S. Mohadjer et al.: Using paired teaching for earthquake education in schools 283 collaboratively by nine early career Earth and environmental scientists and educators from academic institutions across the United Kingdom and Germany. Many of the video pre- senters are experienced educators who have developed and taught science, technology, engineering, and mathematics (STEM)-related subjects and activities in both formal and informal settings, including K-12 schools. To create the series, we adapted the protocols for creating interactive videos by Larson and Murray (2017) and applied them to lessons plans developed by Mohadjer et al. (2010). These protocols incorporate the paired-teaching pedagogy (see Sect. 2.1) and blend well with the interactive exercises that accompany the lesson plans. For a thorough discussion on the protocols, we refer readers to Larson and Murray (2017). The video lessons are not intended to replace an existing curriculum but rather to support the teaching of concepts re- lated to earthquakes through interactive, hands-on activities and discussions that are guided by a guest scientist and the in-class teacher. In addition, the videos are developed for the global school community and do not target or adhere to the educational standards of a specific region or country. How- ever, teachers are encouraged to contextualize the curriculum content according to their local environment and are given relevant guidelines in the teacher segment at the end of each video (see the Supplement for more details). Below, we in- troduce the paired-teaching approach and describe our video evaluation strategy. 2.1 Paired-teaching pedagogy We used a pedagogical model known as paired teaching (or teaching duet) developed by the MIT (Massachusetts Insti- tute of Technology) BLOSSOMS (Blended Learning Open Source Science or Math Studies) initiative.

The evaluation rubric is after Steer et al., 2005 (left). 4 Discussion 4.1 Factors influencing students’ learning The differences between students’ pre- and post-assessment responses to survey questions were only significant above the 95 % level when they were asked to indicate if it was possible to know where earthquakes happen (Sect. 3.2.4), to sketch a cross section of the Earth (Sect. 3.2.1), and to identify non- structural hazards in example photographs (Sect. 3.2.3) (Ta- ble S2 in the Supplement). These results indicate that our paired-teaching videos appear to change students’ views and understanding of some concepts, including (i) the Earth’s in- terior for the Tajikistan group, (ii) earthquake location fore- casting for both the Tajikistan and UK groups, and (iii) non- structural hazards for the UK group.

290 S. Mohadjer et al.: Using paired teaching for earthquake education in schools the students’ views of earthquake prediction and forecasting. This information is important, since earthquake prediction or forecast, or lack thereof, may influence preparedness at- titudes and behaviours in some communities. Prior to video watching, approximately 60 % (23 Tajik students) said “no” to earthquake prediction (in terms of date and time) and “yes” or “sometimes” to earthquake forecasting (in terms of loca- tion). In contrast, these values for the UK group are lower (36 %; 14 students) and higher (77 %; 30 students), respec- tively. The only significant difference (95 % level) between the students’ pre- and post-answers was observed for the UK group for earthquake location forecasting. This may indicate that our curricular material (particularly the plate boundary classroom activity), which emphasizes that earthquake lo- cations are not random, was effective in changing students’ understanding of earthquake location forecasting. A notable portion of Tajik students (26 %; 10 students), however, mis- interpreted the survey question, as is evident in their irrele- vant responses to earthquake location forecasting (e.g. listing streets and schools as locations of earthquakes). 4.1.4 Non-structural hazards For both student groups, our non-structural hazard video in- creased the students’ ability to identify non-structural haz- ards in example classroom photos. However, the increase in hazard identification is significant (95 % level) only for the UK group. This could be due to lack of exposure to earth- quake shaking during which non-structural elements of a building can pose hazards to the building’s occupants. Hav- ing experienced earthquakes and being familiar with some hazards, Tajik students’ give similar responses before and af- ter video watching. 4.2 Teacher feedback 4.2.1 UK teacher feedback Both teachers found the curricular material to be presented clearly, to be appropriately geared to the level of their stu- dents, and to be valuable in helping students understand and Figure 7.
