We describe how one department moved from skepticism to wide-spread embrace of coordinated Calculus I. Data played a crucial role in this process. Details of this journey, including successful strategies and missteps, may provide insight and perspective to other departments starting on, or immersed in, similar transformational adventures.

During the COVID-19 pandemic, many colleges switched to online or hybrid formats for both lecture and laboratory course delivery. While virtual experiments, that is, "dry lab" experiences, teach students chemical theory, it is essential for students in chemistry laboratories to participate in hands-on laboratory activities. These…

This paper provides details on a classroom experiment that focuses on returns to foreign assets given uncertain future exchange rates. Students are assigned the role of foreign analysts and decide how much to invest abroad given their expectations about future exchange rates. The experiment allows students to practice calculating the returns to…

Early social experiences, such as caregiver scaffolding, play a crucial but disputed role in the emergence of prosociality. A longitudinal experiment examined how explicit scaffolding--such as encouragement or praise--influences helping late in the first year, when helping emerges. Eighty-three infants (40 female, 6-9 months, 54% White, 17%…

The reflection and refraction of light are more familiar to students than the reflection and refraction of sound. Reflection and refraction that occur during the transmission of sound waves are common phenomena in everyday life but are often difficult to understand during actual learning. In this study, we developed a sound reflection and…

Physical experiments on real-world systems are proposed as a means to raise learning outcomes and Arduino microcontroller is highlighted as an appropriate tool to perform them. However, experimentation on a real system may encounter various barriers. Therefore, a learning environment was developed in order to perform Arduino experiments on digital…

Purpose: We discuss and preliminarily evaluate the SCA, a novel educational experiment that takes place in a Greek high school. Drawing on contemporary educational and political theory as well as the rich history of democratic ideas SCA has a twofold aim: to enable students to substantially participate in direct democratic decision-making…

This study aims to examine mathematics teachers' interpretations of students' thinking within the scope of teaching experiments as a professional development activity. The method used in this study is a teaching experiment. The participants are 3 elementary school mathematics teachers. The teaching experiment consists of 5 teaching episodes and…

In this work, a simple rocking pendulum, in a circular arc shape, is presented. The idea is to put a rigid arc on a clean flat surface of glass and leave it to oscillate under the effect of a little impulse. Then, the periodic time of this arc pendulum's motion is experimentally determined. The mathematical analysis of the arc's motion is derived…

Background: In exploratory learning, students first explore a new topic with an activity and then receive instruction. This inversion of the traditional tell-then-practice order typically benefits conceptual knowledge and transfer, but not always. Aims: The current work examines the impact of including contrasting cases in an exploration activity,…

Contribution: This article presents a teaching experiment platform for an undergraduate laboratory program designed to fulfill the needs of control engineering classroom experiment teaching. The teaching experiment platform is a cost-effective teaching tool that can be promoted on a large scale in colleges and universities. The teaching experiment…

The purpose of this study was to elicit preferences for the 'format' and 'content' of tobacco treatment among college student smokers, using an online discrete choice experiment (DCE) survey. A DCE survey, supplemented with a think-aloud method, was conducted among 54 college students who smoked combustible cigarettes and/or e-cigarettes.…

Via two reading experiments, this exploratory study examined the effects of over- and under-specified linguistic input on L2 online processing of Chinese referring expressions (REs). In each experiment, a group of advanced L2 Chinese speakers (all with Uyghurs as L1) and a control group of native Chinese speakers read 48 sets of 4 sentence pairs…

Currently, due to the radical transformations taking place in all spheres of education, the issue of improving the quality of education and the problems of training and educating specialists who meet all the needs of modern society is acute. The purpose of our research is to establish a theoretical substantiation of the use of new information…

The article describes a new version of a demonstration experiment for the Maxwell distribution. In the first part students analyse the applicability of the Gaussian distribution to the projection of the particle velocities in the suggested experiment. Further, students observe two-dimensional distribution of particles by the modulus of velocity in…
