2024年6月19日下午，北师大SSI-L项目合作校首都师范大学附属育新学校成功举办了SSI-L合作研究项目的研讨会。北师大SSI-L项目学科指导专家北京教科院耿申研究员、北京师范大学第二附属中学物理特级教师彭梦华与项目办成员，以及首都师范大学附属育新学校SSI-L项目团队教师出席会议。
会议中，首都师范大学附属育新学校课程中心的唐枫主任、初二项目组教师焦健健、李萍等就本校“甜蜜诱惑——如何看待饮料？”这一社会性科学议题课程进行了深入的研讨。首先，唐主任详细阐述了《甜蜜诱惑》课程的整体框架、以任务为驱动的问题设计，以及初步的课程规划。课程初期将给予学生充分的自主权，鼓励他们自主提出问题、交流讨论、制定方案并尝试解决问题。对于后续课程设计，耿申强调了在议题设计中与课标、学情紧密结合的重要性，并明确界定了课程的主题领域，即健康、经济和环保。其中，饮料与健康作为核心主题，将作为课程讨论的重点。随着讨论的深入，课程将逐渐拓展至经济社会和环保等领域，以增强学生的社会责任感。耿老师还指出，课程设计中需充分考虑学生的知识年龄和认知水平，提倡以生成式的方式推进课程设计。
有关议题的争议性，耿老师与学校教师团队进行了深入的交流和探讨。他建议让学生提出具有争议性的问题，并引导学生深入交流和参与活动设计。同时，他也提出了一些具体的争议性问题，如“无糖饮料是否比有糖饮料更健康？” “鲜榨果汁与直接食用水果哪个更好？”以及“食品添加剂的使用是否安全？”等。唐主任则结合夏季瓶装饮料瓶垃圾增多的现象，提出了“鲜榨饮料与瓶装饮料哪个更环保？”“饮料可回收对环境的影响”以及“一次性包装与可回收包装哪个更合适？”等议题，这些议题旨在引导学生从多个角度思考问题，并鼓励他们创新性地寻找解决方案。
科学建模作为国际科学教育界提议的重要科学实践，在本次研讨会中也得到了充分的关注。SSI-L项目办刘阳丹指出，学生在日常生活中初具一定的认知模型，通过学习、调研和实验等活动，他们可以不断推翻、修改和完善这些认知模型，以进一步科学解释现象或解决问题，这对于培养学生的科学素养和实践能力具有重要意义。此外，刘老师提议，让学生以复刻爆款饮料为任务，通过奶茶店调查、资料搜集和实验等方式，以小组为单位动手制作一款相似的饮料。在此过程中，学生需要综合考虑健康、成本和安全等因素，并撰写报告和进行测评分析。
最后，唐主任提出了以辩论、角色扮演和圆桌论坛等方式作为课程的结课活动。这些活动旨在鼓励学生站在不同角度表达观点，并尝试列出健康清单进行综合评分。在不禁止饮用饮料的前提下，学生将学会如何选择更健康的生活方式以实现健康生活的目标。

On the afternoon of June 19, 2024, the Yuxin School Affiliated to Capital Normal University, the BNU SSI-L project partner school, successfully held a seminar on the SSI-L collaborative research project. Geng Shen, the BNU SSI-L project disciplinary guidance expert and researcher of the Beijing Academy of Educational Science, Peng Menghua, a special-rank physics teacher of the Second High School Attached to BNU, members of the project office, and teachers of the Yuxin School SSI-L project team attended the meeting.
During the meeting, Tang Feng, director of the Curriculum Center of Yuxin School, Jiao Jianjian and Li Ping, teachers from the eighth-grade project team, had an in-depth discussion on the school’s SSI course “Sweet Temptation – How to View Beverages?” First, Tang elaborated on the overall course framework, the task-driven problem design, and the preliminary course planning. In the early stage of the course, students were given full autonomy to encourage them to raise questions, exchange ideas, develop plans and try to solve problems. For the subsequent course design, Geng Shen emphasized the importance of integrating issue design with the curriculum standards and students’ learning conditions. He also identified the scope of the subject area for the course, which is health, economy and environmental protection. Among them, beverages and health, as the key theme, will be the focus of course discussion. As the discussion further develops, the course will gradually expand to fields of economy, society and environmental protection, so as to enhance students’ sense of social responsibility. Geng pointed out that the students’ knowledge age and cognitive level should be fully considered in the course design. It was advocated to promote the course design in a generative way.
Regarding the controversial nature of the issue, Geng had an in-depth exchange and discussion with the school’s teaching team. He suggested allowing students to raise controversial questions, have in-depth exchanges, and participate in activity design. Meanwhile he also put forward a number of specific controversial questions, for instance, “Are sugar-free beverages healthier than sugary ones?” “Which is better, freshly squeezed juice or directly having fruits?” “Is it safe to use food additives?” etc. Combined with the phenomenon that the amount of waste bottles generated from bottled beverages increases in summer, Tang Feng raised several issues, such as “Which is more environmentally friendly, freshly squeezed beverages or bottled ones?” “The impact of beverage recycling on the environment” and “Which is more suitable, disposable packaging or recyclable packaging?” These issues are intended to guide students to think about problems from multiple perspectives and encourage them to find solutions innovatively.
Scientific modeling, as an important scientific practice proposed by the international science education community, also received full attention in this seminar. Liu Yangdan, from the SSI-L project office, pointed out that certain cognitive models begin to take shape in students’ daily lives. Through activities such as learning, research and experiments, they might constantly overturn, modify and improve these cognitive models to further explain phenomena scientifically or solve problems. This is of great significance for developing students’ scientific literacy and practical ability. In addition, Liu proposed that students should be tasked with replicating popular beverages and making a similar beverage in groups through the approaches of milk tea shop surveys, data collection and experiments. In this process, students need to take overall consideration of multiple factors such as health, cost and safety, and then write reports and conduct evaluation analysis.
Finally, director Tang proposed using debates, role-play and round-table forums as the end-of-semester activities for the course. These activities are designed to encourage students to express their views from different perspectives and try to make health lists for comprehensive scoring. With the prerequisite of not prohibiting drinking beverages, students will learn how to choose a healthier lifestyle to achieve the goal of a healthy life.
