In this paper, we present our analysis of 92 fourth graders' digital story projects completed in LaPlaya, a Scratch-like programming environment. Projects were analyzed for the way that students programmed the start of the story, and if the program integrated user-centered design by providing instruction to the user on how to interact with the digital story. We found that fourth grade students rarely used user-centered design while creating digital stories in our block-based programming environment. Without explicit instruction, the demands of learning programming and simultaneously programming for an abstract user may be too cognitively demanding for the average fourth grader.

This paper describes the ScratchJr research project, a collaboration between Tufts University's Developmental Technologies Research Group, MIT's Lifelong Kindergarten Group, and the Playful Invention Company. Over the past five years, dozens of ScratchJr prototypes have been designed and studied with over 300 K-2ndgrade students, teachers and parents. ScratchJr allows children ages 5 to 7 years to explore concepts of computer programming and digital content creation in a safe and fun environment. This paper describes the progression of major prototypes leading to the current public version, as well as the educational resources developed for use with ScratchJr. Future directions and educational implications are also discussed.

Cílem této diplomové práce je návrh a realizace uživatelského rozhraní v prostředí NI LabVIEW pro konstrukčně zdokonalený prototyp biomechanického testovacího přístroje realizovaného v rámci spolupráce ÚMTMB a ÚAI. Jedná se o přístroj zkoumající vlastnosti páteřních obratlů. Hlavním úkolem práce je realizovat software, který umožní plánovat, spouštět a zaznamenávat dlouhodobé experimenty na tomto zařízení. Práce je členěna na část teoretickou a praktickou. První z nich se zabývá popisem testovacího přístroje, dále jsou shrnuty veškeré kladené požadavky ze strany uživatelů, následuje popis použitých nástrojů pro realizaci software v prostředí NI LabVIEW 8.6. Praktická část se zabývá samotným návrhem a realizací vytvořeného software pro plánování a řízení experimentů vyvinutého v prostředí NI LabVIEW 8.6 a jeho následným testováním. Závěrem je rozebrán vznik a řešení stěžejních problémů vzniklých při realizaci.

The multiplication algorithms taught to elementary students are made to help students find answers quickly, but why the algorithm works and how it relates to multiplication is not widely known. For example, one intuitive meaning of multiplication is that of iterated, or, repeated, addition. In this paper, we look at the ways a visual, block-based, programming activity uses the concept of iteration to help second-graders learn multiplication. The results of the study observing second-grade students use visual programming and iteration to setup and solve multiplication story problems. We found that generally students enjoyed these activities and found them helpful during the learning process.

The Medical Exploration Toolkit: An Efficient Support for Visual Computing in Surgical Planning and Training

IEEE TRANSACTIONS ON VISUALIZATION AND COMPUTER GRAPHICS 2010年第1期16卷 133-146页

Application development is often guided by the usage of software libraries and toolkits. For medical applications, the toolkits currently available focus on image analysis and volume rendering. Advanced interactive visualizations and user interface issues are not adequately supported. Hence, we present a toolkit for application development in the field of medical intervention planning, training, and presentation-theMEDICALEXPLORATIONTOOLKIT (METK). The METK is based on the rapid prototyping platform MeVisLab and offers a large variety of facilities for an easy and efficient application development process. We present dedicated techniques for advanced medical visualizations, exploration, standardized documentation, and interface widgets for common tasks. These include, e. g., advanced animation facilities, viewpoint selection, several illustrative rendering techniques, and new techniques for object selection in 3D surface models. No extended programming skills are needed for application building, since a graphical programming approach can be used. The toolkit is freely available and well documented to facilitate the use and extension of the toolkit.

The Impact of Blended Learning on LabVIEW Certification Test Scores-A Case Study

引用

INTERNATIONAL JOURNAL OF ENGINEERING EDUCATION 2014年第1期30卷 263-271页

作者： Ugurlu, Yuecel Univ Tokyo Dept Creat Informat Bunkyo Ku Tokyo 1138656 Japan

This paper introduces an efficient blended learning approach to teaching LabVIEW-based graphical programming and examines the impact of the proposed approach on LabVIEW certification test scores. A traditional course was blended with e-learning technology to boost the programming skills of students and to better teach advanced topics. The need to complete student-designed projects and a certification exam encouraged the students to use the e-learning system outside of class, in addition to their work in regular classroom time. Individual data analysis and student survey results showed that e-learning was mainly used as a tool to help prepare for the certification test. In our case study, students who used the e-learning system achieved certification test results almost 40% higher than those who only had face-to-face learning experiences.

APPLICATION OF PETRI NETS TO SEQUENCE CONTROL

IEICE TRANSACTIONS ON FUNDAMENTALS OF ELECTRONICS COMMUNICATIONS AND COMPUTER SCIENCES 1993年第10期E76A卷 1598-1606页

We describe K-NET, a support system for development of sequence control programs. The K-NET description model is based on the colored Petri net and timed Petri net. K-NET concisely expresses sequence control flow including synchronization, interlock and concurrence, and provides high-level data processing by being combined with a conventional procedural language. K-NET has an editor, simulator, generator, reporter and monitor to support the control program development procedure ranging from basic and detail design to programming and testing. We have added a new function to K-NET so it assists development of control programs for programmable controllers, and have applied it to an automatic bolt supplying system. The operation results are satisfactory.

Linear Interval Approximation of Sensor Characteristics with Inflection Points

SENSORS 2023年第6期23卷 2933-2933页

The popularity of smart sensors and the Internet of Things (IoT) is growing in various fields and applications. Both collect and transfer data to networks. However, due to limited resources, deploying IoT in real-world applications can be challenging. Most of the algorithmic solutions proposed so far to address these challenges were based on linear interval approximations and were developed for resource-constrained microcontroller architectures, i.e., they need buffering of the sensor data and either have a runtime dependency on the segment length or require the sensor inverse response to be analytically known in advance. Our present work proposed a new algorithm for the piecewise-linear approximation of differentiable sensor characteristics with varying algebraic curvature, maintaining the low fixed computational complexity as well as reduced memory requirements, as demonstrated in a test concerning the linearization of the inverse sensor characteristic of type K thermocouple. As before, our error-minimization approach solved the two problems of finding the inverse sensor characteristic and its linearization simultaneously while minimizing the number of points needed to support the characteristic.

Assembly: A Web-Based Multi-Robot programming and Simulation Tool

引用

IFAC-PapersOnLine 2022年第2期55卷 313-318页

作者： Tudor B. Ionescu Vienna University of Technology (TU Wien) Vienna Austria

This paper introduces a novel, open-source, web-based, end-user programming and simulation environment for multi-robot cells, called Assembly. The target audience of this tool includes people with little or no programming experience, both in industrial and non-industrial contexts. The focus of the paper will be on the web-based technologies and architecture supporting multi-robot simulation and dynamic toolpath planning with obstacle avoidance in multi-robot scenarios. The main features of the tool and the technologies that enable them are introduced and its applicability is evaluated on the basis of an exemplar industrial application.
