Abstract

Penelitian kualitatif ini bertujuan untuk menentukan pendekatan penyelesaian masalah fisika kontekstual oleh pakar fisika. Masalah fisika kontekstual dalam kajian ini merupakan soal fisika yang menggambarkan pengalaman hidup kita sehari-hari. Subjek penelitian terdiri dari sepuluh pakar fisika dari Universitas Syiah Kuala. Metode pengumpulan data yang digunakan adalah tes tulis dan wawancara terstruktur. Hasil penelitian menunjukkan bahwa pakar fisika melakukan 20 pendekatan penyelesaian masalah sewaktu menyelesaikan masalah fisika kontekstual. Seterusnya penelitian ini juga memperoleh satu pendekatan umum yang sering dijalankan oleh semua pakar fisika apabila mereka diminta untuk menyelesaikan masalah fisika kontekstual. Dalam pendekatan ini mereka melakukan; (a) mengumpulkan informasi, (b) menentukan prinsip/konsep, (c) mengidentifikasi variabel, (d) membuat hubungan kuantitatif, (e) membina persamaan spesifik, (f) membuat subtitusi, (g) membuat perhitungan, (h) membuat keputusan dan (i) memeriksa kembali jawaban. Sumbangan penelitian ini adalah satu model pendekatan penyelesaian masalah  fisika kontekstual oleh pakar fisika yang boleh digunakan sebagai garis panduan untuk membantu pelajar dalam menyelesaikan masalah fisika kontekstual.This qualitative study aims to determine the contextual approach to solving physics problems by experts physics. Contextual physics problems in this study is a matter of physics that portray the experience of our daily lives. Research subjects consisted of ten experts from physics education, Syiah Kuala University. Data collection method used was a written test and structured interview. The results showed that physics experts do 20 approaches to solve the problem while solving the problem of contextual physics. So this study also found a general approach that is often executed by all physicists when they were asked to solve physics problems in context. In this approach, they do: (a) menghuraikan information, (b) determining the principles / concepts, (c) identified the variables, (d) make quantitative relationships, (e) develop specific equations, (f) make the substitution, (g) make calculation, (h) make decisions, and (i) to re-examine the answers. Contribution of this study is a model of a contextual approach to solving physics problems by experts in physics that be used as guidelines to assist students in solving physics problems contextual.

Abstract

This study aimed to determine the impact of the integration of engineering design process (asking, imagining, planning, creating and improving) in an electrical & magnetism module to improve problem-solving skills in physics among secondary school students in Aceh, Indonesia. The quasi-experimental study was carried out with 82 form three (age 15 years old) students of a secondary school in Aceh Besar, Indonesia. The first author had randomly chosen two classes as the experimental group and two other classes as the control group. Independent samples t-test analysis was conducted to determine the difference between the physics teaching and learning module which integrated the five steps of engineering design process and the existing commonly used science “Pudak” teaching and learning module. The results of the independent samples t-test analysis showed that the use of the physics teaching and learning module which integrated the five steps of engineering design process was more effective compared to the use of the existing “Pudak” module in increasing the students’ skills in solving physics problems. The findings of the study suggest that the science learning approach is appropriate to be applied in the teaching and learning of science to enhance science problem-solving skills among secondary school students. In addition, it can be used as a guide for teachers on how to implement the integration of the five steps of engineering design process in science teaching and learning practices.

Abstract

STEM teaching approach has attracted the attention of science educators as a panacea in addressing the deteriorating interest in STEM learning. However, the impact of STEM teaching approach on students’ achievement is scarcely discussed. Thus, this study aimed to explore the impact of integrating Science and Engineering teaching approach on the achievement of students. This meta-analysis was conducted systematically on articles published between January 2000 to January 2020 which were retrieved from five databases (EBSCOhost, Emerald, Scopus, Web of Science and ERIC).  Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) were applied to ensure a rigorous selection of the desired research articles. The data were then assessed using two online statistical effect size calculators. A total of 14 effect sizes were calculated. The overall mean effect size obtained was of high effect (es=2.61).  The Engineering Design Process (EDP)(es=3.26, high effect) was the most effective teaching approach in enhancing students’ understanding, as opposed to design-based learning.   An implication of the study is that EDP should be the basis for other teaching approaches in SE. Solving and creating tasks encourage application of concepts that then lead to enhancement of achievement.

Abstract

Increase of population, purchasing power, and development of technology give consequence to Waste of Electronic and Electrical Equipment (WEEE) or e-waste generation. Increasing rate of e-waste production and its hazardous content raise the concern regarding e-waste. This paper aims to describe the research development on e-waste in various countries and propose the perspective of future research. The study based on literature survey in open access journals using ‘e-waste’ as the keyword. Article selection was done by considering the reputability of the source and cited frequency. From the articles reviewed, China contributed to most of the researches. Some of most studied topic namely e-waste management, e-waste impact to human health and environment and current status of e-waste treatment in specific country. Brief explanation on each topic and insight on future research are also provided.

Abstract

The COVID-19 pandemic has affected education in Indonesia. The government has suggested alternatives to solve the learning problems during the pandemic. Offline and online classes were used to fulfil the various learning needs of students. This study investigated the effect of using augmented reality-assisted media in offline and online classes on student achievement amid the COVID-19 pandemic. This study used a quasi-experimental design by utilising augmented reality (AR) in each class for eight weeks. Validated test questions were used following the use of AR. According to the results of the independent t-test in the current study, student achievement from offline (n = 63, M = 74.71) and online (n = 64, M= 71.46) classes increased drastically with t = 1.994, p = 0.048. However, in terms of differences in achievement improvement between the two classes, students in offline classes had higher achievement compared to those in online classes. Thus, it can be concluded that student achievement in Physics has improved with the help of augmented reality-assisted media amidst the COVID-19 pandemic, particularly through offline learning mode. This study contributes to the development of AR for future education, particularly how to enhance student achievement in Physics. Future AR studies can be carried out in more classes from various regions or countries, considering that the 3D models in AR are useful to aid the learning of other subjects with abstract concepts.
