Spin(ing) into the classroom: Quantum spin activities for Year 6-10 physics

Quantum science is in the news daily and engages student interest and curiosity. A fundamental quantum science concept that underpins medical imaging, quantum computing and many future technologies is quantum spin. Quantum spin can explain many physical phenomena that are in the lower secondary school curriculum, such as magnetism and light, making its inclusion a great motivator for students. Here we present an activity sequence for teaching quantum spin in the classroom using spinning tops and gyroscopes to highlight the common properties of classical angular momentum and quantum spin. These toys can provide an easily understood window to the quantum world for lower secondary school students. Students who have engaged in these activities reported enjoying the content and appreciating its relevance.

On the effectiveness of the early introduction of modern physics in school curriculum: the case of the structure of atom versus wave-particle duality

The dual nature of matter and radiation and the concept of the structure of an atom share a number of key conceptual elements from quantum mechanics. Despite the similarities, we find that the concept of the structure of an atom is well understood by students, in contrast to the wave-particle duality. The study analyzes students' comprehension of these two concepts by conducting a semi-structured focus group interview and questionnaire. Through students' performance in the questionnaire and their descriptive responses, we find that the difficulties in their learning and understandings reflect the treatment of the respective topic in the curriculum. The introduction of the structure of an atom is early and repeated, whereas the dual nature of matter and radiation is introduced late and abruptly. Based on our findings, we propose reforms in the present curriculum that are necessary for an improved way of introducing the concept of modern physics, like wave particle duality, to Indian students.

Developing and implementing an Einsteinian science curriculum from Years 3 to 10 : Part A Concepts, rationale and learning outcomes

There has been a growing realisation that school science curricula do not adequately reflect the revolutionary changes in our scientific understanding of the 20th century. This discrepancy between current school education and our modern scientific understanding has led to calls for the modernisation of the science curriculum. Although there have been attempts to introduce topics of Einsteinian physics (i.e., quantum physics and relativity) to school education, often at the secondary level, we still lack a seamless curriculum in which modern science concepts are gradually introduced in primary and middle schools. Guided by the Model of Educational Reconstruction and following a mixed-methods research design, the Einstein-First project aims to address this gap. Einstein-First has developed and implemented an Einsteinian curriculum from Years 3 to 10 (students aged 7- 16) that resolves the disconnect between science in schools and the modern world. This paper presents the concepts, rationale, and learning outcomes of the curriculum implementation in six Australian schools with 315 students across Years 3 to 10. Our findings lay the foundation for informed curriculum development towards a school education that can enhance students' understanding and appreciation of the fundamental concepts of modern science and its impact on our society.

Developing and implementing an Einsteinian science curriculum from Years 3 to 10: Part B Teacher upskilling: response to training and teacher's classroom experience

Recent years have seen a growing interest in modernizing physics and science curricula around the world. While many science educators and curriculum developers design instructional resources to successfully introduce topics of Einsteinian physics to young learners, it is clear that successful curriculum development needs to rest on successful teacher professional development.Teachers with or without science backgrounds were trained in short professional learning workshops or completed micro-credential courses. The courses enabled teachers to gain knowledge and confidence to deliver the Einstein-First program. Detailed lesson plans and instructional videos for teachers define the lessons. Questionnaires were used to collect data, and teacher interviews were conducted following the various teacher training programs. The research results show that teachers effectively deliver the Einsteinian physics programs and that their subject matter and pedagogical content knowledge increased. In addition, teacher attitudes were favorable towards modernizing the physics curriculum. We conclude that it is feasible to upskill teachers from diverse backgrounds in Einsteinian physics and break the cycle that has inhibited the modernization of school curricula.

Can 8-Year-Olds understand concepts of Einsteinian physics?

This paper reports the first study on the ability of Year 3 students (ages 7 to 8) to conceptualize Einsteinian concepts. This paper reports that children aged 7-8 are not too young to learn key Einsteinian concepts, and the benefits of reinforcement indicate that longer programs are needed for ideas to be consolidated.

Long-term impact of a primary school intervention on aspects of Einsteinian physics

The physics that underpins modern technology is based on Einstein's theories of relativity and quantum mechanics. Most school students complete their compulsory science education without being taught any of these Einsteinian concepts. Only those who take a specialised physics course have the opportunity to learn modern physics. In 2011, the first study of a modern physics teaching intervention with an Australian upper primary (aged 10{11) class was conducted. The initial intervention was the first step of the Einstein-First collaboration towards challenging the current paradigm of Newtonian teaching in schools. It was found that modern physics concepts could be taught to these students. In 2020, 11 participants of the initial study (out of a total of 26) were contacted for a follow-up questionnaire and interview to investigate any long-term impact. The results of the follow-up indicate that the intervention maintained a positive impression on participants. The models and analogies used during the six-week intervention were highly memorable. The participants indicated that they found the intervention to be beneficial to their future learning. Even close to ten years after the intervention, the participants remembered several key concepts (such as curved space-time). The long-term follow-up indicates that Einsteinian physics can be taught at the upper primary level and be recalled several years later.

Gender response to Einsteinian physics interventions in School

There is growing interest in the introduction of Einsteinian concepts of space, time, light and gravity across the entire school curriculum. We have developed intervention programs and measured their effectiveness in terms of student attitudes to physics and ability to understand the concepts with classes from Years 6 to 10. In all cases we observe significant levels of conceptual understanding and improvement in student attitudes, although the magnitude of the improvement depends on age group and program duration. This paper reports an unexpected outcome in regard to gender effects. We have compared male and female outcomes. In most cases, independent of age group, academic stream and culture (including one intervention in Indonesia), we find that females enter our programmes with substantially lower attitude scores than males, while on completion their attitudes are comparable to the boys. This provides a strong case for widespread implementation of Einsteinian conceptual learning across the school curriculum. We discuss possible reasons for this effect.

Can a short intervention focused on gravitational waves and quantum physics improve students' understanding and attitude?

The decline in student interest in science and technology is a major concern in the western world. One approach to reversing this decline is to introduce modern physics concepts much earlier in the school curriculum. We have used the context of the recent discoveries of gravitational waves to test benefits of one-day interventions, in which students are introduced to the ongoing nature of scientific discovery, as well as the fundamental concepts of quantum physics and gravitation, which underpin these discoveries. Our innovative approach combines role-playing, model demonstrations, single photon interference and gravitational wave detection, plus simple experiments designed to emphasize the quantum interpretation of interference. We compare understanding and attitudes through pre and post testing on four age groups (school years 7, 8, 9 and 10), and compare results with those of longer interventions with Year 9. Results indicate that neither prior knowledge nor age are significant factors in student understanding of the core concepts of Einsteinian physics. However we find that the short interventions are insufficient to enable students to comprehend more derived concepts.

Public and Teacher Response to Einsteinian Physics in Schools

Einsteinian physics represents a distinct paradigm shift compared to Newtonian physics. There is worldwide interest in introducing Einsteinian physics concepts early in school curriculum and trials have demonstrated that this is feasible. However introducing Einsteinian concepts from an early age requires more than suitable curriculum and teaching resources - it also requires teacher training and public support. This paper describes a pilot study used in an attempt to gauge public and teacher support. This entailed giving teachers, who included the entire staff of a primary school, and self-selected family groups an in-depth understanding of proposed curriculum content through public outreach and professional development workshops. We assessed their attitudes through questionnaires. Comments and opinions from the public were also collected from online resources. Results show overwhelming support from both teachers and the public. We assessed attitudes of children as well as adults and obtained opinions regarding the appropriate age at which to begin to introduce Einsteinian concepts.

Evaluation of 14 to 15 Year Old Students' Understanding and Attitude towards Learning Einsteinian Physics

There is an increasing recognition regarding of the importance of introducing modern Einsteinian concepts early in science education. This study investigates the efficacy of an innovative educational programme "Einstein-First", which focuses on teaching Einsteinian physics at an earlier age than usual through the incorporation of appropriate hands-on activities. This paper presents an analysis of 14 to 15-year-old students' conceptualisation of Einsteinian physics and their attitudes towards science as a result of this programme. We have investigated the students' understanding of modern physics concept after a term of 20 lessons. We report on two such 20-lesson programmes, one delivered in 2013 and a second, improved programme delivered in 2014; each to 50-60 students across two classes designated by the participating high school as "academically talented" students. We found, as expected, that the students' possessed little prior knowledge of Einsteinian physics. the significant improvement in the students' knowledge, as tested before and after the course, showed that they could comprehend Einsteinian physics at the level it was given. The findings also showed that the short programme improved students' attitude towards physics.While the male students initially showed greater interest in physics compared to their female counterparts, the female students showed a significantly increased interest in physics after the programme. Also, students' memory retention of Einsteinian physics concepts was tested in two different years, one class was tested after one year of the programmes and the other was tested after three years of the programme. The results show that the Einstein-First programme had a lasting impact on the students involved in the study.

Teaching Einsteinian Physics at Schools: Part 3, Review of Research Outcomes

This paper reviews research results obtained from Einsteinian physics programs run by different instructors with Years 6, 9, 10 and 11 students using the models and analogies described in Parts 1 and 2. The research aimed to determine whether it is possible to teach Einsteinian physics and to measure the changes in students attitudes to physics engendered by introducing the modern concepts that underpin technology today. Results showed that students easily coped with the concepts of Einsteinian physics, and considered that they were not too young for the material presented. Importantly, in all groups, girls improved their attitude to physics considerably more than the boys, generally achieving near parity with the boys.

Teaching Einsteinian Physics at Schools: Part 2, Models and Analogies for Quantum Physics

The Einstein-First project approaches the teaching of Einsteinian physics through the use of physical models and analogies. This paper presents an approach to the teaching of quantum physics which begins by emphasising the particle-nature of light through the use of toy projectiles to represent photons. This allows key concepts including the spacing between photons, and photon momentum to be introduced. This in-turn allows an intuitive understanding of the uncertainty principle. We present optical interference in the context of individual photons, using actual videos showing the development of images one at a time This enables simple laser interference experiments to be interpreted through the statistical arrival of photons. The wave aspects of quantum phenomenon are interpreted in terms of the wavelike nature of the arrival probabilities.

Teaching Einsteinian Physics at Schools: Part 1, Models and Analogies for Relativity

The Einstein-First project aims to change the paradigm of school science teaching through the introduction of modern Einsteinian concepts of space and time, gravity and quanta at an early age. These concepts are rarely taught to school students despite their central importance to modern science and technology. The key to implementing the Einstein-First curriculum is the development of appropriate models and analogies. This paper is the first part of a three-paper series. It presents the conceptual foundation of our approach, based on simple physical models and analogies, followed by a detailed description of the models and analogies used to teach concepts of general and special relativity. Two accompanying papers address the teaching of quantum physics (Part 2) and research outcomes (Part 3).

Teaching the Einsteinian gravity paradigm

While Newtonian gravity is an adequate model for current geophysical exploration, Einsteinian gravity, based on the connection between free fall and warped time, has superseded Newtonian gravity as our best understanding of the universe. Einsteinian gravity is fundamental to GPS navigation and is a useful tool for geodesy. The Einstein-First Project is pioneering new curriculum material that seeks to teach students, from ages 11 upwards, the Einsteinian paradigm for gravity. By developing models, analogies and classroom activity based learning, we have found that students are fascinated and easily cope with concepts that adults, indoctrinated with Euclidean-Newtonian concepts, find difficult and confusing. This paper reviews the Einstein-First program, its methods and results of studies with students. We show that the majority of students demonstrate improved conceptual understanding and improved attitude to physics and that female students who enter the program with lower scores than male students, increase their performance to be level with the male students.

From adiabatic to non-adiabatic pumping in graphene nanoribbons

Non-equilibrium two-parameter pumping transport through graphene ribbons, attached to reservoirs is described. A tight-binding model is solved using Keldysh formalism, and the crossover between adiabatic and non-adiabatic regimes is studied. Pumped dc currents through armchair ribbons show properties common in two-dimensional systems. The width-dependent dc current in zigzag ribbons, reveals that edge states akin to those in two-dimensional topological insulators, do not contribute to pumped transport in the adiabatic regime. The interplay between propagating and evanescent modes is discussed.
