Insufficient Knowledge

Problem orientation as a part of mathematics education is required by mathematicians already for a long time and since the beginning of ProMath meetings the situation in school has been improved a little bit, but it is still practiced not sufficiently. Resistors among other enhancements are special beliefs about mathematics education and insufficient knowledge about problem orientation. This is the reason I offered again a seminar for teacher students about problem orientation in mathematics education in summer 2016. In the following first I will briefly discuss different type of problems and then as the main part report and discuss results of a written survey on knowledge to problem orientation at the beginning of the seminar as well as personal comments the students have made during the seminar sessions and in protocols on the seminar sessions.

The article discusses a unique monument of rock-art on the territory of Xinjiang – namely the petroglyphs of Kangjiashimenzi (Hutubi County). The person who began scientific investigation of this site in 1987 was Professor Wang Binghua. From that time, the issues of Hutubi petroglyphs became among the most popular topics in Chinese archaeological literature but only in a few publications in other countries and only one – in Russia. This article aims to fill this gap. The Kangjiashimenzi rock-art panel comprises 292 images of different size composed as a whole ensemble depicted using a counter-relief technique, with some grinding after. The images were given in quite stylized (dancing) poses. The male figures are often presented with an erect phallus. The picture also includes several coitus scenes. We supposed this ensemble in general served as a pictorial reflection of ancient mystery-plays connected with genus or tribal worships and with sacred wedding rituals. The main part of the petroglyphs dates to the Middle Bronze Age (circa first half of II millennium BC). On the territory of Xinjiang this period was presented by Xiaohe Culture. Within these rock-art engravings, two groups of petroglyphs, most likely, with later dates can be distinguished though they were very precisely incorporated into the ensemble. Images of ‘tigers’ one could connect with activity of nomad tribes of Saka (circa first half of I millennium BC), and antithetical figures of two horses – with some other nomad tribe of Yuezhi (circa II century BC). In any case, the monument with rock engravings has been created and used over quite a long time. It is very probable that Kangjiashimenzi was a functioning sanctuary, at least for the whole region.

Mathematics in context (MiC) is an integrated program that uses Realistic Mathematics Education(RME) approach to teaching and learning of mathematics. It emphasizes learning mathematics from realistic situations, students’ invention or construction of solution procedure and interaction with other students or the teacher. Students should be encouraged to make sense out of real problems and the mathematics instruction should be designed accordingly. This article deals with the underlying principles of RME and highlights the features of MiC in Nepalese Mathematics Education.

Aim. To make a review of Hevea and Manihot, two related plant genera that have been used by humans for a long time, to analyze their biological features, to give information on their use, to present the most interesting materials associated with them. Main part. A review of Hevea and Manihot, useful plants in the tropics and subtropics, is carried out. Their characteristics are given, biological features are considered, and data on the places of origin, on the regions where they are cultivated are considered. Information on their use by people is presented: Hevea as a rubber-bearing, cassava as a food product. Special attention is paid to the cytogenetic features of Hevea and Manihot, information about the ancient polyploid origin of these plants. Conclusion. From ancient to the present time, mankind has been using in everyday life many valuable species of subtropical and tropical plants, including Hevea and Manihot, which are an integral part of ethnocultural traditions.

Based on Dewey’s theory of art, aesthetics, and experiences and photographer Barnbaums’ writing about expanded perception through photography, we conducted a one-day experimental mathematics education unit. Using photography in outdoor conditions had a positive impact on teacher students’ perception of the use of photography for teaching mathematics. To study the changes in students’ visual attention deeper, we used gaze-tracking to analyse one student’s visual attention when walking outdoors after the activity. The gaze data indicated that more visual attention was given to objects he had photographed or discussed during the group activity in comparison to other objects.

Clear Idea

AbstractThe starting point of this paper is the question how the graphematic sentence, i. e. the written sentence, can be defined. The answer seems to be clear: a graphematic sentence begins with a sentence-initial capital letter and is concluded by a sentence-final punctuation mark such as the full stop or the question mark. However, this definition is problematic since it requires an underlying (syntactic) definition of the sentence in general. Yet within linguistics there is no commonly accepted definition of the sentence (cf. section 1). Language users (linguists among them), however, seem to have a clear idea of what a sentence is. In the paper I argue that this seemingly contradictory situation could be explained on the following two assumptions. (a) The widespread clear intuition about the existence of a linguistic category called ‘sentence’ mainly derives from the influence of the written language on concepts of language in general. (b) Yet this influence has never really been taken into consideration for sentence definitions within modern linguistics due to the fact that written language has for long time been neglected as an object of linguistic research (cf. section 2). The main part of the paper (section 3) is concerned with a definition of the graphematic sentence without recourse to syntactic structures. It reveals that in German the graphematic sentence is a clearly recognizable unit within the writing system and therefore seems to be predestined for being the conceptional model for the idea of what a sentence is. Based on the punctuation theory of Bredel (2008, 2011) I argue that punctuation marks do not

Based Instruction

Developing students' abilities in using and selecting appropriate representations and making transformations between representations is an important issue in mathematics education. Among the mathematical concepts, fractions have always reported as a challenging issue for students in the middle schools for a long time. In this sense, researchers have suggested the use of different representations in learning and teaching of fractions in order to enhance students' conceptual understandings of fractions. Based on this suggestion, we provide some activities for engaging middle school students with multiple representations of fractions by focusing on addition operation. These activities are focused on the need to identify appropriate instructional strategies to enhance students' communication and critical thinking, thus improving their academic performance in mathematics.

Many—probably most—researchers in mathematics education have spent considerable time as teacher educators, working with people who soon will be or currently are reaching mathematics. Perhaps surprisingly, then, these researchers have not viewed teacher education as a potential research site. Immersed in the activities of teacher education, they have not stepped outside the arena of their daily work to view it with the researcher's eye. They resemble the fish in the saying, who, if they were scientists, would be a long time discovering water.
