AbstractResearch on mathematical problem solving has a long tradition: retracing its fascinating story sheds light on its intricacies and, therefore, on its needs. When we analyze this impressive literature, a critical issue emerges clearly, namely, the presence of words and expressions having many and sometimes opposite meanings. Significant examples are the terms ‘realistic’ and ‘modeling’ associated with word problems in school. Understanding how these terms are used is important in research, because this issue relates to the design of several studies and to the interpretation of a large number of phenomena, such as the well-known phenomenon of students’ suspension of sense making when they solve mathematical problems. In order to deepen our understanding of this phenomenon, we describe a large empirical and qualitative study focused on the effects of variations in the presentation (text, picture, format) of word problems on students’ approaches to these problems. The results of our study show that the phenomenon of suspension of sense making is more precisely a phenomenon of activation of alternative kinds of sense making: the different kinds of active sense making appear to be strongly affected by the presentation of the word problem.

Strategies have been far more widely researched in conference interpreting than in the interactional setting of public service interpreting (PSI), although studies of the latter by Wadensjö and other authors suggest a strategic rationale for certain types of rendition (especially non-renditions). The present article describes an exploratory, qualitative study, based on roleplay, to identify strategies in PSI: the roleplays were designed to incorporate a variety of ‘rich points’, coinciding with peak demands on the interpreter’s problem-solving capacities and therefore particularly relevant to empirical study of interpreting strategies. Five interpreter-mediators with the Chinese–Spanish/Catalan language combination were each asked to interpret three different dialogues, in which the primary participants’ input was a re-enactment of real situations. Analysis of the transcribed video recordings was complemented by a preliminary questionnaire and by retrospective interviews with the interpreters. Their strategies, classified according to whether the problems concerned were essentially linguistic or involved the dynamics of interaction, in some cases reflect priorities typically associated with intercultural mediation. The advantages and limitations of using ‘rich points’ and roleplays in the study of interpreting strategies are briefly discussed

<p>Analogical reasoning is the ability to solve problems by finding similarities between two objects, namely source and target objects. The purpose of this study was to determine the analogical reasoning profile of students at SMA N 16 Semarang. This study is included in a qualitative study with data collection techniques used in surveys by working on analogical reasoning problems. The research subjects were 100 students of class X. The results found in this study were the category of analogical reasoning ability of students of SMA N 16 Semarang low with a frequency of 74 and a percentage of 73.6%. The low ability of analogical reasoning students is influenced by the lack of learning methods that encourage students in problem-solving using analogies, besides analogies have two sides if understood will facilitate students' understanding of concepts, but if it cannot be understood misconceptions occur so teachers rarely use analogous reasoning in explaining material abstract. Therefore it is necessary to have an understanding and experience of the teacher to build this ability by using learning methods that support analogical reasoning abilities.</p>
