Productive struggle is a process in which students expend effort to grapple with perplexing problems and make sense of something that is not immediately apparent and beyond their current level of understanding and capacity. The experience encourages students to reflect on and restructure their existing knowledge toward a new understanding of…

In the present research, the "DNA Model with Clothespins" activity was designed to teach the subjects of nucleotide, DNA, and DNA replication, which are abstract subjects of science. The aim of the research, which was carried out with 20 students in 8th grade, was to examine the effects of the activity on students' achievement on the…

The aim of this study is to determine the evaluations of eighth grade gifted students towards cloning and to examine the argument structures formed by gifted students. The study was carried out using a case study design, which is one of the qualitative research method designs. The study group of the research consists of 24 gifted students studying…

Mendelian genetics are essential for students seeking to comprehend the complexities of inheritance; although fundamental, these biology concepts are difficult for students to understand. This study examined the effectiveness of task-based learning (TBL) in enhancing the students' conceptual understanding of the Patterns of Mendelian Genetics. A…

In recent years, countries have focused specifically on improving thinking skills in their science education programs. One of the science lesson methods that can be used to activate the use of thinking processes is scientific scenarios. In this direction, the aim of the study is to investigate the effect of socioscientific subject-based…

Teachers are highly reliant on textbooks for teaching. In the Republic of Korea, science textbooks help students to understand scientific terms through inquiry activities. However, there is a lack of analysis on whether the inquiry activities suggested in these textbooks appropriately cover the terms included in the main text. Therefore, this…

This study aimed at designing instructional material named Biotechnology Instruction Module (BIM) which is enriched with active learning methods to enhance the 8th grade students' learning of the topic. The development of the teaching materials proceeded within the stages of the ADDIE instructional design model. The final form of the instructional…

This study investigated the causes of modifications on "Tradescantia zebrina" leaves due to environmental effects by inquiry-based and long-term observations. These observations started with restricted face-to-face education at school during the COVID-19 and continued under the teacher's guidance in distance education. All the study…

When people are exposed to information that leads them to overestimate the actual amount of genetic difference between racial groups, it can augment their racial biases. However, there is apparently no research that explores if the reverse is possible. Does teaching adolescents scientifically accurate information about genetic variation within and…

Conflation of sex and gender is implicated in the development of essentialist thinking, which has been linked to the justification of systems of prejudice in modern society. This exploratory study presents findings from a person randomized control trial conducted with 460 students in 8th-10th grade that investigated the extent to which students…

This study explores one teacher's instructional method for teaching life sciences using argumentation and argumentative writing rather than simple templates for writing claims and evidence. The microethnographic discourse analytic case study reported here included the teacher and 26 "advanced" eighth-grade students in a suburban middle…

The aim of his study was to detect the misconceptions about heredity in secondary school (Middle school) 8th Grade pupils' Science courses. In order to perform a beneficial and useful science education it was necessary. The space of study was 8th grade pupils that the data obtained from research assessed via appreciated statistical methods.As a…

The present study used a genetically informed design of twins raised in the same family (375 monozygotic and 290 dizygotic twins; 50.2% girls) to examine the association between adolescents' genetic risk for depressive symptoms and the course of the parent-child relationship quality throughout adolescence. Depressive symptoms and the quality of…

This practical lesson describes how students in six eighth grade science classes participated in a lesson combining the National Core Arts Standards with the Next Generation Science Standards. The goal of the lesson was to provide visual representations of finch beak form and function so students could better understand genetic variation and how…

The purpose of this study is to investigate the effects of case teaching on how students learn about genetic engineering, in terms of meaningful learning and retention of learning. The study was designed as quasi-experimental research including 63 8th graders (28 boys and 35 girls). To collect data, genetic engineering achievement tests were…
