A summary of the most recent and important measurements in b physics is presented. The production of beauty particles in Z decays, b quark couplings, lifetimes, B-B0 oscillations, semileptonic b decays and studies of the number of charm quarks produced in b decays are reviewed. Extraction of the Cabibbo-Kobayashi-Maskawa (CKM) matrix elements |Vtd|, |Vcb|, |Vub| and implication for |Vts| are di...

We study student understanding of the direction of the magnetic force experienced by a charged particle moving through a homogeneous magnetic field in both the magnetic pole and field line representations of the magnetic field. In five studies, we administer a series of simple questions in either written or interview format. Our results indicate that although students begin at the same low leve...

Although there has been much research on how to help students learn physics, students still come away without a deep understanding of how physics has transformed the world around them and almost all leave with decreased expectations and a more negative attitude toward physics. We discuss an experiment to address this problem: a course weblog which discusses real-world applications of physics an...

Physics education researchers have compiled substantial evidence that student course outcomes can be improved if physics instructors incorporate research-based instructional strategies into their teaching. Some instructors find this evidence convincing and attempt to change their instruction. Some of these instructors are successful and some are not. This paper presents the results of a case st...

This section of AJP includes physics education research ~PER! articles. It continues the editorial process that begun with the green PER Supplementary Issues to AJP published in July of 1999–2001. The PER section ~PERS! is a response to the tension between the long-standing policy of AJP not to publish research articles and the growing interest within the AAPT community in PER. Articles in the ...
