Modelling in the scientific approach to teaching life and earth sciences: Views and practices of Moroccan teachers

Modeling is a fundamental tool in the teaching and learning processes of life and earth sciences. It serves as an investigative instrument that enables students to test hypotheses and solve scientific problems. This paper presents the findings of a survey conducted among 96 Moroccan life and earth sciences teachers teaching students at the primary, junior high and high school levels. The study aims to highlight the role of modelling in life sciences instruction and explore teachers' understanding, approaches and perceptions towards models and modeling practices. A questionnaire-based methodology was employed to collect data on teachers' awareness of the significance of models in life sciences and the instructional approaches that are adopted in these models. The findings reveal Moroccan teachers' clear grasp of models' significance in teaching life sciences. Moreover, they employ similar approaches to models and modeling practices. The research highlights instructors' awareness of models' potential to increase the effectiveness and appeal of scientific instruction. It establishes modeling's pivotal role in instructing life sciences, emphasizing the need to incorporate modeling activities into the curriculum to nurture students' scientific inquiry and problem-solving skills. The study's practical implications suggest the value of training programs and professional development initiatives for teachers to promote model use in life sciences instruction. Enhancing teachers' knowledge and pedagogical strategies related to modeling can enrich science education leading to increased student engagement and achievement in the life sciences.

GIS for Earth Sciences

Geographic Information Systems (GIS) supports data collection, geospatial data analysis, visualization, scientific communication and research collaboration. GIS has implications for many fields of the Earth Sciences, which are above and beyond one's imagination. Since the development of the first computerized GIS in the 1960s, the need by professionals for geospatial technology in fields that utilize geospatial data has never stopped expanding. As noted by a market analysis in August 2017: “The GIS Market was valued at USD 5.33 Billion in 2016 and is expected to reach USD 10.12 Billion by 2023, growing at a compound annual growth rate of 9.6% between 2017 and 2023” (marketsandmarkets.com, August 2017). Earth Sciences encompasses a broad and diverse array of technical areas, such as geology, geomorphology, geography, geophysics, hydrology, hydrogeology, environmental sciences, oceanography, meteorology, and atmospheric sciences. All of these fields use geospatial data to solve complex problems related to the planet Earth. Some of these problems are near impossible to solve without the use of GIS. This article presents a brief introduction to GIS and examples of its applications to the Earth sciences. Three case studies highlight the utility of GIS applications in compiling, integrating, analyzing and visualizing geospatial data.
