This is potentially the first study that addressed the Puerto Rican high school students' chemistry knowledge acquisition using traditional teaching and Physics Education Technology. The problem addressed by this quantitative comparative quasi-experimental study was that students' showed a disadvantage on chemistry knowledge acquisition over other…

Background: Video lectures which include the teachers' presence have become increasingly common. As teacher enthusiasm is a nonverbal cue in video lectures, more and more studies are focusing on this topic. However, little research has been carried out on the interactions between teacher enthusiasm and prior knowledge when learning from video…

Science dissemination or popularization of science refers to the act of facilitating the understanding of research and works of scientific and/or technological origin among the general public. Science dissemination is a relevant issue in the realm of public policy. Considering that in Brazil, the university is responsible for most of the…

In this study, we compared the effects of cooperative flipped learning (CFL) on science achievement and learning motivation with those of simple flipped learning (SFL) and traditional lecture (TL) using a mixed-methods design. Three classes containing a total of 65 first-year high school students in South Korea were randomly assigned to the CFL,…

Understanding chemistry requires the interplay of several modes of representations which can be observed in the translational skills of students. This paper investigated the extent of the translational skills of students exposed to conventional lecture method (CLM) and the integrated macro-micro-symbolic approach (IMMSA). Individual interviews…

This study applied an unconventional use of past examination papers by converting questions into hands-on experiments for students. Students in an experimental group were engaged in use of those experiments while the remainder attended conventional lectures with written practice. The results reflect that the experimental group positively improved…

The flipped classroom is a blended, constructivist learning environment that reverses where students gain and apply knowledge. Instructors from K-12 to the college level are interested in the prospect of flipping their classes, but are unsure how and with which students to implement this learning environment. There has been little discussion…

Lecturing is an important aspect of the culture of science education. Perhaps because of the negative associations constructivist educators make with lecturing, little research has been done concerning the generally invisible aspects of the (embodied, lived) "work" that is required. Traditional research on science lectures focuses on…

Here we present a multidisciplinary educational unit intended for general, advanced placement, or international baccalaureate-level high school science, focused on the three-dimensional structure of proteins and their connection to function and disease. The lessons are designed within the framework of the Next Generation Science Standards to make…

High school students have had some difficulties in understanding chemistry due to traditional ways of teaching this specific science. It is important to improve teaching methods that increase student motivation, not only to enhance their capacity for understanding, but also to generate a greater level of interest in the study of chemistry for…

Three emerging technologies were used in a large introductory chemistry class: a tablet PC, a lecture capture and replay software program, and an online homework program. At the end of the semester, student usage of the lecture replay and online homework systems was compared to course performance as measured by course grade and by a standardized…

While lecture demonstrations have been conducted in chemistry classrooms for hundreds of years, little research exists to document the frequency with which such demonstrations are employed or their effect on learners' motivation and performance. A mixed-methods research study was performed, using quantitative and qualitative survey data, along…

Many versions of the classic Ira Remsen experience involving copper and concentrated nitric acid have been used as lecture demonstrations. Remsen's original reminiscence from 150 years ago is included in the Supporting Information, and his biography can be found on the Internet. This article presents a new version that makes the demonstration more…

The aim of the International Society for Technology, Education, and Science (iHSES) conference is to offer opportunities to share ideas, discuss theoretical and practical issues, and connect with the leaders in the fields of "humanities," "education" and "social sciences." It is organized for: (1) faculty members in…

These proceedings contain papers of the 3rd International Baltic Symposium on Science and Technology Education (BalticSTE2019) held in Šiauliai, Lithuania, June 17-19, 2019. This symposium was organized by the Scientific Methodical Center "Scientia Educologica" in cooperation with the Institute of Education, Šiauliai University. The…
