Our experience has led us to believe that the process of teaching is as important as the content of instruction, and that if we are to increase the diversity of scientists, STEM instruction must undergo a transformation at a fundamental level. To address this need, we assume a sociocultural and constructivist framework. This means that we believe that learning is a dialectical process[1]; in which peer learners co-construct knowledge with instructors as facilitators or guides[2]; through which artifacts are created through the social interactions of a group; and co-constructed knowledge can emerge from within the community of learners.[3] Constructivist interactions depend on perceiving the individual as a unique and valued participant whose background and worldview bring needed knowledge and perspectives to both classroom and real world discussions.[4] In this context, learners become active participants in the learning process,[5] who gain confidence in negotiating academic topics through their activity[6] within a social process.[7] Learning is facilitated by instructors who function as knowledgeable others, rather than as ultimate authority figures in the learning process. Such instructors understand the individual positions and knowledge level of their students,[8] as a result of continuous dialogue with students,[9] embedded within a zone of proximal development[10] (see Figure 1 below). Knowledge produced in such classrooms is said to be socially and culturally constructed,[11] with individuals initiating personal additions and changes in their knowledge as a part of the appropriation process.[12]

We recognize that for pedagogical purposes, instruction and content need to be informed by both the local use of culture and language[13] and by local epistemologies and ontologies, as well as the content of traditional Western pedagogy.[14] Pedagogical style can be understood as taking place within Vygotsky’s Zone of Proximal Development (ZPD; see figure 1). Our UNM PI, Anne Calhoon, and her doctoral student, Elsie Moses-Hoeg, expanded the ZPD conceptually to include instances of specific behavior observed in classroom interactions of 5th graders who demonstrated group work in which new knowledge was created by discussions that pushed the boundaries of what participants knew independently.[15] Working to understand this phenomenon in undergraduate student learning groups will be central to our work in the proposed project.

In developing this curriculum website we explored several components of this model within classes taught by experienced faculty who were involved in curriculum development. This approach had two major effects: 1) students realized that their own knowledge and traditions had influenced the way they perceived the natural world and led to their interest in science, and 2) no particular perspective was privileged over any other. In many instances, Native American undergraduates ended up teaching students from other cultural traditions about how to perceive the natural world from the perspective of relatedness and connection (TEK).This turned out to be highly effective in drawing in students who found themselves alienated by the dualistic, reductionist concepts of positivistic Western science.[16] To quote two of our (non-Native American) students: A Biology major);"  said, "I think the class is enlightening in the sense that it’s making me realize that all of my education has been guiding me to the same angle, you know what I mean, so having me think a certain way. So having this class has made me realize that thinking about science from different angles is actually very scientific.” An Environmental Science major defined her perspective on this as, “It's made me realize I guess how other...ethnicities can really contribute to helping (solve) our environmental problems. We focus a lot on Indigenous people, and they have just their traditional ways of life (that) can really contribute to helping solve our those (sic) problems and making those connections sheds more light (on possible solutions).”

We conceptualize the content and learning structure of our work as illustrated in Figure 1 above, which shows how two mutually taught bodies of knowledge can be effectively included within courses in order to increase the flexibility of student learning. Specifically, the approach used in our project showed students that there are very important issues that traditional STEM content and instructional pedagogy do not teach, that all people in their future communities have valuable knowledge that must be heard and respected, and that science as enacted in life is a continuous learning experience informed by multiple voices.[17]

There remain areas within the U.S. in which languages other than English are the primary teaching and learning languages, and language preservation projects developed by many Tribes are strong components of teaching and learning in both informal (community-based activities) and formal communities (school-based activities). This means that students develop within a very different cultural milieu that influences their understanding of concepts even when they move into the English-language based university curriculum. Of those states within which such instructional and learning settings exist, Alaska is home to a variety of Alaskan Native communities who speak eleven major Indigenous languages with multiple related dialects. Some communities of Indigenous Alaskans remain so remote that instruction in the language of those communities is the first language used in all settings.[18] We can employ the model in Figure 2 to help us understand the place of differences in worldviews in development of concepts within a culture and how these function for instruction of students. Our approach, therefore, is especially useful for collaborators at UAA. In addition, collaborators at NAU and UNM, who are in regions with large populations of both Native Americans and Hispanics, also benefit from this approach.

Evaluating Student Learning and connecting the curriculum to students’ science identities have been shown to be linked to teacher style and type of content,[19] as well as to the sociocultural milieu of the classroom[20] and their community identities.[21]
