Development Of Pisa-Oriented Problem Based Learning Media To Improve Mathematic Problem Solving Abilities Of VII Grade Junior High School Students

The learning media used in schools, such as worksheet, are not optimal yet to help students build their understanding. For this reason, it is necessary to develop learning media so that they can provide opportunities for students to find their own concepts and can be remembered for a long time. This study developed a PISA-oriented problem-based learning (PBL) media. This research was a development research (R&D). This research used the Plomp model which consisted of three stages, namely the preliminary research stage, the prototyping phase, and the assessment phase. At the preliminary research stage, needs analysis, curriculum analysis, concept analysis, student analysis was applied. In the prototype-making phase, a prototype development was applied which had been validated and tested. Whereas in the assessment phase, the developed prototype was tested and assessed for practicality and effectiveness, which was assessed by observation, questionnaires, and student learning outcomes. The validation of learning tools is viewed from the content validity and construct validity. The average value of the PISA-oriented PBL-based student worksheet validation was 3.57 with a very valid category. Based on the student response questionnaire, it was found that the learning media was practical with a percentage of 86.83%. Problem solving problems were given to test the effectiveness of the learning media being developed, and the results were these devices are effective for use. After all stages of development, it was concluded that the media being developed were valid, practical, and effective.

Représentations des Elèves et Elaboration d’une Démarche Expérimentale

[Representations of Students and Development of an Experimental Approach]ABSTRACTThis work presents the representations of the students and the development of an experimental approach by the teachers of Life and Earth Sciences (SVT) at the college. The results we obtained show that this teaching practice is widely used by them to solve a problem or test a hypothesis. However, the teachers summarize the experimental approach essentially to experimentation and its links with student representations, and its use as a tool to facilitate learning. We were also interested in the difficulties they oppose in this process Keywords: Scientific approach, SVT teaching, Science experimentation, Representations.

Application De La Démarche Expérimentale Dans L’apprentissage

[Application Of The Experimental Approach In Learning]ABSTRACTAchieving the objectives outlined in an experimental process requires the establishment of an induction phase, which consists of an open space offering the opportunity for learners to state their hypotheses while collectively choosing one and a few variables, a deductive procedure comes second. However, adopting such an approach faces difficulties for learners to formulate hypotheses consistent with theoretical data. Lack of critical thinking in learners as well as their inability to interpret experimental results is also a problem in this teaching practice. It is important to note that the experimental method should not be limited to manipulation and analysis of the results by the learners.

Philosophical And Methodological Aspects Of The Scientific Picture Of The World And The Humanization Of Science

In the modern intellectual question analysis of the humanitarian fields of scientific knowledge is indicated as an important philosophical problem. The fundamental intentions of the cultural development of the 21st century intersect at this point: on the one hand, there is an awareness of the loss of spirituality, and on the other, the indication of science as the highest human value. Science, entering into the mysteries of space, living matter and the human body, creates rise to acute social, ideological, methodological and humanistic problems concerning the individual and social aspects of man. The large amounts of scientific knowledge development should be combined with humanistic ideals, otherwise it is sure to give rise to further discord to the human condition and the world of culture. Next natural question arises in the problem of humanizing science context: "What should be the peak of scientific knowledge in order to avoid further mismatch between man and nature, society, science and humanitarian ideals?" As a result, the task arose to supplement the analysis of scientific aspects of cognition with an analysis of its synergetic, existential, axiological components. It is necessary to consider cognition not only as discovering the objective truth apart from man or from mankind, and also as part of the human-species, containing valuables that act to determine the human genuineness. With this in view, we will consider how the ideal of science is changing, leading from principle ontology when the most significant value for the cognizing subject is the world in itself, to taking into account the subjective conditions under which principles of new knowledge are gained. The evolution of the paradigm of science and the scientific picture of the world is shown. This evolution goes through three stages: classical, non-classical and post-non-classical.

The Carbon Footprint Of Smallholder Dairy Farming In Sub-Saharan Africa: A Review

Agriculture sector is one of major sources of income and livelihood to many populations of Sub-Saharan Africa (SSA). Over the past years animal production has been playing a vital role not only in generating revenues to farmers but also as a source of high qualitative proteins and essential micronutrients (i.e iron, zinc and vitamins) and boosting the agricultural productivity due to its importance in farmyards organic fertilization (i.e manure). Livestock production and Milk market in SSA are dominated by smallholder dairy farming (SDF) which employ nearly 70% of all livestock farmers. Despite its positive impact on people and SSA countries’ economy, SDF has been the major fastest growing agricultural contributors of GHG emissions such as CH4, N2O and CO2 (i.e 9t CO2e per tonne of milk; the highest in the world compared to other regions) thus accelerating global warming effect.Although several articles have investigated the impacts of livestock production on climate change, to the best of our knowledge the existing literature doesn’t contain any studies that provide insight review of smallholder dairy farming’s carbon footprint (CF) in SSA. This review paper is therefore aimed at critical analysis of current knowledge in terms of CF of smallholder dairy farming in SSA and effective mitigation strategies (dietary, manure and animal management) recently proposed to reduce CH4 and N2O emissions from ruminants. SSA was selected because of rapid rise of SDF in the region therefore it is expected to rapidly increase its GHG emissions in future if no sustainable measures are taken.The critical analysis, what is known and gaps in SDF from this review will help to inform the farmers, researchers, decision and policy makers interested in GHG emissions thus to provide the next direction in research and improvement of the sector for sustainability. Capacity building for raising awareness among farmers was identified as paramount to better understand the issue and the options to mitigate emissions on-farm. As longer as adaptation and mitigation strategies become paramount on national and regional agenda, SDF will make significant contribution to economies, improved livelihood and become sustainable livestock production systems in SSA at large.

Communication Practices of Single Mothers in Carrying Out Their Dual Roles

The research aims to analyze the communication practices of single mothers in carrying out their dual roles. This research approach is a critical qualitative case study method. The research data were collected through in-depth interviews with a number of informants and participatory observation. The research results show that there are five interaction arenas of single mothers in carrying out their dual roles, i.e. with their household, fellow single mothers, women, men, and with the environment / community. Communication practices that they are carrying out are interpersonal, avoiding conflict when interacting with men, and messages that tend to be emphatic when interacting with the community. Therefore, communicating their dual roles is a necessity because single mothers are frequently confused when they have to choose between housewife and modest public / productive role or they try to balance both roles if they have a larger productive role.
