This paper presents a praxeological analysis, based on ATD (Anthropological Theory of the Didactic), of the topic of Fourier series, as this topic is introduced and used in mathematics and in electrical engineering, more precisely in signal theory. The analysis is based mainly on one widely used textbook in mathematics for engineers, and a…

We examined associations between the quality of kindergarten teachers' mathematics instruction and their students' achievement and motivation in mathematics. Using a sample of 20 kindergarten teachers and their 285 students, we rated 5 video-recorded mathematics lessons per teacher throughout the spring semester with the Mathematical Quality of…

The pursuit of multiple educational outcomes makes teaching a complex craft subject to potential conflicts and competing commitments. Using a data set in which teachers were randomly assigned to classes paired with videotaped lessons, we both document and unpack such a tradeoff. Upper-elementary teachers who excel at raising students' math test…

Self-regulated learning has a positive effect on academic outcomes; however, little is known about whether and how teachers at various education levels promote it in their classes. Video-based classroom observations were conducted to assess primary and secondary school mathematics teachers' direct and indirect promotion of self-regulated learning…

The present study reviewed the papers in the Scopus database relevant to flipped classrooms in all mathematics subject areas published up until 2018 from various dimensions. It was found that there has been a considerable number of studies on flipped classrooms in mathematics education in these years. The majority were conducted in university…

This research describes language use by four first-grade students during mathematics and Language Arts instruction in a one-way 50/50 Mandarin immersion classroom. The urban public school was situated in the heart of an African-American community in the Pacific Northwest region of the United States. Participants were video- and audio-recorded…

Mathematics' skills and knowledge lay the basis for engineering studies. However, the resources targeted to mathematics' teaching are in many cases very limited. During the past years in our university the reduction of mathematics' contact hours has been significant while at the same time the study groups have grown. However, the mathematical…

Existing research from Western countries has consistently shown that the learning environment is an important factor for academic motivation. Self-determination theory, which serves as a theoretical foundation of the present study, suggests that teachers' involvement is an important element of students' learning, regardless of the cultural…

For the thirty-sixth year, the Research and Theory Division of the Association for Educational Communications and Technology (AECT) is sponsoring the publication of these Proceedings. Papers published in this volume were presented at the annual AECT Convention in Anaheim, California. The Proceedings of AECT's Convention are published in two…
