Research on Strategies for Enhancing Primary School Science Education in Africa Based on Innovative Teaching Resources: A Case Study of Tanzania ()
1. Introduction
In the context of balanced global educational development, science education, as a key factor in cultivating innovative talents and promoting social progress, has become increasingly prominent in importance [1]. The United Nations Educational, Scientific and Cultural Organization (UNESCO) clearly states in the Education 2030 Framework for Action that science education is an important way to promote global sustainable development and achieve educational equity and quality improvement [2]. However, due to historical, economic, and social constraints, the development of primary school science education in Africa lags relatively behind and faces numerous challenges [3].
As an important country in Africa, Tanzania’s educational situation to some extent reflects the overall picture of education in Africa. Although the Tanzanian government has made certain achievements in education popularization, problems such as a lack of teaching resources, a weak teaching force, and single-teaching methods still exist in the field of primary school science education [4]. These issues severely restrict the improvement of educational quality, resulting in generally low scientific literacy among students and making it difficult for them to meet the demand for innovative talents in future society.
With the rapid development of information technology and the continuous renewal of educational concepts, innovative teaching resources and new teaching models such as Project-Based Learning have been widely applied globally, providing new ideas and methods for solving problems in traditional science education. This study takes Tanzania as an example to deeply explore the application strategies of these new teaching models in primary school science education in Africa, aiming to provide theoretical support and practical guidance for improving the quality of primary school science education in Africa.
2. Significance of the Study
In the global context of educational development, primary school science education serves as a cornerstone for nurturing future generations of scientifically literate citizens. This study, focusing on the African continent with Tanzania as a case study, holds profound significance both theoretically and practically, aiming to bridge existing gaps and foster meaningful improvements in science education at the primary level.
2.1. Theoretical Significance
This study enriches the research achievements in the field of primary school science education, especially in the research on primary school science education in Africa. At present, research on primary school science education in Africa is relatively scarce, and most of it focuses on the description of the educational situation and problem analysis, lacking in-depth exploration of enhancement strategies [5]. By introducing innovative teaching resources and new teaching models such as Project-Based Learning, this study provides a new perspective and method for research on primary school science education in Africa, contributing to the in-depth development of research in this field [6].
Meanwhile, combining Tanzania’s specific national conditions and educational realities, this study constructs a framework of enhancement strategies suitable for primary school science education in Africa, offering a theoretical reference for other African countries in carrying out primary school science education reform and promoting the localization and diversification of primary school science education theories in Africa [7].
2.2. Practical Significance
The enhancement strategies of innovative teaching resources and Project-Based Learning proposed in this study have direct guiding significance for solving the practical problems faced by primary school science education in Tanzania. The introduction of innovative teaching resources can make up for the deficiencies of traditional teaching resources, enrich teaching content and forms, and improve students’ learning interest and participation. The promotion of Project-Based Learning can change traditional teaching methods, cultivate students’ innovative thinking and problem-solving abilities, and enhance their scientific literacy.
In addition, the research results can also provide practical references and lessons for other African countries in improving the quality of primary school science education. African countries face similar challenges and problems in educational development, and Tanzania’s successful experience can offer useful inspiration for other countries, promoting the overall improvement of primary school science education in Africa and driving the sustainable development of education in Africa.

4.1. Sampling and Respondent Composition
This study adopts a mixed-methods research design, combining quantitative and qualitative analysis. The 64 primary and secondary schools were selected using stratified random sampling, ensuring representation from urban, peri-urban, and rural areas across Tanzania. From these schools, a total of 157 respondents participated, comprising 72 students (aged 8 - 14, as primary school in Tanzania typically covers ages 7 - 13 but includes some overlap due to grade repetition and late entry), 30 parents, 40 teachers, and 15 educational administrators.
4.2. Data Collection Tools
The questionnaire survey covers aspects such as the current situation of science education, existing problems, key factors for improving scientific literacy, and the acceptability of innovative teaching resources. The questionnaire consisted of four main sections: 1) current situation of science education (e.g., availability of teaching resources, teaching methods), 2) student interest and engagement in science, 3) acceptability and demand for innovative teaching resources, and 4) demographic information. Response scales included Likert scales (1 - 5, from strongly disagree to strongly agree) and multiple-choice questions. Example items include “How interested are you in science classes?” and “Do you think digital textbooks would improve your learning experience?”. Pilot testing was conducted with 10 teachers and 15 students to ensure clarity and relevance, resulting in minor adjustments to wording. Internal consistency for multi-item scales was assessed using Cronbach’s alpha, with values above 0.7 indicating acceptable reliability.
Semi-structured interviews were conducted with 60 stakeholders, including 15 teachers, 15 parents, 15 students, and 15 educational administrators. Participants were selected using purposive sampling to ensure diverse perspectives. Interviews lasted approximately 30 - 45 minutes each and were conducted in Swahili or English, depending on the participant’s preference. The qualitative analysis procedure involved transcription, coding using NVivo software, and theme derivation through iterative reading and discussion among the research team. Coding steps included open coding to identify initial concepts, axial coding to establish relationships between concepts, and selective coding to refine themes.
4.3. Qualitative Analysis Procedure
Qualitative data from interviews were transcribed verbatim and analyzed using thematic analysis. Coding steps included familiarization with the data, generating initial codes, searching for themes, reviewing themes, defining and naming themes, and producing the final report. Two researchers independently coded a subset of transcripts to ensure inter-coder reliability, with discrepancies resolved through discussion and consensus.
5. Data Analysis and Results
The data collected through questionnaires and interviews has been meticulously analyzed to provide a comprehensive understanding of the current state of primary school science education in Tanzania, as well as the potential for innovative teaching resources and methods to enhance its quality.
5.1. Current Situation of Science Education
The results of the questionnaire survey and interviews jointly reveal the current situation of primary school science education in Tanzania. For each reported percentage, the denominator (total number of respondents in each group) is clearly stated. For example, “35.09% of all respondents (n = 157), including 42.5% of teachers (n = 40) and 28.6% of parents (n = 30), identified lack of teaching resources as the main problem.” Results are also disaggregated by respondent group where applicable to highlight differences in perceptions and needs (see Table 1). 35.09% of the respondents believe that the lack of teaching resources is the main problem currently facing science education. In the interviews, many teachers mentioned that due to the lack of basic teaching materials and experimental equipment, many scientific experiments cannot be carried out, and students can only learn scientific knowledge through theoretical study, lacking practical experience. For example, one teacher said, “We don’t even have a basic microscope, so biological experiments are simply impossible.” This shows that the lack of teaching resources severely restricts the quality and effect of science education.
At the same time, 47.37% of the respondents believe that the limited professional knowledge of teachers is a key factor restricting the quality of science education. In the interviews, teachers generally reflected that due to the lack of systematic training and further education opportunities, their scientific knowledge and teaching methods cannot keep pace with the development of science. One teacher mentioned, “Many of us teachers are non-science majors, and our understanding of scientific knowledge is not in-depth enough.” This limitation in professional knowledge makes it difficult for teachers to explain scientific concepts in an easy-to-understand way during the teaching process, affecting students’ learning effects.
In addition, 31.58% of the respondents believe that the low learning interest among students is another major problem currently facing science education. The questionnaire survey shows that students generally have low interest in science courses and think that science courses are boring and difficult to understand. In the interviews, students mentioned that they would prefer science courses to be combined with real-life situations and to stimulate their learning interest through hands-on experiments and Project-Based Learning. One student said, “Science class is really boring if it’s just listening to the teacher talk.” This shows that traditional teaching methods are difficult to stimulate students’ learning interest, and more vivid and interesting teaching methods need to be introduced.
