A word association test was used to determine knowledge structures on biochemistry concepts of secondary school chemistry students, aged between 18-19 years. The basic biochemistry concepts related to the topic of Carbohydrates that take place in the International Baccalaureate Diploma Programme curriculum were determined as stimulus words:…

High school biology students are provided few classroom opportunities to learn natural history or to see themselves as scientists. This poses a risk to their gaining the basic knowledge needed to play a positive role in the biodiversity crisis. However, science-as-practice in the classroom introduces the opportunity to equip students with…

Teachers are eager for professional development on teaching evolution, especially if it includes direct ties to relevant curricula and detailed lesson plans. Howard Hughes Medical Institute's BioInteractive Online Professional Learning: Evolution course was developed to provide educators with free, in-depth, multimedia resources that highlight…

In 2018, in response to the proposed elimination of physics at a predominately Hispanic and socioeconomically disadvantaged (SED) high school, the Northern California/Nevada chapter of the AAPT investigated school demographics and their effect on physics offerings in public high schools in our region. As access was a key issue, the focus was on…

Purpose: The purpose of this mixed methods study was to examine the engagement of Hispanic Advanced Placement science learners in California's Central Valley as perceived by high school teachers. Methodology: The mixed method study surveyed 20 Advanced Placement science teachers from the region of interest. Likert surveys were used to determine:…

We examined the variation in Force and Motion Conceptual Evaluation (FMCE) preclass scores according to the type of physics class a student had in high school. This was done for students who had taken Physics 1 at a highly selective university. The majority of students had taken an Advanced Placement (AP) physics course, allowing us to examine in…

Science educators have begun to explore how students have opportunities to not only view and manipulate simulations, but also to analyze the complex sources of data they generate. While scholars have documented the characteristics and the effects of using simulations as a source of data in face-to-face, K-12 classrooms, how simulations can be…

As online education has exploded in the past decade, the number of physics and physics-related massive open online courses (or MOOCs, to use the industry lingo) has grown substantially as well. Several such courses aim at high school students, especially those involved in the AP Physics program. One of us (BK) was involved in creating two such…

This mixed method study was aimed at examining the influence of dual processing (Type 1 and Type 2 thinking) on the development of high school students' nature of science (NOS) views. Type 1 thinking is intuitive, experiential, and heuristic. Type 2 thinking is rational, analytical, and explicit. Three research questions were asked: (1) Do the…

Since 1987, the Statistical Research Center at the American Institute of Physics has regularly conducted a nationwide survey of high school physics teachers to take a closer look at physics in U.S. high schools. We contact all of the teachers who teach at least one physics course at a nationally representative sample of all U.S. high schools-both…

This article explains how issues regarding dual credit and Advanced Placement high school science courses could be mitigated via a flipped classroom instructional model. The need for advanced high school courses will be examined initially, followed by an analysis of advanced science courses and the reform they are experiencing. Finally, it will…

This "Science Note" looks at the way that the shapes of simple molecules can be explained in terms of the number of electron pairs in the valence shell of the central atom. This theory is formally known as valence shell electron pair repulsion (VSEPR) theory. The article explains the preferred shape of chlorine trifluoride (ClF3),…

Edwin Herbert Hall (1855-1938), discoverer of the Hall effect, was one of the first winners of the AAPT Oersted Medal for his contributions to the teaching of physics. While Hall's role in establishing laboratory work in high schools is widely acknowledged, his position as chair of the physics section of the Committee on College Entrance…

This "Science note" examines the bromination of phenol, a reaction that is commonly taught at A-level and IB (International Baccalaureate) as an example of electrophilic substitution. Phenol undergoes bromination with bromine or bromine water at room temperature. A white precipitate of 2,4,6-tribromophenol is rapidly formed. This…

The purpose of the current study is to explore the predictors of the Diploma Program scores in biology to resolve the dilemma regarding which international school curriculum is better to prepare students for the Diploma Program. A purposive sample of 135 high school students was drawn from a private international school in Turkey. Data was…
