Derivatives and integrals are two important concepts of calculus which are precondition topics for most of mathematics courses and other courses in different fields of studies. A majority of students at the undergraduate level have to master derivatives and integrals if they want to be successful in their studies However, students encounter…

The study reported on in this paper is an interview study conducted with 20 7th and 8th grade students whose purpose was to understand the generalizations they could make about non-linear meanings of multiplication (NLMM) and non-linear growth (NLG) in the context of solving combinatorics problems. The paper identifies productive challenges for…

In this report, we will consider in-service elementary school teachers' noticing of the mathematical practice: justification. This study is part of a larger project evaluating the efficacy of a three year professional development built around attending to student thinking and promoting mathematical habits of justifying, generalizing and making…

Several models of language acquisition have emerged in recent years that rely on computational algorithms for simulation and evaluation. Computational models are formal and precise, and can thus provide mathematically well-motivated insights into the process of language acquisition. Such models are amenable to robust computational evaluation,…

Children often find it difficult to map verbs to specific referents within complex scenes, often believing that additional features are part of the referents. This study investigated whether 3-year-olds could use iconic gestures to map novel verbs to specific referents. One hundred and twenty children were taught verbs that could be interpreted as…

Inaccuracies, especially concerning the stimulus generalization findings, in textbook descriptions of the Little Albert study have been well documented since the 1970s. However, there has not been a systematic examination of introductory psychology textbooks since the 1980s to determine whether such inaccuracies still persist. This study filled…

The transition from preformal and propaedeutic generalization-actions to a symbolically explicit use of the concept of variable has been a matter of significant attention in mathematics education, for example in the context of generalization processes on a preformal level and regarding the specific nature of algebraic concepts. This contribution…

Searching for the real voices in regard to pedagogical challenges Iranian EFL teachers may struggle against seems to be an unexplored issue, which is the purpose of this qualitative grounded study. To achieve generalizable findings, based on the tenets of grounded theory, data were collected using an open-ended questionnaire with 187 Iranian EFL…

The purpose of this systematic review and meta-analysis was to synthesize the available research on the "Skills for Social and Academic Success" ("SASS") program, a school-based cognitive/behavioural intervention for adolescents with social anxiety disorder. A search of online databases, combined with reference list examination…

This case study presents the true story of Rodolfo--a former tailor and attorney from the provinces of Cuba--who moved to Havana to start a hospitality business. In 2016, the author (referred to as Adam throughout the case study), a business law professor from the United States, visited Havana to interview Rodolfo and learn about the factors for…

Purpose: This paper aims to explore the concept of sustainability imaginaries--unifying core assumptions on what sustainability entails held by stakeholders--set within a large suburban Canadian university. The study aims to expand the field of research into imaginaries by focusing on imaginaries within an institution as opposed to a societal or…

Instruction in academic core content provides students with moderate to severe disabilities a full educational opportunity that promotes current and future options in the community and can complement acquisition of daily living skills. However, high school teachers face many challenges in balancing instructional priorities given the mission to…

Classroom observations are increasingly common in education policies as a means to assess the quality of teachers and/or education programs for purposes of making high-stakes decisions. This article considers one policy, the Head Start Designation Renewal System (DRS), which involves classroom observations to assess the quality of Head Start…

The recorded text test (RTT) is commonly used to test dialect intelligibility, often to inform language development decisions. More than 25 papers using the RTT method were published on www.sil.org/silesr from January 2009 to March 2013. As introduced by Casad [1974. "Dialect Intelligibility Testing." Summer Institute of Linguistics…

Measuring treatment fidelity is an essential step in research designed to increase the use of evidence-based practices. For parent-implemented communication interventions, measuring the implementation of the teaching and coaching provided to the parents is as critical as measuring the parents' delivery of the intervention to the child. Both levels…
