Abstract
Studies indicate that the failure of science education to meet the needs of the
21st century is to some extent due to the inability to incorporate scientific reasoning and
higher order assessments in the school instruction. Though the outcomes of education seek
higher-order thinking abilities there is a lack of high ability assessments in low-income
nations. The purpose of this mixed methods research is to explore students’ way of reasoning
and develop and validate the Scientific Reasoning Progress Tool (SRPT) which measures
students’ reasoning abilities. The phenomenographic study was used to explore grade eight
students’ patterns of reasoning, and to validate an assessment tool the descriptive survey
method was used. The qualitative analysis of students’ interviews elicited three major themes
of student views towards different levels of scientific reasoning: naïve, mixed, and scientific
along with the underlying ways of reasoning. For the quantitative part of the study, 40 items
were developed, pilot tested, and administered for 242 grade eight students at six schools.
Rasch Analysis was used to develop and validate the items with the help of Winsteps. It was
found that the SRPT is offered as a valid and reliable instrument that is a construct-driven,
domain-specific, and a higher-order thinking assessment that can measure students’ reasoning
progress. However, it was found that the reasoning ability of grade 8 students’ is limited to
lower level reasoning and they faced difficulty in attaining higher-level reasoning like
iv
generating evidence and drawing conclusions. This study has produced a valid and reliable
assessment tool to measure students' scientific reasoning abilities and a theoretical model that
could be used to develop assessment tools. The framework and design of this research may be
adapted to develop additional instruments to investigate the learning progression of students’
scientific reasoning in middle and high school classes in Ethiopian and other low-income
countries.
