Teachers often struggle to facilitate open discussions about evolution when they perceive it to be at odds with cultural and religious norms. Little is understood about classroom discourse and teacher-student interactions during the teaching of evolution. This study analyzed classroom discourse and teacher-student exchanges in a 10th-grade biology…

"What if…?" is a four-day summative assessment for a unit on biodiversity and evolution within a general biology course for ninth and tenth graders. Students gather evidence through multiple investigations to answer the questions: (1) "How has life changed on the planet? (2) What has caused those changes? and (3) What is happening…

Understanding natural selection requires mentally linking various key concepts and processes. Many students find it difficult to construct scientific explanations about natural selection and might display misconceptions. Our study aimed to investigate the understanding of natural selection and the existence of teleological or other misconceptions…

Though argumentation is a key component of scientific knowledge construction practices, it rarely occurs in classrooms worldwide. Moreover, related literature in the context of genetics and evolution learning primarily addresses them separately. In contrast, this paper is part of broader research on genetics and evolution instruction taught…

The topic of natural selection presents challenges to high school students since it requires understanding of an emergent process, which is a missing schema for most students. Many interventions for teaching natural selection have limited effect in bringing about substantial ontological conceptual change. This study evaluates the effectiveness of…

Evolutionary theory constitutes the overarching concept in biology. There is hardly any other concept that is more complex, and causes more difficulties in learning and teaching. One instructional approach in optimizing the learning of complex topics is to use worked examples combined with self-explanation prompts that fit to the prior knowledge…

While school textbooks are assumed to be written for and used by students, it is widely acknowledged that they also serve a vital support function for teachers, particularly in times of curriculum change. A basic assumption is that biology textbooks are scientifically accurate. Furthermore, because of the negative impact of…

One major emphasis of reform initiatives in science education is the importance of extended inquiry experiences for students through authentic collaborations with scientists. As such, unique partnerships have started to emerge between science and education in an ongoing effort to capture the interest and imaginations of students as they make sense…

The biological community is currently undertaking one its greatest scientific endeavours, that of constructing the Tree of Life, a phylogeny intended to be an evidenced-based, predictive road map of evolutionary relationships among Earth's biota. Unfortunately, we know very little about how such diagrams are understood, interpreted, or used…

The purpose of this study was to detect the extent to which contextual material of a unit on "The origin and evolution of living organisms" included in the high-school biology curriculum in Jordan affected students' acceptance of the theory of evolution. The participants of this study consisted of 107 tenth-grade students randomly drawn…

High school biology teachers face many challenges as they teach evolution. State standards for evolution may provide support for sound evolution instruction. This study attempts to build upon previous work by investigating teachers' views of evolution standards and their evolution practices in a state where evolution standards have been…

Changes in high school students' (n = 94) conceptions of natural selection were examined as a function of motivational beliefs (individual interest, academic self-efficacy), basic prior knowledge, and gender across three assessments (pre, post, follow-up). Results from variable-centered analyses suggested that these variables had relatively little…

A tenth grade class in an international school studied evolution for four weeks as part of the study of Biology. A diagnostic test was used to determine the main misconceptions students have as they come to the study of evolution. This was followed by a series of explorations of different conceptual models to account for evolution, structured…

Evolutionary and biological approaches tend to suggest that social dominance is predominately an aspect of male social organization. Furthermore, when females behave non-normatively, they are less positively evaluated than males engaging in the same behavior. Alternate, less familiar models of females and dominance/aggression underlie the present…

Although many research studies report students' Lamarckian misconceptions, only a few studies present learning and teaching strategies that focus on the successful development of the concept of natural selection. The learning and teaching strategy for upper secondary students (aged 15-16) presented in this study conducted in The Netherlands is…
