The aim of this article is to contribute to an articulated language of knowing, which we consider as a key aspect of teachers' professional work. We describe three examples of how the meaning of knowing some speciic learning objects can be studied and described. The three learning objects are: to be able to evaluate technical solutions, to be able to perform a house-hop and to be able to act with presence. Phenomenographic analyses of data from the pre-tests carried out within the frame of so called Learning Studies resulted in descriptions of different ways of knowing as well as different aspects of the speciic knowns that must be discerned in order to develop the knowing. Cet article a pour objectif de contribuer à un langage articulé du savoir, que nous considérons comme un aspect central du travail des enseignants. Nous décrivons trois exemples de la manière dont on peut étudier et décrire le sens du savoir dans le cadre d'objets d'apprentissage spéciiques. Les trois objets d'apprentissage sont : la capacité à évaluer des solutions techniques, la capacité à effectuer une igure appelée « house-hop » et la capacité à agir « avec présence ». Les analyses phénoménographiques des données issues des tests préliminaires qui ont été menés dans le cadre des études sur l'apprentissage ont permis de mettre en exergue différentes formes de savoirs ainsi que différents aspects des connaissances spéciiques que l'on doit discerner ain de construire le savoir.

Within the field of technology education, evaluating technical solutions is considered as an important topic. Research indicates that pupils have difficulties in evaluating technical solutions in terms of fitness for purpose, i.e. how effective a technical solution supports its intended function. By using the learning study, which is an iterative and collaborative research approach, the study explores the capability to evaluate technical solutions in terms of fitness for purpose, what it takes to know it and how to best enhance its learning in the primary technology classroom. Audio and video recorded interviews, teachers' meetings and lessons are the base data for the study. A contribution of the study is the understanding of this specific knowing, and what is critical for learning and thus to an improvement of technology teaching practice.

Purpose – Knowledge concerning the meaning of the object of learning is an important contribution of Learning study. The purpose of this paper is to generate this kind of knowledge and show how it can be developed and refined in the different phases of a Learning study. Design/methodology/approach – The paper reports on a Learning study in primary technology education conducted with students aged six to seven years old, with the aim to explore a specific object of learning; to construct a linkage mechanism for transferring and transforming movement. Findings – The findings show several aspects to discern by the learner in order to grasp the object of learning and reveal how this knowledge was gradually developed during the Learning study. The presumed aspects, those identified in the pre- and post-test, as well as how they were elaborated in the lesson contributed to refining the meaning of the object of learning. Originality/value – In Learning study, knowledge concerning the meaning of the object of learning is generated. By empirically demonstrating the development and specification of this knowledge during a Learning study, this paper will contribute to the discussion of knowledge products from Learning studies as well as to knowledge concerning what there is to know in order to develop a specific capability in technology education.
