Students entering into a quantitative analysis course often struggle with connecting theoretical aspects of concepts from lecture to hands-on applications in the laboratory setting. A one-semester quantitative analysis course was redesigned to integrate active learning with a project-based curriculum that incorporated structured review of…

The present study aims to demonstrate, by means of a meta-analysis, the effectiveness of Project-Based Learning in the context of academic performance and various study characteristics. For this purpose, the relevant literature was reviewed to identify studies using Project-Based Learning in the fields of physics, chemistry, biology, and science.…

This study investigates how the domain-specific language of molecular life science is mediated by the comparative contexts of chemistry and biology education. We study upper secondary chemistry and biology textbook sections on protein synthesis to reveal the "conceptual demography" of concepts central to the communication of this…

Making connections among multiple visual representations is key to students' learning. This article considers two learning processes involved in connection making: explicit sense making of connections and implicit perceptual induction of connections. Instructional interventions support these processes via different problem types: sense-making…

The ability of certain organometallic reagents to react via 1,2- or 1,4-addition to an a,ß-unsaturated ketone is a fundamental example of regioselectivity at the second-year undergraduate organic level. The following two experiments were designed to demonstrate this preference by exploiting carvone as an inexpensive chiral, nonracemic substrate.…

An undergraduate experiment for the organic laboratory is described that utilizes microwave heating to prepare 5- substituted 1H-tetrazole derivatives through a (3 + 2) cycloaddition between aryl nitriles and sodium azide. The reaction mixture is analyzed by thin layer chromatography. The products are purified through an acid-base extraction and…

The most important indicator of meaningful learning in science education is that the students learn and often encounter in their daily life in the description. To be able to implement this, students need to be a good science literate. This study was carried out in order to reveal to what extent the teacher candidates can explain the relationship…

The University of the South Pacific is owned by 12 nations in the South Pacific Ocean. The institution provides higher education through its 14 campuses, with at least 1 campus per member country. To be able to overcome the geographical divide and isolation, while ensuring high-quality learning and teaching, the university utilizes Internet,…

Federal legislation requires equitable access to education for all students at all levels, including in the postsecondary setting. While there have been a few studies in the chemistry education research literature base focused on how to support students with specific disabilities, this work seems to exist as a separate stream of research without…

The aim of the present research is to explain how the heuristics utilized by the students in a multiple choice examination on the general chemistry subject of "chemical bonding theories and molecular structures" caused biases on intuitive judgment and decision making processes, using the three characteristics of associative memory…

The purpose of this study was to enhance grade 11 students' conceptual understanding of fundamental acid-base models using Predict-Observe-Explain based animated movies (POE-AM). Twelve grade 11 students participated in the study. To collect data, the students' responses to the POE-AM tasks and interview protocols were used. The findings indicated…

This study aims to introduce the "Activity of Elements" that was designed by the researcher and to investigate the effect of this activity on student performance about elements and periodic table. The research was carried out with 15 students in the 8th grade. The activity consists of two stages: project preparation and competition. In…

This study aimed to explore the beliefs and attitudes of 36 science teachers (biology, physics and chemistry) in six high schools in Ankara towards the use of Interactive White Boards (IWB). Of these, three teachers from each school were chosen for interview and classroom observations according to their questionnaire results with purposeful…

Low cost, open-source analytical instrumentation has the potential to increase educational outcomes for students and enable large-scale citizen science projects. Many of these instruments rely on smartphones to collect the data, mainly because they can effectively leverage a dramatic price-to-performance ratio of the optical sensors. However,…

The study sought to investigate the role played by language in the academic performance of science students at a high school in the Free State province, South Africa who are taught through a language different from their mother tongue. The paper reports on the decisive mantle language plays in the comprehension and subsequent scholastic…
