Scientific Skill Development In Kindergarten Education Post-Covid-19

The decisive learning skill for the scientific knowledge acquisition developed by artificial intelligence

Several researchers in the field of education have taken an interest in the development of scientific skills. Their objective is to enable learners to have an attitude of reflection and behavior in the face of the different pedagogical situations that may arise. We are also interested in these scientific skills, namely C1: Appropriate, C2: Analyze and reason, C3: Achieve, C4: Validate and C5: Communicate, we have characterized them by capacities whose objective is to evaluate them with interesting precision. We are interested in all these scientific skills but with significant weightings in order to realize a balanced, complete and effective overall assessment of scientific learning. In this work, we will also discover the most important scientific skill for the construction of Knowledge in a given scientific session, using artificial intelligence based on the decision tree by implementing a program in Python. Therefore, taking into consideration the one that leads to the birth of ideas and that allows to converge towards the objective, the teacher gives more importance to this skill and develops it by proposing different specific pedagogical situations. This learning approach allows the teacher to make the right decisions at the right time and it allows equity between the learners to acquire the different scientific skills according to their learning ability. Therefore it allows the learner an intrinsic motivation for the acquisition of scientific knowledge.

Effectiveness of Outdoor Physics Activities

This paper presents the utilization of outdoor physics activities in the teaching of selected topics in light and optics in order to promote effective transfer of learning in physics and interacting with the environment which is one of the main subjects of the study. The study also looked into the effect of cooperative learning, active learning, use of higher order thinking skills (HOTS), relevance of learning experiences and development of social skills in physics among fourth year high school students in a secondary school in Bacacay, Albay. The researcher developed outdoor physics activities as an instructional intervention and used a single group pretest- posttest design. Qualitative and quantitative techniques were used in the study. The instruments used in data gathering were the teacher- made questionnaire for the features of the outdoor physics activities in optics and results of the pretest- posttest for conceptual understanding and the guide questions for the journal entries of the students. Validation of data was done through triangulation of students’ journal entries, self-rating checklist and experts’ observation. Positive result shows in the conceptual understanding, development of scientific skills, enhancement on the attitude and values and improvement on the social skillsof the students. Further, it is recommended that additional outdoor physics activities be developed for the enrichment of the students’ conceptual understanding as they see their relevance to real life experiences.

Learning outcomes of the educational board game “Taphonomy: Dead and Fossilized,” evaluated with high school learners in a summertime program

Although many have suggested the use of games to motivate active learning, studies that evaluate the learning outcomes of games with high school students are scarce. Here, we present the evaluation of the board game “Taphonomy: Dead and Fossilized” as an active learning tool to teach fossilization and Earth systems thinking with rising 12th grade learners in GeoFORCE Texas, a summertime outreach program of the Jackson School of Geosciences, The University of Texas at Austin. The educational activity was evaluated with two groups (n1 = 22, n2 = 27). During the activity, an observation protocol was implemented; prompts to evaluate learners’ behaviors and instructor behaviors were included in a form that a trained observer filled out while the learners played the game. Learning outcomes were assessed with a 2-page paper survey immediately following gameplay; survey questions are aligned with the Next Generation Science Standards. “Strategizing” was the most common learner behavior observed during the activity and the majority of behaviors can be considered “active learning”. The results from the survey show that after playing the game learners were able to apply paleontological knowledge to tasks that involved establishing cause-effect relationships and Earth systems thinking. Our results provide evidence that board games (as educational strategies) are effective active learning tools that foster student development of scientific skills. Cooperative learning was observed, which we suggest is a key benefit for diverse classrooms. Findings were used to guide the refinement of the high school-level version of “Taphonomy: Dead and Fossilized”, as well as a scaffolded teaching module with formative and summative questions for use in a classroom setting.

Practical Work by Laboratory Stations: An Innovation in Experimental Work

Experimental work is essential for the development of scientific skills and student motivation. However, students are not always involved in the experimental work, and the development of scientific skills is compromised. In this study, the model of experimental teaching of Chemistry and Physics by laboratory stations is presented and its contribution to the promotion of self-efficacy and self-regulation is discussed. This model had underlying active learning, neuroeducation and was developed using a collaborative Peer Instruction approach. The regular use of laboratory stations during two years, in two classes of basic education, allowed not only counteracting the distance between the students and Physics and Chemistry but also improving the students' engagement in classrooms. The purposes of this implementation were to develop students' Chemistry and Physics knowledge, to engage students in the classroom activities, and develop scientific skills (handling equipment, making and describing observations, recording data, gave meaning to measurements, obtaining experimental results, discuss and analyse results, planning experiments to verify hypotheses). The promotion of collaborative work habits among students, critical thinking and the debate between peers as strategies to achieve significant learning were also other aims of this methodology.

Developing technological pedagogical science knowledge through educational computational chemistry: a case study of pre-service chemistry teachers’ perceptions

The purpose of this descriptive case study was to develop pre-service chemistry teachers’ Technological Pedagogical Science Knowledge (TPASK) through novel computational chemistry modules. The study consisted of two phases starting with designing a computational chemistry based learning environment followed by a case study where students’ perceptions towards educational computational chemistry were explored. First, we designed an authentic research-based chemistry learning module that supported problem-based learning through the utilisation of computational chemistry methods suitable for pre-service chemistry education. The objective of the learning module was to promote learning of specific chemistry knowledge and development of scientific skills. Systematic design decisions were made through the TPASK framework. The learning module was designed for a third-year physical chemistry course taken by pre-service chemistry teachers in Chile. After the design phase, the learning module was implemented in a course, and students’ perceptions were gathered using semi-structured group interviews. The sample consisted of 22 pre-service chemistry teachers. Data were analysed through qualitative content analysis using the same TPASK framework employed in the learning module design. Based on our findings, pre-service chemistry teachers first acquired Technological Scientific Knowledge (TSK) and then developed some elements of their TPASK. Besides, they highly appreciated the combination of student-centred problem-based learning and the use of computational chemistry tools. Students felt the educational computational learning environment supported their own knowledge acquisition and expressed an interest in applying similar learning environments in their future teaching careers. This case study demonstrates that learning through authentic real-world problems using educational computational methods offers great potential in supporting pre-service teachers’ instruction in the science of chemistry and pedagogy. For further research in the TPASK framework, we propose there would be significant benefit from developing new learning environments of this nature and evaluating their utility in pre-service and in-service chemistry teacher's education.

Increased Scaffolding and Inquiry in an Introductory Biology Lab Enhance Experimental Design Skills and Sense of Scientific Ability.

We present a model for the process of redesigning the laboratory curriculum in Introductory Organismal Biology to increase opportunities for meaningful inquiry and increase student recognition of their scientific skill development. We created scaffolded modules and assignments to allow students to build and practice key skills in experimental design, data analysis, and scientific writing. Using the Tool for Interrelated Experimental Design, we showed significantly higher gains in experimental design scores in the redesigned course and a more consistent pattern of gains across a range of initial student scores compared with the original format. Students who completed the redesigned course rated themselves significantly higher in experimental design, data collection, and data analysis skills compared with students in the original format. Scores on the Laboratory Course Activity Survey were high for both formats and did not significantly differ. However, on written course evaluations, students in the redesigned course were more likely to report that they engaged in “real science” and their “own experiments.” They also had increased recognition of their specific analytical and writing skill development. Our results demonstrate that intentional, scaffolded instruction using inquiry modules can increase experimental design skills and sense of scientific ability in an introductory biology course.

Effects of Modeling Instruction Professional Development on Biology Teachers’ Scientific Reasoning Skills

International assessments have revealed that students in numerous nations lack scientific reasoning skills. Science teachers who support students’ scientific skill development through the use of authentic practices provide students with tools needed for success in future science courses. Teachers training focused on pedagogy that supports student scientific reasoning development is particularly important as some studies have also suggested that pre-service teachers have a tendency to display a lack of scientific reasoning skills. Additionally, few studies exist that assess teachers’ scientific reasoning skills, including the effectiveness of professional development to strengthen teacher scientific reasoning abilities over time. To help fill this gap, this study examines the effects of a Modeling Instruction in a biology workshop on teachers’ scientific reasoning skills. In addition to teacher interviews, focus groups, and writing samples, data from Lawson’s Classroom Test of Scientific Reasoning (LCTSR) were collected from teachers before and after the workshop. The results suggest that the three-week Modeling Instruction in the biology workshop contributed to gains in in-service teachers’ scientific reasoning, and thus provides evidence that the teachers in this study are more prepared to help develop similar skills with their own students as they engage in the Modeling Instruction curriculum.

Argumentação de estudantes da educação básica sobre dilemas sócio-científicos no projeto ENGAGE

This study was carried out within the framework of the European ENGAGE project which proposes the development of scientific skills in the context of Responsible Research and Innovation (RRI). It has been questioned, how do students use evidence-based argumentation to justify opinions about socio-scientific dilemmas? It aimed at proposing alternative methodologies to teachers to improve students' performance in the study of science. The research was a partnership between the Open University (OU-UK) of England and the State University of Bahia (UNEB), held in a public school in the Municipality of Irece-Ba-Brazil, with students of basic education. All the elements of the argumentation were identified during the activities carried out by the students of the three groups analyzed. However, it was observed that they presented difficulties to elaborate a justification based on evidence, responding to the proposed dilemma and describing scientific thinking in a systematized form. The study also pointed out the need for continuity of research using technological elements that would support the student with the structuring of his ideas.

Agriscience Education Through Inquiry-Based Learning: Investigating Factors that Influence the Science Competence of Middle School Students

Inquiry-based teaching methods have been found to enhance students’ abilities to understand the process of scientific inquiry. The purpose of this study was to determine if middle school students taught through an inquiry-based teaching approach consisting of scientific skill development, scientific knowledge, and scientific reasoning were more likely to meet their respective science grade level expectation. Participants consisted of predominantly Hispanic sixth and eighth grade students enrolled in school enrichment programs through the MMSAEEC. Inquiry-based instruction was integrated within science classes using lessons in soil pH and water quality. Overall, sixth grade students scored highest on items related to science skill, while the eighth grade students scored highest on the science knowledge portion of the instrument. Regarding the sixth grade students, science reasoning and science skill were found to be significant predictors of grade level expectation, while science skill was significant for the eighth grade data. It is recommended that teachers incorporate inquiry-based learning strategies into their classrooms to encourage students to ask questions and refine their ability to think critically and solve problems. Further research is needed to clarify the role of science comprehension and the associated sub-dimensions with the ability to predict grade level expectation.

From inception to implementation: an Argentine case study of teachers enacting early years inquiry-based science

This study aimed to understand the process of implementing an early years inquiry-based science unit, focusing on the challenges teachers faced. A two-month professional development programme was implemented in two preschool classrooms. Two teachers with no inquiry-based science experience were provided with structured curriculum units and weekly pedagogical coach. Teachers observed coach-led model lessons (which were filmed and used during subsequent training) before implementing four 30-min lessons. Lessons and teacher interviews post-programme were filmed and their verbatim transcriptions analysed. Overall, teachers executed most basic elements from the units, providing students with opportunities to engage in scientific explorations. However, they struggled to use the activities for the collective construction of knowledge and development of scientific skills. Analysis of student–teacher dialogues shows that teachers rarely used student inputs to articulate prior knowledge with new concepts or to inform teaching, sometimes constructing misleading ideas about the nature of science as a result.

Mathematics and Nutritional Status: A Proposal for the Development of Research Skills

In the last two decades of the 20th century and the first of this, the academic community has been reflecting about girls and boys as scientists. Some authors propose thinking the activity scientific as an activity cognitive that looks like what the children and girls make in the world that surrounds them. Within this approach, the development of scientific skills can assimilate to certain specific thinking skills of research processes. This work has as objective the development of a didactical proposal in the area of mathematics for the development of skills cognitive, starting from processes of research on the nutritional status of the girls and the boys, driving concepts as Index of Mass Body and Carving for the Age. The work was carried out with sixth grade students of education basic of the educative institution Felix Henao Botero of the city of Medellin, in Colombia. The area of mathematics was the base for the development of this project that also sought that the student acquires the basic skills of the course in the mathematical thinkings required for the grade. The paper presents the theoretical basic approaches in that it is supported the project, the structure of the intervention made, as well as the results obtained in front of the skills that they can develop.
