Molecular model kits have been used in chemistry classrooms for decades but have seen very little recent innovation. Using 3D printing, three sets of physical models were created for a first semester, introductory chemistry course. Students manipulated these interactive models during class activities as a supplement to existing teaching tools for…

Introductory undergraduate science courses are traditionally offered as distinct units without formalized student interaction between classes. To bridge science courses, the authors used three Honors Organic Chemistry projects paired with other science courses. The honors students delivered presentations to mainstream organic course students and…

This study explored how students visualise the states and classifications of matter with the use of scientific models. Misconceptions of students in using scientific models were also identified to formulate a teaching framework. To elicit data in the study, a Visual Conception Questionnaire was administered to thirty-four (34), firstyear, general…

The study investigated the effect of problem-based learning (PBL) on students' achievement in chemistry. Learners' low achievement in Science in South Africa has been a concern to government, stakeholders, school principals and parents over the years as a result of poor teaching techniques, students' attitudes, lack of teaching and learning…

This study aimed at determining the self-regulatory strategies and the chemistry self-efficacies of a total of one hundred and eighty-nine prospective science teachers in a state university in Turkey while studying the chemistry lesson according to the class level and gender factors. An additional goal was to examine the relationship level between…

This study seeks to develop a better understanding of the underrepresentation of women in science and engineering by analyzing the gender gaps (a) in the interest in pursuing a science degree and (b) on science achievement. We use national-level college admissions data to examine gender differences and to explore the association between these…

Both the Next Generation Science Standards (NGSS) and the new AP Chemistry curriculum focus on a deeper understanding of content, as well as application of concepts within science classes. A well accepted research-based method for improving student understanding and the ability to apply many of the abstract concepts presented in chemistry is…

Schools have been islands isolated from mobile technologies for a long time. In Finland, schools are investing in mobile technologies with the aim of providing a tablet for each student. This trend enables classes to adopt practices where students not only use ready-made learning materials but generate content as well. This paper aims to…

A laboratory exercise for the education of students about thermal runaway reactions based on the reaction between aluminum and hydrochloric acid as a model reaction is proposed. In the introductory part of the exercise, the induction period and subsequent thermal runaway behavior are evaluated via a simple observation of hydrogen gas evolution and…

The main purpose of the study was to find out the effect of ethnochemistry practices on secondary school students' attitude towards Chemistry. The design of the study was pre-test post-test control group quasiexperimental design. Two grade 11 intact classes were assigned into experimental and control groups randomly. The total sample size…

Many studies dedicated to the teaching and learning of organic chemistry courses have emphasized that high school students have shown significant difficulties in mastering the concepts of this discipline. Therefore, the aim of our study was to help students to overcome these difficulties by applying systemic synthesis questions, [SSynQs], as the…

The University of Pennsylvania's doctoral chemistry curriculum has included a required course in chemical information since 1995. Twenty years later, the course has evolved from a loosely associated series of workshops on information resources to a holistic examination of the chemical literature and its place in the general research process. The…

The perceptions of transferable and workplace skills development of year one and two chemistry undergraduate students at the University of Leicester were measured using two questionnaires. This group of students is taught by a variety of approaches including Problem and Context Based Learning (C/PBL). Over 60% of respondents agreed that all…

An action research study was conducted to determine how to increase student interest in learning science and pursuing a STEM career. The study began by exploring 10th-grade student and teacher perceptions of student interest in science in order to design an instructional strategy for stimulating student interest in learning and pursuing science.…

Organic chemistry is a traditionally difficult subject with high failure & withdrawal rates and many areas of conceptual difficulty for students. To promote student learning and success, four undergraduate organic chemistry and spectroscopy courses at the first to third year level (17-420 students) were "flipped" in 2013-2014. In the…
