One consequence of the widened participation in higher education (HE) is that the social demarcation line that once existed at the entrance to HE has moved inside the HE system. This study investigates how students experience social friction when demarcation lines are crossed and how such friction develops over time. This was achieved by repeated…

Using data from a participatory ethnography of an urban high school slated for closure, this article examines the impact of comprehensive transformation on the university-school partnership's goal to change from a culture of underachievement and negativity toward a culture of collaboration and excellence. We explore these question/s: How do…

In general, undergraduate experimental physics laboratories do not usually have experiments designed to address rolling friction and to measure the value of the rolling friction coefficient. This work explores an experiment, which has the potential to arouse students' curiosity about rolling friction by addressing a counterintuitive aspect of the…

Friction is one of the common forces that affect our everyday life and one of the oldest problems studied in physics. An interpretation of its nature is included in all general physics courses, in both high school and college. The desire and need to better understand it guided a long list of scientists who devoted themselves to the study of…

The current study investigates the differences in students' explanations of friction concepts after the use of the visuohaptic simulation with two different of sequenced approaches: enhanced visual first to enhanced visual and haptic feedback second (V [right arrow] V + H), and haptic enhanced first to enhanced visual and haptic feedback second (H…

The first phase of this multiphase study involves modeling of college students' thinking of friction at the microscopic level. Diagnostic interviews were conducted with 11 students with different levels of physics backgrounds. A phenomenographic approach of data analysis was used to generate categories of responses which subsequently were used to…

Video analysis is carried out for one-dimensional motion and collision experiments using Tracker. Physical variables, i.e. displacement, time, and velocity, can be deducted from the analysis and allows one to connect them to the equation of motion and energy conservation. Corresponding equations of motions are given without neglecting the effect…

This paper demonstrated a simple experiment for determining the coefficient of rolling friction of a hollow cylinder rolling on a curved track using a smartphone's sensors. We studied theoretically and experimentally the rolling motion of a hollow cylinder uncovered and covered with various materials (synthetic leather and sponge sheets). The…

The trajectory of a ball rolling across an inclined plane was recorded on video film to determine if it followed a parabolic path as others have suggested. The challenges in this case were (a) to determine the magnitude and direction of the friction force on the ball, (b) to determine the effect of the friction force on the trajectory and (c) to…

Perceptions of teachers and students about curriculum viability inhibitors are equally important yet may differ. Divergence can lead to destructive friction and adversely affect curriculum viability. Our team aimed to find the perceptions of teachers and students on inhibitors affecting the viability of an implemented medical curriculum, report…

We devised an activity to explore friction by testing some of the common theories on how ancient Egyptians moved the stones used to build the pyramids. The activity is suitable for a high school physics course or introductory college courses for both science majors and non-science majors. The students investigate dragging a 1-kg mass (representing…

Scientific concepts are the building blocks of scientific thought and science communication. Therefore, to achieve scientific literacy it is necessary to construct and define the concepts accurately. In this study, the concept of friction force, which is frequently encountered in science textbooks, is discussed. The explanations of the concept in…

Three years of data for 5,617 college online introductory statistics students were examined to determine if embedded course videos reduced incidences of external course tutoring. The frequency of external tutoring in course sections that used embedded videos was significantly reduced by 55% when compared to courses that did not use embedded course…

This article describes an experiment that can be done in the classroom in a simple way, with the support of a "homemade" device or as a laboratory practice with the support of PASCO equipment. Through a theory-practice sequence, kinematic and dynamic equations were checked with qualitative and quantitative analysis, emphasizing the…

The article scrutinized a friction stem in students, a false or a real of hope, struggle, and retentive in life when anxiety attacking the consciousness and bridging religious tradition and mental health status. Beyond reality to fantasy, within the inner perceptive, students construct artificial facts in the brain to stimulate action as a course…
