Abstract

This project was designed to incorporate maker education into the final-year research project of the undergraduate chemistry program. It involves taking a project from concept to prototype through project-based learning, emphasizing hands-on learning experiences to solve real-world problems. A final-year undergraduate chemistry student was involved in this work. This student identified a problem through a literature review, designed the necessary equipment, built the prototype to address the identified problem, and assessed its performance using statistical methods. The student successfully developed a low-cost autotitrator using Arduino Uno-compatible microcontrollers, a pH sensor, an open-source PLX-DAQ data acquisition system, 3D printing technology, and various electronic components for determining the percentage of total acidity in fruit juices. Engaging in this project significantly enhanced the student’s technical skills and developed problem-solving abilities, critical thinking, and creativity, which are essential for the future workforce. Additionally, this project enables chemistry students to gain a deeper understanding of the hardware and equipment development process. Moreover, it trains students in utilizing open-source software and identifying cost-effective solutions for building prototypes to solve real-world problems. The concept of this project is adaptable and can be applied to train students in designing and building various chemistry-related equipment.

将创客教育融入本科化学专业研究项目:基于arduino的低成本3D打印自动滴定仪
本项目旨在将创客教育纳入本科化学专业的最后一年研究项目。它包括通过基于项目的学习,将项目从概念到原型,强调动手学习经验来解决现实世界的问题。一位大四的化学专业学生参与了这项工作。该学生通过查阅文献发现问题,设计必要的设备,构建原型来解决发现的问题,并使用统计方法评估其性能。该学生成功开发了一个低成本的自动滴定仪,使用Arduino不兼容微控制器、pH传感器、开源PLX-DAQ数据采集系统、3D打印技术和各种电子元件来确定果汁中总酸度的百分比。参与这个项目大大提高了学生的技术技能,培养了解决问题的能力,批判性思维和创造力,这些都是未来劳动力所必需的。此外,这个项目使化学学生对硬件和设备的开发过程有了更深入的了解。此外,它还训练学生利用开源软件,并为构建原型来解决现实世界的问题确定具有成本效益的解决方案。这个项目的概念是适应性强的,可以用来训练学生设计和建造各种化学相关的设备。

期刊介绍: The Journal of Chemical Education is the official journal of the Division of Chemical Education of the American Chemical Society, co-published with the American Chemical Society Publications Division. Launched in 1924, the Journal of Chemical Education is the world’s premier chemical education journal. The Journal publishes peer-reviewed articles and related information as a resource to those in the field of chemical education and to those institutions that serve them. JCE typically addresses chemical content, activities, laboratory experiments, instructional methods, and pedagogies. The Journal serves as a means of communication among people across the world who are interested in the teaching and learning of chemistry. This includes instructors of chemistry from middle school through graduate school, professional staff who support these teaching activities, as well as some scientists in commerce, industry, and government.
