This research study investigated conceptions about buoyancy held by 55 elementary preservice teachers enrolled in a science methods course who participated in an instructional intervention designed to increase their knowledge about buoyancy. Pre- and post-concept maps were analyzed using a paired sample t test and thematic analysis was used to…

This study investigated the stability and persistence of prospective elementary teachers' conceptual understanding of average speed. A questionnaire containing two questions about average speed was administered to the prospective teachers prior to their admission to an elementary science methods course (pretest) and at the end of the course…

Criteria are briefly proposed for final conclusions, research problems, and research hypotheses in quantitative research. Moreover, based on a proposed definition of applied and basic/general research, it is argued that (1) in applied quantitative research, while research problems are necessary, research hypotheses are unjustified, and that (2) in…

For misguided reasons, social scientists have long been reluctant to use gain scores for estimating causal effects. This article develops graphical models and graph-based arguments to show that gain score methods are a viable strategy for identifying causal treatment effects in observational studies. The proposed graphical models reveal that gain…

The COVID-19 pandemic kick-started a new paradigm shift in the way and manner teaching and learning takes place on the global scale due to the lockdown that succeeded in shutting down school activities. As a result, most institutions turned to technology supported e-learning as against the traditional face-to-face teaching and learning in order to…

The reliability of cognitive demand measures in controlled laboratory settings is well-documented; however, limited research has directly established their stability under real-life and high-stakes conditions, such as operating automated technology on actual highways. Partially automated vehicles have advanced to become an everyday mode of…

The purpose of this study was to investigate undergraduate students' conceptions of Earth scientists, using drawing as a tool, during introductory Earth science courses. We explored two research questions: 1) What student conceptions are evident in undergraduate students' drawings of Earth scientists? and 2) How do undergraduate students'…

The aim of the study was to evaluate the effects of a twelve-week pilates exercise program on some performance tests and body composition. The research was a quantitative study and experimental research model was used as a model. The study group consisted of 32 female volunteer students aged between 20-23 who were educated at Kirikkale University,…

The aim of this study is to explore the computational thinking (CT) processes of university students with the integration of CAS and ACODESA method within the context of problem-solving. The participants of the study are 22 university students. The embedded design was used in the study. The qualitative data consists of the written products of the…

Online learning provides students greater access to higher education opportunities when regular, on-campus options are not viable. However, for administrators and educators, online learning can be difficult to assess and ensure quality, which leads institutions to use quality assurance frameworks such as the Blackboard Exemplary Course Program…

Schools in economically marginalized areas often have a disproportionate number of low-performing or ineffective teachers and face challenges in recruiting and retaining highly effective teachers. The grow your own (GYO) model recruits and trains recent high school graduates and school employees who are interested in becoming classroom teachers.…

Explainable recommendation, which provides an explanation about why a quiz is recommended, helps to improve transparency, persuasiveness, and trustworthiness. However, little research examined the effectiveness of the explainable recommender, especially on academic performance. To survey its effectiveness, the authors evaluate the math academic…

The use of scientific calculators in teaching parabola functions has been shown to have significant effect in learner performance. This study examined the effectiveness of scientific calculators' usage in the teaching and learning of Grade 11 parabola functions to improve learner performance. Bandura's observational learning theory underpinned…

Learning analytics provides valuable data to inform the best decisions for each learner. This study, based on adaptive environment (AE) learning analytics dashboards, examines how instructor interventions affect student self-regulation abilities and academic performance. It identifies the self-regulation categories requiring the most support to…

Erduran and Dagher's (2014) account of the Family Resemblance Approach (FRA) to Nature of Science (NOS) is a relatively new framework that frames NOS in a holistic fashion, inclusive of cognitive-epistemic and social-institutional aspects. This approach has also been referred to as the "Reconceptualized Family Resemblance Approach to Nature…
