Nurturing the ability to argue is of great importance in science education, despite students often encountering cognitive and emotional barriers. The aim of this study was to examine the quality of argumentation and the issues raised by secondary school students when they are asked to respond to structured argumentation tasks. We chose topics from two different socio-scientific issues of varied perceived relevance to students’ daily lives: the sale of fast food in school canteens (Group 1) and the addition of antibiotics in animal feed (Group 2). The study involved 249 high school students aged 14–16, in Poland. A total of 139 participants took part in an intervention about fast food, and 110 in an intervention about the use of antibiotics. Data were collected in the form of written arguments developed by students as part of a structured teaching intervention. Quantitative and qualitative methods were used to process and analyze the data. On average, students’ arguments scored higher on the topic of antibiotic use on animal feed. Qualitative content analysis of the students’ arguments identified four thematic groups: (1) personal aspects revealing personal meanings, values, and defence mechanisms; (2) scientific aspects revealing substantive knowledge; (3) socio-cultural aspects revealing economic, sociological or cultural aspects; (4) nonsensical or incoherent arguments. A topic related to students’ personal decisions and perceived to be closest to their lives and daily experience (eating fast food in the school canteen) more often prompted arguments indicating cognitive defence, by denying the harmfulness of fast food and emphasizing possible advantages or appealing to the right to choose. Based on this finding, we discuss the need for defence mechanisms to be considered in pedagogical designs for the teaching of argumentation.

In this study, we identify the pedagogical practices the science teachers use for successfully conducting their argumentation-based science lessons and examine the process of managing informal formative assessments. For this qualitative study, we collected data via video and audio devices from classroom implementations after conducting two professional development courses on assessment practices in inquiry settings and argumentation in science classrooms. We analysed the data from the conversation analysis (CA) perspective to conduct a data-driven study. Our results show that there are multiple pedagogical practices that teachers use to achieve lesson purposes and shape lessons. These are primarily the revealing of different claims and warrants or counterarguments about the same phenomenon or situation, prompting the class to discuss different arguments, including more than one student in interaction. Regarding the nature of answers produced by students, the teachers also make implicit or explicit positive and negative assessments, avoid explicit assessments, and give content feedback as pedagogical practices and use them for managing the informal formative assessment process. The results show that the teachers perform some pedagogical practices via the information gained by the informal formative assessment process. These pedagogical practices provide them with new road maps to achieve the lesson goal by increasing classroom interactions.

Abstract Debates have long been an effective educational method in various fields, including argumentation education. In debates in which participants are divided into affirmative and negative sides, engagement in argumentation is heightened. Numerous studies have attempted to demonstrate this, but the question of whether participation in debates leads to increased argumentativeness, or whether individuals who engage in debates inherently have a higher orientation towards argumentation, remains unresolved. In the present study, debates were conducted for 15 weeks, and argumentativeness was measured using pre-and post-tests. The results confirmed that debate participation increases argumentativeness. Furthermore, while previous research has mostly focused on argumentativeness in the first language, the present study deepens the relationship between argumentativeness in both first and second languages. Specifically, focusing on Japan, where the first language (Japanese) is high-context and the second language (English) is low-context, this research clarifies the relationship between argumentativeness in the first and second languages, as well as the impact of debate.
