the present Part II focuses on the dynamics of open quantum systems, with Lindblad operators modeling dissipation and dephasing. This part also describes the WavePacket function for optimal control of quantum dynamics, building on rapid monotonically convergent iteration methods. Furthermore, two different approaches to dimension reduction implemented in WavePacket are documented here. In the first one, a balancing transformation based on the concepts of controllability and observability Gramians is used to identify states that are neither well controllable nor well observable. Those states are either truncated or averaged out. In the other approach, the H2-error for a given reduced dimensionality is minimized by H2 optimal model reduction techniques, utilizing a bilinear iterative rational Krylov algorithm
