Can It Screen? Exploring the Usability of a Data-driven Lean Canvas Framework for Startup Selection in Accelerators
Authors: Jowhar Ahmad
Published: March 2024

The emergence of startups across various industries has resulted in an influx of new ventures seeking guidance from entrepreneurial programs to assist in their development, including startup accelerators. However, given the human capital and time constraints faced by accelerators, issues arise on selecting the most optimal startups. This thesis proposes a framework that would leverage startup’s application into an accelerator to create insightful features, through machine learningtechniques. Furthermore, the leancanvasframeworkwould be utilized to mapthe features to its respective dimensions and identify the impact each dimension has on the startup selection process. I extensively studied the effectiveness of this framework by analyzing startup’s application to a US-based accelerator. The most important features were a startup’s competitive advantage and industry similarity with accelerator programs. The proposed pipeline introduces a unique framework to assist in the startup selection process and contributes to the growth within the entrepreneurial ecosystem.
Zebra finch song parameters are affected by the breeding status of the male and the ambient temperature conditions
Authors: Maëlle Lefeuvre , Rutkowska Joanna
Published: March 2024

Bird song is a crucial feature for mate choice and reproduction. Song is known to communicate information related to the quality of the mate, through song complexity, structure or finer changes in syllable characteristics. It has been shown in zebra finches that those characteristics can be affected by various factors including motivation, hormone levels or extreme temperature. However, although the literature on zebra finch song is substantial, some factors have been neglected. In this paper, we recorded male zebra finches in two breeding contexts (before and after pairing) and in two ambient temperature conditions (stable and variable) to see how those factors could influence song production. We found strong differences between the two breeding contexts: compared to their song before pairing, males that were paired had lower song rate, syllable consistency, frequency and entropy, while surprisingly the amplitude of their syllables increased. Temperature variability had an impact on the extent of these differences, but did not directly affect the song parameters that we measured. Our results describe for the first time how breeding status and temperature variability can affect zebra finch song, and give some new insights into the subtleties of the acoustic communication of this model species.

Published: March 2024

Despite playing a central role in peoples’ daily life, the average Kenyan secondary school students’ mathematics score in national examinations has consistently averaged below 40%. The contribution of teachers’ lesson preparations and subsequent delivery leading to this poor result has not been investigated sufficiently in Kenyan secondary schools. This is especially so for topics deemed to be difficult. The present study investigated the effect of teacher preparations when teaching the topic “Vectors” to form three secondary school students. The instructional plans impact on achievement as well as on skills performance in Mathematics formed the objectives of the study. The Solomon- four experimental design was adopted. Professionally drawn Instructional Plans provided the treatment. Students’ achievement was determined using a Mathematics Achievement Test, MAT. The study determined that the use of the instructional plans improved students’ achievement and skill performance compared to the control group. Consequently use of instructional plans when teaching mathematics was recommended for improved students’ achievement. Emphasis on students’ stepwise skill performance rather than insistence on acquisition of correct answers during problem solution in mathematics was recommended.

ON USAGE OF INDUCTIVE APPROACH IN MATHEMATICAL TEXTBOOKS AT SECONDARY SCHOOL
Authors: Břehovský Jiří , Emanovský Petr
Published: March 2024

Quality of mathematical education is very actual didactic issue at present. One possibility how to increase it is a use of unconvencional experimentally inductive approach. The appropriate textbook then can be a useful helper for teacher who intends to apply this approach. There are given an analysis of the usage of inductive and deductive approach in mathematical textbooks here. The research was focused on the content of mathematics textbooks for secondary school, on their interpretative and exercise text components, respectively. The main interest was to explore the representation of inductive and deductive methods in interpretation of the mathematics textbooks and to measure the content of the exercises whose student's solution requires the use of heuristic approaches. The results of the analysis show that each author prefers a different approach to interpretation which is used in the writing of textbooks. Interpretative means most contained in all the textbooks are a direct interpretation with the motivation (34.4%), a direct interpretation without motivation (31%) and an indirect interpretation with the motivation (24.5%). Inductive and deductive interpretative means are only rarely represented in all the textbooks. The highest rate was registred in the case of task using interpretation with the motivation (7%).

THE CHARACTERISTIC FREQUENCY BANDS ANALYSIS OF BRAIN WAVE DURING LEARNING
Authors: Kao Fu-Chien , Li Wei-De , Hsien Han-Chieh , Wang Chih-Hung
Published: March 2024

The traditional E-learning often offers the online examination to assess the learning effect of a student after completion of the online learning. Basically, this traditional learning assessment mechanism is a passive and negative assessment mechanism, which cannot provide an real-time learning warning mechanism for teachers or students to find out problems as early as possible (including such learning conditions as “absence of mind” resulting from poor learning stage or physical or psychological factor), and the post-assessment mechanism also cannot assess the learning effectiveness provided by the online learning system. This research paper attempts to acquire the electroencephalogram to analyze the characteristic frequency band of the brainwave related to learning and formulate the learning energy index (LEI) for the learner at the time when the learner is reasoning logically via the brain-wave detector based on the cognitive neuroscience. With the established LEI, the physical and psychological conditions of an online leaner can be provided instantly for teachers for assessment. Given that the learning system is integrated into the brainwave analytic sensing component, the system not only can provide learners an instant learning warming mechanism, but also help teachers and learning partners to further understand the causes of learning disorder of learners, and can also provide relevant learning members with timely care and encouragement. This research will discuss and analyze such subjects as the electroencephalogram difference between the traditional print textbooks and the multi-medium textbooks, whether the development of exercise habit will be help to learning by means of a view of cognitive neuroscience except for the analysis of characteristic frequency band of the brainwave represented at the time when learners adopt diverse learning methods.

Authors: Kukkonen Jari , Kärkkäinen Sirpa , Valtonen Teemu , Keinonen Tuula
Published: March 2024

This study aims to clarify primary school teacher students’ experiences about the use of blogs in the context of a science course which includes collaborative inquiry-based approaches and a field trip. Teacher students were asked to design and conduct a small inquiry and report the phases of the process in a blog and then write their ideas about inquiry-based teaching and learning in it. The inquiry process was loosely scaffolded by linking the blogs together. The students were also asked to fill in a questionnaire of technological pedagogical content knowledge (TPACK), in order to acquire insight into their views on the scaffolding needed for their own inquiry process, as well as the role of scaffolding in the inquiry method in primary school. The findings showed that after discussing them with each other, teacher students were able to formulate personally meaningful problems for their investigation. Teacher students investigated multidisciplinary elements and learned about different phases of the inquiry and the blogs enabled them to follow the process of others. Teacher students’ information retrieval and processing skills developed through out the inquiry and aided them in other teacher education courses, also giving them a firm foundation and confidence in accessing and applying information as life-long learners.

CHALLENGES OF THE EDUCATION FOR SUSTAINABLE DEVELOPMENT WITH PARTICULAR FOCUS ON THE SUB-SAHARAN AFRICA CONTEXT
Authors: Lamanauskas Vincentas
Published: March 2024

The education for sustainable development is one of the major challenges of our époque, because it is the key to make sustainable development possible by fostering informed, active and convinced participation from the public. It is also a novel type of challenge, because it needs to reach the public at large, and not only learners within the formal instruction systems, and it needs to promote responses in terms of sustainable behaviour patterns. Therefore, it needs to expand beyond science education and to incorporate and utilise additional types of information in order to design the best communication options for each type of audience. On the other hand, it requires a certain level of science literacy to offer adequate motivations on proposing sustainable behaviour patterns; therefore, it may also need to address the issue of science literacy when necessary, above all when targeting the general public.
After an introductory overview of the general features of these challenges, the paper focuses on the Sub Saharan Africa context and attempts to outline options for the integration of the new messages inherent in the sustainable development concept with relevant aspects of the local realities. Specific attention is given to the challenges common to science education and to sustainable development education (mostly stemming from historical reasons); to the challenges of education aimed at fostering sustainable patterns; to possible routes for the youths’ active participation in the dissemination of information and in the design of viable sustainable options; and to the importance of connections with traditional systems of knowledge and values.
Key words: education for sustainable development, formal and informal education, indigenous knowledge systems, language of instruction.

This research was conducted to synthesize MgFe2O4 using the coprecipitation method by varying the concentration of NaOH. In this study, MgCl26H2O, iron sand, 37% HCl and variations of NaOH (5 M and 10 M) were mixed at 90 ℃ for 60 minutes, then washed using distilled water and ethanol until pH = 7, and calcined at 750 ℃. The test results using X-Ray Diffraction (XRD) showed that the diffraction pattern of phase formation identified was MgFe2O4 with hkl values (220), (311), (400), (422), (511), and (440). The resulting crystal size decreased with the addition of NaOH concentration. The test results using a Vibrating Sample Magnetometer (VSM) show that the magnetization value decreases when the crystal size decreases.

Critical thinking is necessary to search for new ideas and discoveries to address the complexities of life in the 21st century. One effort to meet this need is the implementation of a team-based project-based learning model. This model aims to influence students' critical thinking skills. However, the implementation of this learning approach is not yet supported by well-developed instructional materials. The existing modules still have some limitations as they were created at the beginning of the program implementation, and certain field conditions require adjustments and improvements to align with the encountered problem contexts. This research follows the Research and Development approach, using the development steps proposed by Borg and Gall, which include: 1) Needs analysis; 2) Planning instructional material development; 3) Design validation; 4) Small group product testing; 5) Product revision; and 6) Large group product testing. The data sources for this study consist of: (1) Expert assessment data, (2) Small group testing results, and (3) Large group testing results. The research was conducted in the Elementary School Teacher Education Program at Tadulako University, with the subjects being students from the 2019/2020 cohort. The results of the study indicate that the Team-Based Project-based Learning Module for Elementary School Number Operations is considered valid and practical based on the validation results from subject matter experts, media experts, initial field testing, and main field testing. Therefore, the module is deemed suitable for use.
