Their approaches to learning and perceptions of self-assessment were studied with questionnaires in the beginning and at the end of the course. The students felt that they were able to assess their performance and that self-assessment exercises helped them to learn. Their self-ratings agreed well with the teacher's grading.

Some studies focused on students’ motivation toward learning biology in general; however, the shortage of studies on the effect of animation-based instruction and small-group laboratory activities as Resource-based Instructions (RBIs) on pre-service biology teachers was realized. The present study aimed to determine the effect of resource-based Instructions on pre-service biology teachers’ academic motivation toward learning biology at private and public Universities in Rwanda. Pre-service biology teachers were grouped into three groups at a public teacher traning University and received a pre-and post-assessment.  Quasi-experimental, pre and post-test control group design was used at a public university, while a repeated measures design was used at a private university. The standard academic motivation scale for learning biology (AMSLB) yielded a Cronbach alpha coefficient of 0.71 before use. The t-Test was computed to measure the statistically significant difference between the pre-and post-assessment scores and group of RBI interventions. Multivariate analysis (MANOVA) was computed to measure the effect of RBIs vis à vis the AMSLB factors. Findings revealed no statistically significant difference (df=18, p=.458) in the motivation of learning biology of pre-service teachers before and after learning via traditional instruction at a public university. However, a statistically signficant difference was found with animation instruction (df=18, p=.002) and lab instruction (df=18, p=.014).  The motivation of learning biology increased at a public university than at a private university. However, animations and small-group lab activities increased pre-service biology teachers’ intrinsic and extrinsic—career motivation of learning biology at both universities. Therefore, the study recommends using RBIs to improve pre-service biology teachers’ motivation toward learning biology.","PeriodicalId":269228,"journal":{"name":"LUMAT: International Journal on Math, Science and Technology Education","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122741953","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The data material consisted of video transcripts of 18 students working with subtraction exercises from mathematics textbooks. The results showed that the students sometimes discovered the designed affordance and sometimes did not. The students who discovered the designed affordance sometimes used the image when performing the calculations, while others did not. Some students expressed that images in mathematics textbooks are for those who find mathematics difficult, and that completing exercises without using the images was desired. The students’ approaches to images were discussed in two specific cases: First, the students’ desire to use mathematical symbols rather than images may lead to students not discovering the mathematics content that the exercise is designed to offer. Second, the use of mathematical symbols rather than images may lead to students not discovering themselves as mathematical individuals.","PeriodicalId":269228,"journal":{"name":"LUMAT: International Journal on Math, Science and Technology Education","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131943789","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Vaikka lokitiedot mahdollistavat verkkokäyttäytymisen tutkimisen, on tätä mahdollisuutta hyödynnetty verkko-oppimisen ja -opetuksen tutkimuskontekstissa verrattain vähän. Tutkimuksessa hyödynnettiin lokitietoja verkkokurssin arvioinnissa ja kehittämisessä MOOC-ympäristössä. Tässä artikkelissa kuvataan oppimisprosessia lokitietojen avulla sekä pohditaan sitä, minkälaista ymmärrystä oppimisesta lokitiedot voivat tuottaa ja miten tällaisen tiedon voisi tulevaisuudessa valjastaa oppimisen tueksi. Tutkimusaineisto koostui matematiikan opettajien (N=58) täydennyskoulutusverkkokurssin lokitiedoista. Tutkimustulokset osoittavat, että syvällisemmät tai enemmän aikaa vaativat aktiviteetit keskeyttävät yhtenäisen opiskelun herkemmin kuin esimerkiksi videoluennot. Lyhytkestoiset videot ja nopeasti vastattavat kyselyt sen sijaan sitouttavat osallistujia yhtenäiseen opiskeluun. Vaikka suoristustavoissa on yksilöllisiä eroja, verkkokurssin kehittämistarvetta on mahdollista arvioida lokitietojen avulla. Esitämme artikkelissa vision siitä, kuinka tulevaisuudessa lokitiedot voisivat automaattisesti analysoitua, järjestelmä tunnistaisi oppimisprofiileja ja verkko-oppimisympäristö muokkautuisi automaattisesti tunnistettujen opiskelutaipumusten mukaan.

At the same time, the need for new approaches to both supporting and investigating teaching and learning have emerged. Although log information enables research of online behavior, this opportunity is not used to its full potential in the context of web-based teaching and learning. This research utilized log information in the assessment of a MOOC course and its development. This article describes the learning process with the help of log information. It also envisions what kind of understanding of the learning process log information can provide and how this understanding may be harnessed to support learning in the future. The data consisted of the log information of mathematic teachers (N=58) participating in an online continuing training course. The results show that in-depth time-consuming activities interrupt studying more easily than video lectures for example. Short videos and quick queries engage the participant in more coherent study. Although there are individual differences in the studying, less well-functioning teaching content and tasks can be recognized through log information. We present a vision of how log information can be automatically analyzed; the system would recognize learning profiles and the online environment would automatically modify itself according to the profile.

One of the most important approaches for teaching the derivative is to support students in visualizing the concept. Also, it is necessary to shift researchers and teachers’ focuses to students’ dynamic mental actions while learning derivative in order to conduct effective teaching process. With this necessity, I focused on the perspective of quantitative reasoning related to the graphical approach to the derivative. This study aims to reveal a calculus student’s mental actions related to the graphical approach to the derivative. The data were collected from a first-year calculus student engaged in the task requiring graphical interpretation of the derivative. Results showed that the student’s understanding of the slope shaped her inferences about the tangent line because the quantity of ratio is prior knowledge for learning the instantaneous rate of change. Besides, as the student had the idea of correspondence related to the concept of function, she had difficulties in interpreting the global view of the derivate. This result suggests that having global view of the derivative requires a strong understanding of function and rate.","PeriodicalId":269228,"journal":{"name":"LUMAT: International Journal on Math, Science and Technology Education","volume":"1645 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132155887","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Yet, more research is needed in this area due to the rich concept of classroom climate. In this paper, I focus on the emotional classroom climate in specific mathematics lessons, namely geometry lessons. The goals of this paper are threefold: (a) to present an analytical tool to determine the emotional classroom climate in geometry lessons using participant-produced drawings, (b) to provide insight into the emotional classroom climate in primary grade geometry lessons (Grades 3-6), and (c) to report on the differences and similarities between the grade levels regarding the emotional classroom climate. In total, 114 German primary grade students participated in the study. The emotional classroom climate was analyzed using participant-produced drawings. The results showed that the emotional classroom climate in all grades could be described as positive and relatively stable. However, positive emotional classroom climate dominated in Grade 3 geometry lessons only. Negative classroom climate was elicited in very few cases, if at all. Still, an ambivalent classroom climate (both positive and negative emotions) increased from the lower to the higher grades. Lastly, versatile implications for theory and practice are discussed regarding the methodology as well as possible future directions.","PeriodicalId":269228,"journal":{"name":"LUMAT: International Journal on Math, Science and Technology Education","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130686287","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study is to investigate if science teaching designed from the method “Question Formulation Technique” (QFT) can support the development of this ability. QFT is a model for developing students' ability to phrase and evaluate questions in general which has been developed in a US context. In this study QFT is used in a Swedish context and within upper secondary school science education. The study is an intervention study where QFT was used as part of the introduction to Diploma work in the final year of upper secondary school. During the diploma work students are expected to conduct their own scientific investigations. The data consists of video recordings of student conversations while working with the formulation of questions for inquiry as part of a research lesson designed using QFT. Data was analyzed using a pragmatic approach of combining practical epistemological analysis (PEA) and organising purposes.

A situation largely blamed on teachers' instructional approaches. Since the Relating, Experiencing, Applying, Cooperating and Transferring (REACT) strategy is reported to be an effective pedagogical approach for improving students' understanding of science concepts, in this paper, we sought to explore its effectiveness on Senior High School students' achievement in molecular genetics in Ghana. To do this, the embedded mixed methods research design was employed. Two intact biology classes selected through simple random sampling were assigned as experimental and control groups and taught with the REACT strategy and the conventional approach respectively. Quantitative data were obtained with pre-test-post-test control group design and analysed with Independent sample t-test and ANOVA. The qualitative data on students’ perception of learning with the REACT strategy was obtained through interviews and analysed thematically. The findings showed that the REACT strategy was more effective for teaching molecular genetic compared with the conventional approach. Although REACT could not bridge the gap between low and high achievers in that group, the performance of low achievers in the REACT group was at par with high achievers in the conventional group. Students perceived the opportunity to search and share information as well as relate new concepts to prior learning provided by the REACT strategy to have facilitated their understanding of concepts in molecular genetics. It is recommended that biology teachers use the REACT strategy to teach concepts students find problematic.","PeriodicalId":269228,"journal":{"name":"LUMAT: International Journal on Math, Science and Technology Education","volume":"62 25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125628587","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
