The ability to perform air-free chemistry and catalytic reactions on an NMR tube scale are valuable skills in chemistry and not often included in undergraduate chemistry curriculum. This laboratory experiment provides students experience in synthesizing the metal complex, Ni(dcpe)(CH[subscript 3]CN)[subscript 2](BF[subscript 4])[subscript 2] (dcpe…

Hypothesis generation is an important but difficult process for students. This study investigated the effects of providing students with support for hypothesis generation, with regard to the testability and complexity of the generated hypotheses, the quality of the subsequent inquiry learning processes and knowledge acquisition. Fifty-two…

Numeracy indicates number sense, measurement and geometry but is most often connected to number sense only. Since the domains of geometry and measurement are strongly connected to becoming skilful in science an intervention was carried out to improve children's science skills through measuring and geometry activities and enhance both their…

"N"-Formamides are important intermediates in the synthesis of many pharmacologically active compounds and are used as protecting groups for amines or as catalysts in different reactions. The current "N"-formylation experiment is designed as a part of an introductory organic chemistry course for undergraduate students. The…

The development of proficiency in the practices used by scientists and engineers is considered an important student outcome of laboratory instruction. We developed tasks to assess students' use and development of selected scientific and engineering practices in the general chemistry laboratory using an adapted evidence-centered design approach. In…

Laboratory education is a defining feature of chemistry degree courses, with one of the fundamental aims being acquiring competency in a range of chemistry-specific practical skills, yet there are still limited reports of direct assessment of these skills. Here, we present the development, implementation, and evaluation of a station-based…

The purpose of this study was to investigate the effect of inquiry-based experiments on pre-service science teachers' science process skills. The study group consisted of 60 pre-service teachers in total, enrolled in the undergraduate program of Science Teacher Education, Faculty of Education at a state university. The study which used randomized…

University lectures are mainly passive in nature, and there are few subjects in which students need to learn and function independently. Tutorial education and related activities at universities that specialize in medical and pharmaceutical training have been actively carried out, and lectures in conjunction with practical skills are gradually…

Object-based learning is an approach that aims to foster observational skills and sensory awareness. Paradoxical plant objects that do not lend themselves to all-too-easy explanations and interpretations can be used to practice the search for ecological explanations and the formation of evolutionary hypotheses. They can be the basis of…

Digital literacy is essential for scientific literacy in a digital world. Although the NGSS Practices include many activities that require digital literacy, most studies have examined digital literacy from a generic perspective rather than a curricular context. This study aimed to develop a self-report tool to measure elements of digital literacy…

One of the challenges that science teachers face is the lack of strategy/method to train students in data collection and developing analytical skills, which are pre-requisites to resolve socio-scientific problems and an important element in scientific literacy. In this activity, the SWOT analysis proposed by the Stanford Research Institute in the…

This study aims to reveal the effectiveness of the problem-based learning (PBL) model in teaching the concepts of heat, temperature and pressure, as well as the effect of the activities on the development of scientific process skills. For this purpose, the change in the academic achievement levels of the students constituting the sampling group…

The purpose of this study was to analyze visual attention during students' learning of Toulmin's argument pattern (TAP) and the effects of epistemic beliefs in science on the understanding of argument components. A total of 43 undergraduates were recruited through the Internet. Online questionnaires targeting beliefs about knowledge in science…

Students perceive chemistry as a complex subject resulting in low academic performance. Education systems shall support students in bridging the gap between traditional learning and online set-up using technology-based materials. The Electronic Strategic Intervention Material (E-SIM) is a new learning method to help improve the learner's…

The aim of this study is to examine the effect of the science module which was designed using the problem-based learning method on the basis of the Integrated Curriculum Model and applied in the blended learning environment on the scientific reasoning and scientific process skills of gifted students. The study was carried out with 9 gifted 5th…
