In this paper we investigate the ways that a graphical and a textual Computer-based Programming Environment (CPE) support student inquiry in science during scientific modeling. We analyzed the conversations of 78 sixth-graders (39 students per CPE group) that took place during the construction of models, as well as, student-constructed models specifically looking for ways that CPEs support student scientific inquiry. Our findings showed that CPEs enable students to develop models of physical phenomena and operationally define physical entities and physical properties, which provides students with a commonly shared language for communicating and understanding each others' ideas in science. We also found that programs in CPEs produce a computer microworld that is a structured environment learners can use to explore and manipulate a rule-generated universe, subject to particular assumptions and constraints that serve as representations of aspects of the natural world. Microworlds can also provide learners with opportunities to manipulate realities in ways that learners cannot do with physical objects. Implications from this study suggest productive features for computer-based tools that can be embedded in web-based learning platforms for supporting students' inquiry and science learning.

We investigate how a teacher's personal reflection shapes her decision-making process in classroom management. Following open coding, we analyze the teachers' reflections seeking to identify her rationale in the decision-making process during the language arts lessons. Our findings indicated that her thinking was based on the student's behavior, the student's personality, the educational context, her own emotional perspective and condition, her pedagogical knowledge, and her reflective experience. We discuss the theoretical and methodological implications.

This is a case study describing the ways I engaged a group of 20 5-6,5-year-old children in an afternoon, distance, science education unit investigating snails. The study took place during the Covid-19 quarantine time in Spring 2020. The paper demonstrates the transferability of pedagogical ideas usually implemented in the face-to-face classroom. It also illustrates pedagogical ideas that were more productive to use during the online unit. Lastly, it describes the development of an online learning community that included children and parents.

Despite its proven added value, Modeling-based Learning (MbL) in science is not commonly incorporated into early grades. My purpose in this study was to provide detailed descriptions of the implementation of MbL with a group of 18 pre-K children, engaged in the study of solution of substances in water. The findings suggest that participants could successfully engage in authentic MbL activities, being able to develop a number of different models using prior knowledge and experiences, as well as a variety of features of both analogical and mechanistic reasoning. © 2020 International Society of the Learning Sciences (ISLS).

The purpose of this descriptive case study was to better understand the characteristics of Teacher Professional Learning Communities(TPLCs) of pre-service teachers(PsTs). Data were derived from 2 TPLCs in which 15 PsTs volunteered to participate, within the context of a pre-school Science Education course they were enrolled in. We analyzed transcripts of videotaped TPLC meetings following the thematic analysis approach. Our findings provide insights about how this group of PsTs utilized opportunities for professional growth.

This symposium addresses methodological issues in studying children's knowledge and learning processes. The class of methods discussed here looks at processes of learning in fine-grained detail, through which a theoretical framework evolves rather than is merely applied. This class of methodological orientations to studying learning processes diverges from more common ones in several important ways: 1) Attention to diverse features of the learning interaction; 2) conducting a moment-by-moment analysis, zooming in on the fine details of the studied processes; 3) rather than proving or applying a theory, the objective is to make theoretical innovations, or to develop a "humble theory." The challenge of using such techniques is that, by their nature, they do not follow a strongly delineated procedure, especially not the usual sort of coding. This symposium attempts to begin addressing the methodological issues by reflecting on several cases of data analysis.

Despite its proven added value, Modeling-based Learning(MbL) in science is not commonly incorporated into early grades science education. Following a growing body of research on using MbL in early grades, this multi-case study seeks to provide detailed descriptions of the implementation of MbL with 3 groups of pre-K children engaged in the study of three different phenomena, taught by 3 different teachers participating in a professional development program of pre-school science education. Findings across the different cases suggest that participating pre-school children were successfully engaged in authentic MbL activities and developed several different types of models using knowledge and experiences, as well as a variety of features of both analogical and mechanistic reasoning. I use this evidence to argue that (a)different MbL tools may afford different learning opportunities; (b)pre-school children have modeling resources that can use to utilize different tools using MbL in natural ways of young children learning (e.g.,playing).
