The paper presents an analysis of engagement markers in the Lectures on Physics by eminent scientist and Nobel prizewinner R. P. Feynman, based on K. Hyland's model of interaction in academic discourse as stance and engagement. The Lectures were taught at the California Institute of Technology during 1961-63 and, having been turned into a…

As mobile technology becomes more frequently used in science learning, understanding the relationship between student outcomes and the technology's pedagogical features is drawing increasing attention. This study focuses on one pedagogical feature--"who led the use." We first categorized 15 specific uses of mobile technology into three…

This paper presents protests from academically successful students who privately conveyed to the researchers their feelings of personal discontent with schools. The criterion to select this "sample" was that these students, dissatisfied with school but having good marks, would reveal what others, academically less successful, could not…

The paper discusses how a teaching approach, "interdisciplinary design and invention pedagogy," affected primary school student teachers' learning outcomes through the craft design process in pre-service teacher education. This study applies developmental work research (Engeström in J Educ Work 14(1):133-156, 2001; Engeström in…

In this study, a sociocultural perspective was adopted to understand the interplay between identity and agency in a context of science education reform in China. The manifestation of agency and the interaction between identity and agency were examined with two beginning science teachers teaching with practical work in high school. As part of this…

We present results from our ongoing investigation of student understanding of periodic waves and interference phenomena at the introductory physics level. We have found that many students experience significant difficulties when they attempt to express a distance of interest in terms of the wavelength of a periodic wave. We argue that for these…

In 1968, Robert Brehme wrote a carefully crafted paper on "The Advantage of Teaching Relativity with Four-Vectors." In his abstract he points out that "the emphasis on relativistic mass is both undeserved and misleading." Our approach is to find the best way to teach introductory physics in a way that includes modern physics. We have found that by…

What can physics students learn about science from those scientists who got the answers wrong? Your students probably have encountered little science history. What they have encountered probably has portrayed scientists as "The People with the Right Answers." But those who got the wrong answers can teach students that in science, answers are often…

In educational research, it is well-known that collaborative work on core conceptual issues in physics leads to significant improvements in students' conceptual understanding. In this paper, we explore collaborative learning in action, adding to previous research in engineering education with a specific focus on the students' use of free body…

Much of the mathematical reasoning employed in the typical introductory physics course can be traced to Pythagorean roots planted over two thousand years ago. Besides obvious examples involving the Pythagorean theorem, I draw attention to standard physics problems and derivations which often unknowingly rely upon the Pythagoreans' work on…

"Proceedings of International Conference on Social and Education Sciences" includes full papers presented at the International Conference on Social and Education Sciences (IConSES), which took place on October 17-20, 2024, in Chicago, Illinois. The aim of the conference is to offer opportunities to share ideas, discuss theoretical and…

This paper reports on an analyis of data from a novel "Peer Instruction" application, named DALITE. The Peer Instruction paradigm is well suited to take advantage of peer-input in web-based learning environments. DALITE implements an asynchronous instantiation of peer instruction: after submitting their answer to a multiple-choice…

Asteroids are clumps of rock, the sizes of which range from less than a kilometer to a few hundred kilometers in diameter. They are generally found in the unusually large gap between Mars and Jupiter. There are probably more than 40,000 asteroids in this gap called the "asteroid belt." In this paper we describe our efforts in confirming…

The mathematics behind Inge Lehmann's discovery that the inner core of the Earth is solid is explained using data collected around the Earth on seismic waves and their travel time through the Earth.

Many years ago I saw a picture of a huge set of wheels that was used to remove tree stumps during the construction of the Erie Canal (1817-1825) and was intrigued by its use of leverage, mechanical advantage, and torque. Figure 1 is a scale model of the device based on my memory of the (lost) picture and published accounts.
