A key indicator for the effective use of ICT is the technological pedagogical content knowledge (TPACK) of teachers with TPACK-Practical (TPACK-P) being an important iteration related to teacher enactment of this knowledge. The purpose of this research study was to capture, portray and develop the TPACK-P proficiency levels of five Physical Sciences teachers using an empowerment evaluation (EE) approach. This study adopted a mixed-methods case study design within a pragmatic research paradigm. The existing TPACK-P levels of teachers were established by administering a questionnaire and doing classroom observations of teachers using ICT in their practice. Following a professional development programme informed by principles of EE, the same TPACK-P questionnaire was used to determine if there was a change in the teachers’ TPACK-P proficiency levels. Classroom lesson observations were also conducted at this stage to establish shifts in the competency of teachers when integrating ICT into their teaching. The results of this study showed that the EE approach that guided the professional development of the Physical Sciences teachers was effective in improving their TPACK-P proficiency levels and in empowering them to be more confident and competent when integrating ICT into their teaching. This suggests that the EE approach can be modelled in professional development efforts involving small groups of teachers.","PeriodicalId":44353,"journal":{"name":"African Journal of Research in Mathematics Science and Technology Education","volume":"10 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2023-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73202350","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}

This six-semester analysis involved 6,914 students enrolled in classes across nine Texas universities. Explored were personal circumstances associated with students' successes and failures that influenced performance in on- and off-sequence, first- and second-semester general chemistry (Chem 1 and Chem 2). Students' academic legacy based on their categorization as first generation (neither grandparent nor parent/guardian with a 4-year bachelor's degree), second generation (at least one grandparent or parent/guardian with a bachelor's degree), or third generation (at least one grandparent and at least one parent/guardian hold a bachelor's degree) was investigated. Of the students in the dataset 33.8% (n = 2,340) self-identified as Hispanic. Results for Hispanic and non-Hispanic students indicated that first-generation students struggled more with Chem 1 and Chem 2 than students in the other two legacy groups. As students' academic legacy extended, they were more apt to succeed in general chemistry. Second- and third-generation students demonstrated stronger prior high-school chemistry backgrounds and were enrolled in more advanced mathematics courses. As expected, students with stronger academic backgrounds in chemistry and mathematics scored higher on the diagnostic MUST (Math-Up Skills Test), had greater self-efficacy relative to their preparation to succeed, and reported fewer paid work hours. First-generation students on the average entered with lower diagnostic MUST scores, felt less prepared to succeed, and disclosed a greater need to be employed.","PeriodicalId":44353,"journal":{"name":"African Journal of Research in Mathematics Science and Technology Education","volume":"436 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2023-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76663603","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}

It focussed on the strategies used by children to add fractions with unlike denominators. A cross-sectional survey of Grade 8 children in schools in two districts in Ghana was used. A test on the addition of fractions with unlike denominators was administered to 543 high-, average- and low-achieving children, and their responses were categorised based on the characterisation of correct strategies by Braithwaite et al. and Siegler and Pykes. Cluster bar charts and analysis of variance were used to analyse the data. The results showed that the children’s use of correct strategies for adding proper fractions with unlike denominators was higher than their use of correct strategies for adding improper fractions with unlike denominators. Thus, the children’s procedural knowledge of the addition of proper fractions with unlike denominators was higher than that of improper fractions with unlike denominators. Conceptual knowledge of the addition of fractions with unlike denominators was much lower than procedural knowledge of the same. The less advantaged (females, rural and low achievers) used fewer correct strategies and demonstrated less procedural and conceptual knowledge. Among other recommendations, curricula and classroom teaching should emphasise conceptual knowledge and its support for procedural knowledge of the addition of fractions with unlike denominators. Research interventions focussed on the less advantaged are advised.","PeriodicalId":44353,"journal":{"name":"African Journal of Research in Mathematics Science and Technology Education","volume":"1 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2023-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82114962","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}
