In recent years, single-subject experimental courses have not been able to meet the demands of the comprehensive development of life sciences. This study is based on two fundamental disciplines, molecular biology and metabolomics, with the analysis and intervention of tumor-related genes as the starting point. A comprehensive experimental course…

In response to the global crisis of type 2 diabetes prevalence, this dissertation investigated the impact of a culturally sustaining, health-centric science curriculum contextualized in type 2 diabetes. Using a case study methodology, it explored how the curriculum shaped math and science preservice teachers' (PSTs) perceptions of science and how…

Collaborative learning methods are increasing in popularity as a way of improving student performance and involvement in undergraduate courses. For this study, a group quiz format was used in an attempt to improve course grades and engagement in an introductory meat science course. Six group quizzes and six individual quizzes were taken by 70…

The purpose of the study is to investigate how pre-service elementary teachers' orientation about science inquiry impacts their implementation of inquiry-based instruction. Teaching orientation is one of the levels of pedagogical content knowledge (PCK) which impacts on teachers' instructional practice. With thirty-one pre-service teachers, data…

Recent K-12 science reforms necessitate a shift in curriculum and instruction to support coherence from the students' perspective. This coherence emerges when students see their science work as addressing and making progress on their questions and problems. Storyline curricular units afford student coherence, but teachers need support to craft…

The purpose of this study was to assess the relative effectiveness of cooperative learning (CL) strategies on learners' peer relatedness, academic support (AS), and learning gains in Biology. A quasi-experimental non-equivalent group pre-test post-test design was employed, involving a sample of 81 students. Both quantitative and qualitative data…

Introduction: The aim of the study was to examine the effects on Primary School Teacher Candidates of developing and implementing jigsaw technique activities enriched with educational games in Science and Technology Teaching lessons. Methods: In the study, the mixed design was used. The single group pre-test post-test weak experimental pattern…

Socioscientific issues (SSI) have been found to improve scientific literacy skills among K-12 students. Elementary preservice teachers (PSTs), however, are reluctant to implement SSI due to a lack of confidence with content knowledge concerning SSI and pedagogical abilities. Existing research focuses on helping PSTs overcome these concerns through…

Research indicates that students frequently struggle to apply their knowledge of organic compounds' structural theory to understand the concepts related to resonance and learn to use curved arrows to write resonance structures. Educators have developed educational tools and methodologies to aid students in overcoming their learning difficulties.…

Given the big gap between rural areas and cities and developed areas of China in basic education, it is of great significance to train a large number of excellent teachers for basic education in the vast rural areas so as to boost basic education there and achieve educational equity. Hanshan Normal University is a regional normal university…

This study compared science instruction in STEM and non-STEM high schools to determine how implementing a STEM instructional design impacts science, a cornerstone of STEM curricula. The goal was to gain insight into how the STEM school structure influenced the implementation of the science curriculum. The multiple case study examined STEM…

This research aimed to provide an innovative chemistry learning material with guided tasks to improve students' competence in Chemistry. It involved 180 students enrolled in the Analytical Chemistry course at State University of Medan in academic year of 2016/2017. The samples were purposively selected and divided into two groups. The research…

We investigated the effects of a laboratory curriculum developed using the socio-­scientific issues (SSI) framework to contextualize scientific and socially relevant issues for students. Using self-determination theory and hierarchical linear modeling, we examined the effects of the SSI curriculum relative to a control curriculum on student…

Research suggests that it is challenging for elementary students to develop conceptual understanding of trait variation, inheritance of traits, and life cycles. In this study, we report on an effort to promote elementary students' learning of hereditary-related concepts through scientific modelling, which affords opportunities for elementary…

In December 2015, the Principia mission was launched and many schools took part in local or national activities associated with the Principia mission. Researchers at York undertook a three-year study to find out about the influence of human spaceflight on children's attitudes towards STEM subjects. Along with a large-scale survey, between November…
