Social network analysis (SNA) has been used in many educational studies in the past decade, but what these studies have in common is that the populations in question in most cases are defined and known to the researchers studying the networks. Snowball sampling is an SNA methodology most often used to study hidden populations, for example, groups…

Climate change science is complex and controversial in nature, yet seen by educators and policy makers as an important topic to be taught within secondary science education. This is becoming increasingly evident with the inclusion of climate change into the Next Generation Science Standards (NGSS) for Earth and Space Sciences as well as Life…

This study uses a mixed method sequential exploratory design to examine motivational and contextual influences on boys' and girls' engagement in math and science, paying particular attention to similarities and differences in the patterns by gender. First, interviews were conducted with 38 middle and high school students who varied in their level…

The present study aimed to determine the perceptions of science teachers on the implementation of the seven principles for good practice in education by Chickering and Gamson in their courses. Seven principles for good science education were used as a data collection tool in the survey. "The seven principles for good practice in science…

Changes in our global world have shifted the skill demands from acquisition of structured knowledge to mastery of skills, often referred to as twenty-first century competencies. Given these changes, a sequential explanatory mixed methods study was undertaken to (a) examine predominant instructional methods and technologies used by teacher…

Conferences are generally felt to facilitate knowledge exchange and interactions between delegates, and to support formative higher education and continued professional education. However, the motivations and needs of conference delegates are sparsely researched and subjective in nature. This paper presents a mixed method analysis of the needs and…

As women of color (WOC) enter the science, technology, engineering, and math (STEM) pipeline with aspirations to join the faculty ranks, it is important that the academy is prepared to address their unique needs to ensure they are supported as they engage in scientific and technological research, support students, and advance in their career.…

This study investigates the development of Topic-Specific Pedagogical Content Knowledge (TSPCK) of 14 novice uncertified graduate science teachers during a Professional Development Intervention (PDI) on teaching particulate nature of matter. TSPCK was defined in terms of five knowledge components: learner prior knowledge, curricular saliency,…

The purpose of this study is to examine the critical thinking skills of preservice science teachers in terms of various variables (gender, grade level, academic grade point average, participation in activities) and their opinions. In the research, sequential explanatory design, which is one of the mixed method research designs, was used. The study…

The Next Generation Science Standards (NGSS), are the biggest change to American science education since the National Science Education Standards (NSES) were published. While inquiry was central to the NSES, science assessment largely addressed factual knowledge acquisition. The NGSS represent a significant practical change for teachers as they…

The purpose of this study is to investigate the effects of teaching technologies and material development course taught through Moodle based online argumentation implementation on critical thinking disposition of third year science teacher candidates. The study was carried out with a total of 43 students consisting of an experimental group of 22…

Numerous empirical studies have provided evidence of the effectiveness of an explicit and reflective approach to the learning of issues associated with the nature of science (NOS) (c.f. Abd-El-Khalick and Lederman in "J Res Sci Teach" 37(10):1057-1095, 2000). This essay reports the results of a mixed-methods association study involving…

Background: This study is the second study of a design-based research, organised around four studies, that aims to improve student learning, teaching skills and teacher training concerning the design-based learning approach called Learning by Design (LBD). Purpose: LBD uses the context of design challenges to learn, among other things, science.…

This study explored the effects of arguing to learn in a socioscientific context on the fundamental and derived components of reading, writing, and science understanding as integral parts of science literacy. We adopted mixed-methods in which the 1-group pretest-posttest design with supplemental interviews and questionnaires. The pretest evaluated…

Background: STEM educational reform encourages a transition from instructor-centered passive learning environments to student-centered, active learning environments. Instructors adopting these changes incorporate research-validated teaching practices that improve student learning. Professional development that trains faculty to implement…
