Science education is believed to be a vital tool for individual and societal development at large. The persistent low levels of students' achievement in sciences at the various public examinations in Nigeria have continued to draw the attention of major stakeholders in education. This study examined academic achievement of Senior Secondary School…

Context-based approaches aim at increasing students' learning and motivation. However, students perceive its complexity often as overwhelming, causing frustration and disengagement. Thus, there is a need for innovative teaching methods to scaffold students in context-based education. Two perspectives are used to argue that Scrum methodology, a…

The authors investigated the effects of differing question-stem designs (detailed stem, simple stem, and no stem) on elementary students regarding the quality of the posed questions by students, as well as their science reports, science achievements, and critical thinking ability. A quasi-experimental design was adopted. One hundred fifth-grade…

In this study, evaluative case study was used to determine the realization level of the outcomes in the 10th chemistry curriculum. The 23 outcomes in the 10th grade chemistry curriculum were analyzed by two researchers. In order to determine the realization of the achievements based on practice, a chemistry teacher who attended the 10th grade…

Potential differences in achievement between female and male students have always been an interesting topic in educational research, as well as having policy and economic implications. This study provides an overview of the so-called "gender gap" in mathematics and science knowledge, based on an in-depth analysis of both extremes of…

Abstract In a technologically driven society, math and science students in the United States are falling further and further behind their international counterparts, resulting in an influx of STEM focused, reformed K-12 schools, including schools focused on project-based learning (PBL). This article reports a study of the effectiveness of PBL on…

Women's underrepresentation in mathematics-related careers continues to concern policymakers, economists, and educators. This study addressed the issue by examining data from two international databases, namely IEA's "Trends in International Mathematics and Science Study 2015," and the World Economic Forum's "Global Gender Gap…

We present results from the first randomized experiment of a remedial inquiry-based science education program for low-performing elementary students in a developing country. Among third-grade students in 48 low-income public elementary schools in Metropolitan Lima who score in the bottom 50% of their school baseline science distribution, half are…

This study investigated 8th-grade science students (13-14 years old) in advanced and traditional ability classrooms perceptions of their vocabulary knowledge, learning, and content achievement. This research acknowledges the critical role that developing vocabulary knowledge from reading plays in gaining a deeper content understanding as well as…

This study explored the effects of a middle school physical activity intervention for adolescent girls on the executive functioning involved in science learning. The girls, ages 11 to 14, were at risk for low self-esteem, sedentary lifestyle, and poor health outcomes. Executive function stems from interdependent cognitive control processes that…

Creating explanations is an important process for students, not only to make connections between novel information and background knowledge, but also to be able to communicate their understanding of any given topic. This article explores students' explanations in the context of computational science and engineering, an important interdisciplinary…

This study aimed to investigate the effects of augmented reality (AR) activities on students' academic achievement and motivation in a biology course. For this purpose, a mixed study was conducted, and a pretest and posttest control group model was used. In addition, the opinions of the experimental group students and the teacher about the AR…

Accurate self-evaluation is critical for learning. Calibration describes the relationship between learners' perception of their performance and their actual performance on a task. Here, we describe two studies aimed at assessing and improving student calibration in a first-semester introductory biology course at a 4-year public institution. Study…

The purpose of this study is to develop and evaluate Multi-frames Video Recorded Experiments (MFVREs) as self-learning materials for Electricity topic of the Malaysian Form Five Physics curriculum. The development of MFVREs consisted of eight steps; selecting topic, selecting related experiments, preparing apparatus and materials for experiments,…

The Program for International Student Assessment (PISA) by the OECD measures student study time during formal school periods and during periods of out-of-school-time (OST). The purpose of these items is to account for differences in country to country achievement levels. However, analyses of the impact of additional study time on student…
