The Dirac delta function is a standard mathematical tool that appears repeatedly in the undergraduate physics curriculum in multiple topical areas including electrostatics, and quantum mechanics. While Dirac delta functions are often introduced in order to simplify a problem mathematically, students still struggle to manipulate and interpret them.…

The aim of this study was to investigate the effects of the gender composition of university physics laboratory groups on student self-efficacy and quiz performance. Students from a Chinese university was chosen and subdivided into two groups, which were assigned either same-sex or coed laboratory teams while executing identical laboratory…

Nigerian students have not been performing up to expectation in public chemistry examinations. One of the causes identified as being responsible for this is the teachers' use of inappropriate instructional strategies. This study was conducted to determine the effects of mastery learning instructional strategy on secondary school students'…

Chemical stoichiometry is a conceptual framework that encompasses other concepts such as the mole, writing of chemical equations in word and representative form, balancing of equations and the equilibrium concept. The underlying concepts enable students to understand relationships among entities of matter and required amounts for use when…

This manual provides guidance and documentation for users of the kindergarten (or base year) data of the Early Childhood Longitudinal Study, Kindergarten Class of 2010-11 (ECLS-K:2011). It begins with an overview of the ECLS-K:2011. Subsequent chapters provide details on the study data collection instruments and methods; the direct and indirect…

The aim of this study was to investigate the effect of concept cartoons embedded within context-based learning approach on 8th grade students' alternative conceptions of "chemical bonding". Within a nonequivalent pretest-posttest control group design, the study was conducted with 45 8th grade students. To gather data, Chemical Bonding…

This article reports the development and validation study of tests to assess achievements at three levels of knowledge structure, following the model proposed by Sugrue to measure problem-solving skills. The literature has reported this proposal as a model consistent with the theoretical constructs underlying problem-based learning (PBL)…

In this article we compare students' understanding of vector concepts in problems with no physical context, and with three mechanics contexts: force, velocity, and work. Based on our "Test of Understanding of Vectors," a multiple-choice test presented elsewhere, we designed two isomorphic shorter versions of 12 items each: a test with no…

In the present study, we describe the innovative use of the National Board of Medical Examiners (NBME) Comprehensive Basic Science Examination (CBSE) as a progress test during the preclerkship medical curriculum. The main aim of this study was to provide external validation of internally developed multiple-choice assessments in a new medical…

Increase in tuition fees means there will be renewed pressure on universities to provide "value for money" courses that provide extensive training in both subject-specific and generic skills. For graduates of chemistry this includes embedding the generic, practical, and laboratory-based skills associated with industrial research as an…

Science content knowledge is internationally regarded as a fundamentally important learning outcome for graduates of bachelor level science degrees: the Science Threshold Learning Outcomes (TLOs) recently adopted in Australia as a nationally agreed framework include "Science Knowledge" as TLO 2. Science knowledge is commonly assessed…

"Proceedings of International Conference on Education in Mathematics, Science and Technology" includes full papers presented at the International Conference on Education in Mathematics, Science and Technology (ICEMST) which took place on March 24-27, 2022 in Antalya, Turkey. The aim of the conference is to offer opportunities to share…

This paper shows the results of an experiment in which the effects of fibroblast growth factor (FGF), actinomycin D (Act D; an inhibitor of transcription), and cycloheximide (CHX; an inhibitor of translation) were studied on the expression of two genes: a gene called "Fnk" and the gene coding for glyceraldehyde-3-phosphate dehydrogenase (GAPDH).…

This paper highlights some of the challenges and milestones inherent in building partnerships between institutions of higher education and public-school systems from an interdisciplinary approach. It discusses lessons learned from a Mathematics Science Partnership (MSP)-Start Partnership that was funded by the National Science Foundation from 2008…

This report presents Advanced Placement (AP) and International Baccalaureate (IB) examination participation and performance results in Texas public schools for the 2018-19 school year. Data are provided by student characteristics, including race/ethnicity; gender; and economic, at-risk, dyslexia, English learner, foster care, homeless, immigrant,…
