AbstractNovel considerations are presented on the physics, apparatus and accelerator designs for a future, luminous, energy frontier electron-hadron (eh) scattering experiment at the LHC in the thirties for which key physics topics and their relation to the hadron-hadron HL-LHC physics programme are discussed. Demands are derived set by these physics topics on the design of the LHeC detector, a corresponding update of which is described. Optimisations on the accelerator design, especially the interaction region (IR), are presented. Initial accelerator considerations indicate that a common IR is possible to be built which alternately could serve eh and hh collisions while other experiments would stay on hh in either condition. A forward-backward symmetrised option of the LHeC detector is sketched which would permit extending the LHeC physics programme to also include aspects of hadron-hadron physics. The vision of a joint eh and hh physics experiment is shown to open new prospects for solving fundamental problems of high energy heavy-ion physics including the partonic structure of nuclei and the emergence of hydrodynamics in quantum field theory while the genuine TeV scale DIS physics is of unprecedented rank.

Middle school physics experiment is a significant basic course with extensive content and strong practicability. This course has high requirements for students to master and understand the background and basic principles of various physical experiments, as well as the working principles and the use of various experimental devices. Based on the importance of physics experiment teaching and the limitations of the traditional experiment teaching mode, this paper first reviews the traditional mode in the context of the Internet and puts forward the new physics experiment teaching mode within "Internet Plus" in the new era, including theoretical guidance of constructing the experimental teaching mode, the innovation of teaching methods and examination methods, and the prospect of promoting the development of education industry. At the same time, this paper puts forward the network teaching platform system that can implement the new physics experiment teaching, including exercises, flipped classroom, and Massive Open Online Courses (MOOC), and discusses them separately, hoping to provide research reference for middle school physics teaching and research in the future.

The implementation of remote basic physics experiments during a pandemic has its own challenges. This experiment had problems in terms of planning, implementation, and reporting. The purpose of this study are to describe the implementation of synchronous distance learning of fundamental physics experiments using simple tools and to find out students' perceptions regarding the obstacles in the synchronous distance learning implementation of experiments. This research is a qualitative descriptive study. The instrument used is a questionnaire distributed using Google Form. The respondents in this study were 69 students who took the fundamental physics experiment course in the odd semester of the 2020/2021 academic year. Analysis of research data was carried out using descriptive analysis methods. The results of this study indicated that the application of Google Meetassisted experiments using simple tools and materials that were easily obtained by students could reduce the problem of completing tools and materials by students and the use of Google Meet allowed the mentoring process during the experiment by the lecturer. The most common obstacles encountered by students were obstacles in the implementation phase where sometimes the internet network did not support it while students needed to listen to the direction of the supporting lecturer, especially if the instructions in the manual were not well understood.

ABSTRACTThe COVID-19 pandemic requires teachers to think carefully and creatively in designing learning so that it remains interactive and appropriate to achieve the learning goals. Physics learning with using a flute and a smartphone described in this paper is the result of a thought process about how students can still conduct experiments from home using simple equipment to measure the speed of sound in the air and at the same time learn the concepts of loudness and pitch of sound. A total of 37 eighth grade students in 2020/2021 academic year and 23 students in 2018/2019 acadeymic year at a private junior high school in Bekasi were involved in a pre-experimental study with a one-group posttest only design. A set of 10-item multiple-choice diagnostic tests taken from the Mechanical Wave Conceptual Survey and summative tests in the form of structured questions were arranged to test students' conceptual understanding after receiving sound wave learning. The average of diagnostic test and summative test in the 2018/2019 and 2020/2021 academic years were 30, 48 and 60 respectively out of 100 with a summative test completion percentage of 35% in 2018/2019 and 70% in 2020/2021 . Keywords: physics experiment, sound waves, recorder, smartphoneABSTRAK Masa pandemi Covid-19 menuntut guru untuk terus berpikir secara hati-hati dan kreatif dalam merancang pembelajaran agar tetap interaktif dan tepat mencapai tujuan pembelajaran yang ditetapkan. Pembelajaran dengan menggunakan suling dan berbantuan gawai yang dipaparkan dalam tulisan ini merupakan hasil dari proses berpikir tentang bagaimana siswa tetap dapat melakukan eksperimen dari rumah memanfaatkan peralatan sederhana untuk mengukur kelajuan gelombang bunyi di udara dan sekaligus mempelajari konsep kekerasan bunyi (loudness) dan tinggi nada (pitch) bunyi. Siswa kelas delapan sebanyak 37 siswa tahun ajaran 2020/2021 dan 23 siswa tahun ajaran 2018/2019 pada salah satu sekolah menengah pertama swasta di Kota Bekasi dilibatkan dalam penelitian pre-experiment dengan desain one-group posttest only. Seperangkat tes diagnostik berbentuk pilihan ganda sebanyak 10 butir yang diambil dari Mechanical Wave Conceptual Survey dan tes sumatif berbentuk uraian disusun untuk menguji pemahaman konsep siswa setelah mendapatkan pembelajaran gelombang bunyi. Rata-rata tes diagnostik dan tes sumatif pada tahun ajaran 2018/2019 dan 2020/2021 berturut-turut sebesar 30, 48 dan 60 dari maksimum nilai 100 dengan persentase ketuntasan tes sumatif sebesar 35% di 2018/2019 dan 70% di 2020/2021.Kata kunci: eksperimen fisika, gelombang bunyi, suling, gawai
