AbstrakBelakangan ini hampir seluruh universitas yang ada di indonesia memiliki sistem informasi alumninya sendiri-sendiri. Sistem informasi alumni mampu memberikan informasi tentang kondisi alumninya setelah menyelesaikan masa perkuliahannya. Alumni merupakan aktor yang berperan penting dalam pendidikan. Saat ini jurusan Informatika Fakultas Teknik Universitas Muhammadiyah Malang telah memiliki website alumni. Permasalahannya belum adanya sistem yang memberikan alumni rekomendasi grup pada sistem, sehingga para alumni mampu saling bertukar informasi didalamnya. Dengan adanya data alumni dan juga di dukung dengan adanya tracer study, dapat di bentuk suatu rekomendasi grup dari data tracer study. K-medoid adalah metode pengelompokan data ke  dalam  sejumlah cluster  tanpa  adanya  struktur  hirarki antara satu dengan yang lainnya. Algoritma k-medoid memiliki nilai coefficient yang lebih tinggi di bandingkan dengan k-means dalam penelitian ini. Yang mana k-medoid mendapatkan nilai rata-rata Silhouette Score 0.7325888099 dalam pengujian dengan jumlah cluster 5 dan perulangan sebanyak 10 kali. Jika dibandingkan dengan k-means yang hanya memiliki nilai rata-rata Silhouette Score 0.6872873866.AbstractLately, Almost all universities in Indonesia have their own alumni information systems. The alumni information system is able to provide information about the condition of its alumni after collage graduation. Alumni are actors who play important role in education. Currently, the Department of Informatics, Faculty of Engineering, University of Muhammadiyah Malang has an alumni website.  The problem is the absence of system that gives alumni group recommendation on the system, so that alumni are able to exchange information in this website. With the alumni data and also supported by the existence of a tracer study, it can be formed as group recommendation from the data tracer study. Clustering is one of tools in data mining that aims to group object into clusters. K-medoid is a method of grouping data into a number of clusters without hierarchical structure from one another. The k-medoid algorithm has higher coefficient value compared to k-means in this study. This K-medoid gets an average value of Silhouette Score 0.7325888099 in testing with the number of clusters 5 and repetitions 10 times. When compared with k-means which only has an average value of Silhouette Score 0.6872873866.

Let be a category with finite products and a final object and let X be any group object in . The set of -morphisms, (X, X) is, in a natural way, a near-ring which we call the endomorphism near-ring of X in Such nearrings have previously been studied in the case where is the category of pointed sets and mappings, (6). Generally speaking, if Γ is an additive group and S is a semigroup of endomorphisms of Γ then a near-ring can be generated naturally by taking all zero preserving mappings of Γ into itself which commute with S (see 1). This type of near-ring is again an endomorphism near-ring, only the category is the category of S-acts and S-morphisms (see (4) for definition of S-act, etc.).

Abstract Although social representations theory often assumes that communication is a condition for the existence of social representations, research rarely assesses related properties. The study aims at characterizing the perception of ingroup communication relative to topics that are potential social representation objects for a sample of Brazilian undergraduates. The participants completed single-item Likert scales assessing twelve social objects in three communication dimensions: perception of frequency of ingroup communication, perceived importance of ingroup opinion and estimated agreement with ingroup opinion. One-sample t-tests and repeated measures ANOVAs were carried out to compare the score of each topic with the dimension means and among themselves. The results showed that objects such as university course and friendship had high scores in all three dimensions and are suitable objects for basic research when communication assumptions are considered. The discussion addresses the need for preliminary characterization to assess the group-object relationship in social representations research.

The research into the ratio of objective and subjective indicators of the volitional qualities of an individual conducted by the Department of General and Social Psychology of the UrFU discovered some limitations of the corresponding approaches to such multidimensional objects as volition. The research into individual semanticfields of the concept of ‘volition’ will make up for the existing methodological gap in that area. The research was conducted in 2017. The sample consisted of 77 students of the Department of Psychology. The semantic differential method in the modification by I.L. Solomin was used as a basis. The list of objects has been changed and expanded according to the tasks of the research. The second method of research is the associative experiment. The results were processed by using the methods of cluster analysis, factor analysis and content analysis. An analysis of individual cluster trees discovered a rather large variability of the semantic relationships between the objects under study. Several sub-groups of respondents were identified according to the individual characteristics of the semantic fields in relation to the object ‘volition’, the sub-group ‘success of activities’, the sub-group ‘personality qualities’, the subgroup ‘negative objects’ and the sub-group ‘object is not defined’. Most students consider volition either as an applied tool of educational or professional activities, or as a self-sufficient personal mechanism. With the help of factor analysis, the features of the affective attitude toward the object ‘volition’ in respect to the sample as a whole are revealed. The associative experiment made it possible to identify the key topic markers that characterize the volition of respondents of different semantic sub-groups. For the sub-group ‘success of activities’, it is ‘power’; it is ‘time’ for the sub-group ‘personality qualities’, in particular, ‘responsibility’; it is ‘firmness’ for the sub-group ‘negative objects’. The psychosemantics approach in studying volition allows us to identify topics that clarify the semantic nuances of the concept of ‘volition’ in the minds of the subjects. The method of the semantic differential and the method of associative experiment are mutually complementary with respect to research into the semantic sphere of a personality. The results obtained provide a necessary part of a comprehensive study of volition and the volitional qualities of aperson. Keywords: volition, volitional qualities, responsibility, students, psychosemantic approach, semantic differential, semantic field, associative experiment, semantic structures of consciousness, representations, individuality, cluster trees, topic markers

The collaboration script is defined as a formal way of describing the flow of activities within a collaborative learning session. Using collaboration script would encourage the production of effective and productive interactions between learners. Nevertheless, developing such script is not a trivial task. Standardization has played a major role in the expansion of instructional designs, but at the same time it limited down the flexibility of describing collaboration sessions that have complex structures. Representing a collaboration script in XML-tags format works well when scripting simple scenarios, but to describe extended scenarios it would make this scripting style very challenging and complicated. This approach causes users to avoid designing heavy weight scenarios and limits down their creativity. Relying on tools to implicitly generate such script would also limit down designers’ creativity since designers can only choose from a limited set of tools and design components. In this research, we have defined the bases of a new collaboration scripting language, CoScript, that is able to describe collaboration learning sessions in a simple, flexible, and formal way. This scripting language has been derived based on a theoretical framework that was proposed in an earlier research. The proposed scripting language notation is close to the notation of traditional software scripting languages. This makes it easier to be learnt by instructors with basic programming skills. It has the ability to describe design’s structure elements, such as sequencing, conditions, repetition, activities, activity’s input /output, group formation, etc. ColScript is basically composed of a limited set of objects and commands. The first part contains six objects (role object, group object, feedback object, collaboration tools object, time/date object and resources object), where the second part contains five essential structuring commands (input, output, loop, doactivity, groupformation).

The main purpose of this study is to explore the epistemological problems underlying pre-service chemistry teachers’ aims in using practical work, i.e., individual or small group object manipulation or observation, in school science. Twenty-two pre-service chemistry teachers participated in this study. Qualitative data collection tools included participants’ reflections about some practical work cases; participants’ practical work plans; responses given to open-ended questions about practical work, scientific inquiry, the epistemology of science, and science teaching approaches such as discovery and inquiry based learning; and follow-up interviews. Through the qualitative analysis of the data, participants’ aims were grouped under three main themes, which included six categories: providing learning by discovery to students, serving to verify scientific theory, making scientific theories concrete, developing students’ scientific process skills, providing learning about the nature of science, and creating curiosity and motivation towards science. Arguments related to any epistemological problems underlying some of these aims are presented in the Results and discussion section. Based on the results, conclusions were made about the sources of these epistemological problems, why the epistemology of science should be considered explicitly when teaching the science teaching approaches and using the practical work, and why “teaching nature of science implicitly” failed.
