Reisen von Europa nach Ostasien finden heute gewohnlich mit dem Flugzeug statt, und da gibt es nicht viel zu berichten. Dagegen war eine Reise mit dem Schiff im Jahre 1872 erlebnisreich, zumal der Reisende, der Arzt an der russischen Gesandtschaft in Peking, Emil Bretschneider (1833-1901), ein angesehener Sinologe und Botaniker, sich dafur drei Monate Zeit genommen hatte: Er wollte bei der Gelegenheit der Ruckkehr von seinem Urlaub Indien und Niederlandisch-Indien (das heutige Indonesien) kennenlernen. Seine Schilderungen von Land und Leuten und insbesondere der Vegetation sind lebendig und zuverlassig und lesen sich heute, nach hundertfunfzig Jahren, wie eine echte Zeit-Reise in die Vergangenheit. In Singapore war er Gast des Herrn Whampoa und wohnte in seinem zauberhaften Garten, in Buitenzorg (Bogor, Java) Gast des Generalgouverneurs, studierte die Flora in diesem altesten und angesehensten botanischen Garten Asiens und besuchte einige der schwer zuganglichen Vulkane. Der Reisebericht erschien in Form von Briefen in der Rigaschen Zeitung und ist heute praktisch unbekannt. Mit Einleitung und Register.

Fur die berufsbegleitende Professionalisierung von Lehrkraeften werden Fortbildungen eine zentrale Bedeutung zugesprochen (u. a. Richter et al., 2020, S. 147). Wenngleich Lehrkraefte eine grundsaetzliche Pflicht zur Fortbildung haben, ist diese in zahlreichen Bundeslaendern nicht quantifiziert, sodass es im Ermessen der Lehrkraefte liegt, ob und in welchem Umfang sie der Fortbildungspflicht nachgehen (Pasternack et al., 2017, S. 240). Bisherige Befunde weisen darauf hin, dass in der Fortbildungspraxis eine unzureichende Passung zwischen Angebot und Nachfrage besteht (u. a. Cramer et al. 2019, S. 43). Um die Lehrkraefteperspektive staerker einzubeziehen, kann das Interesse als zentraler Beweggrund fur die Fortbildungsteilnahme (u. a. Cramer et al., 2019, S. 80) sowie Praedikator fuer nachhaltigen Lernerfolg entscheidend sein (Schiefele & Schaffner, 2015, S. 160). An dieser Stelle setzt die Studie mit dem Ziel an, mittels einer empirischen Untersuchung das Interesse von Geographielehrkraeften an Inhalten und Taetigkeiten im Kontext fachspezifischer Fortbildungen sowie potenzielle Einflussfaktoren auf das Interesse zu ermitteln. Auf der Grundlage der Forschungsergebnisse werden Handlungsempfehlungen hinsichtlich der Gestaltung zukuenftiger Fortbildungen im Fach Geographie abgeleitet. Die empirische Umsetzung erfolgt mithilfe einer qualitativen Vorstudie in Form von leitfadengestuetzten Interviews (N=8) und einer quantitativen Hauptstudie in Form einer Online-Befragung (N=172).

Ti sei mai chiesto cosa sia lenergia nucleare e come funziona una centrale nucleare? Quante volte ne hai sentito parlare? Sai cosa siano le radiazioni, le scorie, lUranio arricchito, il Plutonio? Sebbene io non sia un esperto, grazie ad unapprofondita ricerca sul web e un minimo di conoscenze tecniche, sono finalmente riuscito a capire molte cose su questa fonte di energia che, da una parte, mi fa paura ma dallaltra, in un futuro prossimo, potrebbe essere la soluzione al surriscaldamento globale. Ho cercato di descrivere i vari concetti in modo semplice realizzando anche dei disegni rappresentativi per illustrare i componenti principali. Spero di aver esposto tutto in modo corretto. Una Centrale Nucleare e molto piu complessa di come lho illustrata ma leggendo questo libro capirai quali sono i principi fisici che la fanno funzionare, concetti come la fissione nucleare, il controllo dei reattori, la generazione di energia elettrica e potrai acquisire una conoscenza piu approfondita per comprendere meglio il suo funzionamento.

Le modalita di verifica delle conoscenze degli studenti, negli anni, si sono notevolmente evolute per adeguarsi a esigenze dovute a nuove organizzazioni didattiche. Cosi, in alternativa ai classici problemi e domande a risposta aperta si e diffuso lutilizzo di domande a risposta chiusa. Le prove a risposta chiusa (i test) sono un insieme di domande gia corredate da risposte tra cui scegliere quella corretta e sono utilizzati, sempre piu frequentemente, sia per valutare lidoneita alla frequenza di corsi universitari dei neo diplomati, sia per verificare le conoscenze acquisite nello studio di materie universitarie. Per fornire gli studenti un ausilio a questa metodologia desame nel 2003 ho preparato insieme al prof. Aldo Ricca il testo Chimica Guida a una valutazione critica Questo testo proponeva agli studenti per valutare la propria preparazione solo domande a risposta chiusa Ovviamente il rischio insito in questo tipo di valutazione e di disabituare, o non abituare, lo studente universitario a riflessioni speculative sulla materia e, pertanto, di non esaltare le capacita logiche che consentono collegamenti tra i diversi concetti acquisiti, che sono la base per una buona formazione professionale. Per minimizzare questo rischio le domande e le relative risposte erano state formulate in modo tale da costringere lo studente a utilizzare anche la logica e non soltanto le nozioni. Infatti, la maggior parte degli studenti tende, piu che a individuare la risposta corretta, a scartare le affermazioni errate. In questo modo se, anche nello scartare risposte errate, lo studente e costretto a utilizzare, oltre alle nozioni, anche concetti e capacita logiche, lo scopo di una corretta verifica e stato comunque raggiunto. In tutti i casi, lo studente medio si disabitua a organizzare le idee per dare risposte scritte che devono essere necessariamente puntuali e sintetiche e non acquisisce le capacita che gli permetteranno, un domani, di partecipare in modo corretto a discussioni di lavoro o di redigere una eventuale relazione scientificamente corretta e comprensibile. Per ovviare a quanto sopradetto, in questo nuovo testo, per ogni capitolo e stata aggiunta una parte con domande a risposta aperta, seguite da possibili risposte corrette. Sono stati aggiunti due capitoli trattando quindici argomenti della chimica di base dove ogni capitolo e diviso un quattro parti: nella prima sono formulate domande a risposta chiusa con annesse cinque affermazioni; nella seconda sono formulate domande a risposta aperta presenti nei temi desame dati nel corso degli anni nei corsi di Chimica del Politecnico di Milano nella terza parte tutte le affermazioni fatte nella prima parte (sia giuste, sia errate) sono discusse in modo critico mettendo in evidenza perche, se corrette, devono essere accettate o perche devono essere giudicate inaccettabili; nella quarta parte sono date le soluzioni o le risposte che uno studente avrebbe dovuto dare alle domande a risposta aperta. Tenendo presente che ad alcune domande e possibile rispondere in piu di un modo, le risposte date non sono le sole possibili. Ritengo che questo volume possa essere una guida utile sia per stimolare lapprendimento della Chimica sia per affinare le capacita critiche necessarie per un futuro e proficuo utilizzo delle conoscenze della materia. Ovviamente, lutilizzo di questa guida deve seguire lo studio di un testo di Chimica organi- camente svolto e organizzato. Infatti, per ogni capitolo e indicata una serie di conoscenze che si suppone siano gia state acquisite.

Preliminary Discourse on the Study of Natural Philosophy is a book by John F.W. Herschel. It delves into the general nature of physical sciences while expounding on the principles needed for scientif

Kulturell greift die Neuzeit im Abendland nach Uberwindung christlicher Dogmen auf das Vorbild der Antike zuruck, beginnt wieder zu forschen. Materiell setzt die Spatzeit Mensch und Natur in groerem Mastab ein, ausbeutend und im Sinne zivilisatorischen Fortschritts und Wohlstands. Das technische Zeitalter der Romer wiederholen wir seit 250 Jahren im Abendland, geraten aber durch Wachstum an Grenzen, in einen nicht umkehrbaren Klimawandel. Verheerende Folgen durch Emission, Raubbau und invasive Arten sind imstande, eine Zivilisation abzulosen. Naturgewalten leiten eine neue Ara ein, schlimmstenfalls oder bestenfalls ohne uns. Antike war ein Vorbild, aber das Abendland ist zu sehr auf Nutzen bedacht.

Im stets wachsenden Buchangebot uber Naturgarten gibt es kein Buch uber Naturgartner. Auf wenigen Bildern erkennt man undeutlich eine kauernde Gestalt, die in der Erde wuhlt; es konnte der Yeti sein oder Nessie bei der Eiablage, eben eines jener sagenumwobenen Geschopfe, deren tatsachliche Existenz nicht bewiesen ist. So ist es kein Wunder, dass in der Bevolkerung das Bild des Naturgartners von Mythen gepragt ist. Hier klafft in der Gartenliteratur eine Lucke, und Stefan Leszko beeilt sich, sie zu schlieen.
