Oral Presentation at the ESERA Conference 2017 in Dublin.
Abstract: In this study, we investigated the influence of textbook images on first year high school and middle school students' drawings about change of seasons. Participating students were first taught with a short curriculum sequence about change of seasons. Then, after three months, students were randomly assigned to a treatment and control group and asked to make a drawing and write an explanation of the phenomenon. Students of the treatment group were shown a typical textbook image before completing the task. Overall, 373 students (treatment group=193; control group=180) completed the task. Drawings were analyzed using factor analysis to identify emerging models. Results indicate that, while treatment and control groups students did not differ in knowledge about change of seasons, the image significantly influenced drawings of the treatment group students. This work suggests that iconic features of textbook images may play an essential role in students' understanding of the underlying concepts

This document discusses types of teaching based on Mortimer Adler's Paideia Proposal. It focuses on research around how color can impact the teaching and learning process. Several studies found that color influences student attitudes, behaviors, and learning. It can affect attention span and sense of time. Using varied, warm colors in classrooms can make the environment more stimulating and exciting for students, which could help reduce absenteeism. Different colors also influence physiological responses like blood pressure, heart rate, and muscle tension. The document advocates that color should be used as a tool to enhance understanding in teaching.
The document discusses the Next Generation Science Standards (NGSS) for K-12 science education. It provides background on the development of the NGSS including timelines and conceptual shifts represented in the standards. The NGSS integrate science and engineering practices, crosscutting concepts, and core disciplinary ideas. Key features include performance expectations for students, coherence across grades, focusing on deeper understanding and application of content, and integrating science and engineering.

Development and validation of a Learning Progression of basic astronomy pheno...Silvia Galano
The document describes the development and validation of a learning progression for basic astronomy phenomena. It discusses:
1) The aims of developing learning progressions to improve science education and describe how student understanding develops over time.
2) Research questions about characterizing student understanding of astronomical concepts like seasons and eclipses, and developing and validating a learning progression.
3) Methods used including open response questionnaires to develop initial levels of understanding, and a multiple choice assessment to empirically validate the hypothesized learning progression levels.
The ACARISS project aims to connect schools with research laboratories to improve science education using innovative teaching methods. An evaluation of the project's effectiveness found that among students who participated: 1) Positive attitudes towards science increased, such as enjoyment of learning science and interest in future science participation. 2) Career decision-making difficulties decreased, particularly inconsistent information. 3) Career decision-making self-efficacy increased, indicating greater confidence in their ability to make decisions. The results suggest the project's teaching approach is successful in promoting interest in science careers.
This chapter introduces the importance of mathematics in daily life and careers. It discusses how students often find mathematics boring and difficult to understand. The chapter also presents background information on factors that can influence students' mathematics performance, such as attitudes, engagement, instructional methods, and beliefs about intelligence. The theoretical framework outlines theories about fixed versus growth mindsets. The conceptual framework shows how student-related factors, teacher-related factors, and mathematics performance are related. The statement of the problem indicates the study aims to determine the relationship between these factors and performance for students at a particular university.

2) It outlines the key components of PCK including subject matter knowledge, pedagogical skills, and understanding student difficulties. It also discusses different "levels" of PCK specificity from general science to specific topics.
3) The document argues that effective high school teacher training should ensure teachers have in-depth content knowledge, can relate topics across disciplines, and can meet the needs of all students regardless of their backgrounds or post-secondary plans.
This document summarizes a research study on factors affecting mathematics performance of high school students at Laguna State Polytechnic University in the 2009-2010 academic year. The study examines student-related factors like interest in mathematics, study habits, and teacher-related factors such as personality traits, teaching skills, and instructional materials. It provides background information on the importance of mathematics and reviews previous related studies. The research methodology, data collection instruments, and statistical analysis plan are also outlined.
This document discusses factors that influence whether students major in physics or astronomy based on a study of 7,505 college freshman and sophomores. It finds that female students' interest in physics increases in high school but then declines, while interest in astronomy remains steady. Interest in physics is higher for students whose parents attended college and for first-generation immigrants. The study has limitations as it relies on students recalling past interests rather than longitudinal data.
The Effect of STEM Project Based Learning on Self-Efficacy among High-School ...Nader Ale Ebrahim
Science, Technology, Engineering and Mathematics (STEM) Project-Based Learning (PjBL) is increase effectiveness, create meaningful learning and influence student attitudes in future career pursuit. There are several studies in the literature reporting different aspects of STEM into a PjBL pedagogy. However, the effect of implementing STEM PjBL in terms of improving students’ skills in self-efficacy levels in physics mechanics at high school level has not been demonstrated as expected in the previous literature. This study followed a quasi-experimental research method. Bandura’s social cognitive theory is used to assess and compare the effect of STEM PjBL with conventional teaching method on students’ self-efficacy level in learning physics among over 100 high school students. The result illustrated that STEM PjBL improve students’ self-efficacy to solve physics problem. Also, the study proposes a guideline for future research.
Conceptions and Reasonings of Beninese Learners in Solving Physics Problems I...inventionjournals
In this work, we describe the modes of reasoning of the learners in order to resolve two types of problems and involving the object "acceleration" in a scientific context and the object "rapidity" in an empirical context or everyday life. These learners are young Beninese students with a scientific G.C.E.A.Level and who have been trained according to the competency approach by qualified teachers with at least five years of experience and with course materials authorized by the inspection directorate education and secondary education. From the different analyzes (lexical and sequential), it emerges that in the resolution of these problems, the concepts, rules and formulas mobilized by these learners appear as concepts and theorems-in-act (Vergnaud, 1994) Categorized profiles and according to the contexts of investigation. Different modes of reasoning stem from their distances from the design intended for the object of investigation. If, according to Rey, Defrance and Kahn (2006) and Carette (2009), reasonings and conceptions are indispensable to be competent, it seems to us that the didactic choices prescribed by the actors of the Beninese education system in the implementation of this new approach will allow Difficult to achieve the objectives of the change of approach.
Students' understanding of astronomy concepts was compared when taught with traditional textbook images versus specially designed visual representations (VRs). Students who learned with the specially designed VRs performed better, producing more scientifically accurate drawings and explanations and scoring higher on a baseline test. The specially designed VRs were more effective at addressing student misconceptions. Future work will explore combining specially designed VRs with laboratory activities.

This study investigated how textbook images influence 373 middle and high school students' drawings about seasonal change. Students were taught about seasons and then assigned to treatment and control groups. The treatment group viewed a textbook image before drawing. Factor analysis identified models in the drawings. While knowledge about seasons did not differ between groups, the image significantly impacted the treatment group's drawings. Over 40% of treatment drawings matched the image's distance-based orbital model, rather than the correct axis tilt explanation. The results suggest textbook images can mislead students and more emphasis is needed on image design and instruction to correctly interpret them.

The document discusses a study that examined how the use of "vee-maps" can help students make connections between scientific concepts and processes in their writing. Three groups of students used vee-maps in different ways when completing biology labs over a semester. Results showed that the group using vee-maps for all three labs made the most improvement in linking concepts and processes in their writing. The study suggests vee-maps are an effective scaffold to help students develop skills in explaining science.
1) The purpose of this study was to examine the relationship between visual static models and students' written solutions to fraction problems using a large sample of student work.
2) The results indicate that common student errors relate to how students interpret the given model or their own model of the situation. Students' flexibility with visual models is related to successful written solutions.
3) Researchers hypothesize that exposure to varied mathematical representations influences students' ability to flexibly use static visual representations. Students need a solid understanding of real-world situations to successfully create and interpret visual models.
The document discusses research on teaching and learning astronomy. It finds that students struggle with spatial visualization, mental modeling, and conceptual change. Effective teaching strategies engage students in challenging prior beliefs through activities that incorporate historical discoveries and modeling. Further research is needed to evaluate strategies for developing students' spatial thinking and orientation frameworks for understanding celestial phenomena. The document concludes by recommending exemplar areas for further research, such as investigating students' thinking processes for celestial motion problems.
This document discusses science education in the United States based on several studies and assessments. It finds that according to the National Assessment of Educational Progress, only 34% of fourth graders, 30% of eighth graders, and 21% of twelfth graders are proficient in science. International assessments also show U.S. students being outperformed by students in several countries. The document then discusses different approaches to teaching science, including inquiry-based learning and concept maps, and provides research supporting the use of concept maps to improve science comprehension.
Teachers’ experiences on international learning networksSaara Nissinen
The document discusses teachers' experiences with international learning networks, which aim to promote 21st century skills through participatory learning practices connected to the real world. Three teachers participated in international design-oriented networks with Finnish and American students. The teachers found that technology supported knowledge sharing between communities but that creation of shared knowledge remained mostly local.
Application Of Systemic Approach In Initial Teaching Of Chemistry Learning T...Sabrina Ball
This document discusses a study on applying a systemic approach to teach 7th grade students the mole concept in chemistry. Students had difficulties learning the mole concept due to its abstract nature. The study divided students into "excellent", "good", and "acceptable" groups based on a pre-test, with experimental and control subgroups. Students in the experimental subgroup learned using systemics (graphical concept maps), while controls used traditional methods. Results showed systemics helped "excellent" and "acceptable" students, but not "good" students. Further research is needed on larger samples to statistically confirm these findings.

This document describes the design and development of a learning progression about stellar structure and evolution (SSE). The researchers created three levels of a learning progression based on dimensions of hydrostatic equilibrium, composition and aggregation state, and functioning and evolution. They interviewed students before and after instructional activities to map their understanding to the levels. The findings showed statistically significant shifts in students' understanding along the levels after instruction, providing evidence that the learning progression can describe how student understanding of SSE develops with instruction.

How to Make a Field Mandatory in Odoo 17Celine George
In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.
This document provides an overview of wound healing, its functions, stages, mechanisms, factors affecting it, and complications.
A wound is a break in the integrity of the skin or tissues, which may be associated with disruption of the structure and function.
Healing is the body’s response to injury in an attempt to restore normal structure and functions.
Healing can occur in two ways: Regeneration and Repair
There are 4 phases of wound healing: hemostasis, inflammation, proliferation, and remodeling. This document also describes the mechanism of wound healing. Factors that affect healing include infection, uncontrolled diabetes, poor nutrition, age, anemia, the presence of foreign bodies, etc.
Complications of wound healing like infection, hyperpigmentation of scar, contractures, and keloid formation.

Introduction
• Growing emphasis in science education research on the use of
drawings as effective tool to access students’ reasoning strategies
and mental models (Ainsworth, Prain, & Tytler, 2011)
• Researchers have used drawings as a tool to study pupils’ ability to
give meaning to the depicted representation (Cox, 2005) and to elicit
misconceptions (e.g. Vosniadou & Brewer, 1994)
• Some authors suggested that drawings are products of pictorial
conventions in cultural contexts (Ehrlén, 2008)
• Drawings may be influenced by pictures in school textbooks, which
represent for students a conventional cultural context of visual
representations (Lee, 2010)
3. Galano & al.
3ESERA CONFERENCE – DUBLIN 21-25 AUGUST 2017
Introduction
• However, until now, very little is known about
how textbook pictures affect pupils’ drawings
of a given phenomenon.
• This study addresses this issue choosing
change of season as content.
4. Galano & al.
4ESERA CONFERENCE – DUBLIN 21-25 AUGUST 2017
Research question
To what extent do textbook images influence
students’ drawings about change of seasons?
5. Galano & al.
5ESERA CONFERENCE – DUBLIN 21-25 AUGUST 2017
Theoretical framework
Students’ interpretation of science visual representations
and textbook images
• Knowledge of visual language involves the awareness of semantic and
interpretative processes at the basis of communication through visual
representations (Schnotz, 2002). To know the visual language adopted in
science implies to know how information are encoded in scientific
representations through the representational syntax
• Scientific texts can be considered in general multimodal (Lemke, 1998):
featuring different modes (verbal, mathematical, and visual), interacting
with each other
• Visual representations might foster students’ learning processes since
they preserve geometric and topological relationships with the objects
they represent (Schnotz, 2002)
6. Galano & al.
6ESERA CONFERENCE – DUBLIN 21-25 AUGUST 2017
Theoretical framework
Students’ interpretation of science visual
representations and textbook images
• All the previous studies emphasize that specific support is
needed to take full advantage of visual representations
• When such support is lacking, or when representations are
oversimplified or impoverished, the sole presence of
photographs, drawings, and diagrams in school textbooks
does not guarantee a greater effectiveness in communicating
scientific concepts (Mayer and Sims, 1994; Roth et al., 2005)
7. Theoretical framework
Students’ interpretation of astronomy textbook images
Only few studies have focused
students’ difficulty with the
interpretation of diagrams and
iconic representations of
astronomical phenomena. Most
research studies generically point
out that representations of these
phenomena are often complex or
ambiguous because they are
two-dimensional representations
of phenomena that occur in a
three-dimensional space (Kikas,
1998; Duschl, et al., 2007; Barab et al.
2000; Hansen et al., 2004)

Theoretical framework
Students-generated visual representations and
learning in science
●
To involve students in the process of generating drawings
could promote students’ memory, observation, and
imagination (Neu and Berglund, 1991; Stein and Power, 1996)
●
Drawings is a way to select and capture certain features of
the reality in order to construct pattern of reasoning about it
(Cox, 2005)

Discussion
• Results confirm that students’ drawings are influenced by
contextual factors, as textbook images
• The proposed textbook image led to a distance-based model
• More emphasis on science images’ design, and on the
development of teaching-learning sequences that might help
students correctly interpret textbook images
• Promote the use of Refutation Graphics (Mason et al., 2017) that
are images designed to activate a misconception, refute it,
and present the correct conception
• Development of Innovative images specifically designed to
avoid the reinforce of the most common misconceptions
17. Galano & al.
17ESERA CONFERENCE – DUBLIN 21-25 AUGUST 2017
Next steps
• How are students’ explanations and visual
representations about familiar astronomy phenomena
affected by different image-support conditions?
• How are students’ conceptions about familiar
astronomy phenomena affected by different image-
support conditions?
• Which iconic elements of the designed innovative
images did affect the most students’ visual
representations and explanations of familiar
astronomy phenomena?
