Geosciences remains one of the least diverse science disciplines. Recent efforts in the discipline have aimed to address leadership, organizational, and structural factors to increase engagement of diverse participants. As these efforts expand, it is important to recognize the interrelated roles of distinctive social identities in affecting…

A vacuum cleaner is used to isolate over twelve harmonics in a corrugated toy whistling tube. The toy tube is first taped along a horizontal surface. Then a vacuum cleaner with a hose diameter approximately the same as that for the toy tube is turned on. As the vacuum cleaner hose approaches one end of the corrugated tube, individual higher…

The purpose of this study was to examine the effectiveness of astronomy activities in science education with preschool children through semi-structured interviews. The interviews were conducted with the children before and after the implementation of the activities. Five activities about astronomy were conducted for five weeks in practice. A total…

The aim of this study is to determine the awareness of science teachers about socio-scientific issues, the methods and techniques used in the teaching of socio-scientific issues, and the suggestions about effective teaching of socio-scientific issues. The sample of the study consisted of 75 science teachers (50 women, 25 men) who serve in various…

In "Science Education: A Societal Imperative," Paul H. Taylor references a society shaped by scientific concepts and technological forces, the need for citizens to make informed decisions about how science and technology are used in society, and how important it is for students to be scientifically literate in order to make informed…

Research is urgently needed to learn how to improve the emotional climate of science learning by ameliorating excesses of negative emotions, which may lead to students dropping out of school, teachers burning out, and health problems for both groups. This is especially true when teachers and students are situated in highly challenging environments…

Structure determination via NMR spectroscopy is a fundamental topic taught in many advanced level chemistry courses. Despite its importance as an analytical instrument, many students find the principle behind NMR-facilitated structure determination difficult to embrace. To this end, an artificial intelligence (AI) software package, namely,…

The abundance of questionable explanations is discussed and hypothetically related to common language, habitual teaching, ordinary popularization, rapid expression and audiences of varying levels. Two types of critical passivity in the face of a questionable text are recalled: 'expert anesthesia', which affects people who are very familiar with…

The purpose of this research was to investigate the efficacy of professional development in changing two middle school science teachers' questioning to include more questions that require deeper student responses. The professional development was based on ICAP theory which proposes a framework for identifying cognitive engagement based on what is…

Using voluntary and anonymous surveys, we have collected answers from more than 700 high school students about the types and sources of help they received with their science and engineering fair projects, the obstacles they encountered, the strategies they used to overcome obstacles, and the impact of science fairs on their interest in science and…

Learners need to develop multifaceted skills and knowledge in order to productively engage with today's increasingly uncertain world. To this aim, science educators strive to build students' science knowledge by engaging them in scientific practices, such as collaborative inquiry, which are social and collaborative in nature. However, learners…

In today's complex world, the acquisition of research skills is considered an important goal in education. Consequently, there is a growing body of literature that recognizes the value of well-designed learning environments for effectively supporting the development of this complex set of skills. However, a clear consensus on how these research…

This study aims to determine the effects of activities based on the Prediction-Observation-Explanation [POE] strategy on sixth grade students' understanding of the particulate nature of matter. The study was carried out with a sixth grade group consisting of 41 students from a middle school in an eastern city. Three activities were carried out…

This laboratory experiment employs an innovative approach to introduce undergraduates to liquid chromatography-tandem mass spectrometry (LC-MS/MS) by developing a method based on multiple reaction monitoring (MRM). During this qualitative investigation, students operated a triple quadrupole mass spectrometer in the MS scan and product ion scan…

In this paper, we propose a simple experimental apparatus that can measure the force variation over time to study the impulse-momentum theorem. In this proposal, a body attached to a rubber string falls freely from rest until it stretches and changes the linear momentum. During that process the force due to the tension on the rubber string is…
