Helping teachers in rural primary schools in Tanzania use ability grouping to improve learning, assess performance, and support struggling learners

Define the problem that your solution seeks to solve. [300-500 words recommended]

Effective assessment plays a pivotal role in fostering student success by enabling educators to identify learning gaps and customize instruction to meet individual needs. Research underscores the critical importance of ongoing, or formative, assessment in driving student achievement (Black & William, 1998). By providing educators with valuable insights into student progress and understanding, assessment serves as a cornerstone for informed instructional decision-making (Popham, 2008). 

In Tanzania, however, two factors limit the use of formative assessment. The first is class size - a formidable barrier to this essential practice. Particularly in rural primary school classrooms, large class sizes - sometimes 150 students or more - severely compromise meaningful assessments (Mushi & Mpango, 2020). As a result, teachers often resort to informal data or limited assessments, which fail to capture the nuanced learning needs of individual students (Sawe & Mushi, 2021). This situation perpetuates a cycle of educational disadvantage, with struggling students slipping through the cracks unnoticed (Mtebe & Raisamo, 2020).

The second factor limiting the use of formative assessment is teachers' attitudes: as in many parts of the world, teachers in Tanzania often believe their role is to dispense knowledge rather than to help students learn. Thus, when these teachers deliver a lesson to 100+ students, they can feel they have "done their duty" without assessing if every child has learned. In short, they don't believe they need to assess every child. It is simply not their role. 

Yet when teachers fail to continuously assess their learners, gaps in knowledge among students widen. Without timely intervention, students who fall behind remain undetected until summative assessments - e.g., end-of-year exams - reveal the extent of their academic struggles, often at a point where remediation efforts are too late or less effective (Makori et al., 2021). This pattern is reflected in national exam results, where a significant proportion of students fail to meet proficiency standards (Ministry of Education, 2021).

STS's work in Tanzanian schools has shown that flexible ability grouping can be a promising alternative. This approach allows teachers conduct regular formative assessments of their students' individual needs, then create temporary groups where those needs can be addressed. By understanding the strengths and weaknesses of each student through formative assessment, educators can deliver targeted instruction and support tailored to the diverse needs of their students (Kikafunda & Ssewamala, 2019). This approach has the potential to enhance learning outcomes for all students, particularly those who are struggling academically.

Describe your solution and how it works in simple terms. [300-500 words recommended]

Flexible ability grouping is a strategy that makes it possible for teachers, to collect real-time performance information. The flexible ability grouping procedure pioneered by STS in Tanzania consists of three basic steps:

• Group instruction. The teacher presents a lesson starting with whole class instruction, then organizing students into groups to continue learning from one another, then having the students complete an assessment in their groups which they score, then pass to a a group leader to tally, and finally, the group leader submits the results to the teacher.
• Analysis. Following the lesson, the teacher calculates the percentage of students meeting a minimum threshold (e.g., 3 out of 4 responses correct). If 70% or more of the students meet the threshold, the teacher plans the next lesson as she normally would. If less than 70% of students meet the threshold, the teacher plans to split the students into two groups: remedial and enrichment. If less than 30% meet the threshold, the teacher plans a remedial lesson for the whole class.
• Subsequent grouping decisions. In subsequent lessons, the teacher organizes students into the appropriate groups based on their assessment scores.

To date, what research/studies has your organization conducted or commissioned that have helped demonstrate the effectiveness of your solution? [300-500 words recommended]

To date, STS has conducted two waves of research on teachers’ use of flexible ability grouping. In the first wave (see link), STS trained 18 teachers from 6 primary schools in the use of this strategy, then conducted research on fidelity of implementation and participants’ perspectives to measure uptake and responses. In this wave, STS found that 94% of teachers had adopted ability grouping. One-third of these teachers followed the procedure as intended; however, the remaining teachers were still struggling with calculating assessment results and making appropriate regrouping decisions. In the second wave, STS introduced ability grouping to teachers in 2 new schools, where it reinforced its training design concerning the calculation of results and provided tools to help teachers track individual students' results. Of 6 teachers tracked in the second wave, fidelity was 100%: all had adopted the use of ability grouping. Most reported using it several times each week, and checks of the tools revealed that most were tracking student-level results and making correct follow-up grouping decisions.

What has the data collected from the research/studies revealed about your solution and how did it inform your work moving forward? [300-500 words recommended]

Following our first wave of research, we concluded that flexible ability grouping represented a viable strategy for teachers of large classes to differentiate instruction and conduct formative assessments. Following our second wave of research, we found that the ability grouping tracking tool not only helped teachers systematically track student-level results and grouping decisions, but it also helped STS monitor teacher uptake across cases. The second wave of research also reinforced the need for additional support to teachers in group learning and assessment activities and, most importantly for this proposal, a closer look at how teachers could productively respond to the needs of struggling students. These two aspects - curriculum support for learning and assessment activities and strategies for helping struggling students - are the focus of our ability grouping work moving forward.

Describe your organization's need to strengthen the evidence base of your solution. [300-500 words recommended]

Based on the successes described in previous sections of this proposal, the Arusha District Education Office has indicated its desire to scale the ability grouping approach to all the schools in the district.  For this reason, we believe that now is the right time to engage in the LEAP project: before scaling to Arusha’s 114 primary schools, the ability grouping process would be optimized if (1) the training and tools provided to date are reinforced with additional teaching and assessment aids, including support for remedial instruction, and (2) empirical evidence of the effectiveness of this model, including the additional aids and tools, could be generated to guide the scaling of the model to Arusha’s schools. Hopefully, this empirical evidence base will also interest the government and funders in expanding the model to other districts in Tanzania.

How will your organization put these outputs into action? [300-500 words recommended]

STS is currently raising funds to implement WCM activities during the 2025 school year in Tanzania (Jan-Dec). STS will use the results of this LEAP collaboration to seek additional funding for the proposed study and to advocate for scaling approaches at the district level based on findings from this research. 

Describe your desired long-term outcomes of the 12-week LEAP Project sprint for both your organization and solution. [300-500 words recommended]

Long-term outcomes include: (1) improved package for sharing the flexible ability grouping approach, by strengthening training and support for teachers, the inclusion of additional grouping & assessment aids and remedial strategies for teachers to use, (2) a stronger research base from which to advocate for specific strategies focusing on helping struggling learners, and (3) improved opportunities for scaling and expanded funding.
