The aim of this work is to characterize the process constructing mathematical knowledge by higher education students in a distance learning course. This was done as part an algebra course within engineering degrees Colombian university. study used Transformative Sequential Design mixed methods research. analysis also determined kinds attained and its relationship social cultural context. acquir...

Instrument fidelity in message testing research hinges upon how precisely messages operationalize treatment conditions. However, numerous studies have unmitigated threats to validity and reliability because no established procedures exist guide construction of treatments. Their typically occurs a black box, resulting suspect inferential conclusions about effects. Because mixed methods approach ...

Background Mixed methods research designs are becoming increasingly popular in nursing to explore complex clinical issues and generate knowledge useful improve the quality of practice clients’ health outcomes. Q methodology is one such design that combines strengths both qualitative quantitative approaches examine scientifically peoples’ subjectivity towards a subject area. Aim This paper aims ...

In this paper we describe the process of redesigning a mobile outdoor mixed reality game. We introduce the design and concept of the first prototype and present the guidelines resulting from the first evaluation phase. The final section describes the redesign of the game based on these guidelines and patterns for game design.

In this paper, two-step sequential spin-dip and spin-spin coating, as well as one-step spin coating, methods are used to fabricate methylammonium lead mixed-halide perovskites to study the effect of process parameters, including the choice of the solvent, annealing temperature, spin velocity, and dipping time on the characteristics of the perovskite film. Our results show that using a mixture o...

biodegradation of phenanthrene (phe) was studied in aqueous culture to demonstrate the potential of the mixed culture in degrading high concentration of phe. the experiments were conducted to monitor biodegradation of phenanthrene for duration of 6 days. biodegradation of phe was successfully achieved in low and middle concentration by the isolated mixed culture. a full factorial central compos...

Little is known about how to systematically integrate complex qualitative studies within the context of randomized controlled trials. A two-phase sequential explanatory mixed methods study was conducted in Canada to understand how women decide to disclose intimate partner violence in emergency department settings. Mixing a RCT (with a subanalysis of data) with a grounded theory approach require...
