Research has suggested that teaching and learning in molecular and cellular biology (MCB) is difficult. We used a new lens to understand undergraduate reasoning about molecular mechanisms: the knowledge-integration approach to conceptual change. Knowledge integration is the dynamic process by which learners acquire new ideas, develop connections…

The purpose of this study was to analyze organic chemistry students' annotations of reaction coordinate diagrams to better understand how they sought connections between reactions and reaction coordinate diagrams. Thirty-six students enrolled in Organic Chemistry II participated in semistructured, think-aloud interviews that asked students to…

Studies based on response processes of individuals can provide information that supports the assessment and increases the validity of the items in the scale or tests. The purpose of this study is to present the extent to which the student response processes are effective in identifying and developing the characteristics of the items in an…

[This paper is part of the Focused Collection on Astronomy Education Research.] As part of a larger project studying undergraduate students' understanding of cosmology, we explored students' ideas about the curvature of the Universe. We investigated preinstruction ideas held by introductory astronomy (ASTRO 101) students at three participating…

The aim is to reveal the views of the sixth grade Matter and Heat Unit on the technique of the students who work with the station technique. Qualitative method was used. The study group of the study was 25 students in the sixth grade who attended Ataturk Secondary School in the Cinar district, they were in the second year of the 2016-2017 academic…

This study aims to investigate the applicability of context- and problem-based learning (C-PBL) into teaching thermodynamics and to examine its influence on the students' achievements in chemistry, retention of knowledge, students' attitudes, motivation and interest towards chemistry. The embedded mixed method design was utilized with a group of…

The complexity of learning science rests in the fact that it not only possesses a unique lexicon and discourse but also that it ultimately entails a way of knowing. This article involves a case study that examines the academic engagement and perceptions of a group (N = 30) of high school students regarding their science literacy practices. These…

Paul Leslie Gardner pioneered the study of student difficulties with everyday words presented in the science context (Gardner 1971); several similarly designed studies (e.g. Cassels and Johnstone 1985; Tao in "Research in Science Education," 24, 322-330, 1994; Farell and Ventura in "Language and Education," 12(4), 243-254,…

Topic specific pedagogical content knowledge (TSPCK) is the basis by which knowledge of subject matter of a particular topic is conveyed to students. This includes students' prior knowledge, curricular saliency, what makes a topic easy or difficult to teach, representations, and teaching strategies. The goal of this study is to assess the…

Project-Based Learning has been the leading strategy used by most of the top educational systems in the world. Authentic learning that addresses the 21st century skills is what PBL offers. However, little research has been done to explore its potential in improving the quality of education in the country and what framework to be used to be able to…

Most recently, there has been a noticeable rise in the push for use of technology in the classroom. The advancement in digital science has increased greatly the capacity to explore animations, models, and interesting apps. that should substantially enhance science cognition. At the same time, there is a great need to increase collaboration in the…

The purposes of this study were first to investigate the effects of the project-based learning (PBL) method and project exhibition event on the success of physics teacher candidates, and second, to reveal the experiment group students' views toward this learning method and project exhibition. The research model called explanatory mixed method, in…

With the advent of the Next Generation Science Standards in engineering (NGSS, 2013), teachers of multiple subject areas are being asked to do more than ever before--not only to teach engineering content in the K-12 classroom but also to engage students in authentic disciplinary reading and writing as part of content learning. These standards…

The challenge of science achievement gaps is one that scholars have struggled to solve. Teacher leadership holds great promise in closing those gaps. Therefore, the purpose of the research reported here was to explore the responsibilities and supports of formally designated science teacher leaders (STLs) in urban elementary schools that have been…

Science students find heat, temperature, enthalpy and energy in chemical reactions to be some of the most difficult subjects. It is crucial to define their conceptual understanding level in these subjects so that educators can build upon this knowledge and introduce new thermodynamics concepts. This paper reports conceptual understanding levels of…
