Insight Into

This study aims to investigate the mathematical proficiency promoted by mathematical modelling tasks that require students to get involved in the processes of developing mathematical models, instead of just using known or given models. The research methodology is grounded on design-based research, and the classroom design framework is supported by complexity science underpinnings. The research intervention consists of high-school students, from a grade 11 mathematics course, aiming to solve four different modelling tasks in four distinct moments. Data was collected during the intervention from students’ written mathematical work and audio and video recordings, and from recall interviews after the intervention. Data analysis was conducted based on a model of mathematical proficiency and assisted by interpretive diagrams created for this research purpose. This research study offers insight into mathematics teaching by portraying how mathematical modelling tasks can be integrated into mathematics classes to promote students’ mathematical proficiency. The study discusses observed expressions and behaviours in students’ development of mathematical proficiency and suggests a relationship between mathematical modelling processes and the promotion of mathematical proficiency. The study also reveals that students develop mathematical proficiency, even when they do not come to full resolutions of modelling tasks, which emphasizes the relevance of learning processes, and not only of the products of these processes.

The purpose of this design based research study was to better understand and build from students’ perceptual experiences of visual representations of the greenhouse effect. Twenty undergraduate students were interviewed as they engaged with an online visualization for the learning of the greenhouse effect. We found that, even though all students agreed that climate change is happening, a majority initially held a misconception about how it works. Upon engaging with the visualization, students made perceptual inferences and formulated causal rules that culminated in an improved description of how climate change works. This trajectory was supported with prompts from the interviewer to make predictions, observe specific interactions in the visualization and revise their causal inferences based on these observations. A case study is presented to illustrate a typical learning trajectory.

Educational researchers, leadership, and policymakers have had the privileged voices and place from which to theorize and address educational inequities. But for some exceptions, nondominant families have been relegated to participation in school-centric “parent involvement” activities. Drawing from a participatory design-based research study using standpoint and critical race theory, our findings suggest key convergences between the lived experiences and insights of nondominant parents and recent educational equity scholarship, while revealing untapped expertise, knowledge, and capacity for addressing inequity. We argue that holding a “place” for the complex understandings of nondominant families can open expansive possibilities for transforming educational systems toward racial equity.

And Diffusion

The process of technical change from the economist's viewpoint may be broken down into three phases: invention, innovation, and diffusion. Invention, or the increase in technological possibilities, is the discovery or perception of new configurations of technical processes or principles that alter the array of possible production functions. An innovation consists of using any given production function for the “first” time. Diffusion is basically imitative and involves the gradual replacement of old methods by the new. One example will suffice to illustrate these distinctions. The invention of the automatic bottle machine consisted of the conception, experimentation, and model-building activities of Michael J. Owens; the pioneering efforts of the entrepreneurs at Toledo, Ohio, to demonstrate that the new production function was both practical and economically feasible constituted the innovational phase; and the gradual replacement of hand-blown and semiautomatic machine methods by the new process in both American and foreign markets involved diffusion.

The purpose of this study was to investigate and explore the level of junior high student’s motivation during online learning in pandemic COVID-19. In this design-based research study, motivation level is examined by ARCS survey, interview and observation. The total of respondents were 180 students with different degree levels of study, gender and academic achievement. The analyzed data was measured by SPSS. From this research, the result shows that students of middle degree level have the highest motivation level during pandemic. A statistically significant difference in motivation level is also seen at the beginning of online learning and at the middle of online learning.
