Summary of SyMETRI meeting May 8th, 2023 by Qiaochu Xu

Presenter/Guest Speaker: Suresh Ghimire from the Department of Curriculum and Pedagogy, Faculty of Education, UBC
Date: May 8th, 2023
Host: Dr. Cynthia Nicol

In the SyMETRI meeting on May 8th, 2023,

Suresh began his presentation by stating that the aim of science education is not only to teach scientific content knowledge but also to develop scientific literacy and understanding of scientific inquiry skills. Educators have proposed various activity-based approaches to incorporate inquiry into science classes, but not all of them have been successful. Furthermore, the curriculum worldwide has long been criticized for being overstuffed and undernourished (AAAS, 1989, 1993), as it tends to provide a superficial overview of scientific concepts without delving deeper into understanding the scientific inquiry process. Suresh spoke about the science curriculum overly emphasizes scientific concepts while neglecting scientific process skills in many countries and including Nepal. Based on his 12 years of experience working with teachers, Suresh said it is evident that they are neither adequately trained nor supported in adopting inquiry-based teaching methods.

In responding to the inadequacy of inquiry-based learning and lack of hands-on activities in science classrooms, Suresh introduced the model-based inquiry (MBI) proposed by Windschitl et al. (2008), which centers on generating, testing, and revising scientific models. They argue that MBI can support science learning across all academic levels. Jonas Hallström and Konrad J. Schönborn (2019) also agree that models and modeling can be utilized to promote authentic STEM education and literacy. The potential of model-based inquiry seems particularly promising in Nepali schools with limited resources.

Suresh is interested to investigate the following questions:

  • What are the perceptions of Nepali science teachers on the use of hands-on activities facilitated by scientific modeling kits in science classrooms?
  • How can scientific modeling kits be effectively integrated into Nepali science classrooms to enhance student learning of big and small-scale scientific phenomena?

Suresh’s research aims to investigate the perceptions of Nepali science teachers who use Karkhana’s scientific modeling kits in their classrooms, specifically focusing on the potential of model-based inquiry facilitated by these kits. Karkhana is an education enterprise in Kathmandu working with schools to bring hands-on STEM experience for kids aged 0 to 18. Karkhana designs learning experiences that provide learners with opportunities to make things and shape their own worlds. Karkhana’s experiences allow children to practice and perfect the 21st-century skills of creativity, collaboration, critical thinking, and communication while using science, arts, and technology. The Hands-on science program designed by Karkhana is being implemented in more than 50 schools by around 180 teachers and reaching to 10,000+ students.

Additionally, his research will explore teachers’ views on the effectiveness of scientific modeling kits in enhancing students’ understanding of various scientific phenomena, ranging from atomic and planetary scales, which significantly differ in magnitude, such as size, distance, weight, temperature, motion, and other related variables. Suresh will return to Nepal for his data collection, we look forwards to hearing more about his study once he come back from Nepal.

Here are some slides from his presentation:

Summary of SyMETRI meeting April 11th, 2023 by Qiaochu Xu

Presenter/Guest Speaker: Dr. Marina Milner-Bolotin from the Department of Curriculum and Pedagogy, Faculty of Education, UBC
Date: April 11th, 2023
Host: Dr. Cynthia Nicol

In the SyMETRI meeting on April 11th, 2023,

Dr. Marina Milner-Bolotin began our meeting stating that learning science and math is often mistakenly thought of as simply memorizing formulas, equations, and procedures. However, in reality, it is about visualizing concepts by utilizing constructive help from the technology and tools available to us. Dr. Milner-Bolotin, Professor in EDCP, presented several innovative examples from her research to engage students in learning science, physics, and math, utilizing smartphones and other online interactive tools. For instance, using the slow-motion camera setting on a phone to record waves, she demonstrated how students can visualize the properties of wave interference. Another example shared focused on the image produced when a slab of chocolate is heated using a microwave with a turn-table that didn’t rotate. In this example students can observe the entire chocolate becoming a two-dimensional wave plate and recognize the need for a rotating plate. Dr. Milner-Bolotin’s spoke about how she hopes to encourage educators to think creatively about how to motivate students and promote hands-on, inquiry-based learning instead of solely completing the worksheets.

Technology tools mentioned and discussed in the meeting to support student inquiry where students can use apps on their cell phones included:

  • Desmos is an advanced online graphing calculator that offers various opportunities for digital math activities.
  • Phyphox which functions as a sensor in the phone for physical phone experiments. For example, students can produce a sound of a certain frequency and record it with a second phone. This enables students to not only hear the sound but also see how it looks, helping them visualize the difference between frequencies of 250 hertz and 500 hertz. This activity teaches students about the mathematical representation of the speed of the wave, which is equal to the frequency times the wavelength.
  • PhET Interactive Simulations, which creates and hosts explorable explanations for science studies. It can help to reinforce and clarify scientific concepts such as electricity, gravity, and energy transfer in a safe and engaging way.

Finally, the SyMETRI members discussed the challenges of adopting these technologies and tools in the classroom, including the need for educators to reconsider how they teach, and to be comfortable and confident with questions to which they may not have answers. Using technologies suggests requiring a willingness to make mistakes and the ability to model problem-solving with students. This practice also offers opportunities for interactive and hands-on learning and to develop of critical thinking skills.

Below are some of the slides from her presentation:

Presenter/Guest Speaker: Dr. Dawn Wiseman from the School of Education at Bishop’s University in Sherbrooke, Québec, Canada and Dr. Lisa Lunney Borden from St. Francis Xavier University in Antigonish, Nova Scotia
Date: October 17th, 2022
Host: Dr Cynthia Nicol

In the SyMETRI meeting on Oct 17, 2022,

During the meeting, Dr. Dawn Wiseman shared how Indigenous and Western ways of knowing, being, and doing circulate together in STEAM teaching and learning. She also introduced how she involved in the creating of locally relevant STEAM education, unlearning colonialism, and building her role and responsibility of educator in terms of connecting between Indigenous and non-Indigenous people and communities. She walked SyMETRI members through her lived experience by looking at how interactions and interrelationships between policy, practitioners, and practices.

SyMETRI members asked some critical questions of Lisa such as how might we understand the nature of Indigenous knowledge? What are the sources? And what are some ways we as teachers could bring that knowledge into our teaching?Lisa discussed how many Indigenous languages are verb-based rather than English which is more noun-based. She presented her research on decolonizing mathematics education through culturally based practices and experiences that are rooted in Indigenous languages and knowledge systems.

Presenter/Guest Speaker: Prof Marina Milner-Bolotin, Department of Curriculum and Pedagogy, Faculty of Education, UBC
Date: April 28th, 2022
Host: Dr Cynthia Nicol

Marina shared her recently published study on preservice physics teachers’ understanding of sound. In her presentation she discussed three questions:

  1. Why do we study teachers’ knowledge?
  2.  How do we study it?
  3. What do we do with the results?

A few slides from the presentation are below. The full presentation can be found here.

Abstract of the study

This study examines the knowledge for teaching of prospective secondary physics teachers as related to the subject of sound waves, specifically the topics of sound level and sound intensity. The data is comprised from future teachers’ responses to the task in which they had to compose a script for an imaginary dialogue between a teacher and a group of students and provide a commentary elaborating on their instructional choices. The topics selected for the task were chosen intentionally as they provide authentic and rich opportunities to bridge mathematics and science concepts while challenging future teachers to consider logarithmic measurement scale and its role in science. The task provided the beginning of the dialogue, that featured a student’s confusion related to the measurement of the sound level using a decibel scale. Future physics teachers were asked to extend this dialogue through describing envisioned instructional interactions that could have ensued. The instructional interchange related to the relationship between sound intensity and sound level, and particular teachers’ responses to the student ideas related to the meaning of a decibel sound level scale were categorized as featuring superficial or deep, conceptual or procedural knowledge for teaching. We describe each category using illustrative excerpts from the participants’ scripts. We conclude with highlighting the affordances of scriptwriting for teachers, teacher educators, and researchers.

13/01/2015 – First SyMETRI meeting of 2015 – Talking about science in YouTube Channels, Webcomics and books

For our first meeting of 2015 I thought it would be great to start off talking about some of the online science-related happenings. I briefly mentioned how science is becoming more popular in social media. People like Bill Nye and Neil Degrasse Tyson are quite often in the headlines defending or promoting science, but there are a lot more people out there doing the same thing, and they are gaining in popularity on social media sites such as Facebook, Twitter and YouTube (this is particularly important for reaching children and young adults). Click here to see a document with a list of great physics and math technology and web resources (including YouTube channels, educational websites and other teaching resources). I personally recommend the YouTube channels Veritasium, Smarter Every Day, Brainscoop and SciShow.

I also discussed a webcomic called xkcd, which contains humorous science/math/programming content. The warning label on the website reads:

Warning: this comic occasionally contains strong language (which may be unsuitable for children), unusual humor (which may be unsuitable for adults), and advanced mathematics (which may be unsuitable for liberal-arts majors).

Randall Munroe, the creator of the website, has written a book called What If – Serious Scientific Answers to Absurd Hypothetical Questions. In this book Randall answers absurd questions such as ‘Is it possible to build a jetpack using downward-firing machine guns?’ using science and math. The book is witty and quite interesting – I recommend it to anyone with a sense of humour and a love of science. I own a kindle/pdf version of the book and would not mind sharing it with anyone who is interested.

The last thing I talked about was a new children’s book coming out (it was in fact a book I backed on the crowdfunding site Kickstarter). The book is called Augie and the Green Knight and it is an adventure story about a scientifically precocious young girl in a world of fantasy. The book is meant for children, but it is written for people of all ages. Here is a link where the author talks more about the book. I also own the pdf for this book and can share it with whoever is interested.
