The Role of STEAM Literacy on the Pedagogical Content Knowledge of Secondary School Mathematics Teachers in the Tigrai Region of Ethiopia

In the classrooms of the Tigray region in Ethiopia, mathematics teachers face a shifting landscape. They are being asked to move beyond teaching formulas in isolation and instead help students see how numbers connect to the wider world. To do this, many educators are turning to a framework known as STEAM, which stands for Science, Technology, Engineering, Arts, and Mathematics. This approach treats these five fields not as separate silos, but as a single, interconnected web where creativity and problem-solving meet. For a teacher to succeed here, they need more than just a deep understanding of math itself; they need a specialized kind of knowledge that allows them to take complex ideas and make them understandable for their students. Researchers call this Pedagogical Content Knowledge. It is the unique blend of knowing the subject matter and knowing the best ways to teach it, including how to spot where students get confused and how to use the right tools to fix those misunderstandings. The big question for educators in this region is whether a teacher's ability to navigate the STEAM world directly influences their ability to teach math effectively.

A team of researchers from Mekelle University set out to answer this question by looking closely at 300 secondary school mathematics teachers in Tigray. They wanted to see if a teacher's literacy in the five STEAM areas predicted their skill in teaching math. To do this, they asked the teachers to fill out detailed surveys about their own knowledge and confidence in science, technology, engineering, art, and math, as well as their teaching strategies. The study focused on a specific group of 300 teachers selected from a larger pool of over 1,200, ensuring a mix of men and women, different levels of education, and varying years of experience. The researchers then used statistical tools to see if there were patterns linking the teachers' STEAM knowledge to their teaching skills.

The results painted a clear picture of what matters most in the classroom. The study found a strong, positive link between a teacher's overall STEAM literacy and their ability to teach math well. In other words, teachers who felt more confident and knowledgeable across all five STEAM disciplines tended to have better teaching skills. However, not all parts of STEAM contributed equally. The strongest connection was found with mathematics literacy itself; teachers who had a deep grasp of math concepts were significantly better at explaining them to others. This was followed by engineering and technology literacy. Teachers who understood how to apply engineering principles to solve problems and how to use technology effectively also showed higher teaching competence. Interestingly, while science and art literacy were still important and linked to better teaching, they were not as strong a predictor of teaching skill as math, engineering, and technology were in this specific context. The data suggested that for these teachers, the ability to think like an engineer or use technology was just as crucial to their teaching success as their knowledge of art or general science.

The researchers also looked at how different personal factors might change a teacher's STEAM literacy. They discovered that gender did not make a difference; male and female teachers in the region showed nearly identical levels of STEAM knowledge and teaching ability. Education level, however, did matter. Teachers who had earned a master's degree reported significantly higher STEAM literacy than those who held only a bachelor's degree. This suggests that advanced study provides teachers with the integrated knowledge they need to handle complex, cross-disciplinary teaching. Experience played a more nuanced role. Teachers with between 11 and 20 years of experience demonstrated the highest levels of STEAM literacy. Those with less than a decade of experience and those with more than 20 years scored lower. This finding hints that while experience is valuable, it does not automatically guarantee mastery of new teaching frameworks. The teachers in the middle of their careers seemed to have found a sweet spot where they had enough time to practice integrating these new ideas but were still actively adapting to changes in the field.

The study concludes that to improve math education in Tigray, teacher training programs need to focus on building this integrated STEAM literacy. It is not enough to simply teach math content; teachers must be equipped to see how math connects to engineering, technology, and the arts. The data suggests that encouraging teachers to pursue advanced degrees and providing targeted support for those in the middle of their careers could be powerful ways to boost their professional skills. While the study relied on teachers' own reports of their abilities and was limited to one region, the patterns are strong enough to suggest that a teacher's ability to weave together different fields of knowledge is a key ingredient in making math understandable and engaging for students.
