By Dawit Asrat Getahun
There is increasing recognition of the importance of learning contexts in science education. However, learning contexts are rarely articulated in terms of what they constitute and are often framed by educators and textbooks with limited inputs from students. Unless properly articulated, contexts become anything and everything, thereby losing their relevance for practical aspects of science teaching and learning. In this study, we examined secondary school students’ perceptions of learning contexts as they relate to their science learning and determined aspects of contextualising science education. We recruited 418 secondary school students (Grades 10 and 11) from eight schools in Bahir Dar, Ethiopia, to respond to a survey that has both closed and open-ended items. We used exploratory factor analysis to analyse the quantitative element of the survey and determine aspects of contextualising science teaching and learning. We also used open-coding and constant comparison to analyse students’ qualitative descriptions of learning contexts with the goal of determining students’ understanding of the concept as it relates to their science learning. Results from the factor analysis revealed four factors—agency and discourse, inquiry and processes, everyday life and community engagement and customising as aspects of contextualisation from students’ perspective. The results from the qualitative element reinforced those quantitative findings. Overall, results underscore the importance of contextualising as well as questioning the purpose of science education, especially, but not limited to, in low- and middle-income countries. The study has implications for learning design and fostering learner agency in science education. © 2024 Southern African Association for Research in Mathematics, Science and Technology Education (SAARMSTE).
Exploring Ethiopian Secondary School Science Teachers’ Conceptions about the Nature of Scientific Knowledge (NOSK)
By Tadele Demelash Teshale
This study examined secondary school science teachers’ conceptions of the nature of scientific knowledge (NOSK). The participants were convenient samples consisting of 48 (M = 38, F = 10) teachers from three secondary schools. An open-ended questionnaire was administered to collect data. Qualitative analysis involved comparing teachers’ responses to experts’ views on NOSK. Frequency counts and percentages were also used to describe the NOSK conceptions of participants. Based on the findings, the teachers held informed conceptions on two NOSK tenets and naïve conceptions on four of them. The participants generally held a naïve conception of NOSK, as evidenced by the fact that their conception aligned with informed conception only on two of the seven assessed NOSK aspects. Future research should use large samples, employing a quantitative approach to reveal secondary school teachers’ NOSK conceptions. © 2024 by the authors.
Institutional Setting and Its Influence on the Teaching of Mathematics: Implications to Implementing Reform Vision in Mathematics Education in Ethiopian Schools
By Dereje Taye Wondem
Existing initiatives in mathematics education demand establishing a continuous professional development program for teachers in Ethiopian schools. However, implementing such programs first requires an understanding of the school and district environment in which the participating teachers work, as mathematics instruction is in part a function of the environment. In many cases, school and district settings are dynamic, and it is difficult to incorporate unplanned and intervening factors into the change process. This case study attempts to investigate the influences of the school and district settings in promoting reform visions in mathematics education. This study applies the theory of communities of practice as a framework and qualitative coding of data to understand the dynamic school setting and its implications for the teaching practices of mathematics teachers. The findings reveal that the school setting does not adequately promote reform visions, but rather it maintains the practice that is supposed to be changed. The current situation includes an accountability system loosely connected to reform visions, the absence of reform-oriented school leaders and expertise to guide the teachers, and a lack of instructional materials that the teachers can refer to regarding the new reforms. This paper suggests a possible configuration of the school situation to promote an environment that fosters the teaching of mathematics toward reform objectives. © 2023 by the authors.
Representation of Image Formation—Observation in Optics in Ethiopian Textbooks: Student Learning Difficulties as an Analytical Tool
By Dawit Asrat Getahun
Studies have reported that students find geometric optics topics difficult partly because of representations in textbooks. In Ethiopia, textbooks are the main source of content in schools. Therefore, a study of how textbooks present certain topics can shed light on students’ learning difficulties. This study specifically examines how image formation–observation is presented in Ethiopian textbooks and how these representations might be the possible causes of students’ learning difficulties. Sixth-, eighth-, and tenth-grade physics textbook chapters containing topics related to image were analyzed. The analysis followed a directed approach to qualitative content analysis. The results show that textbooks sometimes contain explanations that explicitly clarify pictorials and are consistently integrated. However, the textbooks also contain implicit, missing, and incorrect verbal representations as well as incomplete, selective, and patterned pictorial representations that are presented inconsistently. Moreover, the textbooks rarely show alternative representations that complement the problematic representations, hence limiting their misinterpretations. Students may intuitively interpret implicit, selective, and patterned representations that may not conform to scientific concepts. Similarly, incorrect, missing, and incomplete representations could be seen as a direct source of students’ misconceptions. The results suggest that authors and teachers of optics textbooks should be aware of students’ learning difficulties because of representations and should emphasize alternative representations. © 2023 by the authors.
