Most chemistry students struggle with interpreting and understanding NMR (nuclear magnetic resonance) spectra and the general concepts of NMR spectroscopy. NMR spectroscopy seems to be difficult to both teach and learn. Therefore, the corresponding courses should be investigated in more detail. We conducted a survey with N = 39 German university…

The Energy and Momentum Conceptual Survey (EMCS) is a multiple-choice survey that contains conceptual problems involving a variety of energy and momentum concepts covered in a typical introductory physics course for science and engineering majors. Prior studies suggest that many concepts on the survey are challenging for introductory physics…

Student learning in simple electric circuits has been an important area in physics education research. This study builds off a previous investigation that applied the conceptual framework model to examine knowledge integration in student learning of simple electric circuits and developed a multiple-choice concept test for assessing knowledge…

The purpose of this research was to investigate the effect of simulation-supported inquiry-based learning on pre-service teachers' conceptual understanding of capacitors. The participants consisted of 50 pre-service teachers studying at a state university in Turkey. The participants were divided into two groups of 25 each on the basis of their…

A quasi-experimental treatment control group design was used to investigate the effect of a conceptual change curriculum, Multi-Step Inquiry approach, on students' perception of their learning in a science classroom. This started with the development of a workbook that explicitly focused on conceptual understanding, followed by the development and…

General Chemistry is a course where students are expected to nurture the development of their fundamental concepts in chemistry. Students begin general chemistry with alternative conceptions about the topics and fragmented knowledge structures. Majority of students who successfully complete the general chemistry course sequence continue to hold…

The concepts of the Coriolis and the centrifugal force are essential in various scientific fields and they are standard components of introductory physics lectures. In this paper, we explore how students understand and apply concepts of rotating frames of reference in the context of an example lecture demonstration experiment. We found in a…

This study assessed the impact of an "active learning" strategy employed alone or in combination with traditional lectures on the learning of mammalian physiology by undergraduate students. The study investigated the impact of three teaching strategies, namely (1) traditional lecture, (2) group discussion alone, and (3) combination of…

The effect of class size on student learning has numerous policy implications and has been a major subject of conversation and research for decades. Despite this, few studies have been done on class size in the context of university settings or physics courses. This dissertation helps address that gap in the literature by quantitatively analyzing…

A qualitative pre-/post-test case study was conducted to explore the influence of inquiry-based education in eliciting learners' understanding of the particulate nature of matter in the gaseous phase. Two grade four classes (n=116) were conveniently and purposively sampled from two farm schools in Pretoria, South Africa. Data was collected through…

Primary school students have trouble grasping concepts related to plants. Their misconceptions are also notable. On the other hand, mobile devices (such as tablets) and their apps, are considered effective educational tools. For examining whether the same holds true in relation to plants, we carried out a project, having as a target-group 263…

Problems with understanding concepts and mechanisms connected to plant movements have been diagnosed among biology students. Alternative conceptions in understanding these phenomena are marginally studied. The diagnosis was based on a sample survey of university students and their lecturers, which was quantitatively and qualitatively exploratory…

Teaching approaches in some school are still concentrating on memorizing. Teachers have to make the learning is meaningful for the students. One of the alternative tools is by using Brain-Based Learning. The purpose of this study is to investigate the effect of Brain-Based Learning on students' concept mastery in learning electric circuit for…

The study determined the effect of instructional scaffolding strategy on senior secondary school Biology Students' academic achievement and retention of concepts. Two research questions and two hypotheses were formulated for the study. Quasi-experimental research design involving pre-test, the post-test control group was employed. The population…

Recently, there have been many calls for an increase in instruction on the nature of science (NOS) in schools (i.e. NRC, 1996; NGSS Lead States, 2013). These calls recognize the importance of this topic at all levels of science education, but there is little guidance in terms of how to address it effectively in curricula. Similarly, there have…
