... regarding how nuclear radiation arises, there are many naïve ideas regarding the time it takes for radioactive nuclei to decay. Although the point at which an individual nucleus decays is taken to be random, there is nevertheless a characteristic time necessary for half of a large number of nuclei...

... that charge was created by rubbing. To explain the fact that metal bars do not get charged when rubbed, about one quarter of students in each cohort stated that rubbing caused electrons to move within the conductor but not to move to the cloth. About half of the students in each cohort ascribed a metal rod...

... school hours per week, half of the which are devoted to science. The physics part is quite limited, but the content is extensive. In the first two years, students use their bodies as measuring devices, discuss the motion, name different types of motion of humans and animals, discusses human and animal...

... simulation, a step-change at 5 s is only applied to the inlet temperature, which suddenly increases from 20 to 40 C. (3) Finally, in the third simulation, rogue step-changes in both inlet temperature and inlet mass flow rate are applied at 5 s. Specifically, the mass flow rate is half its original value...

... education. In physics, in particular, women students continue to be significantly underrepresented in doctoral programs compared with men students. Although half of the U.S. population are women (United States Census Bureau, 2019), only 19% of all physics students are women ( Mulvey et al., 2019...

... intervention with the camera obscura. The drawings that evolved from the consensus of each group's discussion showed that more than half of the participants advanced in their ideas toward the desired level of knowledge in relation to the phenomena studied, namely image formation. The researchers argue...

... to the same individuals twice. The split-half method splits one test into two similar or parallel sub-parts. The score on one half of the test should be similar to the score on the other half of the test, indicating consistency. Item covariance methods are similar to the split-half method, except the test...

..., and even the production in the first two years will account for more than half of the estimated ultimate recovery [EUR, see Fig. 1.1(a) ]. At the same time, the compositions of wellhead products from different gas wells may vary significantly, and even the wellhead product from the same well may change...

.... Fifty high school teachers were asked to evaluate given justifications to statements from elementary number theory. Teachers are not aware of students' preference for verbal justifications, while about half of the teachers rejected correct verbal justifications. They claimed that these justifications...

... to textbook definitions), and a process definition (referencing the process of energy transfer). Half of the ten students were categorized as using the caloric definition, two as operational, and three as process definitions. The authors then cross-referenced these definitions with descriptions of heat...

... al., 2020 ). For example, a short ecological belonging/mindset intervention by Binning et al., which only requires half of a single recitation class period at the beginning of the semester, eliminated the gender gap in calculus-based introductory physics performance ( Binning et al...

... to the underlying physics concepts. The most common strategy students used to draw the best-fit line was to split the data in half, so that half of the points were above the line and half of the points were below the line. This strategy was followed by the strategy to draw a line down the middle of the data points...

... are also recorded in the research. A survey conducted in Serbia ( Bogdanovic, 2019 ) shows that even pre-service physics teachers do not agree on whether students should use smartphones in the classroom, with half of them believing that their use should be banned in schools. Teachers who express different...

... to texts as the keywords relevant to reading or writing were found as listed comprehensive vocabulary, book sharing and science articles. For the next 5 years, biological contents were more addressed, e.g., genetic engineering, genetic information and life science. During the first half of the 2010s...

...) developed an “animated” version of the Force Concept Inventory, in which short and simple computer animation replaced the static diagrams of each question in the original version of the test. During a series of interviews, students were initially shown a random mix of questions, half of which were...

... and the band width ( Akhade and Kitchin, 2012 ). Interestingly, in TMOs containing early 3d TM ions like V³⁺ with less than half-filled d-orbitals, the frontier orbitals involved namely d_xy, d_yz, and d_zx are not directed toward the oxygen p...

... teaching physics without a subject- and teaching-specific preparation ranges between about one third in the UK ( Loveys, 2011 ) up to half of the classes in lower-academic track schools in one state of Germany ( Klemm, 2021 ) and about two-thirds in the U.S. ( Meltzer and Otero, 2014 ; and White and Tyler...
