Chemical kinetics is an important topic that is reinforced across the undergraduate chemistry curriculum, but previous research indicates students tend to have difficulty developing a sophisticated understanding of reaction rate. In this qualitative case study, we characterized how two students conceptualized reaction rate in the context of…

This paper shows the results of the epistemological and didactical analysis of the sense of variation of functions. Specifically, on the conceptions of growth and decay in a function that underlie the demonstrations of the theorem that links the sign of "f" with the sense of variation of "f". The epistemological approach…

While the 'action' portion of a Participatory Action Research (PAR) project is a crucial component of the process, action tends to be challenging to define, achieve, and measure. The current paper both defines and describes action within the context of a particular PAR collaboration and explores the process and challenges of navigating and…

This study aims at exploring L2 researchers' perspectives on research ethics in Iran. A total of ten teacher researchers were selected among a larger group of researchers based on the criteria of academic degree and familiarity with research principles. They were interviewed about different aspects of research ethics. Their responses were…

Recently Prof. Howard Gardner, an outstanding psychologist in the worldwide accepted the interview from Dr. Weiwen Zhang, and talked about a wide range of MI theory and relevant fields, which mainly involved in its core ideas, current situation and future development, and also involved its application in some current hot issues, which gave us…

In this paper, we take a semiotic/dialogic approach to investigate how a group of UK 12-13-year-old students work with hierarchical defining and classifying quadrilaterals. Through qualitatively analysing students' decision-making processes, we found that the students' decision-making processes are interpreted as transforming their…

In rapidly changing employment markets, career guidance has a vital role to play in supporting people in navigating transitions between education and employment across the lifespan. In this article, the issue of quality and quality assurance in career guidance is explored. Although there is no clear agreed international understanding of what…

'Emotional reactivity' (ER) is an important construct in the analysis of individual temperamental differences, and has accounted for significant variance in studies with respect to its definition. Between 1920 and 2015, the meaning of ER has varied from physiology of emotional reactions, to stress, depression, and as a sub-type of empathy. This…

Connecting the thermodynamic definition of entropy, dS = dQ/T (Clausius's equation), with the statistical definition, S = k[subscript B] ln [omega] (Boltzmann's equation), has been a persistent challenge in chemical education at the undergraduate level. Not meeting this challenge results in students taking away the meaning of entropy in a vague…

To directly investigate the reciprocal causal relationship of the conceptual and affective meaning of words, two priming experiments were conducted with the lexical decision task. In Experiment 1, the influence of semantic relatedness on the affective priming effect was explored by manipulating the semantic associative strength between the prime…

Active learning has gained growing political, instructional, and research interest. However, the definitions of active learning are wide. The learning outcomes related to it have been mostly positive but the measurement methods are not without problems. This review provides an overview of active learning, especially in the context of engineering…

This article aims to analyze the concepts and tendencies identified in research conducted on digital citizenship in the last ten years. To satisfy this objective, search parameters were established for articles in specialized databases. Within the results, the prevailing categories were concepts, abilities, empowerment, instruments, programs and…

The present paper takes its point of departure in risk being a relevant content for science education, and that there are many different approaches to how to incorporate it. By reviewing the academic literature on the use and definitions of risk from fields such as engineering, linguistics and philosophy, we identified key elements of the risk…

Children's intuitive understanding of numbers begins early in life, and their numbers-related knowledge influences instructors' teaching practices. The number zero is more difficult to teach and learn than other numbers. The purpose of this study was to investigate how preschool teachers perceive the number zero and design their teaching practices…

The authors develop the concept of teaching vocabulary for application (TVA) as a component of comprehensive vocabulary instruction. TVA is instruction that focuses on students' skillful application of small sets of words within academic tasks, such as text analysis and writing. The authors discuss how this instruction, with its extended focus on…
