STEM-based learning systems have become commonplace in developed countries today. Students who are taught STEM are expected to be able to realize their imagination and creativity from an early age by directly implementing the basic knowledge gained during school into a real product so that the level of students' understanding of a science can be deep and lasting. Early habituation for schoolage students to get acquainted and plunge into direct practice related to STEM is their main capital in facing future challenges that require adaptation to many new things and a race for creativity that is able to produce innovative products of commercial value and be utilized by mankind. The product resulting from this study received a very positive response from several students who were respondents, although of course, improvements were still needed in terms of the hardware and software that were built.
如今,基于stem的学习系统在发达国家已经司空见惯。通过将在学校所学的基础知识直接应用到实际产品中,期望STEM教育的学生从小就能发挥他们的想象力和创造力,从而使学生对一门科学的理解水平能够深入而持久。学龄学生的早期习惯是了解并投入到与STEM相关的直接实践中,这是他们面对未来挑战的主要资本,这些挑战需要适应许多新事物,以及能够产生具有商业价值并为人类所利用的创新产品的创造力竞赛。从这项研究中产生的产品得到了一些学生的非常积极的回应,尽管当然,在硬件和软件方面仍然需要改进。

Experiments on nuclear physics with precise measurements are exciting things to do. The experiment supports the STEM approach based on real experiments and especially if it is low-cost equipment. In this study, a preliminary study was conducted on the proton precession magnetometer (PPM) design, which will be used as a teaching aid for STEM learning to explore the atomic nucleus and as a magnetometer to determine the strength of the earth's magnetic field accurately. The PPM signal is susceptible to changes in the external magnetic field so that external magnetic disturbances such as electric currents and ferromagnetic materials in the building produce noise. So the measurements are carried out outside the building. The sensor uses two coils that are polarized opposite each other to eliminate the noise from the outside. In addition, analog filtering is also designed in a bandpass filter only to pass the desired frequency range. Since the PPM signal is tiny, the coil is coupled with a suitable capacitor to amplify the signal radiated by the protons through an inductor-capacitor resonance effect at the desired target frequency. Signal PPM measurement results in the time domain can be displayed, although visually, it is difficult to recognize because it is immersed in noise. However, when heard with the human ear, the distinctive sound of the PPM signal will be clear for about 3 seconds after applying polarizing current to the coil. Waves in the time domain can be converted into the frequency domain using audacity 3.0.2 software. The peak frequency obtained is 1914 Hz. Based on the values of these frequencies, based on the Larmor formula, the value of the earth's magnetic field obtained is 44.97 uT.
具有精确测量的核物理实验是令人兴奋的事情。该实验支持基于真实实验的STEM方法,特别是如果它是低成本的设备。本研究对质子进动磁强计(PPM)的设计进行了初步研究,该设计将作为STEM学习的教具来探索原子核,并作为磁强计来精确测定地球磁场的强度。PPM信号易受外部磁场变化的影响,使建筑物内的电流、铁磁性材料等外部磁干扰产生噪声。所以测量是在大楼外进行的。该传感器使用两个相互极化的线圈来消除来自外部的噪声。此外,还在带通滤波器中设计了模拟滤波,仅使其通过所需的频率范围。由于PPM信号很小,线圈与合适的电容器耦合,通过电感-电容器谐振效应在期望的目标频率上放大质子辐射的信号。信号PPM在时域内的测量结果虽然可以直观地显示出来,但由于沉浸在噪声中,难以识别。然而,当用人耳听到时,在对线圈施加极化电流后,PPM信号的独特声音将清晰约3秒。使用audacity 3.0.2软件可以将时域的波转换为频域。得到的峰值频率为1914 Hz。根据这些频率的值,根据拉莫尔公式,得到地球磁场的值为44.97 uT。

School closure during the pandemic requires teachers to integrate digital technology for teaching and learning. Therefore, it is necessary to examine mathematics teachers' digital literacy. The purpose of this study was to examine Indonesian secondary school teachers' digital literacy and investigate if digital literacy levels are significantly different in terms of gender, teaching experience, the level of schools, and teacher level of education. We conducted a quantitative study with a cross-sectional survey design. Data were collected from 232 secondary school teachers and analyzed by ANOVA. This study suggests that, to some extent, demographic variables do not play a significant role in teachers' level of teachers' digital literacy. It was found that, among demographic background variables examined in this study, only teachers' levels of education have a significant role in the level of digital literacy. It indicates that researchers and practitioners should take teachers' education level into account when they design and implement professional development on digital literacy.
大流行期间学校关闭要求教师将数字技术用于教学和学习。因此,有必要对数学教师的数字素养进行考察。本研究的目的是考察印尼中学教师的数字素养,并调查数字素养水平是否在性别、教学经验、学校水平和教师教育水平方面存在显著差异。我们采用横断面调查设计进行了定量研究。对232名中学教师进行问卷调查,采用方差分析方法进行分析。本研究表明,在一定程度上,人口统计变量对教师数字素养水平的影响并不显著。研究发现,在本研究考察的人口统计背景变量中,只有教师的教育水平对数字素养水平有显著影响。这表明研究者和实践者在设计和实施数字素养专业发展时应考虑教师的教育水平。

2D resistivity models of magnetotelluric data had been simulated for studying magma activity within volcanic conduits. The simulated models can be used to understand the pre-eruption of volcanic behavior based on the change of resistivity responses measured on an active volcano. Four resistivity models of conduit states have been modeled using REBOCC MT forward modeling code. The models include a conduit with empty magma, the magma starts to accumulate in the conduit, the magma rises, and the conduit full of magma. The resistivity value of the empty conduit and the magma material was 10 Ohm-m and 50.000 Ohm-m, respectively. While the conduit is located within a volcano composed of three resistivity layers, i.e., 100 Ohm-m, 400 Ohm-m, and 1000 Ohm-m from the top to the bottom. The synthetic data responses generated by each model were used to analyze each state. The calculated transfer function of magnetotelluric data includes apparent resistivity and phase for TE-mode. Each data set were calculated in range of period 0.001, 0.01, 0.1, 10, 100, 1000 s. The results showed that apparent resistivity responses increase with increasing the magma height in the conduit. The simulated models can be used to predict the height of the magma before it would be reached the surface as a precursor of a volcanic eruption.
为研究火山导管内岩浆活动,对大地电磁资料的二维电阻率模型进行了模拟。模拟模型可以根据在活火山上测量到的电阻率响应的变化来了解火山喷发前的行为。利用REBOCC MT正演模拟程序对管道状态的4种电阻率模型进行了模拟。这些模型包括一个有空岩浆的管道,岩浆开始在管道中积聚,岩浆上升,以及充满岩浆的管道。空导管的电阻率为10 ω -m,岩浆物质的电阻率为5 ω -m。而管道位于火山内,火山由三个电阻率层组成,从上到下分别为100欧姆、400欧姆和1000欧姆。每个模型生成的综合数据响应用于分析每个状态。计算的大地电磁资料传递函数包括te模式下的视电阻率和相位。每个数据集在0.001、0.01、0.1、10、100、1000 s的范围内进行计算。结果表明,视电阻率响应随岩浆高度的增加而增大。模拟的模型可以用来预测岩浆到达地表之前的高度,作为火山爆发的前兆。

It is necessary to develop students to become lifelong learning of science, technology, engineering, and mathematics to meet the challenges in the 21st century. Therefore, the STEM research center of Universitas Syiah Kuala in collaboration with other stakeholders in education, namely government, industry, public, and media has launched the Science, Technology, Engineering, Mathematics, and Character (STEMC) learning approach. There are six aspects to be developed through the STEMC approach: critical thinking, creativity, communication, collaboration, computational thinking, and characters. In general, the nature of STEMC is not only a process of transferring knowledge from teachers to students but also an effort to build students' character. STEMC approach is designed to improve students' scientific abilities, motivation, and perseverance. It means that every phase of learning is designing to support students' intellectual and emotional growth. This paper aims to address what has been done at the STEM Research Center of Universitas Syiah Kuala and the plan for integrating STEMC in Indonesia. It provides an overview of some projects that have been conducted, such as the development of STEMC modules for senior high schools and collaboration with State-Owned Enterprises (SOEs) in teacher professional development programs. In addition, this paper also highlights the STEM center's plan to implement STEMC in Indonesia
为了迎接21世纪的挑战,有必要培养学生成为终身学习科学、技术、工程和数学的人。因此,吉隆坡赛亚大学的STEM研究中心与教育领域的其他利益相关者,即政府、行业、公众和媒体合作,推出了科学、技术、工程、数学和字符(STEMC)学习方法。通过STEMC方法有六个方面需要发展:批判性思维、创造力、沟通、协作、计算思维和性格。总的来说,STEMC的本质不仅是教师向学生传授知识的过程,而且是努力塑造学生性格的过程。STEMC方法旨在提高学生的科学能力、动力和毅力。这意味着学习的每个阶段都是为了支持学生的智力和情感发展而设计的。这篇论文的目的是解决在Syiah Kuala Universitas的STEM研究中心所做的事情以及在印度尼西亚整合STEMC的计划。它概述了已经开展的一些项目,例如为高中开发STEMC模块以及与国有企业合作开展教师专业发展计划。此外,本文还重点介绍了STEM中心在印尼实施STEMC的计划

This research aims to: 1) use lessons from knowledge, skills, and experience gained from a lecturer who produced online teaching materials for PSU MOOC; and, 2) reflect the participation of volunteer students and participating entrepreneurs in the production of online teaching materials for PSU MOOC. The research methodology used was Classroom Action Research. In this current study, the development of a subject, namely Entrepreneurs and New Venture Creation, during May-August, 2021 is purposively selected as a case study. Regarding the case study, the authors intend to apply this methodology to determine and portray the overall learning and experiences gained from the PSU MOOC development throughout the three phases. During the planning phase, knowledge of MOOCs, skills, and criteria for MOOCs should be identified. Advisory is compulsory for inexperienced lecturers in order to understand the criteria and learn some skills. Group work is mandatory to gain some skills to accomplish the process in time. The aims of the curriculum should be established. In a second phase (the development phase), the curriculum design, as well as the production plan, should be aligned with course learning objectives. Then, the proper assessment should be established with the aim to ensure that the learners can achieve the learning objectives. In the execution phase as a third phase, the communication plan is to assure that course will be able to reach the target audience. The evaluation process is to gain feedback to improve the quality of the course. The development of the subject Entrepreneurs and New Venture Creation could be a prime example of containing lessons that could be learned by other lecturers as they create their online MOOC courses.
本研究旨在:1)利用从一位为PSU MOOC制作在线教材的讲师那里获得的知识、技能和经验;2)反映志愿者学生和参与企业家参与PSU MOOC在线教材制作的情况。使用的研究方法是课堂行动研究。在本研究中,有意选择2021年5月至8月期间企业家与新创企业这一主题的发展作为案例研究。在案例研究中,作者打算运用这种方法来确定和描述PSU MOOC在三个阶段的整体学习和经验。在规划阶段,应该确定mooc的知识、技能和标准。对于没有经验的讲师来说,咨询是必须的,以便理解标准并学习一些技能。小组合作是强制性的,以获得一些技能,及时完成过程。应该确立课程的目标。在第二阶段(开发阶段),课程设计以及生产计划应该与课程学习目标保持一致。然后,建立适当的评估,以确保学习者能够实现学习目标。在执行阶段作为第三阶段,沟通计划是为了确保课程能够达到目标受众。评估过程是为了获得反馈,以提高课程质量。企业家和新创企业这门课程的发展可能是一个很好的例子,它包含了其他讲师在创建在线MOOC课程时可以学习的经验教训。

The 21st century has witnessed extraordinary improvement on educational technique technologically known as E-learning. Google Classroom has officially been introduced to Malaysian schools in 2019 and all teachers have been given a training regarding this platform usage since then. Yet, very petite is known about STEM teachers' acceptance of this facility. The objective of this study is to propose an improved conceptual framework of modified UTAUT2 by introducing three new constructs namely, Self-Efficacy (SE), Trust (T) and Personal Innovativeness (PI) towards E-Learning acceptance. However, this study is mainly based on an in-depth recent literature review derived from Scopus database.
21世纪见证了教育技术的非凡进步,技术上被称为电子学习。谷歌课堂于2019年正式引入马来西亚学校,从那时起,所有教师都接受了有关该平台使用的培训。然而,很少有人知道STEM教师对这种设施的接受程度。本研究的目的是通过引入自我效能(SE)、信任(T)和个人创新(PI)三个新的构式,提出改进后的UTAUT2概念框架。然而,本研究主要是基于Scopus数据库的深入的近期文献综述。
