Although research has addressed the quality of teachers' diagnostic competencies in recent years, it is not very clear how to foster these competencies effectively in the course of prospective teachers' university education. Research suggests that simulations with instructional support are promising tools for fostering complex competencies. We have developed a simulation that aims at measuring and fostering prospective primary school teachers' competencies to assess students' mathematical abilities and misconceptions based on their written task solutions. In this study, we analysed data from prospective primary school mathematics teachers who used one of three different versions of the simulation. Two versions contained a specific type of scaffolding, while the third version did not contain scaffolding. Specifically, the two scaffolding types were <i>content-related scaffolding</i> that emphasized the use of specific pedagogical content knowledge, and <i>strategic scaffolding</i> that emphasized diagnostic activities. The results suggest that integrating scaffolding into the simulation did not substantially influence participants' overall perception of the simulation regarding presence, authenticity, or perceived cognitive load. Compared to participants in a control group without intervention, participants who used the simulation with scaffolding had higher diagnostic accuracy regarding overall assessment of students' competence level. However, only content-related scaffolding but not strategic scaffolding or no scaffolding tended to improve participants' competence in identifying students' specific misconceptions. The results provide a first empirical basis for further development of the simulation.</p>","PeriodicalId":43968,"journal":{"name":"Journal fur Mathematik-Didaktik","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9328016/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9490959","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Planning suitable solution methods is key to flexibility, a desired skill for equation solving. Comparing solution methods has been shown to foster flexibility. To support the learning benefits of the comparisons, productive classroom talk, which includes the discussion of different solution methods, is recommended. This study examines whether discussions that compare multiple methods include more planning processes than discussions that do not compare multiple solution methods or that are just about one solution method. The content analysis is based on utterances from 172 lessons from 43 classrooms in grades 9 and 10. The hypothesis is tested both <i>across classes</i> using binary logistic regression models and <i>at the class level</i> using paired samples t‑tests. The results show that planning processes are addressed about twice as often when comparing multiple solution methods.

Thus there is a need for appropriate instruments to evaluate the quality of the planning, implementation, and reflection process for mathematical learning opportunities in kindergarten. Existing instruments tend to focus on micro-adaptive learning support (MI-ALS), which considers the interaction between the professionals and the children. The quality of macro-adaptive learning support (MA-ALS), the teachers' planning of and reflection on learning opportunities, has yet to be comprehensively investigated. MA-ALS is important for the acquisition of subject-related (mathematical) competence, an aspect of kindergarten education that is gaining in importance in the pre-school curricula of many countries.The quality of mathematical learning support in kindergarten is conceptualized by differentiating between the quality of MA-ALS and MI-ALS. MI-ALS is also divided into general support (group management, emotional warmth) and subject-related support (learning stimulation, subject-specific language). A rating tool for analyzing the quality of mathematical learning support is presented and its psychometric quality is assessed. The tool is then used to analyze the teaching quality in two guided play situations (recorded) and two interviews each with 145 education professionals in Germany and Switzerland. A confirmatory factor analysis (CFA) confirms the validity of the distinction between group management, emotional warmth and subject-related support. The relationship between the level of MI-ALS and MA-ALS, the training of the teachers (academic vs non-academic), and the educational context (Germany vs Switzerland) is examined. The results corroborate the importance of including planning and reflection as a dimension of learning support quality.</p>","PeriodicalId":43968,"journal":{"name":"Journal fur Mathematik-Didaktik","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9580269/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40568895","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
