Seventh-Grade Students’ Relational Conceptual Change and Science Achievement: Photosynthesis and Cellular Respiration Duo
This mixed-methods research study aimed to observe the changes in relational conceptual changes and achievement in photosynthesis and cellular respiration in 15 seventh-grade students using the variation theory of learning, a framework for contextual distinctions, and supports the Common Knowledge Construction Model (CKCM) for science education. The strategy used was prediction-observation-explanation, where students wrote and drew to express their macroscopic and sub-microscopic concepts, depicting any changes. Pre- and post-assessment tests were given to measure achievement in science. Through phenomenography analysis, five descriptive categories were generated for photosynthesis and nine for cellular respiration, revealing variations within and between students' ideas. Statistical tests showed significant improvements (p < .001) in photosynthesis and cellular respiration knowledge after implementing the CKCM learning sequence, with scores increasing from 37 to 77% and 33% to 72%, respectively. These findings suggest that inquiry-based learning based on relational conceptual change, guided by variation theory and an understanding of the nature of science, can lead to a deeper understanding of scientific explanations and improve overall science achievement.

Research in Science Education (RISE ) is highly regarded and widely recognised as a leading international journal for the promotion of scholarly science education research that is of interest to a wide readership.
RISE publishes scholarly work that promotes science education research in all contexts and at all levels of education. This intention is aligned with the goals of Australasian Science Education Research Association (ASERA), the association connected with the journal.
You should consider submitting your manscript to RISE if your research:
Examines contexts such as early childhood, primary, secondary, tertiary, workplace, and informal learning as they relate to science education; and
Advances our knowledge in science education research rather than reproducing what we already know.
RISE will consider scholarly works that explore areas such as STEM, health, environment, cognitive science, neuroscience, psychology and higher education where science education is forefronted.
The scholarly works of interest published within RISE reflect and speak to a diversity of opinions, approaches and contexts. Additionally, the journal’s editorial team welcomes a diversity of form in relation to science education-focused submissions. With this in mind, RISE seeks to publish empirical research papers.
Empircal contributions are:
Theoretically or conceptually grounded;
Relevant to science education theory and practice;
Highlight limitations of the study; and
Identify possible future research opportunities.
From time to time, we commission independent reviewers to undertake book reviews of recent monographs, edited collections and/or textbooks.
Before you submit your manuscript to RISE, please consider the following checklist. Your paper is:
No longer than 6000 words, including references.
Sufficiently proof read to ensure strong grammar, syntax, coherence and good readability;
Explicitly stating the significant and/or innovative contribution to the body of knowledge in your field in science education;
Internationalised in the sense that your work has relevance beyond your context to a broader audience; and
Making a contribution to the ongoing conversation by engaging substantively with prior research published in RISE.
While we encourage authors to submit papers to a maximum length of 6000 words, in rare cases where the authors make a persuasive case that a work makes a highly significant original contribution to knowledge in science education, the editors may choose to publish longer works.
