Im Sommersemester 2022 wurde erstmalig die Lehrveranstaltung „Chemieunterricht für heterogene Lerngruppen“ angeboten. Diese Lehrveranstaltung ist im Rahmen von PSI-Potsdam im Schwerpunkt „Inklusion und Heterogenität“ entstanden. Die Lehrveranstaltung wurde synchron online durchgeführt. Die Studierenden erhielten viele Möglichkeiten zur Diskussion sowie zur selbstständigen Erstellung von Unterrichtsmaterialien. Zum erfolgreichen Abschluss des Moduls erstellten die Studierenden ein Portfolio zu einem selbst gewählten Thema. Die Lehrveranstaltung wurde von den Studierenden sehr gut bewertet.
Das Konstrukt des erweiterten Fachwissens für den schulischen Kontext, welches in der ersten Förderphase von PSI-Potsdam entwickelt wurde, diente als Grundlage für die Entwicklung von Aufgaben, Lehrformate sowie einem Laborpraktikum im Bereich organischer Chemie. Eine Delphi-Studie wurde zur Validierung der Anwendung des Konstruktes auf die organische Chemie durchgeführt. Alle Aufgaben und Lehrformate wurden in Mixed-Methods-Studien evaluiert. Es zeigte sich, dass die Studierenden sowohl die Aufgaben als auch die Lehrformate und das Praktikum als relevant für ihren späteren Beruf als Chemielehrkräfte bewerteten.
Stepped supporting tools were developed and used in the university seminar Organic Chemistry taken by nonmajor chemistry students, which supported self-regulated learning. These supporting tools were also used for accompanying homework, which included a QR code that led to additional supporting tools. The application of stepped supporting tools in the seminars was evaluated by a four-item Likert scale. The students assessed the tools as a helpful instrument for solving tasks in chemistry.
Einleitung: PSI-Potsdam
(2018)
Die Entwicklung von Aufgaben zum „Erweiterten Fachwissen für den schulischen Kontext“ für Lehramtsstudierende wird vorgestellt. Die Kriterien für die Erstellung der Aufgaben werden an Beispielaufgaben erläutert. Der Einsatz der Aufgaben in den Übungen zur Vorlesung „Organische Experimentalchemie I“ wird evaluiert und diskutiert.
In this paper, we describe a study on tasks following the construct of school-related content knowledge. We know from previous studies that such tasks were rated by the preservice chemistry teachers as important for their future profession. Those studies were conducted in a traditional course on organic chemistry which was organized around chemical families. Therefore, we used and evaluated the tasks again in a new course on organic chemistry which is organized around basic concepts in organic chemistry. The results of this evaluation show that the students rate the tasks equally well but use other arguments for their rating. They do not focus only on the content of the tasks and whether this content belongs to the school curriculum or not. The students of the conceptual course rated the content more often (95%) as important for their future profession compared with the students in the traditional course (57%). Both groups of students rated the importance of the nature of the task the same way.
In this communication the development of an online course on the topic organic chemistry for nonmajor chemistry students is described and discussed. For this online course, the existing classroom course was further developed. New elements such as podcasts, task navigators, and a forum for discussing the solving of tasks or problems with the content were added. This new online course was evaluated. Therefore, a questionnaire was developed. This consists of questions with regard to the longtime learning behavior of the students and to the online learning. The results of this evaluation show that a preference for online learning and a preference for classroom teaching can be measured separately in two scales. Students values on the scale representing a preference for online learning correlate positively and significantly with confidence in the choice of the study subject, enthusiasm about the subject, and the ability to organize their learning, learning environment, and time management. They correlate also with the satisfaction concerning the materials provided. Students values for one of those teaching methods also correlate with their rating with regard to their exam preparation. Values representing a preference for online teaching correlate positively with students better feeling of exam preparation. Values representing a preference for classroom teaching show negative correlations with the values representing students similar or even better preparation for the exams as a result of online teaching. It is therefore not surprising that the ratings for the two scales correlate with the wish for a combination of online teaching and classroom teaching in the future. As a solution, a new course concept for the time after the corona virus crisis that suits all students is outlined in the outlook.
