Describing the progression of insects that arrive at a cadaver can be a useful and exciting tool for teaching students about complex concepts such as ecological succession.

The Y chromosome is of great interest to students and can be used to teach about many important biological concepts in addition to sex determination. This paper discusses mutation, recombination, mammalian sex determination, sex determination in general, and the evolution of sex determination in mammals. It includes a student activity that…

The National Research Council (NRC) has indicated that effective instruction in colleges of agriculture should prepare students to enter a dynamically changing workplace by helping students learn to be proficient in 21st century skills. The NRC suggested that effective instruction in colleges of agriculture should encompass a hospitable learning…

Subtraction has two meanings and each meaning leads to the different strategies. The meaning of "taking away something" suggests a direct subtraction, while the meaning of "determining the difference between two numbers" is more likely to be modeled as indirect addition. Many prior researches found that the second meaning and…

An activity involving analysis of art in biology courses was designed with the goals of piquing undergraduates' curiosity, broadening the ways in which college students meaningfully engage with course content and concepts, and developing aspects of students' higher-level thinking skills, such as analysis, synthesis, and evaluation. To meet these…

In this study, longitudinal cohort-sequential latent growth modeling was used to determine the effects of (a) socioeconomically mixed preschool and kindergarten classrooms, (b) the implementation of an education program aiming to accelerate socioeconomically disadvantaged children's emergent academic skills, and (c) the amount of teacher-managed…

The purpose of this analysis is to describe the variation in students' reports of engagement in science across science teaching and learning activities. In addition, this study examines student and school characteristics that may be associated with students' levels of engagement in science. Data are drawn from the Programme for International…

This quantitative research study reports the effectiveness of demonstrations supported by appropriate information and communication technology (ICT) tools such as dataloggers, animations and video clips on upper secondary school students' attitudes towards the learning of physics. A sample of 94 secondary four express stream (age 16 years) and…

This article reports on two projects: one that investigated the impact of school gardens on primary children's learning and one that is currently exploring the pedagogies involved in teaching children in the garden. The evidence presented suggests that school gardens can be an interesting and effective way of engaging children with learning, but…

Research Findings: Shared book reading provides a meaningful context for rich conversations to occur between a child and an adult and offers opportunities for children to be exposed to a range of vocabulary and concepts that often extend beyond their everyday experiences. Few studies have examined parent-child shared book reading as a context for…

Globalisation can facilitate improvements in health through the speed and ease of shared information, advances in health care delivery and health policy, and the enhanced pace of discovery through international research collaborations. However, there are associated potential risks to health such as the spread of communicable diseases and…

As English learners face the double demands of building knowledge of a second language while learning complex grade-level content, teachers must find effective ways to make challenging content comprehensible for students. This updated English learner practice guide, "Teaching Academic Content and Literacy to English Learners in Elementary and…

In this article I focus on the mediational role of communicative activity in the co-construction of meaning involved when pupils write collaboratively. I explore the developmental nature of peer intermental or social activity within a Zone of Proximal Development (ZPD) by drawing on perspectives from sociocultural theory and the dialogical aspects…

This study drew on data from a large, randomized trial of Cognitive Tutor Algebra (CTA) in high-poverty settings to investigate how mathematics curricula and classroom achievement related to teacher reports of time spent on inquiry-based and lecture-based mathematics activities. We found that teachers using the CTA curriculum reported more time on…

Problem Statement: Teaching a student critical-thinking skills has always been an important mission of social studies education. Over the years, literature and scholarly interest in critical-thinking in social studies have grown sporadically. Nevertheless, growing interest in the literature and commitment among the scholars did not ensure…
