Hey fellow impactful ninja ?

You may have noticed that Impactful Ninja is all about providing helpful information to make a positive impact on the world and society. And that we love to link back to where we found all the information for each of our posts.

  • Most of these links are informational-based for you to check out their primary sources with one click.

  • But some of these links are so-called "affiliate links" to products that we recommend.

Why do we add these product links?

First and foremost, because we believe that they add value to you. For example, when we wrote a post about the environmental impact of long showers, we came across an EPA recommendation to use WaterSense showerheads. So we linked to where you can find them. Or, for many of our posts, we also link to our favorite books on that topic so that you can get a much more holistic overview than one single blog post could provide.

And when there is an affiliate program for these products, we sign up for it. For example, as Amazon Associates, we earn from qualifying purchases.

What do these affiliate links mean for you?
  1. First, and most importantly, we still only recommend products that we believe add value for you.

  2. When you buy something through one of our affiliate links, we may earn a small commission - but at no additional costs to you.

  3. And when you buy something through a link that is not an affiliate link, we won’t receive any commission but we’ll still be happy to have helped you.

What do these affiliate links mean for us?
  1. When we find products that we believe add value to you and the seller has an affiliate program, we sign up for it.

  2. When you buy something through one of our affiliate links, we may earn a small commission (at no extra costs to you).

  3. And at this point in time, all money is reinvested in sharing the most helpful content with you. This includes all operating costs for running this site and the content creation itself.

What does this mean for me personally?

You may have noticed by the way Impactful Ninja is operated that money is not the driving factor behind it. It is a passion project of mine and I love to share helpful information with you to make a positive impact on the world and society. However, it's a project in that I invest a lot of time and also quite some money.

Eventually, my dream is to one day turn this passion project into my full-time job and provide even more helpful information. But that's still a long time to go.

Stay impactful,

📈 One key stat: The Arapaho language database contains over 100,000 sentences of natural speech, making it one of the largest such resources for an Indigenous language and providing crucial material for language preservation.
💬 One key quote: “The Arapaho people in Wyoming and Colorado believe their language can still survive, and so do I.”

1️⃣ The big picture: A professor at the University of Colorado Boulder has created an extensive database to help preserve the endangered Arapaho language, which now has fewer than 100 speakers, all over age 70. This database contains more than 100,000 sentences of natural Arapaho speech, complete with transcriptions, translations, and detailed linguistic analysis. The resource is being transformed into teaching materials through a structured 44-stage learning sequence that breaks down the complex language into manageable parts. This approach is now being introduced at Wyoming Indian Elementary School, pioneering dual-language classrooms on the Wind River Reservation.

2️⃣ Why is this good news: The database provides an unprecedented foundation for creating effective language learning resources tailored to different age groups and proficiency levels. By analyzing word frequency and grammatical patterns, educators can now develop progressive curricula that systematically build language skills. The project combines traditional documentation with modern technology while respecting indigenous perspectives on language preservation. Unlike previous scattered efforts, this comprehensive approach enables continuous language development from elementary through high school. The methodical preservation work gives the Arapaho people a genuine chance to maintain their linguistic heritage despite the dwindling number of native speakers.

3️⃣ What’s next: Teachers at Wyoming Indian Elementary School will implement the 44-stage learning sequence in their dual-language classrooms. More curricular materials need development, and additional teachers require training to use the new resources effectively. The Arapaho community must actively choose to learn and speak their language for the revitalization efforts to succeed.
