Dimensional analysis is traditionally one of the first topics covered in a general chemistry course. Chemists use dimensional analysis as a tool to keep track of units and guide them through calculations. Although unit conversions are taught in a variety of subjects over several grade levels, many students have not mastered this topic by the time…

This paper gives an account of a teaching experiment on absolute value inequalities, whose aim was to identify characteristics of an approach that would realize the potential of the topic to develop theoretical thinking in students enrolled in prerequisite mathematics courses at a large, urban North American university. The potential is…

A review of prior research on the role of attendance policies in large lecture classes (including psychology) is presented. This research showed that although students often did not attend class, various policies were effective in getting students to the classroom. Moreover, some research showed that an attendance policy did not lower instructor…

A group of mathematicians and mathematics educators are collaborating in the fine-grained examination of selected "slices" of video recordings of lectures, drawing on Schoenfeld's Resources, Orientations and Goals framework of teaching-in-context. In the larger project, we are exploring ways in which this model can be extended to examine…

This article reports on students' experiences of lectures which included many opportunities for active engagement through cooperative learning activities. At the end of a 13-week semester-long unit, 113 students completed a questionnaire which contained five open-ended questions focusing on the extent to which the students thought that the lecture…

The experience of daydreaming is familiar to all, yet daydreaming and its correlates in an educational context have yet to be adequately explored. This study investigated academic and other potential correlates of task-unrelated images and thoughts (TUITs) during lectures. 463 undergraduate psychology students participated across three lecture…

These proceedings contain papers of the 3rd International Baltic Symposium on Science and Technology Education (BalticSTE2019) held in Šiauliai, Lithuania, June 17-19, 2019. This symposium was organized by the Scientific Methodical Center "Scientia Educologica" in cooperation with the Institute of Education, Šiauliai University. The…

In a recent study regarding online lecture videos, Evans (2014) shows that lecture videos are not superior to still slides. Using two Introduction to American Government courses, taught in a 4-week summer session, she shows that students in a non-video course had higher satisfaction with the course and instructor and performed better on exams than…

The current English-language research and educational program was driven by an initiative to create a more interactive, theme-based bilingual language education model for preschools in Chengdu, China. During a 2-week teacher education program centered at the Experimental Kindergarten of the Chinese Academy of Sciences in Chengdu, China, a team of…

The authors investigated whether the amount of instructional guidance affects science learning and self-efficacy. Sixty 9- and 10-year-old children were randomly assigned to one of the following three instructional conditions: (a) guided instruction consisting of examples and student-generated explanations, (b) direct instruction consisting of a…

Much arts education research is devoted to articulating the development of students' modes of thinking and acting, describing the development of various aptitudes in terms of the individual's experiences and accomplishments. This article presents a lecture by Olivia Gude, the recipient of the 2009 Lowenfeld Award. In this lecture, Gude focuses on…

This paper presents a new technique of delivery of classes--an instructional technique which will no doubt revolutionize the teaching and learning, whether for on-campus, blended or online modules. This is based on the simple task of instructionally incorporating text-to-speech software embedded in the lecture slides that will simulate exactly the…

Quickly accessing the contents of a video is challenging for users, particularly for unstructured video, which contains no intentional shot boundaries, no chapters, and no apparent edited format. We approach this problem in the domain of lecture videos though the use of machine learning, to gather semantic information about the videos; and through…

This study investigates how blending of different instructional approaches with technology affects students' engagement. A computer networks course was designed and implemented for the first eight weeks of the semester as a lecture-based blended learning environment and for the second eight weeks of the semester as a problem-based blended learning…

This paper presents a comprehensive overview of lexicogrammatical devices which highlight important or relevant points in lectures. Despite the established usefulness of discourse organizational cues for lecture comprehension and note-taking, very little is known about the marking of relevance in this genre. The current overview of…
